How to check if a datetime value equals tomorrows date in MySQL?

For this, you can use DATEDIFF(). Let us first create a table −

mysql> create table DemoTable
   -> (
   -> ShippingDate datetime
   -> );
Query OK, 0 rows affected (0.90 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('2019-07-01');
Query OK, 1 row affected (0.29 sec)

mysql> insert into DemoTable values('2019-07-02');
Query OK, 1 row affected (0.15 sec)

mysql> insert into DemoTable values('2019-07-03');
Query OK, 1 row affected (0.32 sec)

mysql> insert into DemoTable values('2019-07-04');
Query OK, 1 row affected (0.15 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

+---------------------+
| ShippingDate        |
+---------------------+
| 2019-07-01 00:00:00 |
| 2019-07-02 00:00:00 |
| 2019-07-03 00:00:00 |
| 2019-07-04 00:00:00 |
+---------------------+
4 rows in set (0.00 sec)

Following is the query to check if datetime equals tomorrows date in MySQL or not −

mysql> select *from DemoTable
   -> WHERE DATEDIFF(ShippingDate, DATE_ADD(CURDATE(), INTERVAL 1 DAY)) = 0;

This will produce the following output displaying tomorrows date 2019-07-02 was one of the dates in the table −

Output

+---------------------+
| ShippingDate        |
+---------------------+
| 2019-07-02 00:00:00 |
+---------------------+
1 row in set (0.08 sec)
