Get Actual Execution Plan ASAP

Antonios Chatzipavlis
Monday 26 August 2019

Δεν είναι λίγες οι φορές που έχεις ένα query που παίρνει ώρα για να εκτελεστεί καθώς επιστρέφει μεγάλο αριθμό από εγγραφές και θέλεις να δεις το actual execution plan χωρίς να σε ενδιαφέρουν τα αποτελέσματα.

Σε αυτή την περίπτωση θα πρέπει να κάνεις right click on query window > select Query options > Results > Grid > Discard Results after execution.

Με αυτό δεν χρειάζεται να περιμένεις ο SSMS να δείξει τα δεδομένα έτσι κερδίζεις χρόνο.

Για παράδειγμα το παρακάτω query

select * from sales.OrderDetails as c
cross join sales.Orders 

Χωρίς να είναι ενεργοποιημένο στο lab μου κάνει 30 sec ενώ όταν είναι ενεργοποιημένο 3 sec
