這上面的代碼用於PDF顯示數據庫中的列。但我所使用錯誤，同時使用選擇查詢顯示PDF柱
select * from
(select p1.PubID,p2.Publisher,p2.Title,p.name as authors
from Personal_det p,Publication_Tracker p1,Publication_det p2
where p.FID=p1.FID and p1.Contribution_Type='A' and p1.PubID=p2.PubID ) t1
inner join
(select p.Name as coauthors,p2.PubID,p2.Type,p2.Title,p2.PubDate
from Personal_det p,Publication_Tracker p1,Publication_det p2
where p.FID=p1.FID and p1.Contribution_Type='C' and p1.PubID=p2.PubID ) t2
on t1.PubID = t2.PubID
上述查詢具有四行但是在PDF中顯示它只顯示one行。如何解決？任何幫助讚賞。
行'PdfPTable tabl11 =新PdfPTable（8）;'創建一個8列的表格，但您的評論說，該數據庫有4列。此外，你說「四列，但在PDF中顯示時只顯示一行」。列數不影響行數，您需要更好地解釋問題。什麼是「單元」變量。請通過刪除不屬於問題一部分的代碼（單元格，段落，時間，FontFactory等）來更新上述內容。另外，因爲我們沒有數據庫，所以如果你給了我們一些像數組數組一樣可重複的東西，它將會有所幫助。 –
您不關閉sql連接cn19和SqlDataReader rdr11。此外，這兩個查詢在條件有所不同。這有效嗎？ – ray
