SQL syntax error message is wrong

[strBean]

I'm getting "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1". I have not changed this string since it worked just fine a few minutes ago. I double-checked to make sure I hadn't inadvertently changed it, and double-checked the syntax.

What else can cause this message when you know your SQL syntax is correct?

Try echoing the SQL statement as part of the die(). You'll see what went wrong in the last few minutes...

Gracias, amigo. Ya encontré la variable que era vacía, pero Ud. tiene una buena idea que voy a probar la próxima vez que el problema ocurre, antes de que arranque mi cabello.

Asi tiene que ser...
