SQL Null or Empty - How to Check for Null or Empty Column in SQL Server - Quick Tips Ep42

VERY HELPFUL, THANK YOU ✌

Thanks Joey for providing the information that I have needed indeed....

In our code of application we have written many column is not null condition we are getting null value in that place because of this database issue.

is the any function helpfull to enter the single quote value as null value to process to the column.

Is there an parameter level setting while entering single quote it need to send the insert or update as null in the column.

Thanks Joey!

Very well. Thanks man. Great video. :)

It looks like this is for a string field...How would this work for numeric and date fields? Thanks!

Great stuff! I wanted to know how you would go about updating a table with multiple columns having Null values with the integer "0". Thanks!

Is there an easy way to check for null values in all the columns of a table?

Thank you!

Thanks a lot, it is easy to understand.

Hey if I have multiple columns like 100 columns and I want to test IS Null. How would it be possible? I can't do WHERE * ISNULL

How to replace null values with another thing

This is nice and thank you for taking the time to make a video but it instantly makes the query non SARGable (unable to do index seeks/range scans) because it has to express the ISNULL formula against every row in the column (i.e. table or index scan at its best) to first convert the NULLs to empty strings and then finally does the comparisons. The OR method is actually better from a performance point of view but even it has a performance issue.

You said: "Every time it sees a Null, it's going to turn it into an empty string." But I didn't see vendor name "Intel" change into an empty string. Why did that stay Null?

How can i make the empty cells into null?

thank you nice video

Thank you!

Great stuff...I will be back to this channel for all my SQL questions

Great content, right to the point. Thanks a lot Joey!

I like yr video..short!!!

please show about constraint

please show about constraint

you best

Not really gud alternative man..
When ever you use isnull to make this kind kind of comparison the and you have got index on that column then the index seek will convert to index scan

Great videos short and sweet.. right to the point.. very helpful thks
