Delphi 3->SQL->SQLBase 7

I'm using Delphi 3.0 to ask a SQLbase 7 Database.
And I want to know if it exist a direct SQL expression to select the last one created row on a SQLBase7 Table.
Like in ACCESS :
SELECT LAST(column_name) FROM table_name;

No in real SQL such a thing doesn't exist. (Access isn't realy SQL) This is because a table can be sorted be all of its separate indices.

Now what you can do is if you know the index you sort on is the following:

SELECT
  Max(ColumnName1)
FROM
  TableName
WHERE
  ColumnName2 = (SELECT MAX(ColumnName2) FROM TableName)

This means for a database you have to define what your last item is. In the example you get the highest value of column1 where column2 is highest.

Several other solution are thinkable.

For example: Use a TTable component and do Table.Last; (this sometimes can be very slow though, watch the SQL monitor)

(P.S. Does your database system have stored procedure, I have a solution using these)
