SELECT FIRST(ID) FROM myTable ORDER BY FIRST(ID);or
SELECT MIN(ID) FROM myTable;If your database requires a time/date stamp then the min and max functions on the time/date field would work. Like:
SELECT MIN(DateTimeField) FROM myTable;Note that the above SQL only returns the value of a single field.
Another way you could write the SQL to return more than just a single field is with the TOP function. To get the first record:
SELECT TOP 1 * FROM myTable ORDER BY ID;To get the last record:
SELECT TOP 1 * FROM myTable ORDER BY DateTimeField DESC;You could make two queries. One called GetFirstAsset and one call GetLastAsset, then execute these queries (Stored Procedures) from the Visual Basic code.
