The following additional rules apply to a call argument when the CALL statement is submitted from another stored procedure:
  • An IN argument must be a value expression.

    Identifiers in the value expression prefixed by the COLON character (:), if any, must refer to local variables, status variables, IN and INOUT parameters, or for-loop variable qualified columns and aliases of the calling procedure.

  • An INOUT argument must be a value expression that is limited to the form of an OUT-call-variable. The identifier must be prefixed with a COLON character and must refer to a local variable or an INOUT parameter of the calling procedure.
  • An OUT argument must be an OUT_call_variable. The identifier must refer to a local variable or an INOUT or OUT parameter.
