Syntax Error on nested queries from google spreadsheet with blank column names

Redash 4.0.1+b4038 Pulling data from google spreadsheet the spreadsheet has some columns with blank headers If I run a query against the query results from pulling in the spreadsheet (e.g. query_45) I get an error

File "/opt/redash/redash.4.0.1.b4038/redash/query_runner/query_results.py", line 92, in create_table
    connection.execute(create_table)
OperationalError: near ")": syntax error

This is caused by create_table with a create table string that contains a blank column header at the end. e.g.

CREATE TABLE table_46 (Name, Phone, )

I hacked a fix into my query_results.py to create named columns for blank columns.

------------------query_results.py:79--------------------

def fix_column_name(name,columncounter):
    if name.strip() == '':
        name = u"BLANK{colno}".format(colno=columncounter)

    return name.replace(':', '_').replace('.', '_').replace(' ', '_')


def create_table(connection, table_name, query_results):
    columns = [column['name']
               for column in query_results['columns']]
    safe_columns = []
    colno = 0
    for column in columns:
        safe_columns.append(fix_column_name(column,colno))
        colno = colno + 1

I would suggest Excel style with letters since that’s what excel and google docs both use for the column id. It would make it easier for someone to refer back to their spreadsheet if it’s a complex one.

Let’s go with option #2 - rename the columns. But instead of blank_, maybe column_ + column number?
