11g ORA-00911 and ASCII Character 255
I have a somewhat simple SQL statement that has been running well for years in 8i and 10g. I ran it in 11g2 and had an ORA-00911 - invalid character - error returned. I copied the statement from TOAD to MS Word and noticed some little circles instead of spaces. These little circles are ASCII 255 characters instead of ASCII 32 spaces. After replacing the ASCII 255 characters with ASCII 32's, it runs properly in 10g and 11g.
It seemed to run correctly in SQL Plus but that might just be due to cleanup when copying and pasting. I noticed that when I copied the statement from Word back to TOAD, the ASCII 255's were replaced by 32s.
