Comparison of varchar date records from the current date in MySQL
For date comparison, you can use STR_TO_DATE(). Following is the syntax −
select * from yourTableName where str_to_date(yourColumnName,'yourFormatSpecifier') > curdate();
Let us first create a −
mysql> create table DemoTable1397 -> ( -> AdmissionDate varchar(40) -> );s Query OK, 0 rows affected (0.97 sec)
Insert some records in the table using insert −
mysql> insert into DemoTable1397 values('01/04/2019'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1397 values('27/09/2019'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1397 values('29/09/2018'); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1397 values('29/09/2019'); Query OK, 1 row affected (0.08 sec)
Display all records from the table using select −
mysql> select * from DemoTable1397;
This will produce the following output −
+---------------+ | AdmissionDate | +---------------+ | 01/04/2019 | | 27/09/2019 | | 29/09/2018 | | 29/09/2019 | +---------------+ 4 rows in set (0.00 sec)
Let us first find the current date −
mysql> select curdate(); +------------+ | curdate() | +------------+ | 2019-09-27 | +------------+ 1 row in set (0.00 sec)
Following is the query to compare varchar date with the current date in MySQL −
mysql> select * from DemoTable1397 -> where str_to_date(AdmissionDate,'%d/%m/%Y') > curdate();
This will produce the following output −
+---------------+ | AdmissionDate | +---------------+ | 29/09/2019 | +---------------+ 1 row in set (0.07 sec)
