ORA-00911: invalid character

Currently, I do my project using .Framework, C# language program and oracle 10 g database. It suck things to configure it Windows Operating System 64 bit. Forget about it. It is about ORA-00911: invalid character.

If you find ORA-00911: invalid character, it is because “;” at the end of query. Just remove it. The problem solved. This is a stupid mistake, but can make headache.
