I have an MS Access database with one table and one column holding rep(1:10)
I use:
library(RODBC)
channel <- odbcConnect("test")
sqlQuery(channel, paste("SELECT col FROM tblTest"), believeNRows=FALSE)
and get:
49
50
51
52
53
54
55
56
57
12337
What? The above should, of course, read:
1
2
3
4
5
6
7
8
9
10
I tried the 'odbcQuery' / 'sqlGetResults' dance. But no love... From a console,
'mdb-sql' and 'isql' gives correct output, so the odbc seems to be working OK.
Text columns show up fine when I select them with the above RODBC procedure.
I've fiddled with pretty much all the options that go with 'sqlQuery' with the
same output every time.
I've compacted and repaired the database. I've created other mdb's, with the
same result. When I connect to other DB's via RODBC, like MySQL, data is
correct...
What am I missing?
