Boolean vs. tinyint(1) in MySQL: Which Should I Use for Boolean Values?

Boolean vs tinyint(1) for Boolean Values in MySQL

When working with boolean values in MySQL, the choice between using the boolean data type and the tinyint(1) data type can arise. While they may seem like different options, they are essentially equivalent.

MySQL recognizes tinyint(1) as a boolean datatype. Both boolean and tinyint(1) can store values of 0 (false) and 1 (true). They can be used interchangeably, as MySQL automatically converts between them.

Usage Example:

To illustrate this, consider the following example:

CREATE TABLE my_table (
  is_active boolean,
  is_admin tinyint(1)
);

INSERT INTO my_table (is_active, is_admin) VALUES (true, 1);
SELECT * FROM my_table WHERE is_active = is_admin;

In this example, the columns is_active and is_admin are both used to store boolean values. The INSERT statement inserts a new row with is_active set to true (1) and is_admin set to 1 (true). The SELECT statement retrieves the row where is_active and is_admin are equal, which will return the row just inserted.

Conclusion:

When storing boolean values in MySQL, both boolean and tinyint(1) can be used effectively. As they are synonyms, choosing between them is a matter of personal preference.
