Does TDatabase supports SEEK LAST?

Does TDatabase supports SEEK LAST?

Postby hua » Tue Nov 07, 2023 5:03 am

Looking at TDatabase of FWH1912, I don't see support for 3rd param for dbSeek(). It is the equivalent of SEEK LAST
Is this rectified in latest version of FWH?

Please try
Code: Select all  Expand view
oDbf:DbSeek( cSeek, nil, .T. )

This works with FWH1912 also,
Don't bother if you can not find the method DbSeek()
With database class we call use any (x)Harbour function as if it is a method, if that function is linked to the application.

Note:
If you get runtime error, just include this line anywhere at the end of your prg
Code: Select all  Expand view
EXTERNAL DBSEEK

Thanks Rao,
Saved me a few keystrokes :)
I normally would type as (oDbf:cAlias)->(dbSeek(cSeek, nil, .t.))

Not only DBSEEK,
You can use any (x)Harbour function as if it is a METHOD.

If you use database objects then you can just do:

oCustomer:goBottom()

He is using database object.
But he is not looking for DbGoBottom()
He is looking for
Code: Select all  Expand view
SEEK cSeek LAST // i.e., DBSEEK( cSeek, nil, .T. )

which is totally different from "GoBottom()"
