SQLite Titanium 语法错误

以下 SQL 代码在 SQLite 管理器和其他 SQLite 系统中运行良好，但是当我在 Titanium 中使用它时，我得到一个Uncaught SyntaxError: Unexpected String".如果我的语法错误，应该如何为 Titanium 编码?

The following SQL code works fine in SQLite Manager and in other SQLite systems, however when I use it in Titanium I get an "Uncaught SyntaxError: Unexpected String." If my syntax is wrong, how should it be coded for Titanium?

    SELECT Date, Content
    FROM MYDATABASE
    WHERE strftime('%m%d', Date) = strftime('%m%d', date('now'))

推荐答案

您是否将您的表称为 MYDATABASE?您是否正在逐步调试调试器并确认 var rs = db.execute("SELECT Date, Content FROM MYDATABASE WHERE strftime('%m%d', date) = strftime('%m%d', date('现在'))");

Did you call your table MYDATABASE? Are you stepping through the debugger and confirming that var rs = db.execute("SELECT Date, Content FROM MYDATABASE WHERE strftime('%m%d', date) = strftime('%m%d', date('now')) ");

在我的 Titanium Mobile 项目中，我首先定义了数据库:

In my Titanium Mobile project I first defined the database:

var db = Ti.Database.open('myDb');
db.execute('CREATE TABLE IF NOT EXISTS [MYDATABASE](id INTEGER PRIMARY KEY AUTOINCREMENT, Date DATE, Content TEXT)');
db.close();

然后我从函数调用中执行了这段代码

I then executed this code from a function call

var db = Ti.Database.open('myDb');
var myresult = db.execute("INSERT INTO MYDATABASE(Date, Content) VALUES (date('now'), '12345')");
myresult = db.execute("SELECT Date, Content FROM MYDATABASE WHERE strftime('%m%d', Date) = strftime('%m%s', date('now')) ");
Ti.API.info('myresult: ' + myresult.fieldByName('Content'));

此代码在调试窗口中成功返回 myresult: 12345.您可能需要向我们提供源代码的重要部分，以便我们可以看到代码的流程.给我们碎片是行不通的.

This code returns myresult: 12345 in the debug window successfully for me. You probably need to provide us with a significant part of the source code so we can see the flow of the code. Giving us pieces isn't working.

不幸的是，我不得不在另一台计算机上进行测试，希望在这里重新输入不会出错"

Unfortunately, I had to test this from another computer and hopefully didn't make any errors re-typing it here"
