I have an Excel file that contains 47394 rows plus one row at the top containing the column headings. If I hit Ctrl-End in Excel, cell F47395 is activated, which is what I expect. I am using this Excel file as the data source in a SSIS package data flow task. The data flows into a SQL table via a Data Conversion transform and an OLE DB destination. All 47394 rows are flowing into the SQL table correctly but what's baffling me is an additional 128 rows entering the SQL table, each of which is full of NULLs.
Can anyone explain why this is happening and more importantly how to prevent it happening within my SSIS package? I suppose I could add an Execute SQL task that deletes all rows with a NULL column, which could follow my data flow. However, this seems a less than elegant way of doing it and I was wondering if it can be managed within the data flow task.
Many thanks in advance.
