Booleans, SqlServer, And VB

Feb 16, 2007

Hi,

The three above seem to form an evil combination. ;-)

For now, I use varchar(5) in my SqlServer 2000 db and fill it with "True" or "False", which VB understands as boolean values in my .aspx/.aspx.vb pages.

Is there no way of using Bit instead in SqlServer, or even 0/1, and easily bind it in VB? How do others do it? (I've only seen other people struggling with this, and not any solution).

I can't understand why a language such as VB cannot be allowed to understand both True/False, 1/0, and Y/N!

Muchos gracias in advance,

Pettrer

Help With Booleans With UPDATE Command.

Jul 26, 2007

Hello, I'm using a Gridview to display a list of servers. Each server has a column in a table called "Enabled." I want to create a button that is supposed to toggle the value called "Enabled." I am able to make the button either to set Enabled to true or false, but I don't know how to make it toggle. Here is the command:UpdateCommand="UPDATE [ServerStatus] SET [Enabled] = 1 WHERE [ServerName] = @ServerName" The button is a buttonfield in the gridview:<asp:ButtonField ButtonType="Button" CommandName="Update" HeaderText="Toggle" ShowHeader="True" Text="Toggle" /> Does anyone know the syntax, or a way to make the button set Enabled to true when it is false, and false when it is set to true?

Class Method Is Smoking Fast When Executed Outside Of SQLServer, Dog Slow As A CLR Function Is SQLServer - Anyone?

May 10, 2007

We have a static class that makes an HTTPWebRequest to get XML data from one of our vendors. We use this as input to a stored proc in SQLServer2005. When I compile this class and call it from a console application in visual studio it executes in milliseconds, everytime. When I compile it, create the assembly and clr function and execute it in SQLServer, it takes around 14 seconds to execute the first time, then on subsequent requests it is again really fast, until I wait for 10 seconds and re-execute, once again it is slow the first time and then fast on subsequent requests. We do not see this behavior when executing outside SQLServer. Makes me think that some sort of authentication is perhaps taking place the first time the function is run in SQLServer? I have no idea how to debug this further. Anyone seen this before or have any ideas?

Here is the class:

Code Snippet

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Predict.Services
{
public static class Foo
{
public static string GetIntradayQuote(string symbol)
{
string returnQuote = "";

HttpWebRequest request = (HttpWebRequest)(WebRequest.Create("http://data.predict.com/predictws/detailed_quote.html?syms=" + symbol + "&fields=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,28,30"));

request.Timeout = 1000;

HttpWebResponse response = (HttpWebResponse)(request.GetResponse());

StreamReader streamReader = new StreamReader(response.GetResponseStream());

returnQuote = streamReader.ReadToEnd();

streamReader.Close();
response.Close();

return returnQuote;
}
}
}

When I run call it from a console app it is fine.

I compile it into a dll and then create the assembly and function as follows:

Code Snippet

drop function fnTestGetIntradayQuoteXML_SJS

go

drop assembly TestGetIntradayQuoteXML_SJS

go

create ASSEMBLY TestGetIntradayQuoteXML_SJS from 'c:DataBackupsCLRLibrariesTestGetIntradayQuote_SJS.dll' WITH PERMISSION_SET = EXTERNAL_ACCESS

go

CREATE FUNCTION fnTestGetIntradayQuoteXML_SJS(@SymbolList nvarchar(max)) RETURNS nvarchar(max) AS EXTERNAL NAME TestGetIntradayQuoteXML_SJS.[Predict.Services.Foo].GetIntraDayQuote

go

declare @testing nvarchar(max)

set @testing = dbo.fnTestGetIntradayQuoteXML_SJS('goog')

print @testing

When I execute the function as above, again, really slow the first time, then fast on subsequent calls. Could there be something wrong with the code, or some headers that need to be set differently to operate from the CLR in SQLServer?

Regards,

Skipper.

