Script to extract the DDL in AWS RedShift
If you wanna find the table details/description you can use the below script and output the full metadata for a table.
Just replace INSERT_TABLENAME_HERE and INSERT_SCHEMA_NAME_HERE with the scheme and table name.
SELECT DISTINCT n.nspname AS schemaname
,c.relname AS tablename
,a.attname AS COLUMN
,a.attnum AS column_position
,pg_catalog.format_type(a.atttypid, a.atttypmod) AS TYPE
,pg_catalog.format_encoding(a.attencodingtype) AS encoding
,a.attisdistkey AS distkey
,a.attsortkeyord AS sortkey
,a.attnotnull AS notnull
,a.attencodingtype AS compression
,con.conkey AS primary_key_column_ids
,con.contype AS con_type
FROM pg_catalog.pg_namespace n
,pg_catalog.pg_class c
,pg_catalog.pg_attribute a
,pg_constraint con
,pg_catalog.pg_stats stats
WHERE n.oid = c.relnamespace
AND c.oid = a.attrelid
AND a.attnum 0
AND c.relname NOT LIKE '%pkey'
AND lower(c.relname) = 'INSERT_TABLENAME_HERE'
AND n.nspname = 'INSERT_SCHEME_NAME_HERE'
AND c.oid = con.conrelid(+)
ORDER BY A.ATTNUM
;
