local xlsfile  "dho_daily_30000_2011-07-30(1).xls"
Hi Ricardo,

You have create the ODBC connection first before you can call data
from it. Either you create them manually or create them on the fly:

// declare name of the Excel file to read from
local xlsfile "dho_daily_30000_2011-07-30(1).xls"

// list the worksheets of interest
local sheets ""Sheet1" "Sheet2" "Sheet3" "Sheet4""

// Extract data from Excel to Stata
local sheetno: list sizeof sheets
forvalues i=1/`sheetno' {
   local k: word `i' of `sheets'
   local my_sheet "`k'"
   local source "Excel Files;DBQ=`xlsfile'"

   clear
   odbc load, dsn("`source'") table("`my_sheet'$")


Regards,
Subrata
