The possible values for SQLCODE are:
| Value | Meaning |
|---|---|
| 0 | The statement ran without error. |
| 1 | The statement ran, but a warning was generated. The values of the SQLWARN flags should be checked to determine the type of error. |
| 100 | Data matching the query was not found or the end of the results set has been reached. No rows were processed. |
| < 0 (negative) | The statement did not run due to an application, database, system, or network error. |
If you are using OpenESQL, the following error codes are defined for SQLCODE
| SQLCODE | Message | Meaning |
|---|---|---|
| 0 | Mismatch between number of parameter markers and host variables/user sqldas | Only used for special Embedded SQL statements, such as CONNECT. |
| 1 | NULL value returned but no indicator variable supplied | |
| -1 | Autoconnect failure | SQL(INIT) was used, and automatic CONNECT failed. Programs which use SQL(INIT) need to check SQLCODE immediately on startup. |
| -10000 | <The first error message returned by the ODBC call SQLError after the OpenESQL run-time module detected an error> | See your ODBC driver documentation, or other ODBC reference documents for details of ODBC error messages. SQLSTATE will contain a unique code for each ODBC error condition. |
| Unable to retrieve ODBC error | An ODBC error occurred, but no more details are available. This usually indicates a serious run-time condition, such as severe memory shortage. | |
| -19085 | Invalid ODBC catalog query | This is caused by invalid parameters to a QUERY ODBC statement. |
| -19101 | Statement too long | |
| -19199 | ESQL Keyword(s) detected in PREPARE/EXECUTE IMMEDIATE statement | |
| -19313 | Too few host variables | |
| -19413 | Data overflow occurred during decimal data conversion | |
| -19501 | No cursor declared | |
| -19514 | Cursor is not prepared | |
| -19701 | NULL connection name | These two errors (-19701 and -19702) occur when a program refers to a connection which does not exist. The most likely cause is attempting to execute an Embedded SQL statement before a CONNECT has executed successfully, or after all connections have been disconnected. |
| -19702 | Connection name not found | |
| -19703 | Could not make connection. | |
| -19707 | Duplicate connection name. | |
| -19822 | Improperly initialized User SQLDA | |
| -19957 | Statement text not found or empty | |
| -20000 | Unimplemented embedded SQL feature | The COBOL compiler may accept some Embedded SQL syntax which is not yet supported by the OpenESQL run-time module. If an attempt is made to execute such a statement, this condition is the result. |
