A component that I'm using expects the tables within it to be accessed as
properties (DataSetName.Ta bleName). I have created a DataSet like this:
dsTaskActivitie s = new DataSet();
odbcDA_TaskActi vities.FillSche ma(dsTaskActivi ties, SchemaType.Sour ce,
"Tasks");
My DataAdabpter contains the necessary SQL to retrieve the table, "Tasks",
and the new table ends up in the Tables property of the DataSet but not as
an individual property of the DataSet.
Can anyone tell me how to create the DataTable such that it becomes a
property of the DataSet?

you have to create the property yourself,
write a class MyDataSet e.g. that inherits from DataSet and just add the
property
e.g.
public DataTable Tasks
{
get { return this.Tables["Tasks"]; }
}

Thanks for writing back.
This didn't work for me. But what I found did work was this:
I used the IDE to create a new DataSet with a DataAdapter. I then renamed
the default table "Table" to "Tasks" by editing the xsd definition of the
table schema using the DataSet's local menu choice "View Schema...".
I'm wondering if there isn't some way to rename the table within the
"DataSet Properties..." dialog. It seems like there ought to be.

Christopher,
All you need to do it to create a typed dataset. This way all of the
code will be autogenerated for you, and not only for the table, but
also nested classes for the table itself and for the table's rows. The
row class, in turn, will expose properties and methods for each of the
columns.
There are 2 similar ways of doing so:
1) Simply create a new dataset, open it in Design mode, and then drag
a table (or as many tables as you want) from the Server Explorer tab
in IDE. You must have a link to the database in the Server Explorer.
2) Design your dataset yourself, by adding elements, attributes of
proper types and relations in the designer.
If you do like shown above, you shouldn't be messinng with XSD
directly. Also do not touch the code behind, because it's re-generated
every time you touch the Designer or XSD.
Typed datasets are very poverful and encapsulate you database tables
and views schema almost completely, down to every column and its
properties.

I'm having a problem with a table that accidently had a column added
whose type is the same as the table. This is seriously creating a

get rid of this. Does anyone know of a way to get the database to
allow a drop of a table that has this sort of situation.
Here's a sample of what I get...

Hi,
I get a DataTable based on this simple query:
SELECT * FROM Customers
Later, I want to know just the table name because I do not want to play with
the string within the SELECT statement. I expect DataTable.TableName to give
me an exact name, i.e. "Customers", but it gives me "Table" regardless of
what query from what table. Can someone gives me some clarifications on the
TabeName property? Thanks in advance.

The PL/PGSQL documentation contains at least two examples of functions
which take an argument of type "tablename", which then serves as a
table name in a query. Here's one of those examples:

> DECLARE
> in_t ALIAS FOR $1;

Hello,
Under mysql, we have "desc tablename" to get the detail information
about a table. My question is about to get column name, and column type
for a specific table under PostgreSQL through JDBC.
Assume we have a table named "test". Under PSQL, we can input "\d test"
to see the details about table "test" successufully. However, my main
purpose is trying to get column name, column name of a table through JDBC.
