Excuting distributed queries in parallel

Hi,

Is it possible to execute queries in parallel on multiple linked servers? I retrieve the checksum of a table on a linked servers like this:

SELECT * FROM OPENQUERY(Server1, 'SELECT CHECKSUM_AGG(BINARY_CHECKSUM(*) FROM Table1')

I need to do this on multiple linked servers at the same time - is this possible? I tried the following but my workstation executes the queries sequentially:

SELECT ("Query Server1"), ("Query Server2"), ("Query Server3"),..

Any suggestions?

TSQL statement execution is always serial in a batch or module. You can run the statements in parallel by doing one of the following:

1. Use on-demand SQL Agent jobs which contain TSQL task with each distributed query. You can then start each job in your TSQL code and wait for their completion

2. In SQL Server 2005, you can use service broker messaging infrastructure to activate multiple procs in parallel with each one executing a specific query

However, it is not clear if you are returning the results to client or processing on the server side itself. If you are returning the results to client then these techniques will not be efficient because you will have to dump the results into a table and then query it back. So you might as well run 3 different commands from the client code.

EXCEPTION_ACCESS_VIOLATION

I got this error when i try to insert a data in a table
with a Text Column in a distributed application (MSTDC
COM+ ASP), somebody have some one idea about this
error ? more descriptions from event viewer :
Error : 0 Severity : 19 State : 0
SqlDumpExceptionHandler: Process 61 generated fatal
exception
c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is
terminating this process.Check your SQL Server error log for the exact stack dump that goes with the
Access Violation (AV) message. Pull out the keywords from the first couple
of lines of the dump and search for them in the online Knowledge Base.
Also, use profiler to find out what the exact command is that results in
the AV and see if the same thing happens when you run that command from
Query Analyzer.
Are you on the latest service pack for SQL Server?

Excel renderer in RS2005-Sheet names

The Reporting group in our company uses SRS 2005 to generate most reports for
the Company. Many of these reports are distributed automatically to our
clients. An increasing number of these reports are distributed as Excel
spreadsheets. These Excel reports generally contain multiple worksheets.
For customer convenience, these worksheets should be named. The portion of
Report Services that writes the Excel files, is apparently not capable of
naming these worksheets with user specified names when there are multiple
worksheets. However when only one worksheet is present, it is named with the
title of the report. Is there a way to name the worksheets dynamically as the
report is generated? If not, is it possible to write a custom renderer to do
so, or to extend the excel renderer? I appreciate any code examples.
Thanks in advance.You might want to look into Software Artisan's Excel writer for Reporting
Services. It gives you more control over the Excel rendering.
