so thanks to all for the answers. But i'm going to be frustrated, no one of your solutions seems to work, and i can't understand why, because i've write another two functions that works well... I always obtain error: or unknown function (if i pass args without ' ') or "column not exist". i've noticed that on my postgres server, there's two database: one i've created for my scope, and another named postgres (i think created by default). Maybe should i specify on wich database my function should work (also if function compare only inside my personal database)? -- View this message in context: http://postgresql.1045698.n5.nabble.com/unable-to-call-a-function-tp5762590p5762649.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
