SQLDMO is the easy way.
Also you can use system tables and system stored procedures: sysobjects, etc.

Hi,
I have a several tables defined by an xsd schema which are also
loaded into an ADO DataSet via DataSet.ReadXMLSchema(...)
(they are of the MS specific dataset schema)
I wish to create matching tables in a SQL Server database programatically
using ADO.NET (something like the complement of DataAdapter.FillSchema(...))
without having to explicitly write SQL statements after traversing the DataTable
objects (e.g. SqlCommand mySqlCommand = new SqlCommand("CREATE TABLE...")).
OR
find a utility which will convert my MS dataset xsd file into a script
which can be used, say by sqlcmd.exe, to create tables on a SQL Server 2005
instance.
Am I being too lazy, or is there an existing solution for this problem?
Thanks,
Eric Smith

Is this anything wrong with this query?
CREATE TABLE [1384/6] (OrderTable int NOT NULL ,OrderNo int NOT NULL,OrderTypeIDn nvarchar(20) NOT NULL,Report nvarchar(254) NOT NULL,Receptionist nvarchar(50) NOT NULL ,Cashier nvarchar(254) NOT NULL,Day nvarchar(15) NOT NULL,TimeInstant nvarchar(15) NOT NULL,Description nvarchar(254) )
I am using this query with OleDb on an access database.

Hi there,
As far as my knowledge goes, I dont think so you can create tables through queries in an access database.However there is an alternate way for this using the ADOX object.I am not aware of what programming language you are working on but I am quite sure if it works with asp it has to work on any microsoft platform (.Net,vb6) .
Dim AccessTable as ADOX.Table
AccessTable.Name = "Table1"
AccessTable.Columns.Append ("Column1", adInteger)
AccessTable.Columns.Append "Column2", adVarWChar, 30
AccessTable.Keys.Append ("PK_Column1", 1, "Column1") 'Add a primary key
Hope this helps

Access doesn't recognise nvarchar data type.
You must replace nvachar data type with text !

[kos nagid],the problem was the day nvarchar(15) which Day is a pre reserved word for access........;P
|
|
|
|
|
First) If in Tools menu > Options > Tables/Queries > Is not checked "SQL Server (ANSI 92) Compatible syntax - This database" (which is IMPLICIT option in Access)
then NVARCHAR is not recognise by Access. Instead you must use Text data type.
Solution: query must be rewrite thus:
CREATE TABLE [1384/6] <br />
(<br />
OrderTable int NOT NULL ,<br />
OrderNo int NOT NULL,<br />
OrderTypeIDn text(20) NOT NULL, <br />
Report text(254) NOT NULL,<br />
Receptionist text(50) NOT NULL ,<br />
Cashier text(254) NOT NULL,<br />
Day text(15) NOT NULL,<br />
TimeInstant text(15) NOT NULL,<br />
Description text(254) <br />
)<br />
Second) If in Tools menu > Options > Tables/Queries > Is checked "SQL Server (ANSI 92) Compatible syntax - This database" then NVARCHAR is now recognise by Access
but the problem is "Day" field name wich is reserved word because is the name of DAY function from SQL Server - DAY(date) return a integer representing number of day (between 1 and 31)
Solution:
<br />
CREATE TABLE [1384/6] <br />
(<br />
OrderTable int NOT NULL ,<br />
OrderNo int NOT NULL,<br />
OrderTypeIDn nvarchar(20) NOT NULL,<br />
Report nvarchar(254) NOT NULL,<br />
Receptionist nvarchar(50) NOT NULL ,<br />
Cashier nvarchar(254) NOT NULL,<br />
DayField nvarchar(15) NOT NULL,<br />
TimeInstant nvarchar(15) NOT NULL,<br />
Description nvarchar(254) <br />
)<br />
Ok ?

don't we have to set a distinct on ticker and name to have them once ?

No, becuase the GROUP BY clause is being used to define the level of aggregation. The query is saying that it wants only one row per ticker & name combination and that aggregation functions will be used on other columns to roll them into one value. In this case the MIN() and MAX() functions are used to create one value from the "close" column based on all the values within each ticker/name combination.
For example.
Lets say that the data is something like this:
Ticker Name Close
PRD Pernod Ricard 9000
PRD Pernod Ricard 9058
PRD Pernod Ricard 8945
PRD Pernod Ricard 8988
SSE Scottish & Southern Elec 978
SSE Scottish & Southern Elec 977
SSE Scottish & Southern Elec 969
SSE Scottish & Southern Elec 975
EZY EasyJet 235
EZY EasyJet 240
EZY EasyJet 233
EZY EasyJet 237
EZY EasyJet 232 Now we apply the SQL statment:
SELECT Ticker, Name, MIN(Close) AS MinClose, MAX(Close) as MaxClose
FROM StockData
GROUP BY Ticker, Name The result will be:
Ticker Name MinClose MaxClose
PRD Pernod Ricard 8945 9058
SSE Scottish & Southern Elec 969 978
EZY EasyJet 233 240 If you attempt to put any other columns in the SELECT you will get an error to say that they must either be used in an aggregate function or in the GROUP BY clause.
Does this help?

Trying (and having trouble understanding) to understand "inverse" ...
Quoting documentation:
"You may map a bidirectional one-to-many association by mapping a one-to-many association to the same table column(s) as a many-to-one association and declaring the many-valued end inverse="true".
...
...
...
<many-to-one name="Parent" column="parent_id" not-null="true"
(We also need to add the Parent property to the Child class.)
Now that the Child entity is managing the state of the link, we tell the collection not to update the link. We use the inverse attribute.
<set name="Children" inverse="true">
<key column="parent_id" />
<one-to-many class="Child" />
</set>
What's meant by "managing the state of the link"???
Reference:
http://nhibernate.sourceforge.net/nh-docs/en/html/single/reference.html#collections
Thanks in advance!

Hi guys,
how can i make my sql database read and store data from Oracle db?
because my system reads data from sql database.. but some data need to be read from oracle and stored in sql database so the system can retrieve them from the sql database..
can anyone help me in this case? i don't know how to connect 2 different databases ...
ASP.NET/VB.NET
Regards,
Nina

You could connect the Oracle db as a linked server and use direct SQL commands between the two servers on the SQL Server side. Look up the books online for linked servers. You will have to configure an ODBC to oracle server from your SQL box.

Can you please write the connection string?? ( one example please..)
