Hello, I need to access a database using two different schemas. During initialization the default schema is set as follows: set schema 'ucm'; Then later, I need to get data from a table in another schema 'ts_sofia_internal', so I tried the following, but it returns an error as shown: teo=# select * from sip_presence('ts_sofia_internal') where sip_presence.sip_user='1003'; ERROR: function sip_presence(unknown) does not exist LINE 1: select * from sip_presence('ts_sofia_internal') where sip_pr... ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. teo=# Does anyone know how I can do this? By the way, I will actually implement the query in C and connect to the DB via ODBC. Thanks, Jerry
