Using MySQL IN() for some column values with underscore

Let us first create a table −

mysql> create table DemoTable1363
    -> (
    -> StudentId varchar(20)
    -> );
Query OK, 0 rows affected (0.57 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1363 values('901');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable1363 values('702');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1363 values('901_John_Doe');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1363 values('1001_Carol_Taylor');
Query OK, 1 row affected (0.26 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1363;

This will produce the following output −

+-------------------+
| StudentId         |
+-------------------+
| 901               |
| 702               |
| 901_John_Doe      |
| 1001_Carol_Taylor |
+-------------------+
4 rows in set (0.00 sec)

Here is the MySQL query to implement IN() −

mysql> select * from DemoTable1363 where StudentId IN('702','1001');

This will produce the following output −

+-----------+
| StudentId |
+-----------+
| 702       |
+-----------+
1 row in set (0.00 sec)
