Can not insert data to MS Access

Question

Hi All,
I have create a table by manual in Access , in which I defined souch fields:
SORTCODE(text type),FOODNAME(text type)..., and then I use follow statement to insert value :
private DefaultTableModel model = new DefaultTableModel();
Vector collectData = new Vector(50,20);
String sqlStatement = "INSERT ������(SORTCODE,FOODNAME,MEASUREUNIT,QUANTITY,UNITPRICE,BUYDATE,SUPPLIER,BUYER,HOTELNUM,HOTELNAME,REMARK) VALUES (?,?,?,?,?,?,?,?,?,?,?)";
try
PreparedStatement insertData = dbConnection.prepareStatement(sqlStatement);
for(int i=0;i<rowsFlag;i++)
for(int j=1;j<cols;j++)
collectData.add(model.getValueAt(i,j));
insertData.setString(1,collectData.get(0).toString());
int update = insertData.executeUpdate(); //an Exception throwed
catch(Exception ex)
ex.printStackTrace();
when run the code , it always reports Access field not correct error , how to solve the problem ?

Hi Liwei,
Apart from what marych said, according to the code you posted, you are only supplying one value to your "PreparedStatement", namely:
insertData.setString(1,collectData.get(0).toString());You need to supply eleven values (in total), since your "sqlStatement" contains eleven question-mark ("?") characters.
Also note that if one of the values you supply is null, then you need to use the "setNull()" method (of "PreparedStatement") and not the "setString()" method.
Hope this helps.
Good Luck,
Avi.
