Web Forms :: SqlDataAdapter With Parameters Causes Sql Exception 'incorrect Syntax Near'?
Jan 18, 2010This is doing my nut in,
Dim sa As New SqlDataAdapter("C_CUSTOMER_SEARCH", ConfigurationManager.ConnectionStrings.Item(1).ToString)
Dim ds As New DataSet
Dim dt As DataTable
sa.SelectCommand.Parameters.Add("LASTNAME", SqlDbType.NVarChar, 20).Value = Request.QueryString("LASTNAME")
sa.Fill(ds)
dt = ds.Tables(0).DefaultView.ToTable()
gvReport.DataSource = dt
gvReport.DataBind()
In the SQL tracer, I get:
exec sp_executesql N'C_CUSTOMER_SEARCH',N'@LASTNAME nvarchar(20)',@LASTNAME=N'smith'
An 'Incorrect syntax near' sql error bubbles upto the ASP.NET runtime. Running this in SQL studio also causes the same error. What is causing this error?
I would also like to know if its possible, to add QueryStringParameters to the SqlDataAdapter or not. I've tried (not very successfully I might add), to add QueryStringParameters programmatically to both SqlDataSource and SqlDataAdapter objects which have been created in code and not in the Markup. But each time I get 'nothing' when I call the Select() method on the SqlDataSource.
Forms Data Controls :: Dynamically Set SelectedValue In DropDownList With SQLDataAdapter?
Mar 28, 2011I have a form that's being databound with a SQLDataAdapter. I have a DropDownList with a SelectedValue='<%# Bind("FieldName")%>' on it. I was wondering if there was a way I could remove this field and set it dynamically in the codebehind and still have it insert the value of this field with the SQLDataAdapter. The reason for this is because the control I'm using doesn't have a separate InsertItemTemplate, only an EditItemTemplate which serves both purposes, and I need this to dropdownlist to only be databound on Insert.
Right now it's looking like I'll have to stop using the SQLDataAdapter and Update/Insert the data in the codebehind, but I wanted to see if there was something I was missing just-in-case.

View 3 RepliesADO.NET :: Working With Sqldataadapter & Dataset Between Layers?
Jan 14, 2011I have a theoretical question.i have a function in DAL that does a select sql query. and these are my questions:
I was told that it's not appropriate to pass datasets between layers. so how should i pass the results? which value should i return to the BLLBAL (i thought of a List<>).? and to the presentation layer.
currently my implemention is like that:
SqlCommand cmd = new SqlCommand("getRequestById", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@requestId", rId));
SqlDataAdapter datAdp = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
datAdp.Fill(ds,"getRequestById");
List<String> rs = new List<string>();
for (int i=0; i<11; i++)
{
rs.Add((Convert.ToString(ds.Tables[0].Rows[0].ItemArray.GetValue(i))));
}
return (rs);
is it better to create xsd file in VS2010 with only fill (all other implemtation i'll do on my own) property.
I added New Item, DataSet, over that i added tableadapter with stored procedure. i declared that it will do only the fill property(without returning the data). i want to implement all the other properties by demand in my way.
i wrote in the dal test.getRequestById1DataTable dt1 = new test.getRequestById1DataTable() how can i get the data and pass it between the layers?

C# - SqlDataAdapter.Fill(DataTable) Returns No Rows?
Feb 7, 2011I am trying to use a SqlDataAdapter to fill a DataTable, which I use as a data source to a DataGrid. The query is fine, at least when I run it manually in SSMSE. When I do the fill operation, the table gets the right columns, but no rows. The most frustrating part of this is that the code is identical (with a different query) on a different page. I cannot post the query, but my initialization code looks like this:
SqlCommand areaDAC = new SqlCommand (areaQuery, connection);
areaDAC.Parameters.Add (new SqlParameter ("@param", System.Data.SqlDbType.NVarChar, 50));
m_areaDataAdapter = new SqlDataAdapter (areaDAC);
Then to use it:
m_areaDataAdapter.SelectCommand.Parameters["@param"].Value = "Filter Val";
DataTable table = new DataTable ();
m_areaDataAdapter.Fill (table);
At this point, table has the right number of columns and no rows. I know the parameters are being added correctly, I know that data exists for the given query.

