JDBC returns an empty ResultSet (rs.isBeforeFirst() == true) although the table isn't empty

Question

I am trying to complete a DB access method for my Web Service. The service and the DB access methods work fine for all other tables in the DB, but this one particular method

Answer 1

isBeforeFirst() returns true if the next call to next() will put the cursor on the first row of the ResultSet. In other words, any successful query that has data, once executed, will produce a ResultSet with isBeforeFirst() returning true.

Just remove that block from your code, and have the rs.next() loop deal with potentially empty ResultSets:

try
{
    Class.forName("org.sqlite.JDBC");
    c = DriverManager.getConnection("jdbc:sqlite:lineappDB.db");
    c.setAutoCommit(false);
    System.out.println("Opened database successfully");
    stmt = c.createStatement();
    String query = String.format("SELECT * FROM VIDEOS");

    result = new Object[6];
    ResultSet rs = stmt.executeQuery(query);
    while (rs.next())
    {
        result[0] = rs.getInt(1);
        result[1] = rs.getString(2);
        result[2] = rs.getString(3);
        result[3] = rs.getString(4);
        result[4] = rs.getString(5);
        result[5] = rs.getInt(6);
    }
}
