Description:
In the online documentation @ http://dev.mysql.com/doc/refman/5.0/en/blob.html it mentions that there are four blob data types, and the only difference between them is the maximum lengths and storage requirements.

I was unable to locate the information online that detailed these differences.

How to repeat:
visit http://dev.mysql.com/doc/refman/5.0/en/blob.html and attempt to find information detailing the differences between the four blob datatypes.

Suggested fix:
It would be nice to have the maximum lengths and storage requirements on this page or if not, how about a link to the place in the documentation that has this information.

What about http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html? There is a link to this page on the page you are complaining about.

The maximum values are shown in the table "Storage Requirements for String Types" at http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html, which is linked in the first paragraph.

Thank you for pointing me in the right direction.
I don't know how I missed that link. I suppose it was because it came right after discussing the text data types. I must have thought that the link was referring only to the text data types.

If I had read it carefully though, I would have seen that the text data types "have the same maximum lengths...".

I apologize for the erroneous report.
