How to treat MySQL longtext as integer in MySQL query?

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Value longtext
   -> );
Query OK, 0 rows affected (0.94 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('778437437447488487476464644433334');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('9998888485775775757577578585');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('8888874757757757757757575675656');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('988757757574646');
Query OK, 1 row affected (0.09 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable;

This will produce the following output −

+-----------------------------------+
| Value                             |
+-----------------------------------+
| 778437437447488487476464644433334 |
| 9998888485775775757577578585      |

| 988757757574646                   |
