RODBC: sqlQuery is successful, but a similar sqlFetch returns error
Greetings guRus --
I have successfully queried a large (24,445 rows by 281 cols.) in-house
database using the following RODBC query (without the line breaks)
testout <- sqlQuery(channel, "select idSchedule,EXCL_Total from
dbo.vwC1198_2006_RawData_With_CMPL_EXCL")
This returns a dataframe of 24445 rows and two columns (as intended),
but the following command
testout <-
sqlFetch(channel,"dbo.vwC1198_2006_RawData_With_CMPL_EXCL",colnames =

Package for converting R datasets into SQL Server (create table and insert statements)?

DISTINCT?
This should be easy, but I''m stumped...

belongs_to :y
end
class Y < ActiveRecord::Base
has_many :x
end
The y table has a column names. The x table has a column value. I
want the list of values in x for the name "Location" in y. Yes, there
are many repetitions.
I can probably hack together an SQL statement to do this without too

Execute SQL Stored Procedure in R
Dear all,
I would like R to retrieve a table resulting from execute sql stored procedures. What function can I use? Can RODBC do it.
I tried
channel1 <- odbcConnect("ptsecmstqa01-alpha")
query <- paste("execute DB.dbo.usp_test")
Data<- sqlQuery(channel1, query)
However, it returned blank.

HABTM and has_many through only work in one direction

When I create a recipe object, it works fine and I can see all the
feeds that it''s a part of but when I create a feed object and try to
access all its recipes I get an error saying:
OLE error code:80040E37 in Microsoft OLE DB Provider for SQL Server
Invalid object name ''dbo.msn_lifestyles_feeds_recipes''
I''ve also tried this using has_many :through and I get the same error.
Any help on this would be greatly appreciated.

join update seperation?
I have a legacy DB without access to change the user or group table

usergroup join so I thought the joins would be pretty much like my other

shows habtm checkboxes for the join and the updates are occuring for the
join but I''m
