Recordset

The ODBC recordset is the set of records from the datasource. If no filter is present, it encompasses the whole datasource. If a filter is present, it is only the subset of records for which the filter condition is satisfied.

A filter is made up of a condition and a parameter that the '?' in the condition stands for. Some examples :

condition (filter) paramter result : only records
NAME like ? du* whose NAME starts with "du"
GROUP = ? 501 whose GROUP = 501
NAME < ? d whose first character in NAME is after 'd'

The result can be sorted.
