It should be noted that the MYSQL TEXT data is not kept in the memory of the database server. Also, different from VARCHAR and CHAR, MySQL does not delete or swabspaces when we insert or fetch columns with TEXT data values. Unlike VARCHAR and CHAR types, for a column having TEXT data type you do not need to state a string character length for using it. It is supported in applications and computer programs.
#MYSQL STRING LENGTH CODE#
MEDIUMTEXT has a size of string characters up to 16,777,215 which is helpful to store longer text strings such as books, code backup, and white papers.The TEXT data type has a size of string characters upto 65,535 bytes to manage classic long-form contents of the text.It holds max 255 characters length of string that supports to build up storage for small info strings resourcefully. Here, TINYTEXT is the smallest TYPE OF TEXT kind and defines the identical character length as MySQL VARCHAR type.For info, CHAR contains a fixed length of strings defined from 0 to 255 and VARCHAR has a flexible length string defined from 0 to 65535. This data type TEXT can be said just like the MySQL VARCHAR but the former column do not exist with DEFAULT values as succeeding ones. These all types of TEXT are identical to each other but differ with a slight variation that is with the maximum capacity or volume of data values each one can hold. They are TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT. In actual, this TEXT data type for a column is composed of four categories. On the ordering of its character set, the evaluations and sorting are built. MySQL TEXT is a standard data type for storing special character strings with maximum sizes or as defined. In the above code, when executed it will add a new column ColName (specify any column name as desired) with data type as TEXT but after the column named Description that was created by the previous query while creating table. Here, we have added some columns with TEXT and other data types where ’ forms’ says you can add other forms of TEXT that are explained later in the table with name as TableName(provide table name as desired).Īgain, the use of TEXT with ALTER keyword by the below query syntax:ĪDD COLUMN ColName TEXT NOT NULL AFTER Description
We can use TEXT while creating a table using the following query structure:ĬREATE TABLE TableName (ID INT PRIMARY KEY AUTO_INCREMENT, Title VARCHAR (255) NOT NULL, Description TEXTNOT NULL) We have introduced a basic syntax code succeeding to illustrate the TEXT data type in MySQL.
