All I have are symptons right now. However, I tried on several occasions to import fairly large sets of data from an odbc source. The data that I am importing are the systables and syscolumns views on the database. The first time, it consisted of about 1.6mm rows. After the first 10,000 rows or so, it started dropping some of the data in the later columns. They started being processed as null data. I repeated this with smaller tests. I cannot find a pattern that suggest why this might be happening. At first, I thought that it might be related to crossing schemas, but that turned out not to be the case. I suppose it could be the odbc driver. However, when I do a straight query I do not see this data problem. Any ideas?
