How select specific rows in MySQL?
To select specific rows, use FIND_IN_SET() function in MySQL. Let us first create a table −
mysql> create table DemoTable ( ListOfValues varchar(200) ); Query OK, 0 rows affected (0.31 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('112,114,567,Java,345'); Query OK, 1 row affected (0.06 sec) mysql> insert into DemoTable values('222,214,256'); Query OK, 1 row affected (0.06 sec) mysql> insert into DemoTable values('2,567,98,C'); Query OK, 1 row affected (0.06 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------------------+ | ListOfValues | +----------------------+ | 112,114,567,Java,345 | | 222,214,256 | | 2,567,98,C | +----------------------+ 3 rows in set (0.00 sec)
Following is the query to select specific rows in MySQL −
mysql> select *from DemoTable where find_in_set('2',ListOfValues) >0;
This will produce the following output −
+--------------+ | ListOfValues | +--------------+ | 2,567,98,C | +--------------+ 1 row in set (0.03 sec)
