SQL 2000: Change all values of a column to 0 where the value is currently NULL

I have a table entitled insurance_details_tbl that contains several float columns - I woult like to change all values in each column that are NULL to 0.

I have the below query (doing it column by column currently), which executes without error but changes nothing:

UPDATE    insurance_details_tbl
SET              value_computer = 0
WHERE     (value_computer = 'NULL')

try it with out the ' around null (this makes it a string comparison)

UPDATE    insurance_details_tbl
SET              value_computer = 0
WHERE     (value_computer = NULL)

Or for more than one column in one statement:

UPDATE table
SET column1 = isnull(column1,0), column2 = isnull(column2,0)

Beware that this UPDATE will update ALL rows indenent if there a NULL values in the columns or not. But only NULL values will change to 0, all other values are updated with theire own value.
