ErrorCode Rules

The naming rule complies with the following rules: GS_[3-digit service ID][2-digit error type ID][4-digit auto-increment ID].

For example, GS_201110003 indicates a parameter error (11) in the row-column storage type (0) of the SQL module (2), Sub-error (0003) indicates the third error code of the same type (for example, the format of the parameter OID is incorrect).

For details about the current service and error type, see Table1 Description of Error Codes.
