Procedure Analyse helps you find the optimal data type for the column values in a table.

Usage is very simple:

SELECT … FROM … WHERE … PROCEDURE ANALYSE([max_elements,[max_memory]])

A range of statistics and recommended data types and are returned for each column in your table.

For more information see the MySQL Docs on using Procedure Analyse.
