Sometimes you want to see on a glance what data you got in a system. Here are some examples.
select * from (
SELECT 'products',count(*) FROM m_product
UNION
SELECT 'product categories',count(*) FROM m_product_category
UNION
SELECT 'pricelists',count(*) FROM m_pricelist
UNION
SELECT 'prices',count(*) FROM m_productprice
UNION
SELECT 'discountschema',count(*) FROM m_discountschema
UNION
SELECT 'Partners',count(*) FROM c_bpartner
UNION
SELECT 'Partnergroups',count(*) FROM c_bp_group
) as foo
order by count
