Select rows having more than 2 decimal places in MySQL?
To select rows with more than 2 decimal places, use SUBSTR() function from MySQL. Let us first create a table −
mysql> create table selectRows2DecimalPlacesDemo -> ( -> Amount varchar(100) -> ); Query OK, 0 rows affected (0.73 sec)
Following is the query to insert records in the table using insert command −
mysql> insert into selectRows2DecimalPlacesDemo values('234.5678');
Query OK, 1 row affected (0.17 sec)
mysql> insert into selectRows2DecimalPlacesDemo values('19.50');
Query OK, 1 row affected (0.19 sec)
mysql> insert into selectRows2DecimalPlacesDemo values('23.456');
Query OK, 1 row affected (0.17 sec)
mysql> insert into selectRows2DecimalPlacesDemo values('12.123');
Query OK, 1 row affected (0.14 sec)Following is the query to display all records from the table using select statement −
mysql> select * from selectRows2DecimalPlacesDemo;
This will produce the following output −
+----------+ | Amount | +----------+ | 234.5678 | | 19.50 | | 23.456 | | 12.123 | +----------+ 4 rows in set (0.00 sec)
Here is the query to select rows with more than two decimal places −
mysql> select *from selectRows2DecimalPlacesDemo WHERE LENGTH(SUBSTR(Amount,INSTR(Amount,"."))) >3;
This will produce the following output −
+----------+ | Amount | +----------+ | 234.5678 | | 23.456 | | 12.123 | +----------+ 3 rows in set (0.00 sec)
