• Update through Linq-to-SQL DataContext not working.

  - by Puneet Dudeja

  I have created a small test for updating table using Linq-to-SQL DataContext as follows: using (pessimistic_exampleDataContext db = new pessimistic_exampleDataContext()) { var query = db.test1s.First(t => t.a == 3); if (query.b == "a") query.b = "b"; else query.b = "a"; db.SubmitChanges(); } But after executing this code in a console application in Main method, when I select records from the table, the record is not updated. I have debugged through the code, and it is not even throwing any exception. What can be the problem ?

• LINQ to SQL Where Clause Optional Criteria

  - by RSolberg

  I am working with a LINQ to SQL query and have run into an issue where I have 4 optional fields to filter the data result on. By optional, I mean has the choice to enter a value or not. Specifically, a few text boxes that could have a value or have an empty string and a few drop down lists that could have had a value selected or maybe not... For example: using (TagsModelDataContext db = new TagsModelDataContext()) { var query = from tags in db.TagsHeaders where tags.CST.Equals(this.SelectedCust.CustCode.ToUpper()) && Utility.GetDate(DateTime.Parse(this.txtOrderDateFrom.Text)) <= tags.ORDDTE && Utility.GetDate(DateTime.Parse(this.txtOrderDateTo.Text)) >= tags.ORDDTE select tags; this.Results = query.ToADOTable(rec => new object[] { query }); } Now I need to add the following fields/filters, but only if they are supplied by the user. Product Number - Comes from another table that can be joined to TagsHeaders. PO Number - a field within the TagsHeaders table. Order Number - Similar to PO #, just different column. Product Status - If the user selected this from a drop down, need to apply selected value here. The query I already have is working great, but to complete the function, need to be able to add these 4 other items in the where clause, just don't know how!

• Is there a way to give a subquery an alias in Oracle 11g SQL?

  - by Matt Pascoe

  Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

• HQL - row identifier for pagination

  - by anna.ruk

  Does anyone know if HQL has a keyword to identify rows such as ROWID or ROWNUM? I would like to implement pagination with HQL but I am not able to use .setMaxResult() or .setFirstResult() because I don't work with the session object directly and therefore don't use the Query object but simply create my query as a string and use the .find() method. I tried using LIMIT and OFFSET in my query, but HQL seems to be ignoring these keywords and is returning the whole result to me no matter what. I'm also not able to use Hibernate criteria because it does not have support for the "HAVING" clause that appears in my query. My last resort is to restrict the result set using the ROWNUM/ROWID keyword. Does anyone else have any other suggestions?

• Microsoft SQL Server 2005 Function, passing list of start and end times

  - by Kevin

  I'd like to do had a dynamic number of one start/end time pairs passed to a function as an input parameter. The function would then use the list instead of just one start, and one end time in a select statement. CREATE FUNCTION [dbo].[GetData] ( @StartTime datetime, @EndTime datetime ) RETURNS int AS BEGIN SELECT @EndTime = CASE WHEN @EndTime > CURRENT_TIMESTAMP THEN CURRENT_TIMESTAMP ELSE @EndTime END DECLARE @TempStates TABLE (StartTime datetime NOT NULL , EndTime datetime NOT NULL , StateIdentity int NOT NULL ) INSERT INTO @TempStates SELECT StartTime , EndTime , StateIdentity FROM State WHERE StartTime <= @EndTime AND EndTime >= @StartTime RETURN 0 END

• How can I get a iterable resultset from the database using pdo, instead of a large array?

  - by Tchalvak

  I'm using PDO inside a database abstraction library function query. I'm using fetchAll(), which if you have a lot of results, can get memory intensive, so I want to provide an argument to toggle between a fetchAll associative array and a pdo result set that can be iterated over with foreach and requires less memory (somehow). I remember hearing about this, and I searched the PDO docs, but I couldn't find any useful way to do that. Does anyone know how to get an iterable resultset back from PDO instead of just a flat array? And am I right that using an iterable resultset will be easier on memory? I'm using Postgresql, if it matters in this case. . . . The current query function is as follows, just for clarity. /** * Running bound queries on the database. * * Use: query('select all from players limit :count', array('count'=>10)); * Or: query('select all from players limit :count', array('count'=>array(10, PDO::PARAM_INT))); **/ function query($sql_query, $bindings=array()){ DatabaseConnection::getInstance(); $statement = DatabaseConnection::$pdo->prepare($sql_query); foreach($bindings as $binding => $value){ if(is_array($value)){ $statement->bindParam($binding, $value[0], $value[1]); } else { $statement->bindValue($binding, $value); } } $statement->execute(); // TODO: Return an iterable resultset here, and allow switching between array and iterable resultset. return $statement->fetchAll(PDO::FETCH_ASSOC); }

