From time to time, you will encounter stored procedures that return resultsets you need to process. This is not as simple as it sounds. One option is to receive the resultset in a client application or middleware component and to process it further from there. Sometimes this option is not acceptable for a variety of reasons. For example, the resultset might be too big and network traffic could be considerably increased in this way. Since the resultset needs to be transferred to the middleware server before it is processed, the performance of the system could be degraded. There might be security implications for example, if a user should have access only to a segment of a resultset and not to the complete resultset. Another option is to copy the source code of the stored procedure into your stored procedure. This could be illegal. It will also reduce the maintainability of your code since you have two copies to maintain. If the other stored procedure is a system stored procedure, Microsoft can change its internals with the release of each new version of SQL Server. Your stored procedure will then need to be changed. It is possible to collect the resultset of a stored procedure in Transact-SQL code. You need to create a (temporary) table, the structure of which matches the structure of the resultset exactly, and then redirect (insert) the resultset into it. Then you can do whatever you want with it. The following stored procedure uses the sp_dboption system stored procedure to obtain a list of all database options and to obtain a list of database options that are set on the Asset database. Records that have a structure identical to that of the resultset as returned by the stored procedure are collected in temporary tables. The Insert statement can then store the resultset in the temporary table. The contents of the temporary tables are later compared and a list of database options not currently set is returned to the caller.

Advanced Stored Procedure Programming
As Set Nocount On Create Table #setable ( name nvarchar(35) ) Create Table #current ( name nvarchar(35) ) -- collect all options Insert Into #setable Exec sp_dboption -- collect current options Insert Into #current Exec sp_dboption @dbname = @chvDBName -- return non-selected Select name non_selected From #setable Where name not in ( Select name From #current ) Drop Table #setable Drop Table #current Return 0
The only trouble with this method is that you need to know the structure of the resultset of the stored procedure in advance in order to create a table with the same structure. This is not a problem for user-defined stored procedures. It used to be a problem for system
SQL Server 2000 Stored Procedure Programming
stored procedures, but SQL Server Books Online now provides that information.
NOTE: Unfortunately, it is not possible to collect information if a stored procedure returns more than one resultset, as is the case with sp_spaceused.
This technique also works with the Exec statement. For example, if you try to collect a resultset from the DBCC command this way, SQL Server will return an error. But you can encapsulate the DBCC statement in a string and execute it from Exec. The following stored procedure returns the percentage of log space used in a specified database:
Create Procedure prLogSpacePercentUsed -- return percent of space used in transaction log for -- specified database ( @chvDbName sysname, @fltPercentUsed float OUTPUT ) As Set Nocount On Declare @intErrorCode int Set @intErrorCode = @@Error If @intErrorCode = 0 Begin Create Table #DBLogSpace ( dbname sysname, LogSizeInMB float, LogPercentUsed float, Status int ) Set @intErrorCode = @@Error End
