Recordset comparisons

There are cases where we need to compare the content of a recordset to decide what further action is needed. Recordsets support the expected comparison operations.

To check if a <rec> record is an element of a <my_recordset> recordset, the following code can be used:

<rec> in <my_recordset>

<rec> not in <my_recordset>

Recordsets can also be compared to check if one is contained in another. To compare two recordsets, use set1 and set2:

Using set1 <= set2 and set1 < set2 returns True if all of the elements in set1 are also in set2. The < operators return False if both recordsets have the same elements.

Using set1 >= set2 and set1 > set2 returns True if all of the elements in set2 are also in set1. The > operators return False if both recordsets have the same elements.