• SQL Server - Get Inserted Record Identity Value when Using a View's Instead Of Trigger

  - by CuppM

  For several tables that have identity fields, we are implementing a Row Level Security scheme using Views and Instead Of triggers on those views. Here is a simplified example structure: -- Table CREATE TABLE tblItem ( ItemId int identity(1,1) primary key, Name varchar(20) ) go -- View CREATE VIEW vwItem AS SELECT * FROM tblItem -- RLS Filtering Condition go -- Instead Of Insert Trigger CREATE TRIGGER IO_vwItem_Insert ON vwItem INSTEAD OF INSERT AS BEGIN -- RLS Security Checks on inserted Table -- Insert Records Into Table INSERT INTO tblItem (Name) SELECT Name FROM inserted; END go If I want to insert a record and get its identity, before implementing the RLS Instead Of trigger, I used: DECLARE @ItemId int; INSERT INTO tblItem (Name) VALUES ('MyName'); SELECT @ItemId = SCOPE_IDENTITY(); With the trigger, SCOPE_IDENTITY() no longer works - it returns NULL. I've seen suggestions for using the OUTPUT clause to get the identity back, but I can't seem to get it to work the way I need it to. If I put the OUTPUT clause on the view insert, nothing is ever entered into it. -- Nothing is added to @ItemIds DECLARE @ItemIds TABLE (ItemId int); INSERT INTO vwItem (Name) OUTPUT INSERTED.ItemId INTO @ItemIds VALUES ('MyName'); If I put the OUTPUT clause in the trigger on the INSERT statement, the trigger returns the table (I can view it from SQL Management Studio). I can't seem to capture it in the calling code; either by using an OUTPUT clause on that call or using a SELECT * FROM (). -- Modified Instead Of Insert Trigger w/ Output CREATE TRIGGER IO_vwItem_Insert ON vwItem INSTEAD OF INSERT AS BEGIN -- RLS Security Checks on inserted Table -- Insert Records Into Table INSERT INTO tblItem (Name) OUTPUT INSERTED.ItemId SELECT Name FROM inserted; END go -- Calling Code INSERT INTO vwItem (Name) VALUES ('MyName'); The only thing I can think of is to use the IDENT_CURRENT() function. Since that doesn't operate in the current scope, there's an issue of concurrent users inserting at the same time and messing it up. If the entire operation is wrapped in a transaction, would that prevent the concurrency issue? BEGIN TRANSACTION DECLARE @ItemId int; INSERT INTO tblItem (Name) VALUES ('MyName'); SELECT @ItemId = IDENT_CURRENT('tblItem'); COMMIT TRANSACTION Does anyone have any suggestions on how to do this better? I know people out there who will read this and say "Triggers are EVIL, don't use them!" While I appreciate your convictions, please don't offer that "suggestion".

• Exclude records matching subquery

  - by Skudd

  There is probably an obvious answer to this question, but I am having one heck of a time getting anywhere with it. Consider the query: SELECT * FROM reports AS r JOIN reportvalues AS rv ON rv.report_id = r.report_id JOIN metrics AS m ON m.metric_id = rv.metric_id WHERE r.report_id NOT IN( SELECT DISTINCT report_id FROM exclude_report ) In this query, exclude_report is a view constructed in a similar manner. Now what happens is the query takes an EXTREMELY long time to execute, presumably because the subquery is being executed over each and every row in the parent query. However, I am finding no feasible means of doing this any other way. Oh great SQL wizards, please advise. I really need a way of doing this all in SQL, which I will be using in SSRS.

