I have a table which has different types of balance and I need to deduct the balance from different columns based on availability.
Here is the query (Sample) I tried to use but it didn't work
update table_A
set case
when column_A>table_B.balance then column_A
when column_B>table_B.balance then column_B
when column_C>table_B.balance then column_C
end =value
from table_B
on table_A.Id=table_B.id
Thanks!
