I'm attempting to retrieve data using a select statement without knowing
the column names. I know the ordinal position but not the name of the
column (happens to be a date::text and I have 13 fields).
Below provides the name of the column in position 3:
select column_name from (select column_name::text, ordinal_position from
information_schema.columns where
table_name='wk_test') as foo where ordinal_position = 3;
But how can I use the above as a column name in a normal select statement.
Unlike other databases I just can't use ordinal position in the select
statement - RIGHT???
