Calculating byte values to megabyte (MB) in MySQL?
Here, we are taking BIGINT type, since it takes 8 byte signed integer. Let us first create a table with column as BIGINT type −
mysql> create table DemoTable2031 -> ( -> ByteValue bigint -> ); Query OK, 0 rows affected (1.17 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable2031 values(1048576); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable2031 values(1073741824); Query OK, 1 row affected (0.13 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable2031;
This will produce the following output −
+------------+ | ByteValue | +------------+ | 1048576 | | 1073741824 | +------------+ 2 rows in set (0.00 sec)
Here is the query to calculate bytes to Megabyte (MB) −
mysql> select (ByteValue/(1024*1024)) as MB from DemoTable2031;
This will produce the following output −
+-----------+ | MB | +-----------+ | 1.0000 | | 1024.0000 | +-----------+ 2 rows in set (0.00 sec)
