The SQL LCASE() function is used to convert a text or string value to lower case values.

Example Customer Table

The following data table is for example only. Let's use LCASE() function to convert the customer name to all lower case. The column we going to use is the Name column.

ID Name Age
1 Thomas Anderson 45
2 Andrew Golden 38
3 Ken Tom 30
4 Andrew Golden 36
5 Timonthy Kirk 32
6 Kelly Smith 39

Example of Running SQL Query

SELECT ID, LCASE(Name) AS Name, Age
FROM   Customers

After running the above query, it will return the following result.
