Getting a SQL Express Database to work on a SQL Server

Hi,

I'm getting ready to deploy an ASP.NET application to a server that does not support SQL Express, but does support MS Access and SQL Server. Is there any easy way to convert my SQL Express code to either Access or regular SQL Server code, without having to change very much code in my application. I really like the integration that SQL Express has with Visual Web Developer, and would like to be able to keep that sort of integration if at all possible.

Thanks,
Drew

Assuming by "SQL Server" you mean "SQL Server 2005", the only thing that should need to change is the connection string. The rest of your code should be able to remain the same.|||

Try this blog and if it works let me know

Getting a 404/401 on a long running report

Greetings.
I have a report that I am running through ASP.Net with the rs.render method.
When I have a longer date range, the execution time of the query gets longer
and I start to get funky errors. Namely, at around 3 minutes, I get
prompted for network credentials by the standard IE prompt. It doesn't
accept what they are, and after a few times, it takes me to a 404 saying that
the page can't be found. If I try to cancel the prompt, I get a 401 that I
don't have access. I'm not sure what else to look at here. This report has
worked fine in the past, and there are no problems if I just scale back the
date range.
I have the render make a pdf file in a virtual directory on my web server
and then my postback page has a client script inserted to open a window
showing that pdf file.
Anyone have any ideas?
Dale.I fixed it.
It turns out that the HTTP connection timeout settings needed to be
increased a little bit to allow the report to complete. The default of 120
seconds had worked fine in IIS 5 on Windows 2000 Server, but the same value
in IIS 6 on Windows 2003 Server didn't fare too well.
Also, I wound up re-writing the stored proc for the report. The original
author of it had cursors and correlated subqueries doing things they were
never intended to do. Execution time is now 33s instead of 10m15s.

GETDATE() to insert into a datetime field

Hi there, may seem like a really silly question, but i am new to SQL.
I'm building as ASP application in Dreamweaver MX2004 i'm using the insert
record behaviour to upload information to the SQL Server. one of the fields
is DateRegisterred which in Dreamweaver is a hiddenfield with the value set
to GETDATE() called datereg so on the upload behaviour Dreamweaver should
upload GETDATE() from datereg to thedatetimefield DateRegisterred on the SQL
server. However on trying this i get the following error message -
Error Type:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E07)
[Microsoft][ODBC SQL Server Driver][SQL Server]Syntax error converting
datetime from character string.
/driverjobs/candregistration.asp, line 161
Please any advise as how to fix this would be really really appreciated.
Many thanks
GarethHi
It looks like your field is being taken as a string and you have issues with
the format of the date. Try using using CONVERT(char(19),GETDATE(),120)
instead of getdate() on it's own. If you want to truncate the time use
CONVERT(char(8),GETDATE(),112)

You can't put SQL into your code like that, it should be in the query that
you call and then populate the field from this value (in the same way you
populate others!). If you can use the datetime that the insert is made,
then it can be missed out completely and the column defined as not nullable
with GETDATE() as the default.

only leaves me with one problem.
On another page users are allowed to post information for a period of time
which they chose from a drop down list -
where the item label is forinstance 7 days & the value is
DATEADD(d,7,GETDATE())
They can chose from 7,14,21 or 28 days - their choice populates a field
called expirydate.
My theory apparently wont work now, any ideas as to how i can get around
this one?
Onced again thanks for your help

This may help with the previous issue http://www.aspfaq.com/show.asp?id=2347
Instead of giving a offset, you may want to use a date picker see
http://www.aspfaq.com/show.asp?id=2309, if you do go with the original
option then if you are building up a string for your update statement you
can do something like (untested!):
<%
SQL = "UPDATE table SET NextDate = DATEADD(dd," &
Request.Form("DateOffset") & ",GETDATE())"
response.write sql
%>
If you are calling a stored procedure then you just need to pass the
offset value.

If you mean the default for column, then you don't need dateadd e.g
CREATE TABLE MyDates ( id int, dateval datetime not null default
convert(char(8),getdate(),112))
INSERT INTO MyDates (id, dateval ) VALUES ( 1,GETDATE())
INSERT INTO MyDates (id) VALUES ( 2)
INSERT INTO MyDates (id, dateval) VALUES ( 3, '20051225' )
INSERT INTO MyDates (id, dateval) VALUES ( 4, '20051224 23:59:59' )
SELECT * FROM MyDates

get the description of a column

Okay guys heres the senario.

I have written a kick butt asp application that allows me to test sql
statements and manage/display all my databases from the web but I have
a feature I want to include that I can't figure out how. In Enterprise
Manager, one of the column editable properties is the Column
Description. I can't find it in sql server itself. only in the
Enterprise Manager. I need to access it using a sql statement so that
it will display in my table definiation view that I create in the asp
app.These descriptions are kept as extended properties in sysproperties.
Look up sp_addextendedproperty in the help file for more information.
To figure out what Enterprise Manager is doing in situations like
these, you can use Profiler to see what SQL code it is sending to the
server.
