Sql server Microsoft R服务器解析错误

你不能将代码从RStudio无缝地复制/粘贴到SQL Server存储过程，这真是太差劲了，但是，唉，如果不是这样的话，就不会是微软了，对吧

基本上，我在解析时会遇到非常奇怪的错误：

Error in source(revoScriptConnection) : 
  revoScriptConnection:116:111: unexpected INCOMPLETE_STRING
116: dtCumulativeResults[,c("State_Name_RAW","City_Name_MDM","County_Name_MDM","State_Name_MDM","City_Address_MDM","City_

以下是实际的代码行（包括前面的几行）：

---

请注意，脚本的大部分被指定为非Unicode字符串文字。之后的每一件事

usrOutputFile <- "' + @usrOutputFilePath + @usrOutputFileName + '"  . . .

---

usrOutputFile那么问题很有可能出现在这两行之前的几行中，我们看不到。我在前面添加了几行（这只是右括号）。错误还声明字符串未终止，但实际代码显示它已终止。例如，如果我将这些行前面的结束括号折叠到同一行上，现在，意外的不完整_字符串错误出现在同一行后面的几个字符空间中。如果您声称问题可能出现在这两行以上的过程中，则问题中除完整过程文本外的任何内容都可能导致问题结束。请注意，脚本的大部分被指定为非Unicode字符串文字。每次
usrOutputFile之后，INSERT…EXEC的问题是EXEC是一个循环，我想将每次迭代写入一个SQL表，正如我在这里提出的问题：
