Re: Question about odbc link to Oracle database from PostgreSQL

Hi Hans

Many many thanks, I have executed the SQL, how ever, it does not work,
I don't know what's wrong

tora=# select * FROM odbclink.query(1, 'SELECT * FROM test') as
result(user_name text,score number);
ERROR: type "number" does not exist
LINE 1: ...SELECT * FROM test') as result(user_name text,score number);
^
tora=# select * FROM odbclink.query(1, 'SELECT user_name,score FROM
test') as result(user_name text,score number);
ERROR: type "number" does not exist
LINE 1: ...e,score FROM test') as result(user_name text,score number);
^
tora=#
