Subject [jira] [Created] (DERBY-6608) Confusing language in BLOB/CLOB Reference Manual topics
Date Wed, 11 Jun 2014 15:14:01 GMT
Kim Haase created DERBY-6608:
--------------------------------

             Summary: Confusing language in BLOB/CLOB Reference Manual topics
                 Key: DERBY-6608
                 URL: https://issues.apache.org/jira/browse/DERBY-6608
             Project: Derby
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 10.10.2.0
            Reporter: Kim Haase
            Priority: Minor


The BLOB topic, http://db.apache.org/derby/docs/10.10/ref/rrefblob.html, has a paragraph followed
by a note stating the following: 

{blockquote}
The length is given in bytes for BLOB unless one of the suffixes K, M, or G is given, relating
to the multiples of 1024, 1024*1024, 1024*1024*1024 respectively.

Note: Length is specified in bytes for BLOB.
{blockquote}

Why the note is necessary is not clear to me. Wouldn't it make sense to remove it and rewrite
the paragraph to say,

{blockquote}
The length is specified in bytes for BLOB unless one of the suffixes K, M, or G is given,
relating to the multiples of 1024, 1024*1024, 1024*1024*1024 respectively. If a suffix is
specified, the length is in kilobytes, megabytes, or gigabytes.
{blockquote}

The CLOB topic, http://db.apache.org/derby/docs/10.10/ref/rrefclob.html, is even more confusing:

{blockquote}
The length is given in number characters for both CLOB, unless one of the suffixes K, M, or
G is given, relating to the multiples of 1024, 1024*1024, 1024*1024*1024 respectively.

Length is specified in characters (unicode) for CLOB. 
{blockquote}

Would it be correct to say the following?

{blockquote}
The length is specified in numeric Unicode characters for CLOB unless one of the suffixes
K, M, or G is given, relating to the multiples of 1024, 1024*1024, 1024*1024*1024 respectively.
{blockquote}

I'm not sure how to express what the 1024 multiples are, though. Maybe it's not necessary
to do so.
