How can I return a list of values from a stored procedure?
Well I am calling a stored procedu开发者_开发百科re from another stored procedure and I need it to return something like an array.How can I do it?
May I suggest that you take a look at Sommarskogs homepage on Arrays and Lists in SQL Server?
His homepage is full of information, so set aside a few hours to read everything. But start of with this link. It is only about 60 screens full ;-)
IMHO it covers everything on passing info between stored procedures. Highly recommended. And you really only need to read the first few pages.
You can do this with a temporary table or actual table. Note that (unfortuantely) it doesn't work with table variables.
Set up your table:
CREATE TABLE #Foo (Bar NVARCHAR(50), BAZ INT)
Then your stored procedure:
CREATE PROCEDURE [GetFoo] AS
BEGIN
SELECT [BarCol], [BazCol] FROM [BarBazSource]
END
Then use the EXEC
T-SQL command:
INSERT #Foo EXEC [GetFoo]
Your #Foo
temporary table now contains the output of the [GetFoo]
stored procedure.
For more information there's an MSDN article here: "Getting Creative with EXEC and EXEC()"
