More Selecting Into Local Variable With Dynamic Select...
May 25, 2004
Not wishing to derail the other recent thread on loading a local variable, I've posted this query (hee,hee,hee...I kill me) on a separate thread...though I think I am trying to do something similar...that is to build a dynamic select statement, but return a count of the rows it finds/doesn't find to a local variable...using the (amazingly timely) responses above, I tried this:
Note that the local variables @TargetDate and @TLevel are necessary because they are being passed into the procedure as variables....
DECLARE @SQLCmd varchar(256)
DECLARE @TargetDate smalldatetime
DECLARE @TLevel int
DECLARE @n int
SET @TargetDate = '2004-05-24'
SET @TLevel = 1
SET @SQLCmd = 'SELECT @n = count(*) FROM EventLog WHERE ((CONVERT(varchar(10), [Date], 101) = ''' +
CONVERT(varchar(10), @TargetDate, 101) + ''') AND (MsgLevel = ' +
CONVERT(varchar(3), @TLevel) + '))'
exec (@SQLCmd)
if @n > 0
print 'yep'
else print 'nope'
and, it's TRYING to work...but apparently the local variable @n is not recognized in the execution of the dynamic statement, as this is the output:
Server: Msg 137, Level 15, State 1, Line 1
Must declare the variable '@n'.
nope
Thoughts?

Hello all,
I'm a bit new to SQL Server and T-SQL (my background is in DB2), so hoping you can help me with this. I'm writing a T-SQL script that's hopefully going to scan a bunch of SQL server instances and record the results. We've got a mix of SQL2K and SQL2K5 instances, and for part of my script I only want to run something if the remote instance is SQL2K.
I'd tested this on my local PC with several instances created and it worked fine. When I try and run it for instances located on other servers it barfs :eek: . From what I've found from looking up the error message it looks like I've got myself a loopback -- but I don't know how to get around it - any ideas please?
DECLARE @tempdata TABLE (scratch sql_variant)
DECLARE @debug tinyint
DECLARE @server sysname
DECLARE @version varchar(20)
SET @debug=1
SET @server='SQLSERVER_INSTANCE'
INSERT INTO @tempdata (scratch) EXEC ('[' + @server + '].master.dbo.sp_executesql N''SELECT SERVERPROPERTY(''''ProductVersion'''')''')
SELECT @version = convert(varchar(100),scratch) from @tempdata
DELETE FROM @tempdata
IF @debug>0 BEGIN PRINT @server + ' is running SQL Server version: ' + @VERSION END
IF charindex('8.00',@version) > 0 BEGIN
PRINT 'SQL2K-only code goes here'
END
The error I get is:
OLE DB provider "SQLNCLI" for linked server "SQLSERVER_INSTANCE" returned message "The transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 1
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "SQLSERVER_INSTANCE" was unable to begin a distributed transaction.
I get this error running from a SQL2K5 instance against both SQL2K or SQL2K5
TIA, moff.

Hi:
Is there a way to assign a dynamic query result to a local variable?
declre @sqlString nvarchar(4000),
@minEventDate datetime,
@databaseName varchar(25)
selct @databaseName = 'customer_12345'
(actually, a cursor loop will assign the database name dynamically, here just to simplify the situation)
select @sqlString =
'select ' + @minEventDate + '= (select min(eventDate) from ' + @databaseName + '.dbo.tblABC)'
exec sql_executesql @sqlString
print '@minEventDate: ' + cast(@minEventDate as varchar(19))
Though the select min(eventDate) from customer_12345.dbo.tblABC
returns a date, ex. '02/01/2004 12:35 pm', however, the printed @minEventDate is always with Null value. It mean, the value was never correctly assigned to the local variable.
As an alternate way, I am using temp table to insert it with the query result and then assign to the local variable. Since I have many local variables to try to get the min, max, count for around 10 fields, perfer a way to direct assign to the local variable instead of 10 temp tables.
thanks

