How to select between/before/after dates in MySQL conditionally?
Following is the syntax −
select *from yourTableName where yourColumnName1 < yourValue1 AND (yourColumnName2 > yourValue2 OR yourColumnName2 is null);
Let us create a table −
mysql> create table demo35 −> ( −> id int NOT NULL AUTO_INCREMENT PRIMARY KEY, −> joining_date date, −> relieving_date date −> ); Query OK, 0 rows affected (3.88 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo35(joining_date,relieving_date) values('2020−01−10','2020−07−11');
Query OK, 1 row affected (0.15 sec)
mysql> insert into demo35(joining_date,relieving_date) values('2020−05−07','2020−12−08');
Query OK, 1 row affected (0.17 sec)
mysql> insert into demo35(joining_date,relieving_date) values('2020−04−11','2020−09−18');
Query OK, 1 row affected (0.14 sec)
mysql> insert into demo35(joining_date,relieving_date) values('2020−03−12','2020−10−01');
Query OK, 1 row affected (0.13 sec)Display records from the table using select statement −
mysql> select *from demo35;
This will produce the following output −
+----+--------------+----------------+ | id | joining_date | relieving_date | +----+--------------+----------------+ | 1 | 2020−01−10 | 2020−07−11 | | 2 | 2020−05−07 | 2020−12−08 | | 3 | 2020−04−11 | 2020−09−18 | | 4 | 2020−03−12 | 2020−10−01 | +----+--------------+----------------+ 4 rows in set (0.00 sec)

mysql> select *from demo35 −> where −> joining_date < '2020−05−11' AND −> (relieving_date > '2020−08−10' OR relieving_date is null);
This will produce the following output −
+----+--------------+----------------+ | id | joining_date | relieving_date | +----+--------------+----------------+ | 2 | 2020−05−07 | 2020−12−08 | | 3 | 2020−04−11 | 2020−09−18 | | 4 | 2020−03−12 | 2020−10−01 | +----+--------------+----------------+ 3 rows in set (0.00 sec)
