在R，Microsoft SQL Server中执行SQL函数

Question

I have a number of functions written on our Microsoft SQL servers.

I can easily access and query all data normally, but I cannot execute functions on the server using RODBC .

How can I execute sql-functions using R? Are there other packages that can do this?

Or do I need to switch strategies completely?

Example:

require(RODBC)
db <- odbcConnect("db")

df <- sqlQuery(channel = db, query = "USE [Prognosis] 
GO 
SELECT * FROM [dbo].[Functionname] ("information_variable")
GO" ) 

Error message:
"42000 102 [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'GO'."                                                                                                               
[2] "[RODBC] ERROR: Could not SQLExecDirect 'USE... "

Answer 1

This turned out to work:

df <- sqlQuery(channel = db, 
query = "SELECT * FROM [dbo].[Functionname] ("information_variable")" )

So I dropped USE [The_SQL_TABLE] and GO
