Yes, it is possible to use UPDATE query with LIMIT in MySQL. Let us see how.
For our example, we will first create a table. The CREATE command is used to create a table.
mysql>CREATE table tblUpdateLimit -> ( -> id int, -> name varchar(100) -> ); Query OK, 0 rows affected (0.53 sec)
Records are inserted with the help of INSERT command.
mysql>INSERT into tblUpdateLimit values(1,'John'); Query OK, 1 row affected (0.54 sec) mysql>INSERT into tblUpdateLimit values(2,'Carol'); Query OK, 1 row affected (0.12 sec) mysql>INSERT into tblUpdateLimit values(3,'Smith'); Query OK, 1 row affected (0.10 sec) mysql>INSERT into tblUpdateLimit values(4,'Kayle'); Query OK, 1 row affected (0.44 sec) mysql>INSERT into tblUpdateLimit values(5,'David'); Query OK, 1 row affected (0.13 sec) mysql>INSERT into tblUpdateLimit values(6,'Jason'); Query OK, 1 row affected (0.18 sec) mysql>INSERT into tblUpdateLimit values(7,'Larry'); Query OK, 1 row affected (0.15 sec) mysql>INSERT into tblUpdateLimit values(8,'Serhat'); Query OK, 1 row affected (0.15 sec) mysql>INSERT into tblUpdateLimit values(9,'Winny'); Query OK, 1 row affected (0.18 sec)
To display the above table, here is the query.
mysql> SELECT *from tblUpdateLimit;
The following is the output.
+------+--------+ | id |name | +------+--------+ | 1 | John | | 2 | Carol | | 3 | Smith | | 4 | Kayle | | 5 | David | | 6 | Jason | | 7 | Larry | | 8 | Serhat | | 9 | Winny | +------+--------+ 9 rows in set (0.00 sec)
Let us now see the syntax to use UPDATE query with limit.
UPDATE yourTableName SET column_name='some value’' WHERE column_name1 IN ( SELECT column_name1 FROM ( select column_name1 from yourTableName order by column_name1 asc limit integerValue,integerValue) anyAliasName );
Implementing the query now to fulfil our purpose and using it to set the name ‘Adam’, with limit 7.
mysql> UPDATE tblUpdateLimit SET name = 'Adam' -> WHERE id IN ( SELECT id FROM ( select id from tblUpdateLimit order by id asc limit 0,7)l); Query OK, 7 rows affected (0.27 sec) Rows matched: 7 Changed: 7 Warnings: 0
Check whether the table is updated or not.
mysql> SELECT *from tblUpdateLimit;
Here is the output.
+------+--------+ | id | name | +------+--------+ | 1 | Adam | | 2 | Adam | | 3 | Adam | | 4 | Adam | | 5 | Adam | | 6 | Adam | | 7 | Adam | | 8 | Serhat | | 9 | Winny | +------+--------+ 9 rows in set (0.00 sec)
