UCanAccess error - net.ucanaccess.jdbc.UcanaccessSQLException: Incompatible data type at work :; in LIMIT, OFFSET or FETCH
I am new to UCanAccess and am using it instead of reinstalling Microsoft Office from 32-bit to 64-bit or Netbeans 8.0.2 from 64-bit to 32-bit.
I am running a simple program to connect to a small database and display the results from it; however I ran into the error that google only has 5 results when searching.
Here is my entire DB class:
package highscoresproj;
import java.io.File;
import java.sql.*;
public class DB
{
private Connection connection;
private PreparedStatement statement;
private ResultSet resultSet;
public DB()
{
//load driver
try
{
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
System.out.println("Driver successfully loaded");
} catch (ClassNotFoundException c)
{
System.out.println("Unable to load driver\n" + c);
}
//connect to database
try
{
connection = DriverManager.getConnection("jdbc:ucanaccess://"+ getDatabaseLocation("HighScores.accdb")+ ";showschema=true");
System.out.println("Connection successful");
} catch (SQLException e)
{
System.out.println("Unable to connect\n" + e);
}
}
public ResultSet query(String stmt) throws SQLException
{
statement = connection.prepareStatement(stmt);
resultSet = statement.executeQuery();
return resultSet;
}
public void update(String update) throws SQLException
{
statement = connection.prepareStatement(update);
statement.executeUpdate();
statement.close();
}
public static String getDatabaseLocation(String relativePath)
{
File dbFile = new File(relativePath);
String path = dbFile.getAbsolutePath();
path = path.replaceAll("\\\\", "/");
System.out.println("DB Full path:\t" + path);
return path;
}
}
And the method that runs when I click the button to display the top scores:
private void btnDisplayMaxActionPerformed(java.awt.event.ActionEvent evt)
{
try
{
res = db.query("SELECT TOP Username, Score FROM tblUser INNER JOIN tblScores ON UserID = ID");
}
catch (SQLException ex)
{
System.out.println("An error occured. Error Message:\n" + ex);
}
}
When I run the program and click the button, I get the following output:
run:
Driver successfully loaded
DB Full path: C:/Users/Aaron/Documents/Somerset College/IT/Java Book/Excersises/P148 Ex5/HighScoresProj/HighScores.accdb
Connection successful
An error occured. Error Message:
net.ucanaccess.jdbc.UcanaccessSQLException: incompatible data type in operation: ; in LIMIT, OFFSET or FETCH
BUILD SUCCESSFUL (total time: 11 seconds)
Please forgive me if this is a very simple error, but I couldn't find it anywhere, especially mentioning it. Thank!
