Get info from one table and placing it into another one

[mdmartiny]

I have two different tables and I am trying to condense them into one table.

 

The structure of the tables is

 

cc

-- ci

-- cc

-- cn

-- alpha_2

 

countries

-- id

-- cn

-- alpha_2

-- alpha_3

 

What I want to do is place the info from the column alpha_2 in the countries table into the alpha_2 column in the cc table.

I have tried inner joins, left joins, Insert and Select index. Everything that I have tried gives me an error message. I do not know what I am doing wrong and I was hoping that someone would be able to give me a hand.

 

I forgot to mention that I want the placement of the alpha_2 column to be based on the cn columns in both tables. So that the information in the alpha_2 column lines up with the right name in the cn column

try

UPDATE cc
INNER JOIN countries USING (cn)
SET cc.alpha2 = countries.alpha_2
