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 ?
UPDATE dap_cel SET my_new_date = CONCAT(that-long-expression-above);
Any help is appreciated.
