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)
