SqlDataSource, DataView, CType Function && Page_Load-Compilation ErrorBC30451: Name 'SqlDataSource3' Is Not Declared.
Nov 7, 2006
Hi all,
In my VWD 2005 Express, I created a website "AverageTCE" that had Default.aspx, Default.aspx.vb and App_Code (see the attached code) for configurating a direct SqlDataSource connection to the dbo.Table "LabData" of my SQL Server 2005 Express "SQLEXPRESS" via SqlDataSource, DataView, CType Function and the Page_Load procedure. I executed the website "AverageTCE" and I got Compilation ErrorBC30451: Name 'SqlDataSource3' is not declared:
Server Error in '/AverageTCE' Application.

I have 2 questions to ask:
1) How can I fix this Compilation Error BC30451: Name 'SqlDataSource3' is not declared?
2) I just read MSDN Visual Studio 2005 Technical Article "Data Access in ASP.NET 2.0" and I saw the following thing:
Types of Data Sources:
SqlDataSouirce: The configuration of a SqlDataSoure is more complex then that of the AccessDataSource, and is intended
for enterprise applications that require the features provided by a true database management system
(DBMS).
I am using the website application in VWD 2005 Express to do the task of extracting data values from the Tables of SQL Server 2005 Express via .NET Framwork, ASP.NET 2.0 and VB 2005 programming. Can VWD 2005 Express be configured to SQL Server 2005 Express (SQLEXPESS) for the SqlDataSource connection and do the data-extraction task via DataView, CType Function and the Page-Load procedure?
Please help, respond and answer the above-mentiopned 2 questions.
Many Thanks,
Scott Chang

hello all
1) I was using SQLdataSource and bind it with the gridviw to show its data. so that is how is running
when the page load, i see the data is posted on the page on the gridview.
But what i need to do when I want a user to click a button and then the Gridview show the data.
As i was creating a SQLDatasource, it was click click and click but I want to put that sqldatasouce to load the data in gridview by a click event.
2) my second question is also related to the first one or just similar.
I dont want to get all the data rather filter it.
so once the page load, there is a button and a text box.
In the text box user going to type the EmployeeID and click the "Employee Info" button and then the data would show up.
Rather i use te DetaildView Control . What should I do to load the information on the Text boxes rather then on the GridView since it is going to be a single recrod.
Thanks all

I am creating an ad-hoc reporting module for my website. The user may select a list of columns and specify the WHERE for the report. I build the select statement and the where statement and pass the info to a stored procedure. The stored procedure accepts 3 select parameters and a 3 wherestmt parameters. I finally got the SQLDatasource to work by setting the parameter values in the Selecting method of the SQLDatasource. Binding it to a gridview shows me all my values. Now, I am trying to programmatically call the select method of the SQLDatasource so I can get a dataview or datareader to manipulate further. I am getting an null back when I call the select method. Any ideas why? or a workaround?

Here is one such function:CREATE FUNCTION my_max_market_date () RETURNS datetimeBEGINDECLARE @mmmd AS datetime;SELECT max(h_market_date) INTO @mmmd FROM holdings_tmp;RETURN @mmmd;ENDOne change I had to make, relative to what I had working in MySQL, wasto insert 'AS' between my variable and its type. Without 'AS', MS SQLinsisted in telling me that datetime is not valid for a cursor; and Iam not using a cursor here. The purpose of this function is tosimplify a number of SQL statements that depend on obtaining the mostrecent datetime value in column h_market_date in the holdings_tmptable.The present problem is that MS SQL doesn't seem to want to allow me toplace that value in my variable '@mmmd'. I could do this easily inMySQL. Why is MS SQL giving me grief over something that should be sosimple. I have not yet found anything in the documentation for SELECTthat could explain what's wrong here. :-(Any ideas?ThanksTed

