Informix Error Messages and Error Codes From Error 401 to 404
Informix Error Code -401 Fetch attempted on NULL cursor.
This FETCH statement passed a cursor data structure that is invalid or a null pointer. Possibly the cursor has been freed with the FREE statement, or possibly the cursor data structure has been overwritten in memory.
Version 5.0 or later database servers do not return this error code. See errors -267 and -404.
Informix Error Code -402 Address of a host variable is NULL.
Review the way the program constructs the sqlda and related data structures; somehow it is setting up a null pointer. The error might be caused by using a row or collection host variable without having executed the necessary ALLOCATE statement.
If the program is in INFORMIX-4GL or another language in which the sqlda is not constructed directly by the program, or if this statement refers only to host variables by name, this error should not occur. If the error recurs, note all circumstances and contact Informix Technical Support.
Informix Error Code -403 The size of a received row disagrees with the expected size.
This internal error indicates a problem in the communication between the database server and the library functions that call it. Check that your program is at the same software level as the database server in use. If the error recurs, please note all circumstances and contact Informix Technical Support.
Informix Error Code -404 The cursor or statement is not available.
You probably used a statement that names a cursor that was released with the FREE statement. Review the program logic and check that the cursor specified is declared and opened, but not freed, prior to reaching this statement.
If the error occurred on a command that specifies a variable rather than a cursor, the statement was not prepared before you tried to execute it.
This error can also occur if the cursor or statement is not available because the connection to the server does not exist or was lost.

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.