Hi all.
I am stuck in a bit of a conundrum for quite a while now, and I hope someone here will help me figure this one out.
So, first things first: let me explain what I need to do. I am
designing a web application that will allow users to consult info
available in a SQL2000 database. The user will enter the search
criterea, and hopefully the web page will show matching results.
The problem is the results shown aren't available per se in the DB, I
need to process the data a bit. I decided to do so on the SQL Server
side, though the use of cursors. So, when a user defines his search
criteria, I run a stored procedure that begins by building a dynamic
sql query and creating a cursor for it. I used a global cursor in order
to do so. It looked something like this:
SET @sqlQuery = ... (build the dinamic sql query)
SET @cursorQuery = 'DECLARE myCursor CURSOR GLOBAL FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
OPEN myCursor
FETCH NEXT FROM myCursor INTO ...
CLOSE myCursor
DEALLOCATE myCursor
This works fine, if there's only one instance of the
stored procedure running at a time. Should another user connect to the
site and run a search while someone's at it, it'll fail due to the
atempt to create a cursor with the same name.
My first thought was to make the cursor name unique, which led me to:
...
SET @cursorName = 'myCursor' + @uniqueUserID
SET @cursorQuery = 'DECLARE '+ @cursorName + 'CURSOR FAST_FORWARD FOR ' + @sqlQuery
EXEC @cursorQuery
...
The problem with this is that I can't do a FETCH NEXT FROM @cursorName since
@cursorName is a char variable holding the cursor name, and not a
cursor variable. So to enforce this unique name method the only option
I have is to keep creating dynamic sql queries and exucting them. And
this makes the sp a bitch to develop and maintain, and I'm guessing it
doesn't make it very performant.
So I moved on to my second idea: local cursor variables. The problem with
this is that if I create a local cursor variable by executing a dynamic
query, I can't extract it from the EXEC (or sp_executesql) context, as
it offers no output variable.
I guess my concrete questions are:
Is it possible to execute a dynamic sql query and extract a (cursor) variable from it?Is it possible to populate a local cursor variable with a global cursor, by providing the global cursor's name?Can I create a local cursor variable for a dynamic sql query? How?
Anybody sees another way arround this?Thanks in advance,
Carlos

Hi all
Imagine we have a table as follow:
Create Table Test(
Pkey int not Null identity Primary Key,
Name varchar(20) not null,
Famil varchar(30) not null
)
now is there anyway to Run following Script:
declare @FLDName varchar(10)
set @FLDName='Name'
Select @FLDName from Test
in the other hand is there anyway to use Local variables in a SELECT statements as above?
to tell you the truth , what really motivated me to do this , was being able to declare a User-Defined-Function and passing some fields as an String and then use them in a SELECT statement or any other T-Sql codes!!!
Could anyone help me.?
Kind Regards.

Hi,
I€™ve got the following statement :
SELECT TOP(1) Date, Status FROM TABLE1 WHERE TEC_STATUS = 1 ORDER BY DATE DESC
I want to retrieve the status field to a variable, but I€™m not being able to do so€¦ I think its due to the TOP function€¦
I have tried those with no success:
SELECT @var2 = TOP(1) [Date], @var = [ Status] FROM TABLE1 WHERE TEC_STATUS = 1 ORDER BY DATE DESC
SELECT @var2 = [TOP(1) Date], @var = [ Status] FROM TABLE1 WHERE TEC_STATUS = 1 ORDER BY DATE DESC
Is there Any way I can do that ?

