DataSource Controls :: A Table With Over A Million Record?

May 12, 2010

I 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?

DataSource Controls :: Exclude Record From The Same Table?

Jan 27, 2010

I'm not sure if I'm using the correct SQL for what I need. Well, I know that I am not because I'm not getting the results that I expect.

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.

DataSource Controls :: Select All Records Except 1 Record From A Table In SQL

Jun 7, 2010

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.

DataSource Controls :: Using NewId() To Identify Current Inserting Record And Affect All Other Records In Table?

Apr 27, 2010

I'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.

DataSource Controls :: Getting The PK ID Of The Newly Created Record After Inserting A New Record?

DataSource Controls :: Sql Server Network Related Error?

Jun 2, 2010

I 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.

DataSource Controls :: EntityDataSource With Include For Related Columns

Feb 28, 2011

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:

DataBinding: 'TmModel.tbICObjectBase' does not contain a property with the name 'Group'
the code declaration for error 1:
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Group") %>' />
DataBinding: 'TmModel.tbICObjectBase' does not contain a property with the name 'tbICTagBase'.
the code declaration for error 2:
<asp:Label ID="Label1" runat="server" Text='<%# Bind("tbICTagBase.Group") %>' />
DataBinding: 'System.Data.Objects.DataClasses.EntityCollection`1[[TmModel.tbICTagBase, TmModel, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' does not contain a property with the name 'Group'.
the code declaration for error 3:
<asp:Label ID="tbICTagBasesLabel" runat="server" Text='<%# Bind("tbICTagBases.Group") %>' />
EntityDataSource
<asp:EntityDataSource ID="entDSObjectBase" runat="server" AutoGenerateWhereClause="True"
ConnectionString="name=IntouchDBContainer" Include="tbICTagBases"
DefaultContainerName="IntouchDBContainer" EnableFlattening="False"
EntitySetName="tbICObjectBases" EnableDelete="True" EnableInsert="True"
EnableUpdate="True" EntityTypeFilter="tbICObjectBase">
<WhereParameters>
<asp:SessionParameter SessionField="Tag" Name="RecID" Type="Int64" />
</WhereParameters>
</asp:EntityDataSource>

You can see the model at [URL] Or [URL]
