_MAKE_TIMESTAMP() not working with substrings casted to int

[psrpsrpsr]

Hi all, I'm creating a report where a user will search for customer records using a date of birth.

Rather than use the Date Prompt and force them to click 3 dozen times to get to the desired DOB, I want them to be able to enter a birth date into a Text Box Prompt in a uniform format: DD/MM/YYYY.

The parameter name is p_dob.

So if the input into the Text Box Prompt is 04/09/1965, the output would be:
YEAR:    SUBSTRING(?p_dob?,7,4) = 1965
MONTH: SUBSTRING(?p_dob?,1,2) = 04
DAY:      SUBSTRING(?p_dob?,4,2) = 09

I am able to successfully do the following:
1.) Cast these functions to ints, and concatenate them as a proof of concept, like this:
CAST(substring(?p_dob?,7,4) , integer) || CAST(substring(?p_dob?,4,2) , integer) || CAST(substring(?p_dob?,1,2) , integer) = 196549

2.) Create a datetime with _MAKE_TIMESTAMP() by passing in integers as a proof of concept.

What is NOT WORKING is using the _MAKE_TIMESTAMP function with these casted INT values, like this:
_MAKE_TIMESTAMP( CAST(substring(?p_dob?,7,4) , integer) , CAST(substring(?p_dob?,4,2) , integer) , CAST(substring(?p_dob?,1,2) , integer)
OR
_MAKE_TIMESTAMP( [YEAR] , [MONTH] , [DAY] )

If these substrings are successfully being casted as INTs, why aren't they being accepted as the integer arguments in the _MAKE_TIMESTAMP() function?
I have tried using a reference query to pull in the casted integer date fields, but no luck.

The error message is:
XQE-GEN-0002  An unexpected exception occurred. CAF-WRN-2082 An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2017-10-05-11:13:22.302-#1333

Did you try googling the error code:

Yes, it does not seem to be applicable here. I am running the report output to HTML, not Excel.

Hi,
Try the expressions in the attached xml and see if it helps.

Good luck

Hi NewGuy, in the interest of readability and understanding your suggestion, allow me to summarize - you're suggesting to do the following:

Data Item1 = substring(?dob?,1,4) + '-' + substring(?dob?,5,2) + '-' + substring(?dob?,7,2) + ' ' + '00:00:00.000'

Data Item2 = cast([Data Item1],timestamp)

So instead of using _MAKE_TIMESTAMP(), you're suggesting creating a string for which you can do: CAST(formatted timestamp string, timestamp).

I will try this and report back.

Hi,

Yes, because the below expression will result in 1978.

CAST(substring(?p_dob?,7,4) , integer) || CAST(substring(?p_dob?,4,2) , integer) || CAST(substring(?p_dob?,1,2) , integer) = 196549

Alternatively you can create 3 dataitems for each substring and  you can use _make_timestamp([D1],[D2],[D3])

Good luck

Hi New_guy, can you clarify what you mean by: "Yes, because the below expression will result in 1978.

CAST(substring(?p_dob?,7,4) , integer) || CAST(substring(?p_dob?,4,2) , integer) || CAST(substring(?p_dob?,1,2) , integer) = 196549"

Also, I tried this, both in my query where the fields are casted as Data Items, and in a reference query. No Luck.

Alternatively you can create 3 dataitems for each substring and  you can use _make_timestamp([D1],[D2],[D3])

Hi,

Pls try the with the below approach -

[DOB(char)]
1) cast DoB to varchar - cast([DOB],varchar(10)) 

[ConcatDOB]
2) After converting  DoB to varchar extract day, month & year using substring and concatenate as below
substring([DOB(char)],9,2)||substring([DOB(char)],6,2)||substring([DOB(char)],1,4)

3)Replace all instances of '/' in ?p_dob?
[paramDoB] as replace(?p_dob?,'/','')

5) Add filter to the report
[ConcatDOB]=[paramDoB]

Hope that makes sense


Life gets easy with sql server, just add the filter below -

convert(varchar(10),[Date of Birth],103)=?p_dob?

Raj
