Hi Guys,

I need help from you..we have data like below


Table1

Col1    Col2    col3     values
200908	113	1077149	 2
200908	113	184254	 1
200908	113	989021	 2

Table2

col1    col2    Proportional_Value 
200908	113	1

Expected Output 
200908	113	1077149	 2    0.400000
200908	113	184254	 1    0.200000
200908	113	989021	 2    0.400000

The Proportional_Value will be Proportionaly distributed based on the table1 column values.

Thanks in advance

[code]
select t1.col1, t1.col2, t1.col3, t1.val, proportional_value * 1.0 * t1.val / sum(t1.val) over()
from Table1 t1
inner join Table2 t2 on t1.col1 = t2.col1
and t1.col2 = t2.col2
[/code]
