Hi,
Is there a reason why sometimes some of the link options in Crystal Reports are disabled?
eg the FULL OUTER JOIN.
I can't think of a reason why a full outer join wouldn't work?
Hope somebody can help me.
tnx!
No hurries, no worries.

Hi,
I found that there are two practices for writing queries for adapter.
1. one adapter queries for one table in the database
e.g. select * from customer
2. one adapter queries for joinned table in the database
e.g. select * from customer c1, country c2 where c1.country = c2.country
Are the update/insert/delete command of an adapter work only for one table only?
Which practice is encouraged?
If the two tables are filled into the dataset, are there any SQL queries method to do the "join" operation to the two tables? anymore operations can be done?
Thanks

Personally, I would never rely on the auto generated code for the INSERT/UPDATE/DELETE commands in an Adapter - because it cannot assume anything about the database it creates some awful SQL to ensure that it works.

I would encourage you not to use any Wizard generated adapters. Also, never do a SELECT * if the underlying table changes then the results back to your application may be different and your application may not expect that.

Is there a way to package and deploy only the engine and any runtime support for a SQL Server database?
If not and I have to tell the user that SQL Server is required, what is the easiest way to install my application's schema and data into an existing SQL Server database? In previous situations, I've exported the data and used the bcp command-line app to import the data. Is that the best way or is there an alternative?

I have a DataTable (a table in ASP.NET) in memory which I need to pass into an SQL stored procedure.
How can I achieve this? Is there any to pass the contents of the table into my stored procedure given that the size (number of rows) of the table is unknown?

Convert it to an XML document and use OpenXML in your stored procedure to turn it into a table.

Thanks for the response.
At the moment, I've just done it as a string with delimiters (commas and full-stops). Is there any disadvantages of doing it this way? Are there any advantages of using an XML document?
|
|

The advantages are just that the documents form is in a sensible format, that is to say, the XML parser is able to tell what's data and what's metadata. If you pass in a comma or full stop in your data, you could have problems.

Did you forget to check 'Do not treat <'s as HTML tags' ???
Either way, it seems your config file is wrong. Start with a hard coded connection string, then when that works, read up on how to add stuff to your config file in MSDN, and do that seperately. Then you can solve one problem at a time.

Have this at the top of your page
<%@ import Namespace="System.Data.SqlClient" %>
<%@ import Namespace="System.Data" %>
Then either in your script block or your code-behind, use something along the lines of:
Dim objConn As New SqlClient.SqlConnection
objConn.ConnectionString = "data source=SERVERNAME;initial catalog=DATABASENAME;uid=USERNAME;pwd=PASSWORD"
objConn.Open()
