How to use MySQL SELECT LEFT to fetch the records containing string with slash

Let us first create a −

mysql> create table DemoTable1418
   -> (
   -> EmployeeCode text
   -> );
Query OK, 0 rows affected (0.51 sec)

Insert some records in the table using insert −

mysql> insert into DemoTable1418 values('EMP-2110/Carol');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1418 values('EMP-1900/David');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable1418 values('EMP-2345/Mike');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select −

mysql> select * from DemoTable1418;

This will produce the following output −

+----------------+
| EmployeeCode   |
+----------------+
| EMP-2110/Carol |
| EMP-1900/David |
| EMP-2345/Mike  |
+----------------+
3 rows in set (0.00 sec)

Here is the query to use SELECT LEFT in MySQL to fetch the above records before slash −

mysql> select left(EmployeeCode,8) from DemoTable1418;

This will produce the following output −

+----------------------+
| left(EmployeeCode,8) |
+----------------------+
| EMP-2110             |
| EMP-1900             |
| EMP-2345             |
+----------------------+
3 rows in set (0.00 sec)
