It’s a restriction of InnoDB. See http://dev.mysql.com/doc/refman/5.0/en/innodb-restrictions.html. It gives an approximate count, which fluctuates a lot.

Why does SUM(table_rows) fluctuate so wildly? I run this query:

SELECT CONCAT(SUM(table_rows)/1000000,’M') AS no_rows FROM information_schema.TABLES WHERE TABLE_SCHEMA = ”;

and no_rows was first 2.73M, then 2.83M, then 2.81M, then 2.78M, then 2.81M…?

Why does this vary?
