I've not used Access in about 6 or 7 years so I don't know if it can. I don't think so.
You can still use parameterised queries rather than inject values in to the SQL Command in Access though - that at least improves the security of your database.

Access does support Stored Procedure.
You can also use Transaction when executing your sql statements if you don't want to use Stored Procedure.
And using parameters is a must as a preliminary security precaution.

1. I have a table open in Server Explorer (data view). I execute an update from C# code. How do I refresh the data view without closing and reopening it? Right-click the table in server explorer and refreshing doesn't work, for example.

Friends i like to ask two questions about the upcoming version of SQL Server i.e SQL Server 2005 (also known as Youkon). If anyone knows the answer then please tell me. Questions are as follows:
1_ Whether Youkon will be ORDBMS
2_ What level of support is provided for complex datatypes and custom objects?
If you know the answer of any of the above question then please tell me.

Hi guys,
I have (hopefully) a simple query regrading full-text indexing. If I start a full population and for whatever reason "stop the population build", can I then just start a full population again?
Im not sure if any indexes get blown out of whack or whether I need to recreate the catalog by dropping it and recreating it. Hope to get some advice on this. Thanks in advance!

Why update statement in a Stored Procedure is Slow ?
Kindly help me in this issue.

I don't think simple update will be slow in stored procedure while comparing Queary statement. If you could post the stored procedure code block then we could able to help you out.

My problem is that I don't know how to connect between two databases of MS.Access on two computers.

Hi Guys,
What I have is a system that has a single table in a sql dbase and the entire contents of this table are dumped into a dataset via sqldataadapter.fill.
Changes to this dataset can be sent back to the dbase fine using the sqldataadapter.update method without any problem as well.
Where I am having problems is in the case that a second user adds rows (or alters existing data) in the database, I cannot seem to get this updated data to syncronize with my client's dataset. I am obviously doing something wrong here and I cannot seem to find an example that shows this.
Can anyone please give me an example of how to do this? I have wasted a lot of time on something I am sure is very simple.
Any help is much appreciated.

ADO.NET uses disconnected model. In multi user scenario it is not advisable to keep the data in the client side using DataSet.
You must use update data in the database as and when needed, i.e. on demand.
|
|
|
|

So you are saying that at each syncronization I should do the following?
- Update the dbase with any changes using the update method.
- Empty the dataset
- Re-download the entire table contents using the fill method ot the dataset
This seems like an awful lot of work downloading for no reason (especially when the table has over 7000 lines). Is there no way to update the dataset contents with changes that have been made in the dbase.
The table has an "id" column containing a unique id and a "datemask" column containing a datetime of the rows last update. Can this not be used to determine concurrancy?
|

No I am not saying that you should do the synchronization by calling update method.
What I am trying to say is that DataSets do not fit well in this scenario.
Typically, a screen has a refresh button in this case. And the user presses the button to refresh the data in the data pane which is generally stored in a DataSet.
Consider the case when the table has 700000 lines, then what will happen. DataSets are designed to handle low transactional small data.

ok,
If datasets are not the best method, what storage method would I use?
Probably best if I explain what I am trying to do...
Currently I have a php/javascript contacts management system that runs on my companies intranet that I wrote and it currently has approx 7000 contacts in it. The idea of this system is to be a C# application that does exactly the same as the php version but, faster and easier to use.
Now, a lot of my users are not local to the dbase server so I was trying to do the following:
- Use dataset that syncronizes back to the sql server at regular intervals
- Dump dataset to xml & schema for offline content, which would then load locally...and update from dbase server (To save long load times on startup and allow offline editing)
I am fairly new to ADO.NET so I must admit to not knowing all the options available.

DataSets are very heavy. You chould use instead create your own classes to hold and manipulate the
the data. The data should be fetched from the database(synchronization) on demand.
One question: Why is the client not connecting to the database directly instead on refreshing periodically?
If you want to do this in the database side,
When you select data from table, you put a lock using the below statement:
select * from table holdlock
then other users have to wait for this transaction to be completed for update.
You can even use isolation level 2 (repeatable read) to keep the consistency.

The reason that I am not designing the system with direct dbase access is that the system will need to be used in offline situations where the user does a syncronization and then goes out on site with a laptop.
The user can make changes offline and then, we he/she gets back online, can syncronize.
This was the other reason I was looking at datasets due to their ability to dump to xml and schema (and import from same) which I was using for offline cache.
I may look into have a table on the dbase that records all changes to any other of the dbase tables hence, rows updated since the last update could be downloaded easily. This might be a way to handle it.

Friends,
I want to attach a database to SQL server without using Enterprise Manager or query. I have my database file *.mdf in certain directory of my computer. I want to attach it with my SQL server. Is there any way i can attach using regisrty or any file entry or programatically?

What are you talking about, "attach a Jet database to SQL Server"? What does this mean? What do you want this to do?
SQL Server doesn't really understand Jet databases. You can import the database, but not all the "stored procedures" as Jet understands the concept anyway.
