MySQL query to get the character length for all the values in a column?
To get the character length, use the CHAR_LENGTH() method. Let us first create a table −
mysql> create table DemoTable
-> (
-> Name varchar(100)
-> );
Query OK, 0 rows affected (1.04 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Bob');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable values('David');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+--------+
| Name |
+--------+
| John |
| Robert |
| Bob |
| David |
+--------+
4 rows in set (0.00 sec)
Get the character length −
mysql> select char_length(Name) from DemoTable;
This will produce the following output −
+-------------------+
| char_length(Name) |
+-------------------+
| 4 |
| 6 |
| 3 |
| 5 |
+-------------------+
4 rows in set (0.00 sec)
