Using the LOWER() and UPPER() MySQL Functions
Return rows for a column case insensitive
It is common practice to make a column case insensitive to ensure that you return all of the desired rows.
SELECT * FROM Courses WHERE LOWER(education_delivery_method) = 'classroom'
Display a column in uppercase
You can use either the MySQL UPPER() or LOWER() functions to format columns in your SQL SELECT.
SELECT UPPER(firstname), lastname FROM Students LIMIT 10
Format a column using Upper and Lower functions
It is possible to use the MySQL LOWER() and UPPER() functions in conjunction with the SUBSTRING() function to accomplish different types of formatting.
SELECT CONCAT(UPPER(SUBSTRING(lastname,1,1)),LOWER(SUBSTRING(lastname,2,29))) AS 'Name' FROM Students LIMIT 10
Update a group of rows changing case
It is possible to use the MySQL UPPER() or LOWER() functions in conjunction with an update statement to change the "case" of a group of rows.
START TRANSACTION ; UPDATE Students SET lastname = UPPER(lastname) WHERE lastname LIKE 'Jones%' ; COMMIT ;
