Porting Sybase to Informix

Hello, this is Jess. Need some inputs with regards to the following issue: We are working on porting our application from Sybase DB Client/Sybase 4.9 to Informix ESQL/C/Informix OnLine 6.0 on the Stratus. Need some help with regards to this porting effort. Some of the key issues are the following: * Equivalent DB-Client APIs to Informix ESQL/C * Differences between Sybase stored procedure vs Informix's. * Differences between Sybase triggers vs Informix's * Referential integrity issues * Sybase RPCs calls Has anyone done this exercise before? Please help as to the guidelines... We also have an application that needs to access the Sybase on the HP9000 and Informix on the Stratus machine. Has anyone tried doing this from a SUN Sparc workstation accessing as clients to both Informix and Sybase? Please advise. We have a tight schedule with regards to the porting of this applications. Please help... Any ideas will be much appreciated. Please reply via email to jesskung@solomon.technet.sg. Thanking in advance! Thank you and take care, Jessica
