I have a very simple Z SQL method that works fine when I test run it. But when I call it from a Python script (see below) and attempt to print the result, I get the following error:
Error Type: TypeError
Error Value: cannot concatenate 'str' and 'ImplicitAcquirerWrapper' objects
------ Python script -----
# Import a standard function, and get the HTML request and response objects.
##from Products.PythonScripts.standard import html_quote
request = container.REQUEST
RESPONSE = request.RESPONSE
data = context.getChunk1() for data_row in data: print "data-row="+data_row return printed
You need to iterate over the columns in the row:
data = context.getChunk1() for data_row in data: print "data-row=" for item in data_row: print item + ' ' return printed
It is more normal to fetch one result row at a time:
for data_row in context.getChunk1(): # and handle the results by column name print data_row.FirstName print ' ' print data_row.Surname ... return printed

Thanks Cliff. What you propose works fine! -- christer
