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..?
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 have a derive column( sequence) transformation in data flow , i am trying to assign this column to a variable , so that i can use it in the SQLtask control flow... how can i do this? can you show me some examples?

Hi
I want to use a variable in a number of SQL statements as paramenter. But I am not sure how to assign the value I want to the variable. The value I want is the maximum week number from one of my tables. I know how to put this value into a new table (which is one field and One row), but I cannot see how to pass this value to my variable. Using the table in my SQL is not straight forward unfortunately, at least not for me.
Hi this is probably a very stupid question, but I still need to know.
How do I set the result of a 'SELECT' statement to a variable? I know I can use CURSOR, but I am certain the SELECT statement will return either 1 record or NULL. Can I use something else apart from CURSOR?
I wish to dynamically assign Select Statement to SqlDataSource. Anyone has any idea?? Is it possiable at all?

Hello, I'm needing to pass a variable length number of values to a select statement so I can populate a result list with items related to all the checkboxlist items that were selected by the user. for example, the user checks products x, y and z, then hits submit, and then they see a list of all the tests they need to run for each product. I found a UDF that parses a comma delimited string and puts the values into a table. I learned how to do this here: http://codebetter.com/blogs/darrell.norton/archive/2003/07/01/361.aspx I have a checkboxlist that I'm generating the string from, so the string could look like this: "1,3,4,5,7" etc.I added the function mentioned in the URL above to my database, and if I understand right, I should be able to pass the table it creates into the select statement like so:
WHERE (OrderStatus IN ((select value from dbo.fn_Split(@StatusList,','))) OR @StatusList IS NULL) but now I don't know how to assign the string value to the parameter, say to '@solution_id'.my current select statement which was generated by Visual Studio 2005 looks like this: SELECT [test], [owner], [date] FROM [test_table] WHERE ([solution_ID] = @solution_ID) ...but this only pulls results for the first item checked in the checkboxlist.Does anyone know how this is done? I'm sure it's simple, but I'm new to ASP .NET so any help would be greatly appreciated.
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 ?
Thanks
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!

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?
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.

I am trying to set a vaiable from a select statement
DECLARE @VALUE_KEEP NVARCHAR(120),
@COLUMN_NAME NVARCHAR(120)
SET @COLUMN_NAME = (SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'CONTACTS' AND COLUMN_NAME = 'FIRSTNAME')
SET @VALUE_KEEP = (SELECT @COLUMN_NAME FROM CONTACTS WHERE CONTACT_ID = 3)
PRINT @VALUE_KEEP
PRINT @COLUMN_NAME
RESULTS
-------------------------------------------------------------------------------------------
FirstName <-----------@VALUE_KEEP
FirstName <-----------@COLUMN_NAME
SELECT @COLUMN_NAME FROM CONTACTS returns: FirstName
SELECT FirstName from Contacts returns: Brent
How do I make this select statement work using the @COLUMN_NAME variable?
Any help greatly appreciated!
I have a user login scenario where I would like to make sure that they not only exist in the user table, but also make sure there account is "verified" and "active". I'm trying to return 3 output parameters. UserID, verified, active. Is this possible?
Do I need just a select statement to do this? What is the difference between the output and select statements?
Thanks in advance.
I'm executing the following...
select COL1, min(COL2) from TABLE group by COL1
the table has many duplicate entries, where COL2 is the primary key and unique, but its the duplicate COL1 entries that have to be removed.
I was hoping a simple
"delete from table where COL1 not in (select COL1, min(COL2) from TABLE group by COL1)"
would do the trick, but obviously in returning two columns from the subselect this won't work. Can I hide the COL2 output from the query that will be put in the subselect?
this is a one-off thing, so i'm not overly concerned about overhead or elegance. just need to make it so.

There are about 10 select statements in a store procedure.
All select statements are need.
Is it possible to output only the result of last select statement?
Is there anyway to use a variable to define a column in a select statement. I can put the variable in but I'm sure it will be read as a literal instead of the column.
select @column_name from table
Is there a way to build a select statement that will output related rows with different column data per row? I want to return something like:
rowtype| ID | value
A | 123 | alpha
B | 123 | beta
C | 123 | delta
A | 124 | some val
B | 124 | some val 2
C | 124 | some val 3
etc...
where for each ID, I have 3 rows that are associated with it and with different corresponding values.
I'm thinking that I will have to build a temp table/cursor that will get all the ID data and then loop through it to insert each rowtype data into another temp table.
i.e. each ID iteration will do something like:
insert into #someTempTable (rowtype, ID, value) values ('A', 123, 'alpha')
insert into #someTempTable (rowtype, ID, value) values ('B', 123, 'beta')
insert into #someTempTable (rowtype, ID, value) values ('C', 123, 'delta')
etc..
After my loop, I will just do a select * from #someTempTable
Is there a better, more elegant way instead of using two temp tables? I am using MSSQL 2005

I'm trying to add a 'change password' control to my site and seem to be having some issues.

'System.Security.Principal' does not match with a table name or alias name used

I have a table 'table_list' which contains two columns, table_name and a record_count. This table stores a list of tables and their corresponding record counts.
What I am trying to do is, to be able to write a select statement, that can read each table name in the 'table_name' column, execute a select count(*) for the same, and update its record_count with the result of select count(*).
This is the code in my procedure..
DECLARE @tab_list CURSOR
set @tab_list = CURSOR FOR select * from table_list
OPEN @tab_list
DECLARE @tab_name varchar(256)
DECLARE @rec_cnt int
FETCH NEXT FROM @tab_list INTO @tab_name, @rec_cnt
select count(*) from @tab_name
This select is looping around along with FETCH till all the table names are exhausted and their counts are updated from the cursor back into the table.
Problem is that, I am not able to use select count(*) from @tab_name, and its not accepting a variable there.
Please help me to construct the select statement that is similiar to
x=<table name>
select * from x
where x is a variable and the table name gets substituted.
what is the syntax for it ?

I know I'm doing something wrong with the data type because it's stores the whole select statement as a string

hey all,
I have the following query:
ALTER PROCEDURE [dbo].[sp_SelectMostRecentArticle]
AS
BEGIN
DECLARE @article_id INT
SELECT @article_id = (
SELECT TOP 1 article_id
FROM article
ORDER BY article_id DESC
)
DECLARE @comment_count INT
SELECT @comment_count = (
SELECT COUNT(comment_id)
FROM comment
JOIN article ON article_id = comment_article_id
GROUP BY article_id
HAVING article_id = @article_id
)
SELECT TOP 1 article_id, article_author_id,
article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_id
article_author_ip, author_display_name,
category_id, category_name--, comment_count AS @comment_count
FROM article
JOIN author ON author_id = article_author_id
JOIN category ON category_id = article_category_id
GROUP BY article_id, article_title, article_body, article_post_date,
article_edit_date, article_status, article_author_ip,article_author_id,
author_display_name, category_id, category_name
HAVING article_id = @article_id
END
GO
as you can see, im trying to return a comment_count value, but the only way I can do this is by defining the variable.
I have had to do it this way, because I cannot say COUNT(comment.comment_id) AS comment_count or it returns an error that it cant reference the comment.comment_id.
But when change it to FROM article, comment; I get errors about the article_author_id and article_comment_id.
And i cant add a join, because it would return the amount of rows of the comment...
unless someone could help with what i Just decribed (as i would prefer to do it this way), how would i return the variable value as part of the select statement?
Cheers
