Ya, thanks  pdd1lan.

I used the following query.

If exists(select * from Translations where TNR_LANGUAGE = @TNR_LANGUAGE AND C_LABELNAME = @C_LABELNAME)
Begin
      update Translations set C_TRANSLATEDSTRINGS = @C_TRANSLATEDSTRINGS where TNR_LANGUAGE = @TNR_LANGUAGE AND C_LABELNAME = @C_LABELNAME
End

Else
Begin

insert into Translations (TNR_LANGUAGE,C_LABELNAME,C_TRANSLATEDSTRINGS)values (@TNR_LANGUAGE,@C_LABELNAME,@C_TRANSLATEDSTRINGS)

End
pdd1lan

does your query work?

here are some suggestion:

-not hurt to have try... catch to capture any error might occur around your if statement.  

-the way you do is fine, but might consider not to use "select *"  when you just check for exist record, I suggest using "Select 1" instead.

If exists(select 1 from Translations where TNR_LANGUAGE = @TNR_LANGUAGE AND C_LABELNAME = @C_LABELNAME)

here is an article, might have better explanation why:
