Updating multiple columns in a single update transaction
I have a table with many columns. Some have a default value of 0 and need to set it to null (after removing the constraint of course).
Rather than have multiple update statements that look like this:
update table1 set column1 = null where column1 = 0
update table1 set column2 = null where column2 = 0
Is there a way to wrap these up into a single update statement or transaction with multiple where clauses?
