Give third-party access to AWS hosted MySQL
GRANT SELECT ON My_Database.* TO bi_user;


It's explained in detail here (sample code below).

Don't forget though that people with SELECT privileges can cripple a database as surely as if they had DELETE privileges by running complex reports.

Code from website:



If you want give a user read-only access to a database, you can grant to him/her only the "SELECT" privilege, so that he/she can not run any DDL statements, and any INSERT, UPDATE, or DELETE statements. The tutorial exercise gives you a good example:
&gt;cd \mysql\bin
&gt;mysql -u root -ppassword

mysql&gt; USE fyi;
Database changed

mysql&gt; CREATE TABLE links (id INTEGER, name VARCHAR(80));
Query OK, 0 rows affected (0.14 sec)

mysql&gt; INSERT INTO links VALUES (1, 'dba.fyicenter.com');
Query OK, 1 row affected (0.05 sec)

mysql&gt; CREATE USER guest IDENTIFIED BY 'other_password';
Query OK, 0 rows affected (0.24 sec)

mysql&gt; GRANT SELECT ON fyi.* TO guest;
Query OK, 0 rows affected (0.00 sec)

mysql&gt; QUIT;

&gt;mysql -u guest -pother_password

mysql&gt; use fyi;
Database changed

mysql&gt; SELECT * FROM links;
+------+-------------------+
| id   | name              |
+------+-------------------+
|    1 | dba.fyicenter.com |
+------+-------------------+
1 row in set (0.04 sec)

mysql&gt; INSERT INTO links VALUES (2, 'dev.fyicenter.com');
ERROR 1142 (42000): INSERT command denied to user
