Questions About Various DB Connection Methods.
Dec 15, 2006
Hello All,
I am looking to get some guidance and feed back from the community as to the prevalence and usage of the following technologies:
ODBC Descriptor support
OLE DB support
External Linked Server support
Data Link support for Data Transformation Services
Specifically I am hoping to find out when each technology should be used and the types of applications that use them. Additionally, I am wondering if there are alternatives to these technologies and why they may have been used instead.
Any guidance/feed back is appreciated.
Thanks,

Set myConn1 = Server.CreateObject("ADODB.Connection")
Set myRs1 = Server.CreateObject("ADODB.Recordset")
Can anybody tell me what the ADODB in these two statements is telling me?

hi!
I want to store the value of the Connection String in an Common table exisiting for the whole project and retrieve it for the whole package to Run. I want to know if there is a way of doing this.
I do not want to have a config file which is created trhough the package configuration.
In case of Parent package variable the Value of the variable needs to exist which again needs to execute the SQL Task which requires a connection string.
In case of Environment variabIe.I have very less knowledge about the environment variable . Even if we store it? how can we access it and change it in client place.
In case of SQL server . Can we store in an existing table. what is the configuration filter? what is the vlaue for it.
I do not want to execute any command line.............................
Thanks,
jazz

I setup alias both sql server 2005 and 2005 to communication cross wide area networks.
I cannot use ping and telnet command to validate the network layer connection.
The only tool that I can use is netstat -an.
Questions.
When I netstat in sql 200 server. Should I see the ip address of sql server 2005 show up like 55.121.161.32: 1433?
So far I saw different pot show up like 55.121.161.32. 4344.
I am newbee dba and the network guy keeps telling me that I should use telnet.
Please advise. Thank you.

Environment:
Windows Server 2003 Standard Edition Service Pack 1
ASP 3.0
SQL Server 2005 Express
(Was running SQL Server 2000)
I am having problems with the connection string.
After installing SQl Server 2005 Express, the old connection string failed.
Conn="DRIVER={SQL Server};SERVER=servername;UID=userid;PWD=pass;DATABASE=dbname"
I created the following DSN in ODBC...
Conn="DSN=dsnname;UID=userid;PWD=pass;DATABASE=dbname;APP=ASP SCRIPT"
...it works but I am seeing error messages...
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC SQL Server Driver][Shared Memory]SQL Server does not exist or access denied.
Question One:
Why is the first connection string failing?
Question Two:
Is the above error message related to using ODBC or is it related to Win Server SP 1?
Thanks in advance.

I'm trying to create a custom connection manager and I have ConnectionType in the DtsConnection attribute set to "MSMDM". When I tried to create one in a package I got:
The connection type "MSMDM" specified for connection manager "{A8543B4B-41D9-4E69-9580-3D1A491AD719}" is not recognized as a valid connection manager type. This error is returned when an attempt is made to create a connection manager for an unknown connection type. Check the spelling in the connection type name.
(TestHarness1)
So, a few questions:
What are the valid connection manager types?
Why can I not create a new connection manager type of my own?
If I cant create new connection manager types then the purpose of being able to build custom connecton managers is defeated. Hence, what's the point in giving us the ability to create custom connection managers?

All:
I am writing an Internet/Extranet based (ASP.Net 2.0) web application that uses SQL server 2005 as the database. I am using forms authentication on my web application. I am also storing the connection string to SQL server in my web config file. The conn string is encrypted using DPAPI with entropy. I currently have created a SQL login account on my SQL server for use by the web application. This is the user ID I am using in my conn string. The reason for this is because all persons using the application will NOT have a windows login.
Here is my question: The login I created currently has defaulted to the "dbo" role and therefore has "dbo" rights to the database. I want to setup up this login account so that all it can do is execute stored procedures. I dont want this SQL login to be able to do anything else. In my application I am using stored procedures for ALL data access functions, via a data access layer in my application. Can someone guide me step by step as to how to setup this type of access for this SQL login.
Thanks,
Blue.

