MySQL query to get string from one column and find its position in another column with comma separated values?
For this, use FIND_IN_SET(). Let us first create a table −
mysql> create table DemoTable1866 ( Value1 int, ListOfValues varchar(100) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1866 values(56,'78,56,98,95'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1866 values(103,'103,90,102,104'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1866 values(77,'34,45,77,78'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1866;
This will produce the following output −
+--------+----------------+ | Value1 | ListOfValues | +--------+----------------+ | 56 | 78,56,98,95 | | 103 | 103,90,102,104 | | 77 | 34,45,77,78 | +--------+----------------+ 3 rows in set (0.00 sec)
Here is the query to get string position in another column −
mysql> select Value1,ListOfValues,find_in_set(Value1,ListOfValues) as Output from DemoTable1866;
This will produce the following output −
+--------+----------------+--------+ | Value1 | ListOfValues | Output | +--------+----------------+--------+ | 56 | 78,56,98,95 | 2 | | 103 | 103,90,102,104 | 1 | | 77 | 34,45,77,78 | 3 | +--------+----------------+--------+ 3 rows in set (0.00 sec)
