Match the elements of an array in a MySQL query
Let us first create a table table −
mysql> create table DemoTable1523 -> ( -> Id int, -> Value int -> ); Query OK, 0 rows affected (0.76 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1523 values(1,56); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1523 values(2,78); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1523 values(1,34); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1523 values(2,45); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1523 values(1,99); Query OK, 1 row affected (0.10 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1523;
This will produce the following output −
+------+-------+ | Id | Value | +------+-------+ | 1 | 56 | | 2 | 78 | | 1 | 34 | | 2 | 45 | | 1 | 99 | +------+-------+ 5 rows in set (0.00 sec)
Following is the query to match the elements of array. Here, we are selecting id with matching values 34, 99, and 56 −
mysql> select Id from DemoTable1523
-> where Value IN ('34','99','56')
-> group by Id
-> having count(*)=3;This will produce the following output −
+------+ | Id | +------+ | 1 | +------+ 1 row in set (0.00 sec)
