Sp_executesql Bug? - @@error = 0 When @statement Is Null
Aug 22, 2007
Example code:
declare @somesql nvarchar(20)
execute sp_executesql @somesql, N'@lnCurrRow int', @lnCurrRow = 1
PRINT @@ERROR
@@Error returns 0, which is seems incorrect since @somesql is null. If you substitute @somesql for the constant NULL then an error is fired. The above also executes successfully with @@error = 0 if you set @somesql = '' (empty string).
EXEC behaves the same way.
It makes sense that executing an empty string should be fine, but NULL? Is there a SET option available that will cause an error to be raised if sp_executesql attempts to execute a nvarchar variable that's set to NULL?
Thanks.

I am using dynamica SQL in one of my stored procs That performs BULKINSERT
on few tables.
If there is a PK constraint violation, I wanted to write an error routine.
But once SP_EXECUTESQL gives an error, the stored proc just abends
not allowing me to ado anything else.
Can anyone help me with some information on how to perform error
handling when I am using Dynamic SQL?
I am also sending the the piece of code and the error message.
CODE: Assume that all variables are declared appropriately.
SET @string = 'BULK INSERT Tb_Manfg ' + char(13) +
'FROM '+ '''' + @path_tb_manfg + '''' + char(13) +
'WITH (FIELDTERMINATOR = ' + '''' + '|=|'+ '''' + ',' + char(13) +
'ROWTERMINATOR = ' + '''' + '
' + '''' + ')'
IF @error = 0
BEGIN
PRINT 'NOW Tb_Manfg GOING TO BE INSERTED.......'
EXEC SP_EXECUTESQL @string
/*
This is where the stored proce abends.
The subsequent code is not executed at all.
*/
PRINT 'ERROR IS.........'
PRINT @@ERROR
IF @@ERROR = 2627
BEGIN
PRINT 'AN ERROR OCCURED WHILE INSERTING INTO Tb_Cateory'
SET @error = @@ERROR
return
END
ELSE
BEGIN
SET @error = @@ERROR
END
ERROR MESSAGE:
Server: Msg 2627, Level 14, State 1, Line 1
Violation of PRIMARY KEY constraint 'PK__TB_Manfg__1FCDBCEB'. Cannot insert duplicate key in object 'TB_Manfg'.
The statement has been terminated.
Thanks a lot.

Hi,
I need to capture the error code while using sp_executesql
insert into #temp1
exec @status=sp_executesql @actn_id1
This @actn_id1 contains the proc name and the parameters. The problem now is when I get an error it’s not captured in the @status column, it always 0 and also tried @@error and was also 0.
Server: Msg 55118, Level 16, State 1, Procedure S_START_LUW, Line 383
info_upd_id =530129179546!, is using current subj_id.
This is a user defined error captured using raiserror inside a sub proc.
Can I capture this error number in the status column?
Thanks in advance for the help

Hey all,
Having some trouble with a Database email system I created. The system consists of two tables, DATA_ELEMENT and EMAIL_MESSAGE. So the email message body and recipient fields may contain substitution macros such as {![CUST_EMAIL]!}. The CUST_EMAIL data element row then stores the SELECT, FROM and WHERE clauses separately. There is a stored proc to search the message body and recipients for these substitution macros and replace them with the appropriate values from the DB.
The system is working well except I have one particular substitution macro called VENUE_NAME_BY_PPPID which is causing a problem.
Quote: Server: Msg 207, Level 16, State 3, Line 3
Invalid column name 'PARTNER_PRODUCT_PRIZE_ID'.
And here's the query which is creates this error (without the escaped single quotes):
Code:
SELECT P.PARTNER_NAME + ISNULL(' - ' + PS.SITE_NAME, '')
FROM PARTNER_PRODUCT_PRIZE PPP
JOIN PARTNER_PRIZE PP ON PP.PARTNER_PRIZE_ID = PPP.PARTNER_PRIZE_ID
JOIN PARTNER P ON P.PARTNER_ID = PP.PARTNER_ID
LEFT JOIN PARTNER_SITE PS ON PS.PARTNER_ID = PP.PARTNER_ID
AND PS.PARTNER_SITE_ID = PP.PARTNER_SITE_ID
WHERE PPP.PARTNER_PRODUCT_PRIZE_ID = '19'
And just after this print statement, the query is executed with sp_executesql()
Any advice is greatly appreciated as this query runs fine when I execute from the query window. However, if I escape all the necessary quotes, I can't get it to run when I put the string inside of sp_executesql().

