Error With Execute Sql Task And Full Result Set: Not Been Initialized Before Calling 'Fill'

Oct 10, 2006

This is the first time I've tried creating an "execute sql task" with a "full result set".

I've read in the documentation that I must set the resultname to 0, which is done, and that the variable must be of type object. Also done.

[Execute SQL Task] Error: Executing the query "select * from blah" failed with the following error: "The SelectCommand property has not been initialized before calling 'Fill'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

Has anyone else had success with a full result set?

Thanks,

Arithmetic Overflow Error Converting Expression To Data Type Int When Using Fill From A SqlDataAdapter

Mar 7, 2007

I thought I'd post this quick problem and answer, as I couldn't find the answer when searching for it. 
I tried to call a stored procedure on SQL Server 2000 using the System.Data.SqlClient objects, and was not expecting any unusual issues.  However when I came to call the Fill method I received the error "Arithmetic overflow error converting expression to data type int."
My first checks were the obvious ones of verifying that I'd provided all the correct datatypes and had no unexpected null values, but I found nothing out of order.  The problem turns out to be a difference on the maximum values for integers between C# and SQL Server 2000.  Previously having hit issues with SQL Server integers requiring Long Integer types in VB6, I was aware that these are 32-bit integers, so I was passing in Int32 variables.  The problem was that Int32.MaxValue is not a valid integer for SQL Server.  Seeing as I was providing an abitrary upper value for records-per-page (to fetch all in one page), I was simply able to change this to Int16.MaxValue and will hit no further problems as this is also well beyond any expected range for this parameter.
 If anyone can name off the top of their heads what value should be provided as a maximum integer for SQL Server 2000, this might be a useful addition, but otherwise I hope this spares others some hunting if they also experience this problem.

Data Adapter FILL Causing Data Corrupt Error In C# Web Service

Apr 2, 2008

I hope someone has seen this one...I've got a very simple web method that returns a DataTable from my database. It worked fine until I changed this line of code:

string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? ORDER BY Timestamp desc";

To this line of code:

string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";


Here is the complete webmethod:

[WebMethod]
public DataTable GetConfession (int ConfessionID, int CategoryID) {

DataTable dt = new DataTable();
dt.TableName = "XMLConfession";

string SqlString = @"SELECT Timestamp, Confession FROM Confessions WHERE ConfessionID = ? AND CategoryID = ? ORDER BY Timestamp desc";

using (OleDbConnection cn = new OleDbConnection (ConnectionString)) {
using (OleDbCommand cmd = new OleDbCommand (SqlString, cn)) {

cmd.CommandType = CommandType.Text;
cmd.Parameters.AddWithValue ("@ConfessionID", ConfessionID);
cmd.Parameters.AddWithValue ("@CategoryID", CategoryID);
cn.Open();

OleDbDataAdapter da = new OleDbDataAdapter (cmd);

da.Fill (dt);
}
}

return dt;
}
To cause the error, all I did was add the AND statement into the query. Now I get this .NET error message every time I try to run this program:


System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Data.Common.UnsafeNativeMethods.ICommandWithParameters.SetParameterInfo(IntPtr cParams, IntPtr[] rgParamOrdinals, tagDBPARAMBINDINFO[] rgParamBindInfo) at System.Data.OleDb.OleDbCommand.ApplyParameterBindings(ICommandWithParameters commandWithParameters, tagDBPARAMBINDINFO[] bindInfo) at System.Data.OleDb.OleDbCommand.CreateAccessor() at System.Data.OleDb.OleDbCommand.InitializeCommand(CommandBehavior behavior, Boolean throwifnotsupported) at System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) at System.Data.OleDb.OleDbCommand.ExecuteReaderInternal(CommandBehavior behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.OleDb.OleDbCommand.System.Data.IDbCommand.ExecuteReader(CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)

I am using SQL Server Compact Edition 3.5 and C# .NET 2.0. It's worth noting that the web service does this outside of the program as well, so I don't think the problem is in the code that calls it. Also worth noting is that the query itself works fine when I substitute values in and run it in .NET Server Explorer.

Thanks in advance for any assistance.

Working With DataAdapter Values

Aug 14, 2007

 I have done some reading on the dataadapter class,  but do not have a good handle on how to work  with dataadapter after it has been filled by a dataset.  For instance,  should I use an if statement such as this to update the value in the dataadapter?  if (dsSunbelt.Tables[0].Columns[39].Equals(""))        {            DataRow drUpdate = dsSunbelt.Tables[0].Columns[39].Equals(DateTime.Now);        }         I am sure it is not hard to see what I am doing, and I hope that I am missing something small, but how do I isolate a dataadapter value to update in the corresponding database?

Dataadapter.Update() OR ExecuteNonQuery()

May 18, 2007

Hy, again! I am at the begining of an application. I have some modules that insert, delete and update only one row at one table. My question is should I use dataadapter.Update() or ExecuteNonQuery(). I prefer ExecuteNonQuery because I want to build a class : DataLayer to implement my own InsertProcedure(), UpdateProcedure(),DeleteProcedure(). I want speed in my application, so which is the best: dataadapter.Update() OR ExecuteNonQuery(). Thank you!

