HELP with Database Cursor

I have been trying to execute ESQL/C commands on a SPARC10 running 4.1.3 with very little success. I have a cursor that has been PREPAREed and DESCRIBEed. The cursor is then opened with the argument input to the program from a file received from another site. This is not the only cursor that is described and used this way but they seem to be working OK. The cursor is used to FETCH a record the first time around in the function, this record is not expected to be found, the cursor is then closed and opened again using a argument in the where clause. This record is expected to be found on the FETCH. The return code I get from sqlca.sqlcode is -400. Of course this code is not listed in any of the Informix manuals I have so that is why I am posting this to the net. The select clause used is "select * from table1 where num = ?" I am running Informix-SE Version 4.13 UD1 Informix-SQL Informix-ESQL/C This is a "c" program and ran fine on a 3B2 SVR3 machine but failed when I ported it to the SUN machine. I was running Informix 2.1 or close to that release. Any and all help will be greatly appreciated. -- Gary T. Butler Email network gbutler@netcom.com
