  • User's possibilities on site

    - by Lari13
    I want to build a system on the website, that allows users to do some things depend on their rating. For example I have rule for rating value X: 1 post in 3 days 10 comments in 1 day 20 votes in 2 days for rating value Y, rule may be following: 3 post in 1 day 50 comments in 1 day 30 votes in 1 day Each night I recalculate users' ratings, so I know what each user is able to do. Possibilities don't sum or reset on each rating's recalculation. One more important thing is that admin can fill concrete user's possibilities at any time. What is optimal database (MySQL) structure for desired? I can count what concrete user has done: SELECT COUNT(*) FROM posts WHERE UserID=XXX AND DateOfPost >= 'YYY' SELECT COUNT(*) FROM comments WHERE UserID=XXX AND CommentOfPost >= 'YYY' But how can I do admin filling possibilities in this case?

  • 2 table SQL Query weird results

    - by javArc
    Ok this is driving me nuts, I need to write an SQL query that will grab product information from 2 tables. The first table 'products' contains the productId, productname, quantityperunit and unitprice. Now I can search by productname and categoryname individually, but when I try to combine the 2 I get crazy results, Here's the query: "SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE '%" + searchTerm + "%' OR CategoryName LIKE '%" + searchTerm + "%' excuse the java style in there, here it is formatted better: SELECT DISTINCT productId, productname, quantityperunit, unitprice FROM products pr, categories ca WHERE pr.categoryID = ca.categoryID AND ProductName LIKE 'Tofu' OR CategoryName LIKE 'Tofu' any help would be appreciated.

  • Problem using Min(field)

    - by Todd
    have these two queries: SELECT classroomid AS crid, startdate AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid and: SELECT classroomid AS crid, Min(startdate) AS msd FROM unitTemplates where classroomid = 6 GROUP BY classroomid The second query uses the minimum function. There is only one record in my table with a classroomid of 6. The first query returns msd = 20100505, the second query returns msd = 0 (instead of the expected 20100505). If I change the "Min" to "Max" it returns the highest (and only) startdate (20100505). Why doesn't MySQL like the Min function I'm using?

  • How could I compare these database values in PHP?

    - by Dan
    So a user selects from a drop down list a value. I take this value, put it into a variable, then select from the database the ID value of that table A holding the selected value also. So now I'm trying to use that ID value to get to a many-to-many relationship table that has the selected value from table A to a different table B. The many-to-many relationship table has both IDs. How can I compare this using PHP? So it would be like: $A = $_POST['a']; $sql = "SELECT a, aID from TABLEA WHERE a = $A"; What do I do then to compare the aID with the many-to-many relationships table, then get the other ID in that table and then take that ID to get values from table B?

  • Need help with a sub query/group/order (get latest comment for each ordered topic)

    - by Scarface
    Hey guys I have a query that currently finds the latest comment for each of a user's topics and then orders topics by that comment's timestamp. What I want to do is expand on this query's use and print the latest comment for each topic. The problem with this query is that while it orders the topics correctly, it prints seemingly random comments for each topic. I am trying to implement a sub query but I am not quite sure how to approach it. I was thinking that I just had to somehow use this query to get the comments. If anyone has any ideas I would really appreciate it. Here is what I think I need to add SELECT * FROM comments where topic_id='$topic_id' ORDER BY timestamp DESC LIMIT 1 Here is the query I need to modify SELECT topic.topic_title, topic.content_type, topic.subject_id, topic.creator, topic.description, topic.topic_id,comments.message,comments.user FROM comments JOIN topic ON topic.topic_id = comments.topic_id WHERE topic.creator = '$user' AND comments.timestamp > $week GROUP BY topic_id ORDER BY MAX(comments.timestamp) DESC

  • Grails - Simple hasMany Problem - Using CheckBoxes rather than HTML Select in create.gsp

    - by gav
    My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. If I use the HTML Select then it works fine! Such as the following to make the Create page; <tr class="prop"> <td valign="top" class="name"> <label for="skills"><g:message code="volunteer.skills.label" default="Skills" /></label> </td> <td valign="top" class="value ${hasErrors(bean: volunteerInstance, field: 'skills', 'errors')}"> <g:select name="skills" from="${uk.co.bumbumtrain.Skill.list()}" multiple="yes" optionKey="id" size="5" value="${volunteerInstance?.skills}" /> </td> </tr> But I need it to work with checkboxes like this; <tr class="prop"> <td valign="top" class="name"> <label for="skills"><g:message code="volunteer.skills.label" default="Skills" /></label> </td> <td valign="top" class="value ${hasErrors(bean: volunteerInstance, field: 'skills', 'errors')}"> <g:each in="${skillInstanceList}" status="i" var="skillInstance"> <label for="${skillInstance?.name}"><g:message code="${skillInstance?.name}.label" default="${skillInstance?.name}" /></label> <g:checkBox name="skills" value="${skillInstance?.id.toString()}"/> </g:each> </td> </tr> The log output is exactly the same! With both style of form the Volunteer instance is created with the Skills correctly referenced in the 'Skills' variable. When saving, the latter fails with a null reference exception as shown at the top of this question. Hope this makes sense, thanks in advance! Gav

