[TYPO3] optionSplit for use in where in query

[manolobimbo (Emmanuel Brost)]

hi,

i'd like to construct a sql query using the where..in clause, somathing 
like "... IN (12,25,78)".
I thought optionSplit was the way to the solution but  i don't know how 
to use it in my typoscript.
I'm still quite a newbie having difficulties with the stdWrap concept

Here is the code:
newsuids.cObject=CONTENT
      newsuids.cObject{
          table=tt_news
          select{
              pidInList=28
          }
          renderObj=TEXT
          renderObj{
              field= uid
              wrap= |*|,|*|,|*|
          }
      }

i don't think the usage of wrap is the good since i allways get wrong 
results whatever i try.

Any help would be greatly appreciated...
