Difference between Char and Varchar

Difference between Char and Varchar

When it comes to database data types, there are many options to choose from. However, two of the most common data types are char and varchar. Both have their own benefits and drawbacks, so it can be difficult to decide which is the best option for your specific situation. In this blog post, we will take a closer look at the difference between char and varchar, so you can make an informed decision about which one to use.

What is Char?

Char SQL code is a type of code that is used to store information in a database. This code is typically used to store character data, such as names or addresses. Char SQL code can be used to store up to 8,000 characters in a single field. Char SQL code is often used in conjunction with other types of SQL code, such as VARCHAR and TEXT. Char SQL code can be used to create fields that are both easy to search and easy to update. Char SQL code is an important tool for any programmer who needs to store data in a database.

What is Varchar?

Varchar is a data type in SQL code that stands for “variable character.” It is used to store strings of characters, such as names or addresses. Varchar values can be any length, from zero characters up to the maximum specified length. For example, a Varchar(100) column can hold up to 100 characters. Varchar columns are often used for storing text data, such as comments or descriptions. Varchar columns are also sometimes used for storing serialized data, such as JSON objects. Varchar SQL code is an essential part of many databases and helps to ensure that data is stored accurately and efficiently.

Difference between Char and Varchar

Char and Varchar are both used to store character strings in databases, but there are some important differences between them. Char is a fixed-length string data type, while Varchar is a variable-length string data type. This means that, when using Char, the string will always take up the same amount of space, regardless of how many characters it contains.

Varchar, on the other hand, will only use as much space as necessary to store the string. In addition, Char strings are padded with spaces to fill the allotted space, while Varchar strings are not. As a result, Char is generally more efficient for storing short strings, while Varchar is more efficient for storing longer strings.


In conclusion, Char is a fixed-length data type that can store only characters, while Varchar is a variable-length data type that can store both characters and numbers. The main difference between the two data types is that Char can hold a maximum of 255 characters, while Varchar can hold up to 8000 characters. So which one should you use in your SQL statements? That depends on the size and complexity of your data. If you need to store large amounts of text or binary data, then Varchar is the better choice. Otherwise, Char will work just fine for most purposes.
