I need a sql query that will search and replace the following string of text inside a field in my database table.  I want to replace the string ' with the single quote character.  Right now, I have a bunch of LastName fields that look like this:

D'Antonio
O'Block
O'Brien
O'Donnell
O'Flaherty

Again, I just want to get rid of that HTML equivalent and use the literal single quote character instead.

TIA for assistance in constructing this query!

If REPLACE is still a valid function in MSSQL 2005 then this should work.  Backup your table first or try in test!

update tblName
   set lastName = Replace(lastName, "&#39", "'")
 where lastName like '%#39#%';

Had to give full points to this solution since A) it came in first, B) was the full working solution and C) the other solution did not work due to double quotes being used and not single quotes in the replace statement.  Thanks for expert assistance!
