Informix Error Messages and Error Codes From Error 437 to 451
Informix Error Code -437 Connection must be established before registering callback function.
You attempted to register a callback function before you connected to a database server. You must first connect to a database server and then register your callback function.
-438 Call back function must be NULL if time-out value is -1.
You provided an incorrect value to unregister your callback function. Pass a null value, not a function pointer, to the callback function.
Informix Error Code -439 Database server is currently processing an SQL task.
You attempted to call an SQL routine or attempted to execute an SQL statement within a signal handling function/routine or a callback function/procedure. Use only the sqldone() and sqlbreak() library functions inside your INFORMIX-ESQL/C callback function. Use only the ECO-SQD and ECO-SQB library routines inside your ESQL/COBOL callback procedure. In addition, if you want to unregister your callback function in INFORMIX-ESQL/C, you can invoke the sqlbreakcallback() callback registration function within your callback procedure. If you want to unregister your callback procedure in ESQL/COBOL, you can invoke the ECO-SQBCB callback registration routine within your callback procedure.
Informix Error Code -450 Illegal ESQL locator, or uninitialized blob variable in 4GL.
A BYTE or TEXT host variable used in this statement is not valid. If this is a 4GL program, the variable has not been initialized by use of the LOCATE statement, or was freed after being located. Review the program logic to ensure all blob variables are located before use. If this is ESQL/C, the locator structure is invalid or uninitialized. Check that all locator structures are allocated and filled in before use.
Informix Error Code -451 Locator buffer size too small.
The locator structure provided for a BYTE or TEXT value in this statement specifies a memory buffer that is smaller than the value (in the loc_bufsize field). The actual size is in loc_indicator. No data was transferred. Revise the program to use a larger buffer, to locate the value in a file instead of memory, or to pass the value in segments through a user-provided read function. Alternatively, you can specify a substring of the value in the SELECT statement. If this is a 4GL program, this error should not occur. If the error recurs, please note all circumstances and contact Informix Technical Support.

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.
