This is my table

SQL

+-------------------+--------------+------+-----+---------+----------------+
| Field             | Type         | Null | Key | Default | Extra          |
+-------------------+--------------+------+-----+---------+----------------+
| USER_ID           | bigint(20)   | NO   | PRI | NULL    | auto_increment |
| USER_ABOUT_YOU    | varchar(255) | YES  |     | NULL    |                |
| USER_COUNTRY      | varchar(255) | YES  |     | NULL    |                |
| USER_GENDER       | varchar(255) | YES  |     | NULL    |                |
| USER_MAILING_LIST | bit(1)       | YES  |     | NULL    |                |
| USER_NAME         | varchar(255) | YES  |     | NULL    |                |
| USER_PASSWORD     | varchar(255) | YES  |     | NULL    |                |
+-------------------+--------------+------+-----+---------+----------------+

This is the query to insert data
INSERT INTO `user` (`USER_ID`, `USER_ABOUT_YOU`, `USER_COUNTRY`, `USER_GENDER`, `USER_MAILING_LIST`, `USER_NAME`, `USER_PASSWORD`) VALUES (2, 'omg', 'India', 'Female', b'1', 'test', 'test');

Solution 1

1) See MySQL reference about bit fields: http://dev.mysql.com/doc/refman/5.0/en/bit-field-literals.html[^]
2) Don't use string concatenation for building sql statement (you are exposing your app to SQLinjection), use parameters (sse: AddWithValue[^]) method.
