Dates..

[nipo]

Hi Gang..

 

 

I have a report that the user enters a date for '2007-03-30'... I wish to derive the date n' days before the given date

 

 

i.e. 2007-03-30 - 5days = 2007-03-25

 

 

Any ideas?

What am I missing?

 

 

Thanks in advance.

Nigel.

Nigel,

 

Try this in a TEXT FIELD:

 

Create 2 new parameters - $P{date_entered} & $P{offset}

(View > Parameters > New)

* It may be more convenient to check the Use as Prompt option for parameters where you will be entering test values.

 

Create a new Text Field.

Right click on the new text field you just created.

Click Properties

In the properties window click the Text Field tab.

Set the following:

Text Field Expression Class: java.util.Date

Evaluation Time: Now

Pattern: yyyy-MM-dd

(I think that is the default so it may not be necessary to enter this format if it's the one you prefer. In case you want a different format, just remember to use "M" for month, not "m", else you'll get the minute value instead of the month).

Text Field Expression: $P{date_entered} + $P{offset}

(I'd recommend that you use addition for flexibility)

 

The parameter $P{date_entered} is a Date parameter that you create which will allow you to enter the date.

The parameter $P{offset} is an Integer parameter that you also create which will allow you to enter the number of days to offset.

Enter a negative or positive value for $P{offset} depending on your requirements. (This is the reason why I recommend using addition in your equation above)

 

Experiment different settings and discover the best opitons for your requirements.

... I hope this helps.

Thanks,

I'll give it a lick and see what happens!

 

 

UPDATE: LOL... :whistle:

 

 

Well I'm sure I tried something like that before I asked the question... However, whatever I tried before didn't work... BUT what you outline above DOES WORK...

 

 

Many Thanks.

 

 

One other question while I'm here: How would I convert a String parameter '2007-4-6' to a Date...??

new java.util.Date('2007-4-6') doesn't work :(

how about this...

Code:

new SimpleDateFormat("MM/dd/yy"«»).parse("05/18/05"«»);
