ASP試圖從數據庫中轉換出來並將這兩個值相乘

Question

嗨我正在嘗試以下操作：

代碼是用ASP編寫的，輸出來自數據庫。我正在嘗試將數量和速率＃2相乘，並在返回的數據中顯示每個訂單的總數。這涉及輸出中的最後一個td。

<td align="center" height="30"><%= rowCrossHire("NLCODE") %></td> 
<td align="center" height="30"><%= rowCrossHire("QTY") %></td> 
<td align="center" height="30"><%= rowCrossHire("QTYRETD") %></td> 
<td align="center" height="30"><%= formatcurrency(rowCrossHire("RATE#1"), 2) %></td> 
<td align="center" height="30"><%= need to add "QTY" * "RATE#1" here %></td> 

還有什麼需要請讓我知道 預先感謝 大衛

Answer 1

您應該能夠選擇「數量」 *「RATE＃1」，在SQL語句中的列，用「AS columnName」別名，然後在輸出中引用columnName。

在SQL中，使用

QTY * RATE#1 as TotalColumn 

哪裏TotalColumn是你想要在你的ASP代碼使用的值。
