I'm stumped on what to cal this, there might even be
a method or pattern named for what i am trying to accomplish...
In the database, a number field is included on each table
When the DAL reads the record from the database, it is passed to
the client - work is possibly done to the record and is sent
back to the DAL for update.
A query is done against the table to retrieve the record again,
the numbers are compared - if they don't match, it is assumed the record
been modified by another user/thread/activity. An error is returned to the client stating the data has been changed.
if the numbers match, the record is updated with the number field being incremented by one.
what is this methodology called (beside crap :-) )
Hi,Our DBA group is debating production release methodology. We alwaysperfect our deployment package (typically a script) against thedatabase in a Staging environment, before executing the packageagainst Production. One side argues that the safest approach is tocreate a script containing all schema changes, data changes, storedprocs, functions, etc. Run that script against Staging until it iserror-free. Then, when you run it against Production on Release Nightyou know it will also be error-free, since Staging is a copy ofProduction. However, any changes to the deployment, such as updatesto procs (and there are always a bunch in the pre-deployment period)must be manually implemented on the script.The other side wants to take advantage of the .NET environment. Wekeep all procs, views, and functions in a Release folder on VSS,execute a Get Latest Version (Recursive) from VisualStudio, and runagainst Staging/Production. Any changes to the procs areautomatically propagated from VSS to VS, and there is no manualediting of the script. You still need a script for table and datachanges. The "script everything" side of the debate feels this methodis not as reliable, especially since when views are nested, you willget compile errors and must execute the run-on several times until allthe views compile. The "script" side feels that any errors areunacceptable in a Production environment.What is the opinion out there?Thanks!
How can I execute or access a web page from a DTS package?
Both SQL server AND website are hosted on the same server (a Dual 2.4Gz Xeon with 2Gb RAM, RAID 5 etc)
I have 2 tables in SQL server 2000 that hold orders. These need to be posted into another table at a predefined time (ie: 4:30pm) and at the same time, access a remote address (a web service) and post certain elements of the order back.
Basically, can anyone help me out on how to execute a web page from a DTS.
I do NOT want to access a DTS from a webpage, which is all I'm finding at the moment.
Hello, Question is, when I try to create relationships in SQL 7 without using the wizard..upon adding the tables I get an errror message that says "Coinitialization has not been called". What does this mean?
Hello, perhaps you guys have heard this before in the past, but here iswhat I'm looking for.I have a SQL 2000 table with Social security numbers. We need tocreate a Member ID using the Member's real SSN but since we are notallowed to use the exact SSN, we need to add 1 to each number in theSSN. That way, the new SSN would be the new Member ID.For example:if the real SSN is: 340-53-7098 the MemberID would be 451-64-8109.Sounds simply enough, but I can't seem to get it straight.I need this number to be created using a query, as this query is areport's record source.Again, any help would be appreciated it.
This seems like a basic question but I have not been able to find the answer in the help files or by searching this forum.
Is a trigger called for each row updated or is it called once for all rows updated?
for example if I have:
Code Snippet CREATE TRIGGER mytrigger
ON mytable AFTER UPDATE AS BEGIN
EXEC e-mail-me inserted, N'mytrigger', getdate() END
and I do this
Code Snippet UPDATE mytable SET mycolumn = N'whatever' WHERE ID > 5 AND ID <= 10
Assuming there is a record for each nteger value of ID, than will mytrigger run 5 times (once for each row updated) or one time (with inserted containing all 5 rows)?
When a column is evaluated against an UDF in a SELECT ... or WHERE ... It makes sense that the UDF is called for every row of the SELECT. But is it still true if the UDF is called in a subquery as below?
Code Snippet
SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) I've made a test and the SQL Profiler Trace shows that the UDF is called only once.
Can anyone confirm if my test is valid and most importantly that the UDF is called only once? FYI, I never use sub queries. This is to clarify a technical detail for our performance investigation.
Thank in advance for any help.
