android - SQLite 中 "not equal"的语法是什么？

Question

 Cursor findNormalItems = db.query("items", columns, "type=?", 
                                   new String[] { "onSale" });

我想返回指向非 onSale 的光标，我应该改变什么？谢谢!

来自 the official documentation :

The non-equals operator can be either != or <>

所以你的代码变成了:

Cursor findNormalItems = db.query("items", columns, "type != ?", 
                                  new String[] { "onSale" });
