Does this make sense? I otherwise don't see the error.
Using RODBC, R returns a 'Could not SQLExecDirect' error for a sqlQuery statement issued to a table containing a field ID = Order. The SQL otherwise works. I can however read the entire table to a df using sqlFetch (see below).
The target db is on SQL Server.
Example of table structure:
Taxon_Id = c(3000,3001,3002)
Group_Id = c(6,5,5)
Type = c('Fish','Fish','Fish')
Order = c('Petromyzontidae','Acipenseridae','Clupeidae')
Family = c('Petromyzontidae','Acipenseridae','Clupeidae')
txn = data.frame(Taxon_Id,Group_Id,Type,Order,Family)
Example of SQL issued to table:
txn2<-as.data.frame(sqlQuery(channel, paste('SELECT T.Taxon_Id,
T.GroupId,
T.Type,
T.Order,
T.Family
FROM Taxon T
ORDER BY 1
')) )
sqlFetch reads all table fields without error.
txn<-as.data.frame(sqlFetch(channel,"Taxon"))
Thanks for your comments.
