• Repository, Service or Domain object - where does logic belong?

  - by betitall

  Take this simple, contrived example: UserRepository.GetAllUsers(); UserRepository.GetUserById(); Inevitably, I will have more complex "queries", such as: //returns users where active=true, deleted=false, and confirmed = true GetActiveUsers(); I'm having trouble determining where the responsibility of the repository ends. GetActiveUsers() represents a simple "query". Does it belong in the repository? How about something that involves a bit of logic, such as: //activate the user, set the activationCode to "used", etc. ActivateUser(string activationCode);

• PHP mysql_real_escape_string() returning `NULL`

  - by DavidYell

  I'm using PHP Version 5.1.6 and trying to escape a query string from my $_GET array. However my script is returning a NULL after it's escaped. It seems that mysql_escape_string() works fine, but it's deprecated, so I don't want to use it. Having checked over the phpinfo() the MySQL lib is all loaded fine from what I can see. Has anyone experienced this kind of thing before? $term = $_GET['q']; var_dump($term); // string(7) "richard" echo "<br />"; $sterm = mysql_real_escape_string($term, $db); var_dump($sterm); // NULL It's very strange to me, I can't imagine why this function wouldn't work.

• How can I replace ” with " in ASP.NET SQL?

  - by vamsivanka

  I am trying to run this SQL from ASP.NET 2005 but am getting an invalid SQL error because it has a weird character ” in it. In my code I am trying to replace ” with " but it is not doing it as the special character in the replace command is changing to ". Query: insert into userquery(description) values ('In fact, Topeka Google Mayor Bill Bunten expressed it best: “Don’t be fooled. Even Google recognizes that all roads lead to Kansas, not just yellow brick ones.”') If I copy and execute this in mysql it is working good. How can I solve this problem?

• Complicated Order By Clause?

  - by Todd

  Hi. I need to do what to me is an advanced sort. I have this two tables: Table: Fruit fruitid | received | basketid 1 20100310 2 2 20091205 3 3 20100220 1 4 20091129 2 Table: Basket id | name 1 Big Discounts 2 Premium Fruit 3 Standard Produce I'm not even sure I can plainly state how I want to sort (which is probably a big part of the reason I can't seem to write code to do it, lol). I do a join query and need to sort so everything is organized by basketid. The basketid that has the oldest fruit.received date comes first, then the other rows with the same basketid by date asc, then the basketid with the next earliest fruit.received date followed by the other rows with the same basketid, and so on. So the output would look like this: Fruitid | Received | Basket 4 20091129 Premuim Fruit 1 20100310 Premuim Fruit 2 20091205 Standard Produce 3 20100220 Big Discounts Any ideas how to accomplish this in a single execution?

• Bash intercepting wildcard in script

  - by MrRoth

  I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

• MySQL: Selecting One Record When Others Have Same Data

  - by LoganFrederick

  I have a table of cities that all share the same area code: 367 01451 Harvard Worcester Massachusetts MA 978 Eastern 368 01452 Hubbardston Worcester Massachusetts MA 978 Eastern 369 01453 Leominster Worcester Massachusetts MA 978 Eastern The table has multiple area codes, all with multiple cities. What I'd like to do is only select one city from each area code and delete any extra cities from duplicate area codes. What would be the best query to accomplish this? I believe: http://stackoverflow.com/questions/596629/mysql4-sql-for-selecting-one-or-zero-record Is coming close to what I need but didn't quite get what/how those answers were working. Note The "978" row is the "area_code" row, table name is "zip_code".

• MySQL ORDER BY returns things in (apparently) random order !?

  - by Luke H

  The following query: SELECT DISTINCT ClassName FROM SiteTree ORDER BY ClassName is returning things in no apparent order! I get the same result whether I quote column/table names, or use DISTINCT or not, or add ASC or DESC. I assumed the indexes might be broken, or something like this, so tried dropping and recreating. Also tried REPAIR TABLE and CHECK TABLE. The table collation is set to latin1_swedish_ci. All the textual columns are set to use UTF-8 and collation is set to utf8_general_ci What could be causing this?

• How to use SSRS to retrieve HTML snippets with embedded images the easy way

  - by Ram

  I have a web-app that retrieves reports from our SSRS server dynamically - we hit a URL and out pops some HTML4.0 which I stuff into a div for the user to view. I recently tried adding a report that has an embedded image (in the RDL itself) and the image doesn't make it through. What does make it through is an IMG SRC reference back to the SSRS box but we do not allow end users to hit the SSRS box directly... users query the web-app and the web-app interacts with the SSRS service. There is an option to render in MHTML (note that we typically use rs:command=RenderHTML with rs:format=HTML4.0) - the blob returned appears to be valid MIME but does not seem friendly for stuffing into a DIV... am I missing something obvious? My next step is to parse the MIME, swizzle the references and stuff the whole thing back into the page but I feel like this is the hardway. What is the easy way to retrieve HTML snippet reports out of SSRS with embedded images?