Here is the code to setup the test: USE NorthWind GO
CREATE TABLE dbo.UdfTest ( LineID int Identity(1,1) NOT NULL, AnyText varchar(200) COLLATE database_default NOT NULL ) GO
CREATE FUNCTION dbo.F_Bogus ( ) RETURNS @tab TABLE ( LineID int NOT NULL, AnyText varchar(100) COLLATE database_default NOT NULL) AS BEGIN INSERT @tab (LineID, AnyText) VALUES (1, 'UDF1') INSERT @tab (LineID, AnyText) VALUES (2, 'UDF2') INSERT @tab (LineID, AnyText) VALUES (3, 'UDF3') INSERT @tab (LineID, AnyText) VALUES (4, 'UDF4') INSERT @tab (LineID, AnyText) VALUES (5, 'UDF4')
RETURN END GO
Here is the capture of SQL Profiler when executing the statement: SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus())
SQL:BatchStarting SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) 51 2008-05-06 17:58:31.543 SQLtmtStarting SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) 51 2008-05-06 17:58:31.543 SPtarting SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus INSERT @tab (LineID, AnyText) VALUES (1, 'UDF1') 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus INSERT @tab (LineID, AnyText) VALUES (2, 'UDF2') 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus INSERT @tab (LineID, AnyText) VALUES (3, 'UDF3') 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus INSERT @tab (LineID, AnyText) VALUES (4, 'UDF4') 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus INSERT @tab (LineID, AnyText) VALUES (5, 'UDF4') 51 2008-05-06 17:58:31.577 SPtmtCompleted -- F_Bogus RETURN 51 2008-05-06 17:58:31.577 SQLtmtCompleted SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) 51 2008-05-06 17:58:31.543 SQL:BatchCompleted SELECT LineID, AnyText FROM dbo.UdfTest WHERE LineID IN (SELECT LineID FROM dbo.F_Bogus()) 51 2008-05-06 17:58:31.543
I have some nightly jobs that execute stored procedure to call the tables? I want to know which table are called by these stored procedures. Is it possible? Any idea will be appreciated.
I am encountering an issue which is effecting our production environment, none of our sql jobs are now saving any kind of job history, nor are the status of the jobs being saved. I have run a profiler trace and it seems as if procedure : sp_sqlagent_log_jobhistory is not being called during the execution of any of our jobs Has anyone else encountered anything similar?
In a stored procedure the following code snippet 1 checks against duplicate data being inserted. I've tested it with snippet 2 and it works as expected. However, when the procedure is called from ASP.NET the check seems ineffective. I still get the error msg. The application uses a SqlDataSource with the following parameters.
Any suggestions?
Thanks,
Bakis.

I am maintaining some C# and ASP.NET code with SQL server 2000. My code calls a stored procedure. The code is a little confusing as to the name of the SQL Server stored procedure that is calling. At this point I don't know how to trace into or debug the stored procedure. Kind of hard to do in the first place when you are not absolutely certain as to the stored proc to be called.I can take an educated guess as to which stored procedure is being called. I figure if I can deliberately make a certain stored procedure fail then this might be able to somehow give me the name of the stored proc that I am calling.So is there a way to do this. Namely make a stored procedure fail, or to return the name of the stored Proc?I would sincerely appreciate some help with this problem.

Hi All,I have a report ASP.NET page that allow users to run a report by clicking a buttion to call a store procedure to generate the report, however, the store procedure is taking a few minutes to return the data, thus I got the 'timeout' error message on my page. How do I extend the time on my page?Thanks

If I execute it from SQL Server, it returns 0. (after the error, of course). If I execute it from MS ACCess through a Pass Through Query, it returns 0. On the same server !!! How could it to make me that ? I have been thought the SP is executed entirely on the server !!!
Hello all. I have a stored procedure that seems to skip the execution of an entire line of code (which happens to be a call to execute another stored procedure), but ONLY if it is being used from C# (using the System.Data.SqlClient namespace... object: SqlCommand, etc).
