select * from contacts where id in (select cpk from mapping where gpk = 'MY-VARIABLE-HERE')

在Android中查询但在运行时失败.
当我使用静态变量运行它时,它可以工作并提供数据但是当我尝试使用选择args时它会失败.

到目前为止,我已经尝试过这些：

1)Cursor cursor = myDataBase.rawQuery(“select * from contacts where where in(select cpk from mapping where gpk =”“’”“？”“’”“)”,new String [] {grpName});

2)Cursor cursor = myDataBase.query(TABLE_CONTACTS,null,“id in”,new String [] {“(从映射中选择cpk,其中gpk =’”grpName“’)”},null);

3)Cursor cursor = myDataBase.rawQuery(“select * from contacts where where in(select cpk from mapping where gpk =？)”,new String [] {grpName});

请帮帮我…提前谢谢……
