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

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 |
+------------+--------------+-------------+
3 rows in set (0.00 sec)
