5 The DB2 Data Provider : Using Stored Procedures

Using Stored Procedures
The DB2 data provider supports multiple result sets and return codes from DB2 stored procedures when parameters are bound as return codes. The stored procedures must take an argument list.
NOTES:
Using Named Parameters
Using named parameters in stored procedures lets you bind parameters by name. This means that you do not have to enter the parameters in order.
Alternatively, you can use provider-specific parameter markers and binding behavior with your existing applications. The Parameter Mode connection string option specifies the behavior of native parameter markers and binding. This allows applications to reuse provider-specific SQL code and simplifies migration to the Progress DataDirect data providers. The data provider supports the colon or the @ parameter marker in a stored procedure.
