Multi-user Access Through A Data-access Layer/remoting Server
Oct 30, 2007Hi guys,
I've been developing desktop client-server and web apps and have used Access and SQL Server Standard most of the time.
I'm looking into using SQL CE, and had a few questions that I can't seem to get a clear picture on:
- The documentation for CE says that it supports 256 simultaneous connections and offers the Isolation levels, Transactions, Locking, etc with a 4GB DB. But most people say that CE is strictly a single-user DB and should not be used as a DB Server.
Could CE be extended for use as a multi-user DB Server by creating a custom server such as a .NET Remoting Server hosted through a Windows Service (or any other custom host) on a machine whereby the CE DB would run in-process with this server on the machine which would then be accessed by multiple users from multiple machines??
Clients PCs -> Server PC hosting Remoting Service -> ADO.NET -> SQL CE
- and further more can we use Enterprise Services (Serviced Components) to connect to SQL CE and further extend this model to offer a pure high-quality DB Server?
Clients PCs -> Server PC hosting Remoting Service -> Enterprise Services -> ADO.NET -> SQL CE
Seems quite doable to me, but I may be wrong..please let me know either ways
Thanks,
CP
Data Access Layer Advice
Jun 19, 2007I've been following Soctt Mitchell's tutorials on Data Access and in Tutorial 1 (Step 5) he suggests using SQL Subqueries in TableAdapters in order to pick up extra information for display using a datasource.
I have two tables for a gallery system I'm building. One called Photographs and one called MS_Photographs which has extra information about certain images. When reading the MS_Photograph data I also want to include a couple of fields from the related Photographs table. Rather than creating a table adapter just to pull this data I wanted to use the existing MS_Photographs adapter with a query such as...1 SELECT CAR_MAKE, CAR_MODEL,
2 (SELECT DATE_TAKEN
3 FROM PHOTOGRAPHS
4 WHERE (PHOTOGRAPH_ID = MS_PHOTOGRAPHS.PHOTOGRAPH_ID)) AS DATE_TAKEN,
5 (SELECT FORMAT
6 FROM PHOTOGRAPHS
7 WHERE (PHOTOGRAPH_ID = MS_PHOTOGRAPHS.PHOTOGRAPH_ID)) AS FORMAT,
8 (SELECT REFERENCE
9 FROM PHOTOGRAPHS
10 WHERE (PHOTOGRAPH_ID = MS_PHOTOGRAPHS.PHOTOGRAPH_ID)) AS REFERENCE,
11 DRIVER1, TEAM, GALLERY_ID, PHOTOGRAPH_ID
12 FROM MS_PHOTOGRAPHS
13 WHERE (GALLERY_ID = @GalleryID)
This works but I wanted to know if there's a way to get all of the fields using one subquery instead of three? I did try it but it gave me errors for everything I could think of.Is using a subquery like above the best way when you want this many fields from a secondary table or should I be using another approach. I'm using classes for the BLL as well and wondered if there's a way to do it at this stage instead?

Having Trouble Following Tutorial - Working With Data In ASP.NET 2.0 :: Creating A Data Access Layer

Deleting Using SqlDataAdapter Via A Data Access Layer
Feb 20, 2008I've a management module (managing Products) currently being displayed on the aspx page using ObjectDataSource and GridView control.The datasource is taken from a class residing in my Data Access layer with custom methods such as getProducts() and deleteProduct(int productID)I'm currently using SqlDataAdapter as well as Datasets to manipulate the data and have no big problems so far.However, my issue is this, each time i delete a product using the deleteProduct method, I would need to refill the dataset to fill the dataset before i can proceed to delete the product. But since I already filled the dataset using the getProducts() method, is it possible to just use that dataset again so that I dont have to make it refill again? I need to know this cos my data might be alot in the future and refilling the dataset might slow down the performance. 1 public int deleteCompany(Object companyId)
2 {
3 SqlCommand deleteCommand = new SqlCommand("DELETE FROM pg_Company WHERE CompanyId = @companyId", getSqlConnection());
4
5 SqlParameter p1 = new SqlParameter("@companyId", SqlDbType.UniqueIdentifier);

7 p1.Direction = ParameterDirection.Input;

9 deleteCommand.Parameters.Add(p1);
10 dataAdapter.DeleteCommand = deleteCommand;
11
12 companyDS = getCompanies(); // <--- I need to refill this before I can delete, I would be iterating an empty ds.

14 try
15 {
16 foreach (DataRow row in companyDS.Tables["pg_Company"].Select(@"companyId = '" + companyId + "'"))

Error Trying To Add Information To DateTime Field Using Data Access Layer
Sep 20, 2006I am taking my first stab at a 3 tier architecture within ASP.Net. I have been adding datasets and creating a new Insert to add certain parts to a table. I am trying to add a date field called 'DateAdded' and is setup in SQL as a DateTime. When Visual Studio auto created the dataset, the Insert function is not "DateAdded as Datetime" as I would have expected, but it is "DateAdded as System.Nullable(Of Date)". There is a space in between 'Of' and 'Date'. If I keep the space in there the insert function shows an error that says "Arguement not specified for parameter DateAdded of funtion( etc. etc.). If I take the space out, the error on the insert function goes away but there is an error within the "OfDate" that says "Array bound cannot appear in type specifiers". I am confused on why the date format changed and how I can get a date to go into the database using the autogenerated datasets from Visual Studio. Any help would be appreciated. Thanks, Mike
View 1 Replies View RelatedError Using SQL Datatype Text As Output Parameter From C# Data Access Layer
May 19, 2008
Hello,
My datalayer of C# code is invoking a stored procedure that returns a varchar(max) SQL data type. In my ASP.NET code, I have:
SqlCommand myCommand = new SqlCommand("usp_GetTestString", myConnection);
myCommand.Parameters.Add(new SqlParameter("@TestString", SqlDbType.Text));
myCommand.Parameters["@TestString"].Direction = ParameterDirection.Output;
myConnection.Open();
myCommand.ExecuteNonQuery();
return Convert.ToString(myCommand.Parameters["@TestString"].Value);
The query fails to execute and returns an error: String[1]: the Size property has an invalid size of 0. If I change the SqlDbType.Text parameter type to SqlDBType.Varchar, 100 (or any other fixed varchar length), it works but limits the length my unlimited field text. Any suggestions on how I can use db type text or varchar(max)? The field I need to retrieve is string characters of unlimited length and
hence the datatype varchar(max).