Hi
I've got an SSIS package, I'm in a Data Flow step that has a OLE DB Command Data Flow Transformation.
The SQLCommand in the OLD DB Command is:
______________________
UPDATE Employment_Episode_Dim
SET Commence_Serv_Date = ?
WHERE AGS_Number = ?
______________________
The package will run through successfully, but I don't see any updates
in Employment_Episode_Dim. I ran a trace, and this is a sample of the
SQL that is being executed:
______________________
exec sp_executesql N'UPDATE EMPLOYMENT_EPISODE_DIM
SET COMMENCE_SERV_DATE = @P1
WHERE (AGS_NUMBER = @P2)',N'@P1 datetime,@P2 int',''2005-01-27
00:00:00:000'',78577229
______________________
If I take that SQL and execute it in a query window, it fails due to
two single quotation marks placed around the date parameter being used
as @P1.
Why does SQL/SSIS put two singles around the date? It's outside of the
string to be executed, so it doesn't seem to need to have the double.
Can anyone please help?
Thanks

This is a odd problem where a bad plan was chosen again and again, butthen not.Using the profiler, I identified an application-issued statement thatperformed poorly. It took this form:exec sp_executesql N'SELECT col1, col2 FROM t1 WHERE (t2= @Parm1)',N'@Parm1 int', @Parm1 = 8609t2 is a foreign key column, and is indexed.I took the statement into query analyzer and executed it there. Thequery plan showed that it was doing a scan of the primary key index,which is clustered. That's a bad choice.I then fiddled with it to see what would result in a good plan.1) I changed it to hard code the query value (but with the parmdefinition still in place. )It performed well, using the correct index.Here's how it looked.exec sp_executesql N'SELECT cbord.cbo1013p_AZItemElement.AZEl_Intid AS[Oid], cbord.cbo1013p_AZItemElement.incomplete_flag AS [IsIncomplete],cbord.cbo1013p_AZItemElement.traceflag AS [IsTraceAmount],cbord.cbo1013p_AZItemElement.standardqty AS [StandardAmount],cbord.cbo1013p_AZItemElement.Uitem_intid AS [NutritionItemOid],cbord.cbo1013p_AZItemElement.AZeldef_intid AS [AnalysisElementOid] FROMcbord.cbo1013p_AZItemElement WHERE (Uitem_intid= 8609)', N'@Parm1 int',@Parm1 = 8609After doing this, re-executing the original form still gave badresults.2) I restored the use of the parm, but removed the 'exec' from thestart.It performed well.After that (surprise!) it also performed well in the original form.What's going on here?

Hi,
Our report is working fine with data loaded from a stored procedure (#1) that contains a fairly simple Select statement. We need the same report to work with a dataset loaded from a stored procedure (#2) that uses 'Exec sp_executesql @queryString'. Unfortunately, attempts to call the latter cause an error in the report. From everything that I've read, there should be no difference between datasets created using either method. Any ideas what could be getting in the way of the latter?
I have doublechecked that the dynamic query is returning a valid dataset and that all the columns are in the same format as sp #1. The designer shows the dataset and the report with the data loaded, but the live system produces an error.
Any help is much appreciated.

