Multipart queries in SQL Server with RODBC - sql-server

Question

I am trying to use GO to get R to pull a multipart query from a SQL Server database but R keeps erroring out on me when I try this. Does anyone know a workaround to get RODBC to run multipart queries?
Example query:
query2 = "IF OBJECT_ID('tempdb..#ATTTempTable') IS NOT NULL
DROP TABLE #ATTTempTable
GO
SELECT
* INTO #ATTTempTable
FROM ETL.ATT.fact_responses fr
WHERE fr.ResponseDateTime > '2015-07-06'
"
channel <- odbcConnect("<host name>", uid="<uid>", pwd="<pwd>")
raw = sqlQuery(channel, query2)
close(channel)
and result
> raw
[1] "42000 102 [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Incorrect syntax near 'GO'."
[2] "[RODBC] ERROR: Could not SQLExecDirect 'IF OBJECT_ID('tempdb..#ATTTempTable') IS NOT NULL\n DROP TABLE #ATTTempTable\n\nGO\n\nSELECT\n\t* INTO #ATTTempTable\nFROM ETL.ATT.fact_responses fr\nWHERE fr.ResponseDateTime > '2015-07-06'\n'"

Answer 1

Because your query contains multiple line with conditional logic it resembles a stored procedure.
Simply save that stored procedure in SQL Server:
CREATE PROCEDURE sqlServerSp #ResponseDateTime nvarchar(10)
AS
IF OBJECT_ID('tempdb..#ATTTempTable') IS NOT NULL
DROP TABLE #ATTTempTable;
GO
-- suppresses affected rows message so RODBC returns a dataset
SET NO COUNT ON;
GO
-- runs make-table action query
SELECT * INTO #ATTTempTable
FROM ETL.ATT.fact_responses fr
WHERE fr.ResponseDateTime > #ResponseDateTime;
GO
And then run the stored procedure in R. You can even pass parameters like the date:
channel <- odbcConnect("<host name>", uid="<uid>", pwd="<pwd>")
raw = sqlQuery(channel, "EXEC sqlServerSp #ResponseDateTime='2015-07-06'")
close(channel)

You can't. See https://msdn.microsoft.com/en-us/library/ms188037.aspx
you have to divide your query into two statements and run them separately.