  • Jquery datepicker popup not closing on select date in IE8

    - by Notorious2tall
    I've got a web form with a start date field. I've tied a jquery datepicker to the txt field. Now when I choose a date in FF, the selected date is populated in the text box and the calendar popup closes. However when I do the same thing in IE8, the selected date is populated in the text box but the popup remains open. I've also noticed that a script error is generated as soon as I select a date in the popup calendar. I'm using jquery 1.3.2, jquery-ui 1.7.2, and .NET 3.5. Here's an example of my code: <script type="text/javascript"> $(document).ready(function() { $("#<%=txtStartDate.ClientID%>").datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, showOn: 'button', buttonImage: '/_layouts/images/CALENDAR.GIF', buttonImageOnly: true }); }); </script> <div id="stylized"> <asp:ValidationSummary ID="vs" runat="server" CssClass="messages-error" HeaderText=" Action required before the form can be submitted." ForeColor="" ValidationGroup="sh" /> <div class="formrow"> <div class="ms-formlabel formlabel"> <asp:Label ID="lblStartDate" runat="server" CssClass="ms-standardheader" AssociatedControlID="txtStartDate">Start Date:</asp:Label> </div> <div class="ms-formbody formfield"> <asp:RequiredFieldValidator ID="reqStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Start Date is a required field." Text="*" Display="Dynamic" ValidationGroup="sh"></asp:RequiredFieldValidator> <asp:CompareValidator ID="cvStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Date must be in the format MM/DD/YYYY" Text="*" Display="Dynamic" ValidationGroup="sh" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator> <asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox> <span class="formMessage">ex. MM/DD/YYYY</span> </div> </div> <div id="buttonrow"> <asp:Button ID="btnSubmit" runat="server" Text="Submit" CssClass="ms-ButtonHeightWidth" OnClick="Submit_Click" ValidationGroup="sh" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="ms-ButtonHeightWidth" OnClick="Cancel_Click" CausesValidation="false" /> </div> </div> Here's the script error I get in IE when I select the date: 'length' is null or not an object WebResource.axd Here's the code where the error is being thrown from: function ValidatorOnChange(event) { if (!event) { event = window.event; } Page_InvalidControlToBeFocused = null; var targetedControl; if ((typeof(event.srcElement) != "undefined") && (event.srcElement != null)) { targetedControl = event.srcElement; } else { targetedControl = event.target; } var vals; if (typeof(targetedControl.Validators) != "undefined") { vals = targetedControl.Validators; } else { if (targetedControl.tagName.toLowerCase() == "label") { targetedControl = document.getElementById(targetedControl.htmlFor); vals = targetedControl.Validators; } } var i; for (i = 0; i < vals.length; i++) { ValidatorValidate(vals[i], null, event); } ValidatorUpdateIsValid(); } It happens on the .length in the for loop at the end. Vals is null and isn't found in the previous if/else. I've stepped through the javascript and if (typeof(targetedControl.Validators) != "undefined") returns false and then if (targetedControl.tagName.toLowerCase() == "label") returns false too. Thus the length is null or not an object error. Now I'm not sure if the datepicker popup not closing in IE and the script error in the WebResources.axd file are related errors, but I'm leaning that way. Can anyone tell me why the popup isn't closing?

  • Cannot turn off autocommit in a script using the Django ORM

    - by Wes
    I have a command line script that uses the Django ORM and MySQL backend. I want to turn off autocommit and commit manually. For the life of me, I cannot get this to work. Here is a pared down version of the script. A row is inserted into testtable every time I run this and I get this warning from MySQL: "Some non-transactional changed tables couldn't be rolled back". #!/usr/bin/python import os import sys django_dir = os.path.abspath(os.path.normpath(os.path.join(os.path.dirname(__file__), '..'))) sys.path.append(django_dir) os.environ['DJANGO_DIR'] = django_dir os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings' from django.core.management import setup_environ from myproject import settings setup_environ(settings) from django.db import transaction, connection cursor = connection.cursor() cursor.execute('SET autocommit = 0') cursor.execute('insert into testtable values (\'X\')') cursor.execute('rollback') I also tried placing the insert in a function and adding Django's commit_manually wrapper, like so: @transaction.commit_manually def myfunction(): cursor = connection.cursor() cursor.execute('SET autocommit = 0') cursor.execute('insert into westest values (\'X\')') cursor.execute('rollback') myfunction() I also tried setting DISABLE_TRANSACTION_MANAGEMENT = True in settings.py, with no further luck. I feel like I am missing something obvious. Any help you can give me is greatly appreciated. Thanks!

