How to find rows that have a value that contains a lowercase letter

Question

I\'m looking for an SQL query that gives me all rows where ColumnX contains any lowercase letter (e.g. \"1234aaaa5789\"). Same for uppercase.

Answer 1

I have to add BINARY to the ColumnX, to get result as case sensitive

SELECT * FROM MyTable WHERE BINARY(ColumnX) REGEXP '^[a-z]';
