constraint on a field in a table, then this table may not contain 2 rows or more of the field value is unknown row.3. In a filter, if you compare two null values, the resulting value is unknown, but will still be treated as false.4, in unique constraints, set operations (such as union and except), sorting, grouping operations, the two null values are considered equal.⑴ this way, in a column with a unique constraint, you cannot insert two rows in the table that have null for the column valueThe
