Get the number of days between current date and date field?
To get the number of days between current date and date field, the syntax is as follows −
SELECT DATEDIFF(CURDATE(),STR_TO_DATE(yourColumnName, '%d-%m-%Y')) AS anyAliasName FROM yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table DateDifferenceDemo -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> ArrivalDate varchar(100) -> ); Query OK, 0 rows affected (0.55 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into DateDifferenceDemo(ArrivalDate) values('12-10-2011'); Query OK, 1 row affected (0.14 sec) mysql> insert into DateDifferenceDemo(ArrivalDate) values('01-12-2013'); Query OK, 1 row affected (0.07 sec) mysql> insert into DateDifferenceDemo(ArrivalDate) values('31-10-2014'); Query OK, 1 row affected (0.08 sec) mysql> insert into DateDifferenceDemo(ArrivalDate) values('12-04-2016'); Query OK, 1 row affected (0.09 sec) mysql> insert into DateDifferenceDemo(ArrivalDate) values('20-08-2018'); Query OK, 1 row affected (0.07 sec) mysql> insert into DateDifferenceDemo(ArrivalDate) values('11-03-2019'); Query OK, 1 row affected (0.07 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from DateDifferenceDemo;
Here is the output −
+----+-------------+ | Id | ArrivalDate | +----+-------------+ | 1 | 12-10-2011 | | 2 | 01-12-2013 | | 3 | 31-10-2014 | | 4 | 12-04-2016 | | 5 | 20-08-2018 | | 6 | 11-03-2019 | +----+-------------+ 6 rows in set (0.00 sec)
The following is the query to get number of days between current date and date field −
mysql> SELECT DATEDIFF(CURDATE(),STR_TO_DATE(ArrivalDate, '%d-%m-%Y')) AS NumberOfDays from DateDifferenceDemo;
Here is the output −
+--------------+ | NumberOfDays | +--------------+ | 2708 | | 1927 | | 1593 | | 1064 | | 204 | | 1 | +--------------+ 6 rows in set (0.00 sec)
