Well, if the tables are mostly static and you have current statistics
OR your tables are very dynamic and you have sufficiently recent
statistics, selecting from the catalog works great:
select tabname, card from syscat.tables where tabschema =
'<schemaName>'
(noting that for very dynamic table sizes, the exact COUNT(*) isn't
often accurate in any case for long). |
