I have a flat source file with following settings.
Test Qualifier = "
Header row delimiter = |
I have a Column A which has value = This is the example of "value in the source file"
The error that i am seeing is the column delimiter for the column A is not found. I see the issue here is having double quotes in the column value. Any suggestions on how to fix this.
The file has to be changed. If the text qualifier of the file is a double-quote, then the actual data cannot contain double-quotes.
You can either talk to the person who creates the file and have them use a different text delimiter, or you can write a script task that edits the file and replaces the delimiting double-quotes with another delimiter, leaving the double-quotes in the data intact.
For a bit more detail, see here.

I am reading a CSV file in SAP Data Services Designer and using (") as text delimiter. The client sometimes sends data that only has one double quote in a column, without a closing " which would mark the end of string. Because of this, it ends up reading next many rows as one single column, until it encounters the next ". I need to retain the " as text delimiter as that is also required. Is there a way to avoid the anomaly where the software only sees one "?
Thanks!
Iam getting the below error when I try to load CSV From my system to Snowflake table:
Unable to copy files into table.
Numeric value '"4' is not recognized File '#EMPP/ui1591621834308/snow.csv', line 2, character 25 Row 1, column "EMPP"["SALARY":5] If you would like to continue loading when an error is encountered, use other values such as 'SKIP_FILE' or 'CONTINUE' for the ON_ERROR option. For more information on loading options, please run 'info loading_data' in a SQL client.
You appear to be loading your CSV with the file format option of FIELD_OPTIONALLY_ENCLOSED_BY='"' specified.
This option will allow reading any fields properly quoted with the " character, and even support such fields carrying the delimiter character as well as the " character if properly escaped. Some examples that could be considered valid:
CSV FORM | ACTUAL DATA
------------------------
abc | abc
"abc" | abc
"a,bc" | a,bc
"a,""bc""" | a,"bc"
In particular, notice that the final example follows the specified rule:
When a field contains this character, escape it using the same character. For example, if the value is the double quote character and a field contains the string A "B" C, escape the double quotes as follows:
A ""B"" C
If your CSV file carries quote marks within the data but is not necessarily quoting the fields (and delimiters and newlines do not appear within data fields), you can remove the FIELD_OPTIONALLY_ENCLOSED_BY option from your file format definition and just read the file at the delimited (,) fields.
If your CSV does use quoting, ensure that whatever is producing the CSV files is using a valid CSV format writer and not simple string munging, and recreate it with the quotes properly escaped. If the above data example is to be considered valid in quoted form, it must instead appear within the file as "4" or 4.
The error message is saying that you have a value in your file that contains a "4 which is being added into a table that has a number field for that value. Since that isn't a number, it fails. This appears to be happening in your very first row of your file, so you could open it up and take a look at the value. If its just one record, you can add the ON_ERROR = 'CONTINUE' to your command, so that it skips it and moves on.
Im trying to load a CSV file to redshift.
Delimiter '|'
1'st column of CSV:
1 |Bhuvi|"This is ok"|xyz#domain.com
I used this command to load.
copy tbl from 's3://datawarehouse/source.csv'
iam_role 'arn:aws:iam:::role/xxx'cas-pulse-redshift'
delimiter '|'
removequotes
ACCEPTINVCHARS ;
ERROR:
raw_field_value | This is ok" |xyz#domain.com
err_code | 1214
err_reason | Delimited value missing end quote
then I tried this too.
copy tbl from 's3://datawarehouse/source.csv'
iam_role 'arn:aws:iam:::role/xxx'
CSV QUOTE '\"'
DELIMITER '|'
ACCEPTINVCHARS ;
Disclaimer - Even though this post does not answer the question asked here, I am posting this analysis in case it helps some one.
The error "Delimited value missing end quote" can be reported in cases where a quoted text column is missing the end quote, or if the text column value has a new line in the value itself. In my case, there was a newline in the text column value.
As per RFC 4180 the specification of CSV says,
Fields containing line breaks (CRLF), double quotes, and commas
should be enclosed in double-quotes.
For example:
"aaa","b CRLF
bb","ccc" CRLF
zzz,yyy,xxx
So a valid CSV can have multi-line rows, and the correct way to import it in Redshift is to specify the CSV format option. This also assumes that all columns having the quote character in the value will have the quote character escaped by another preceding quote character. This is also as per the CSV RFC specification.
If double-quotes are used to enclose fields, then a double-quote
appearing inside a field must be escaped by preceding it with
another double quote.
For example:
"aaa","b""bb","ccc"
If the file that we are trying to import is not a valid CSV, and is just named as a .CSV file as the case may just be, then we have the following options.
Try copying the file without specifying the CSV option, and fine tuning the delimiter and escape and quoting behaviour with the corresponding copy options.
If a set of options is not able to consistently copy data, then pre-process the file to make it consistent.
In general, it helps to make the behaviour deterministic if we try to export and import data in formats that are consistent.
I’m importing a SQL view to SSIS using the Flat File Connection Manager. One of my columns in SQL has comma(s) in it. (123 Main St, Boston, MA) . When I import the data to SSIS, the commas within the column are being treated as delimiters, and my column is being broken into several columns. I have done a lot of research online, and have followed some workarounds which aren't working for me.
In SQL Server, I added double quotes around the values that have comma(s) in it.
' "'+CAST(a.Address as varchar(100))+'" '
So, 123 Main St, Boston, MA now reads “123 Main St, Boston, MA”
Then in my SSIS Flat File Connection Manager,
In the General tab:
Text Qualifier is set to “
Header Row Delimiter is set to {CR}-{LF}
In the columns tab:
Row delimiter is set to {LF}
Column delimiter is set to Comma {,}
And in the advanced Tab, all of my columns have the Text Qualified set to True.
