Dear list - I am having a problem using RODBC to access records from tables in a PostgreSQL database. There is no problem establishing the connection using chnl <- odbcConnect (dsn= ... etc. The DSN seems to be properly set up using the PostgreSQL Unicode ODBC driver, and sqlTables(chnl) works OK and produces a list of tables in the database (they are all in a schema called 'source'). But
seiz.df <- sqlFetch(chnl, 'source.MAIN')
fails with the error message Error in odbcTableExists(channel, sqtable) : 'source.main': table not found on channel This occurs even though the table 'MAIN' is listed in schema 'source' in the output of sqlTables(chnl). I am using PostgreSQL version 9.0 and the database is installed on a local server (localhost) on a PC running Windows 7 and R2.12.1. I have tried version 8.4 of PostgreSQL with the same results. The local setup is for development purposes and the final database will eventually be installed on a remote server. A further bit of info: I am able to access another PostgreSQL database on a remote server for a different project with no problems. However, the server is running version 7.4 of PostgreSQL. Any help would be much appreciated. Many thanks, Bob Burn [[alternative HTML version deleted]]
