Question

怎么写

select * from customerdetails where locality = " something"

以形式

"Select * from customerdetails where locality =?" + locality + ";";

在这种情况下， lacality是可变的任何人都可以请解决我的问题提前致谢

Answer 1

Cursor c = db.query("customerdetails", null, "locality =?", new String[]{locality}, null, null, null);

或者您可以使用原始查询，例如

db.rawQuery("Select * from customerdetails where locality = ? ", new String[]{locality});
