I'm trying to display a DATE field fetched from a DB2 instance.
In Oracle I'd use something like:
to_char(v_date, 'YYYY-MM-DD')
What's the equivalent in AS400 DB2?
In V5R3 or later, use the CHAR() function. To get the same results as your Oracle example, use this:
char(v_date, ISO)
When using the CHAR() function with date fields, you can choose from the following formats: ISO, USA, EUR, JIS, and local. When using "local" as the format, it will use the attributes of the ODBC connection job, which will probably be the system-level values of date format and date separator. The other date formats are as such:
ISO = 'yyyy-mm-dd' USA = 'mm/dd/yyyy' EUR = 'dd.mm.yyyy' JIS = 'yyyy-mm-dd'
In V5R4, you can use the varchar_format function. The only valid formats for this function are 'YYYY-MM-DD HH24:MI:SS' and 'YYYY-MM-DD'.
In V6R1 you have better formatting options for the varchar_format function. As mentioned in another answer, to_char is an alternative to varchar_format.
