Question

I recently transferred a database from a windows box to a linux box. The tables are mixed between lower and upper case names. I need a way to rename all tables and columns to lowercase. Is that possible?

I see in this SO answer it’s possible for tables, but have not found anything that deals with column names.

Answer 1

You can try to do exact same thing with Information_Schema.Columns table

EDIT:
Something like

SELECT CONCAT('ALTER TABLE ', TABLE_NAME, ' CHANGE `', COLUMN_NAME, '` `',
LOWER(COLUMN_NAME), '` ', COLUMN_TYPE, ';')
FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = '{your schema name}'
