I've got this query UPDATE linkeddb...table SET field1 = 'Y' WHERE column1 = '1234' This takes 23 seconds to select and update one row But if I use openquery (which I don't want to) then it only takes half a second.
The reason I don't want to use openquery is so I can add parameters to my query securely and be safe from SQL injections. Does anyone know of any reason for it to be running so slowly?
I have a issue where I am trying to pull some records from an Access 2007 DB that has linked tables from a SQL 2005 Server. When I go to do this the browser IE8 just sits there and does nothing. THe little progress bar at the bottom moves about half way then that is it. It will sit there and show no errors or do anything. I have experience with connecting and manipulating Access and SQL server DB's but not through Access with linked tables from SQL Server. Here is test code below:

This does not produce an error or anything. The browser just sits there and sits there. Is there something I am missing?
I am trying to display this query result in an aspx page.
It is very slow in loading. Here is the query. The inner query inside the outer quesry is the problem.(Please see the underlined part in the query) - (If I remove that part it is very fast.)

top 500
--This column is the issue
,Governing_Class=( case when exists (select top 1 tqc.class_code from
t_quote_class tqc
inner join t_quote_class_premium tqcm on tqc.class_code =tqcm.
class_code
where tqc.appid=pi.appid and tqc.class_code not in('8742' ,'8810','7380')
order by tqcm.premium_amt desc

then ( select top 1 tqc.class_code from

I have the following query that uses a linked server that is on a different VLAN of our network:

It works fine in Query Analyzer but when I put it into Visual Web Developer 2008 Express as a SQL Data Source I get an error:
"OLE DB Provider 'MSDASQL' reported an error. Authentication failed."
The below SQL query is running extremely slow. Im using this query on other tables and its processing about 5 rows per second. The below version is running 1 row every 10 seconds when @SQLNew is executed.

In my database when I fire query it takes 40 secs on 1 crore data, similar when I use join with other table then it take more time. I have taken care non cluster index such thing. But still I want to optimize my query, what other thing I need to take like buffer, disk size etc. I am not sure on this area.
View 11 RepliesOne of my peer wrote a query based on multiple tables using joins. One of the table is in a different database The query was taking much time
1. Create an SP
2. Create a temp table and copy all records from the external db
3. Avoid using Left Join as much as possible and use Inner Join
4. Create and use indexes
5. Remove tables/columns that are not necessary
In this scenario, I would like to suggest to use Covering Index, but how can it be created for multiple tables and a temp table?
How to insert data from local SQL server to remote SQL server (without using linked server) like below?

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?

While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.
i need to execute stored procedure on linked server (create procedure on linked server). i had try with this:

SQL code is looking like this

UDBV68 is linked server... Now, when i execute procedure from asp.net i got error 'Incorrect syntax near 'GO'.', but sql server doesn't report error...
Dbcall has value = "EXECUTE ('Create Procedure SelectOne as Select * From FixitOnline.Os_node ',952) AT UDBV54; GO"
I want to transfer temporary table from one server to another linked server. I want to transfer it like how Bulk insert does. Right now I'm transferring row by row. It should do bulk transfer.

View 4 RepliesWe have a MOSS 2007 custom web part based on a user control that queries a database cluster. When the connection to the database is made, we regularly experience the error below and have had to create a work-around in the code to retry the connection. We have 3 environments - development, staging and production; the error only occurs in production. The difference in the production environment is it is a farm with 3 WFEs and a SQL cluster, where development and staging are single machine instances. All are MOSS 2007 & SQL Server 2008. We cannot find what is causing this issue and I'm hoping someone else has experienced a similar problem and knows the cause.
This is the error that occurs frequently when the query is executed:
System.Data.SqlClient.SqlException: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)

More than one method will generate this, but this is typical code, note the retry work-around:
public static DataTable OurMethod(string someParam) {
const string query = "sp_OurStoredProcedure";
var resultsTable = new DataTable();
var connection = new SqlConnection { ConnectionString = OurDatabaseConnection };
var command = new SqlCommand(query, connection) { CommandType = CommandType.StoredProcedure };
var dataAdapter = new SqlDataAdapter(command);
var retry = 5; SqlConnection.ClearPool(connection);
while (retry > 0) { try { command.Parameters.Clear();
command.Parameters.AddWithValue("@someParam", someParam);
connection.Open(); dataAdapter.Fill(resultsTable); retry = -1;
} catch (Exception ex) { retry--; if (retry <= 0) {
LogError("Exception: DataAccess:OurMethod: *RETRIES EXCEEDED* " + ex, "error");
} else { SqlConnection.ClearPool(connection);
LogError("Exception: DataAccess:OurMethod: ATTEMPTS REMAINING " + retry + ". " + ex, "warning");
} } finally { dataAdapter.Dispose(); command.Dispose(); connection.Dispose();
} } return resultsTable; }
I have developed a web application in asp.net with C# in visual Studio 2005. And i used sql server 2008 as back end. When i run the program, it shows the following error..An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
