Hello, very useful as you mention, what I want to do is look inside
post a specific keyword and replace it with a link to a web
position, taking into account that the Keyword may already be inthe wrong.
ideas perhaps with a cursor?

Thanks, this was much quicker than doing the tiresome Search and Replace method… And, it also made me realize I really should buff up on my SQL skills
hi, thanks for this useful post, i already move my blog to another domain and realize that all images on my post still pointing to old domain, so i need to find and replace all url on my post with my new domain. Thanks.

@Jamie: That can quickly become very time consuming; especially with a WP installation that has pre-existing content and permalinks.

Another option is to do an export from MyAdminSQL and then do a find and replace on the text export, rename the table as backup and import the text file

Jed,

You’re right, I knocked my head against the wall for a couple of hours trying to figure out what the heck was going on. Phpmyadmin put those “ticks” in place of single quotes after a failed query took me back to the query screen with my previous attempt slightly modified. After figuring this out everything worked as advertised and I was able to find and replace all those urls referring to the old website with ones for the new.

One note: I was not able to escape the forward slashes. In MySQL 5.x escaping anything other than a small predetermind set of characters (I’d have to go back to look) apparently has no effect. SO I focused on just the actual URL part without the “http://” and that worked just as well.

Two references to this behavior:

I may be missing something.

Thanks for responding.

Hi Jesse,

It looks like you might have had some improper characters in your statement, maybe some “smart” or “curly” quotes snuck into our syntax. Try again using the above example.

This doesn’t work for me under My SQL 5.0x. I still get an error that doesn’t recognize the backslashes.

Error
There seems to be an error in your SQL query. The MySQL server error output below, if there is any, may also help you in diagnosing the problem

ERROR: Unknown Punctuation String @ 63
STR: :\/\/
SQL: update wp_posts set post_content = replace(post_content, ‘http:\/\/keyissues.mu.nu\/archives\/’, ‘http:\/\/www.keymonroe.com\/wp-content\/uploads\/’)

SQL query:

update wp_posts set post_content = replace(post_content, ‘http:\/\/keyissues.mu.nu\/archives\/’, ‘http:\/\/www.keymonroe.com\/wp-content\/uploads\/’)