ADO.NET :: ExecuteNonQuery Using Stored Procedure Will Not Delete Record (SQLDataAdapter)
Sep 6, 2010I'm using VB.net 2.0 with a SQL server (2005) backend db. I've got a very odd problem. I'm trying to use a stored procedure with a parameter to delete a record from a table. I've tested the stored procedure by running it directly from visual studio and it works fine, but when running it through my application nothing happens. There's no error and it appears to have worked but the record is not deleted.
I've checked permissions on the backend db and giving the network ASPNet account the db owner role has no effect either.
Here's the code, there are 3 layers - the webform code, then the business logic class, then the dataconnection class.

SQL Server :: Timeout When Calling SqlDataAdapter.Fill (DataSet)?
Sep 13, 2010This issue has stumped me for a while. Hopefully someone here can give me some insight.
When my site runs the following code it works just fine 99% of the time.
[Code]....
The command is calling a SQL Server 2005 stored procedure that takes 20 parameters and returns 6 tables of about 5-50 rows each. The paramters are all NVARCHAR, INT, or BIT data types. Only one of the parameters is Input/Output. There is a total of about 100 rows returned. Normally this takes a fraction of a second, but for some queries, it times out after 30 seconds.
When I run the exact same query in the Management Studio query window it takes 1 second.
what I can do to get the same performance from .Net as I am getting from Management Studio?
DataSource Controls :: How To Add Rows To Datatable And Use Sqldataadapter Update Method

Excuse me but the most part of variable are in italian, however I think it is possible to understand how does it work. If I execute this code I obtain this error:

After this I added these lines of code just above the last line:
SqlCommandBuilder cb = new SqlCommandBuilder(adapter);
adapter.InsertCommand = cb.GetInsertCommand;
and I obtained this error:

DataSource Controls :: Stored Procedures & SqlDataAdapter Not Updating A Calendar Control?
Aug 24, 2010I have a database linked to a calendar. I had a peice of code that retrieved dates from a database and populated the calendar. I wanted to tidy up my code using stored procedures (they seem neater & i assume there's a benefit somewhere). so i came up with this, however it's not working. The calendar displays, but it's not being populated with the database entries. The SqlCommand & SqlParameter I have working elsewhere in my code; as with the SqlDataAdapter (which also worked before i tried to conver to a storedprocedure!) but combining these three (SqlCommand, SqlParameter & SqlDataAdapter) seem to be causing me problems.It's probably something stupid but if someone could take a look and point me in the right direction,

DataSource Controls :: SQLDataAdapter Postback / Create A Class, DataCommon, To Contain All SQL Data Manipulation Functions?
Apr 22, 2010I'm trying to create a class, DataCommon, to contain all my SQL Data manipulation functions. I've created a Subroutine called Init that initializes a SQLDataAdapter:
[Code]....
From my other classes I am creating an instance of DataCommon, calling Init, and calling another subroutine in DataCommon that pulls data from SQL and loads the data into my dataset. This part is working great -- no problems at all. I'm loading three different Datatables in the Dataset with no issues.
At this point, I'll perform my various manipulations on the datatables -- add/delete/modify rows -- again with no problems. All of this is creating postbacks...and this is where my problem begins. After I've done all my manipulations to the data and am ready to update my SQL tables, I have to re-initialize my SQLDataAdapter. I thought I could do something like:
[Code]....
But I get the error: Exception inserting Class. Thread was being aborted.
In my initial data load from SQL, each datatable is getting loaded from a single SQL table, so I was hoping to use the autogenerated Update/Insert/Delete statements by the SQLDataAdapter. As a test, as soon as I filled the dataset initially, I added a new row to one of the datatables and used the SQLDataAdapter.Update() method before a postback occurred, and it worked perfectly.
So, with all that being said, I guess my question is, how do I reconnect the table mappings between my SQLDataAdapter and dataset to autogenerate the updates after a postback occurs? I've tried researching this, but I get confused after reading about FillSchema vs TableMappings vs everything else I've read about.