• check for several conditions when a user logs in

  - by paul

  I would like to accomplish the following: If a username or password field is null, notify the user. If user name already exists, do not insert into the database and notify user to create a different name. if the username is unique and password is not null, return the username to the user. As of now it always returns "Please enter a different user name." I believe the issue has to do with the database query but I am not sure. If anyone can have a look and see if I am making an error, I greatly appreciate it, thanks. if ($userName or $userPassword = null) { echo "Please enter a user name and password or return to the homepage."; } elseif (mysql_num_rows(mysql_query("SELECT count(userName) FROM logininfo WHERE userName = '$userName'")) ==1) { echo "Please enter a different user name."; } elseif ($userName and $userPassword != null) { echo "Your login name is: $userName"; }

• MySQL Returns wrong values on SELECT statement

  - by Andrew K

  All, I'm wondering if this is a MySQL bug, but since I've seen others playing with larger numbers than this, I'm thinking I'm doing something wrong here. Here is my table structure for the table I'm querying: mysql describe ipspace6\G ************* 1. row ************* Field: id Type: decimal(39,0) unsigned Null: NO Key: Default: NULL Extra: ************* 2. row ************* Field: addr Type: decimal(39,0) unsigned Null: NO Key: PRI Default: 0 Extra: ************* 3. row ************* Field: netmask Type: decimal(39,0) unsigned Null: NO Key: Default: 0 Extra: ************* 4. row ************* Field: subnet Type: int(4) Null: NO Key: Default: NULL Extra: Now, I run a simple SELECT statement against the "id" column: mysql SELECT id FROM ipspace6 WHERE id='50552019118453823914642686339427860480'; +----------------------------------------+ | id | +----------------------------------------+ | 50552019118453823730175245602332344320 | | 50552019118453823730175245602332344320 | | 50552019118453823914642686339427860480 | | 50552019118453823914642686339427860480 | +----------------------------------------+ ...What the heck is going on here? Two of these results are valid, and two definitely are not. It's not like I'm doing some super-complex nested query or anything, this is simple stuff, and it's driving me insane. Help, anyone?

• Actual SQL statement after bind variables specified

  - by bioffe

  I am trying to log every SQL statement executed from my scripts. However I contemplate one problem I can not overcome. Is there a way to compute actual SQL statement after bind variables were specified. In SQLite I had to compute the statement to be executed manually, using code below: def __sql_to_str__(self, value,args): for p in args: if type(p) is IntType or p is None: value = value.replace("?", str(p) ,1) else: value = value.replace("?",'\'' + p + '\'',1) return value It seems CX_Oracle has cursor.parse() facilities. But I can't figure out how to trick CX_Oracle to compute my query before its execution.

• What's the best way to test MSSQL connection programmatically?

  - by backslash17

  I need to develop a single routine that will be fired each 5 minutes to check if a list of MSSQL servers (10 to 12) are up and running. I can try to obtain a simple query in each one of the servers but this means that I have to create a table, view or stored procedure in every server, even if I use any already made SP I need to have a registered user in each server too. The servers are not in the same phisical location so having those requirements would be a complex task. Is there a way to simply "ping" from c# one MSSQL server? Thanks in advance!

• Is JPA + EJB to much slow (or heavy) for over Internet transactions?

  - by Xavier Callejas

  Hi, I am developing a stand-alone java client application that connects to a Glassfish v3 application for JPA/EJB facade style transactions. In other words, my client application do not connect directly to the database to CRUD, but it transfers JPA objets using EJB stateless sessions. I have scenarios where this client application will be used in an external network connected with a VPN over Internet with a client connection of 512kbp/DSL, and a simple query takes so much time, I'm seeing the traffic graph and when I merge a entity in the client application I see megabytes of traffic (I couldn't believe how a purchase order entity could weight more than 1 mb). I have LAZY fetch in almost every many-to-many relationship, but I have a lot of many-to-one relationships between entities (but this is the great advantage of JPA!). Could I do something to accelerate the the speed of transactions between JPA/EJB server and the remote java client? Thank you in advance.

• Selecting previous and next row using sp

  - by davor

  I want to select previous and next row from table based on current id. I send current id to stored procedure and use this query: -- previous select top 1 id from table where id < @currentId order by id desc -- next select top 1 id from table where id < @currentId order by id asc The problem is when I send currentId which is the last id in the table and want to select next row. Then is nothing selected. Same problem for previous row, when I send currentId which is first id in table Is it possible to solve this in sql without additional queries?

• Wordpress parses wp_posts.post_content before rendering?

