Getting [SQLITE_BUSY] database file is locked with select statements

There should be only ONE connection with your application. you can use this to ensure.

public class SqliteHelper {
private static Connection c = null;
public static Connection getConn() throws Exception {
    if(c == null){
    Class.forName("org.sqlite.JDBC");
    c = DriverManager.getConnection("jdbc:sqlite:D:/test.db");
    }
    return c;
    }
}

After some googling I found that it is a bad practice to use multiple connections when connecting to SQLite. See

Set your poolsize maxactive to 1 and try out.


Note also that this may happen if you accidentally forget to close your connection:

Connection connection;
try {
  Statement statement = connection.createStatement();
  ResultSet resultSet = statement.executeQuery(QUERY);
  if (resultSet.next()) { /* do something */ }
catch (SQLException e) { /* handle exception */ }
finally {
  if (connection != null) {
    try {
      connection.close(); // <-- This is important
    } catch (SQLException e) {
      /* handle exception */
    }
  }
}

While the first database connection may work well once the server is started, subsequent queries may not, depending on how the connection pool is configured.
