How to delete records based on a word with underscore like MONTH_JAN'?
For this, you can use LIKE operator. Let us first create a table −
mysql> create table DemoTable ( Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, Name varchar(40), BornMonth varchar(40) ); Query OK, 0 rows affected (0.47 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable(Name,BornMonth) values('Chris','MONTH_DEC'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable(Name,BornMonth) values('Bob','MONTH_JAN'); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable(Name,BornMonth) values('Mike','MONTH_FEB'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable(Name,BornMonth) values('David','MONTH_JAN'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable(Name,BornMonth) values('Carol','MONTH_MARCH'); Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----+-------+-------------+ | Id | Name | BornMonth | +----+-------+-------------+ | 1 | Chris | MONTH_DEC | | 2 | Bob | MONTH_JAN | | 3 | Mike | MONTH_FEB | | 4 | David | MONTH_JAN | | 5 | Carol | MONTH_MARCH | +----+-------+-------------+ 5 rows in set (0.00 sec)
Following is the query to delete records based on a word −
mysql> delete from DemoTable where BornMonth LIKE '%MONTH_JAN%'; Query OK, 2 rows affected (0.18 sec)
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+----+-------+-------------+ | Id | Name | BornMonth | +----+-------+-------------+ | 1 | Chris | MONTH_DEC | | 3 | Mike | MONTH_FEB | | 5 | Carol | MONTH_MARCH | +----+-------+-------------+ 3 rows in set (0.00 sec)