• Firing through HTTP a Perl script for sending signals to daemons

  - by Eric Fortis

  Hello guys, I'm using apache2 on Ubuntu. I have a Perl script which basically read the files names of a directory, then rewrites a text file, then sends a signal to a daemon. How can this be done, as secure as possible through a web-page? Actually I can run the code below, but not if I remove the comments. I'm looking for advise considering: Using HTTP Requests? How about Apache file permissions on the directory shown in code? Is htaccess enough to enable user/pass access to the cgi? Should I use a database instead of writing to a file and run a cron querying the db with permission granted to write and send the signal? Granting as less permissions as possible to the webserver. Should I set a VPN? #!/usr/bin/perl -wT use strict; use CGI; #@fileList = </home/user/*>; #read a directory listing my $query = CGI->new(); print $query->header( "text/html" ), $query->p( "FirstFileNameInArray" ), #$query->p( $fileList[0] ), #output the first file in directory $query->end_html;

• jQuery: Stopping a periodic ajax call?

  - by Legend

  I am writing a small jQuery plugin to update a set of Divs with content obtained using Ajax calls. Initially, let's assume we have 4 divs. I am doing something like this: (function($) { .... .... //main function $.fn.jDIV = { init: function() { ... ... for(var i = 0; i < numDivs; i++) { this.query(i); } this.handlers(); }, query: function(divNum) { //Makes the relevant ajax call }, handlers: function() { for(var i = 0; i < numDivs; i++) { setInterval("$.fn.jDIV.query(" + i + ")", 5000); } } }; })(jQuery); I would like to be able to enable and disable a particular ajax query. I was thinking of adding a "start" and "stop" instead of the "handlers" function and subsequently storing the setInterval handler like this: start: function(divNum) { divs[divNum] = setInterval("$.fn.jDIV.query(" + i + ")", 5000); }, stop: function(divNum) { clearInterval(divs[divNum]); } I did not use jQuery to setup and destroy the event handlers. Is there a better approach (perhaps using more of jQuery) to achieve this?

• Jquery-UI tabs : Double loading of the default tab with

  - by Stephane

  I use jqueryui-tabs to display a tabbed UI. here is how my markup looks in a MasterPage: <div id="channel-tabs" class="ui-tabs"> <ul class="ui-tabs-nav"> <li><%=Html.ActionLink("Blogs", "Index", "Blog", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, new{ title="Blog Results" }) %></li> <li><%=Html.ActionLink("Forums", "Index", "Forums", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> <li><%=Html.ActionLink("Twitter", "Index", "Twitter", new { query = Model.Query, lang = Model.SelectedLanguage, fromTo = Model.FromTo, filters = Model.FilterId }, null) %></li> </ul> <div id="Blog_Results"> <asp:ContentPlaceHolder ID="ResultPlaceHolder" runat="server"> </asp:ContentPlaceHolder> </div> If the content is loaded via ajax, I return a partial view with the content of the tab. If the content is loaded directly, I load a page that include the content in the ContentPlaceHolder. somewhat like this : <asp:Content ID="Content2" ContentPlaceHolderID="BlogPlaceHolder" runat="server"> <%=Html.Partial("Partial",Model) %> </asp:Content> //same goes for the other tabs. With this in place, if I access the url "/Forums" It loads the forum content in the Blog tab first, trigger the ajax load of the Blog tab and replace the content with the blog content. I tried putting a different placeholder for each tab, but that didn't fix everything either, since when loading "/Forums" it will sure load the forum tab, but the Blog tab will show up first. Furthermore, when using separate placeholders, If I load the "/Blogs" url, It will first load the content statically in the Blog contentplaceholder and then trigger an ajax call to load it a second time and replace it. If I just link the tab to the hashtag, then when loading the forum tabs, I won't get the blog content... How would you achieve the expected behaviour? I feel like I might have a deeper probelm in the organization of my views. Is putting the tabs in the masterpage the way to go? Maybe I should just hijax the links manually and not rely on jquery-ui tabs to do the work for me. I cannot load all tabs by default and display them using the hash tags, I need an ajax loading because it is a search process that can be long. So to sum up : /Forum should load the forum tab, and let the other tabs be loaded with an ajax call when clicking on it. /Twitter should load the twitter tab and let the other tabs.... the same goes for /Blogs and any tabs I would add later.

