Android的SQLite的插入或更新 [英] Android SQLite Insert or Update

问题描述

由于可以在文档中看到的语法，使插入或更新为：插入或更换成＆LT;表＆gt; （小于列＆GT;）VALUES（小于值＆GT;），我的问题是那里合并以下

as can be seen in the documentation the syntax to make insert or update is : INSERT OR REPLACE INTO <table> (<columns>) VALUES (<values>), my question is there any function that merge the following ?

public long insert (String table, String nullColumnHack, ContentValues values) 
public int update (String table, ContentValues values, String whereClause, String[] whereArgs)

或它必须用prepared SQL语句并rawQuery？

or it has to be done with a prepared SQL statement and rawQuery?

什么是最好的做法，以做到在Android中插入或更新？

What's the best practices to do an insert or update in Android?
