execute sql returned in sql query

I have a query that runs against a sql server database that produces a sql statement for each row of the query returned.

EG.

DROP PROCEDURE dbo.[Proc1]
DROP PROCEDURE dbo.[Proc2]

etc

In the same script, how can I execute the sql returned in the 开发者_C百科query?

Check out sp_executesql

One way is, you'll have to iterate through your result set and use sp_executesql. Just curious though, what are you trying to accomplish

Dump the results into a variable of type varchar(max) or nvarchar(max) and then EXEC them

-- Create a terrible, horrible cursor to run the statements
-- You have just now killed a kitten
DECLARE Csr cursor for
SELECT
    P.name AS proc_name
,   schema_name(P.schema_id) AS schemaname
FROM
    sys.procedures P


DECLARE @query varchar(max), @proc_name sysname, @schema sysname

OPEN Csr
FETCH NEXT FROM Csr INTO
    @proc_name, @schema

WHILE (@@fetch_status <> -1)
BEGIN
    IF (@@fetch_status <> -2)
    BEGIN
        BEGIN TRY
            -- build out the drop statement, may not be necc
            SET @query = 'DROP PROCEDURE' + QUOTENAME(@schema) + '.' + QUOTENAME(@proc_name)
            -- Actually run the dynamic query
            EXECUTE(@query)
        END TRY
        BEGIN CATCH
            -- Be good and note what failed, fix this manually
            PRINT 'This query failed'
            PRINT @query
        END CATCH
        FETCH NEXT FROM Csr INTO
            @proc_name, @schema
    END
END

CLOSE Csr
DEALLOCATE Csr

What you need to do is have your query output into a variable. If you are using a stored procedure, then specify an output paramater of varchar. Then when you call the stored procedure to generate the SQL query just pass that varchar variable to sp_executesql.
