Date Conversion

  
if i want to convert a numerical month into a string ex: 01 into Jan (without using ADV queries), is there a way to do it?

Thx
yes, with an action.

simple switch statement should be the "easiest" way

Create a static entity with ID values (change data type to text if needed) of 01-12 and Label values of January through December.  Then, in your simple query, just have a join between the month number and the static table ID and add the Label field to the list of result fields.  Easy!!

Hope this helps,
Curt
thank you althought i was trying to avoid doing that too :P but thx anyway
Ok, so you want a solution but you are not willing to do the two minutes of work it will take?  I guess we need a platform that reads minds. 

<< Sorry for the sarcasm.  I was not going to say anything but you asked for help, you received two easy solutions within one hour and you're not willing to implement either of them?  I don't understand. >>
Norman, You can also have a look at 
http://msdn.microsoft.com/en-us/library/system.globalization.datetimeformatinfo.getmonthname(v=vs.90).aspx

You can create an extension to use it in outsystems. 

 

oh its not that Curt, sorry for the mistunderstand, i was avoinding the use of adv query for it requires the use of database, and i cant use database since, im still bootstraping them :(, so the database still doesnt exist
None of the suggestions use an advanced query.  If you are trying to convert the numeric values to the names of the months as part of the bootstrap process that's easy enough to do using what Stalter provided, but doing so is not a good database design decision.  To help more we'd have to try and understand what you are ultimately trying to do.
well what i was exactly trying to do that, receiving a resource "an excel sheet" that has a date time column, but when i bootstrap it, i want to convert it in to a string and get the month of that date time column in to an entity atribute, just that.

but since using switch seems bad implemantation... gonna see if in the assignment widget i can find any function that helps...

Since someone mentioned advanced queries, I thought I'd add this option as well.  You can use an advanced query without a database table existing.

1 Create a structure (e.g. Month) in you espace with a single text attribute (e.g.Name)
2 Create an advanced query (e.g. GetMonthName) in you action that has an integer @month input parameter and uses the newly created Month structure as the output.
3 Use the folowing for the query:

SELECT
  CASE 
    WHEN @month = 1 THEN 'Jan'
    WHEN @month = 2 THEN 'Feb'
    WHEN @month = 3 THEN 'Mar'
    WHEN @month = 4 THEN 'Apr'
    WHEN @month = 5 THEN 'May'
    WHEN @month = 6 THEN 'Jun'
    WHEN @month = 7 THEN 'Jul'
    WHEN @month = 8 THEN 'Aug'
    WHEN @month = 9 THEN 'Sep'
    WHEN @month = 10 THEN 'Oct'
    WHEN @month = 11 THEN 'Nov'
    WHEN @month = 12 THEN 'Dec'
    ELSE ''
  END

In the action flow after the advanced query is executed, you can use GetMonthName.Month.Name.Value to get the correct text value.

If you place all of this in a logic action with the appropriate input and output parameters, you have a nice reusable function.

 
Hi,

The best sugestion is Statler's one, followed by kota's as second choice.
I would stay away from database if something can be done in actions...since usually database is always the performance bottleneck on applications.

Agreed.  My suggestion was simply to illustrate that it could be done without a table present.
ok thank you all for the sugestions