• encapsulation in python list (want to use " instead of ')

  - by Codehai

  I have a list of users users["pirates"] and they're stored in the format ['pirate1','pirate2']. If I hand the list over to a def and query for it in MongoDB, it returns data based on the first index (e.g. pirate1) only. If I hand over a list in the format ["pirate1","pirate"], it returns data based on all the elements in the list. So I think there's something wrong with the encapsulation of the elements in the list. My question: can I change the encapsulation from ' to " without replacing every ' on every element with a loop manually? Short Example: aList = list() # get pirate Stuff # users["pirates"] is a list returned by a former query # so e.g. users["pirates"][0] may be peter without any quotes for pirate in users["pirates"]: aList.append(pirate) aVar = pirateDef(aList) print(aVar) the definition: def pirateDef(inputList = list()): # prepare query col = mongoConnect().MYCOL # query for pirates Arrrr pirates = col.find({ "_id" : {"$in" : inputList}} ).sort("_id",1).limit(50) # loop over users userList = list() for person in pirates: # do stuff that has nothing to do with the problem # append user to userlist userList.append(person) return userList If the given list has ' encapsulation it returns: 'pirates': [{'pirate': 'Arrr', '_id': 'blabla'}] If capsulated with " it returns: 'pirates' : [{'_id': 'blabla', 'pirate' : 'Arrr'}, {'_id': 'blabla2', 'pirate' : 'cheers'}] EDIT: I tried figuring out, that the problem has to be in the MongoDB query. The list is handed over to the Def correctly, but after querying pirates only consists of 1 element... Thanks for helping me Codehai

• Data historian queries

  - by Scott Dennis

  Hi, I have a table that contains data for electric motors the format is: DATE(DateTime) | TagName(VarChar(50) | Val(Float) | 2009-11-03 17:44:13.000 | Motor_1 | 123.45 2009-11-04 17:44:13.000 | Motor_1 | 124.45 2009-11-05 17:44:13.000 | Motor_1 | 125.45 2009-11-03 17:44:13.000 | Motor_2 | 223.45 2009-11-04 17:44:13.000 | Motor_2 | 224.45 Data for each motor is inserted daily, so there would be 31 Motor_1s and 31 Motor_2s etc. We do this so we can trend it on our control system displays. I am using views to extract last months max val and last months min val. Same for this months data. Then I join the two and calculate the difference to get the actual run hours for that month. The "Val" is a nonresetable Accumulation from a PLC(Controller). This is my query for Last months Max Value: SELECT TagName, Val AS Hours FROM dbo.All_Data_From_Last_Mon AS cur WHERE (NOT EXISTS (SELECT TagName, Val FROM dbo.All_Data_From_Last_Mon AS high WHERE (TagName = cur.TagName) AND (Val > cur.Val))) This is my query for Last months Max Value: SELECT TagName, Val AS Hours FROM dbo.All_Data_From_Last_Mon AS cur WHERE (NOT EXISTS (SELECT TagName, Val FROM dbo.All_Data_From_Last_Mon AS high WHERE (TagName = cur.TagName) AND (Val < cur.Val))) This is the query that calculates the difference and runs a bit slow: SELECT dbo.Motors_Last_Mon_Max.TagName, STR(dbo.Motors_Last_Mon_Max.Hours - dbo.Motors_Last_Mon_Min.Hours, 12, 2) AS Hours FROM dbo.Motors_Last_Mon_Min RIGHT OUTER JOIN dbo.Motors_Last_Mon_Max ON dbo.Motors_Last_Mon_Min.TagName = dbo.Motors_Last_Mon_Max.TagName I know there is a better way. Ultimately I just need last months total and this months total. Any help would be appreciated. Thanks in advance