  • Call to undefined function query() - using PDO in PHP

    - by webworm
    I have a written a script in PHP that reads from data from a MySQL database. I am new to PHP and I have been using the PDO library. I have been developing on a Windows machine using the WAMP Server 2 and all has been working well. However, when I uploaded my script to the LINUX server where it will be used I get the following error when I run my script. Fatal error: Call to undefined function query() This is the line where the error is occuring ... foreach($dbconn->query($sql) as $row) The variable $dbconn is first defined in my dblogin.php include file which I am listing below. <?php // Login info for the database $db_hostname = 'localhost'; $db_database = 'MY_DATABASE_NAME'; $db_username = 'MY_DATABASE_USER'; $db_password = 'MY_DATABASE_PASSWORD'; $dsn = 'mysql:host=' . $db_hostname . ';dbname=' . $db_database . ';'; try { $dbconn = new PDO($dsn, $db_username, $db_password); $dbconn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { echo 'Error connecting to database: ' . $e->getMessage(); } ?> Inside the function where the error occurs I have the database connection defined as a superglobal as such ... global $dbconn; I am a bit confused as to what is happening since all worked well on my development machine. I was wondering if the PDO library was installed but from what I thought it was installed by default as part of PHP v5. The script is running on an Ubuntu (5.0.51a-3ubuntu5.4) machine and the PHP version is 5.2.4. Thank you for any suggestions. I am really lost on this.

  • PHP File upload fails with blank screen when size exceeds 742 KB.

    - by user284839
    Hi friends, This is one of the most bizarre errors I've come across. So I've written a little file upload web app for my friend and it works fine for any file less than or equal to 742kB in size. Needless to say, I arrived at this precise number based on relentless testing. Weird part is that if the file size is just a few KB more, for example 743 or 750, I get an error saying "MySQL has gone away". But if it is 1MB or more, then I just get a blank screen. And it happens in less than 2 seconds after I hit the upload button. So it doesn't look like a time-out to me. I checked out the PHP.ini file for post size and upload size, they are all set to 5 MB or more. And the timeout is set to 60 seconds. The uploaded file sits in MySQL database in a field of datatype mediumblob. I tried changing that to longblob. But that didn't help either. Any help? Thanks for reading, Girish

  • What is the proper query to get all the children in a tree?

    - by Nathan Adams
    Lets say I have the following MySQL structure: CREATE TABLE `domains` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `domain` CHAR(50) NOT NULL, `parent` INT(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MYISAM AUTO_INCREMENT=10 DEFAULT CHARSET=latin1 insert into `domains`(`id`,`domain`,`parent`) values (1,'.com',0); insert into `domains`(`id`,`domain`,`parent`) values (2,'example.com',1); insert into `domains`(`id`,`domain`,`parent`) values (3,'sub1.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (4,'sub2.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (5,'s1.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (6,'s2.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (7,'sx1.s1.sub1.example.com',5); insert into `domains`(`id`,`domain`,`parent`) values (8,'sx2.s2.sub1.example.com',6); insert into `domains`(`id`,`domain`,`parent`) values (9,'x.sub2.example.com',4); In my mind that is enough to emulate a simple tree structure: .com | example / \ sub1 sub2 ect My problem is that give sub1.example.com I want to know all the children of sub1.example.com without using multiple queries in my code. I have tried joining the table to itself and tried to use subqueries, I can't think of anything that will reveal all the children. At work we are using MPTT to keep in hierarchal order a list of domains/subdomains however, I feel that there is an easier way to do it. I did some digging and someone did something similar but they required the use of a function in MySQL. I don't think for something simple like this we would need a whole function. Maybe I am just dumb and not seeing some sort of obvious solution. Also, feel free to alter the structure.

  • Does replace into have a where clause?

