Subj:		Distinct Count with case statement

From:		Dev a p

Hi,

I have a question. Appereciate your help. SQL needs distinct count with different column as per case statement conditions.

Table data :
Source   Col1 Col2 Col3
Plant1    x1
Plant1    x2
Plant2          x1   y1
Plant2          x1   y1
Plant2          x2   y2

SQL ????????
Select Source ,
distinct count ( Case When Source = 'Plant1' Then Col1
When Source = 'Plant2' Then (Col2 || col3) End )

Result should be :
Source Count
Plant1  2
Plant2  2

Could you please help me to put the sql code.

Thanks,
