MySQL Database Selection Error
When retrieving data from a MySQL database hosted on GoDaddy, users may encounter a "No Database selected" error. This issue typically arises when the database URL lacks the database name specification.
Solution:
The database URL used in the JDBC connection should include the database name. This is typically done by appending "/DBNAME" to the original URL. For example:
<code class="java">String URL = "jdbc:mysql://localhost:3306/my_database";</code>
In this case, "my_database" is the name of the database being accessed.
Original Code with Modification:
Integrating the database name into the original code:
<code class="java">public static void main(String[] args) { Connection conn = null; Statement stmt = null; try { // ... (code remains the same) // Modify the database URL to include the database name String URL = "jdbc:mysql://localhost:3306/my_database"; // STEP 3: Open a connection System.out.println("Connecting to database..."); conn = DriverManager.getConnection(URL, USER, PASS); // ... (remaining code remains the same) } }</code>
By incorporating the database name into the URL, the JDBC connection can successfully identify the database to access and eliminate the "No database selected" error.
