ACCEPTED ANSWER
Score 16
pymssql claims to support the Python DB-API, so you should be able to get the .description attribute from your cursor object.
.description
This read-only attribute is a sequence of 7-item sequences. Each of these sequences contains information describing one result column: (name, type_code, display_size, internal_size, precision, scale, null_ok)
So, the first item in each of the "inner" sequences is the name for each column.
ANSWER 2
Score 7
You can create a list of ordered column names using list comprehension on the cursor description attribute:
column_names = [item[0] for item in cursor.description]
ANSWER 3
Score 4
To get the column names on a single comma separated line.
colNames = ""
for i in range(len(cursor.description)):
desc = cursor.description[i]
if i == 0:
colNames = str(desc[0])
else:
colNames += ',' + str(desc[0])
print colNames
Alternatively, pass the column names to a list and use .join to get them as string.
colNameList = []
for i in range(len(cursor.description)):
desc = cursor.description[i]
colNameList.append(desc[0])
colNames = ','.join(colNameList)
print colNames

It's a basic solution and need optimizing but the below example returns both column header and column value in a list.
import pymssql
def return_mssql_dict(sql):
try:
con = pymssql.connect(server, user, password, database_name)
cur = con.cursor()
cur.execute(sql)
def return_dict_pair(row_item):
return_dict = {}
for column_name, row in zip(cur.description, row_item):
return_dict[column_name[0]] = row
return return_dict
return_list = []
for row in cur:
row_item = return_dict_pair(row)
return_list.append(row_item)
con.close()
return return_list
except Exception, e:
print '%s' % (e)
