Searching/replacing "select" columns within MySQLi server behaviors

I have a membership database that I inherited, and had to teach myself MySQL to get the database online/dynamic for my client. A preexisting column heading was titled "foreign" to indicate foreign members. Not realizing that "foreign" was a protected field within MySQL coding, I built a ton of server behaviors that GET or POST to my tables data that include this foreign field. Now of course, the posting in this particular field is not working (everything else is) and I realize I need to rename that column (to maybe "overseas"), as well as the "select" field in all my server behaviors.

Is there a quick and dirty search-and-replace operation I can do to accomplish this in code view? Or do I have to go into these server behaviors one by one and make the changes? I'm nervous about this because the panels are half-broken, the database connections are not showing, I'm seeing "***No Table Found", etc. I'm afraid to break the whole thing.

Any guidance would be greatly appreciated!
