• Exporting query results to a file on the fly

  - by ercan

  Hi all, I need to export the results of a query to a csv file in an FTP folder. Is it possible to achieve this within a stored procedure? If yes, comes yet another constraint: can I achieve this without sysadmin privileges, aka without using xp_cmdshell + BCP utility? If no to 2., does the caller have to have sysadmin privileges or would it suffice if the SP owner has sysadmin privileges? Here are some more details to the problem: The SP must export and transfer the file on the fly and raise error if something went wrong. The caller must get a response immediately, i.e. in case of no error, he can assume that the results are successfully transferred to the folder. Therefore, a DTS/SSIS job that runs every N minutes is not an option. I know the problem smells like I will have to do this at application level, but I would be more than happy if all those stuff could be done from T-SQL.

• Don't display dynamic query in result

  - by Tom Andrews

  Hi all, Is it possible to hide a dynamic query from the result sets provided from a Stored Procedure? I am using the @@rowcount of the dynamic query to set a variable that is used to determine whether another query runs or not. The other query is used by code that I cannot change - hence why I am changing the Stored Procedure. The dynamic query returns as the first result set from the Stored Procedure is now the result of the dynamic query which currently is "breaking" the calling code. Thanks in advance

• C#: proprietary DLLs requiring access to my assemblies

  - by Craig Johnston

  My solution uses a proprietary assembly, which when debugging the solution throws an Exception saying it can't find an assembly that is meant to be one of the projects in my solution. I cannot add a reference to the proprietary assembly because all I have is the DLL. When I compile everything into a single application directory and run the app it works fine, but I want to debug. Where should assemblies be placed if you want a proprietary assembly in the solution to see them? I assume the issue is that there is no path specified and it is just looking in a default directory of some kind.

• Obtain Update Table Lock at start of Stored Procedure in SQL Server

  - by Jim Hurne

  I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

• service broker message process order

  - by Blootac

  Everywhere I read says that messages handled by the service broker are processed in the order that they arrive, and yet if you create a table, message type, contract, service etc , and on activation have a stored proc that waits for 2 seconds and inserts the msg into a table, set the max queue readers to 5 or 10, and send 20 odd messages I can see in the table that they are inserted out of order even though when I insert them into the queue and look at the contents of the queue I can see that the messages are all in the right order. Is it due to the delay waitfor waiting for the nearest second and each thread having different subsecond times and then fighting for a lock or something? The reason i've got a delay in there is to simulate delays with joins etc Thanks demo code: --create the table and service broker CREATE TABLE test ( id int identity(1,1), contents varchar(100) ) CREATE MESSAGE TYPE test CREATE CONTRACT mycontract ( test sent by initiator ) GO CREATE PROCEDURE dostuff AS BEGIN DECLARE @msg varchar(100); RECEIVE TOP (1) @msg = message_body FROM myQueue IF @msg IS NOT NULL BEGIN WAITFOR DELAY '00:00:02' INSERT INTO test(contents)values(@msg) END END GO ALTER QUEUE myQueue WITH STATUS = ON, ACTIVATION ( STATUS = ON, PROCEDURE_NAME = dostuff, MAX_QUEUE_READERS = 10, EXECUTE AS SELF ) create service senderService on queue myQueue ( mycontract ) create service receiverService on queue myQueue ( mycontract ) GO --********************************************************** --now insert lots of messages to the queue DECLARE @dialog_handle uniqueidentifier BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>1</test>'); BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>2</test>') BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>3</test>') BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>4</test>') BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>5</test>') BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>6</test>') BEGIN DIALOG @dialog_handle FROM SERVICE senderService TO SERVICE 'receiverService' ON CONTRACT mycontract; SEND ON CONVERSATION @dialog_handle MESSAGE TYPE test ('<test>7</test>')

• Tentative date casting in tsql

  - by Tewr

  I am looking for something like TRYCAST in TSQL or an equivalent method / hack. In my case I am extracting some date data from an xml column. The following query throws "Arithmetic overflow error converting expression to data type datetime." if the piece of data found in the xml cannot be converted to datetime (in this specific case, the date is "0001-01-01" in some cases). Is there a way to detect this exception before it occurs? select [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'datetime') FROM Customers An example of what I am trying to achieve in pseudocode with an imagined tsql function TRYCAST(expr, totype, defaultvalue): select TRYCAST( [CustomerInfo].value('(//*:InceptionDate/text())[1]', 'nvarchar(100)'), datetime, null) FROM Customers

