MySQL query to find all rows where ID is divisible by 4?
Let us first create a table with one of the column as ID −
mysql> create table DemoTable ( ID int, StudentName varchar(10), CountryName varchar(20) ); Query OK, 0 rows affected (0.70 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(0,'David','AUS'); Query OK, 1 row affected (0.24 sec) mysql> insert into DemoTable values(3,'Chris','UK'); Query OK, 1 row affected (0.27 sec) mysql> insert into DemoTable values(8,'Carol','US'); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable values(9,'Sam','US'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values(12,'Robert','UK'); Query OK, 1 row affected (0.27 sec) mysql> insert into DemoTable values(10,'Mike','AUS'); Query OK, 1 row affected (0.17 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
+------+-------------+-------------+ | ID | StudentName | CountryName | +------+-------------+-------------+ | 0 | David | AUS | | 3 | Chris | UK | | 8 | Carol | US | | 9 | Sam | US | | 12 | Robert | UK | | 10 | Mike | AUS | +------+-------------+-------------+ 6 rows in set (0.00 sec)
Following is the query to find all rows where ID is divisible by 4 −
mysql> select *from DemoTable where (ID%4)=0;
Output
+------+-------------+-------------+ | ID | StudentName | CountryName | +------+-------------+-------------+ | 0 | David | AUS | | 8 | Carol | US | | 12 | Robert | UK | +------+-------------+-------------+ 3 rows in set (0.30 sec)
