[R-sig-DB] my Problem with the RODBC sql script below

[Alemu Tadesse]

Dear All,

The following script works in sql server or toad  for sql server.

SELECT MD.CallSign
  ,HD.WBAN
      ,TimeStamp_Local
      ,ref_density
      ,ref_dewpoint
      ,ref_dir
      ,ref_precip
      ,ref_press
      ,ref_rh
      ,ref_temperature_avg
      ,ref_ws_avg
      ,ref_wetbulb
  FROM ASOS.dbo.HourlyData HD
    left outer join ASOS.dbo.ASOS_MetaData MD on MD.WBAN = HD.WBAN
where CallSign = 'BOS' order by TimeStamp_Local ASC

and the result is a table of the data corresponding to those variables
listed above

But, in R it doesn't work with the following commands

ch1 <- odbcConnect(dsn="COLOMSQ", uid="DataPull", pwd="Puldata")


p3<-sqlQuery(ch1,'SELECT MD.CallSign
  ,HD.WBAN
      ,TimeStamp_Local
      ,ref_density
      ,ref_dewpoint
      ,ref_dir
      ,ref_precip
      ,ref_press
      ,ref_rh
      ,ref_temperature_avg
      ,ref_ws_avg
      ,ref_wetbulb
  FROM ASOS.dbo.HourlyData HD
    left outer join ASOS.dbo.ASOS_MetaData MD on MD.WBAN = HD.WBAN
where CallSign = BOS order by TimeStamp_Local ASC')

close(ch1)

and p3 results in

[1] "08S01 0 [Microsoft][ODBC SQL Server Driver]Communication link failure"





[2] "[RODBC] ERROR: Could not SQLExecDirect 'SELECT MD.CallSign\n
 ,HD.WBAN\n      ,TimeStamp_Local\n      ,ref_density\n
 ,ref_dewpoint\n      ,ref_dir\n      ,ref_precip\n      ,ref_press\n
 ,ref_rh\n      ,ref_temperature_avg\n      ,ref_ws_avg\n

ASOS.dbo.ASOS_MetaData MD on MD.WBAN = HD.WBAN\nwhere CallSign = BOS order
by TimeStamp_Local ASC'"

with no data

Any idea ?
 Thank you in Advance