• Optimzing TSQL code

  - by adopilot

  My job is the maintain one application which heavy use SQL server (MSSQL2005). Until now middle server stores TSQL codes in XML and send dynamic TSQL queries without using stored procs. As I am able change those XML queries I want to migrate most of my queries to stored procs. Question is folowing: Most of my queries have same Where conditions against one table Sample: Select ..... from .... where .... and (a.vrsta_id = @vrsta_id or @vrsta_id = 0) and (a.podvrsta_id = @podvrsta_id or @podvrsta_id = 0) and (a.podgrupa_2 = @podgrupa2_id or @podgrupa2_id = 0) and ( (a.id in (select art_id from osobina_veze where podosobina_id in (select ado from dbo.fn_ado_param_int(@podosobina)) group by art_id having count(art_id)= @podosobina_count )) or ('0' = @podosobina) ) They also have same where conditions on other table. How I should organize my code ? What is proper way ? Should I make table valued function that I will use in all queries or use #Temp tables and simple inner join my query to that each time when proc executing? or use #temp filed by table valued function ? or leave all queries with this large where clause and hope that index is going to do their jobs. or use WITH(statement)

• How to get resultset with stored procedure calls over two linked servers?

  - by räph

  I have problems filling a temporary table with the resultset from a procedure call on a linked server, in which again a procedure on another server is called. I have a Stored Procedure sproc1 with the following code, which calls another procedure sproc2 on a linked server. SET @sqlCommand = 'INSERT INTO #tblTemp ( ModuleID, ParamID) ' + '( SELECT * FROM OPENQUERY(' + @targetServer + ', ' + '''SET FMTONLY OFF; EXEC ' + @targetDB + '.usr.sproc2 ' + @param + ''' ) )' exec ( @sqlCommand ) Now in the called sproc2 I again call a third procedure sproc3 on another linked server, which returns my resultset. SET @sqlCommand = 'EXEC ' + @targetServer +'.database.usr.sproc3 ' + @param exec ( @sqlCommand ) The whole thing doen't work, as I get an SQL error 7391 The operation could not be performed because OLE DB provider "%ls" for linked server "%ls" was unable to begin a distributed transaction. I already checked the hints at this microsoft article, but without success. But maybe, I can change the code in sproc1. Would there be some alternative to the temp table and the open query? Just calling stored procedures from server A to B to C and returning the resultset is working (I do this often in the application). But this special case with the temp table and openquery doesn't work! Or is it just not possible what I am trying to do? The microsft article states: Check the object you refer on the destination server. If it is a view or a stored procedure, or causes an execution of a trigger, check whether it implicitly references another server. If so, the third server is the source of the problem. Run the query directly on the third server. If you cannot run the query directly on the third server, the problem is not actually with the linked server query. Resolve the underlying problem first. Is this my case? PS: I can't avoid the architecture with the three servers.

• Sql Server string to date conversion

  - by JosephStyons

  I want to convert a string like this: '10/15/2008 10:06:32 PM' into the equivalent DATETIME value in Sql Server. In Oracle, I would say this: TO_DATE('10/15/2008 10:06:32 PM','MM/DD/YYYY HH:MI:SS AM') This question implies that I must parse the string into one of the standard formats, and then convert using one of those codes. That seems ludicrous for such a mundane operation. Is there an easier way?

• Prepare and import data into existing database

  - by Álvaro G. Vicario

  I maintain a PHP application with SQL Server backend. The DB structure is roughly this: lot === lot_id (pk, identify) lot_code building ======== buildin_id (pk, identity) lot_id (fk) inspection ========== inspection_id (pk, identify) building_id (fk) date inspector result The database already has lots and buildings and I need to import some inspections. Key points are: It's a one-time initial load. Data comes in an Excel file.

