Definition and Usage
NOW() returns the current date and time.
Syntax
Example
The following SELECT statement:
SELECT NOW(),CURDATE(),CURTIME() |
will result in something like this:
NOW() | CURDATE() | CURTIME() |
2008-11-11 12:45:34 | 2008-11-11 | 12:45:34 |
Example
The following SQL creates an "Orders" table with a datetime column (OrderDate):
CREATE TABLE Orders
(
OrderId int NOT NULL,
ProductName varchar(50) NOT NULL,
OrderDate datetime NOT NULL DEFAULT NOW(),
PRIMARY KEY (OrderId)
) |
Notice that the OrderDate column specifies NOW() as the default value. As a result, when you insert a row into the table, the current date and time are automatically inserted into the column.
Now we want to insert a record into the "Orders" table:
INSERT INTO Orders (ProductName) VALUES ('Jarlsberg Cheese') |
The "Orders" table will now look something like this:
OrderId | ProductName | OrderDate |
1 | Jarlsberg Cheese | 2008-11-11 13:23:44.657 |
