HXTT ACCESS
Currency Data Type messes up the decimal digits

Hi,
We are noticing that the Currency Data Type does not work properly with the HXTT driver.

Please find the sample program attached which inserts and retrieves values from a Currency Field. Notice that the decimal digits are fluctuating for some reason.

import java.math.BigDecimal;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;

public class testPreparedStatementAccess
{
public static void main(String argv[])
{

try
{
Class.forName("com.hxtt.sql.access.AccessDriver").newInstance();
Connection connection = DriverManager.getConnection("jdbc:access:/C:\\Access\\DataTypes.accdb");


String createTable = "Drop table if exists [CurrencyTestTable]";
Statement stmt = connection.createStatement();
stmt.execute(createTable);
connection.commit();
stmt.close();

createTable = "CREATE TABLE [CurrencyTestTable] ([MoneyField] OTHER(Currency) )";
stmt = connection.createStatement();
stmt.execute(createTable);
connection.commit();
stmt.close();

PreparedStatement ps = null;
String sql = "INSERT INTO [CurrencyTestTable] (MoneyField ) VALUES ( ? )";
ps = connection.prepareStatement(sql);

String[] value = {"15624372223167.8413","63478118456360.54","56881394037433.556","77005005610025.1372","15624372223167.8013"};
BigDecimal currencyValue[] = new BigDecimal[value.length];
for (int i=0 ; i < currencyValue.length ; i++) {
currencyValue[i]= new BigDecimal(value[i]);

System.out.println("Stored currency value is : "+ currencyValue[i]);
ps.setBigDecimal(1, currencyValue[i]);
ps.execute();
}
ps.close();

System.out.println("====================================");
String select = "Select MoneyField from CurrencyTestTable ";
ResultSet rs = connection.createStatement().executeQuery(select);

while (rs.next()) {
System.out.println("Retrieved currency value is : "+ rs.getObject(1));
}
rs.close();
connection.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}


This results in the output ::::


Stored currency value is : 15624372223167.8413
Stored currency value is : 63478118456360.54
Stored currency value is : 56881394037433.556
Stored currency value is : 77005005610025.1372
Stored currency value is : 15624372223167.8013
====================================
Retrieved currency value is : 15624372223167.8438
Retrieved currency value is : 63478118456360.5391
Retrieved currency value is : 56881394037433.5547
Retrieved currency value is : 77005005610025.1406
Retrieved currency value is : 15624372223167.8008



A similar test against MSSQL MONEY Data Type field returns the following results.

Stored currency value is : 15624372223167.8413
Stored currency value is : 63478118456360.54
Stored currency value is : 56881394037433.556
Stored currency value is : 77005005610025.1372
Stored currency value is : 15624372223167.8013
====================================
Retrieved currency value is : 15624372223167.8413
Retrieved currency value is : 63478118456360.5400
Retrieved currency value is : 56881394037433.5560
Retrieved currency value is : 77005005610025.1372
Retrieved currency value is : 15624372223167.8013


Please let me know in case I've overlooked anything. Thank you.
