遇到\语法错误 - java derby

Question

我正在尝试执行此操作：

    String qu = "INSERT INTO CLIENT(name,surname,pin,address,salary) VALUES ("
    + "'" + tempName + "',"
    + "'" + tempSurname+ "'," 
    + tempPin
    + "'" + tempAddress + "',"
    + tempMoney
    + ")";

但我得到了这个：

Exception at execQuery:dataHandlerSyntax error: Encountered "\'" at line 1, column 83.

你能告诉我我做错了什么吗？ Pin是长变量，金钱是双变量。
