I tried your suggestion...
library(RODBC)
channel = odbcConnectAccess("db.mdb")
sqlCopy(channel,"Select * from tab","newtab",destchannel=channel,
safer=TRUE,append=TRUE,rownames=FALSE,fast=FALSE)
odbcClose(channel)
however, I am still running into errors, both when appending to an existing
table, or creating a table if the destination table does not exist.
The code I am using is:
query <- " select * from tblHistorical where MyDate between '2008-11-21'
and '2008-11-25' ; "
sqlCopy(RemoteChannel, query, "NewTable", destchannel=LocalChannel,
safer=TRUE, append=TRUE, rownames=FALSE, fast=FALSE)
If I run this when "NewTable" does not yet exist in the database, it returns
the error:
ERROR: Could not SQLExecDirect 42000 102 [Microsoft][ODBC SQL Server
Driver][SQL Server]Incorrect syntax near '16'.
And when this runs when "NewTable" is already defined with correct data
types, I get the error:
Error in sqlSave(destchannel, dataset, destination, verbose = verbose, :
unable to append to table ‘NewTable’
It seems I can't get it to work in either scenario.
Any insight anyone could provide would be greatly appreciated.
