• Can I Use ASP.NET Wizard Control to Insert Data into Multiple Tables?

  - by SidC

  Hello All, I have an ASP.NET 3.5 webforms project written in VB that involves a multi-table SQL Server insert. That is, I want the customer to input all their contact information, order details etc. into one control (thinking wizard control). Then, I want to call a stored procedure that does the insert into the respective database tables. I'm familiar and comfortable with the ASP.NET wizard control. However, all the examples I've seen in my searches pertain to inserting data into one table. Questions: 1. Given a typical order process - customer information, order information, order details - should a wizard control be used to insert data into multiple database tables? If not, what controls/workflow do you suggest? 2. I've set primary keys and indexes on my order details, orders and customers tables. Is there special stored procedure syntax to use to ensure that referential integrity is maintained through the insert process? Thanks, Sid

• MySQL Prepared Statements vs Stored Procedures Performance

  - by amardilo

  Hi there, I have an old MySQL 4.1 database with a table that has a few millions rows and an old Java application that connects to this database and returns several thousand rows from this this table on a frequent basis via a simple SQL query (i.e. SELECT * FROM people WHERE first_name = 'Bob'. I think the Java application uses client side prepared statements but was looking at switching this to the server, and in the example mentioned the value for first_name will vary depending on what the user enters). I would like to speed up performance on the select query and was wondering if I should switch to Prepared Statements or Stored Procedures. Is there a general rule of thumb of what is quicker/less resource intensive (or if a combination of both is better)

• What data structure would be the least painful DataTable replacement?

  - by MatthewMartin

  I'm storing a lot of sorted ~10 row 2 column/key value pairs in ASP.NET cache-- they're the data for dropdownlists. Right now they are all DataTables, which isn't very space efficient (the rule of thumb is 10x increase in size when data is strored in a dataset). Old Code DataTable table = dataAccess.GetDataTable(); dropDownList.DataSource = table; Hoped for new Code Unknown data = dataAccess.GetSomethingMoreSpaceEfficient(); dropDownList.DataSource = data; What pre-existing datastructures are similar enough to DataTable that would minimize code breakage and reduce the serialized size when stored in ASP.NET cache?

• How to access Sharepoint List Items using an ID

  - by GEShafer

  I am currently working on a nice table that displays the items in a list of "Tasks" on a dispForm page. Each Task is created and initially given a ProjectID depending on which project the task is for. The ProjectID is the actual ID given to the "project" when it is added to the list, therefore it is not actually a parameter in the list of projects while it is a parameter in the list of tasks. I would like to know how to use the ProjectID parameter in the task list to link to the Project list and grab the ProjectName parameter so that I can display the Project Name in the table. Currently I can not get it to work. All help is appreciated, Gale

• Inconsistent email formatting with inline css created using Javamail

  - by user1816183

  Okay, so I have a program that sends an email when it is finished running. I use inline css to format the email. This was working up until yesterday however now I am seeing different formats depending on which email account I view the email in. It coincides with an upgrade from Selenium 2.35.0 to 2.37.0 however I don't think this is my issue since I rolled back to 2.35.0 and it still happens. package tests; import java.util.Properties; import javax.mail.Message; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class TESTTEST { public static void main(String[] args) throws Exception { Properties props = new Properties(); props.put("mail.smtp.host","xxx.xxx.xxx.xxx"); Session session = Session.getInstance(props); String emailFrom="[email protected]"; String emailTo1="[email protected]"; MimeMessage message = new MimeMessage(session); message.setSubject("Testing HTML Email"); message.setFrom(new InternetAddress(emailFrom)); String htmlBody = "<STYLE>body {font-family:sans-serif,arial,helvetica,sans-serif;font-size:9pt;}" +"TABLE {border-collapse:collapse;border:1px solid black;}" +"TH {background-color:grey;color:white;padding:5px;border:1px solid black;font-size:9pt;}" +"TD {padding:5px;border:1px solid black;font-size:9pt;}" +"H3 {font-size:12pt;}" +".PASSED {background-color:#00FF00}" +".FAILED {background-color:#FF0000}" +".SKIPPED {background-color:#DEDEDE}" +".ITALIC {font-style:italic}" +"</STYLE>" + "<TABLE><TR><TD CLASS=PASSED>FAIL</TD><TD STYLE=background-color:#FF0000>FAIL</TD></TR></TABLE>"; message.setContent(htmlBody, "text/html; charset=ISO-8859-1"); message.addRecipient(Message.RecipientType.TO,new InternetAddress(emailTo1)); Transport.send(message,message.getRecipients(Message.RecipientType.TO)); System.out.println(htmlBody); System.out.println("Email Sent"); } } When I view the email in Hotmail/Outlook.com, it looks fine In Gmail In Lotus Notes Anybody able to help?

