Delete URLs with specific domains from MySQL database?
To delete URLs with specific domains, use DELETE and LIKE clause.
Let us first create a table −
mysql> create table DemoTable1361 -> ( -> URL text -> ) ; Query OK, 0 rows affected (0.58 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1361 values('Https://www.google.com//?id=1');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable1361 values('Https://www.facebook.com//?id=2&name=John');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable1361 values('Https://www.yahoo.com//?id=3');
Query OK, 1 row affected (0.31 sec)
mysql> insert into DemoTable1361 values('Https://www.google.com//?id=1');
Query OK, 1 row affected (0.16 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1361;
This will produce the following output −
+-------------------------------------------+ | URL | +-------------------------------------------+ | Https://www.google.com//?id=1 | | Https://www.facebook.com//?id=2&name=John | | Https://www.yahoo.com//?id=3 | | Https://www.google.com//?id=1 | +-------------------------------------------+ 4 rows in set (0.00 sec)
Here is the query to delete URLs with specific domains from MySQL database −
mysql> delete from DemoTable1361 where URL LIKE '%Https://www.google.com%'; Query OK, 2 rows affected (0.17 sec)
Let us check the table records once again −
mysql> select * from DemoTable1361;
This will produce the following output −
+-------------------------------------------+ | URL | +-------------------------------------------+ | Https://www.facebook.com//?id=2&name=John | | Https://www.yahoo.com//?id=3 | +-------------------------------------------+ 2 rows in set (0.00 sec)
