Select Into Local Variable Within A IF NOT EXIST Test?
Feb 10, 2004
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.
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!!!
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
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
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.
I want to look at the size of the current database, so I can create a newone if it gets too big (we are working around the 2gb MSDE limit for ourcustomers).I would like to do something like this:DECLARE @size INTEGERexecute BLOB0000.dbo.sp_spaceusedand make @size = the database_size column value that sp_spaceused returns.Any way to do this?Thanks.
In my program i have function that will get one value from Database. Here i want to assign the output of the sql query to a local variable. Its like select emp_id into Num from emp where emp_roll=222; here NUM is local variable which was declared in my program. Is it correct.? can anyone please guide me..?
Do you know of some SQL that I can test a table to see if a column exists or not inside a stored procedure?
What I have is a table that contains data for a 10 year history. I asked at the time and was told at the beginning of every new year the table would create 2 new columns so I dynamically set up some of my stored procedure to provide for that….well as of Jan 22 they have not updated them so I have 2 options:
1) hard code the first year in there and change it when they tell us
2) test for the field if it is there start the countdown to grab the rest of the historic info….if not check for the next year until it finds the field in the DB.
I am trying to test a replication or at least get the feel for it on my local copy before I set it up on the real server.
Can I do that by setting my local database as the publisher as well as the subscriber?
I am getting an error message but I am wondering if there are any settings I can change to make this work. Or any other ideas of how to see the replication tool before actually doing it live?
Error message: "Server 'MyComputerName' is neither a Publisher nor a Distributor, or you do not have permission to access replication functionality on this server.
I might add that I am not only new to the project but also new to MS SQL Server.
I am in a situation where I need to get a copy of test database that ison production server running MSSQL 2000 Standard to my local machinerunning MSSQL 2000 personel. I tried to use the copy wizard where itappears I get connected to the source server OK but when I try toindicate the destination server which is my local machine I get errorspoping up about cannot connect to (local) etc.I am NOT a DBA just a programmer trying to get a local test environmentup to be more productive.Lsumnler
1) Need a simple routine or system function for testing for or verifying the existence of a file or folder on the local server's file system. Returning a simple boolean value or 1 or 0 would be fine.
2) Need a syntax and use description of the new "master.dbo.xp_create_subdir" function ... anyone have some documentation or links? MS technet and MSDN have nothing.
I need to only receive files via ftp when the file does not exist on my local machine. FIles are being added to the remote location on a weekly basis and they are being downloaded locally. I do not want to download all the files each time. Instead, just download what was not already downloaded. Is there a way to do this? I want to do this using SSIS / ftp task.
Are global variable parameters in a DTS package specific to "only" that one package and do not effect other packages?
I need to add a variable to a test package but am worried that if I add this parameter it might affect the live production Table. There are two different servers on different sides of the firewall, there are two different databases and there are two tables but with different names, and there are DTS packages but they reference different tables in the query code.
So is it ok to add the global variable which would allow this DTS to delete recent records from the "test" version and it wont do anything to my live version?
I have a variable scoped to the package named "Filecount". When I try to reference it in a precedence constraint expression (@Filecount > 0) I get "The variable 'Filecount' was not found in the variables collection. The variable might not exist in the current scope."
I am trying to create a procedure or function that will deal with weekly information for staff records.
Rather than declaring 14 local variables for the information, is it possible to declare a local variable as an array? Sorry for using VB terminology - not sure how SQL would describe it.
* 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.
Set @Test='SELECT VIOXX_LastName + '' + VIOXX_FirstName + '' + CONVERT(varchar(50), VIOXX_Number) AS PlaintiffsName, VIOXX_Number FROM tblPlaintiff WHERE VIOXX_Number NOT IN(SELECT VIOXX_Number FROM tblCase_Plaintiff) OR VIOXX_Number IN (SELECT tblCase_Plaintiff.VIOXX_Number FROM tblCase INNER JOIN tblCase_Plaintiff ON tblCase.Case_Number = tblCase_Plaintiff.Case_Number WHERE (tblCase.Status = ''InActive'')) ORDER BY VIOXX_Number, VIOXX_LastName' Select @Test
and get the following result: SELECT VIOXX_LastName + ' + VIOXX_FirstName + ' + CONVERT(varchar(50), VIOXX_Number) AS PlaintiffsName, VIOXX_Number FROM tblPlaintiff WHERE VIOXX_Number NOT IN(SELECT VIOXX_Number FROM tblCase_Plaintiff) OR VIOXX_Number IN (SELECT
the latter part of my original text is not stored in the variable. Is there some limitation on the number of characters for a local variable in transact sql?
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 /Johan

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!
Is there an expression syntax for putting a local variable value into a text box like there is for putting a parameter value? I'm using the report builder via VS
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?
I'm trying to have an identity column seed value specified with a local variable value as follows, however it doesn't allow me to do it (Says cannot use a variable name for a seed value). Any ideas or suggestions?
DECLARE @idvalue int
SELECT @idvalue = max(accountid) + 1 FROM account
CREATE TABLE accounttemp (Accountid int IDENTITY(@idvalue,1), name char(10), address char(10))
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

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.
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!!
The test.sql scripts I write to test CLR stored procedures run successfully, but when I want to display the resulting data in the database with a simple "SELECT * from Employee"
I get the result as: Name Address ---- ------- No rows affected. (1 row(s) returned)
But not the actual row is displayed whereas I would expect to see something like:
Name Address
---- -------
John Doe
No rows affected.
(1 row(s) returned)
I have another database project where doing the same thing displays the row information but there doesn't seem to be a lot different between the two.
Can someone show how to do this?I have a SqlDataSource1, and i have a SELECT * FROM Table1How would i get@ProdName@ProdNumber Into the following local variablesString ProductNameInt ProductNumber I’m using C# and ASP 2.0 VWDThanks for Help1
In a stored proc, can you declare a local variable that is an existing column in a table & then based on other criteria, do an order by using the local variable?