Basic structure:
Event SP: top-most parent -->Calls UpdateXs SP: This is the SP that will not call his child SP ----->Calls UpdateX: This is the SP that is being ignored when called from .NET (In a loop, each iteration, max iterations 10).
(1) I can call the top-most stored procedure (Event SP) with the same arguments in Query Analyzer and all SP's will execute. (2) I can call UpdateXs SP with the same arguments that are being passed to it from Event SP in the Query Analyzer, and again, it's child sp executes (UpdateX). (3) I can also call the last child (UpdateX) directly in Query Analyzer with the same arguments that are passed in production (from executing the top-most parent in C#), and it executes correctly.
I'm positive that at no point the last child (UpdateX) is being passed NULL values. I made debug tables and before execution of an SP from within another SP, I store all the arguments in a debug table--none are null. Also, to figure out what was wrong with the last child (UpdateX) , the first statement in inserts into another debug table, just to show that that execution has made it into the sp--when the top parent is called from C#, it doesn't insert into my table (doesn't execute).
There are statements inside Event SP that execute after the sp call to UpdateXs SP. These statement always execute. Also, there are statements inside UpdateXs SP that execute after the sp call to the last child. These statement always execute too.
I am now clueless. I had developed & debugged all sp's in Query Analyzer before trying to use it live (with the C#). It's always fine in Query Analyzer, but ALWAYS skips the last sp in production.
Is there some fundamental principle I am missing here in MS SQL stored procedures? I am only 3 levels deep in SP calls, so I didn't think that would be an issue (I have made SP's that went a LOT deeper in calls than that in the past with no issues).
I am a student and is currently busy with an SQL project. I am having trouble with creating a view to calculate and display the hours worked for each call rate..
It goes...
I have two tables: rate and consultancydetail.
The rate table consists of columns named - id, time descripiton and rate.
The consultancydetail table - invoiceID, rateID date, startTime and endTime.
My view should display the rateId column and then there should be a column created in the view for the total hours.
total hours is calculated by adding the difference between startTime and endTime and then added to each total for each rateId.
PLEASE CAN SOMEONE HELP. I am new to this and know it should be a simple thing.
Hi,I have a large FoxPro table with an index that I need to be Queried from SQLServer by OLE.DB or ODBC. If I query the DBF directly a search takes 1Minute +. Is there a way I can call the data from the table and use theexisting FoxPro Index?ThanksSteve
I have some libraries (DLL) that I call from a regular console application. The data access methods get the connection string from the app.config, nothing special there.
The thing is: now I need to use the libraries inside a SSIS package. I call them from a script task, and everything is fine, except for the connection string.
Is there a way that I can get the connection string from the SSIS package configuration like I would from the app.config? Maybe some alternative to ConfigurationManager.AppSettings["ConnString"] in the DTS Runtime?
I have a task configured on the post execute event handler of a package expecting this task to be executed only once after the completion of all the other tasks in the package. But I found the task configured on the post execute event of the package getting executed as many times as the number of tasks in the package + 1 . Is there any workaround for this problem?
I have a Stored Procedure, which has a RAISERROR statement with LOG. I am calling this SP from a Job. Whenever the RAISERROR is executed, it also fails the job.. How should this be handled? The article:
http://support.microsoft.com/kb/309802 says that this has been fixed in SP4, but I am working on SQL Server 2000 SP4, but still it persists here. Can anyone please help me resolve issue? Can this be handled in Code? Or, Is it confirmed that even SP4 has not fixed this? Or is this a known issue and we need to live with it?
