Question

I want to get the column names of a table, but there a over million data in it. So I cannot use:

cursor.execute(\"SELECT * FROM table_name\")
print cursor.de         


        

Answer 1

The correct way to do this would be to use "SHOW columns FROM table_name" however, you could also simply add a LIMIT to your existing query:

cursor.execute("SELECT * FROM table_name LIMIT 0")
print cursor.description