• Stored Procedure for Multi-Table Insert Error: Cannot Insert the Value Null into Column

  Good Evening All, I've created the following stored procedure: CREATE PROCEDURE AddQuote -- Add the parameters for the stored procedure here AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; Declare @CompanyName nvarchar(50), @Addr nvarchar(50), @City nvarchar(50), @State nvarchar(2), @Zip nvarchar(5), @NeedDate datetime, @PartNumber float, @Qty int -- Insert statements for procedure here Insert into dbo.Customers (CompanyName, Address, City, State, ZipCode) Values (@CompanyName, @Addr, @City, @State, @Zip) Insert into dbo.Orders (NeedbyDate) Values(@NeedDate) Insert into dbo.OrderDetail (fkPartNumber,Qty) Values (@PartNumber,@Qty) END GO When I execute AddQuote, I receive an error stating: Msg 515, Level 16, State 2, Procedure AddQuote, Line 31 Cannot insert the value NULL into column 'ID', table 'Diel_inventory.dbo.OrderDetail'; column does not allow nulls. INSERT fails. The statement has been terminated. I understand that I've set Qty field to not allow nulls and want to continue doing so. However, are there other syntax changes I should make to ensure that this sproc works correctly? Thanks, Sid

• Strange Values in SYS.DM_TRAN_LOCKS table RESOURCE_ASSOCIATED_ENTITY_ID column

  - by AJM

  I’ve been trying to understand some strange values in the RESOURCE_ASSOCIATED_ENTITY_ID column of SYS.DM_TRAN_LOCKS when RESOURCE_TYPE is “OBJECT”. Although these should be object Ids, I cannot determine what object they actually refer to. I’ve tried everything I can think of, including querying all system tables with columns of type INT and BIGINT to see if I can find the value. No luck. The funny values actually appear in SYS.DM_TRAN_LOCKS, SYS.SYSLOCKINFO and SP_LOCK.

• What is happening in this T-SQL code? (Concatenting the results of a SELECT statement)

  - by Ben McCormack

  I'm just starting to learn T-SQL and could use some help in understanding what's going on in a particular block of code. I modified some code in an answer I received in a previous question, and here is the code in question: DECLARE @column_list AS varchar(max) SELECT @column_list = COALESCE(@column_list, ',') + 'SUM(Case When Sku2=' + CONVERT(varchar, Sku2) + ' Then Quantity Else 0 End) As [' + CONVERT(varchar, Sku2) + ' - ' + Convert(varchar,Description) +'],' FROM OrderDetailDeliveryReview Inner Join InvMast on SKU2 = SKU and LocationTypeID=4 GROUP BY Sku2 , Description ORDER BY Sku2 Set @column_list = Left(@column_list,Len(@column_list)-1) Select @column_list ---------------------------------------- 1 row is returned: ,SUM(Case When Sku2=157 Then Quantity Else 0 End) As [157 -..., SUM(Case ... The T-SQL code does exactly what I want, which is to make a single result based on the results of a query, which will then be used in another query. However, I can't figure out how the SELECT @column_list =... statement is putting multiple values into a single string of characters by being inside a SELECT statement. Without the assignment to @column_list, the SELECT statement would simply return multiple rows. How is it that by having the variable within the SELECT statement that the results get "flattened" down into one value? How should I read this T-SQL to properly understand what's going on?

• Different execution plan for similar queries

  - by Graham Clements

  I am running two very similar update queries but for a reason unknown to me they are using completely different execution plans. Normally this wouldn't be a problem but they are both updating exactly the same amount of rows but one is using an execution plan that is far inferior to the other, 4 secs vs 2 mins, when scaled up this is causing me a massive problem. The only difference between the two queries is one is using the column CLI and the other DLI. These columns are exactly the same datatype, and are both indexed exactly the same, but for the DLI query execution plan, the index is not used. Any help as to why this is happening is much appreciated. -- Query 1 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail AS b WHERE a.DLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a -- Query 2 UPDATE a SET DestKey = ( SELECT TOP 1 b.PrefixKey FROM refPrefixDetail b WHERE a.CLI LIKE b.Prefix + '%' ORDER BY len(b.Prefix) DESC ) FROM CallData AS a
