Extract Numeric Date Value from Date Format in MySQL?

For this, use UNIX_TIMESTAMP(). Following is the syntax −

select UNIX_TIMESTAMP(STR_TO_DATE(yourColumnName, "%d-%b-%y")) as anyAliasName from yourTableName;

Let us create a table −

mysql> create table demo34 −> ( −> datevalue varchar(40) −> ); Query OK, 0 rows affected (1.51 sec)

Insert some records into the table with the help of insert command −

mysql> insert into demo34 values('31−Jan−19'); Query OK, 1 row affected (0.13 sec) mysql> insert into demo34 values('03−Mar−21'); Query OK, 1 row affected (0.12 sec) mysql> insert into demo34 values('13−Jun−20'); Query OK, 1 row affected (0.11 sec)

Display records from the table using select statement −

mysql> select *from demo34;

This will produce the following output −

+-----------+ | datevalue | +-----------+ | 31−Jan−19 | | 03−Mar−21 | | 13−Jun−20 | +-----------+ 3 rows in set (0.00 sec)

Following is the query to extract numeric date value from date format −

mysql> select UNIX_TIMESTAMP(STR_TO_DATE( datevalue, "%d-%b-%y")) as Numeric_Date from demo34;

This will produce the following output −

+--------------+ | Numeric_Date | +--------------+ | 1548873000 | | 1614709800 | | 1591986600 | +--------------+ 3 rows in set (0.00 sec)
