Mysql Search + Replace
// Performing a search-and-replace through a table is easy with MySQL when you know how.
// http://blog.urbanmainframe.com/2008/07/mysql-search-replace/
update table_name set table_field = replace(table_field,'replace_that','with_this');
So, for example, let’s say you have a table called “posts†with a data stored in a field called “content†and you want to replace all instances of the word “dog†with “catâ€, then your SQL would look like this:
update posts set content = replace(content,'dog','cat');
