I want to get record count from below example.
I made two tables. One is club_info and another one is club_members.
And each table has data like following
[club_info]
club_id
club_name
:
[club_members]
mem_id
club_id
:
I want to get club_name and the member count for selected club_id and want to return the result as sqldatareader.
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

View 4 RepliesI have website database with a data table constently being "insert, select, count". This table has over a million record and is growing really fast.
Now I'm start worring about whether or not my sql server could handle the pressure. or maybe to have a million record is not a good practice at all.
The specs of my server is almost the best in the market. So I won't worry about the hardware.
Just wondering if ended up 3 million record in that table, will my queries and sql server itself still running smoothly?
Is there a function that will search a record in a Sql Table, I'm using VB.Net.

I have a table of products and it has a productID field and a setID field.
Products can be grouped together by making the groupID the same for the both of them.
I have only @productID parameter. My goal is to get a list of products minus this product and any other product that it is grouped with (ie..setID is the same).
Here is the query that I wrote because it has worked when excluding products from another table. I used the explicit GUID and still nothing.

I have to retreive all records from a table except 1 record. For example: I give example from default database in SQL ie "master" In "master" DB we have "spt_values" table. Now if I want to retreive all records from spt_values table except 1-1 record of type = A and type = B. To retreive all records its a simple query "Select * from spt_values where type in ('A','B')" -- this will returns 16 records. Now I want to retreive all record except 1-1 record left in each type, so it will return 14 records in result.

View 5 RepliesI've got a sp as below:
The functionality I want to achieve is that when isHomePageFeatured is checked then this record is set to 1 for that column and for all the other records in the table it is set to 0.
This is fine for update as I can use the property Id to compare against, but for the newly inserted record it doesn't yet have a propertyId so I wondered if using newID() to affect all other records would have the same affect.

View 14 RepliesI have the folloing sql server error from my ASP.NET website.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
This seems to be a network related issue. But on the same machine where IIS is running, I have another C# application running that is not experiencing this problem. This happens after the website has been running for a few weeks. Will this be because the database connections are opened but not closed properly?. I wrote a test web page where i just open connection but not close it and I got Time out error when connection pooling is maxed out. Is this memory issue? Memory that are allocated are not deallocated in timely fashion?..
Everything is working fine for a few weeks and after that I get the above network error.
I have a formview with an entityDataSource. I need to include columns from related fields. I have seen many demos, with AdventureWorksDB, that imply that you can do this by using INCLUDE in the entitydatasource declaration. I have tried made many attempts and it just does not seem to work as demonstrated. I have attached the errors below and the EDS. I have also attached a JPEG of the model I am working in. Three errors demonstrating 3 different attempts to include a related table:

the code declaration for error 1:
