To implicitly invoke the specified cast routine on an assignment operation if both of the following statements are true:
  • The source data type of the assignment is compatible with the source data type of the cast result.
  • The target data types are identical.
Note that an assignment operation is defined to be any of the following operations:
  • INSERT
  • UPDATE
  • parameter passing

You can disable this functionality by means of the DisableImplCastForSysFuncOp DBS Control parameter.

Be very careful if you are performing a REPLACE CAST statement because the system updates the UDTCast dictionary to reflect the value of the AS ASSIGNMENT flag.
