stencilz Posted February 21, 2007 Report Share Posted February 21, 2007 pastulbs jautājums :) ja man ir tabula ar 40 kolonnām, tad kaut ko būtiski maina ja es selektējot izvēlos visu ar * vai atlasu tikai sev nepieciešamās 8 kolonnas? Link to comment Share on other sites More sharing options...

stencilz Posted February 21, 2007 Author Report Share Posted February 21, 2007 mazāk laika aizņem izpildīšanai? Link to comment Share on other sites More sharing options...
andrisp Posted February 21, 2007 Report Share Posted February 21, 2007 Ne tikai, mazāk arī dati jāpārsūta no mysql uz apache, kā arī mazāk atmiņa tiks aizņemta, kad saņemsi rezultātu, bet nu tas tā. Link to comment Share on other sites More sharing options...
stencilz Posted February 21, 2007 Author Report Share Posted February 21, 2007 (edited) nu labi, paldies par atbildēm. tas būtu labāk arī ja selektotu 39 kolonnas no 40? Edited February 21, 2007 by stencilz Link to comment Share on other sites More sharing options...