Hi all,
I'm trying to be slick, but so far am just all wet *snicker*
I've got a table with rows that may or may not exist, and am trying to retrieve a column if an associate row DOES exist.
For argument's sake, my PIndex table looks like:
PID int
CreateDate smalldatetime
CloseID float
Here is my select logic that I thought would save an extra select to load my local variable if the row is actually in the table...
DECLARE @CloseID float
IF NOT EXISTS (SELECT @CloseID = CloseID
FROM PIndex
WHERE ((PID = '14') and
(CreateDate = '2004-02-06')))
SET @CloseID = 100
The SET afterwards is just to initialize the variable if it can't be had from an existing row in the table.
The trouble is, that it fails to compile with the following error:
>>>>> Line 3: Incorrect syntax near '='.
Any insights? My goal is to use a single select to load the value into my local variable if the associated row exists, or to set my local variable to 100 if it doesn't.
Thanks!

I am trying to figure out a way to retrieve a field value and assign it to a local variable with out destroying the whole structure of my T-SQL statement.
Here is the code:
DECLARE @AVERAGE_WHOLESALE_PRICE VARCHAR(20)
DECLARE @ORDERBY VARCHAR(20)
SELECT TOP 1 @AVERAGE_WHOLESALE_PRICE = P.NPT_PRICEX,
CASE NPT_TYPE
WHEN '07' THEN 1
WHEN '09' THEN 2
[Code] ....
The error message is
Msg 141, Level 15, State 1, Line 3
A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations.
How to modify this statement?

I've got an update statement with a subquery (I'll post the code further down) that I need to either make dynamic or do something else to make sure it does what I want.
The query is as follows:-
UPDATE dbo.tbl_Process_List_Control_Table
SET LastUpdateDateTime = (
SELECT ISNULL(MAX([LatestRowUpdateDateTime]), @LastUpdateDateTime)
FROM [wtbl_Process_List_Patient]
)
WHERE ProcessList = @ProcessName
This is a called proc with the following parameters:-
@LastUpdateDateTime is the date of the last record to be loaded
@ProcessName is the name of the process that was started/finished.
I need to make [wtbl_Process_List_Patient] dynamic so it looks at a different table based on a passed parameter.I've tried making the whole thing dynamic but it states I need to declare @LastUpdateDateTime which I can't see how to do as it's already passed to the proc (as is the process name).

Hello everybody,
Here I have two tables. Let's call them A and B.
A contains the folowing data: (address of persons)
PostCode Street Number CdeTour
-------- ------ ------ -------
31000 Well. 0025 NULL
31000 Well. 0050 NULL
31000 Wash. 0010 NULL
B contains the folowing data:
PostCode Street FirstEven LastEven FirstOdd LastOdd CdeTour
-------- ------ --------- -------- -------- ------- -------
31000 Well. 0002 0040 0043 0073 100
31000 Well. 0042 0084 0001 0041 200
31000 Wash. 0002 0050 0001 0049 100
* My problem is that I want to update the field A.CdeTour depending on the data present in B.
Let's take the first line from the table A: the number of the street 'well.' is '25', and '25' is odd and between '1' and '41' which meens that I should update my field A.CdeTour should be set to '100' (B.CdeTour).
Let's take another example, so in the second line: the street is still 'well.' but here the number is '50'. '50' is even and between '42' and '84' so the field A.CdeTour should be set to '200' (B.CdeTour).
Here I wrote a query, which doesn't work properly:
DECLARE @Num VARCHAR(4)
UPDATE A
SET @Num = Number, CodeTournee=
CASE WHEN @Num % 2 = 0 THEN(
-- even number of street
SELECT CdeTour
FROM B
WHERE @Num BETWEEN FirstEven AND LastEven
AND A.PostCode = B.PostCode
AND A.Street = B.Street
)ELSE(
-- odd number of street
SELECT CdeTour
FROM B
WHERE @Num BETWEEN FirstOdd AND LastOdd
AND A.PostCode = B.PostCode
AND A.Street = B.Street
)END
FROM A, B
The query runs but the problem is that it doesn't update the field, because it doesn't interpret @num by its value.
In fact, if instead of @num, I hard-code a value it works
... WHERE '0025' BETWEEN FirstOdd AND LastOdd ...
Can someone help me???? I would be very pleased, if someones could give me another way of doing it or a trick in order to avoid this problem.
Thanks in advance.

