属性值
类型：System.Boolean
A Boolean value that specifies the whether null values can be used in comparisons. If True, null values cannot be used in an equals or not equals comparison. The result will be null. If False (default), null values can be used in equals or not equals comparisons.
注释
The ISO ANSI standard requires that an equals (=) or not equal to (<>) comparison against a null value evaluates to FALSE.
This property overrides the AnsiNullsEnabled of the DatabaseOptions object property setting.
