I have a database order
with price
and deposit
fields set to float type. I am also implemeting a java gui to search the order, the problem is when I try to search for the orders in the database I dont find anything because it saves price=55.0 when I convert from string to float and in the database it saves as 55. What is the problem?
what type should I use to represent currency from the two sides, java side and mysql side?
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try{
//collect arguments
String category = this.jTextField8.getText();
String pattern=this.jTextArea1.getText();
String color=this.jTextArea2.getText();
float price = Float.valueOf(this.jTextField14.getText()).floatValue();
float deposit = Float.valueOf(this.jTextField15.getText()).floatValue();
//create new order
int row=this.customerSelectedRow;
Order newOrder=new order(this.customerModel.dataVector.get(row),category,pattern,color,price,deposit);
newOrder.search();
//refresh
this.jDialogNewOrder.setVisible(false);
}catch(Exception e){
System.err.println (" Error message: " + e.getMessage ());
}
}
here is the code for the search method
try {
s = c.conn.prepareStatement("SELECT id FROM `"+this.table+
"` WHERE customerId=? AND category=? and pattern=? and color=? and deposit=? and price=?");
s.setInt(1,this.customer.getId());
s.setString (2, this.category);
s.setString (3, this.pattern);
s.setString (4, this.color);
s.setFloat(5,this.deposit);
s.setFloat(6,this.price);
System.err.println(s.toString());
ResultSet res = s.executeQuery();
System.out.println("printing ids :");
while (res.next()) {
int i = res.getInt(1);
//assigning the correct id to the inserted customer
this.id=i;
System.out.println("id" + "=" + i);
}
} catch (SQLException e) {
System.err.println ("find id Error message: " + e.getMessage ());
System.err.println ("find id Error number: " + e.getErrorCode ());