After all of this, my column with commas in it, is still being separated into multiple columns. Am I missing a step? How can I get the SSIS package to treat my address column as one column and not break it out to several columns?
EDIT: Just to add more specifics. I am pulling from a SQL view that has double quotes around any field that has commas in it. I am then emailing that file and opening it in MS Excel. When I open it the file it read as follows:
123 Main St Boston MA" " (In three cells)
And I need it to read as
123 Main St, Boston, MA (in one cell)
Have a look of this - Commas within CSV Data
If there is a comma in a column then that column should be surrounded
by a single quote or double quote. Then if inside that column there is
a single or double quote it should have an escape charter before it,
usually a \
Example format of CSV
ID - address - name
1, "Some Address, Some Street, 10452", 'David O\'Brian'
Change every comma values with another unique delimiter which values haven't any of the characters inside,like : vertical bar ( | )
Change column delimiter to this new delimiter , and set text qualifier with double quote ( " )
You can automate the replace process using a Script Task before Dataflow Task for replacing delimiters. You can use replace script form here.
Also have a look of these resources.
Fixing comma problem in CSV file in SSIS
How to handle extra comma inside double quotes while processing a CSV file in SSIS
I ended up recreating the package, using the same parameters that are listed in my question. I also replaced this
' "'+CAST(a.Address as varchar(100))+'" '
with this in my SQL view
a.Address
And it now runs as desired. Not sure what was going on there. Thanks to everyone for their comments and suggestions.
Take this XLS file
I then save this XLS file as CSV and then open it up with a text editor. This is what I see:
Col1,Col2,Col3,Col4,Col5,Col6,Col7
1,ABC,"AB""C","D,E",F,03,"3,2"
I see that the double quote character in column C was stored as AB""C, the column value was enclosed with quotations and the double quote character in the data was replaced with 2 double quote characters to indicate that the quote is occurring within the data and not terminating the column value. I also see that the value for column G, 3,2, is enclosed in quotes so that it is clear that the comma occurs within the data rather than indicating a new column. So far, so good.
I am a little surprised that all of the column values are not enclosed by quotes but even this seems reasonable OK when I assume that EXCEL only specifies column delimieters when special characters like a commad or a dbl quote character exists in the data.
Now I try to use SQL Server to import the csv file. Note that I specify a double quote character as the Text Qualifier character.
And a command char as the Column delimiter character. However, note that SSIS imports column 3 incorrectly,eg, not translating the two consecutive double quote characters as a single occurence of a double quote character.
What do I have to do to get Excel and SSIS to get along?
Generally people avoid the issue by using column delimiter chactacters that are LESS LIKELY to occur in the data but this is not a real solution.
I find that if I modify the file from this
Col1,Col2,Col3,Col4,Col5,Col6,Col7
1,ABC,"AB""C","D,E",F,03,"3,2"
...to this:
Col1,Col2,Col3,Col4,Col5,Col6,Col7
1,ABC,"AB"C","D,E",F,03,"3,2"
i.e, removing the two consecutive quotes in column C's value, that the data is loaded properly, however, this is a little confusing to me. First of all, how does SSIS determine that the double quote between the B and the C is not terminating that column value? Is it because the following characters are not a comma column delimiter or a row delimiter (CRLF)? And why does Excel export it this way?
According to Wikipedia, here are a couple of traits of a CSV file:
Fields containing line breaks (CRLF), double quotes, and commas
should be enclosed in double-quotes. For example:
"aaa","b CRLF
bb","ccc" CRLF
zzz,yyy,xxx
If double-quotes are used to enclose fields, then a double-quote
appearing inside a field must be escaped by preceding it with
another double quote. For example:
"aaa","b""bb","ccc"
However, it looks like SSIS doesn't like it that way when importing. What can be done to get Excel to create a CSV file that could contain ANY special characters used as column delimiters, text delimiters or row delimiters in the data? There's no reason that it can't work using the approach specified in Wikipedia,. which is what I thought the old MS DTS packages used to do...
Update:
If I use Notepad change the input file to
Col1,Col2,Col3,Col4,Col5,Col6,Col7,Col8
"1","ABC","AB""C","D,E","F","03","3,2","AB""C"
Excel reads it just fine
but SSIS returns
The preview sample contains embedded text qualifiers ("). The flat file parser does not support embedding text qualifiers in data. Parsing columns that contain data with text qualifiers will fail at run time.
Conclusion:
Just like the error message says in your update...
The flat file parser does not support embedding text qualifiers in data. Parsing columns that contain data with text qualifiers will fail at run time.
Confirmed bug in Microsoft Connect. I encourage everyone reading this to click on this aforementioned link and place your vote to have them fix this stinker. This is in the top 10 of the most egregious bugs I have encountered.
Do you need to use a comma delimiter.
I used a pipe delimiter with no Text qualifier and it worked fine. Here is my output form the text file.
1|ABC|AB"C|D,E|F|03|3,2
You have 3 options in my opinion.
Read the data into a stage table.
Run any update queries you need on the columns
Now select your data from the stage table and output it to a flat file.
OR
Use pipes are you delimiters.
OR
Do all of this in a C# application and build it in code.
You could send the row to a script in SSIS and parse and build the file you want there as well.
Using text qualifiers and "character" delimited fields is problematic for sure.
Have Fun!
