MySQL find and replace

There are times when you need to bulk update a database. Such as changing all references of domain.com to domain.blog in a table of hundreds of records. Doing this manually would be very tedious a better way is to do a find and replace in MySQL directly.

How this works is you do an update specify the table then set the column to be updated and inside a replace command set the column then what you’re looking for and what to replace it with.

update table set column = replace(column,'find','replace')

A practical example of this is:

update posts set content = replace(content,'daveismyname.com','daveismyname.blog')

For the past 12 years, I’ve been developing applications for the web using mostly PHP. I do this for a living and love what I do as every day there is something new and exciting to learn.

In my spare time, the web development community is a big part of my life. Whether managing online programming groups and blogs or attending a conference, I find keeping involved helps me stay up to date. This is also my chance to give back to the community that helped me get started, a place I am proud to be apart of.

Besides programming I love spending time with friends and family and can often be found together going out catching the latest movie, staying in playing games on the sofa or planning a trip to someplace I’ve never been before.
