How I can only get the first of them?? Clean-up functions of this sort are sometimes needed, but they generally need more sophisticated design. All rows were deleted. Using Transaction Logging The best way to prepare for any kind of error during a modification is to use transaction logging.
Direct Deletions You can embed a DELETE statement in a program. Native error: -268 Error message: [Informix][Informix ODBC Driver][Informix] Unique constraint (informix.u364_896) violated. This problem has many possible causes, including a locked table or a full disk. The field sqlca.sqlcode is the SQL error (ie the -252 you saw) and sqlca.sqlerrd is the ISAM error if sqlcode is < 0.
