將sql php腳本轉換爲coldfusion

Question

我們有一個腳本，該腳本已經從我們的開發人員提供，用於從我們的數據庫生成暢銷書列表，但是我們需要它在coldfusion中！

是否有一個簡單的方法來轉換或將此需要完全重寫？

在此先感謝您的任何意見:-)

代碼轉換問題不容易，因爲他們被視爲懶惰留長開。所以，下面是一些引用來幫助你入門。我不是PHP專業人員，但是快速瀏覽一下你的代碼後，我認爲這個鏈接列表會給你一個良好的開端。

• CFFunction
• CFQuery
• CFArgument
• valueList()
• CFLoop
• CFif

在沒有做你的工作你，給喲利益ü有機會學習，我會提供一些示例，但不提供整個代碼，以便您瞭解您的PHP適用於CF.這也是標籤版本，而不是腳本版本。

<cffunction name = "CWgetBestSelling" ...> 
    <cfargument name = "max_products" default = "5" ...> 
    <cfargument ...> 

    <cfset var local.productQuery = ""> 
    <cfset var local.returnQuery = ""> 
    <cfset ...> 
    <cfset ...> 

    <cfquery name = "q_productQuery " datasource = "yourDatasource"> 
    SELECT 
     count(*) as prod_counter, 
     p.product_id, 
     p.product_name, 
     p.product_preview_description, 
     p.product_date_modified 
    FROM 
     cw_products p 
     INNER JOIN cw_order_skus o 
     INNER JOIN cw_skus s 
    WHERE 
      o.ordersku_sku = s.sku_id 
     AND s.sku_product_id = p.product_id 
     AND NOT p.product_on_web = 0 
     AND NOT p.product_archive = 1 
     AND NOT s.sku_on_web = 0 
    GROUP BY 
     product_id 
    ORDER BY 
     prod_counter DESC 
    LIMIT #arguments.max_products# 
    </cfquery> 

    ... 
    ... 
    ... 

    <cfreturn yourReturnVariable> 
</cffunction>