• return Queryable<T> or List<T> in a Repository<T>

  - by Danny Chen

  Currently I'm building an windows application using sqlite. In the data base there is a table say User, and in my code there is a Repository<User> and a UserManager. I think it's a very common design. In the repository there is a List method: //Repository<User> class public List<User> List(where, orderby, topN parameters and etc) { //query and return } This brings a problem, if I want to do something complex in UserManager.cs: //UserManager.cs public List<User> ListUsersWithBankAccounts() { var userRep = new UserRepository(); var bankRep = new BankAccountRepository(); var result = //do something complex, say "I want the users live in NY //and have at least two bank accounts in the system } You can see, returning List<User> brings performance issue, becuase the query is executed earlier than expected. Now I need to change it to something like a IQueryable<T>: //Repository<User> class public TableQuery<User> List(where, orderby, topN parameters and etc) { //query and return } TableQuery<T> is part of the sqlite driver, which is almost equals to IQueryable<T> in EF, which provides a query and won't execute it immediately. But now the problem is: in UserManager.cs, it doesn't know what is a TableQuery<T>, I need to add new reference and import namespaces like using SQLite.Query in the business layer project. It really brings bad code feeling. Why should my business layer know the details of the database? why should the business layer know what's SQLite? What's the correct design then?

• how can user_DEPENDENCIES read from the procedure

  If I run this query : SELECT DISTINCT U.REFERENCED_NAME, U.REFERENCED_TYPE FROM USER_DEPENDENCIES U where U.name IN('P_CREATE_T') It will give me : U.REFERENCED_NAME | U.REFERENCED_TYPE random_name_table | table If I drop this table random_name_table : drop table random_name_table and I run the dependecie query It will give me this: U.REFERENCED_NAME | U.REFERENCED_TYPE BIN$6WfJh8MWWGngQ3ATqMDOpQ==$0 | table I know the result is related to recycle bin, But what I am asking is there a way that shows the table even if its droped ? I mean shouldnt the depency query read from the procedure and not from the database ? If not is there a query that reads from the procedure and not from database ? Edit ok I will make it clear : my question USER_DEPENDENCIES read from the procedure or the database ? My second question does the recycle bin always shows ? I mean is there times where the result of the recylebin disapear ?

• Are Conditional subquery

  - by Tobias Schulte

  I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out?

• Manually wiring up unobtrusive jquery validation client-side without Model/Data Annotations, MVC3

  - by cmorganmcp

  After searching and experimenting for 2 days I relent. What I'd like to do is manually wire up injected html with jquery validation. I'm getting a simple string array back from the server and creating a select with the strings as options. The static fields on the form are validating fine. I've been trying the following: var dates = $("<select id='ShiftDate' data-val='true' data-val-required='Please select a date'>"); dates.append("<option value=''>-Select a Date-</option>"); for (var i = 0; i < data.length; i++) { dates.append("<option value='" + data[i] + "'>" + data[i] + "</option>"); } $("fieldset", addShift).append($("<p>").append("<label for='ShiftDate'>Shift Date</label>\r").append(dates).append("<span class='field-validation-valid' data-valmsg-for='ShiftDate' data-valmsg-replace='true'></span>")); // I tried the code below as well instead of adding the data-val attributes and span manually with no luck dates.rules("add", { required: true, messages: { required: "Please select a date" } }); // Thought this would do it when I came across several posts but it didn't $.validator.unobtrusive.parse(dates.closest("form")); I know I could create a view model ,decorate it with a required attribute, create a SelectList server-side and send that, but it's more of a "how would I do this" situation now. Can anyone shed light on why the above code wouldn't work as I expect? -chad

