Обсуждение: function definition documentation
I am having an impossible time porting some simple Stored Procedures from Informix to postgres. The documentation is almostself defeating. Are there any better descriptions of how to define functions that return several tuples to a wide variety of calling programs(e.g. I can't count on my users running the psql command line tool, but rather coldfusion, jsp etc.) ? Thanks ! Greg Williamson DBA GlobeXplorer LLC

You might want to look at the "Set Returning Functions" at the techdocs site: http://techdocs.postgresql.org Most of your problems are down to quoting issues and misleading error statements. -- Richard Huxton Archonet Ltd
