[R] Re trieving comments from PostgreSQL tables with RODBC and psqlodbc
I don't know whether this is an RODBC issue, a psqlodbc issue or a PostgreSQL issue; I've searched the documentation and forums for each, with no success. I want to list all the tables in a PostgreSQL schema, and return the table comments as well as the table names. As an example, one table is defined as follows: CREATE TABLE scen990.ezone_locationprice_year1 ( ezone integer NOT NULL, lprice_man_year1 real, lprice_war_year1 real, lprice_ret_year1 real, lprice_gen_year1 real, lprice_med_year1 real, lprice_gov_year1 real, CONSTRAINT ezone_locationprice_year1_pkey PRIMARY KEY (ezone) ) WITHOUT OIDS; ALTER TABLE scen990.ezone_locationprice_year1 OWNER TO mscope; COMMENT ON TABLE scen990.ezone_locationprice_year1 IS 'calculated'; The RODBC function sqlTables() returns all the tables, but the records look like this: TABLE_QUALIFIER TABLE_OWNER TABLE_NAME TABLE_TYPE REMARKS mscope scen990 ezone_locationprice_year1 TABLE All the REMARKS values are empty strings. Can I get it to return the COMMENT ON values instead? (the table_owner and tablet_qualifier are switched but that doesn't worry me) I'm using R 2.8.1, RODBC 1.2-4, psqlodbc 8.0.2, and PostgreSQL 8.1.5 .

Re: [R] Re trieving comments from PostgreSQL tables with RODBC and psqlodbc
You seriously need to update your way-obsolete software (see the posting guide), but you are seeing what your ODBC driver is returning, not an R issue. R-sig-db is a better list for help on database connectivity.

Upgrading the driver did not help, but you're right, I should have tried that first. Thank you for your response.
