Re: Query to return schema/table/columname/columntype

You mean like this:


CREATE OR REPLACE VIEW sys_tabledef ASSELECT columns.table_catalog, columns.table_schema, columns.table_name, 
columns.column_name, columns.ordinal_position, columns.column_default, 
columns.is_nullable, columns.data_type, columns.character_maximum_length, 
columns.character_octet_length, columns.numeric_precision, 
columns.numeric_precision_radix, columns.numeric_scale, 
columns.datetime_precision, columns.interval_type, 
columns.interval_precision, columns.character_set_catalog, 
columns.character_set_schema, columns.character_set_name, 
columns.collation_catalog, columns.collation_schema, columns.collation_name, 
columns.domain_catalog, columns.domain_schema, columns.domain_name, 
columns.udt_catalog, columns.udt_schema, columns.udt_name, 
columns.scope_catalog, columns.scope_schema, columns.scope_name, 
columns.maximum_cardinality, columns.dtd_identifier, 
columns.is_self_referencing  FROM information_schema.columns WHERE columns.table_schema::text = 'public'::text ORDER BY
columns.table_name,columns.ordinal_position;
