Less Than Or Equal [<=] link
The result set from a Less Than Or Equal link includes all records in which
the linked field value in the primary table is less than or equal to the linked
field value in the lookup table. The example here is identical to the example
for the Less Than link, except that it uses the Less Than Or Equal link:
SELECT Manager.'Last Name',
Manager.'Salary',
SalesRep.'Last Name',
SalesRep.'Salary'
FROM 'Manager' Manager,
'SalesRep' SalesRep
WHERE Manager.'Salary' <=
SalesRep.'Salary'
