execute sp in a select statement

Question

For an instance I a select statement and it is returning 1000 rows. I need to execute a particular stored procedure for every row the the select statement is returning.

have you got any idea how can I do that?

Answer 1

Construct the EXECUTE statements in your select like this:

SELECT 'EXEC sp_whatever ' + parameter stuff
FROM   your_table

Then run the results! Alternatively, paste your results into a spreadsheet package, and use string concatenation to construct the EXEC statements - just create a formula and paste it down the 1,000 rows. I personally prefer the first approach.

I am reading your "for an instance" as "this is a one-off task". If this is a task that needs automating, then one of the other answers may be the right approach.

Answer 2

Disclaimer: I'm not sure if I understand your question correctly.

Assuming you are on SQL Server 2005 upwards, you could create a table-valued user defined function and use the OUTER APPLY operator in your query.

Answer 3

Use a User Defined Function?

Most RDBMS will let you select rows from stored procedure result sets. Just put your stored procedures in the FROM clause, as you would for common table expressions. For instance:

SELECT sp.ColumnInResultSet, t.BaseTableColumnName
FROM sp_whatever ( Args) sp INNER JOIN BaseTable t ON t.ID = sp.ID;
