Creating a Table in MySQL to set current date as default
Following is the syntax for creating a table and adding DEFAULT constraint to set default value −
CREATE TABLE yourTableName ( yourColumnName1 dataType not null , yourColumnName2 dataType default anyValue, . . . N );;
Let us create a table wherein we have set “employee_joining_date” with default constraint for current date as default −
mysql> create table demo43 −> ( −> employee_id int not null auto_increment primary key, −> employee_name varchar(40) not null, −> employee_status varchar(60) default "NOT JOINED", −> employee_joining_date date default(CURRENT_DATE) −> ); Query OK, 0 rows affected (0.66 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo43(employee_name,employee_status,employee_joining_date) values('John','JOINED','2020-05-10');
Query OK, 1 row affected (0.12 sec)
mysql> insert into demo43(employee_name,employee_status,employee_joining_date) values('David','JOINED','2020-10-12');
Query OK, 1 row affected (0.21 sec)
mysql> insert into demo43(employee_name) values('Bob');
Query OK, 1 row affected (0.15 sec)Display records from the table using select statement −
mysql> select *from demo43;
This will produce the following output −
+-------------+---------------+-----------------+-----------------------+ | employee_id | employee_name | employee_status | employee_joining_date | +-------------+---------------+-----------------+-----------------------+ | 1 | John | JOINED | 2020−05−10 | | 2 | David | JOINED | 2020−10−12 | | 3 | Bob | NOT JOINED | 2020−10−31 | +-------------+---------------+-----------------+-----------------------+ 3 rows in set (0.00 sec)