Hi i have two stored procedures that need to run on page load, how will i go about doing this, thank you. Here is my code;protected void Page_Load(object sender, EventArgs e)
{if (!IsPostBack)
{SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["streamConnectionString"].ConnectionString);
SqlCommand command = new SqlCommand("retrieve_Articles", conn);command.CommandType = CommandType.StoredProcedure;
conn.Open();SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
ArticleList1.DataSource = reader;
ArticleList1.DataBind();
reader.Close();
}
}
The above loads up the article datagrid, how can i now load up my news section which has the following code;SqlConnection conn2 = new SqlConnection(ConfigurationManager.ConnectionStrings["streamConnectionString"].ConnectionString);
SqlCommand command2 = new SqlCommand("retrieve_News", conn);command2.CommandType = CommandType.StoredProcedure;
conn.Open();SqlDataReader reader2 = command.ExecuteReader(CommandBehavior.CloseConnection);
NewsList1.DataSource = reader2;
NewsList1.DataBind();
reader.Close();
}

Procedure or function sp_AddDealer has too many arguments specified.
I am experiencing the 'too many arguments specified' error. I am running on SQL 2005. The Parameters lists on SQL server (when I view a dropdown under the sp name) shows a 'returns integer' (but without the @ the signifies a parameter).I have looked around the forums and haven't seen quite this flavor of this error. My forehead is sore from beating it against the wall... any clue would be appreciated!
The error occurs when I click the 'new' link button, enter some data and then click the update link button after ... BOOM - Procedure or function sp_AddDealer has too many arguments specified.
Thanks!!

Here is the stored Procedure:

Hello,
I am using a sqldatareader to get back a whole set of data.
The columns are id, data_id and data_desc
for example, the collection is id data_id data_desc0 100 this is name for id 00 101 this is address for id 00 102 this is gender for id 01 100 this is name for id 11 101 this is address for id 11 102 this is gender for id 12 100 this is name for id 22 101 this is address for id 22 102 this is gender for id 23 100 this is name for id 33 101 this is address for id 33 102 this is gender for id 3
I want to be able to go thru' this list and break up for each id and create a txt file. So, i will have four text files.
txt0.txt will contain100, this is name for id 0 101, this is address for id 0102, this is gender for id 0
I would like to know, how do i use a dataview to break up the sqldatareader so i can then repeat the loop for each id and generate the text file.
I don't have a problem generating the text file.
Please let me know, how should i go about it.
Thanks a bunch,-Sean

I don't know if this topic should go in this forum category or in the SQLDataSource forum.
I need to be able to provide SQL which varies based on what the user enters on a page. However, this isn't as simple a providing parameters in the SQLDataSource control because the SQL changes depending on what the user selects. For example, in a customer search page, they choose to search by either first name or last name from a drop down list and then enter the name to search for in a text box. The dataview should display the matching customers.
How can I set this SQL based on the entered values while also keeping the paging and sorting capabilities of the dataview? You don't seem to be able to set the SQL for an SQLDataSource at run time.

In the dataview rowfilter property, how can I say that I just wantTitles that start with 'A' to 'J' ??ex:dv.rowfilter = " Country = ' France ' "I wantdv.rowfilter = " Title = (from 'A' to 'J') "This doesn't work :dv.rowfilter = " Title like '[a-j]%' "Neither does :dv.rowfilter = " Title like 'a%'" AND "Title like 'b%'" AND..so onBut this does work just for the Titles starting with 'a'dv.rowfilter = " Title like 'a%' "any idea ?JMT

Hi,
I use a filter on a dataview which has uniq rows. I need to bind several fields of the result filtered row to textboxes. Here the code :
protected void Page_Load(object sender, EventArgs e) { string id = Request.QueryString["id"];
if (PreviousPage != null) { SqlDataSource dsPrev = (SqlDataSource)PreviousPage.FindControl("SqlDataSource1");
DataView dv = (DataView)(dsPrev.Select(DataSourceSelectArguments.Empty)); dv.RowFilter = "dr_id='" + id + "' "; dv.RowStateFilter = DataViewRowState.CurrentRows;
txtFirstName.Text = // ??? FirstName Field
txtLastName.Text= // ??? LastName Field
txtAddress.Text= // ??? Address Field } }
I don't know which cod to put in those lines.
On the help of the dataView there is an example that use DataBindings. This example is in the DataView.RowFilter article:
Text1.DataBindings.Add("Text",view,"CompanyName");
The big problem is that I don't have a method or event call 'DataBindings'. I just have 'DataBind' method or dataBinding event and they both don't support the 'Add' method.
So how can I bound those controls to my filtered Dataview field value.
Thanks,
David

