How to use the CURDATE function in MySQL to get the current date
The CURDATE function is a very useful function in MySQL for getting the current date. In databases, it is often necessary to use the current date to perform various operations, such as recording the current date when inserting or updating data. The CURDATE function can help us get the current date very conveniently, making the operation simpler and more efficient.
Using the CURDATE function is very simple, just call it in the query. The following is an example of using the CURDATE function to obtain the current date and perform a query:
SELECT * FROM table_name WHERE date_column = CURDATE();
In the above code, table_name is your table name, and date_column is the date column name you need to compare. Using the CURDATE function will return the current date, compare it with date_column, and only return records that meet the conditions.
The CURDATE function can also be used to insert or update data. The following is an example of inserting the current date using the CURDATE function:
INSERT INTO table_name (date_column) VALUES (CURDATE());
The above code will insert the current date in the date_column column in the table_name table. No need to enter the date manually, the CURDATE function automatically gets the current date and inserts it.
The CURDATE function can not only obtain the current date, but can also be adjusted through some parameters. For example, CURDATE() - INTERVAL 1 DAY can be used to get the date of the previous day, and CURDATE() INTERVAL 1 DAY can be used to get the date of the next day. You can adjust it according to actual needs and use the CURDATE function more flexibly.
In addition to the CURDATE function, MySQL also provides some other similar date and time functions, such as the NOW function for getting the current date and time, the CURTIME function for getting the current time, etc. These functions can be used in different scenarios, and you can choose the appropriate function according to your needs.
In short, the CURDATE function is a convenient and efficient function in MySQL for getting the current date. You can use the CURDATE function when querying, inserting or updating data, making the operation simpler and more accurate.