I searched through the forums thinking this may have been brought up before, but I cannot find a post the directs to my problem.
I have a lookup table (lookup.os) which defines various operating systems. It has a "OSID" field which is just a primary key numbering, a "OSInstr" field which is used in a 'like statement' in a cursor used later on and "OSName" which is the full name of the OS.
ID| BROWSERNAME | INSTR
*********************************
1 | Windows XP | Windows+NT+5.1
2 | Windows 2003 | Windows+NT+5.2
3 | Windows Vists | Windows+NT+6.0
.....
19 | Unknown Operating System | <blank>
I have a cursor loop that goes through another table (tblIISLog_ALL_OS) and searches through the instr of the (lookup.os) table to add to a stats of a third table (statistics.os). It works fine going through the loop, except there is a problem with the last value in the (lookup.os) table. If the value does not match the rest, it will select value "19 - Unknown Operating System" which is correct, but if the value is null it will not be selected. I take it 'NULL' >< a blank like statement. Here is what I have now. I am open to suggestions of what I should do. I was thinking maybe removing the "19 - Unknown Operating System" from the (lookup.os) table and after the first cursor loop has run, run it again and everything remaining it will just put in as "19 - Unknown Operating System". What do you think?
DECLARE @TempID int,
@TempOSInStr varchar(50),
@TempOSName varchar(100),
@TempCount int
DECLARE loopc CURSOR FOR
SELECT [OSID],
[OSInStr],
[OSName]
FROM [IISLOG_REPORTS].[dbo].[lookup.os]
OPEN loopc
FETCH NEXT FROM loopc INTO @TempID,
@TempOSInStr,
@TempOSName
SET @TempID = 0
SET @TempCount = 0
WHILE @@fetch_status = 0
BEGIN
---------------------
SELECT [date], @TempOSName, count(1)
FROM [IISLOG_REPORTS].[dbo].[tblIISLog_ALL_OS]
WHERE '%' + [csUserAgent] + '%' like '%' + @TempOSInStr + '%'
GROUP BY [date]
INSERT INTO [IISLOG_REPORTS].[statistics].[os]
([TotalDate]
,[OSID]
,[OSTotal])
SELECT [date], @TempID, count(1)
FROM [IISLOG_REPORTS].[dbo].[tblIISLog_ALL_OS]
WHERE '%' + [csUserAgent] + '%' like '%' + @TempOSInStr + '%'
GROUP BY [date]
DELETE FROM [IISLOG_REPORTS].[dbo].[tblIISLog_ALL_OS]
WHERE '%' + [csUserAgent] + '%' like '%' + @TempOSInStr + '%'
----------------------
FETCH NEXT FROM loopc INTO @TempID,
@TempOSInStr,
@TempOSName
---------------------
END
CLOSE loopc
DEALLOCATE loopc
Thanks for the assistance. I hope I provided all the necessary information and explained it ok.

Hello,I have a table which contains some nullable columns. I want to write asingle query, which can be prepared (ie. prepared statement), that canhandle null or non-null values for the where clause. Is this possiblein a standard-conforming manner?The simple for of the query is this:SELECT * FROM <table> WHERE <column> = <value>But when the value to be matched on is NULL, the syntax of the querymust change to be:SELECT * FROM <table> WHERE <column> IS <value>In the second case <value> is NULL.I know one option might be to change the ANSI NULL handling option,but I am loathe to do this (I have five RDBMS's to support, not justMSSSQL).I thought I might have been able to cheat using an IN clause to makethe SQL consistent, but no luck.ThanksKevin

Hi.
I have an sql table which contains a number and a name. I would like to create a select statement that will display these two fields in the format :
"number | name", but if there is a null value in the number it will display only the name and vice versa.
How can I do it ?

Code below:
SELECT
NAME,
CASE WHEN PHONE IS NULL THEN '-' ELSE PHONE END AS PHONE
FROM
PATIENT
WHERE PHONE = '-'
If I am switching the NULL values to hyphens (-), why am I not getting any records when I look for hyphens in the WHERE clause? The script is not as simple as this or else I would just check for NULL values. I really need to switch NULL values to something I can pass on to a variable and query on it from Reporting Services.

On my aspx page I have a basic sqldatasource and gridview - both were set up using the wizards. The SQL Server 2000 database table that the sqldatasource is querying has some fields in it that are set to not allow nulls, however, the gridview control is not displaying all of the fields in the table - including some of the non-null fields.
My problem is, when I run an insert on the table from my aspx page, I get an error that says: "Cannot insert the value NULL into column 'ColumnName', table 'TableName'; column does not allow nulls. INSERT fails. The statement has been terminated."
The 'ColumnName', as you may have guessed, is one of the aforementioned columns that doesn't allow nulls, but isn't in the GridView.
How can I do an insert on this table without messing with the non-null fields. Those fields are relevant to the purposes of the gridview, so I don't want to display them, let alone allow editing of them.
Any suggestions on my options would be greatly appreciated!
Thanks

I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?
Code:
CREATE TABLE #sales(
OrdNo int,
StatusGrp varchar(10),
Demand decimal(10,2)
)
INSERT INTO #sales
VALUES (1,'Ship',100.00)

I am working on a Function that takes multiple parameters. I have a query that populates a temporary table, and then it processes some logic. My question is, if the parameter is passed as null, I dont want the query to be affected by this null value. Rather, I would like to not pass it at all to the query. So if the parameter is NULL, dont pass it through the query. I have the following but its not compiling right:
SELECT bom.pEngr_BOM_ID , bom.fEngr_Item_ID, det.pEngr_BOM_Detail_ID, 1, bom.Bill_Type, bom.Rev_Ltr, bom.Series_Ltr
FROM dbo.Engr_BOM_Control bom WITH (nolock)

