Extract SYNONYM and SEQUENCE from Informix metadata We are migrating Informix database to oracle. Please help us to extract SYNONYM and SEQUENCE from Informix metadata using query.
Although you don't mention the version of the informix, try the ones above.

I believe that since V9.4 there is a system catalog table named SYSSEQUENCES where you can find the information about sequences on each database.

For the synonyms the one to be used is SYSSYNTABLE, if you have an older version try the SYSSYNONYMS.
