The LCASE() function converts the value of a field to lowercase.

SQL LCASE() Example

We have the following "Persons" table:

Id	LastName	FirstName	Address	City
1	Navis	Anto	Madras	TVL
2	Ji	Bala	Bombay	TVL
3	Christopher	Franklin	America	KK

Now we want to select the content of the "LastName" and "FirstName" columns above, and convert the "LastName" column to lowercase.

We use the following SELECT statement:

SELECT LCASE(LastName) as LastName,FirstName FROM Persons

The result-set will look like this:

LastName	FirstName
Navis	Anto
ji	Bala
Christopher	Franklin
