print(yate.start_response())
connection = sqlite3.connect('users.sqlite')
cursor = connection.cursor()

form=cgi.FieldStorage(keep_blank_values=True)

bincard=form['bincard'].value
cursor.execute("SELECT * FROM (?) where BinCard=?",(table,bincard))
pt = from_db_cursor(cursor)
pt.format = True
print(pt.get_html_string())

我正在尝试从两个表中的任何一个表中检索数据，具体取决于用户在search.html中选择的内容。但如果无法弄清楚要写的查询，因为我不知道事先选择了哪个表。帮助
