| + | UPDATE | ||
| + | table | ||
| + | SET | ||
| + | field = '' | ||
| + | WHERE | ||
| + | ISNULL(field, 'dummyvalue') = 'dummyvalue' | ||
| + | </code> | ||
| + | |||
| + | ISNULL checks if "field" is null and if it is null it returns 'dummyvalue', if that's equal to 'dummyvalue' then it sets the field to '' (which is NOT the same as null in SQL Server). | ||
