I have a table with VARCHAR field that has a value like A "B" C. When I click "Download Results" in the Web UI and inspect the resulting CSV or TSV file, the value returned is A ""B"" C, meaning the sets of quotes have been duplicated. Note that I do not see this issue with a COPY INTO statement (exported to S3).

To replicate this issue easily, you can run the following in a Snowflake Web Console session and download the results to CSV:

    SELECT 'A "B" C' AS QUOTE_FIELD ;

Note that double quotes are simply duplicated, so an example of two double quotes (A ""B"" C) would export as A """"B"""" C.

Does anyone know of a way to resolve this unexpected behavior?

hey TSV export looks good, but not csv.

  • Hi Suzy - thanks, I have a Snowflake support ticket open.
  • No, it is a bug. Either the field should be exported as "A ""B"" C", or A "B" C, which is imported correctly in Excel, but A ""B"" C does not import as the original result set.