• SQL Server 2008 EF 4 - limiting database records returned using permissions?

  - by Chuck

  In our database all tables are linked back to a single table. This table has a bit column to limit whether the record is displayed. Currently the records are filtered on the code side of the website. Is there any way to set up permission so that userA would never see any record in the database where that common bit column was set to true? We are using SQL Server 2008. Alternatively we are also using entity framework 4.0 in .net 4 (in c#) if you have any ideas how it might be accomplished there? Thanks for your feedback.

• PHP looping through an array to fetch a value for each key from database (third normal form)

  - by zomboble

  I am building a system, mostly for consolidating learning but will be used in practice. I will try and verbally explain the part of the E-R diagram I am focusing on: Each cadet can have many uniformID's Each Uniform ID is a new entry in table uniform, so cadets (table) may look like: id | name | ... | uniformID 1 | Example | ... | 1,2,3 uniform table: id | notes | cadet 1 | Need new blahh | 1 2 | Some stuff needed | 1 3 | Whatever you like | 1 On second thought, looks like I wont need that third column in the db. I am trying to iterate through each id in uniformID, code: <?php $cadet = $_GET['id']; // set from URL $query = mysql_query("SELECT `uniformID` FROM `cadets` WHERE id = '$cadet' LIMIT 1") or die(mysql_error()); // get uniform needed as string // store it while ($row = mysql_fetch_array($query)) { $uniformArray = $row['uniformID']; } echo $uniformArray . " "; $exploded = explode(",", $uniformArray); // convert into an array // for each key in the array perform a new query foreach ($exploded as $key => $value) { $query(count($exploded)); $query[$key] = mysql_query("SELECT * FROM `uniform` WHERE `id` = '$value'"); } ? As I say, this is mainly for consolidation purposes but I have come up with a error, sql is saying: Fatal error: Function name must be a string in C:\wamp\www\intranet\uniform.php on line 82 line 82 is: $query[$key] = mysql_query("SELECT * FROM `uniform` WHERE `id` = '$value'"); I wasn't sure it would work so I tried it and now i'm stuck! EDIT: Thanks to everyone who has contributed to this! This is now the working code: foreach ($exploded as $key => $value) { //$query(count($exploded)); $query = mysql_query("SELECT * FROM `uniform` WHERE `id` = '$value'"); while ($row = mysql_fetch_array($query)) { echo "<tr> <td>" . $row['id'] . "</td> <td>" . $row['note'] . "</td> </tr>"; } } Added the while and did the iteration by nesting it in the foreach

• Problem with altering model attributes in controller

  - by SpawnCxy

  Hi all, Today I've got a problem when I tried using following code to alter the model attribute in the controller function userlist($trigger = 1) { if($trigger == 1) { $this->User->useTable = 'betausers'; //'betausers' is completely the same structure as table 'users' } $users = $this->User->find('all'); debug($users); } And the model file is class User extends AppModel { var $name = "User"; //var $useTable = 'betausers'; function beforeFind() //only for debug { debug($this->useTable); } } The debug message in the model showed the userTable attribute had been changed to betausers.And It was supposed to show all records in table betausers.However,I still got the data in the users,which quite confused me.And I hope someone can show me some directions to solve this problem. Regards

• Referencing outer query's tables in a subquery

  - by soulmerge

  Is it possible to reference an outer query in a subquery with MySQL? I know there are some cases where this is possible: SELECT * FROM table t1 WHERE t1.date = ( SELECT MAX(date) FROM table t2 WHERE t2.id = t1.id)` ); But I'm wondering if something like this could work: SELECT u.username, c._postCount FROM User u INNER JOIN ( SELECT p.user, COUNT(*) AS _postCount FROM Posting p --# This is the reference I would need: WHERE p.user = u.id ) c ON c.user = u.id WHERE u.joinDate < '2009-10-10'; I know I could achieve the same using a GROUP BY or by pulling the outer WHERE clause into the sub-query, but I need this for automatic SQL generation and cannot use either alternative for various other reasons.

• efficiently trimming postgresql tables

  - by agilefall

  I have about 10 tables with over 2 million records and one with 30 million. I would like to efficiently remove older data from each of these tables. My general algorithm is: create a temp table for each large table and populate it with newer data truncate the original tables copy tmp data back to original tables using: "insert into originaltable (select * from tmp_table)" However, the last step of copying the data back is taking longer than I'd like. I thought about deleting the original tables and making the temp tables "permanent", but I lose constraint/foreign key info. If I delete from the tables directly, it takes much longer. Given that I need to preserve all foreign keys and constraints, are there any faster ways of removing the older data? Thanks.

• Why won't this sql update query work?