    - by Lajos Arpad
    I'm writing an application and I'm using MySQL as DBMS, we are downloading property offers and there were some performance issues. The old architecture looked like this: A property is updated. If the number of affected rows is not 1, then the update is not considered successful, elseway the update query solves our problem. If the update was not successful, and the number of affected rows is more than 1, we have duplicates and we delete all of them. After we deleted duplicates if needed if the update was not successful, an insert happens. This architecture was working well, but there were some speed issues, because properties are deleted if they were not updated for 15 days. Theoretically the main problem is deleting properties, because some properties are alive for months and the indexes are very far from each other (we are talking about 500, 000+ properties). Our host told me to use replace into instead of deleting properties and all deprecated properties should be considered as DEAD. I've done this, but problems started to occur because of syntax error and I couldn't find anywhere an example of replace into with a where clause (I'd like to replace a DEAD property with the new property instead of deleting the old property and insert a new to assure optimization). My query looked like this: replace into table_name(column1, ..., columnn) values(value1, ..., valuen) where ID = idValue Of course, I've calculated idValue and handled everything but I had a syntax error. I would like to know if I'm wrong and there is a where clause for replace into. I've found an alternative solution, which is even better than replace into (using simply an update query) because deletes are happening behind the curtains if I use replace into, but I would like to know if I'm wrong when I say that replace into doesn't have a where clause. For more reference, see this link: http://dev.mysql.com/doc/refman/5.0/en/replace.html Thank you for your answers in advance, Lajos Árpád

  • Call Multiple Stored Procedures with the Zend Framework

    - by Brian Fisher
    I'm using Zend Framework 1.7.2, MySQL and the MySQLi PDO adapter. I would like to call multiple stored procedures during a given action. I've found that on Windows there is a problem calling multiple stored procedures. If you try it you get the following error message: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. I found that to work around this issue I could just close the connection to the database after each call to a stored procedure: if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') { //If on windows close the connection $db->closeConnection(); } This has worked well for me, however, now I want to call multiple stored procedures wrapped in a transaction. Of course, closing the connection isn't an option in this situation, since it causes a rollback of the open transaction. Any ideas, how to fix this problem and/or work around the issue.

    Consider this piece of code: DataSet ds = new DataSet(); SQLiteDataAdapter Da = new SQLiteDataAdapter(Command); Da.Fill(ds); DataTable dt = ds.Tables[0]; bool PositionExists; if (dt.Rows.Count > 0) { PositionExists = true; } else { PositionExists = false; } if (PositionExists) { //dt.Rows[0].Field<>("Date") } Here the "Date" field is a BLOB. My question is, a. Will reading through the DataAdapter create any problems later on, when I am working with BLOBS? More, specifically, will it read the BLOB properly? b. This was the read part.Now when I am writing the BLOB to the DB,its a queue actually. I.e I am trying to store a queue in MySQLite using a BLOB. Will Conn.ExecuteNonQuery() serve my purpose? c. When I am reading the BLOB back from the DB, can I edit it as the original datatype, it used to be in C# environment i.e { Queue - BLOB - ? } {C# -MySQL - C# } So in this context, Date field was a queue, I wrote it back as a BLOB, when reading it back, can I access it(and edit) as a queue? Thank You. Soham

  • SQL server deadlock between INSERT and SELECT statement

    - by dtroy
    Hi! I've got a problem with multiple deadlocks on SQL server 2005. This one is between an INSERT and a SELECT statement. There are two tables. Table 1 and Table2. Table2 has Table1's PK (table1_id) as foreign key. Index on table1_id is clustered. The INSERT inserts a single row into table2 at a time. The SELCET joins the 2 tables. (it's a long query which might take up to 12 secs to run) According to my understanding (and experiments) the INSERT should acquire an IS lock on table1 to check referential integrity (which should not cause a deadlock). But, in this case it acquired an IX page lock The deadlock report: <deadlock-list> <deadlock victim="process968898"> <process-list> <process id="process8db1f8" taskpriority="0" logused="2424" waitresource="OBJECT: 5:789577851:0 " waittime="12390" ownerId="61831512" transactionname="user_transaction" lasttranstarted="2010-04-16T07:10:13.347" XDES="0x222a8250" lockMode="IX" schedulerid="1" kpid="3764" status="suspended" spid="52" sbid="0" ecid="0" priority="0" transcount="2" lastbatchstarted="2010-04-16T07:10:13.350" lastbatchcompleted="2010-04-16T07:10:13.347" clientapp=".Net SqlClient Data Provider" hostname="VIDEV01-B-ME" hostpid="3040" loginname="DatabaseName" isolationlevel="read uncommitted (1)" xactid="61831512" currentdb="5" lockTimeout="4294967295" clientoption1="671088672" clientoption2="128056"> <executionStack> <frame procname="DatabaseName.dbo.prcTable2_Insert" line="18" stmtstart="576" stmtend="1148" sqlhandle="0x0300050079e62d06e9307f000b9d00000100000000000000"> INSERT INTO dbo.Table2 ( f1, table1_id, f2 ) VALUES ( @p1, @p_DocumentVersionID, @p1 ) </frame> </executionStack> <inputbuf> Proc [Database Id = 5 Object Id = 103671417] </inputbuf> </process> <process id="process968898" taskpriority="0" logused="0" waitresource="PAGE: 5:1:46510" waittime="7625" ownerId="61831406" transactionname="INSERT" lasttranstarted="2010-04-16T07:10:12.717" XDES="0x418ec00" lockMode="S" schedulerid="2" kpid="1724" status="suspended" spid="53" sbid="0" ecid="0" priority="0" transcount="2" lastbatchstarted="2010-04-16T07:10:12.713" lastbatchcompleted="2010-04-16T07:10:12.713" clientapp=".Net SqlClient Data Provider" hostname="VIDEV01-B-ME" hostpid="3040" loginname="DatabaseName" isolationlevel="read committed (2)" xactid="61831406" currentdb="5" lockTimeout="4294967295" clientoption1="671088672" clientoption2="128056"> <executionStack> <frame procname="DatabaseName.dbo.prcGetList" line="64" stmtstart="3548" stmtend="11570" sqlhandle="0x03000500dbcec17e8d267f000b9d00000100000000000000"> <!-- XXXXXXXXXXXXXX...SELECT STATEMENT WITH Multiple joins including both Table2 table 1 and ....

