Question

我正在使用cordova 1.9开发一个phonegap应用程序。
我在这个语句中有语法错误：

db.executeSql('UPDATE Reminder SET Reminder.reminderName ="'+ reminder_name + '", Reminder.reminderDescription = "' + description +'", Reminder.cellId='+ 1 +',  Reminder.timetableId ='+1+', Reminder.reminderDeadline ="' + deadline +'" WHERE Reminder.RminId = "'+reminderId+'" ');

所以，我想知道我做错了什么？

Answer 1

看起来你的单引号和双引号错误而且凌乱试试这个：

    db.executeSql("UPDATE Reminder SET Reminder.reminderName = "
            + reminder_name + ", Reminder.reminderDescription = "
            + description + ", Reminder.cellId = " + 1
            + ",  Reminder.timetableId = " + 1
            + ", Reminder.reminderDeadline = " + deadline
            + " WHERE Reminder.RminId = " + reminderId + " ");

Answer 2

可能是你的1的问题。

如果你输入1，你应该把它放在变量中或保留引号：

db.executeSql('UPDATE Reminder SET Reminder.reminderName ="'+ reminder_name + '", Reminder.reminderDescription = "' + description +'", Reminder.cellId=1,  Reminder.timetableId =1, Reminder.reminderDeadline ="' + deadline +'" WHERE Reminder.RminId = "'+reminderId+'" ');

或

var cellID = 1;
var timetableID = 1;
db.executeSql('UPDATE Reminder SET Reminder.reminderName ="'+ reminder_name + '", Reminder.reminderDescription = "' + description +'", Reminder.cellId='+ cellID +',  Reminder.timetableId ='+timetableID+', Reminder.reminderDeadline ="' + deadline +'" WHERE Reminder.RminId = "'+reminderId+'" ');

Phonegap上的Sqlite错误“附近”。“：语法错误”
