InnoDB I_S.tables.table_rows out by a factor of 100x
+1 Vote Up -0Vote Down

I’ve always believed that the MySQL Information_schema.tables.table_rows figure for Innodb tables to be while approximate, approximately accurate.

Today I found that the figures varied on one table from 10x to 100x wrong.

Before performing an ALTER I always verify sizes for reference.