ON det.fEngr_BOM_ID=bom.pEngr_BOM_ID
WHERE bom.pEngr_BOM_ID=@v_pEngr_BOM_ID
AND det.fEngr_BOM_ID=@v_pEngr_BOM_ID
CASE WHEN @v_Bill_Type IS NOT NULL THEN

If I try to run the code below, and even one of the values in the INNER

What I need is to see the results even if one or more of INNER JOIN

I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID
OR
Student.GradeLevel <> esis.GradeLevel
OR
Student.LegalName <> esis.LegalName
OR
Student.WithdrawDate <> esis.WithdrawDate
Student.SPEDFlag <> esis.SPEDFlag
OR
Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid,
.....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

The below code returns a NULL for all the Differential backups. I am trying to return the word Differential when there is a NULL because I can tell from when the NULLs occur that those are my differential backups. How can I get the result I want?
SELECT
CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,
msdb.dbo.backupset.database_name,
msdb.dbo.backupset.backup_start_date,
msdb.dbo.backupset.backup_finish_date,
CASE
WHEN msdb..backupset.type = 'D' THEN 'Database'
[Code] .....

I have built a SSIS package that bascially updates two columns in table A...the update statement reads;
update Table A
set Colum 1 = ?,('?' is a variable)
Column 2 = ?
In my SSIS package, I would like to be notified/capture, if one or both variables are null....How do I do that ?..error log ?
The package runs fine both ways (if variables are null or not)
Thank you

If I run this statement in Query Analyzer, it properly returns 1for my testing table. But if I put the statement into a storedprocedure, the stored procedure returns NULL. What am I doingwrong? I suspect it may be related to how I defined the parametersfor the stored procedure. Perhaps my definition of TableName andColumnName don't match what COLUMNPROPERTY and OBJECT_ID expect toreceive, but I don't know where to look for the function declarationsfor those. Any pointers would be appreciated.Select statement:SELECT COLUMNPROPERTY(OBJECT_ID('Table1'), 'TestID', 'IsIdentity') ASIsIdentityTable definition:CREATE TABLE [dbo].[Table1] ([TestID] [numeric](18, 0) IDENTITY (1, 1) NOT NULL ,[Description] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL) ON [PRIMARY]Stored Procedure definition:CREATE PROCEDURE spTest(@TableName varchar,@ColumnName varchar)AS SELECT COLUMNPROPERTY(OBJECT_ID(@TableName), @ColumnName,'IsIdentity') AS IsIdentity

The following is a simplified version of my SQL statement. I am attempting to do a simple count(*) with two groupings and a where clause. This is Select command for a GridView. However, I am unable to display zeros. The rows are completely missing and I would greatly appreciate someone's help. I have already tried Group By All, but that, unfortunately, does not work. Here is my SQL statement:
"SELECT [GENDER], [RACE], COUNT(*) FROM [TABLE] WHERE ([COLUMNNAME] ='SOMETHING') GROUP BY [GENDER], [RACE]"
Thanks for the help in advance!

I wrote a select statement, I only want to see orders with max lastUpdatedOn date of 14 days and older. Now my results show dates with all orders of 14 days and older (which is OK), but all others are displayed in the "Uitgifte" column as "NULL". But those orders should not be displayed at all.
selectdistinct ProductionHeader.ProdHeaderOrdNr,
ProductionHeader.PartCode,
ProductionHeader.Description,
ProductionHeader.Qty,
(select max (ProdStatusLog.ProdStatusCode)
[code]...

I have table Products and Orders that has the following columns:
table Products: ProductID, ProductName
table Orders: OrderID, ProductID, OrderDate, Quantity, Price
The Orders table contains orders placed on all the dates. I want to obtain a list of orders for a particular date, if there is no order for a product on the requested date, I want to return null values for the Quantity and Price fields.
I tried the following select statement:
select Products.ProductName, Orders.Quantity, Orders.Price from Products left join Orders on Products.ProductID = Orders.ProductID where Orders.OrderDate = '10/16/2004'
Where, there are a total of three products (A,B,C) in table Products. Product-C has no order on 10/16/2004, but I want it to return :
ProductName / Quantity / Price
Product-A 5 1.89
Product-B 6 2.43
Product-C null null
Obviously, my sql statement won't work becaue the where clause will filter out Product-C.
Could anyone help me figure out how to modify my sql code to get the resultset I want?
Thanks in advance.
