Description
TVariantRelationship describes the results of comparing two Variants.
TVariantRelationship describes the relationship between two Variant values. The following table lists the possible values:
| Value | Meaning |
|---|---|
|
vrEqual |
A is equivalent to B. Note that two NULL Variants are considered equal, and two empty Variants are considered equal, but a NULL Variant does not equal an empty Variant. |
|
vrLessThan |
A is less than B. |
|
vrGreaterThan |
A is larger than B. |
|
vrNotEqual |
A and B are not equal, but the values are such that they can't be ordered relative to each other. For example, this describes the relationship when either A or B is empty or NULL, and the other one is not. |
