MySQL query to remove everything except the last 7 characters in column record
Let us first create a table −
mysql> create table DemoTable ( Strength text ); Query OK, 0 rows affected (0.51 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('John is a good programmer');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable values('Chris is a good player in cricket');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('Bob is good in algorithm');
Query OK, 1 row affected (0.42 sec)Display all records from the table using select statement −
mysql> select *from DemoTable
This will produce the following output −
+-----------------------------------+ | Strength | +-----------------------------------+ | John is a good programmer | | Chris is a good player in cricket | | Bob is good in algorithm | +-----------------------------------+ 3 rows in set (0.00 sec)
Following is the query to remove everything except the last 7 characters in column record −
mysql> update DemoTable set Strength=substr(Strength,-7,7); Query OK, 3 rows affected (0.46 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+----------+ | Strength | +----------+ | grammer | | cricket | | gorithm | +----------+ 3 rows in set (0.00 sec)
