For this, use FLOOR() function. Here, we will be fetching records like 12.00, 35.00, etc. from a list with records like 5.23, 8.76, 12.00, 22.68, etc. Let us first create a table −
mysql> create table DemoTable ( Value DECIMAL(4,2) ); Query OK, 0 rows affected (0.53 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(54.20); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values(55.0); Query OK, 1 row affected (0.24 sec) mysql> insert into DemoTable values(7.8); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values(9.0); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values(9.2); Query OK, 1 row affected (0.21 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------+ | Value | +-------+ | 54.20 | | 55.00 | | 7.80 | | 9.00 | | 9.20 | +-------+ 5 rows in set (0.00 sec)
Following is the query to fetch records where decimal is a whole number −
mysql> select *from DemoTable where Value=floor(Value);
This will produce the following output −
+-------+ | Value | +-------+ | 55.00 | | 9.00 | +-------+ 2 rows in set (0.02 sec)
