Re: How to get the data from the query

Running this query:

draft=# SELECT DISTINCT column_name, data_type,
character_maximum_length, character_octet_length, numeric_precision,
numeric_precision_radix, numeric_scale, is_nullabl
e, column_default, ordinal_position, CASE WHEN column_name IN (SELECT
ccu.column_name FROM information_schema.constraint_column_usage ccu,
information_schema.table_con
straints tc WHERE ccu.constraint_name = tc.constraint_name AND
tc.constraint_type = 'PRIMARY KEY' AND ccu.table_name = 'leagues' )
THEN 'YES' ELSE 'NO' END AS is_pk F
ROM information_schema.columns WHERE table_name='leagues' ORDER BY
ordinal_position;

still produces good results:

column_name | data_type | character_maximum_length |
character_octet_length | numeric_precision | numeric_precision_radix |
numeric_scale | is_nullable | col
umn_default | ordinal_position | is_pk
--------------+-------------------+--------------------------+------------------------+-------------------+-------------------------+---------------+-------------+----

(8 rows)

lines 1-12/12 (END)

Thank you.
