Lets I have a table named myTable in mysql with Three field

1. id int autoincrement
2. product_id varchar(20) not null
3. product_name varchar(200) not null

Now I want to keep data in product_id and product_name without white-space.

  • What did you try yourself? Feb 24 '14 at 10:33

Yes, one way to do this will be to create a insert trigger on the table...can trim the values before inserting into the table ..

  • any specific reason to use trigger ? Feb 24 '14 at 15:07
  • whenever new records are inserted or any existing records are updated in the table ,it will ensure that only valid data (without white-space in your case) is entered into the table Mar 7 '14 at 10:15
