BOOLEAN in mysql code example
Example 1: mysql bool
-- In Mysql, BOOL and BOOLEAN are both aliases for TINYINT.
-- zero is considered false.
-- any non-zero value is considered true.
Example 2: mysql is in list
SELECT
column1,column2,...
FROM
table_name
WHERE
(expr|column_1) IN ('value1','value2',...);
Example 3: mysql in
SELECT
column1,column2,...
FROM
table_name
WHERE
column1 IN ('value1','value2',...);
Example 4: boolean mysql
-- MySQL doesn't have a boolean. Instead, use TINYINT. BOOL and BOOLEAN
-- are aliases to TINYINT. 0 is true, while 1 is false for TINYINT.
-- You can also use TRUE, FALSE, true, false, True, or false as
-- aliases for 0 and 1 respectively.
CREATE TABLE IF NOT EXISTS boolTest (
thisFieldIsTrue TINYINT DEFAULT 0 -- True by default
thisFieldIsFalse TINYINT DEFAULT 1 -- False by default
thisIsAlsoTru BOOL DEFAULT True -- True by default, see above for alternates to True and Bool
)
Example 5: boolean mysql
SELECT true, false, TRUE, FALSE, True, False;
-- 1 0 1 0 1 0
