Question

Is there a way to create UPDATE stored_procedure with parameters like:

@param1 int = null,
@param2 int = null,
@param3 nvarchar(255) = null,
@param4 bit = null,
@id int

and with UPDATE statement which will update only fields which are not NULL

so if I execute

spUpdateProcedure @param1=255, @id=1

if will update record @id=1 but it will change only field @param1 and will ignore changes to other @param2,3,4.

In other words, it wont change value for null in @param2,3,4

Thanks.

UPDATE YourTable
    SET Column1 = COALESCE(@param1, Column1),
        Column2 = COALESCE(@param2, Column2),
        ...
    WHERE id = @id
