Hi Guru's,
I am trying to access few table present in DB2 LUW from postgres database.
All commands work fine, however when I try to select data from table it
throws error:
pg@a92a3741d40e:~/odbc_fdw$ psql -d postgres
psql (10.1)
Type "help" for help.
postgres=# create extension odbc_fdw;
CREATE EXTENSION
postgres=# CREATE SERVER odbc_db2 FOREIGN DATA WRAPPER odbc_fdw OPTIONS
(dsn 'SAMPLE');
CREATE SERVER
postgres=# CREATE USER MAPPING FOR pg SERVER odbc_db2 OPTIONS (odbc_UID
'db2inst1', odbc_PWD 'db2inst1');
Assuming using this:
https://github.com/ZhengYang/odbc_fdw
I believe that should be username and password per above link:
"CREATE USER MAPPING FOR postgres
SERVER odbc_server
OPTIONS (username 'root', password '');
"
CREATE USER MAPPING
postgres=#
postgres=# CREATE FOREIGN TABLE
postgres-# odbc_testt (
postgres(# id integer
postgres(# )
postgres-# SERVER odbc_db2
postgres-# OPTIONS (
postgres(# odbc_database 'SAMPLE',
Is the above the database name as well as the DSN name?
postgres(# odbc_schema 'db2inst1',
postgres(# sql_query 'select x from `db2inst1`.`TESTT`',
Is the column name case sensitive, because below it shows up as X?
I would try without the sql_query and sql_count queries as they are
optional.
postgres(# sql_count 'select count(id) from `db2inst1`.`dblist`'
postgres(# );
CREATE FOREIGN TABLE
postgres=# select * from odbc_testt;
