I'm noticing that across our several databases and hundreds of tables that column definitions are not consistent. I'm wondering if there is a tool or query (using INFORMATION_SCHEMA perhaps) that will show me all databases, tables and columns where they don't match (by column name).
For example in one table
foo_id might be UNSIGNED and in other's it is not. Or maybe it's INT(11) in some and INT(10) or worse MEDIUMINT in others. Or extending further Charset/Collation might mismatch and be that stupid "latin1_swedish_ci" and fixed to be "utf8" in others.
Stuff like that. I want to see everything where there is some difference.