  - by Wesley

  I have a table that has 5,000(table1) lines in it. Currently, 3,000 of them are filled up with data. The remaining values are currently null. In a separate table(table2), I have the remaining 2,000 rows of data.

• UINavigation controller problem

  - by VansFannel

  Hello. I'm developing an iPhone application and I'm trying to do this: I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar). It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google). UPDATE I don't know how where to put UINavigationController. How can I do that? Can I use a UIViewController to call a UINavigationController? Thank you.

• Navigating by foreign keys in ADO.NET Entity Framework/MySQL

  - by Werg38

  I am using ASP.NET MVC2 on top of a MySQL database in VS2008. I am using the MySQL ADO.NET connector 6.2.3 to provide the connection for the ADO.NET Entity Data Model. This is mostly working ok, however navigating via foreign keys is causing me a real headache! Here is a simplified example.. Car (Table) CarID PK Colour Doors ManufacturerID FK Manufacturer (Table) ManufacturerID PK Name In the edmx file I can see the 1-many relationship shown as a navigation property in the both the Car and Manufacturer tables. I create a Models.CarRepository that allows me to returns a IQueryable. At the View I want to be able to display the Manufacturer.Name for each car. This is not accessible via the object I get returned. What is best way to implement this? Have I encountered a limitation of the Entity Framework/MySQL combination?

• How to prevent CAST errors on SSIS ?

  - by manitra

  Hello, The question Is it possible to ask SSIS to cast a value and return NULL in case the cast is not allowed instead of throwing an error ? My environment I'm using Visual Studio 2005 and Sql Server 2005 on Windows Server 2003. The general context Just in case you're curious, here is my use case. I have to store data coming from somewhere in a generic table (key/value structure with history) witch contains some sort of value that can be strings, numbers or dates. The structure is something like this : table Values { Id int, Date datetime, -- for history Key nvarchar(50) not null, Value nvarchar(50), DateValue datetime, NumberValue numeric(19,9) } I want to put the raw value in the Value column and try to put the same value in the DateValue column when i'm able to cast it to Datetime in the NumberValue column when i'm able to cast it to a number Those two typed columns would make all sort of aggregation and manipulation much easier and faster later. That's it, now you know why i'm asking this strange question. ============ Thanks in advance for your help.

• iphone dev - how to catch exception 'NSRangeException'

  - by Brian

  In my app I try to scroll a UITableView to the top once after I updated the content of the table. However, under some circumstance, my table is EMPTY. So I got the following exception: Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (0) beyond bounds (0) for section (0).' how can I catch this exception? I tried NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; if (indexPath != nil) { [EventTable scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES]; } but it doesn't catch the exception because indexPath is not nil.

• Is it possible to create an enum whose object can't be created but can be used for readonly purpose

  - by Shantanu Gupta

  I created an enum where I stored some table names. I want it to be used to get the name of the table like ds.Tables[BGuestInfo.TableName.L_GUEST_TYPE.ToString()]. public enum TableName : byte { L_GUEST_TYPE = 0 ,L_AGE_GROUP = 1 ,M_COMPANY = 2 ,L_COUNTRY = 3 ,L_EYE_COLOR = 4 ,L_GENDER = 5 ,L_HAIR_COLOR = 6 ,L_STATE_PROVINCE = 7 ,L_STATUS = 8 ,L_TITLE = 9 ,M_TOWER = 10 ,L_CITY = 11 ,L_REGISTER_TYPE = 12 } This is my enum. Now I have not created any object of this enum so that no one can use it for other than read only purpose. For this enum to be accessible in outer classes as well I have to make it public which means some outer class can create its object as well. So what can i do so as to restrict its object creation.

• MySQL Join issue

  Hi, I have the following tables: --table sportactivity-- sport_activity_id, home_team_fk, away_team_fk, competition_id_fk, date, time (tuple example) - 1, 33, 41, 5, 2010-04-14, 05:40:00 --table teams-- team_id, team_name (tuple example) - 1, Algeria Now I have the following SQL statment that I use to extract Team A vs Team B SELECT sport_activity_id, T1.team_name AS TeamA, T2.team_name AS TeamB, DATE_FORMAT( DATE, '%d/%m/%Y' ) AS DATE, DATE_FORMAT( TIME, '%H:%i' ) AS TIME FROM sportactivity JOIN teams T1 ON home_team_fk = T1.team_id JOIN teams T2 ON ( away_team_fk = T2.team_id OR away_team_fk = '0' ) WHERE DATE( DATE ) >= CURDATE( ) ORDER BY DATE( DATE ) My problem is that when team B is empty, I am having irrelevant information .... it seems that it is returning all the combinations. I need a query that when team B is equal to 0, (this can occur in my scenario) I get only Team A - Team B (as 0) once.