Hi guys I am sitting and testing som variants of this simple SP, and I have an question that I couldent answer with google or any thread in this forum.
Perhaps I am doing something really easy completly wrong here.
Why does the local variables in the first code segment slow down the overall execution of the procedure?
Dont mind the logic why I have them there are only testing som things out.
If i declare two variables the same way:
DECLARE @v INT
SET @v = 100
When I use it in a WHERE CLAUSE:
...WHERE [V] BETWEEN @v AND @x)
Is there any different then
...WHERE [V] BETWEEN 100 AND 200)
Cant figure this out, why does it hurt the performance so bad? As a C# guy its the same thing ?
Thanks in advance

Hi guys,
I have a cursor that loops over a table and I use a local variable to append the column data. However when I try to print this variable, it comes as empty!
The code is
declare @testVar varchar(max)
<cursor loop begins>
set @testVar = @testVar + ',' + @SomeColName
<cursor loop ends>
print 'Value: ' + @testVar
I can't understand why the @testVar is empty, since the @SomeColName has a value in every iteration.
Thanks!

Hi All,Sorry if the subject line is too obscure -- I couldn't think of a wayof describing this request.I have a table that contains approximately 1 million records.I want to be able to be able to select the top x records out of thistable matching variable criteria.Pseudo table records:custid, category, segment1,1,12,1,13,1,14,1,15,1,26,1,27,1,28,1,29,2,110,2,111,2,112,2,113,2,214,2,215,2,216,2,217,2,318,2,319,2,320,2,3So, what I'm trying to do is return a recordset, for example, thatcontains the top 2 of each variation of category and segment.ie:1,1,12,1,15,1,26,1,29,2,110,2,113,2,214,2,217,2,318,2,3The only way I can think to achieve this is in a while statement,performing individual selects against each combination, feeding thewhere criteria by variables that I automatically increment.I can't help thinking there's a much more graceful way of achievingthis?If anyone can give me any insight into this I'd be incrediblyappreciative!Many thanks in advance!Much warmth,Murray

I've created a stored procedure that converts an input string in richtext format (input as type TEXT) to plain text. I would like to be able to return this newly converted string, but I need to have some way of storing it in a local variable. My problem is that since I can't use the TEXT datatype as a local variable, I have no way of storing the large amounts of text I converted within the procedure. The VARCHAR(8000) just isn't large enough for my purposes. Anyone have any suggestions on how to go about doing this?

Is there a way to determine if a local variable exists or not?
There's a parameter I often use in code called @guid_batch that is usually declared in the parameter of a stored proc, but when in debugging it would be nice to have it available without having to change code.
Is there something that I could do similar to the following
Code:
IF VARIABLE_ID('@guid_batch') IS NULL
BEGIN
DECLARE @guid_batch UNIQUEIDENTIFIER
SELECT @guid_batch = NEWID()
END

DECLARE @Local_pNewLogonName varchar(60)
SET @Local_pNewLogonName = @pNewLogonName
SELECT * FROM .dbo.tblUser Where vcLogonName = @Local_pNewLogonName
and started getting this error on the web page.
ADODB.Recordset error '800a0cb3'
Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.
Does anyone know why this is happening? Nothing on the site has changed. If I change the sp back the errors go away. I'm trying to use local variables in all SP to avoid the slowness that can happen when using the parameter varibles.

hi,
i'm fairly new to visual studio and have a select statment which is displayed fine in my report, i have headings however of which one i'd like as a variable that i've declared and set
declare @MyVariable varchar(6)
set @MyVariable = "abcdef"
i know how to display a field in a cell like follows:
=Fields!Code.Value
or a parameter like follows:
=Parameters!month.Value
but how do i display my local variable called @MyVariable?
thanks in advance.. I've searched but can't find out how to do this and it's probably really obvious!!
