Issue:
I am trying to parse a csv file from an external provider into a MySQL database using Azure Data Factory. Some of the rows parse fine, but Azure Data Factory is unable to correctly parse a row that has "" followed at any point by a comma like "This is 25"" wide, and 500' long"
For example, this snippet:
0.00,"EZ Load Gray End Cap Laminating Roll Film, Gloss, 25"" x 500', 1.5 mil, 2 Rolls",CHN
Should be parsed into:
- 0.00
- EZ Load Gray End Cap Laminating Roll Film, Gloss, 25" x 500', 1.5 mil, 2 Rolls
- CHN
But that's not what's happening. It's getting parsed into:
- 0.00
- EZ Load Gray End Cap Laminating Roll Film, Gloss, 25" x 500',
- 1.5 mil
- 2 Rolls
- CHN
I assume it has something to do with the "" and then it sees the next , as a field delimiter even though it's actually inside the larger quoted string. It's able to parse other chunks like:
0.00,"A, b, and c","column 3"
The problem only seems to happen when the double-double and comma(s) are inside a larger string.
How can I resolve this issue?
I have the Quote character set to "Double quote," and the delimiter set to comma, but there doesn't seem to be anywhere to tell Azure Data Factory how to handle "escaped quotes" like ""
Solution:
I am using the Copy Data action. I had looked at that article, but somehow missed that it was setting the ESACAPE character. I thought it was setting the QUOTE character - which I already had at double quotes.
Setting the ESCAPE character seems to have solved my issue.
If I missed anything please let me know and I'd be happy to add it to my answer, or feel free to comment below with any additional information.
