Error when uploading integersHi,
I ran into the following problem: I used the COPY command to upload a large number of records and I got an error saying that a particular field was expecting an int. In the file which I am trying to upload fields are separated with commas ",", and records are separated with new-line characters - "\n". The value it was trying to upload and failed was basically an empty field - ",,". I worked around the problem by setting every entry in the column that was not set to zero - so the field would get its int, and later changing it back to null in the table. But it seems like a common task to upload null values into an integer column, so why would it fail? ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Empty fields are converted to NULL values, unless the NULL value representation is explicitly overruled in the COPY command. In case of doubt where to look for the error, extract the violated line and copy it into your table to assure that it is not a side-effect of e.g. an error in earlier fields, such as a field separator as part of a string field. See the documentation for further details. regards, Martin > > > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------------ > Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day > trial.
