MySQL STR_TO_DATE() Function

This function in MySQL helps to convert string values to date or time or DateTime values. The function will return zero (0000-00-00) if an empty string is passed as an argument.

Syntax of MySQL STR_TO_DATE() Function

The syntax of MySQL str_to_date() function; as follows:

STR_TO_DATE(str,format)

Here, str (the first parameter) is the string in which there are date parts, and the format (second parameter) format is the string part (determines how string argument is formatted).

Example 1 – MySQL STR_TO_DATE() Function

Let’s take a first basic example of str_to_date() function; as follows:

SELECT STR_TO_DATE('10,12,2019','%d,%m,%Y');

Output-1

+--------------------------------------+
| STR_TO_DATE('10,12,2019','%d,%m,%Y') |
+--------------------------------------+
| 2019-07-20                           |
+--------------------------------------+

Example 2 – MySQL STR_TO_DATE() Function

Let’s take the second example of this str_to_date() function; as follows:

SELECT STR_TO_DATE('15,12,2019','%m,%d,%Y'); 

Output-2

+--------------------------------------+
| STR_TO_DATE('15,12,2019','%m,%d,%Y') |
+--------------------------------------+
| NULL                                 |
