Get Data From A SQL View Using ADO.Net
Feb 19, 2008
When using ADO.Net to retrieve data from SQL Server into a SQLDataReader I use this code in a Data Access class:
public SqlDataReader GetView(string ViewName)
{
SqlConnection myConnection = new SqlConnection(ConnectionString);
SqlCommand myCommand = myConnection.CreateCommand();
myCommand.CommandText = ViewName;
myCommand.CommandTimeout = 120;
// Mark the Command as a SPROC
[COLOR="Red"]myCommand.CommandType = CommandType.StoredProcedure[/COLOR];
// Execute the stored procedure and Return the datareader result
myConnection.Open();
return myCommand.ExecuteReader(CommandBehavior.CloseConnection)
This works fine when I am getting the data from a Stored Procedure.
But, on this occasion, I want to get the data from a View. How can I do this? There does not seem to be an option of CommandType.View
Thanks for any help.

I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string based
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?

Hi ! I have a textbox and a Search button. When the user inputs a value and press the button, i want a datagrid to be filled.
The following code runs:
Dim connect As New Data.SqlClient.SqlConnection( _
"Server=SrvnameSQLEXPRESS;Integrated Security=True; UID= ;password= ; database=dtbsname")
connect.Open()
Dim cmd As New SqlCommand
Dim valor As New SqlParameter("@valor", SqlDbType.VarChar, 50)
cmd.CommandText = "Ver_Contactos_Reducido"
cmd.CommandType = CommandType.StoredProcedure
cmd.Connection = connect
cmd.Parameters.Add(valor)
cmd.Parameters("@valor").Value = texto
Dim adapter As New SqlDataAdapter(cmd)
Dim ds As New System.Data.DataSet()
adapter.Fill(ds)
GridViewContactos.DataSource = ds
GridViewContactos.DataBind()
connect.Close()
I drag a datagrid on the page and only changed its Id.
Into the SQL database the stored procedure is the following:
ALTER PROCEDURE [dbo].[Ver_Contactos_Reducido]
(@Valor VARCHAR(100))
AS
BEGIN
SET NOCOUNT ON;
SELECT NombreRazonSocial, Nombre, Apellido,TelefonoLaboral,
Interno, TelefonoCelular, Email1, Organizacion
FROM CONTACTOS
WHERE NombreRazonSocial = @Valor OR Nombre = @Valor OR Apellido = @Valor OR TelefonoLaboral = @Valor OR Interno = @Valor OR
TelefonoCelular =@Valor OR Email1 = @Valor OR Organizacion= @Valor
END
When i run the page i can't see the datagrid, and after i enter a text and press the button, nothing happens. What am i doing wrong??
Thks!!

Is there a way of changing the value of a column in a view? For example, I have a table with defect code and a description (other columns as well). In a view, I would like to see only the defect code and the description, but if the code is > 90, I would like to define what the description is.
TIA

I created a view of a table like the following:
create view SomeView
as
select * from SomeTable
where SomeField > 0
I later modified the table to include more fields INTERSPERSED among the previous ones. I noticed that if I didn't recreate the view, the data was shifted if I used a select statement to query the view. I had dates associated with field names where there should be varchars, FirstNames became addresses, etc. Without naming each field in the select statement, does anyone know of a better way to create a view so that you don't have to remember which views do a "select *"?

Hello,
I am trying to add a View to an existing publication and it the subscribers (all devices with SQL CE) don't get the View after replication. I have deleted and recreated the publication, and only the tables will appear on the device, not the view.
Also, I want the data from the view to be dynamic, filtered by using the Host_Name() function/value. Will this work for a View?
thanks

HI All,
I have a three table in my data base. I created a report using some of the fields in those three tables.
Table names are as follows.
Table1 - LoanApplication
Table2 - Member
Table3 - Rate
When I want to view sm fields from all three tables, it does not allow me to do that. I can not view data in the report.
I tried a query like this.
Code Block
SELECT LoanApplication.Uuid, LoanApplication.Status, LoanApplication.Amount, LoanApplication.Term,
LoanApplication.SubmittedOn, Member.LastName, Member.FirstName, Member.MiddleName, Member.CuStatus, Member.CUMemberId
FROM LoanApplication
INNER JOIN Member ON LoanApplication.MemberFK = Member.Id AND LoanApplication.Id = Member.LastLoanApplicationFK INNER JOIN Rate ON LoanApplication.RateFK = Rate.Id
There are realtionships of LoanApplication table with Rate and Member tables. But there is no relationship between Rate and Member.
When Rate table is included in the query, problem happens. When It is excluded , I can view the data in the report.
What is the reasone for this?

Hey everyone,
I have a view that shows the email address and first name of a Membership table. I need to add a column to this view that doesn't have a corresponding column in the original table that has some default value.
i.e. the view currently shows:
John john@something.com
I need it to say:
John john@something.com EmailBlast
The third column will always have that value.
Anyone have a suggestion?
Thanks in advance!

