Hi ,

All informix table details will be stored in the some of the catalog tables like systables, sysindexes, syscolumns etc .. One of the catalog table values should have got corrupted bcos of which u are getting this error. Kindly check up from systables what is the tabid for the table name. Note it down and login as informix user and delete from syscolumns where tabid = "the table id "
delete from sysindexes where tabid = "table id "
and in the end delete from systables where tabid = "table id " .

Please ensure that u note downt the correct table id number from the systables. For getting the table id . execute the following query

select tabid from systables where tabname = <table name in quotes>

Check it out

Thanks
