using the method bskip wbrowse

[Joao Cezar]

Hello

I have a product search filter option to choose which 1-Products in stock or 2-Products without stock or 3-Wide, tried using SetFilter () was slow network, I can not create indexes fixed or temporary, thought about using the method of bskip browse, but I can not make it work, could someone give me an example?

Follow what I'm doing:

oBrwConsul:bSkip := { | nRecs | SkipEstoq( nRadio, cAlias, nRecs ) }
...
...
...

FUNCTION SkipEstoq( nRadio, cAlias, nRecords )

LOCAL nSkipped

DEFAULT nRecords := 1

IF nRadio == 1
IF (cAlias)->PrEstq <= 0 ; IF( nRecords < 0, nRecords--, nRecords++ ); ENDIF
ELSEIF nRadio == 2
IF (cAlias)->PrEstq > 0 ; IF( nRecords < 0, nRecords--, nRecords++ ) ; ENDIF
ENDIF

nSkipped := (cAlias)->( DbSkipper( nRecords ) )

RETURN nSkipped

Joao,

Why can't you use indexes?

An index is the only way to get speed. Without an index you have to read every record--you can't make it fast.