DataAdapter Always Returns 0 Or Empty Rows

May 7, 2007

 
Good day,
I just like to ask if anybody has experienced getting empty rows from SQL data adapter? I'm using SQL Server 2005. Problem is when the sql is run on Query Analyzer it retrieves a number of rows but when used in my application it returns 0 or empty rows.
I thought the connection is not the problem since I got my columns right. Below is my code snippet.
Thanks!
const string COMMAND_TEXT = @"select distinct somefield as matchcode, count(somefield) "
+ "as recordcount from filteredaccount where StateCode = 0 group by somefield having count(somefield) > 1";
SqlDataAdapter adapter = new SqlDataAdapter(COMMAND_TEXT, connection);
DataTable dt = new DataTable(sometablename);
adapter.Fill(dt);

DataAdapter.Update Updates Zero Records

Jul 13, 2004

I am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?

Create Trigger To Use AFTER DataAdapter.Update()

Feb 5, 2005

Hi,

I'm using DataAdapter.Update() to update data in a table. My question is; how do I create a trigger that works after the update has completely finished?

For example if my update adds 50 new rows to a table the trigger I've currently got fires after each new row that is added ie 50 times in total. Is it possible to get it to trigger after the last (ie 50th) row is added???

Thanks

Insert/Update Relational Tables Using Dataadapter

May 2, 2008

Hi!

I am trying to insert data into 2 different tables. I am using dataadapter and dataset.

Protected Sub SubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitButton.Click
Call ConnectionString()

Dim insertSQL As New SqlCommand()
insertSQL.Connection = sqlConn
insertSQL.CommandText = "SELECT location.CountryName, location.CityName, location.BuildingName, location.FloorID, rooms.name, rooms.FloorID AS Expr1 FROM location INNER JOIN floors ON location.FloorID = floors.id INNER JOIN rooms ON floors.id = rooms.FloorID"

Dim ds As New DataSet()
Dim da As New SqlDataAdapter()

da.SelectCommand = insertSQL
Dim scb As New SqlCommandBuilder(da)

Try
da.Fill(ds)
Dim ndr = ds.Tables("location").NewRow
Dim ndr2 = ds.Tables("rooms").NewRow

ndr("FloorID") = FloorIDDDL.SelectedValue
ndr("CountryName") = CountryNameTextBox.Text
ndr("CityName") = CityNameTextBox.Text
ndr("BuildingName") = BuildingNameTextBox.Text
ndr2("name") = RoomNameTextBox.Text
ndr2("FloorID") = FloorIDDDL.SelectedValue
ds.Tables("location").Rows.Add(ndr)
ds.Tables("room").Rows.Add(ndr2)
da.Update(ds)
ErrMsgLbl.Text = "Information saved successfully"
Catch ex As Exception
ErrMsgLbl.Text = ex.ToString
End Try

sqlConn.Close()
End Sub

The above code does not throw any error. It also does not update the tables.

Your help will be appreciated.

Thanks!

Correct Type For Operation: DataAdapter Vs. DataReader

Apr 8, 2008

I am reading multiple databases into a single dataset, putting each read into a new datatable in the set. Ultimately, I want to merge the multiple tables (they are all from different DB tables in different locations using the same schema). I am also combining this with data from an Oracle database which is in yet another table in the same dataset.

Here is my question:

I will not be propagating any changes to this data back to its original source, but I will be populating it out to Active Directory. (Don't worry; I'm not asking any AD questions here.) But I do want to run SELECT, DELETE, and UPDATE queries against the data in the dataset in memory without writing it out to a separate file. Based on that type of usage, would I be better to use a DataReader or a DataAdapter to do the read from the original database? If I use a DataReader, can I still update the data in memory? In either case, what's the correct methodology to update data in a dataset in memory?

Thanks!

My task is to bind and show 3 different values coming from three different queries into three different columns of GridView. I had done this as mention in below. Program was successful. But I want to excute these three queries in same Stored Procedure. I can do that and stored in seperated variables. I need help how to call these three different values in data adapters and store each value in three different columns of grid view.
 
Simply I want to below statement in stored procedures and call from program.  Can any one help me plz.
 
 
 
 
con = DataBaseConnection.GetConnection();
 
DataSet ds = new DataSet();

Fill Factor Fix

Apr 3, 2001

Currently we have tables (in sql 6,5), many of them do not have primary keys.
While I was trying to re-index (re-org), many of them got an error:
"fillfactor 204 is not a valid percentage; fillfactor must be between 1 and 100."
(many tables' fillfactor exceed 100 or more...)
How can I fix them so I can upgrade to sql 7 ?
Thank you for your help.

Fill Factor

Aug 13, 2001

I am really confused about this whole fill factor thing. The way I understand it, is if you have a table whose data remains pretty much static, you should use a higher fill factor. Suppose you had a database where you had at most 150 transactions a day that changed the data, should the fill factor be left at the default(0) or increased? How do you determine how much to increase it? Is there a rule of thumb that suggests if you have x number of changes against a table, you should have a fill factor between y and z percent?

Please Help

Chris

Fill Factor

Mar 12, 2001

Hi all,
While creating indexes for a table, I specified a fill factor of 70%. I then inserted a few hundred rows into the table. Is it possible to check to what percent the pages are full after the rows have been inserted?

Thanks in advance,

Fill Factor

Jul 16, 1999

You have a db with 50,000 records and you want to add 100,000 more. What should the right fill factor be? Is there a way to "calculate" a fill factor if you don't want to use default? Any help is appreciated. Thank you.
