create function [dbo].[F_TABLE_DATE]
(
@FIRST_DATE datetime,
@LAST_DATE datetime
)
/*
Function: dbo.F_TABLE_DATE
This function returns a date table containing all dates
from @FIRST_DATE through @LAST_DATE inclusive.
@FIRST_DATE must be less than or equal to @LAST_DATE.
The valid date range is 1754-01-01 through 9997-12-31.
If any input parameters are invalid, the fuction will produce
an error.
The table returned by F_TABLE_DATE contains a date and
columns with many calculated attributes of that date.
It is designed to make it convenient to get various commonly
needed date attributes without having to program and test
the same logic in many applications.
F_TABLE_DATE is primarily intended to load a permanant
date table, but it can be used directly by an application
when the date range needed falls outside the range loaded
in a permanant table.
If F_TABLE_DATE is used to load a permanant table, the create
table code can be copied from this function. For a permanent
date table, most columns should be indexed to produce the
best application performance.
