Hi
1 - I have a column whose datatype is longtext. Its content is 08/06/2003;
I created a new column whose datatype is DATE. Its content is null now.
How do write a SQL statement that
inputs each row from 08/06/2003 in the
old column to 2003-08-06 in a new column ?

Eg:
old column name - my_date
new column name - my_new_date

I tried
 select CONCAT(SUBSTRING(MY_DATE FROM 7),
'-',SUBSTRING_INDEX(MY_DATE,'/',1), '-', MID(MY_DATE,4,2)) from dap_cell;

But how do I put this value into its corresponding row in the new column ?

Any help is appreciated.
