Hi All,
I'm a relative newbie to SQL Server, so please forgive me if this is a
daft question...
When I set "Show Execution Plan" on in Query Analyzer, and execute a
(fairly complex) sproc, I note that a particular query is reported as
having a query cost of "71% relative to the batch" - however, this is
nowhere near the slowest executing query in the batch - other queries
which take over twice as long are reported as having costs in...

Does SQL Server have a query cache similar to mysql, whereas the query
result is cached, if the table has not been changed?
If so, please refer me to more info.
Thanks.

I have created the following test SQL code to illustrate a real
problem I have with some SQL code.
CREATE TABLE JCTable ( CustomerName varchar(50) )
ALTER TABLE JCTable ADD CustomerNo int
INSERT INTO JCTable ( CustomerName , CustomerNo ) VALUES ( 'Jon Combe'
, 1 )
INSERT INTO JCTable ( CustomerName , CustomerNo ) VALUES ( 'Bill
Gates' , 1 )
UPDATE JCTable SET CustomerNo = 2 WHERE CustomerName = 'Jon Combe'

I am trying to determine which of three stored procedure designs are
fastest in the Query Analyzer:
One query is a straight SELECT query with all desired rows and a dozen
(tblName.RowName = @param or @param = Null) filters in the WHERE
statement.
One query populates a #Temp table with the UniqueIDs from the results
of the SELECT query in the above example, then joins that #Temp table
to get the desired rows.

Hello,
Running a query for the first time on DB2 takes a fixed amount of time.
But when query is executed for the second time, the amount of time is
usually less since the query is (most probably) cached already.
I would like to clear out the DB2-UDB 8.2 query cache (I want the
previous execution time again).
Any advice would be appreciated.

Hi,
i am doing ajax requests to an IIS server. the response is a JSON
string, stored in xml.responseText. in IE everything is fine. in
firefox, only a part (80%) of the string is delievered in 8 out of 10
cases; sometimes it does work, but in most of the cases it does not.
both browsers receive the same response header from IIS:

I use the DES_ENCRYPT and DES_DECRYPT with the string 'sfG3853ncr1pt'
I can't seem to encrypt the number 227968199 because I tried several
times and also tried other numbers which work fine.
Here is a sample session:

I am starting to find more web pages that are using a query parameters
after the JavaScript file.
Example can be found at www.opensourcefood.com. Within the source
you'll see: <script src="/shared/scripts/common.js?revision=1.6"
type="text/javascript">.
I am trying to see if there is any big deal to this or a best practice
that is starting to creep up in the JavaScript community. If this is
used only as a way to distinguish what...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
