Converting varchar values that were derived from a constant field to Month and Year
I have a query where I am grabbing certain text out of a string. An example of the string is:
"Captured Credit Card: MasterCard, xxxx-xxxx-xxxx-xxxx, 09/19. Set as Default."
My query is pulling the expiration month and year out of that text.
SUBSTRING(ADT.MsgText, CHARINDEX('/', ADT.MsgText, 0) -2, 2) AS [Month]
,'20' + SUBSTRING(ADT.MsgText, CHARINDEX('/', ADT.MsgText, 0) + 1, 2) AS [Year]
However, I need these number values to be recognized as date values. I tried the following method, but was unsuccessful:
UPDATE CCC
SET CCC.[Month] = convert(date, convert(varchar(4), CCC.[Year]) + ' ' + convert(varchar(2), CCC.[Month]))
FROM CC_Captured CCC
The error message I get is: "Update or insert of view or function 'CCC' failed because it contains a derived or constant field."
I'm wondering how to convert these values to be date?
Any help is appreciated!
(Also I am using SQL 2016)
sql date sql-server-2016 varchar

You can use DATEFROMPARTS to construct a date in the month (first or last day of the month).
declare @MsgText nvarchar(1000) = N'Captured Credit Card: MasterCard, xxxx-xxxx-xxxx-xxxx, 09/19. Set as Default.'
select SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) -2, 2) AS [Month]
,'20' + SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) + 1, 2) AS [Year]
-- First day of the month
select DATEFROMPARTS(CAST('20' + SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) + 1, 2) as int), CAST(SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) -2, 2) as int), 1) as FirstDayOfMonth
-- Last day of the month - add 1 month to the date above and go back 1 day
select DATEADD(day, -1, DATEADD(month, 1, DATEFROMPARTS(CAST('20' + SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) + 1, 2) as int), CAST(SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) -2, 2) as int), 1))) as EndOfMonth
Or even better, use EOMONTH function:
select EOMONTH(DATEFROMPARTS(CAST('20' + SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) + 1, 2) as int), CAST(SUBSTRING(@MsgText, CHARINDEX('/', @MsgText, 0) -2, 2) as int), 1)) as EndOfMonth
