Question

Visual Studio 2010을 사용하여 C#에서 프로그램을 작성하고 .sdf 파일에서 데이터를 검색 할 때 오류가 발생합니다.

private void BasicSearch_button_Click(object sender, EventArgs e)

어떤 도움이 필요합니까?

미리 감사드립니다. 난 당신이 의미 의심

... INNER JOIN 
PhotoON PhotoTags.PhotoID = Photo.PhotoID ... 

:

Answer 1

나는이 문제를 의심

... INNER JOIN 
Photo ON PhotoTags.PhotoID = Photo.PhotoID ... 

주 Photo와 ON 사이의 공간. 나는 당신이 당신의 질의를 재 포맷하여 의심의 여지가 없도록 솔직하게 말할 수있을 것이라고 생각합니다 ...
