It it possible to apply this to an entire column inside a table? In a table, I have a column with a string inside it, and I need to capitalize the first letter of every word.

Is this possible using your function?

Thanks,

For you guys that are getting the mysql error…

The default delimiter in mysql is shown at the bottom of the sql query window as a semi-colon. You have to change that. Make it a tilde and the script will work perfectly.

– Nice effort though.

I hope you don’t mind if I publish this on my blog too? I will link back to you, of course…
