Use ENUM  in MySQL for true   false it gives and accepts the true   false values without any extra code    ALTER TABLE  itemcategory  ADD  aaa  ENUM  false    true   NOT NULL DEFAULT  false

If you are making the boolean column as not null then the default  default  value is false  you don t have to explicitly specify it

User · Answer

You can set a default value at creation time like   CREATE TABLE Persons   ID int NOT NULL  LastName varchar 255  NOT NULL  FirstName varchar 255   Age int  Married boolean DEFAULT false

You have to specify 0  meaning false  or 1  meaning true  as the default  Here is an example   create table mytable        mybool boolean not null default 0      FYI  boolean is an alias for tinyint 1    Here is the proof   mysql gt  create table mytable       - gt           mybool boolean not null default 0     - gt         Query OK  0 rows affected  0 35 sec   mysql gt  insert into mytable    values     Query OK  1 row affected  0 00 sec   mysql gt  select   from mytable   --------    mybool    --------         0    --------  1 row in set  0 00 sec    FYI  My test was done on the following version of MySQL   mysql gt  select version     ----------------    version           ----------------    5 0 18-max-log    ----------------  1 row in set  0 00 sec
