The LEN() function returns the length of the value in a text field.
SELECT LEN(column_name) FROM table_name |
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 length of the values in the "Address" column above.
We use the following SELECT statement:
SELECT LEN(Address) as LengthOfAddress FROM Persons |
The result-set will look like this:
LengthOfAddress |
---|
12 |
9 |
9 |
