Dear Natalie, sorry for my misreading your query. I do not know whether increasing memory can do the trick. I am used to load smaller datasets and I find the software StatTrasfer very supportive in loading them into Stata 9.2 SE. Sorry I cannot be more helpful. Hoping the problem you are reporting can find a quick solution from other Statalisters, please accept my Kind Regards, Carlo -----Messaggio originale----- Da: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] Per conto di natalie chan Inviato: domenica 13 luglio 2008 15.42 A: statalist@hsphsun2.harvard.edu Oggetto: Re: st: R: memory problem when using odbe to read in large dataset 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?
