May 7, 2018 MySQL - BOOL. Syntax, BOOL. Data, Boolean data. Range, -128 to 127 and NULL. Values TRUE and FALSE (MySQL keywords) are
From MySQL manual, it says: BOOL, BOOLEAN. These types are synonyms for TINYINT(1). A value of zero is considered false. Nonzero values are considered true: I created a BOOLEAN column with 0 as the default value. Then I update the value to 2. Logically, I would expect MySQL to accept either 0 or 1 since it is a boolean.
Well i am new to MySql so i will be happy is someone can help me sort it out. I am migrating data from Microsoft SQL Server 7 to MySql 5. while i realy dont know how to handle the BOOLEAN fields is MySql or how to define them. Any help will be appriciated. Thanks!
Let us create a demo table for our example − mysql> create table countBooleanFieldDemo -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentFirstName varchar(20), -> isPassed tinyint(1) -> ); Query OK, 0 rows affected (0.63 sec) 2005-01-07 2021-04-09 Since the theme of my week appears to be database interactions (having looked at index structure query-performance on "membership" tables and prepared statements in the JDBC driver), I figured I would end the week on more database-related "hot take": I no longer use BIT columns to store "Boolean" data in MySQL. Instead, I use a TINYINT column.. CAUTION: There is no "right" answer on this topic To make it more convenient, MySQL provides BOOLEAN or BOOL as the synonym of TINYINT (1). In MySQL, zero is considered as false, and non-zero value is considered as true. To use Boolean literals, you use the constants TRUE and FALSE that evaluate to 1 and 0 respectively. See the following example: Introduction to MySQL Boolean. There is none of the built-in datatype present in MySQL for boolean values.

MySQL does have a boolean data type. However, it is just a synonym for TINYINT which is a numeric field. A common alternative is to use a BIT field.

A common alternative is to use a BIT field. A BIT data type is used to store bit values from 1 to 64. So, a BIT(1) field can be used for booleans, providing 1 for TRUE and 0 for FALSE.

MySQL中的Boolean类型（没有Boolean） 这里记录一个在项目中开发的小事件：领导要求某个字段在mysql中存储类型为Boolean，并在其查看字段为tinyint时被小怼了一句（字段类型怎么还没有改成Boolean类型） 前台的参数类型大概如下： { “xxx”:“xxx”, “xxx”:“xxx”, “enable”:true或者false } 对于前台传递的 Tinyint(1) field type for boolean data in MySQL table To store Boolean data, MySQL uses Tinyint(1) field type. We can store, update or delete Boolean data by using Tinyint(1) field type.