• php foreach looping twice

  - by Jack

  Hi, I am trying to loop through some data from my database but it is outputting it twice. $fields = 'field1, field2, field3, field4'; $idFields = 'id_field1, id_field2, id_field3, id_field4'; $tables = 'table1, table2, table3, table4'; $table = explode(', ', $tables); $field = explode(', ', $fields); $id = explode(', ', $idFields); $str = 'Egg'; $i=1; while ($i<4) { $f = $field[$i]; $idd = $id[$i]; $sql = $writeConn->select()->from($table[$i], array($f, $idd))->where($f . " LIKE ?", '%' . $str . '%'); $string = '<a title="' . $str . '" href="' . $currentProductUrl . '">' . $str . '</a>'; $result = $writeConn->fetchAssoc($sql); foreach ($result as $row) { echo 'Success! Found ' . $str . ' in ' . $f . '. ID: ' . $row[$idd] . '.<br>'; } $i++; } Outputting: Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. Could someone please explain why it is looping through both the indexed and associative values? UPDATE I did some more playing around and tried the following. $fields = 'field1, field2, field3, field4'; $idFields = 'id_field1, id_field2, id_field3, id_field4'; $tables = 'table1, table2, table3, table4'; $table = explode(', ', $tables); $field = explode(', ', $fields); $id = explode(', ', $idFields); $str = 'Egg'; $i=1; while ($i<4) { $f = $field[$i]; $idd = $id[$i]; $sql = $writeConn->select()->from($table[$i], array($f, $idd))->where($f . " LIKE ?", '%' . $str . '%'); $string = '<a title="' . $str . '" href="' . $currentProductUrl . '">' . $str .

'.<br>'; } $i++; } The interesting thing is that this outputs the below: Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. I have also tried adding $i to the output and this outputs 2 as expected. If I change fetch(PDO::FETCH_BOTH) to fetch(PDO::FETCH_ASSOC) the output is as follows: Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: E. Success! Found Egg in field3. ID: 5. Success! Found Egg in field3. ID: 5. This has been bugging me for too long, so if anyone could help I would be very appreciative!

• Entity Framework projections

  - by David McClelland

  We are investigating the Entity Framework to see if it will meet our particular needs. Here is the scenario I am interested in: I have a large table (let's call it VeryWideRecord) which has many columns, and it has a corresponding business object (it's also called VeryWideRecord). I would like to be able to query my database for a VeryWideRecord business object, but only have values for certain columns returned by the underlying SQL. Can I do this with the Entity Framework? I am uncertain as to whether this could be done with the Entity Framework's table splitting feature, because the application needs to be able (at runtime) to change the columns that are requested. The reason for this is that we are trying to minimize the amount of information that is going across the wire. I see how this could be done using NHibernate (example), but how can I do this with the Entity Framework?

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• Many-to-one relationship in SQLAlchemy

  This is a beginner-level question. I have a catalog of mtypes: mtype_id name 1 'mtype1' 2 'mtype2' [etc] and a catalog of Objects, which must have an associated mtype: obj_id mtype_id name 1 1 'obj1' 2 1 'obj2' 3 2 'obj3' [etc] I am trying to do this in SQLAlchemy by creating the following schemas: mtypes_table = Table('mtypes', metadata, Column('mtype_id', Integer, primary_key=True), Column('name', String(50), nullable=False, unique=True), ) objs_table = Table('objects', metadata, Column('obj_id', Integer, primary_key=True), Column('mtype_id', None, ForeignKey('mtypes.mtype_id')), Column('name', String(50), nullable=False, unique=True), ) mapper(MType, mtypes_table) mapper(MyObject, objs_table, properties={'mtype':Relationship(MType, backref='objs', cascade="all, delete-orphan")} ) When I try to add a simple element like: mtype1 = MType('mtype1') obj1 = MyObject('obj1') obj1.mtype=mtype1 session.add(obj1) I get the error: AttributeError: 'NoneType' object has no attribute 'cascade_iterator' Any ideas?

• Can I use a single MySQL query to select distinct rows and then non-distinct rows if a limit hasn't

  - by Matt Rix

  I hope I'm explaining this properly, my knowledge of MySQL is quite limited. Let's say I have a table with rows that have name and shape fields. I'd like to select a bunch of rows from a table, but return all of the rows with unique shape field values first. If I have less than a certain number of rows, let's say 7, then I'd like to fill the remaining result rows with non-unique shape rows. The best way I can word it is that they're "ordered by uniqueness, and then by some other value". So, I don't want: square, square, circle, circle, rectangle, square, triangle I'd like to have: square, circle, rectangle, triangle, square, square, circle Is this possible to do using a single SQL query? I'm using MySQL with PHP, if that makes any difference. Thanks!
