Question

The date column in T (for Assignment 01) is of type datetime. What SQL function can we use to insert a datetime into the table?

Answer 1

To insert a datetime into a SQL table, you can use the NOW() function for the current date and time, or provide a specific date and time formatted as 'YYYY-MM-DD HH:MM:SS'. Different SQL dialects may have their own syntax for datetime values.

Step-by-step explanation:

To insert a datetime into a SQL table, you can use the NOW() function if you want to insert the current date and time. This function is used in an INSERT statement to add a new row of data into a table with a datetime column.

Here's an example:

INSERT INTO T(Assignment01) VALUES(NOW());

If you want to insert a specific date and time, you have to ensure the value is in the correct format supported by your SQL database, typically 'YYYY-MM-DD HH:MM:SS'. An example of this would be:

INSERT INTO T(Assignment01) VALUES('2023-05-20 14:30:00');

Note that SQL databases may have different requirements or functions for handling datetime values depending on the specific SQL dialect (e.g., MySQL, SQL Server, PostgreSQL).