I have a SQL Server 2005 database (called BDHSE) in a PC which i call PC1. I have a second PC (PC2) and both are within a network (a WLAN).
What i want is to have access to BDHSE from an application in VB6 (APP1) running in PC2. All the INSERT, DELETE, UPDATE records process is done through APP1.
APP1 ia currently running in PC1 and is to be installed on PC2.
I have these questions:
1. What do i need to install in PC2 since all the INSERT, DELETE, and UPDATE is done using APP1? I guess i only have to install the Microsoft SQL Native Client (with all the prerequisites of course) but i am not sure.
2. In the APP1 made in VB6, do i have to change the connectionstring since i am accesing the database which physically is at PC1 and the APP1 will be used in PC2?
3. Any advice you can give me on doing this will be well received.
Thanks in advance,
BSc Fernando Martinez

Hi,
I plan to implement UDT for division methods.
The following fragment TSQL with zero check:
DECLARE @a int, @b int
SELECT
CASE WHEN @b = 0 THEN NULL
ELSE @a / @b
END
Clr UDT may look like this and script will be shorter.
DECLARE @a int, @b int
SELECT @a Type :: divide(@b)
Is that better to use UDT ?
Anyone have try this before?

I am looking for a good method to do table lookups in a 2003 SQL database. I am retrieving products from an item table and then want to do value lookups in related tables in the same database like category name, category type, brand name etc. These values are referenced in the item master file by guid links to related tables.I am using a datareader to loop through the Select records and then I am writing results to a tab delimited data file for a data conversion. I am limited to net 1.1 and so can't use the 2.0 executescalar for single lookups.What would be the more efficienct method to use?'Dim myItemData As New DataReader Dim myItemReader As SqlClient.SqlDataReaderDim myItemCommand As New SqlClient.SqlCommand Dim myConnection = New SqlClient.SqlConnection("server=sql01.xxx") myItemCommand.Connection = myConnectionmyItemCommand.CommandText = "SELECT ""mf_items"".""item_guid"", ""mf_items"".""item_description"", ""mf_items"".""item_wholesale_price"", ""mf_items"".""item_description_title"",""mf_items"".""item_cd"",""mf_items"".""category_guid"" FROM ""CDB006"".""dbo"".""mf_items"" WHERE ""mf_items"".""item_closed"" = 0 And ""mf_items"".""item_visible"" = 1 AND ""mf_items"".""item_available"" = 1"myItemCommand.Connection.Open()myItemReader = myItemCommand.ExecuteReader()Dim myfileout As StreamWritermyfileout = File.CreateText(Server.MapPath("out.txt"))myfileout.WriteLine("link" & vbTab & "title" & vbTab & "description" & vbTab & "price" & vbTab & "image_link" & vbTab & "category" & vbTab & "id")While myItemReader.ReadIf myItemReader.Item(4).ToString() > "" And Val(myItemReader.Item(2).ToString) > 0 Then'what method to to look up for example the category name using the category_quid referenced in the item master'Write out record for parts file

I'm fiddling around with my sql server in my home computer. I would like to store a different image in each row of the product table (for example). All the pics are now in my hard disk. I gather from various discussion boards that there are several ways of saving images -
1. INTERNALLY
a)Use VB. Run in ISQL/w
b) Use insert statement. INSERT INTO EMP(empno,empname ,Picture_Id)
VALUES('E1235','Anthony','c:PhotosAnthony.jpg')
c) Use isql/w & TSQL statement
d) Use sqlgetdata and sqlputdatn
e) Use textcopy in binn directory.
f) Use VB & ADO
2. EXTERNALLY
a)store the image externally and simply store the path to it in a plain
varchar variable.
My questions are :-
(i) Can I save images simply using 1b)?
(ii)Is 2a) correct ? Do I just type the name of the image file in my harddisk as the value in the table ?
(iii) If I have the database linked to the internet and have it hosted by a commercial server in the future, will I have a nightmare reentering all the path names when I upload the database into the commercial server?
(iv) What are the pros and cons of the various methods listed in 1.

Everytime I attempt to restore the master database, it corrupts the entire instance of SQL server 2000. I have been using the method out on Microsoft's Knowledgebase:
http://support.microsoft.com/kb/822852/en-us
using sqlservr.exe and the switches -c -m -T3608 -T4022
I would like to know if anyone has other methods of restoring the master database from a backup device.

I have developed the SSIS project, but I have a problem with deployment. My users are statistic people and SSIS packges they use are cleaning the raw data for them. Since they would like to run this SSIS package by themselves whenever they want, I need some deployment method that is easy for them to run (they are really not IT oriented people). The problem I encountered is that there is no visual studio (integration service client) installed on there computer, but they are allowed to access several dbs and server on the net.
Can someone tell me what is the best solution for this type of deployment?