  - by John

  I noticed that when I call the the_post() or the_content() function from my wordpress template, it automatically parses the database data to replace new lines with <br/>, wraps the text with <p> tags etc...There's probably some kind of "format" function within the_post() or the_content(). I wrote a query to directly get posts from the wp_posts. I then print it out like <?php $results = $wp->get_results($sql) foreach($results as $row) echo $row->post_content; ?> Clearly, this data is not parsed by wordpress' "format" function. What is the proper way to output this content such that it undergoes the same "formatting" functions as the_post() or the_content()?

• SEO URL Structure

  - by Neil

  Based on the following example URL structure: mysite.com/mypage.aspx?a=red&b=green&c=blue Pages in the application use ASP.net user controls and some of these controls build a query string. To prevent duplicate keys being created e.g. &pid=12&pid=10, I am researching methods of rewriting the URL: a) mysite.com/mypage.aspx/red/green/blue b) mysite.com/mypage.aspx?controlname=a,red|b,green|c,blue Pages using this structure would be publishing content that I would like to get indexed and ranked - articles and products (8,000 products to start, with thousands more being added later) My gut instinct tells me to go with the first method, but would it would be overkill to add all that infrastructure if the second method will accomplish my goal of getting pages indexed AND ranked. So my question, looking at the pro's and con's, Google Ranking, time to implement etc. which method should I use? Thanks!

• does a git repository have its own local value for core.autocrlf that overrides the global one?

  - by Warren P

  As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

• SQLITE - INSERT does not return error but no data is inserted.

  I am attempting to insert data into a local SQLITE database file from a C# application. The transaction does not throw any errors but the data is not inserted.

Command's transaction property is null.. var command = new SQLiteCommand(insert.BuildInsert(tableName,keyValuePairs),Connection); command.ExecuteNonQuery();

• Storing dates i Train schedule MYSQL

  - by App_beginner

  Hi I have created a train schedule database in MYSQL. There are several thousand routes for each day. But with a few exceptions most of the routes are similar for every working day, but differ on weekends. At this time I basically update my SQL tables at midnight each day, to get the departures for the next 24 hours. This is however very inconvenient. So I need a way to store dates in my tables so I don't have to do this every day. I tried to create a separate table where I stored dates for each routenumber (routenumbers are resetted each day), but this made my query so slow that it was impossible to use. Does this mean I would have to store my departure and arrival times as datetimes? In that case the main table containing routes would have several million entries. Or is there another way? My routetable looks like this: StnCode (referenced in seperate Station table) DepTime ArrTime Routenumber legNumber

• Why is selecting specified columns, and all, wrong in Oracle SQL?

  - by TomatoSandwich

  Say I have a select statement that goes.. select * from animals That gives a a query result of all the columns in the table. Now, if the 42nd column of the table animals is is_parent, and I want to return that in my results, just after gender, so I can see it more easily. But I also want all the other columns. select is_parent, * from animals This returns ORA-00936: missing expression. The same statement will work fine in Sybase, and I know that you need to add a table alias to the animals table to get it to work ( select is_parent, a.* from animals ani), but why must Oracle need a table alias to be able to work out the select?

• Snapshot on, still deadlocks, ROWLOCK

  - by Patto

  I turned snapshot isolation on in my database using the following code ALTER DATABASE MyDatabase SET ALLOW_SNAPSHOT_ISOLATION ON ALTER DATABASE MyDatabase SET READ_COMMITTED_SNAPSHOT ON and got rid off lots of deadlocks. But my database still produces deadlocks, when I need to run a script every hour to clean up 100,000+ rows. Is there a way I can avoid deadlocks in my cleanup script, do I need to set ROWLOCK specifically in that query? Is there a way to increase the number of row level locks that a database uses? How are locks promoted? From row level to page level to table level? My delete script is rather simple: delete statvalue from statValue, (select dateadd(minute,-60, getdate()) as cutoff_date) cd where temporaryStat = 1 and entrydate < cutoff_date Right now I am looking for quick solution, but a long term solution would be even nicer. Thanks a lot, Patrikc

• Multiple conditions with will_paginate

  - by user363243

  I am using will_paginate for pagination but I can't seem to use more than one condition at a time. For example, if I want to have a sql query that ends in "Where office_id = 5", then it's pretty straight forward, I can do that. but what if I want to do "Where office_id = 5 AND primary_first = 'Mark'"? I can't do that. I have no idea how to enter multiple conditions. Can you help?? Below is an example of my code: def self.search(search, page, office_id) paginate :per_page => 5, :page => page, :conditions => ['office_id', "%#{office_id}"], # + ' and primary_first like ?', "%#{params[:search]}%"], #:conditions => ['primary_first', "%#{search}%"], :order => 'created_at' end Thank you for your help!