SP code: ---------------------------- CREATE PROCEDURE dbo.usp_DF_NA_Analytics_OOW AS BEGIN SET NOCOUNT ON
--Declare Variables DECLARE @CURRENTDATE DATETIME DECLARE @BEGINTIME DATETIME declare @feedname varchar(50) set @feedname = 'DF_NA_Analytics_OOW' SET @CURRENTDATE = CURRENT_TIMESTAMP
-- ensure there is a row for us - create 1 if it doesn't exist exec usp_datafeed_timestamp_init @feedname
SET @BEGINTIME = ( SELECT LastRunTime FROM NewAccounts.dbo.DataFeed_Timestamp WHERE TaskName = @feedname )
select oowReason.OOWTransaction_id, oowReason.Position, oowReason.ReasonCode, oowTx.UpdateDateTime from OOWTransaction oowTx (nolock) join OOWReason oowReason (nolock) on oowReason.OOWTransaction_id = oowTx.OOWTransaction_id WHERE oowTx.UpdateDateTime >= @BEGINTIME and oowTx.UpdateDateTime < @CURRENTDATE ORDER BY oowReason.OOWTransaction_id, Position
-- update the timestamp exec usp_UPD @feedname, @currentdate end ------------------------------
ALTER procedure dbo.usp_UPD (@feedname varchar(50), @lastruntime datetime) as begin set nocount on
if not exists (select * from dbo.datafeed_timestamp where lower(taskname) = lower(@feedname)) INSERT INTO Datafeed_Timestamp(TaskName, LastRunTime) VALUES(@feedname, @lastruntime ) else update Datafeed_Timestamp set LastRunTime = @lastruntime where TaskName = @feedname end ----------------------------------------
The above bcp fails consistently unless the "exec usp_UPD" is completely removed. Even if I substitute it with the update stmt instead of the SP call, it still fails.
I move the usp_UPD call and move it above the select making the select as the last command in the SP -- still fails. Removed Order by -- still fails.
The weird thing is -- several other SPs that follow the same exact format (only select query is different) - they all succeed everytime.
This above bcp fails everytime unless the usp_UPD is fully removed. I have tried putting the result dataset into a table variable and select it in the end -- still fails. several other attempt to workaround - fails -- by fails I mean "0 rows returned" from bcp -- when the UPD is removed, it returns the correct dataset. Otherwise always returns 0 rows.
Outside bcp, if I simply execute the SP from QA, it returns the correct dataset everytime. From bcp, it just doesn't like it. It returns 0 rows everytime, but does the UPD task -- the value does get updated adter execution.
When I call DeriveParameters against a function written in SQLCLR function it throws an exception. I've been working on this a little while and haven't found a fix. I understand that I could write additional code to do the same work DeriveParameters does, but it seems like this should work.
This is the exception thrown:
[InvalidOperationException: The stored procedure 'GSI.Utils.IsMatch' doesn't exist.]
The function is defined as
CREATE FUNCTION [Utils].[IsMatch](@Value [nvarchar](4000), @RegularExpression [nvarchar](4000)) RETURNS [bit] WITH EXECUTE AS CALLER AS EXTERNAL NAME [RegularExpressionsHelper].[UserDefinedFunctions].[IsMatch]
The C# function is defined as:
[Microsoft.SqlServer.Server.SqlFunction(IsDeterministic=true)] public static SqlBoolean IsMatch(SqlString Value, SqlString RegularExpression) { Regex rx = new Regex( RegularExpression.ToString() ); string s = Value.ToString();
return new SqlBoolean(rx.IsMatch(s)); }
This is the code I'm using to call DeriveParameters:
static void Main(string[] args) { using (SqlConnection conn = new SqlConnection(m_GetConnectionString())) { conn.Open();
I found that DeriveParameters seems to call sp_procedure_params_managed and when I call it myself it returns the parameters correctly for T-SQL functions, but returns no records when I specify a SQLCLR function.
I'm able to execute the function without issue and I'm able to use DeriveParameters against everything in the database except C# based functions (and I've tried others besides IsMatch). I'm attempting to run DeriveParameters from a console application and from ASP.NET, both running .NET 2.0.
I've experienced the same behavior in these versions:
SQL Server 2005 Enterprise Edition RTM (MSDN Image on Virtual Server) SQL Server 2005 Enterprise Edition SP1 (MSDN Image on Virtual Server) SQL Server 2005 Enterprise Edition SP1 + Hotfix kb918222 (MSDN Image on Virtual Server) SQL Server 2005 Developer Edition SP1
I have implemented the code from the 'Recycling Conversations' post that Remus Resanu has posted. For some reason my sender activation procedure never gets called. I thought it was working at one point but now can not get it to work. Messages are being sent correctly from sender to receiver but the c_audit_send_queue_activation procedure never gets called.
