numerics highlighted and have an underscore in the middle of them in .SQL file


Hi All,

I have recently upgraded from the community version to the Ultimate Edition of IntelliJ.

One annoying thing I have noticed is that in my .sql libraries any SQL with a 6 character numeric has it highlighted (in grey) and has an underscore in the middle of it.

Nothing I can see indicates why this is happening. If I hover over it it shows the original string and if I click on the text it reverts it. If I copy and past it into another program it displays correctly is only a display change.

Sorry no screenshots by company have fairly strict security and will not allow it.


Any idea what this is and how to turn it off globally?
