Unable to clear batch for prepared statement

To clear a batch for a prepared statement, you can use the `clearBatch` method provided by the `PreparedStatement` class in Java. Here is an example of how you can clear a batch:

try {
    // Create a connection and prepared statement
    Connection conn = DriverManager.getConnection(url, username, password);
    PreparedStatement pstmt = conn.prepareStatement("INSERT INTO my_table (column1, column2) VALUES (?, ?)");

    // Add statements to the batch
    pstmt.setString(1, "Value1");
    pstmt.setString(2, "Value2");
    pstmt.addBatch();

    pstmt.setString(1, "Value3");
    pstmt.setString(2, "Value4");
    pstmt.addBatch();

    // Clear the batch
    pstmt.clearBatch();

    // Execute the batch
    int[] updateCounts = pstmt.executeBatch();

    // Handle the update counts
    for (int count : updateCounts) {
        // Process each count
    }

    // Close the prepared statement and connection
    pstmt.close();
    conn.close();
} catch (SQLException e) {
    // Handle any errors
}

In this example, the `clearBatch` method is called after adding statements to the batch using the `addBatch` method. This clears any previously added statements in the batch.
