Informix Error Messages and Error Codes From Error 228 to 232

SQLServerF1

Informix Error Code -228 UPDATE or INSERT on ROWID prohibited.
This statement names the column ROWID in the list of columns for insertion or update. The row ID is an intrinsic property that cannot be modified. You can select it in a SELECT statement and compare it in a WHERE clause, but you cannot modify its contents.
Informix Error Code -229 Could not open or create a temporary file.
The database server cannot create a temporary disk file. The file should be created in the directory that the DBTEMP environment variable specifies (or /tmp by default on UNIX systems). Check the accompanying ISAM error code and look for operating-system error messages that might give more information. Possibly your account does not have write permission in that directory, or the disk is full. Since Version 5.01, the INFORMIX-SE database server uses the DBTEMP environment variable, but Informix Dynamic Server and INFORMIX-OnLine Dynamic Server do not.

On a UNIX system, try increasing the maximum number of open files (NFILES parameter on some systems) to approximately 400.
Informix Error Code -230 Could not read a temporary file.
The database server created a temporary file in the directory specified by the DBTEMP environment variable (or /tmp by default on UNIX systems) but encountered an error when it tried to read the file back. Check the accompanying ISAM error code, and look for operating-system error messages that might give more information. Possibly a hardware failure occurred, or possibly another user erased the temporary file accidentally. Since Version 5.01, the INFORMIX-SE database server uses the DBTEMP environment variable, but Informix Dynamic Server and INFORMIX-OnLine Dynamic Server do not.

Informix Error Code -231 Cannot perform aggregate function with distinct on expression.
This statement selects DISTINCT (expression) within an aggregate function. This action is not supported. Select the DISTINCT value and other columns into a temporary table; then select ALL from that table applying the aggregate function.
Informix Error Code -232 A SERIAL column column-name may not be updated.
You cannot alter the contents of a column with the SERIAL data type in the UPDATE statement, even when the updating value is zero. (You can specify a value of zero for a serial column when you use the INSERT statement; the database server ignores the zero and inserts a generated number.) Revise the statement so that only nonserial columns are updated.

Above are list of Informix Error Messages and Errors Codes or Status Codes or Exit Codes along with Error and Warning messages received while performing certain operation against Informix applications or related products.

What are Informix Error Messages?
All Informix messages returned by the Informix server are assigned an error code.

In general, each Informix error contains the following information:
• The Informix Error Code or Informix Error status
• The message text. This text is usually returned with the Error code. Some messages employ word substitution, where the word substituted represents the system-replacement of a term more specific to the occurrence.
• An explanation of how the error may have occurred.

Hope this was helpful.
