Mar 12, 2010

I'm trying to do a very simple update in Access:

[Code]....

works fine by itself, and if I replace the subquery with the result of the subquery, for example:

[Code]....

it also works. What the heck?

Error - Method 'First' Can Only Be Used As A Final Query Operation

Mar 16, 2011

I have the following query:

Dim roommates = From p In dbroom.Residents _
Where p.room = queryStudent.First.r.id _
Where p.building = queryStudent.First.b.id _
Where p.year = year _
Where p.semester = term _
Select p.person_name

It currently returns no results. I was getting an error when attempting to bind this resultset (since it was empty) to a repeater in ASP.NET, so I attempted to escape it:

If roommates.Count() = 0 Then
Dim nomates As String = "No current roommates."
rptrRoommates.DataSource = nomates
rptrRoommates.DataBind()
Else
rptrRoommates.DataSource = roommates
rptrRoommates.DataBind()
End If

But I still get the same error:

The method 'First' can only be used as a final query operation. Consider using the method 'FirstOrDefault' in this instance instead.

Mar 7, 2010

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

DataSource Controls :: Programmatically Add An Updateable Formview With Linqdatasource?

Aug 7, 2010

I have a gridview on a page and based on the row selected I need to fill out a form view (dynamic data enabled) from a linqdatasource. On gridview_sleectedindexchanged I create the linqdatasource and set it as the datasource for the formview. It displays nicely but clicking update returns a "Could not determine a MetaTable" error for the datasource mapped.

THe goal is to create a single page that allows users to select a row then get the appropriate data, create an updateable formview so further edits can be done. Do not want to scaffold.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.

ADO.NET :: Ado And Access - Sum Query SELECT SUM() As Total

Dec 31, 2010

Need to do a summary report of two items, sales and commissions by sales person, by date range. There are only a handful of salespeople. I messed around with SELECT SUM() for a few hours last night. It works easily, up until you need to do a few table joins, to say join on employee id to pull in names. Then it starts getting pretty convoluted, fairly quickly. Question is, is there maybe an easier way of doing this in asp.net than through the sql? It is Access, so I don't think LINQ will work, right? Just wondering if there isn't a quick, easy way of doing this that I don't know about.

Access :: Using Results From A Sql Query In A Variable?

Oct 2, 2010

I've managed to use my MS Access database with repeaters and gridviews in my website. Basically, printing the result of a query directly to the website seems easy enough using something like this :

[Code]....

After quite a bit of googling this seems to be a common way to do this. My question then seems kinda silly.

I want to use some of the data from the query in for example a variable without sending the data to a repeater or gridview and so on. Say I just want the username and a password from a database and want to store the username in one variable and the password in another for further use in the code. What do I do?

Access :: How To Calculate A Logical Value In SQL Query

Jan 6, 2010

In MS Access I can write a query like this (where ClassA, ClassB, etc, are boolean fields):

SELECT [ClassA] Or [ClassB] Or [ClassF] AS HasPrints, EntrySummary.EntrantID, EntrySummary.CompID, EntrySummary.ClassA, EntrySummary.ClassB, EntrySummary.ClassC, EntrySummary.ClassD, EntrySummary.ClassE, EntrySummary.ClassF
FROM EntrySummary;

However that method of deriving a calculated HasPrints value is not acceptable in ASP.NET. How can I rewrite my query in a standard SQL query format?

Access :: OleDB Query Is Too Slow?

Jun 15, 2010

im using an access database with less than 50.000 records on a single table, no relations.

ive put the following code inside a two for cycles as per the respective variables (i, j) the connection is opened outside the outer cycle and closed after it, im holding the connection open to save up on open/close time and im using OleDB thinking it would be faster than ODBC. The ds fill operation takes nearly 3 seconds in debug mode, the total process will require almost 4 hours. How is it possible to speed it up?

Access :: Can Include VB Function In Query

Apr 19, 2010

I have an access MDB database of latitude and longitude coordinates (x,y). I also have a function in VB similar to:

Public Function Distance (x1,y1,x2,y2) as Double
'Some code here
Distance = 'distance between x1,y1 and x2,y2
End Function

What I want to do is create a query that will show all locations contained in the table that are within 10 miles of user unetered coordinates (where LAT and LON are columns in the table and VarX and VarY are user proivided: SELECT *, Distance([LAT],[LON],VarX,VarY) as Dist FROM TableName WHERE Dist < 10

Obviously this doesn't work but I want to know how to accomplish this end result. Basically, I want to return a query of all locations within 10 miles of VarX and VarY. How do I incororate the Distance function into my query?

If it's not possible, what is the best workaround to accomplish this?

Access :: Create A Query From Filters?

Jan 25, 2011

am a bit unsure of the best way to go about this. I have a form where data is entered, date ranges, usernames, passwords etc and when the button is pressed on the form it searches a database and returns values which match the values entered.I can't think of the most efficient way to do this, could anyone give some pointers on where to start?I thought perhaps of writing a query and then just putting in the variables which pick up the entered values and reading it all in as one big string something like:

SELECT * FROM DB WHERE ProductID = "DateTxtBox" & "NameTxtBox"

I haven't checked the syntax but this is just to give you a idea of what I am thinking.

Access :: 2007, Delete Query Does Not Work?

string sql = "DELETE * FROM participants WHERE participant_id = @participant_id"
OleDbCommand command = DataAccess.NewCommand(sql);

command.ExecuteNonQuery();

The really weird thing is that it will work if I hard code the value:
string sql = "DELETE * FROM participants WHERE participant_id = 1"

Access :: Insert Query Due To Database Relations

Jan 8, 2010

i have a problem executing an insert query. whenever i try to insert i have an exeption telling me it cant execute because a record needed in another table; where i select a value form that other table according a listbox, and then insert it into this table. here is a sample of my code:

OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|emp2.mdb");

int a = 0;
conn.Open();
string sqlcmd = "select id from nationality where descreption = '" + DropDownList1.Text + "'";
OleDbCommand readNatCmd = new OleDbCommand(sqlcmd, conn);
OleDbDataReader readerNat = readNatCmd.ExecuteReader();
while (readerNat.Read())
{
a = readerNat.GetInt32(0);
}
readerNat.Close();
conn.Close();
string saveEmpcmd = @"insert into employee " + "(nationality) " + "values (@nationality)";
OleDbCommand objCmd = new OleDbCommand(saveEmpcmd, conn);
objCmd.Parameters.AddWithValue("@nationality", a);
conn.Open();
objCmd.ExecuteNonQuery();
conn.Close();

now, the form executes with no errors, but it catches an exeption caused by the ExecuteNonQuery funtion; here it is in details:

System.Data.OleDb.OleDbException: You cannot add or change a record because a related record is required in table 'nationality'. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS

behavior, String method) at System.Data.OleDb.OleDbCommand.ExecuteNonQuery() at Default2.Button1_Click(Object sender, EventArgs e) in c:Documents and SettingsAdministratorMy DocumentsVisual Studio 2005WebSitesempDefault2.aspx.cs:line 305

when i remove the relation between the tables, the exeption isnt catched anymore, but the value stored in the employee table is 0 how can i solve this?
