Here's a sample table:
name | picture
John S. | http://servera.host.com/johns.png
Linda B. | http://servera.host.com/lindab.png
...
Let's say there are several hundred more records.
Let's also say we moved servers from "servera" to "serverb".
Would it be possible to go into this table with one query to rename the content in the column "picture" for every record to read the correct server name?
