Hi,
Hi, I'm a novel developer of MySql and now I am trying to create a mysql
query to detect table updates.
I query a database table every X seconds, and i want to get only the
different rows in the table. The result that I want to have is simply

Bad News if you are counting against InnoDB

SELECT table_rows FROM information_schema.tables WHERE table_schema='given db
name' and
MySql table update/difference

another one with this query I detect
