I'm tryuing to get the RODBC package to work with a MS Sql database
(Wonderware's InSQL). I'm able to connect to the database using the
following:
version
_
platform i386-pc-mingw32
arch x86
os Win32
system x86, Win32
status Under development (unstable)
major 1
minor 4.0
year 2001
month 10
day 29
language R > library(RODBC)
library(RODBC)
> channel <-
odbcConnect("SCADA2","ways1","LO&B*O",case="msaccess")
> channel
channel
[1] 0
And an abreviated table list is:
...
25 Runtime dbo AnalogHistory
TABLE
...
When I try to query the table, I get:
> test <- sqlQuery(channel,"select datetime, value from analoghistory
where
tagname = 'a055-re-0020_ph_pv_flt' and datetime >= 'nov 1, 2001
2:00pm'")
> test
test
[1] "37000 201 [Microsoft][ODBC SQL Server Driver][SQL Server]Procedure
'sp_prepare' expects parameter '@stmt', which was not
supplied."
[2] "[RODBC]ERROR: Could not SQLPrepare"
Any thoughts?
