MySQL query to find a value in a set of values separated by comma in a custom variable
For this, use FIND_IN_SET() in MySQL and use the value from a custom variable. Let us first create a −
mysql> create table DemoTable1411 -> ( -> Value int -> ) -> ; Query OK, 0 rows affected (0.50 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1411 values(10); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1411 values(50); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1411 values(60); Query OK, 1 row affected (0.08 sec)
Display all records from the table using select −
mysql> select * from DemoTable1411;
This will produce the following output −
+-------+ | Value | +-------+ | 10 | | 50 | | 60 | +-------+ 3 rows in set (0.00 sec)
Following is the query to find a value in set of other values. Here, we have set a custom variable first, which is used for the FIND_IN_SET() method −
mysql> set @setOfValues:='70,50,100'; Query OK, 0 rows affected (0.00 sec) mysql> select * from DemoTable1411 -> where find_in_set(Value,@setOfValues);
This will produce the following output −
+-------+ | Value | +-------+ | 50 | +-------+ 1 row in set (0.00 sec)
