Yog hais tias lub sij hawm sib cav yog NULL, xaiv () thaiv kom txog thaum ib qho kev tshwm sim ua rau ib qho ntawm lub qhov ncauj qhov ntswg rov qab nrog tus nqi siv tau (tsis yog xoom).
Qhov sib thooj, kev xaiv thaiv yog dab tsi?
Ib hom kev txiav txim plaub ntug uas tus account los yog cov khoom raug xaiv nyob rau hauv ib qho kev txiav txim ua ntu zus. Thaum thawj yam khoom nyob rau hauv lub thaiv tau xaiv, ces qhov sib npaug ntawm cov thaiv yuav tau xaiv.
Tsis tas li ntawd, koj yuav xaiv cov ntawv thaiv li cas? Yog tias koj xav xaiv ib qho thaiv cov ntawv siv cov keyboard, ua raws li cov kauj ruam no:

- Qhib Properties palette.
- Nyem lub khawm xaiv ceev kom qhib lub Quick Select dialog box.
- Rau Hom Hom, xaiv Block Reference.
- Rau Cov Khoom, xaiv Lub Npe.
- Rau tus neeg teb xov tooj, xaiv = Equals (lub neej ntawd).
- Rau Tus Nqi, xaiv qhov thaiv lub npe los ntawm daim ntawv teev npe poob.

Block sampling yog dab tsi?
Thaiv sampling yog a kev ua piv txwv txheej txheem siv nyob rau hauv auditing, qhov uas ib tug sequential series ntawm kev xaiv yog ua. Piv txwv li, tus kws tshuaj ntsuam xyuas xaiv siv block sampling txhawm rau tshuaj xyuas cov neeg siv khoom xa tuaj, thiab npaj siab yuav xaiv 50 daim ntawv xa nyiaj. Txawm li cas los xij, ib txoj hauv kev xaiv ntau dua yuav ua tau txoj haujlwm zoo dua kev ua piv txwv tag nrho cov pejxeem.
