SQL Server :: How To Union Two Queries Without Duplicates
Aug 27, 2010I have a sql query that returns 4 columns CustName CustId CustZip CustPhone
I have a second sql query that returns the following 5 columns
CustName CustId CustZip CustEmail CustAddress
Both queries, query different data tables in the database, but return columns that are common to
both.
How do I union the two queries(Assuming a union is needed)
Which will result in no duplicates and an end result being the following output:
CustName CustId CustZip CustPhone CustEmail CustAddress
As you can see we want to not have duplicate values on output. So something like the following
is not acceptable:

View 1 RepliesSQLcommand Serverside For Gridview?
Mar 17, 2010I have a gridview, where I have made autocode using the wizard. However I need a dynamic SQLcommand from server side. I have tried this code, but it doesn't work, it works if I use this code from HTML (setting the sqlcommand in the SQLDataSource. I have deleted the sqlcommand from the HTML and instead I have implemented the code in the page_load event:
Code:
Dim str As String = SqlDataSource1.SelectCommand = "SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType2) ORDER BY Beregning.bId DESC"
SqlDataSource1.SelectCommand = str But this code works, when I apply the SQLCommand in HTML:
Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:IsoPlusConnectionStringDrift %>" SelectCommand='SELECT DISTINCT Beregning.bId, Informationer.Dato,Beregning.bType, Informationer.pNavn, Informationer.pNr, Informationer.Beskr, Beregning.uId FROM Beregning CROSS JOIN Informationer WHERE (Beregning.UserId = @UserId) AND Beregning.uId = Informationer.uId AND (Beregning.bType=@berType) ORDER BY Beregning.bId DESC'>

How To Execute An INSERT Using SqlCommand
Jun 20, 2010I have another class that creates the connection (see refined class half way down page) and I believe it connects or at lest I do not hit any of the exceptions in run time.
I would now like to insert data into my database but nothing is updated.
I am trying to follow this example but it is for reading.
I did run "querystring" on the show SQL Pane and it does execute correctly. It inserts data properly as a new row.
string queryString =
"INSERT INTO UserData UserProfileID, ConfidenceLevel, LoveLevel, HappinessLevel) VALUES ('a051fc1b-4f51-485b-a07d-0f378528974e', 2, 2, 2);";

Benefits Of Using SqlCommand.ExecuteNonQuery?
Mar 29, 2010a) SqlCommand.ExecuteNonQuery is used for update, insert and delete operations.
Besides the fact that by using ExecuteNonQuery instead of ExecuteReader we automatically know there won't be any query results returned, are there some other benefits/reasons why ExecuteNonQuery should be used?
b) Similarly, if we want a database operation to return a single value, we should use ExecuteScalar instead of ExecuteNonquery ,where with the latter result would be returned via SqlParameter. Is there any particular reason why we should prefer ExecuteScalar over ExecuteNonQuery?
DataSource Controls :: Join Query Or Union?
Jun 30, 2010i have two queries they are:
query1:
select CustID,NoOfChits from tblCust1 where [Group]='A' and CustID='a001'
query2:
select count(TKCustID) as Taken from tblAuctionGroup where [Group]='A' and TKCustID='a001'
Results of 1st query was:
----------
CustID NoOfChits
a001 2
Results of 2nd query was:

But i want to like below:
--------------------------
CustID NoOfChits Taken

Define An Entity For Selecting Union Set And Intersection Set Applications?
Aug 27, 2010i have a SearchEntity (SE), which contains following propertes
[Code]....
What i want to do is to pass this entity to the services and return how many ppl has been selected, but i was a bit confused about how to solve the union and intersection issues among each parameters( ex.1) and SEs themselves(ex.2). for example the following scenarios,
1. what if i want to select ppl who ( age>20 and female ) or (who live in LA and (chose answer no.1 or answer no.2))
2. what if to select ppl who ((age <20 or age >60) and female and live in LA and chose answer no.1)
OR
((age <18) and male and live in LA and chose (answer no.1 or chose answer no.2))
OR
(age>65 and live in NY)
in brief, could anyone tell me how to re-design my SE entity so i can handle all the possible scenarios in terms of selecting union and intersection and subset issues?

Handling Timeouts In A Website SQLCommand Object And C#?
May 14, 2010I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ...
Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied
I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page.
The error is not consistent nor is the time the page has to stay idle in order for it to occur....
The current sql command object timeout is 30 secs and the website timeout is 30 minutes.
C# - Calling SqlCommand Execution Time Is Increasing?
Jul 9, 2010I've got a loop that executes the stored procedure in a loop with over 40,000 iterations, like so:
SqlCommand command = new SqlCommand("WriteDataToDB");
command.Connection = _connection;
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@SignalID", SqlDbType.Int).Value = Arg_Signal.SignalID;
command.Parameters.Add("@SignalStrength", SqlDbType.Float).Value = Arg_Signal.SignalSiggestion;
command.Parameters.Add("@Time", SqlDbType.BigInt).Value = Arg_Signal.TimeWasHit;
command.Parameters.Add("@Value", SqlDbType.Float).Value = Arg_Signal.ValueWasHit;
if (command.Connection.State != ConnectionState.Open)
{
command.Connection.Open();
}
command.ExecuteNonQuery();
This code is called from a loop where I intercept and time every 1000th iteration. The times I get are below:
[0]: "Started 0ms"
[1]: "1000 done 578.125ms"
[2]: "1000 done 921.875ms"
[3]: "1000 done 1328.125m"
[4]: "1000 done 1734.375ms"
[5]: "1000 done 1140.625ms"
