If i understood you correctly you want to update TABLE A->Weight column which currently has null values to other value based on Id and Parameter criteria.

If this is what you want then you can use below SQL

SQL

UPDATE <table_name>
SET  WEIGHT = <SOME_VALUE>
WHERE ID = 2
AND   PARAMTER IN (1, 2, 3 , 4)
WHERE WEIGHT IS NULL

Hi,

Check this

SQL

Update tableA set Weight=10--(required Value) 
where id=2--(required Id)
and parameter=1--(required Parameter)

Hope this will help you.

Cheers
