加入2個查詢SQL +的ColdFusion

Question

有兩個查詢，不能讓他們正常工作，他們的最終產品給人重複的項目，這裏是查詢：

1查詢

<cfquery name="get_partner_all" datasource="#dsn#"> 
    SELECT 
     C.COMPANY_ID, 
     C.FULLNAME, 
     CP.MOBILTEL, 
     CP.MOBIL_CODE, 
     CP.IMCAT_ID, 
     CP.COMPANY_PARTNER_TEL, 
     CP.COMPANY_PARTNER_TELCODE, 
     CP.COMPANY_PARTNER_TEL_EXT, 
     CP.MISSION, 
     CP.DEPARTMENT, 
     CP.TITLE, 
     CP.COMPANY_PARTNER_SURNAME, 
     CP.COMPANY_PARTNER_NAME, 
     CP.PARTNER_ID, 
     CP.COMPANY_PARTNER_EMAIL, 
     CP.HOMEPAGE, 
     CP.COUNTY, 
     CP.COUNTRY, 
     CP.COMPANY_PARTNER_ADDRESS, 
     CP.COMPANY_PARTNER_FAX, 
     CP.RECORD_DATE, 
     CP.MEMBER_CODE, 
     CC.COMPANYCAT 
     <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     ,CCD.SITE_DOMAIN 
     </cfif> 
    FROM 
     COMPANY_PARTNER CP, 
     COMPANY C, 
     COMPANY_CAT CC 
     <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     ,COMPANY_CONSUMER_DOMAINS CCD 
     </cfif> 
    WHERE 
     C.COMPANY_ID = CP.COMPANY_ID 
     AND C.COMPANYCAT_ID = CC.COMPANYCAT_ID  
    <cfif isDefined('attributes.search_status') and len(attributes.search_status)> 
     AND CP.COMPANY_PARTNER_STATUS = <cfqueryparam cfsqltype="cf_sql_integer" value="#attributes.search_status#"> 
    </cfif> 
    <cfelseif isDefined("attributes.comp_cat") and len(attributes.comp_cat)> 
     AND C.COMPANYCAT_ID = <cfqueryparam cfsqltype="cf_sql_integer" value="#attributes.comp_cat#"> 
    </cfif> 
    <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     AND CP.PARTNER_ID = CCD.PARTNER_ID 
     AND CCD.SITE_DOMAIN = 'www.projedepo.com' 
    </cfif> 
</cfquery> 

第二查詢：

<cfquery name="get_money" datasource="#dsn2#"> 
    SELECT BAKIYE,BORC,ALACAK FROM COMPANY_REMAINDER_MONEY WHERE COMPANY_ID = #company_id# 
</cfquery> 

當我嘗試以限定例如C.COMPANY_ID = CRM.COMPANY_ID它SH ows一些重複的項目，我知道我應該使用像JOIN和其他的東西，但不知道該怎麼做:)需要幫助，並感謝大家的幫助！

這裏的連接查詢，仍反覆變量：

<cfquery name="get_partner_all" datasource="#dsn#"> 
    SELECT DISTINCT 
     C.COMPANY_ID, 
     C.FULLNAME, 
     CP.MOBILTEL, 
     CP.MOBIL_CODE, 
     CP.IMCAT_ID, 
     CP.COMPANY_PARTNER_TEL, 
     CP.COMPANY_PARTNER_TELCODE, 
     CP.COMPANY_PARTNER_TEL_EXT, 
     CP.MISSION, 
     CP.DEPARTMENT, 
     CP.TITLE, 
     CP.COMPANY_PARTNER_SURNAME, 
     CP.COMPANY_PARTNER_NAME, 
     CP.PARTNER_ID, 
     CP.COMPANY_PARTNER_EMAIL, 
     CP.HOMEPAGE, 
     CP.COUNTY, 
     CP.COUNTRY, 
     CP.COMPANY_PARTNER_ADDRESS, 
     CP.COMPANY_PARTNER_FAX, 
     CP.RECORD_DATE, 
     CP.MEMBER_CODE, 
     CC.COMPANYCAT, 
     CRM.* 
     <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     ,CCD.SITE_DOMAIN 
     </cfif> 
    FROM 
     COMPANY_PARTNER CP, 
     COMPANY C, 
     COMPANY_CAT CC, 
     #dsn2_alias#.COMPANY_REMAINDER_MONEY CRM 
     <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     ,COMPANY_CONSUMER_DOMAINS CCD 
     </cfif> 
    WHERE 
     C.COMPANY_ID = CP.COMPANY_ID 
     AND C.COMPANYCAT_ID = CC.COMPANYCAT_ID 
     AND C.COMPANY_ID=CRM.COMPANY_ID 
    <cfif isDefined('attributes.search_status') and len(attributes.search_status)> 
     AND CP.COMPANY_PARTNER_STATUS = <cfqueryparam cfsqltype="cf_sql_integer" value="#attributes.search_status#"> 
    </cfif>  
    <cfif isDefined("attributes.cpid") and len(attributes.cpid)> 
     AND C.COMPANY_ID = <cfqueryparam cfsqltype="cf_sql_integer" value="#attributes.cpid#"> 
    <cfelseif isDefined("attributes.comp_cat") and len(attributes.comp_cat)> 
     AND C.COMPANYCAT_ID = <cfqueryparam cfsqltype="cf_sql_integer" value="#attributes.comp_cat#"> 
    </cfif> 
    <cfif isdefined('attributes.report_sort') and attributes.report_sort is 2> 
     AND CP.PARTNER_ID = CCD.PARTNER_ID 
     AND CCD.SITE_DOMAIN = 'www.projedepo.com' 
    </cfif> 
</cfquery> 

Answer 1

查詢沒有錯，它只顯示了COMPANY_PARTNER和COMPANY_CONSUMER_DOMAINS的所有（有效）組合。如果你想，你可以在結尾處添加一個ORDER BY：

ORDER BY C.COMPANY_ID, 
     CP.PARTNER_ID, 
     CRM.DOMAINID   --- some field in table CRM 

或

ORDER BY C.COMPANY_ID, 
     CRM.DOMAINID   --- some field in table CRM 
     CP.PARTNER_ID, 

或任何其他命令你喜歡​​，說：

ORDER BY C.COMPANY_NAME 
     C.COMPANY_ID, 
     CP.COUNTRY, 
     CP.COUNTY, 
     CP.TITLE, 
     CP.PARTNER_ID, 

---

我見此查詢可以顯示的其他兩種方式（其他可能有趣的數據）：

變化（在SELECT列表）CRM.*成Count(*) AS ConsumerDomainsCount

和在末尾添加一個GROUP BY CP.COMPANY_ID, CP.PARTNER_ID。

鏡像操作，GROUP BY CRM.COMPANY_ID, CRM.DOMAINID和刪除任何CP.*更改SELECT列表，只保留Count(*) AS PartnersCount

---

如果使用GROUP BY，你也可以使用其他聚合函數，如SUM()，AVG()，MIN() ，MAX()如果你有可以添加（數字字段）或比較（如日期）的字段。

Answer 2

這是因爲使用DISTINCT關鍵字一樣簡單？

<cfquery name="get_money" datasource="#dsn2#"> 
    SELECT DISTINCT COL1, COL2 ... FROM ... 
</cfquery> 

另外 - 您應該使用<cfqueryparam />以避免SQL注入漏洞。
