Question

I’m trying to insert a tuple into a mySQL database in the following manner.

 String insertString = "INSERT INTO listings(Seller, Title, Close_Time, Price, Condition)"
                + " VALUES('"+par.getSellerName()+"', '"+par.getItemName()+"', "
                +closetime+", "+par.getPrice()+", '"+par.getCondition()+"')";

pst = con.prepareStatement(insertString);
pst.executeUpdate();
ResultSet rs = pst.getGeneratedKeys();

but I keep getting a SQL syntax error. Strangely I don’t have a problem if I leave off Condition. In the listings table Condition is a varchar(45) and par.getCondition() returns a String length<45.

I have tried this also like:

pst = con.prepareStatement(
                    "INSERT INTO listings(Seller, Title, Close_Time, Price, Condition)"
                    + "VALUES(?,?,?,?,?)", Statement.RETURN_GENERATED_KEYS);
pst.setString(1, par.getSellerName());
        pst.setString(2, par.getItemName());
        long closeTime = getTimeMills(par.getTimeOver());
        pst.setLong(3, closeTime);
        pst.setDouble(4, par.getPrice());
        pst.setString(5, par.getCondition());
        pst = con.prepareStatement(insertString);
        pst.executeUpdate();
        ResultSet rs = pst.getGeneratedKeys();

with the same results. I’m sure that I must be doing something stupid, but I’m at a total loss. I’ve printed out the string before the insert is executed and am unable to find any syntax errors. Any help will be greatly appreciated.

Condition is a reserved word in mysql: see Reserved words for mysql

Just rename the property and it will execute fine
