Question
Help Importing a CSV file without using SSIS
I'm having a lot of problems trying to import a CSV file. There are a different number of columns for different rows. Also some of the rows include comments typed in by users in an input field and they typed in line breaks so this is causing problems. There are no problems importing this into Access using doCmd.transfertext but I need to be able to do all of this from Coldfusion. An example of the CSV file is below.
Example of CSV file.
1,"abc1","abc2","abc3","ab
1,"abc1a","abc2a","abc3a",
1,"abc1b","abc2b","abc3b",
2,"abc1","abc2","abc3","ab
2,"abc1a","abc2a","abc3a",
2,"abc1b","abc2b","abc3b",
3,"abc1","abc2","abc3","ab
3,"abc1a","abc2a","abc3a",
3,"abc1b","abc2b","abc3b",
4,"abc1","This is a comment with a line break in it.","abc3","abc4","abc5",
4,"abc1a","This is another comment with several line breaks in it.","abc3a","abc4a","abc5
4,"abc1b","abc2b","abc3b",
I could really use some help on importing this file into my SQL Server 2005 Database.
Thanks,
Tim

Neither of those solutions worked. The biggest problem is the line breaks typed in by the users. Once any solution that I've seen hits those it forces a new row to be created where there shouldn't be one. Also I don't have access to create any new data sources so the solution in the first link wouldn't work for me. Any other suggestions?
before you rund any normal solution you need to remove line breaks within quotes like this:
<cfset withinquotes = 0>
<cfloop from="1" to="#len(csv)#" index="i">
<cfif mid(csv,i,1) eq """">
<cfif withinquotes>
<cfset withinquotes = 0>
<cfelse>
<cfset withinquotes = 1>
</cfif>
<cfelseif (mid(csv,i,1) eq chr(13) or mid(csv,i,1) eq chr(10)) and withinquotes>
<cfset csv = RemoveChars(csv, i, 1)>
<cfset csv = insert(" ",csv,1)>
</cfif>
</cfloop>
now your CSV variable will have all the line breaks within the quotes replaced with spaces so you can use the normal methods of converting the lines into an array.
I would suggest you change all the commas that are delimiters to pipes "|" and then use that as your delimiter when parsing out the fields instead of commas. Pipe delimiting is often the better to use than comma delimiting for this very reason.
<cfset withinquotes = 0>
<cfloop from="1" to="#len(csv)#" index="i">
<cfif mid(csv,i,1) eq """">
<cfif withinquotes>
<cfset withinquotes = 0>
<cfelse>
<cfset withinquotes = 1>
</cfif>
<cfelseif (mid(csv,i,1) eq chr(13) or mid(csv,i,1) eq chr(10)) and withinquotes>
<cfset csv = RemoveChars(csv, i, 1)>
<cfset csv = insert(" ",csv,1)>
<cfelseif mid(csv,i,1) eq "," and not withinquotes>
<cfset csv = RemoveChars(csv, i, 1)>
<cfset csv = insert("|",csv,1)>
</cfif>
</cfloop>
Sorry I haven't gotten back faster. I had some other issues come up that had to be taken care of. I have messed around with this for a while now and I don't think this solution will work either now. It's just taking way to long to process the files. Anywhere from 15-30 minutes a file. Any other suggestion on ways I can import this file?
