The following additional rules apply to a call argument when the CALL statement is submitted from a PP2 embedded SQL application:
- An IN argument must be a value expression.
Identifiers in the value expression prefixed by the COLON character (:), if any, must refer to host variables. The value of the expression is treated as the input value for the corresponding parameter.
- An INOUT argument must be a value expression that is limited to the form of an OUT_call_variable. The identifier must refer to a host variable.
- An OUT argument must be an OUT_call_variable. The identifier must refer to a host variable.
