    Unhappy Replace Specific Characters in mysql PHP

    Hi all, I am working with a site with an old database having more than 2000 product entries... and most of the products have the article number as ASC-000-000-00

    what i want to do is to replace these article numbers with DSC-000-000-00... I dont want to edit/update every entry for that... what I want is just a simple query or 3-4 PHP statements to accomplish,,, any ideas...

    that's too funny... plz read my question again... i want to replace character(s) in mysql and records are more than 2000 ... so str_replace is useless there

    either write a php script that does the following:
    db query -> for each entry str_replace() -> update db

    or export the db data to a txt file and use the search and replace function of an editor (e.g. Notepad++) and import the data into the db again.

    Maybe utilizing the built in string manipulation functions of the DB rather than some convoluted flat file hack as suggested...

    something like this?
    Code:
    update table_name set field_name = replace(field_name,'find_this','replace_with_that');

    That looks about right. I would test on a sample dataset before throwing production data through it just to be safe though.
