Some useful Date expressions for SSIS

I engaged in creating some date expressions yesterday, these expressions are very common needed. So I bring them here to share.

Suppose your Date Field name is FillDt ,

1- number of days in the quarter of date field.

For example
                     If the fillDt is "2002-03-04" the count will be 63
                     If the fillDt is "2002-06-20" the count will be 81

expression:

DATEDIFF("DAY",(DT_DATE)(((DT_WSTR,4)YEAR(fillDt)) + "-" + ((DT_WSTR,2)(((DATEPART("QUARTER",fillDt) – 1) * 3) + 1)) + "-1"),fillDt)

2-

number of days in the year of date field.

For example
                     If the fillDt is "2002-03-04" the count will be 63
                     If the fillDt is "2002-06-20" the count will be 171

expressio
n:
DATEDIFF
("DAY",(DT_DATE)(((DT_WSTR,4)YEAR(fillDt)) + "-1-1"),fillDt)

3- Number of months of the quarter of date

For example:
                    If the fillDt is "2002-03-31" the count will be 3
                    If the fillDt is "2002-06-30" the count will be 3
                    If the fillDt is "2002-07-13" the count will be 1

ex
pression:
D
ATEDIFF("MONTH",(DT_DATE)(((DT_WSTR,4)YEAR(fillDt)) + "-" + ((DT_WSTR,2)(((DATEPART("QUARTER",fillDt) – 1) * 3) + 1)) + "-1"),fillDt)

4- quarter number of date

For example
                    If the fillDt is "2002-03-04" the quarter count will be 1
                    If the fillDt is "2002-06-20" the quarter count will be 2
                    If the fillDt is "2002-10-06" the quarter count will be 4

expressio
n:
(DT_WSTR
,1)(DATEPART("QUARTER",fillDt))


5- quarter start date

For example
                   If the fillDt is "2002-03-04" the "quarterStartDt" will be "2002-01-01"
                   If the fillDt is "2002-06-20" the "quarterStartDt" will be "2002-04-01"

exp
ression:
(D
T_DATE)(((DT_WSTR,4)YEAR(fillDt)) + "-" + ((DT_WSTR,2)(((DATEPART("QUARTER",fillDt) – 1) * 3) + 1)) + "-1")

6- quarter end date
For example
                   If the fillDt is "2002-03-04" the "quarterStopDt" will be "2002-03-31"
                   If the fillDt is "2002-06-20" the "quarterStopDt" will be "2002-06-30"

expression:
DATEA
DD("DAY",-1,DATEADD("MONTH",3,(DT_DATE)(((DT_WSTR,4)YEAR(fillDt)) + "-" + ((DT_WSTR,2)(((DATEPART("QUARTER",fillDt) – 1) * 3) + 1)) + "-1")))
