    11 characters in VARCHAR2(CHAR 10)

    I have a database (9.2.0.6) with an account number field specified as VARCHAR2(CHAR10).

    I look in the table and I see 11 digit account numbers. How is that possible? Am I missing something?

    Can you DESCribe the table for us, and then SELECT a column that illustrates this?

    Thanks

    You mean VARCHAR2(10 CHAR) ?

    Maybe, you cant count or the stored values use characters from fonts that look like double numbers, because 10 char is 10 characters, regardless of the unicode bytes needed to make that charactere

    It seems that in 10.2.0.3 when direct=true it lets in the 11 characters. We tested and were able to reporoduce the issue

    Publish your case so others can replicate it.