According to my code that calls 'begin conversation timer(@dlg) timeout=30;' I would think that after 30 seconds that my activated procedure would get called with a DialogTimer message but it does not. Nor does the activation procedure on the sender get called when I manually end conversations on the receiver side.
Thanks in advance for any help.

OK, I have been raking my brains with this and no solution yet. I simply want to update a field in a table given the record Id. When I try the SQL in standalone (no sp) it works and the field gets updated. When I do it by executing the stored procedure from a query window in the Express 2005 manager it works well too. When I use the stored procedure from C# then it does not work: 1. ExecuteNonQuery() always returns -1 2. When retrieving the @RETURN_VALUE parameter I get -2, meaning that the SP did not find a matching record. So, with #1 there is definitely something wrong as I would expect ExecuteNonQuery to return something meaningful and with #2 definitely strange as I am able to execute the same SQL code with those parameters from the manager and get the expected results. Here is my code (some parts left out for brevity):1 int result = 0; 2 if (!String.IsNullOrEmpty(icaoCode)) 3 { 4 icaoCode = icaoCode.Trim().ToUpper(); 5 try 6 { 7 SqlCommand cmd = new SqlCommand(storedProcedureName);(StoredProcedure.ChangeAirportName); 8 cmd.Parameters.Add("@Icao", SqlDbType.Char, 4).Value = newName; 9 cmd.Parameters.Add("@AirportName", SqlDbType.NVarChar, 50).Value = (String.IsNullOrEmpty(newName) ? null : newName); 10 cmd.Parameters.Add("@RETURN_VALUE", SqlDbType.Int).Direction = ParameterDirection.ReturnValue; 11 cmd.Connection = mConnection; // connection has been opened already, not shown here 12 cmd.CommandType = CommandType.StoredProcedure; 13 int retval = cmd.ExecuteNonQuery(); // returns -1 somehow even when RETURN n is != -1 14 result = (int)cmd.Parameters["@RETURN_VALUE"].Value; 15 16 } 17 catch (Exception ex) 18 { 19 result = -1; 20 } 21 }
And this is the stored procedure invoked by the code above:1 ALTER PROCEDURE [dbo].[ChangeAirfieldName] 2 -- Add the parameters for the stored procedure here 3 @Id bigint = null,-- Airport Id, OR 4 @Icao char(4) = null,-- ICAO code 5 @AirportName nvarchar(50) 6 AS 7 BEGIN 8 -- SET NOCOUNT ON added to prevent extra result sets from 9 -- interfering with SELECT statements. 10 SET NOCOUNT ON; 11 12 -- Parameter checking 13 IF @Id IS NULL AND @Icao IS NULL 14 BEGIN 15 RETURN -1;-- Did not specify which record to change 16 END 17 -- Get Id if not known given the ICAO code 18 IF @Id IS NULL 19 BEGIN 20 SET @Id = (SELECT [Id] FROM [dbo].[Airports] WHERE [Icao] = @Icao); 21 --PRINT @id 22 IF @Id IS NULL 23 BEGIN 24 RETURN -2;-- No airport found with that ICAO Id 25 END 26 END 27 -- Update record 28 UPDATE [dbo].[Airfields] SET [Name] = @AirportName WHERE [Id] = @Id; 29 RETURN @@ROWCOUNT 30 END
As I said when I execute standalone UPDATE works fine, but when approaching it via C# it returns -2 (did not find Id).
i have a field Count that i want it to be automatically increased by 1 whenever a SELECT stament is called. i come out with the following sql query and it works on SQL Query Analyzer:
declare @count int select @count = count+1 from pictures_posts where itemtype='3' update pictures_posts set count=@count where itemtype='3' select postID, color, count from pictures_posts where itemtype='3' go
but i am thinking it must be a much better to do this. can you guys help?
