![]() If you want to output the result as true and false, you can use the IF function as follows: SELECT id,Ĭode language: SQL (Structured Query Language) ( sql ) MySQL BOOLEAN operators VALUES( 'Test Boolean with a number', 2) Consider the following example: INSERT INTO tasks(title,completed) The following query retrieves data from tasks table: SELECT id, title, completedĪs you see, the true and false were converted to 1 and 0.īecause Boolean is TINYINT(1), you can insert value other than 1 and 0 into the Boolean column. ![]() VALUES( 'Master MySQL Boolean type', true),īefore saving data into the Boolean column, MySQL converts it into 1 or 0. The following statement inserts 2 rows into the tasks table: INSERT INTO tasks(title,completed) To demonstrate this, let’s look at the following tasks table: CREATE TABLE tasks (Ĭode language: SQL (Structured Query Language) ( sql )Įven though we specified the completed column as BOOLEAN, when we show the table definition, it is TINYINT(1) as follows: DESCRIBE tasks MySQL stores Boolean value in the table as an integer. 1 0 1 0 1 0 Code language: SQL (Structured Query Language) ( sql ) MySQL BOOLEAN example See the following example: SELECT true, false, TRUE, FALSE, True, False ![]() To use Boolean literals, you use the constants TRUE and FALSE that evaluate to 1 and 0 respectively. In MySQL, zero is considered as false, and non-zero value is considered as true. To make it more convenient, MySQL provides BOOLEAN or BOOL as the synonym of TINYINT(1). MySQL does not have built-in Boolean type. ![]() Summary: this tutorial shows you how to use MySQL BOOLEAN data type to store Boolean values, true and false. ![]()
