If you ever want to use TOP keyword with dynamic number
DECLARE @count int
SET @count=10

SELECT TOP @count from Table

This will throw error

Try with
SELECT TOP (@count) from Table

Belated Anniversary wishes to both of you :)

Please find below one of the concept which I found to be very useful in one of our requirement.

When a table is having unique index and if an attempt is made to insert duplicate data an error is thrown. Conventional method to insert data into such table from another table is to either use “NOT IN” or “NOT EXISTS”. But if the table, to which data insertion has to be made, has billions of records, there may be performance issues.
In such cases “IGNORE_DUP_KEY” property can be used. By default, for a unique index the property is set to OFF. When this property is set to ON, it will issue a warning message when a duplicate key is inserted and the particular row is ignored and also continues with the transaction. There was a good performance by using this property since %age of duplicates were less

Happy Aniversary to both of you!

My first suggestion is not related to SQL.
As you have earlier recored one video regarding how you record these videos. My Suggestion is related to this. Can you record a video about how you capture this image? (As you already told, this is not photoshoped or modified) :)

Well, I will submit list of suggestion later after checking existing videos. (Related to SQL, this time :) )

Recently came to know very interesting bit when we do the “select count(*) from table”. Optimiser select very interesting plans when we have index on table and there there is no index.

I always thought it will scan the table but I was wrong it does index scan when have index on table.

I thought it is very interesting and hope you feel the same would share it.Please let me know if need I can send you demo code.

Anyway Happy Wedding Anniversary.

Thanks

Here my two suggestions for videos SQL in sixty seconds.

1- Get the max between multiple columns
exemple , my table contain 4 columns Id, Date1, Date2 and Date3 and i want get the Max bettween then.

I find solution very simple , do this request

SELECT id, (SELECT MAX([Value]) FROM
( SELECT Date1 AS [Value]
UNION ALL
SELECT Date2
UNION ALL
SELECT Date3
) AS UnionSetMax
) AS MaxDate

The column MaxDate Return the Max date between date1, date2 and date3

2- Planifie Backup database with Script and Task Sckeduler

create sql file “scriptbackup.sql” with content this cript
Backup Database MyDatabaseTo Disk = ‘E:\Backup_Bdd\MyDatabase.bak’

create file .bat “lancherbackup.bat” with content this command
sqlcmd -E -S [Sever] -i E:\Backup_Bdd\scriptbackup.sql

with the task sckeduler planifie the execution of the lancherbackup.bat.

thanks

Happy Wedding Anniversary! :)

Please find below one of the ideas on which possibly many SQL Server beginners have issues with -

Fixing Orphaned users after Restore on New instance.

Scenario: During Upgrades or Migrations, often we would have to take backups of the current Databases and Restore the same on the New Instance. When some of the beginners do that, they often forget or are not aware of the fact that there may be users which existed in the previous instance and they do not exist on the new instance.

A quick video on how to fix these orphaned users would be a great tutorial that would help them keep that in mind. :)

Thanks.

First of all Wedding day wishes to my SQL Guru. Once again we check with all the existing SQL sixty video and then suggest a topic with descriptive.

Let me take the privilege of commenting first and suggest few topics for SQL in sixty seconds.

Topics :

2. Explaining common types of deadlock
3. Monitoring Tempdb space
4. Deadlock Graph event in SQL Trace
5. How to view the SQL Server Error Log
