SQLite语法错误在“？”附近

Question

Simple enough; my code looks like this:

int idhash = getIdHash();
String[] args = {"runways", ""+idhash};
cursor = sqlite.rawQuery("SELECT * FROM ? WHERE idhash = ?", args);

And I see this line in logcat:

E/SQLiteLog( 9570): (1) near "?": syntax error

Where did I go wrong?

Answer 1

You can use ? only for binding literals. You cannot use it for binding identifiers such as table names. Identifiers must be in the SQL itself.

Answer 2

Maybe you can try

  Cursor cursor =  sqlite.rawQuery("SELECT * FROM runways WHERE idhash = ?", new String[]{idhash.toString()});

and it
