This is my first article 😍, and I will discuss Varchar and NVarhcar 🤔.
Understanding the difference between VARCHAR and NVARCHAR is crucial for optimizing SQL databases, and choosing the right data type can impact storage, performance, and compatibility.
How character get store 🤔
VARCHAR: Stores non-Unicode characters, 1 byte per character
NVARCHAR: Stores Unicode characters, 2 bytes per character. It is better suited for multilingual data.
I know it's going over your head. Let me explain using an example.
Varchar Example
In Varchar I created Users table and inserts the value 'JohnDoe', which is an English string that doesn't require Unicode encoding.
NVARCHAR Example
In Nvarchar created table MultilingualUsers with a Username and inserting the value **N'ジョンド' **into the Username column.
The N prefix before the value indicates that the string is a Unicode string, which allows it to store non-English characters like Japanese, Arabic, or Chinese.
Hope it's clear till now 😍
Lets talk about Performance
Performance
VARCHAR: Better performance due to lower storage requirements for ASCII data
NVARCHAR: Slightly lower performance but essential for multilingual support.
Choose VARCHAR when optimizing for performance in single-language applications.
Happy learning!
I would be delighted to hear your ideas; please feel free to comment and share these.
