Re: Accessing DB2 tables from postgresql

Hello,

I dropped and recreated foreign table with odbc_database option. Also tried
to use import foreign schema object still getting same error.

CREATE FOREIGN TABLE
odbc_table (
CTGRY_ID INTEGER,
CTGRY_CD VARCHAR(10),
UPDT_TS TIMESTAMP
)
SERVER odbc_server
OPTIONS (
odbc_database 'TESTV9',
schema 'u90nmqd',
sql_query 'select CTGRY_ID,CTGRY_CD,UPDT_TS from `schema1`.`table1`',
sql_count 'select count(CTGRY_ID) from `schema1`.`table1`'
);

I have created server with below definition:
CREATE SERVER odbc_server FOREIGN DATA WRAPPER odbc_fdw OPTIONS (dsn
'TESTV9');

To test for other DBMS, I created foreign object for postgres with
odbc_fdw, however it is throwing too long encoding error.

Does ODBC wrapper support DB2 access?

Thanks,
Swapnil Vaze
