Remove First Part of a Column Value
Let's say you have some values in your MySQL database that look like this:
a_180.0/v1355635866/r0y0ajbjiqry42tqscof.jpg
You want to to remove the first bit in a bulk process (the a_180.0/) and you don't want to have to write a 10 line Python script. Well then, do it in good 'ol SQL.
Table: event_photo, Column: original_image_id
UPDATE event_photo SET original_image_id = TRIM(LEADING 'a_180.0/' FROM original_image_id);
If you want to remove the .jpg part of the column value you can do this:
UPDATE event_photo SET original_image_id = TRIM(TRAILING '.jpg' FROM original_image_id);
If you have spaces in the front or back of the value and you want to remove those just do this:
UPDATE event_photo SET original_image_id = TRIM(original_image_id);
