I have a table where I am attempting to take 3 database table values and reformat them in a single value. Here is the SQL statement that I have at the moment:
SELECT
CASE WHEN cb_cardtype = 'Discover Credit Card'
THEN 'DS'
END +
';' + RIGHT(cardnumbers,4) + ';' + LPAD(MONTH(planexpdate), 2, '0') +
'/' + LPAD(YEAR(planexpdate), 2, '0') AS account_billing_key
FROM my_table
So what I wanted to get as an output here would be:
DS;4242;07/14
The problem is that I am using the + to attempt this, which actually adds the values together. Rather, I understand that I need to use CONCAT() to merge the values. I am unclear about how I can pull the individual values and then concatenate them as desired.
If your query is otherwise correct, all you need to do is to wrap all the strings you want to concatenate - comma separated - inside a call to CONCAT;
SELECT
CONCAT(
CASE WHEN cb_cardtype = 'Discover Credit Card' THEN 'DS' END,
';',
RIGHT(cardnumbers,4),
';',
LPAD(MONTH(planexpdate), 2, '0'),
'/',
LPAD(YEAR(planexpdate), 2, '0')
) AS account_billing_key
FROM my_table