Hello,
I have a dll which is developed in C#. I have made a reference to it from Reporting Services under Report Properties.
My problem is, that the methods in this dll are not static. Therefore under the Classes in Report Properties I have written the class-name and the instance-names of the instances that I need to use from this class (as I understand it, this is what you have to do if using non-static methods). In a text-box, I call one of the instances in the class, but I get this error:
[rsInvalidName] 'MyMethod()' is not a valid code class name. Names of objects must be CLS-compliant identifiers.
What exactly have I done wrong here?
Thanks
/Peter

Lets say you want to offer users access to a table that has over 1,000,000 records in it. You dont want to fetch the entire table into a dataset. Even with paging, it will still cause a performance lag, will it not ?Lets say there was a column that held last names. You could then divide up all the data in to alphabetical groups by letter. That will at least let you split up the data 26 different ways (letters in teh alphabet). Thats still roughly 38,000 possible records in the dataset at any given time. I suppose since the database and web server are very close to each other, physically, the latency shouldnt be too bad. However, Im worried about having several dozen or more users, each requesting datasets with tens of thousands of records. That would cause the memory use on the web server to spike most likely. Right now, its just one user do this sort of processing, but that might grow to include several dozens.ideas ?

In order to update a MSSQL table, named [Table_1]. The procedure is:
(@id int,@Field0 nvarchar(1000) = NULL,@Field1 nvarchar(1000) = NULL,... ...@Field9 nvarchar(1000) = NULL)Method 1:
UPDATE Table_1SET Field0 = CASE WHEN @Field0 IS NULL THEN Field0 ELSE @Field0 END, Field1 = CASE WHEN @Field1 IS NULL THEN Field1 ELSE @Field1 END, ... ... Field9 = CASE WHEN @Field9 IS NULL THEN Field9 ELSE @Field9 ENDWHERE id = @id
Method 2
IF @Field0 IS NOT NULL UPDATE Table_1 SET Field0 = @Field0 WHERE id = @id ... ... UPDATE Table_1 SET Field9 = @Field9 WHERE id = @id
Method 3:
DECLARE @SQL nvarchar(max)DECLARE @NeedComma bitSET @SQL = 'UPDATE Table_1 SET 'SET @NeedComma = 0IF @Field0 IS NOT NULL BEGIN IF @NeedComma = 1 SET @SQL = @SQL + ', ' SET @SQL = @SQL + 'Field0 = @Field0' SET @NeedComma = 1 END... ...IF @Field9 IS NOT NULL BEGIN IF @NeedComma = 1 SET @SQL = @SQL + ', ' SET @SQL = @SQL + 'Field9 = @Field9' SET @NeedComma = 1 ENDSET @SQL = @SQL + ' WHERE id = @id'EXEC sp_executeSQL @SQL, N'@id int,@Field0 nvarchar(1000), ... ... , @Field9 nvarchar(1000)', @id = @id, @Field0 = @Field0, ... ... , @Field9 = @Field9

Let me see if I can explain what I'm trying to do (actually am doing now but with methods that I know can improve), and hopefully someone can give me some thoughts on the best way to do this (for maximum speed).
I've got data that comes from a couple of different sources that I'm updating and compiling nightly. On each file there can be different fields of data (some memo fields, some numbers, some text, etc. but all a subset of a master list of fields in my table). I then need to take that data and basically update my existing records (or insert new records if they don't exist based on an id which is in the incoming files). The current program does this all by looping through the data and creating sql statements for the inserts and updates. I think using SSIS or bulk inserts after writing my data to a file, i should be able to speed this up.
To me the "gotchas" are that each file may have different columns of data and I can't write different imports for each one. So I either have to have it be able to determine the columns for each piece of data and match when loading or updating or I could recode my program to basically insert the missing columns (should be doable).
Any thoughts on the best way to do it? Writing out to a file for SSIS to use but having it only write out new records and then doing updates through another method or ? I know SQL Server 2005 fairly well for basics on SQL but haven't used SSIS so will have to learn or outsource so any good starter points or tips would help. Seems the updates are where I'm a bit more confused on the very best way to do it.
I'm also stripping out html in one of the fields and creating a secondary field that doesn't have the html so I'm assuming the best is probably to do that while writing out the file I may use for whatever system but if there is a way to do it inside SQL or SSIS and make it happen quickly (so it doesn't lock the database) that would be great.

