Using the LOWER() and UPPER() SQL Server 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 [dbo].[Courses] WHERE LOWER (education_delivery_method) = 'classroom'
Display a column in uppercase
You can use either the SQL Server UPPER() or LOWER() functions to format columns in your SQL SELECT.
SELECT TOP 10 UPPER (firstname), lastname FROM Students
Format a column using Upper and Lower functions
It is possible to use the SQL Server LOWER() and UPPER() functions in conjunction with the SUBSTRING() function to accomplish different types of formatting.
SELECT TOP 10 UPPER(SUBSTRING(lastname,1,1)) + LOWER(SUBSTRING(lastname,2,29)) AS 'Lastname' FROM Students
Update a group of rows changing case
It is possible to use the SQL Server UPPER() or LOWER() functions in conjunction with an update statement to change the "case" of a group of rows.
BEGIN TRANSACTION GO UPDATE [dbo].[Students] SET lastname = UPPER(lastname) WHERE student_id > 0 GO COMMIT TRANSACTION GO
