Insert NULL value into database field with char(2) as type in MySQL?
Let us first create a table −
mysql> create table DemoTable658(FirstName varchar(100),value char(2)); Query OK, 0 rows affected (0.95 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable658(FirstName) values('John') ; Query OK, 1 row affected (0.19 sec) mysql> insert into DemoTable658(value,FirstName) values(default(value),'Sam'); Query OK, 1 row affected (0.23 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable658;
