Hi There are many records in a field of table. I want to set contains of field to null only for some records.
For example :

Update mytable
Set myfields = null
Where myfields = ‘a’

But the second line “Set myfields = null” is not correct.

How can I solve it?

Thanks very much

I tried it with my SQL table, and it worked fine:

SQL

UPDATE MyTable SET myColumn = null WHERE Id = 3

So assuming that your column can contain null values, your code should work fine.

So what are you doing that is different from me?
