Hi there, recently I tried to read in several series via odbc *including one dummy* series and I forgot to change its entries from "No" and "YES" to "0" and "1". However, SQL retrieved for all series the correct number of observations.*BUT ALL SERIES* were corrupted. That's why two thoughts come up: 1) I know from importing STATA files that GRETL changes string entries to number entries. Does GRETL use information provided by the STATA file, or does it this job by itself? If yes, would it be possible to add this functionality to the odbc read in process? 2) If one has always to provide numerical entries and e.g. one series is not correcltly specified then actually only this series should be corrupted.
