You can specify dynamic parameters in a prepared EXECUTE PROCEDURE statement. Dynamic input parameters are passed from host variables or an SQLDA data buffer in the application to procedure parmeters. Dynamic output parameters are passed from procedure parameters to host variables or an SQLDA data buffer in the application. Table 5-2 “When Dynamic Parameters are Passed Between an Application and a Procedure”
shows when dynamic parameter values are passed.
Table 5-2 When Dynamic Parameters are Passed Between an Application and a Procedure
| Type of Processing | Input Parameter Values | Output Parameter Values |
|---|
| Cursor Processing | OPEN | CLOSE |
| Non-Cursor Processing | EXECUTE PROCEDURE | EXECUTE PROCEDURE |
The following statement contains three dynamic procedure
parameters:
EXECUTE PROCEDURE ? = InventoryReport (?, ? OUTPUT)
|
Note that a procedure return status is always an output (only) parameter. Any other dynamic procedure parameter is assumed to be for input only unless OUTPUT or OUTPUT ONLY is specified.
Refer to the ALLBASE/SQL Reference Manual for complete syntax and to the "Using Parameter
Substitution in Dynamic Statements" chapter in this manual.
