I receive data in a certain format. Dates are numeric(8,0). For example 20120101 = YYYYMMDD
There exists rows with values like (0,1,2,3,6)
in that date field, thus not a date.
I want to check if it is a date and convert it, else it can be null.
Now the following code works, but I was hoping there is a better way.
(CASE WHEN [invoice_date] LIKE '________' --There are 8 underscores
THEN convert(datetime, cast([invoice_date] as char(8)))
END) AS Invoice_Date
Any help will be appreciated.
use isdate function like ..
(CASE WHEN ISDATE (invoice_date) = 1
THEN convert(datetime, cast([invoice_date] as char(8)))
END) AS Invoice_Date
