Find integer in text data (comma separated values) with MySQL?

Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> DoubleValue varchar(20)
   -> );
Query OK, 0 rows affected (0.58 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable(DoubleValue) values('80.2,90.5,88.90');
Query OK, 1 row affected (0.44 sec)
mysql> insert into DemoTable(DoubleValue) values('78.56,45.80,88,45.6');
Query OK, 1 row affected (0.21 sec)
mysql> insert into DemoTable(DoubleValue) values('12.34,90.06,89.90');
Query OK, 1 row affected (0.11 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+----+---------------------+
| Id | DoubleValue         |
+----+---------------------+
|  1 | 80.2,90.5,88.90     |
|  2 | 78.56,45.80,88,45.6 |
|  3 | 12.34,90.06,89.90   |
+----+---------------------+
3 rows in set (0.00 sec)

Here is the query to find an integer in text data −

mysql> select *from DemoTable where DoubleValue LIKE '%80%';

This will produce the following output −

+----+---------------------+
| Id | DoubleValue         |
+----+---------------------+
|  1 | 80.2,90.5,88.90     |
|  2 | 78.56,45.80,88,45.6 |
+----+---------------------+
2 rows in set (0.00 sec)
