MySql convert long date format string (e.g. 20th-March-2001) to date YYYY-MM-DD

Adam :

I am trying to convert long date format string (e.g. 1st-June-1999 or 20th-March-2001) to date YYYY-MM-DD using MySql 5.7.

Reading docs tried to use STR_TO_DATE:

select STR_TO_DATE(dob,'%d-%M-YYYY') from table

However, this returns null due to the day suffix (e.g. th).

I could use update query with REPLACE() to remove the suffix and then STR_TO_DATE, but is there a better solution?

%D does what you want:

str_to_date(dob, '%D-%M-%Y')
