The LCASE() Function
The LCASE() function converts the value of a field to lowercase.
SQL LCASE() Syntax
| SELECT LCASE(column_name) FROM table_name |
Syntax for SQL Server
| SELECT LOWER(column_name) FROM table_name |
SQL LCASE() Example
We have the following "Persons" table:
| P_Id | LastName | FirstName | Address | City |
| 1 | Hansen | Ola | Timoteivn 10 | Sandnes |
| 2 | Svendson | Tove | Borgvn 23 | Sandnes |
| 3 | Pettersen | Kari | Storgt 20 | Stavanger |
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 |
| hansen | Ola |
| svendson | Tove |
| pettersen | Kari |
