How can Oracle query data for a specific time period?

In Oracle, you can use the SELECT statement with the WHERE clause to query data within a specific time period. Here is an example:

If you have a table called “orders” that includes a column named “order_date” indicating the date of the orders, you can query for data within a specific time period (such as from January 1, 2021, to December 31, 2021) using the following query statement:

SELECT * FROM orders
WHERE order_date >= TO_DATE('2021-01-01', 'YYYY-MM-DD')
AND order_date <= TO_DATE('2021-12-31', 'YYYY-MM-DD');

In the above query, use the TO_DATE function to convert the string to a date type, and then filter out the data that meets the criteria using the >= and <= operators. Adjust the date format and table name according to your actual situation.
