When an SQL statement executes, the database server automatically returns information about the success or failure of the statement in a C structure that is called http://www.pacs.tju.edu/informix/answers/english/docs/dbdk/infoshelf/esqlc/11.fm3.html sqlca. To obtain exception information, your ESQL/C program can access the sqlca structure or the SQLCODE variable as follows: The sqlca structure. You can use C statements to http://www.justskins.com/forums/error-100-a-319933.html obtain additional exception information. You can also obtain information relevant to performance or the nature of the data that is handled. For some statements, the sqlca structure contains informix sql warnings. The SQLCODE variable directly. You can obtain the status code of the most-recently executed SQL statement. SQLCODE holds an Informix-specific error-code, which is copied from the sqlca.sqlcode field. Important: ESQL/C supports the sqlca structure for backward compatibility. Informix recommends, however, that new applications use the SQLSTATE variable with the GET DIAGNOSTICS statement to perform exception checking. statement error number This method conforms to X/Open and ANSI SQL standards and supports multiple exceptions (page 11-6). The next three sections describe how to use the SQLCODE variable and the sqlca structure to perform exception handling. These sections cover the following topics: Understanding the sqlca structure Using the SQLCODE variable to obtain error codes Checking for the different types of exceptions with the sqlca structure Fields of the sqlca Structure Figure 11-13 contains the declaration of the sqlca structure from the sqlca.h header file. The ESQL/C preprocessor automatically includes the sqlca.h header file in an ESQL/C program. struct sqlca_s { long sqlcode; char sqlerrm[72]; /* error message parameters */ char sqlerrp[8]; long sqlerrd[6]; /* 0 - estimated number of rows returned */ /* 1 - serial value after insert or ISAM error code */

I carry this same statemetnt out immediately following the failure using dbaccess and it is successful. Does any one know what other mewanings error 100 may have.

The database server did not find any more data. This message is an ANSI-standard SQLCODE value. If you attempted to select or fetch data, you encountered the end of the data, or no data matched the criteria in the WHERE clause. Check for an empty table. Use this SQLCODE value to determine when a statement reaches the end of the data. For more information, see the discussion of SQLCODE in the INFORMIX-ESQL/C Programmer's Manual. The database server can return this SQLCODE value to a running program. Does that help? -- J
