Stored procedure calling another stored procedure_

Hi all,

I have a stored procedure that return a resultset
e.g. stored proc: get_employee_de tails
select emp_id, emp_name, emp_salary, emp_position
from empoloyee

I would like to write another stored procedure that executes the above
stored procedure - returning the same number of records but it will
only show 2 columns
e.g. new stored proc: get_employee_pa y -- executes
get_employee_de tails
I only need to know emp_id, emp_salary.

How can this be done in sql stored procedure?

Thanks,
June Moore.

June,

I would make the first stored proc a UDF (user defined function) that
returns a table. This allows the second stored proc to use the UDF in the
From clause as if it were a table. You can then extract just the fields you
need in the Select statement. For example:

The second stored proc would contain the following SQL:

Select emp_id, emp_salary
From get_employee_de tails (assumes get_employee_de tails is a Table-Values
UDF)

See "Rewriting Stored Procedures as Functions" in BOL

Hi group, I have a select statement that if run against a 1 million record database directly in query analyzer takes less than 1 second.