I've created a SQL View in SQL 2000 using a table that has columnsdefined as Numeric data type. In the view, I am grouping and summing.When I link the view via ODBC to Access, all of the data types arechanged to text. If I link the original table which the views arecreated from to Access, the data types are correct. So this problemobviously happens when I change the view to Group. Is there a wayaround this? I want the data types to be correct in Access when Ilink to the views.thanks,jim

Hi all,
I am really new to SSIS, so may be this is a really simple question, but I couldnt find an answer yet.
I need to build a package that
1) counts the rows from a view
2) if rowcount >0 extracts the data into a file
I tryed to do this using a Row Count Transformation in the data flow, but after putting the count in a variable I am not able to perform the "conditional" phase two.
I mean that I want to check the value of the variable, but cannot figure out how to conditionally execute the flat file extraction.
Using Row Count, I have to build 2 data flow tasks.
Is there a way to do this in a single data flow?
May be using an Execute SQL Task instead of row count?
Any suggestions will ge greately appreciated

OK,
I have two data tables where depending on the time line item it is, it needs a different join.
So, it's like this:
Table Credit Card
Table Memo
If Credit Card is VISA, join on column A
If Credit Card is MA, join on column B
So, I created two views. One view has all the info joined on column A. The other view has all the info joined on column B.
How do I create a third view that will output all the data from View A and View B without making it into a cartesian product?
I can't change the table structure due to legacy application/data issues.
Thanks!

Hi, I'm developing a fresh SQL DB which is result of a deep analysis of an old Access DB. THe thing is, this old one had very complex consultations to the Access tables, and some consultations were using another consultations as way to select some specific data. THe ideia in SQL is to avoid that too, however, there are some data that may serve exactly the same to some bigger stored procedures. This way, I have three options I guess: 1. Create every stored procedure making select queries directly to the table and it's done!2. Create auxiliary stored procedures which will select the redundant data, and when it is needed, another stored procedures call this one and use its returned data. (is this possible anyway?).3. I create a view to this redundant data, and the greater depth stored procedures access this data of the view when needed. I've heard, however, that a select to a view is slower than directly to the table, once the view adds an extra query to the process.. What is your guess on this issue of mine?I'm almost sure that option 1 is the best, however, I'd love to hear from you guys your opinion on this. The greater issue above this all is just one - performance. Thanks a lot!

I have written following SQL query, this creates temporary table, inserts rows into it. I need to create VIEW "vw_NumberOfAttachments" in the database. I initially created table using "CREATE TABLE" but then i got error as VIEW can not be filled by temporary table. Hence I am using DECLARE TABLE
--------------------------------

CREATE PROCEDURE sp_GetViewNumberOfAttachments

DECLARE ATTACHMENT_CURSOR CURSOR

FETCH NEXT FROM ATTACHMENT_CURSOR INTO @emailMessageID, @metaDataStorageID
WHILE @@FETCH_STATUS = 0
BEGIN
-- here the table name need to get dynamically the name of the attachment table

set @numberOfAttachments = (SELECT count(*) FROM ppaMsOfficeDoc WHERE metaDataStorageID = @metaDataStorageID)
INSERT INTO @AttachmentDetails(emailMessageID, metaDataStorageID, numberOfAttachments)
VALUES (@emailMessageID, @metaDataStorageID, @numberOfAttachments)
FETCH NEXT FROM ATTACHMENT_CURSOR INTO @emailMessageID, @metaDataStorageID

CLOSE ATTACHMENT_CURSOR
DEALLOCATE ATTACHMENT_CURSOR

DROP VIEW vw_NumberOfAttachments
GO
CREATE VIEW vw_NumberOfAttachments
AS
SELECT @AttachmentDetails.emailMessageID, @AttachmentDetails.metaDataStorageID, @AttachmentDetails.numberOfAttachments
FROM @AttachmentDetails
GO
END
GO

I am getting following errors:
-----------

Hi everyone,I have 5 servers, all with identical databases just different data. Ihave a rather lengthy SQL statement (in a View) to hit one database andpull-in certain data, but I'd like to somehow run this same SQLstatement within the view but hit all 5 servers so we don't have 5different versions of this data to mess with.I'm not opposed to creating an update query in a stored procedure tohit all 5 databases and update a table or even do this within a DTS,but I'd prefer to keep it as simple as possible and as dynamic so theusers can simply run the view and get live data anytime based on all 5tables.Is this possible ???Thanks,rlangly

How does the report model know what data source view to use? I could not find it defined anywhere in the .smdl file.
My problem is this. I have a Report Model project with two data sources, two data source views and multiple report models. When I try and bind a data source to an entity in the report model I do not get to choose which data source view to use to choose what table/view I want to bind the entity too and only the tables in one of my DSV's shows up. When I first created it, it worked fine. It automatically selected the correct view and table and was successfully created but now when I open the project, that correlation is lost.
Any suggestions or help is appreciated, thanks.

Is there a limit on the number of fields that can be displayed in a table object in a data source view in SSAS 05?
One of the tables (the fact table) in my data source view is displaying only 50 fields. The table actually has many more than that. One of the fields that is not displaying is a foreign key that I need to link to a new dimension table. I have tried refreshing the view, but it doesn't bring in any additional fields.