  • ManyToManyField "table exist" error on syncdb

    - by Derek Reynolds
    When I include a ModelToModelField to one of my models the following error is thrown.

  • PHP mysqli Insert not working, but not giving any errors.

    - by asdasdas
    As the title says Im trying to do a simple insert, but nothing actually is inserted into the table. I try to print out errors, but nothing is reported. My users table has many more fields than these 4, but they should all default. $query = 'INSERT INTO users (username, password, level, name) VALUES (?, ?, ?, ?)'; if($stmt = $db -> prepare($query)) { $stmt -> bind_param('ssis', $username, $password, $newlevel, $realname); $stmt -> execute(); $stmt -> close(); echo 'Any Errors: '.$db->error.PHP_EOL; } There are no errors given, but when I go to look at the table in phpmyadmin there is not a new row added. I know for sure that the types are correct (strings and integers). Is there something really wrong here or does it have something to do with the fact that I'm ignoring other columns. I have about 8 columns in the user table.

  • Why do Unicode characters show up properly in database, but as ? when printed in Java via Hibernate?

    - by lupefiasco
    I'm writing a webapp, and interfacing with MySQL using Hibernate 3.5. Using "?????? ?????????" as my test string, I can input the string and see that it is properly persisted into the database. However, when I later pull the value out of the database and print to the console as a String, I see "?????? ?????????". If I use new OutputStreamWriter(System.out,"UTF-8"); then I get "„Éá„Çp„ÇØ„Éà„ÉÉ„Éó ·Éò·Éú·Éí·Éö·Éò·É°·É£·É†·Éò"". Why don't I see the original string? These are my hibernate.cfg.xml settings: <property name="hibernate.connection.useUnicode"> true </property> <property name="hibernate.connection.characterEncoding"> UTF-8 </property> <property name="hibernate.connection.charSet"> UTF-8 </property> and this is my database connection string: hibernate.connection.url = jdbc:mysql://localhost/mydatabase?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8

  • php - disconnecting and connecting to multiple databases

    - by Phil Jackson
    Hi, I want to be able to switch from the current db to multiple dbs though a loop: $query = mysql_query("SELECT * FROM `linkedin` ORDER BY id", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { $last_update = time() / 60; while( $rows = mysql_fetch_array( $query ) ) { $contacts_db = "NNJN_" . $rows['email']; // switch to the contacts db mysql_select_db( $contacts_db, $CON ); $query = mysql_query("SELECT * FROM `linkedin` WHERE token = '" . TOKEN . "'", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { mysql_query("UPDATE `linkedin` SET last_update = '{$last_update}' WHERE token = '" . TOKEN . "'", $CON ) or die( mysql_error() ); }else{ mysql_query("INSERT INTO `linkedin` (email, token, username, online, away, last_update) VALUES ('" . EMAIL . "', '" . TOKEN . "', '" . USERNAME . "', 'true', 'false', '$last_update')", $CON ) or die( mysql_error() ); } } mysql_free_result( $query ); } // switch back to your own mysql_select_db( USER_DB, $CON ); It does insert and update details from the other databases but it also inserts and edits data from the current users database which I dont want. Any ideas?

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.