I need to move total of 50 DTS packages from SQL 2000 to SQL 2005.Could someone give me the best way to do this ?
Do I need to just save the package onto the new server OR do I use the DTS package migration wizard.
What are the problems that can arise ?

We have roughly 5000 methods generated into C# that need to get assembled into DLLs and then put out as assmeblies in a SQL Server database. We then intend on creating user-defined functions to call many of these directly.
We can break these 5000 down into bundles and make about 10 DLLs, OR we can make 5000 DLLs. What are the concerns from a run-time perspective ??
If we go with 5000 DLLs, will an end user performing a few ad-hoc queries that use these user-defined functions experience poorer performance than if we had 10 large DLLs ?
Any input is appreciated. We'll be trying to assess the performance ourselves, but I'm looking for any stories about using large numbers of DLLs.
Thanks
Scott

Hi, please excuse me if this seems like a daft or badly formed question.
A colleage mentioned that when constructing the where clause in a query that it was important what order the criteria were entered. They weren't sure themsleves but the idea was that starting from the bottom of the query you should add the criteria that will have the effect of reducing the data the most and then work 'up' the query back to the from clause.
As a dodgy example, if you have a staff table and you want to run a specific query on all staff over 75 that are male, then:
where gender = "male"
and age >- 75
The reasoning being that the age criteria would reduce the size of the data being worked on more than the gender criteria.
It's been a while since I've had to look at intermediate tables etc but i'm pretty sure this suggestion will not make any difference to the performance of a query.
Thanks,
Matt

Hi all,
The problem is: when you're trying to call in method MyMethod anonymous method that doesn't use local variables, deployment of the assembly will fail referring that MyMethod tries to store smth. in the static variable. Indeed, looking at the compiled CLR code, you can see that anonymous delegate is cached in the private static delegate and the call looks like:
If(ClassName.privateStaticDelegate == null)
ClassName.privateStaticDelegate = new MyDelegate(HiddenMethodName);
CallAnonymousMethod(ClassName.privateStaticDelegate);
Is there any workaround to fix this problem.
P.S. I googled about this problem and found only one article on it:

Hello,I have to implement a method FindProduct, which takes a parameter search query and returns product based on the query.I think i can use full text search here but don't know how. I tried to read a various way but could not figure out. 1
2
3 [DataObjectMethodAttribute(DataObjectMethodType.Select,true)]
4 public DataLayer.shopDBDataSet.ProductsDataTable GetProducts()
5 {
6 return Adapter.GetProducts();
7 }
8
9 [DataObjectMethodAttribute(DataObjectMethodType.Insert, true)]
10 public bool AddProduct(string UPCCode, string Description, string Size)
11 {
12 shopDBDataSet.ProductsDataTable products = new shopDBDataSet.ProductsDataTable();
13 shopDBDataSet.ProductsRow productRow = products.NewProductsRow();
14
15 productRow.UPCCode = UPCCode;
16 productRow.Description = Description;
17 productRow.Size = Size;
18
19 products.AddProductsRow(productRow);
20 int rowsAffected = Adapter.Update(products);
21 return rowsAffected == 1;
22 }
23
24 [DataObjectMethodAttribute(DataObjectMethodType.Delete, true)]
25 public bool DeleteProduct(string UPCCode)
26 {
27 int rowsAffected = Adapter.Delete(UPCCode);
28 return rowsAffected == 1;
29 }
30
31 [DataObjectMethodAttribute(DataObjectMethodType.Select, false)]
32 public DataLayer.shopDBDataSet.ProductsDataTable FindProducts(string searchQuery)
33 {
34
35 throw new System.NotImplementedException();
36
37 }
38
You can see the method at line number 32. I could not figure out the way to implement it although i know full text search is a good choice.I have following table adapterGetProducts(); GetProductsByManufacturerName(); GetProductsByManufacturerID(), and GetProductsByUPCCode();Product table contains UPCCode, Description, Size columnsBut i need to get the product which returns the description containing search query. I know some of you have done something similar to this. Could you please guide me....Thanks in advance....
