I am using SQL 2000
I have a very lenght sql query with many select queries joined with UNION, like this:
--------------------------
select
Col1, Col2, COl3, Col4
form MyTable1
uion
select
Col1, null, Col2, Col3
from MyTable2
...
....
--------------------------
If I create stored procedures as follows:
Create procedures as sp1
select
Col1, Col2, COl3
form MyTable1
create procedures as sp2
select
Col1, Col2, COl3
form MyTable2
--------------------------
I would then like to do something like this
select * from
(exec sp1) as T1
union
select * from
(exec sp2) as T2
--------------------------
I tried the above and It doesn't work (syntax errors): Incorrect syntax near the keyword 'execute'.
Is it possible to use UNION when executing stored procedures?

no, you cannot use UNION with stored procedures.
but you CAN use UNION with stored functions, so if you can transform your procedures into functions, you can do this:
select * from dbo.Function1()
union all
select * from dbo.Function2()
note that you should use UNION ALL wherever possible, as UNION alone does a implicit DISTINCT on the returned rows, which first of all costs resources and is often giving confusion
now, if you are only doing a select from a table without any parameters, you will even better be off to use a view instead of procedures/functions.
create view view_1
as
begin
select * from table1
end
now, the function way would be:
create function function1()
returns table ( col1 int, col2 varchar(20) )
as
begin
return ( select field1, field2 from table1)
end
with a paramter:
create function function1( @param int )
returns table ( col1 int, col2 varchar(20) )
as
begin
return ( select field1, field2 from table1 where somefield = @param)
end
I have a stored procedure as written below;
CREATE PROCEDURE StaffnFamily
AS
SELECT EmployeeId, Name, DateOfBirth, RelationShip
FROM FamilyDetails union
( SELECT EmployeeId, Name, DateOfBirth, 'Self' AS "_'Self'_"
FROM Employees )
GO
But when i called it in my vb 60 program, it give me an error; "Invalid object name 'StaffnFamily'.
can this stored procedure be converted in view for me to use? if so how?
