one example is IndexUsageToSizeRatio and IndexUSageToSizeRatio.

I found a quick way, I changed all case to lower case, the only change need to change is INFORMATION_SCHEMA.TABLE_CONSTRAINTS, which should be up case.

Thanks!

the scripts are assuming case insensitive...

I spent half hour just want to try to run it, but still not able to due to those up case/lower case.
