I have another stored proc2 which returns table with other data..storedproc2 has date parameters @datefrom and @dateto.

Now, i need to assign storedproc1 to @datefrom in storedproc2

Is it possible to assign

Answer 1

Not, it’s not possible the way you wished.

Here’s interesting article on how to share data between stored procedures

How to Share Data between Stored Procedures

In my opinion, the simplest way is to use output parameter or temp table. For more info check the link. Here’s a simple way of using output parameter.

DECLARE @datefrom smalldatetime

Exec storedproc1 @datefrom OUTPUT 

Exec storedproc2 @datefrom

Here’s another simple example of using temp table for getting result set from a stored procedure

DECLARE @datefrom smalldatetime

CREATE TABLE #tmp (dateFrom smalldatetime)

INSERT #tmp
EXEC storedproc1

SELECT TOP 1 @datefrom = dateFrom FROM #tmp 

Exec storedproc2 @datefrom

You could also use shared temp table. You will find implementation in article I’ve provided.

Good Luck!
