Grab where current date and the day before with MySQL?
You can grab the current date with CURDATE() and the day before with MySQL using DATE_SUB() with INTERVAL 1 DAY. The syntax is as follows:
SELECT DATE_SUB(CURDATE(),INTERVAL 1 DAY);
The syntax is as follows to get curdate and the day before with date_sub().
SELECT *FROM yourTableName WHERE yourColumnName = CURDATE() OR yourColumnName = DATE_SUB(CURDATE(),INTERVAL 1 DAY);
To understand the above syntax, let us create a table. The query to create a table is as follows:
mysql> create table ProductDemo -> ( -> Id int NOT NULL AUTO_INCREMENT, -> ProductName varchar(20), -> ProductOfferDate datetime, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.54 sec)
Insert some records in the table using insert command. Here, we have added the products and the product offer date. The query is as follows:
mysql> insert into ProductDemo(ProductName,ProductOfferDate) values('Product-11','2017-05-21');
Query OK, 1 row affected (0.25 sec)
mysql> insert into ProductDemo(ProductName,ProductOfferDate) values('Product-22','2019-01-15');
Query OK, 1 row affected (0.16 sec)
mysql> insert into ProductDemo(ProductName,ProductOfferDate) values('Product-21','2019-01-14');
Query OK, 1 row affected (0.14 sec)
mysql> insert into ProductDemo(ProductName,ProductOfferDate) values('Product-91','2018-10-23');
Query OK, 1 row affected (0.26 sec)
mysql> insert into ProductDemo(ProductName,ProductOfferDate) values('Product-133','2019-01-24');
Query OK, 1 row affected (0.13 sec)
Display all records from the table using select statement. The query is as follows:
mysql> select *from ProductDemo;
The following is the output:
+----+-------------+---------------------+ | Id | ProductName | ProductOfferDate | +----+-------------+---------------------+ | 1 | Product-11 | 2017-05-21 00:00:00 | | 2 | Product-22 | 2019-01-15 00:00:00 | | 3 | Product-21 | 2019-01-14 00:00:00 | | 4 | Product-91 | 2018-10-23 00:00:00 | | 5 | Product-133 | 2019-01-24 00:00:00 | +----+-------------+---------------------+ 5 rows in set (0.00 sec)
The following is the query to grab the product with current date and the day before:
mysql> select *from ProductDemo -> where ProductOfferDate = CURDATE() OR ProductOfferDate = date_sub(curdate(),interval 1 day);
The following is the output:
+----+-------------+---------------------+ | Id | ProductName | ProductOfferDate | +----+-------------+---------------------+ | 2 | Product-22 | 2019-01-15 00:00:00 | | 3 | Product-21 | 2019-01-14 00:00:00 | +----+-------------+---------------------+ 2 rows in set (0.00 sec)
