嗨,我試圖讓SQL從哪個用戶已經從列表框中 繼承人我的代碼選擇了一個表中選擇消息「FROM子句語法錯誤」 activity := cmbActivity.Text; //this is where the user selects a table to choose from
qryStudents.SQL.Text := 'SELECT * FROM :activity WHERE CompN
我有2個實體組和用戶。 1'組'有一組用戶,1'用戶'有一組組。我想在橋牌桌上 Group: GroupID, name
User: UserID, name
GroupUser (bridge table): GroupID, UserID
刪除記錄目前我有 var query = from u in context.User
from g in u.Group
