RE: AW: Embedded SQL formatting dates

Here is the midrange code link:

code.midrange.com/c0a1c9c4cb.html

Please note that I just typed this up to make it more generic than what my company actually used to load the table. So I apologize if there are any syntax errors.

Also, the value I chose to start the D_DATE_SK index column with is very specific.
Most DATE_DIM tables I found started with a value of 1.
I chose to start with a value of 693596. This was because the integer 693596 can be passed to the SQL DATE() function on the iSeries to generate the date '1900-01-01'.

This little change allows any of the index values to be passed directly into the DATE function to return the actual date, without needing to actually retrieve the original row from the database. I'm referring specifically to the First/Last of Month/Week columns, which all reference back to a D_DATE_SK key value.

Also, the SQL for the indexes was not included. Currently, we have created multiple indexes:

D_DATE_SK
D_DATE
D_YEAR,D_MOY,D_DOW,D_DATE
D_DATEYYMD,D_DATE
D_QOYN,D_DATE
D_MOYNA,D_DATE
D_MNYR,D_DATE
D_DATE_SK,D_DATE
D_QOYN,D_DATE
