Enviroment: Android Database: SQLite based
我有一个数据库,其数据库包括用户详情,如标识、口号、名称、国名。 我的问题是制造疑问,检查日志和口号[如此选择的查询],并且允许或不进行。
public void logineSelector(String log, String pass){
String[] kolumny = new String[]{colLogin, colPassword};
Cursor cursor= sqLiteDatabase.query(Usr_TABLE, kolumny, pass, null, null, null, null);
}
但是,整个方案都给我带来好处:
Fatal Exception: Main
Java.lang.IllegalStateException: Could not execute method of the activity
.....
是否有任何建议要做?
You re not calling the query method with the correct parameters. Check the javadoc.
如果你试图用你输入该方法的标志/密码找到用户,你可能想做这样的事情:
Cursor cursor = sqLiteDatabase.query(Usr_TABLE, kolumny,USER_COL+"= ? and "+PASS_COL + "= ?", new String[]{log,pass},null,null,null);