• Listing issue, GROUP mysql

  - by SethCodes

  Here is a mock-up example of Mysql table: | ID | Country | City | ________________________________ | 1 | Sweden | Stockholm | | 2 | Sweden | Stockholm | | 3 | Sweden | Lund | | 4 | Sweden | Lund | | 5 | Germany | Berlin | | 6 | Germany | Berlin | | 7 | Germany | Hamburg | | 8 | Germany | Hamburg | Notice how both rows Country and city have repeated values inside them. Using GROUP BY country, city in my PDO query, the values will not repeat while in loop. Here is PDO for this: $query = "SELECT id, city, country FROM table GROUP BY country, city"; $stmt = $db->query($query); while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : The above code will result in an output like this (some editing in-between). GROUP BY works but the country repeats: Sweden - Stockholm Sweden - Lund Germany - Berlin Germany - Hamburg Using bootstrap collapse and above code, I separate the country from the city with a simple drop down collopase. Here is code: <li> <a data-toggle="collapse" data-target="#<?= $row['id']; ?>" href="search.php?country=<?= $row['country']; ?>"> <?= $row['country']; ?> </a> <div id ="<?= $row['id']; ?>" class="collapse in"> //collapse div here <a href="search.php?city=<?= $row['city']; ?>"> <?= $row['city']; ?><br></a> </div> //end </li> It then looks something like this (once collapse is initiated): Sweden > Stockholm Sweden > Lund Germany >Berlin Germany >Hamburg Here is where I face the problem. The above lists the values Sweden and Germany 2 times. I want Sweden and Germany to only list one time, and the cities listed below, so the desired look is to be this: Sweden // Lists one time > Stockholm > Lund Germany // Lists one time >Berlin >Hamburg I have tried using DISTINCT, GROUP_CONTACT and other methods, yet none get my desired output (above). Suggestions? Below is my current full code in action: <? $query = "SELECT id, city, country FROM table GROUP BY country, city"; $stmt = $db->query($query); while($row = $stmt->fetch(PDO::FETCH_ASSOC)) : ?> <li> <a data-toggle="collapse" data-target="#<?= $row['id']; ?>" href="search.php?country=<?= $row['country']; ?>"> <?= $row['country']; ?> </a> <div id ="<?= $row['id']; ?>" class="collapse in"> //collapse div here <a href="search.php?city=<?= $row['city']; ?>"> <?= $row['city']; ?><br></a> </div> //end </li> <? endwhile ?>

  I want to query like this: select * from table where concat(',', ServiceCodes, ',') like '%,33,%'; select * from table where (','||ServiceCodes||',') like '%,33,%'; so, I wrote this code: ICriteria cri = NHibernateSessionReader.CreateCriteria(typeof(ConfigTemplateList)); cri.Add(Restrictions.Like(Projections.SqlFunction("concat", NHibernateUtil.String, Projections.Property("ServiceCodes")), "%,33,%")); I get sql similar : select * from table where (ServiceCodes) like '%,33,%'; But it is not what I want,how to do it??? thanks!

• figuring out which field to look for a value in with SQL and perl

  - by Micah

  I'm not too good with SQL and I know there's probably a much more efficient way to accomplish what I'm doing here, so any help would be much appreciated. Thanks in advance for your input! I'm writing a short program for the local school high school. At this school, juniors and seniors who have driver's licenses and cars can opt to drive to school rather than ride the bus. Each driver is assigned exactly one space, and their DLN is used as the primary key of the driver's table. Makes, models, and colors of cars are stored in a separate cars table, related to the drivers table by the License plate number field. My idea is to have a single search box on the main GUI of the program where the school secretary can type in who/what she's looking for and pull up a list of results. Thing is, she could be typing a license plate number, a car color, make, and model, someone driver's name, some student driver's DLN, or a space number. As the programmer, I don't know what exactly she's looking for, so a couple of options come to mind for me to build to be certain I check everywhere for a match: 1) preform a couple of SELECT * FROM [tablename] SQL statements, one per table and cram the results into arrays in my program, then search across the arrays one element at a time with regex, looking for a matched pattern similar to the search term, and if I find one, add the entire record that had a match in it to a results array to display on screen at the end of the search. 2) take whatever she's looking for into the program as a scaler and prepare multiple select statements around it, such as SELECT * FROM DRIVERS WHERE DLN = $Search_Variable SELECT * FROM DRIVERS WHERE First_Name = $Search_Variable SELECT * FROM CARS WHERE LICENSE = $Search_Variable and so on for each attribute of each table, sticking the results into a results array to show on screen when the search is done. Is there a cleaner way to go about this lookup without having to make her specify exactly what she's looking for? Possibly some kind of SQL statement I've never seen before?

• Sql server management studio reporting "The semaphore timeout period has expired."

  - by nis-simonsen

  On our development sql server, executing any query containing more than approximately 700 characters stalls for about 10 seconds and then reports the following error: Msg 121, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) for example, this query select * from FooTable where id = ' (.. and then 700 spaces ..) ' fails fails with the timeout error while this one select * from FooTable where id = ' (.. and then 600 spaces ..) ' fails with the expected Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. - immediately. Indeed, throwing any query, including random garbage at our dev sql server exhibits this behaviour, while any other sql server I have available acts as expected, so I would think that the query never actually gets to parsing on the server. I'm at a loss here - any hints?
