I have also tried to read in the dataset separately using "in": odbc load in 1/60000, table ("firms") odbc load in 60001/120000, table ("firms") .. The first command works, I successfully read in the first 60000 observations but the second and other commands did not work, that is, the Stata only read in the row of the variable names but no observation was read in. Have anyone met similar problem before?
