Well, yes. The table in question is specified as such:
CREATE TABLE [dbo].[tbl_exam_questions] (
[question_id] [int] IDENTITY (1, 1) NOT NULL ,
[question_text] [char] (400) NOT NULL ,
[correct_answer] [int] NOT NULL
) ON [PRIMARY]
I've also used a strlen to measure the string length on submission to
the db via a form post, and I've done the same on the returned string
(also via a form post).
On submission the test text I entered was 271 chars, after retreiving
the text I only get 255 chars each time.
I'm only using a very simple query (select * from tbl_exam_questions
where question_id=x;) and using the microsoft client tools such as query
analyser and ms sql enterprise manager, both return the full string.
I've attached the two related php files that deal with the process, I
can't see anything too horrible (other than my coding style) :-)
