Strip last two characters of a column in MySQL?

You can strip last two characters with the help of SUBSTRING() and CHAR_LENGTH() methods. The syntax is as follows −

select yourColumnName,SUBSTRING(yourColumnName,1,CHAR_LENGTH(yourColumnName) - 2) AS anyVariableName from yourTableName;

To understand the above syntax, let us create a table −

mysql> create table LastTwoCharacters
   −> (
   −> Words varchar(200)
   −> );
Query OK, 0 rows affected (0.71 sec)

Now you can insert some records in the table with the help of select statement. The query to insert records is as follows −

mysql> insert into LastTwoCharacters values('Hellooo');
Query OK, 1 row affected (0.23 sec)

mysql> insert into LastTwoCharacters values('Worldsss');
Query OK, 1 row affected (0.10 sec)

mysql> insert into LastTwoCharacters values('Johnson');
Query OK, 1 row affected (0.22 sec)

Display all records with the help of select statement −

mysql> select *from LastTwoCharacters;

The following is the output −

+----------+
| Words    |
+----------+
| Hellooo  |
| Worldsss |
| Johnson  |
+----------+
3 rows in set (0.00 sec)

The following is the query to strip the last two characters of a column −

mysql> select Words,SUBSTRING(Words,1,CHAR_LENGTH(Words) - 2) AS AfterStripLastTwoChar from LastTwoCharacters;

The following is the output −

+----------+-----------------------+
| Words    | AfterStripLastTwoChar |
+----------+-----------------------+
| Hellooo  | Hello                 |
| Worldsss | Worlds                |
| Johnson  | Johns                 |
+----------+-----------------------+
3 rows in set (0.00 sec)
