15/12/2003 12:15:06 217,1 2758 8,3 35,1 79,6 86,4
15/12/2003 12:15:07 217,1 2768 8,3 35,1 79,6 86,4
My code (i use the R 1.7.1 for windows xp) is the following:
library(RODBC)
> canal<-odbcConnectExcel("c:/prueba4.xls")
> tablas<-sqlTables(canal)
> tablas
TABLE_CAT TABLE_SCHEM TABLE_NAME TABLE_TYPE REMARKS
1 c:\\prueba4 <NA> Hoja1$ SYSTEM TABLE <NA>
2 c:\\prueba4 <NA> Hoja2$ SYSTEM TABLE <NA>
3 c:\\prueba4 <NA> Hoja3$ SYSTEM TABLE <NA>
> tbl<-sqlFetch(canal,substr(tablas[1,3],1,nchar(tablas[1,3])-1))
> tbl[1]

�Which is the mistake?.
And the second question is the command odbcFechRows() don't work,
for example if write
tbl<-odbcFetchRows(canal) in place of sqlFetch result a error
stat = -1 and the list is NULL
odbcGetErrMsg return No results available. Thank Ruben
