MySQL query to separate and select string values (with hyphen) from one column to different columns

For this, you can use SUBSTRING_INDEX(). Let us first create a table −

mysql> create table DemoTable1962
   (
   EmployeeInformation text
   );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1962 values('101-John-29');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1962 values('102-David-35');
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1962 values('103-Chris-28');
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1962;

This will produce the following output −

+---------------------+
| EmployeeInformation |
+---------------------+
| 101-John-29         |
| 102-David-35        |
| 103-Chris-28        |
+---------------------+
3 rows in set (0.00 sec)

Here is the query to separate and select values from one column to different columns −

mysql> select substring_index(EmployeeInformation, '-', 1) as EmployeeId,
   substring_index(substring_index(EmployeeInformation,'-',2),'-',-1) AS EmployeeName,
   substring_index(substring_index(EmployeeInformation,'-',-2),'-',-1) AS EmployeeAge
   from DemoTable1962;

This will produce the following output −

+------------+--------------+-------------+
| EmployeeId | EmployeeName | EmployeeAge |
+------------+--------------+-------------+
| 101        | John         |          29 |
| 102        | David        |          35 |
| 103        | Chris        |          28 |
+------------+--------------+-------------+
