What is Longtext data type in MySQL?

LONGTEXT can store the maximum characters among all four, up to 4,294,967,295 characters i,e 4,294,967,295 bytes or 4GB. This is more than enough storage for any long-form text strings. For example, a book that MEDIUMTEXT can’t hold can be stored using LONGTEXT. LONGTEXT takes 4-Bytes overhead.

What is Longtext data type?

Long Text In Access web apps, the Long Text field can store up to 2^30-1 bytes, and is equivalent to the SQL Server data type of nvarchar(max). If you want, you can set a character limit to prevent your users from using the full capacity of the field. Its SQL Server equivalent is nvarchar, with length from 1 to 4000.

What is SQL Longtext?

LONGTEXT. Holds a string with a maximum length of 4,294,967,295 characters. LONGBLOB. For BLOBs (Binary Large Objects). Holds up to 4,294,967,295 bytes of data.

What is Mediumtext?

MEDIUMTEXT: 16,777,215 – 16 MB The MEDIUMTEXT data object is useful for storing larger text strings like white papers, books, and code backup. These data objects can be as large as 16 MB (expressed as 2^24 -1) or 16,777,215 characters and require 3 bytes of overhead storage.

What is JSON data type in MySQL?

MySQL supports a native JSON data type defined by RFC 7159 that enables efficient access to data in JSON (JavaScript Object Notation) documents. JSON documents stored in JSON columns are converted to an internal format that permits quick read access to document elements.

What is Type BLOB?

A BLOB (binary large object) is a varying-length binary string that can be up to 2,147,483,647 characters long. Like other binary types, BLOB strings are not associated with a code page. In addition, BLOB strings do not hold character data.

What is BLOB data type in MySQL?

A BLOB is a binary large object that can hold a variable amount of data. The four BLOB types are TINYBLOB , BLOB , MEDIUMBLOB , and LONGBLOB . They have the binary character set and collation, and comparison and sorting are based on the numeric values of the bytes in column values.

Should I use text or varchar?

If it has variable length with a well defined upper limit then use varchar . If it’s a big chunk of text that you have little control over then text would be probably your best bet.

What are the types of data types?

What are Data Types and Why are They Important?

• Integer (int)
• Floating Point (float)
• Character (char)
• String (str or text)
• Boolean (bool)
• Enumerated type (enum)
• Array.
• Date.

What is the difference between BLOB and TEXT?

BLOB is used for storing binary data while Text is used to store large string. BLOB values are treated as binary strings (byte strings). They have no character set, and sorting and comparison are based on the numeric values of the bytes in column values. TEXT values are treated as nonbinary strings (character strings).

What is varchar in MySQL?

Varchar in MySQL is a data type used for storing text whose length can have a maximum of 65535 characters. The varchar columns in the table are of variable length string that can hold either numeric or character or both.

What is JSON format?

JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).

What are the different types of text in MySQL?

MySQL provides four TEXT types: TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. The following shows the size of each TEXT type with the assumption that we are using a character set that takes 1 byte to store a character

How big is a medium text string in MySQL?

The MEDIUMTEXT data object is useful for storing larger text strings like white papers, books, and code backup. These data objects can be as large as 16 MB (expressed as 2^24 -1) or 16,777,215 characters and require 3 bytes of overhead storage. The LONGTEXT data object is for use in extreme text string storage use cases.

Which is the smallest data type in MySQL?

The Basics Of MySQL TEXT Data Type Introduction to MySQL TEXT data type TINYTEXT – 255 Bytes (255 characters) TEXT – 64KB (65,535 characters) MEDIUMTEXT – 16MB (16,777,215 characters) LONGTEXT – 4GB (4,294,967,295 characters)

How big is the LongText object in MySQL?

LONGTEXT: 4,294,967,295 characters – 4 GB The LONGTEXT data object is for use in extreme text string storage use cases. It is a viable option when the MEDIUMTEXT object is not big enough. Computer programs and applications often reach text lengths in the LONGTEXT range.
