How can I get the number of rows and columns that are in an SQL table?
Thank you for such a lovely short question. The number of rows is easy:
select count(*) as rows from daTable
As for the number of columns, that's a bit trickier:
select count(*) as columns from information_schema.columns where table_name = 'daTable'
The INFORMATION_SCHEMA tables (actually, they're views) are the standard SQL way of storing information about your database, and you are allowed to query them too.
