Ur god in sql field####
Nice video.
thank you for these videos.
i have a general knowledge in computing. do you provide tutorials lessons for those who want to be SQL certified?
Concept explained clearly. When user goes to create index in designer menue are changed from Server versions. I think you may be using 2005 or 2008. I am using SQLEXPRESS2012 and it directly defaults the index to Non-Clustered if there are no indexes'. Also if you could mention what would be default for ASC or DES for a column. Pl note I am suggesting not criticizing. I love your videos. I enjoyed this video. Thanks a bunch
you are amazing!!
thank you very much sir
Venkat,
What if we have 2 tables with same structure & 2 million records in each.
one have clustered index & other don't have any index.
If we write select * query without where clause? what will be the result ?
I mean which will give data fast if we are not using where clause in query ?
You should have mentioned about the binary search that takes place on the separate table that is created with
sorted key values
Its a B-TREE not a BST
Pretty good video! even nowdays, pretty easy to understand! Only downside is that there is no examples with an without what the performance is and the gain. Though that is not the goal of the video.
thank you very much
very nice tutorial
Great tutorial however i still wanted to understand how sql seeks the index as it doesn't have eyes like we have to see in Book Index :) it still need to go through row by row to fulfill the where clause right? I know not correct but I'm not convinced yet. Also if i want to fetch all records from table then i dont need to have indexes right?
Thank you
In the Non-Clustered Index table shown at 5:00 what if there are duplicate values in salary, does the database attach multiple addresses to the same salary? (how is that done? like a dictionary with salary as key and list of addresses as value?)
Thanks
