我正在研究 APPCELERATOR TITANIUM。
我正在使用一个数据库，其中奇怪的是一些 sql 查询无法正常工作，例如:
db.execute("SELECT Location_Diners.Dining_Time,Location_Diners.First_Name,Location_Diners.Last_Name,Location_Diners.PartySize,Location_Diners.Diner_ID,Location_Diners.DinerStatusColor_ID,Location_Diners.Notes,Location_Diners.Diner_ID,Location_SeatedDiners.Table_ID FROM Location_Diners LEFT JOIN Location_SeatedDiners ON Location_Diners.Diner_ID=Location_SeatedDiners.Diner_ID");
这是我遇到的错误，请帮帮我......

非常感谢任何帮助................................
最佳答案
嘿 Prateek 我认为你应该使用 LEFT OUTER JOIN。 检查这个，
What joins does SQLite support?
根据这个 LEFT JOIN = LEFT OUTER JOIN 但 SQLite3 支持关键字 LEFT OUTER JOIN。
关于sql - 在appcelerator titanium sql left join中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8585900/
