db.close(); 

錯誤在哪裏？

Answer 1

我猜測用戶名是varchar類型的？那麼你應該在它周圍添加單引號。同樣的日期。

stmt.executeUpdate("INSERT INTO playsms_tblUser(parent_uid, status, username, password, token, enable_webservices, credit, datetime_timezone, language_module, register_datetime, lastupdate_datetime)" 
+ "VALUES (1, 4, '"+user+"', MD5("+password+"), MD5("+password+"), 1, "+initialCredit+", +0100, en_US, '"+dataStr+"', '"+dataStr+"')"); 

db.close（）;