Does MS Access Installation Is Required For Running Application That Uses Access Mdb File
Nov 28, 2006Hi,
I am developing an application that uses Access database (mdb file) to store the user data. The user of this application is not interested in the database file (to view in MS Access Environment). Does the user machine requires MS Access installation to run my application or just some couple of dlls (OleDB driver, Access DB Engine,..) should be enough to run my application?

If I paste the code DROP

Does it gonna work to present the data in the presentation layer after removing the temp table?
The goal is to retrieve the data from a stored procedure and present it in the software's presentation layer and I still need to remove the temptable after using it because I will use the SP many time in production phase.

Help Required Converting From MS Access SQL To TSQL
May 20, 2008Hello, I am fairly new to SQL Server so I apologise if this is the wrong forum. I have a Sales analysis table in a SQL Server 2000 database. The table is populated from various sources in our ERP system. via a DTS package For our French branch sales unit of measure is eachs (EA) for actuals, but the primary UOM and our forecast data is normally in cartons. I have a product master table which defines primary unit of measure, and a unit of measure conversion table. So if I wanted to convert the data all to the primary measure I would write the below in Access:
UPDATE (tblSalesReport INNER JOIN tblItemMasterERP ON tblSalesReport.fldProductNo = tblItemMasterERP.fldProductNo) INNER JOIN tblUOMConvertERP ON (tblItemMasterERP.fldShortItemNo = tblUOMConvertERP.fldItemNo) AND (tblItemMasterERP.fldPrimaryUOM = tblUOMConvertERP.fldUOM1) SET tblSalesReport.fldUOM = [tblItemMasterERP]![fldPrimaryUOM], tblSalesReport.fldQuantity = [tblSalesReport]![fldQuantity]/[tblUOMConvertERP]![fldConvFactor]
WHERE (((tblSalesReport.fldCompany)="00007") AND ((tblUOMConvertERP.fldUOM2)=[tblSalesReport]![fldUOM]) AND (([tblSalesReport]![fldUOM])<>[tblItemMasterERP]![fldPrimaryUOM]));
I have found that in the DTS I can add an SQL task, but it seems to only allow UPDATE if there are no joined tables. I found the same thing in Stored Procedures, the SQL designer would only allow me to use one table. I guess I am looking in the wrong places. Can anyone point me in the right direction to incorporate the above sql (or equivolent) into our DTS package. Unfortunately the company decided to dispense with the services of the person who designed the package.
What Kind Permission Required To Access Sys.sysreferences On SQL 2005?
Jul 20, 2006In SQL 2000, a guest user can access any system tables in a database, but it looks not the same in SQL 2005. What even worse is the SQL security handles it in a confused way. When I sign on as sa and run:
SELECT * FROM sys.sysreferences
Of course I get what I want. While, if I sign on as a user only has guest privilege, I get nothing. Based on my understanding, if one does not have permission to SELECT, he should get rejucted error message. Otherwise, he should get return data. Now, SQL 2005 does not give any.
More interesting thing is when select * from sys.sysobjects, SQL 2005 return data to both sa user and user with guest privilege. Did MS applied different security on different sys.sys.. table? When a select return nothing, how can we know if there is no data at all, or the user does not have sufficient privilege.
Please help me to get out this puzzle.
Thanks.
Sample Data Required
Feb 13, 2007Hello.
Though this is not directly a SQL related question but I could not think of some other forum to post this request. <y apologies if I should have posted elsewhere...
I need some sample data for a departmental store (like WalMart of KMart) which sell a wide variety of things and probably everything under the sun :)
I need data in such a manner that we have 4-5 levels of data hierarchy. For example we can have a data hierarchy like follows:
Classification
Category
Sub Category
Product Group
Item
The above is just an example but I hope that most of you already know what I neeed. An example of data based on the following hierarchy can be as follows (shown in a tabular manner)
Classification | Category | Sub Category | Product Group | Item
---------------------------------------------------------------
Household Items| Electronics| Entertainment| Audio| SONY Room entertainment box, 2 speakers 300 W each, ....
Household Items| Electronics| Entertainment| Audio| Phillips Boom Box, ...specifications....
Household Items| Electronics| Entertainment| Video| SAMSUNG DVD Player model SG-17X5 ...
Household Items| Electronics| Entertainment| T.V | SONG TRINTORN 51" .....

C--65--37--....
now this date column will be only 5 i.e. 1 which user puts + 4 preceding dates from user date (ignoring sequence means if user put 10/06/07 then next will be 09/06/07 but if this wont exists then take 08/06/07 & so on till 4 dates)
the data will be unique means no scrip repeats more than once in a day

Static Data: DB Connection Not Required.
Jan 22, 2007I have a report with this data query:
select ID1 = 6, ID2 = 15, ID3 = 3, ID4 = 3
The data is evidently static here, and hence database access is not required.
Is there a way to omit the connection string in the Datasource, or have a disconnected Datasource that does not connect to any database?
Currently I am setting the connection string arbitrarily, but it would be ideal to omit it altogether.
TIA,