Made a table and a UI form according to this lesson (table colums: CustomerID, FirstName, LastName).
Is it possible to use the same or an identical looking query form to find "Bob" by typing Bob in the Fist Name textbox or "Tabor" by typing Tabor in the Last Name textbox as in FileMaker?
Thanks,

Hi, I need to create filter which retrieves data for current moment. [time].[date].lastchild is not an option because the calender in database is generated till following year (2008).
I guess script goes like..
[time].[date].currentmember
but it does not work.
I'm green with these MDX scripts.. I'd be very pleased if some one of you gurus could help me.
Best Regards,
Eeva

I have the following SqlDataSource in my page:<asp:SqlDataSource ID="sqlds" runat="server" ConnectionString="<%$ ConnectionStrings:cs %>" SelectCommand="SELECT [Quest1], [Quest2], [Quest3], [Quest4], [Quest5] WHERE ([QuestID] = @QuestID)"> <SelectParameters> <asp:Parameter Name="QuestID" /> </SelectParameters> In my code I get the following error: "Cannot convert type 'int' to 'System.Data.DataView'", I don't understand why I am getting this error because I am casting my SqlDataSource as type DataView when passing it to my DataView type.Code: protected void Chart(string record) { System.Data.DataView dv = (System.Data.DataView)sqlds.SelectParameters.Add("QuestID", System.TypeCode.Int32, record); //Error line ... ... ...}If anyone could point me in the right direction I would be very grateful.

I'm trying to connect to an SQL database through my asp.net page and I'm getting an Compiler Error Message: BC30188: Declaration expected for the following codes:
DBConn= New OledbConnection("Provider=sqloledb;" _
DBInsert.Commandtext = "Insert Into GuestInfo" _
DBInsert.Connection =DBConn
DBInsert.Connection.Open
DBInsert ExecuteNonQuery()
What I'm trying to do is connect to the SQL database and input new information to the database.
This is the entire code for connecting and entering info into the database. The SQL Database's name is HMS. I'm stuck and I can't figure it out.
Dim DBConn as oledbConnection
Dim DBInsert As New oledbCommand
DBConn= New OledbConnection("Provider=sqloledb;" _
& "server=localhost;" _
& "Initial Catalog=HMS;" _
& "User id=sa;" _
& "Password=yourpassword;")
DBInsert.Commandtext = "Insert Into GuestInfo" _
& "(FirstName,Lastname,Address,City,State,Zipcode) values ('" _
&"'" & txtFirstName.Text & "', " _
&"'" & txtLastName.Text & "', " _
&"'" & txtAddress.Text & "', " _
&"'" & txtCity.Text &"', " _
&"'" & txtState.Text &"', " _
&"'" & txtZipCode.Text &"', ")"
DBInsert.Connection =DBConn
DBInsert.Connection.Open
DBInsert ExecuteNonQuery()

Hi,I'm using SQL Server 2000 MSDE on a laptop running Windows XP.I have a couple of SP's that that quite some time to compile. So I waswondering: is there any way to have the database *not* recompile them everytime after a reboot?BOL says: "As a database is changed by such actions as adding indexes orchanging data in indexed columns, the original query plans used to accessits tables should be optimized again by recompiling them. This optimizationhappens automatically the first time a stored procedure is run afterMicrosoft® SQL ServerT 2000 is restarted."Now the SQL Server is restarted a lot, because laptops don't have endlessbatteries <g>Cheers,Bas

Using small stored procs or sp_executesql dramatically reduces the number ofrecompiles and increases the reuse of execution plans. This is evident fromboth the usecount in syscacheobjects, perfmon, and profiler. However I'm ata loss to determine what causes a compilation. Under rare circumstances theusecount for Compiled Plan does not increase as statements are run. Seemsto correspond to when there is no execution plan. It would seem to me thatcompilation is a resource intensive task that if possible (data and schemaare not changing) should be held to a minimum.How does one encourage the reuse of compile plans?Is this the same as minimizing compilation?Looks like some of this behavior is changing in SQL 2005....Thanks,Danny

