Hi,<br>
Fine - I did ask for an opinion, and I got one :-)<br>
<br>
The CSV files are from South Africa's 2011 Census - as put out by
StatsSA, and exported from SuperCROSS.<br>
In this particular file, the numeric field names are for the "Age
last birthday" of the occupant. (yep, from 0 to 120!!!)<br>
<br>
So in short, I guess there are many, many users of this data - and
for me an unnoticed error/deficiency, is still and error/deficiency.<br>
<br>
Whilst I am not too perturbed because I can get around this issue, I
figured it was my "civic" duty to raise it.<br>
<br>
Cheers for now,<br>
Zoltan<br>

<p>Hi,</p>
<p>In my opinion it is quite "special" to name columns with
integer numbers. Not what the average GIS user would do. In my
own 2-decade GIS career I never had such an issue.</p>
<p>I am not against fixing this issue, but I don't think it is a
serious issue. We have many more important issues in QGIS.</p>

Thanks for the opinion.<br>
Do I log this as a bug?<br>
<br>
Whilst I am quite happy to write a bash script to parse and
alter my 500 CSV files, I do feel that this is likely a more
serious issue, as it will affect, I assume a lot of, users
that load CSV files to join them to their spatial data.<br>
Maybe the silence on this is because it either goes unnoticed,
or there are many people just doing a work-around.<br>
<br>
Let me know.<br>
<br>
Thanks & regards,<br>

I think this could be classed as an error! The source code rejects field names that look like positive numbers (some digits optionally followed by a period and some more digits).<br>
<br>
I can't recall a reason why it should do this. It could be reasonable to require field names to be compatible to database attribute names, but I can't see any need for that within QGIS itself. This can go on a 'to-do' list to fix...<br>
<br>
Cheers<br>

Subject: [Qgis-developer] QGIS 2.10.1 Pisa - Read CSV file problem<br>
<br>
Hi,<br>
Using the above version on Win 7 64 bit, I read a CSV file (as attributes only)<br>
stipulating that "first record has field names"<br>
Record 1 is as follows:<br>
"SALnum","SALnam","1","2","3","4","5","6","7","8","9","10+"<br>
<br>
When I open the attribute table, I see that fields 1 & 2 have names SALnum<br>
and SALnam, but the rest are called 'Field_3', 'Field_4' and so on.<br>
<br>
When I edit record 1 of this CSV file to look like:<br>
"SALnum","SALnam","1p","2p","3p","4p","5p","6p","7p","8p","9p","10+p"<br>
<br>
The I get the correct field names (albeit 1p instead of just "1")<br>
<br>
Is this an error, or is there some reason further down the line, that attribute<br>
tables cannot have 'numeric' field names?<br>
<br>
Thanks and regards,<br>
Zoltan<br>
