Using ROWID columns
Automatic ROWID columns is not a common database feature.
Rowids are implicit primary keys generated by the database engine. Not all database servers support rowids:
| Database Server Type | Rowid keyword | Rowid type | ROWID support | 
|---|---|---|---|
| IBM® DB2® LUW | No | N/A | Yes, see details | 
| IBM Informix® | ROWID | 
INTEGER |

| IBM Netezza | No | N/A | Yes, see details | 
| Microsoft™ SQL Server (2) | No | N/A | No, see details | 
| Oracle® MySQL | No | N/A | No, see details |

| SAP® ASE | No | N/A | No, see details |

Informix fills the SQLCA.SQLERRD[6] 
        register with the ROWID of the last updated row. This register
is an INTEGER and cannot be          filled with rowids having CHAR(*)
type.
Search for ROWID and SQLCA.SQLERRD[6] in your code and review the code to remove the usage of rowids.
