How to make MySQL result set the same as specified?
For this, use MySQL FIND_IN_SET(). Let us first create a table −
mysql> create table DemoTable1563 -> ( -> StudentId int, -> StudentName varchar(20) -> ); Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1563 values(1001,'Chris'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1563 values(1010,'Bob'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable1563 values(1005,'Chris'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable1563 values(1015,'David'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable1563 values(1030,'Mike'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable1563 values(1020,'Sam'); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1563;
This will produce the following output −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 1001 | Chris | | 1010 | Bob | | 1005 | Chris | | 1015 | David | | 1030 | Mike | | 1020 | Sam | +-----------+-------------+ 6 rows in set (0.00 sec)
Here is the query to form MySQL result set the same as specified −
mysql> select * from DemoTable1563 -> where StudentId IN(1001,1030,1010,1020) -> order by find_in_set(StudentId,'1001,1030,1010,1020');
This will produce the following output −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 1001 | Chris | | 1030 | Mike | | 1010 | Bob | | 1020 | Sam | +-----------+-------------+ 4 rows in set (0.00 sec)
