To compare dates in MySQL except time portion of a datetime field, you can use DATE() function. The syntax is as follows −
select *from yourTableName where date(yourColumName) = yourDate;
To understand the above concept, let us create a table. The query to create a table is as follows −
mysql> create table ComparingDate −> ( −> Name varchar(100), −> Login datetime −> ); Query OK, 0 rows affected (0.50 sec)
Now you can insert some records in the table using insert command. The query is as follows −
mysql> insert into ComparingDate values('John','2014-04-06 22:50:45');
Query OK, 1 row affected (0.15 sec)
mysql> insert into ComparingDate values('Bob','2018-12-15 15:07:46');
Query OK, 1 row affected (0.14 sec)
mysql> insert into ComparingDate values('Carol','2016-03-10 21:50:40');
Query OK, 1 row affected (0.18 sec)
mysql> insert into ComparingDate values('David','1995-08-08 23:40:47');
Query OK, 1 row affected (0.14 sec)Display all records from table using select statement. The query is as follows −
mysql> select *from ComparingDate;
The following is the output −
+-------+---------------------+ | Name | Login | +-------+---------------------+ | John | 2014-04-06 22:50:45 | | Bob | 2018-12-15 15:07:46 | | Carol | 2016-03-10 21:50:40 | | David | 1995-08-08 23:40:47 | +-------+---------------------+ 4 rows in set (0.00 sec)
Here is the query to compare only date, not time −
mysql> select *from ComparingDate where date(Login) = '2016-03-10';
The following is the output −
+-------+---------------------+ | Name | Login | +-------+---------------------+ | Carol | 2016-03-10 21:50:40 | +-------+---------------------+ 1 row in set (0.00 sec)
