Python / SQLite-如何从所有列中进行选择并求和多个列？

Question

I try to Code a search (select) function for my SQLite Database. At the Moment i get a Keyword from a TextCtrl (simplified for short example here) and i try to search in every column of my SQLite Database.

keyword = "Product_1"

Better would be if i could also select with Multiple Keywords (list):

keywords = ["Product_1", "Category_2"]

How do I search in all columns?

c.execute('SELECT * FROM Test WHERE AnyColumns=?', (keyword,))

Later on i need to Sum two of my columns. At the Moment I do it like this:

c.execute("SELECT SUM(overall_cost) FROM vm WHERE id=5")
result = cur.fetchone()[0]
c.execute("SELECT SUM(overall_price) FROM vm WHERE id=5")
result2 = cur.fetchone()[0]

Is it possible to do this in one step? Something like SUM(overall_cost) and SUM(overall_price) ?

I need those two values seperate. Not summed up to one value!

Answer 1

是的可能

"SELECT SUM(overall_cost) as overall_cost,SUM(overall_price) as overall_price  FROM vm WHERE id=5"
