Question

这让我很疯狂，但无法让它发挥作用。

我想将以下内容粘贴到R。

中的SQL查询中

UKWinnersID<-c("'1WKX6'", "'ULTY8'", "'JNZX0'", "'8J4D8'", 
"'KZJAJ0'", "'W8BH47'", "'CP8RPW9'", "'52TD5'", "'TLKV4'")



sqlQuery(myConn, paste("SELECT TOP 10000 [AxiomaDate]
                      ,[RiskModelID] ,[AxiomaID],[Factor1],[Factor2],[Factor3]
                      FROM [PortfolioAnalytics].[Data_Axioma]
                     Where  AxiomaID IN (",(paste(UKWinnersID, collapse = ","),")")))

我现在正在使用粘贴功能，但似乎无法正常工作。有人有个主意吗？最后一行的输入将是这样的（数据存储在a中）以使查询起作用..

AxiomaID IN ('1WKX6', 'ULTY8', 'JNZX0', '8J4D8', 
'KZJAJ0', 'W8BH47', 'CP8RPW9', '52TD5', 'TLKV4')

当前输出

sqlQuery等AxiomaID IN（＆＃39; 1WKX6＆＃39;，＆＃39; ULTY8＆＃39;，＆＃39; JNZX0＆＃39;，＆＃39; 8J4D8＆＃39;，＆＃39; KZJAJ0＆＃39;，＆＃39; W8BH47＆＃39;，＆＃39; CP8RPW9＆＃39;，＆＃39; 52TD5＆＃39;，＆＃39; TLKV4＆＃39;）＆＃39;＆＃34;

基本上我想删除此粘贴中的最后两个字符，这是一个＆＃39;和＆＃34;。

我无法重新创建您的确切输出。尝试以下方法;它产生了我期望的SQL代码。

UKWinnersID<-c("'1WKX6'", "'ULTY8'", "'JNZX0'", "'8J4D8'", 
               "'KZJAJ0'", "'W8BH47'", "'CP8RPW9'", "'52TD5'", "'TLKV4'")

sqlQuery(myConn, paste("SELECT TOP 10000 [AxiomaDate]
                      ,[RiskModelID] ,[AxiomaID],[Factor1],[Factor2],[Factor3]
                       FROM [PortfolioAnalytics].[Data_Axioma]
                       Where  AxiomaID IN (",paste(UKWinnersID, collapse = ","),")"))

我推荐了类似问题的解决方案。见Pasting Values in SQL Query through R

您可以尝试使用查询值定义字符变量。然后你可以调用函数InsertListInQuery传递查询和向量作为参数，如下所示：

UKWinnersID<-c("'1WKX6'", "'ULTY8'", "'JNZX0'", "'8J4D8'", 
               "'KZJAJ0'", "'W8BH47'", "'CP8RPW9'", "'52TD5'", "'TLKV4'")

query <- "SELECT TOP 10000 [AxiomaDate]
                      ,[RiskModelID] ,[AxiomaID],[Factor1],[Factor2],[Factor3]
                      FROM [PortfolioAnalytics].[Data_Axioma]
                     Where  AxiomaID IN ()"

SQLQuery <- InsertListInQuery(query, UKWinnersID)

SQLQuery
[1] "SELECT TOP 10000 [AxiomaDate]\n,[RiskModelID] ,[AxiomaID],[Factor1],[Factor2],[Factor3]\nFROM [PortfolioAnalytics].[Data_Axioma]\nWhere  AxiomaID IN ( '1WKX6' , 'ULTY8' , 'JNZX0' , '8J4D8' , 'KZJAJ0' , 'W8BH47' , 'CP8RPW9' , '52TD5' ,'TLKV4')"

我希望它有所帮助。
