PT,
I discovered that Mysql has a way of doing the same thing. I used the
replace() function in MySQL
$query = "UPDATE tblRentalsImport set listPrice =
replace(listPrice,',','')";
I really want to understand the PHP function for str_replace(), but I'm
going to go back to that when I have more time. This is primarily for a
business solution for myself, and after several hours, I had to move on to
the next task since I found a suitable solution. However, I believe that you
answered the question because I did NOT have the WHERE clause in my update
query. That likely explains my dilemma.
Thanks,
Grant
