How many processors will MSDE support? |
| |
MSDE supports up to 2 processors on an NT box, and it
supports 1 processor on a Win 9x box. |
|
|
Is there a license limit on the number of concurrent
MSDE users? |
| |
There is no limitation (via licensing or otherwise) on
the number of users that connect to MSDE. However, Microsoft asserts
it is "tuned" for 5-6 concurrent connections. Within
the context of Access projects, a connection equals a session.
Generally, each user will have just one session, but there is nothing
to stop an individual from opening concurrent, multiple sessions.
Anecdotal information suggests that MSDE can support many more than 5
concurrent connections for some applications. Sign the Guest
Register and tell your story about MSDE capacity in the comments

How do I find out the names of the diagrams in my SQL
Server or MSDE database? |
| |
Run this query to generate a list of the diagram names
in a database:
SELECT *
FROM dtproperties
WHERE (property = 'DtgSchemaNAME')

How do I copy a database from one SQL Server to
another (including an MSDE server)? |
| |
There are at least a couple of ways to tackle this
problem programmatically. First, you can use Transact-SQL in a
stored procedure. Second, you can use SQL-DMO objects in a VBA
procedure. You can find out about either through the SQL Server
Books Online resource.
No matter which of the above two approaches, you will want to learn
about the following system stored procedures: sp_detach_db,
sp_attach_db, and sp_attach_single_file_db.

|
How do I manually copy a database from one SQL Server
to another (including an MSDE server)? |
| |
The way that I like the most uses the Data Link
Properties dialog that you can open with the File > Connections
command. Copy your database and log files to disk. If you
control the server, shut it down to do this manually and then re-start
your server. Otherwise, you have to use something like the file
system object. When you get to the MSDE computer (maybe it is at
home), copy the database and log files to your MSDE server. Open
an .adp file and connect it to the copied files using the Data Link
Properties dialog. Select the radio button for attaching a
database file and browse to the .mdf file for your copied database. |

I cannot get milliseconds to appear for datetime
values in stored procedures that I display from the Access 2000 stored
procedure template? How can I include milliseconds in my results
from Access 2000. |
| |
The inability of Access 2000 to return milliseconds from
stored procedures that run in the Access stored procedure template is
a bug. For example, milliseconds do appear when appropriate from
stored procedures that you run from Query Analyzer. One
work-around to the problem is to capture milliseconds along with other
time units with the DATEPART function. Then, compose your own
string representation for time. |

How can I obtain the developer edition of SQL Server
7.0 for FREE? |
| |
If you have a license for Microsoft Office 2000
Developer Edition, you may not know that you can obtain a copy of the
SQL Server 7.0 developer edition with the Access Worflow Designer (AWD).
You can learn more about the AWD and how to get your copy of the
developer version of SQL Server 7.0 by clicking here. |

|
What's a system stored procedure? |
| |
This is a built-in Transact-SQL program that typically
performs some administrative task with SQL Server and MSDE. The
preceding answer references three system stored procedures.
There are literally scores of other system stored procedures.
System stored procedures start with an sp_ or an xp_ prefix. You
invoke them from an Access project stored procedure template by
replacing text after the As keyword with EXEC followed by the name of
the system stored procedure and any relevant arguments. For
example, EXEC sp_columns Customers can provide meta about the columns
in the NorthwindCS database. |
|
|
Will NorthwindCS install automatically if I already
installed MSDE? |
| |
The NorthwindCS front-end is copied to your machine when
you choose to install the Access samples. This process is totally
independent of MSDE being on the box or not.
If MSDE is running on your machine when you open the NorthwindCS ADP
for the first time, you are given the opportunity to install the
back-end database. If you choose to install it, scripts that generate
the database, tables and data run. If you are not running MSDE, you
are prompted for the location of a SQL Server so that the database can
be created there. |
|
|
Do I have to use CREATE PROCEDURE to create a
new stored procedure? |
| |
No. You can use the Alter Procedure statement
inside of an Access project. |
|
|
When I perform division between two integer
quantities with SQL Server, the result is an integer quantity that
truncates the fractional values in the quotient. This does not
happen with Access. How do I get the fractional part of a
quotient when dividing one integer into another in SQL Server? |
| |
Apply a Cast function to the numerator and denominator
that transforms each from an integer quantity to a floating quantity.
For example, your SELECT statement can have an expression like this
CAST(SUM(quantity) AS FLOAT)/CAST(COUNT(quantity) AS FLOAT). |
|
|
I have used the ADP data wizard many times, but I
always had my computer connected. Recently, I tried to create a
database without having my computer connected. The wizard failed
with a message about network connectivity. Is the database
wizard for adp files with MSDE not to work unless you are connected? |
| |
When using the database wizard to create a new .ADP file
(whether to an existing or a new database), you must have a valid
network connection to either a SQL Server backend or the SQLServer
service (MSDE or SQL Server 7.0) on your local machine. |
|
|
A Win 9x machine in my office fails to enable MSDE as
a server on a local network, but MSDE acts as a server from other
computers in the office network. The computer that does not
expose MSDE as a server performs file sharing with the rest of the
network. What could cause this? |
| |
One cause of this problem can be the Browse Master
setting for File and printer sharing on Microsoft networks.
Right click your Network Neighborhood icon and choose Properties.
Then, select File and printer sharing on Microsoft networks and click
Properties to open a dialog containing the property setting. The
default setting is Automatic, but it should be Enabled for this and
selected other functions. |

I'm developing an application with SQL Server as a
back end using triggers. How do I deploy this to my customer
with MSDE? (The customer isn't ready to buy SQL Server.) |
| |
Go to http://msdn.microsoft.com/library/techart/msdedeploy.htm
for a white paper on deploying Access solutions and the Office
2000 Developer Edition re-distributable MSDE via its Package and
Deployment wizard. If you do any work with Visual Studio, you
may also find some value in http://msdn.microsoft.com/vstudio/msde/deploying.asp.
Additionally, Rick Dobson has several articles either out or
forthcoming on developing Access 2000 solutions with SQL Server/MSDE
databases in SQL Server Magazine, Microsoft Office & VBA
Developer, and Visual Basic Programmer's Journal. In addition,
the Programming
Microsoft Access 2000 book has a chapter on the topic. |
|
|
I am not able to install the sample database from
Rick Dobson's MSDE article in the Visual Basic Programmer's Journal? |
| |
Two common factors emerged as reasons for the
installation program associated with the article not working.
First, your VBE project requires a reference to the SQL-DMO object
library. Use the Tools > Reference command to create the
reference. Second, you are running an obsolete version of NT 4.
The sample application requires Service Pack 4 or greater. If
you have an older version, the sample will not work. |
|
|
After having MSDE work for months, I was no longer
able to add tables, or other database objects to Access projects.
What can I do to get my MSDE back? |
| |
Actually, the problem need not be with MSDE at all.
See if you can connect and create tables for the MSDE databases from
another computer with a different copy of Microsoft Office. If
so, your problem may be with Office 2000 instead of MSDE.
If you have already re-installed MSDE and the problem still persist,
this is particularly likely.
Another site visitor reported success with your problem by running
ScanDisk. Select automatically fix errors before starting the
program.
By the way, you should be careful about re-installing MSDE since
the version of the MSDE database engine will not by default know about
your databases from the prior version. If you have a version of
the master database from the former database version, you can try that
to see if it lets you recover your databases from the earlier version.
Otherwise, there are several more involved techniques. One of
these is discussed on pages 480-481 of the Programming Microsoft
Access 2000 book. Go to the About the Book link on the
Home Page for this site to learn more about the book.
