"xxx" is not a known field (line 301, visparser.php)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Having a csv file like this:
"date_time as datetime","Value as number","valueID as number","user"
2005-01-06 10:26:00,-0.7,1,Alias1
2005-01-06 10:35:00,-0.98,1,Alias2

2. And using
   var query = new
google.visualization.Query('http://www.example.com/csvtable.php');

with the query: 
  query.setQuery('select Value,user where valueID=1'); 

What is the expected output? What do you see instead?
The data table with the query. The message error " 'valueID' is not a known
field" is obtained instead.

Please provide any additional information below.
