Capturing the results from exec command

Hi,

I'm writing a small query where I have a dynamic table name and dynamic condition for the criteria. In order to execute this, I need Exec command.

exec(select count(*) from @.dynamictable where condition = @.dynamiccond)

But here I want to capture the count from the select statement. Could any of you help me capture the results from exec command?

Thanks

USE pubs
GO

--sp_executesql
DECLARE @.chvTableName VARCHAR(100),
@.intTableCount INT,
@.chvSQL NVARCHAR(100)

SELECT @.chvTableName = 'Authors'
SELECT @.chvSQL = N'SELECT @.intTableCount = COUNT(*) FROM ' + @.chvTableName

EXEC sp_executesql @.chvSQL, N'@.intTableCount INT OUTPUT', @.intTableCount OUTPUT

SELECT @.intTableCount
GO

--EXEC (SQL)
DECLARE @.chvTableName VARCHAR(100),
@.intTableCount INT,
@.chvSQL NVARCHAR(100)

CREATE TABLE #temp (Totalcount INT)
SELECT @.chvTableName = 'Authors'
SELECT @.chvSQL = 'Insert into #temp Select Count(*) from ' + @.chvTableName

EXEC( @.chvSQL)

SELECT @.intTableCount = Totalcount from #temp

SELECT @.intTableCount

DROP TABLE #temp

Or:

DECLARE @.chvTableName VARCHAR(100)

CREATE TABLE #temp (Totalcount INT)
SELECT @.chvTableName = 'sysobjects'

insert into #temp(totalCount)
EXEC( 'Select Count(*) from ' + @.chvTableName)

SELECT * from #temp

DROP TABLE #temp

Note: it is generally considered a bad practice to do this sort of thing unless you are building some sort of tool. If this is a production application, it would be better to build a procedure per table:

create procedures count_accounts
as
select count(*) from account
go

Yes, it sounds like a lot of maintenance, but unless you build a large quantity of tables, it shouldn't be a big deal.

Capturing return status of EXEC(@String_Variable)

hello world how are thereWell that's certainly a lot of information to go on.

Care to elaborate?

Capturing exec or sp_executesql result

Hi.. perhaps it's stupid, but i am really a newbie..
How can i capture the result generated from exec('select ... ') or sp_executesql? such as

sp_executesql 'SELECT max(ID) FROM Yr' + year(getdate) + '.dbo.Sales' + month(getdate)

How can i get the 'max(ID)' data? I must get the data from sp_executesql or execute form.as far as I know the only way to capture the results from EXECUTE is to insert it into a temp table and then select out what you are looking for.|||You can set a variable from sp_executesql

declare @.id int, @.sql nvarchar(1000)
select @.sql = 'SELECT max(ID) FROM Yr' + year(getdate) + '.dbo.Sales' + month(getdate)

exec sp_executesql @.sql, N'@.id int output', @.id output|||oops

declare @.id int, @.sql nvarchar(1000)
select @.sql = 'SELECT @.id = max(ID) FROM Yr' + year(getdate) + '.dbo.Sales' + month(getdate)

exec sp_executesql @.sql, N'@.id int output', @.id output

Capture Returned Value From Exec(@Build) into another variable

I am building a SQL statement that returns a number.
when I execute the Built SQL statment EXEC(@.Build). What I need to do
now is take that number that comes back and store it in another
variable so I can do some conditional logic. Any ideas? See SQL below.

Something like @.Count=Exec(@.Build) which I know doesnt work.

Thanks,
Phil

DECLARE @.PullDate varchar(12)

Instead of EXEC(), you can use sp_executesql with an output parameter:

declare @.sql ntext, @.counter int
set @.sql = 'select @.counter = counter from openquery(...)'
exec sp_executesql @.sql, N'@.counter int', @.counter OUTPUT
select @.counter

See here for an example:

Simon|||I am able to get this to return a value but I cant get this to work.
Any ideas?

IF @.Counter>1
Print('Yes')