I need access to the underlying DataView associated with a declaratively defined SQLDataSource. Ideally, I need this access in the SQLDataSource's Selected event. I know that I can use the SQLDataSouce.Select() method to return the underlying DataView object. But, there is a GridView control bound to the datasource so I don't want to explicity call Select() since it will end up being called again implicity by the gridview itself. I have seen that this can be done with an ObjectDataSouce as follows:
void odsDataSouce_Selected(object sender, ObjectDataSourceStatusEventArgs e) { DataView oDV = (DataView)e.ReturnValue;}
Is there any way to accomplish the same thing with a SQLDataSouce? It seems hard to believe that the query results are not exposed to the Selected event.
Thanks!

(Hope this isn't a "stupid" question, but I haven't been able to find a straight-forward answer anywhere)"
I currently have code that iterates through a dataview's records, making a change to a field in some of the records. The way I have this coded, a conection has to opened & closed for each individual record that's updated:
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then intCorrect = 1 Else intCorrect = 0 End If dsrcUserIae.UpdateParameters.Item("blnCorrect").DefaultValue = intCorrect dsrcUserIae.UpdateParameters.Item("ID").DefaultValue = myRow("ID") intUpdateResult = dsrcUserIae.Update() Next
It seems like I should be able to do something like this (call update once), but I'm not sure how...
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then myRow("blnCorrect") = 1 Else myRow("blnCorrect") = False End If Next
intUpdateResult = dsrcUserIae.Update() 'Want all changed myRow("blnCorrect") to be updated to datasource
Can anybody explain how to do the bulk update? I've seen some info about AcceptChanges and Merge, but I'm not sure if they apply here, or if they more for Transactions.

Hi,
I would like to know if the execution plans of stored procs also get migrated when we do migration to 2005 from 2000 using attachdetach method or we will need to re-run the stored procs?
The thing is when I am running the Stored procs in 2005, its performing really slow in first run.
Any help in his regard is highly appreciated.
Thanks,
Ritesh

How can we say whether the SP is successfully compiled or not if we are compiling it on the server as a part of the TSQL script since it does not throw any message like ORACLE does.
In oracle, system will let you know whether the the procedure is successfully complied or not?
Thanks/

Hi all,
I€™m having a test regarding to the image data type. The test program is written with sql native api and just update the image data type column, but I looked the SQL Compilations/sec and Batch Requests/sec counters in SQLServer:QL Statistics using Perfmon, both values are almost the same. It seemed whenever the stored procedure is called, SQLServer compiles it and makes execution plan again. But when I had a test without image data type, SQL Compilation/sec was 0. SQL version is Microsoft SQL Server 2005 - 9.00.3054.00 (Intel X86) (Build 2600: Service Pack 2).
Is SQL server working the way expected or am I missing something?

I am wondering something, once we've created a job that executes a package at a given time interval, does that package get recompiled each time the job spins up and executes the package? Or is the package compiled once and then that compiled code is executed each run after the first run?
What I'm seein is this; I have a package that reads data from flat text files and then dumps that data into the database. The package will take 3 minutes to execute when executing on a single file, but when it's looping through ~50 files, it will take ~30 minutes to execute, that is less than a minute per file. Why is this?
Hopefully I'm just forgetting something and not setting a checkbox or radio button somewhere. The job is set up as an SSIS job, not as a command line job.
Thanks in advance for any help you can give me.

I am re-writing old DTS packages(from sql 2005) to convert them to SSIS packages(sql 2014) and in one of the script task, the old activex script does not run.
The script is :
'************************
' Visual Basic ActiveX Script
'************************
Function Main()
mydate = now()
yrs = ""
mth = ""
mth = Month(mydate) - 1
yrs = Right(Year(mydate), 4)
If Month(mydate) = 1 Then mth = "12"
[code].....
Not sure how to proceed forward? I am quite new to package migration
