Hi,
Is it possible to retrieve details about the database, specifically a
list of the tables in the database; and then to retrieve the columns
and their types for the tables?
Is this dependant on the database?
Thanks

Yes.

Yes.
Real databases usually store meta-data (list of tables, list of columns,
list of indexes aso...) in system tables which can be queried in the same
manner as common tables or view. Just read your database handbook...

Hello Chris,
Is it possible to retrieve details about the database, specifically a
list of the tables in the database; and then to retrieve the columns
and their types for the tables?
Is this dependant on the database?
Yes and Yes. However some toolkits like SQLObject
( http://www.sqlobject.org/) and SQLAlchemy ( http://www.sqlalchemy.org/)
can do this work for you (IIRC).

Thanks for the great feedback.
Chris.

If you want to know the names of the fields on a recordset, you can use
cursor.descript ion.
For example, lets say you have a connection to a MySQL database:
con = MySQLdb.connect ('localhost','r oot','','mydb')
cur = con.cursor()
cur.execute('se lect * from customers')
result = cur.fetchall()
fields = [i[0] for i in cur.description]
....
Description gives a list with information about your recordset, being
the first item the name of the field.
Hope this helps...

Greetings,
I've been working on a 3-column layout where the center column is of a
fixed width (230px wide). The center column must always be 230px and
the columns on the right/left (always the same size as eachother) must
always take up the remaining width of the browser.
I have been designing for Firefox and IE and routinely viewing the
results in both.

Back in ADO days, it was fairly easy to get the meta data (tablenames,
columnnames , etc) .. with all that schema stuff.
I have a Access database, that I'd like to get the list of tableNames in it.
How does one get the metadata about a database thru DotNet?
Thanks.

Hi,
I have been using GDI+ and Windows Media SDK to get the metadata
information for image and audio files respectively.
Just incase if someone is not clear as to what I mean by metadata
information, its the information regarding the image or audio files
like., height and width for the image.,. Title, artist, author etc for
the audio files.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
