People have asked us on several occasions if there is such a construct
SELECT * EXCEPT(...list) FROM sometable. Sadly we do not think such a
thing exists in the ANSI SQL Specs nor in PostgreSQL.
The above feature would come in handy when you have certain fields in your tables that are common across tables, but you need to leave them out in your query. A common case of this is when you have PostGIS tables loaded using shp2pgsql with a fields called gid and the_geom which are not terribly useful for simple data queries.
There are 2 common ways we use to achieve this result.
Here are the steps:
SELECT 'SELECT ' || array_to_string(ARRAY(SELECT 'o' || '.' || c.column_name FROM information_schema.columns As c WHERE table_name = 'officepark' AND c.column_name NOT IN('officeparkid', 'contractor') ), ',') || ' FROM officepark As o' As sqlstmt
The above for my particular example table - generates an sql statement that looks like this
SELECT o.officepark,o.owner,o.squarefootage FROM officepark As o
