You can't really call CheckGlobInit() directly. You can indirectly call sqli_stmt() by writing pretty much any regular SQL statement other than a SELECT... EXEC SQL SET ISOLATION TO DIRTY READ; > Or do we any flag which can trace what function & the corresponding > parameters is passed to a function & log it to a file. Please let me > know for the above two queries. Thanks in advance... No, there's no easy way to log that sort of information. In this case, I'd look hard at what's in the file cm022.ec at around line 134. Given the function name, I suspect that it is similar to the EXEC SQL statement I used as an example. CheckGlobInit() is a function that checks that the library is properly initialized - so a failure here is puzzling. One possibility is that you have a symbol clash with the Informix symbols - which the compiler/linker is not warning you about - and this is leading to disaster. I don't rate that as very likely, but it is a possibility. I wish there was an easy way to document the namespace the Informix uses, but there isn't. -- Jonathan Leffler #include <disclaimer.h> Email: jleffler@earthlink.net, jleffler@us.ibm.com Guardian of DBD::Informix v2003.04 -- http://dbi.perl.org/
