Why am I getting a `MySQLSyntaxErrorException` when using a prepared statement for a SELECT query?

MySQL Prepared Statement Encountering MySQLSyntaxErrorException

When executing a SELECT statement using a prepared statement, the following error may be encountered:

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?' at line 1
Copy after login

To resolve this error, it is essential to examine the code in question. In the code provided, there seems to be an issue with the line:

<code class="java">    rs = stmt.executeQuery(selectSQL);</code>
Copy after login

The error originates from the incorrect usage of executeQuery(). In this case, it should be used without the selectSQL parameter. The corrected line should be:

<code class="java">    rs = stmt.executeQuery();</code>
Copy after login

By making this change, the query will execute properly without encountering the syntax error.
