SQL does not care about date formats. A date is only a numeric value and
date formats are only used to make this scaliger no readable.
If you debug your code and fetch any date value into a date field. The
format of the date that is displayed depends on the date format of the RPG
variable.
If you want to convert or display the date into any other format, it has to
be converted into a character version, by using one of the scalar functions
CHAR() or VARCHAR_FORMAT().
Example:
Exec SQL Values(Char(Current_Date, USA),
VarChar_Format(Current_Date, 'MM/DD/YY'),
VarChar_Format(Current_Date, 'MMDDYYYY'))
into :HostDateMMDDYYYY, :HostDateMMDDYY;
If you need to convert a date into a numeric representation in the format
YYYYMMDD, this can be done since release 7.2 with one of the scalar
functions DEC(), Integer() or BigInt():
Example:
Exec SQL Values(Dec(Current_Date, 8, 0),
Int(Current_Date),
BigInt(Current_Date))
Into :HostDateDec, :HostDateInt, :HostDateBigInt;

Betreff: Embedded SQL formatting dates
Birgitta tantalized me a bit ago. SQL does so much so well.
So far I have not found a way to set the output format for a date. This
does not work:
exec sql select date(:WRKDAT)
into :MDYYDATE "mm-dd-yyyy" from SYSIBM/SYSDUMMY1;
(As an aside, it seems to need SYSIBM/SYSDUMMY1. At least I am #1, eh?
Or does that mean something else?)