Problem Unicode Data 0x2300 In SQLServer 2000 SQLServer 2005 Express

Sep 20, 2006

Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))

Insert Data
insert into testunicode (Bez)values('��')
with 2 Unicode characters
�� = 0x2300
�� = 0x2122

Selecting the data
select Bez from testunicode
I see
"?��"

�� = 0x2122 is ok but instead of 0x2300 there is 0x3f

When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'��')

and select again voila i see
"��"
Does anyone have an idea?

Thanks

Trying To 'load' A Copy Of A SQLServer 2000 Database To SQLServer 2005 Express

Apr 18, 2008

I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.

I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?

The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.

Thanks!!

Replacing Sqlserver 2000 With Sqlserver 2005 Express

Jun 14, 2006

I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.

Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.

If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:

server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"

DB name: name of db instance

port: 1433(default)

user and pass.

My attempts so far results in

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."

and

"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."

SQLSERVER 2005 X64 Linked Server To SQLSERVER 7.0

Jun 20, 2007

Hello people.

I am in the process of planning a server upgrade to sql2005 x64.

I created 2 linked servers: one to a SQL2000 sp4 server and one to a SQL7.0 SP3.

I have the following error when I query the linked servers.
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "Unspecified error".
OLE DB provider "SQLNCLI" for linked server "IVDM2K" returned message "The stored procedure required to complete this operation could not be found on the server. Please contact your system administrator.".
Msg 7311, Level 16, State 2, Line 1
Cannot obtain the schema rowset "DBSCHEMA_TABLES_INFO" for OLE DB provider "SQLNCLI" for linked server "IVDM2K". The provider supports the interface, but returns a failure code when it is used.

I am aware of KB 906954.
http://support.microsoft.com/default.aspx?scid=kb;en-us;906954

I applied the instcat.sql on the SQL2000SP4 server and my linked server issues for that one are gone.

However, I ran the instcat.sql script on the SQL7.0 sp3 server and the linked server is still giving me an issue.

Can someone help me find a solution to this?

Difference In SQLSERVER/sqlExpress And SQLSERVER

Jun 6, 2007

Hi,
I am new to SQL Server 2005. I tried connecting to my local machine by using my machine name as Server name and then tried running the following query:
SELECT * FROM SYS.Objects. It gives me following error:
Invalid object name 'sys.objects'.

Whereas, if I connect to my local machine using mahcinenameSQLEXPRESS, then the above mentioned query runs fine.

Why is this difference? What is the difference when I login in these 2 different ways.
Any help would be appreciated.

Thanks in advance.

Why SQLServer ?

Feb 24, 2006

I have a choice of working with either SQLServer or Oracle within my company. I need to advise them which way to go. I need to support a couple of hundred users in a mixed workload environment (OLTP, Batch & Reporting)
The O/S will be Windows 2003 Server. My understanding is that Oracle is the better database technically but SQLServer is cheaper and easier to integrate with other MS technologies. My company will most likely buy into whatever technology will deliver value for money but also be secure and be able to scale.
Any views gratefully received.

SQLServer 32-bit Vs 64-bit

Jan 3, 2007

We're starting to think about migrating a 2000 32-bit sql/server to 64-bit (probably 2005). Performance gains are tempting when it can easily be bought, almost a management mantra . I've been doing some reading about the pro's and con's, most of what I've found is pro, very little on the con.
My impression is that the 64-bit version(s) is faster in most case, if not all. It would seem that most of the performance improvement is gained by the heavier equipment and overcome memory limitations. Too me, it looks like the integration of hw/os/sql is made very tight on 64-bit, more than 32-bit, which might be the main reason for the improvements.

Call me skeptical but I'm looking for some more con's and a little less on the "great, fantastic, improved and hoorah" that I've been reading. Anyone out there returned to 32-bit after a 64-bit disaster?

Is It MS SQLServer Or Something Else?

Jul 23, 2005

I am using a tool called AppDetective to identify database servers andthen to scan them for vulnerabilities.I've just been handed a list of machines and have been asked todetermine which ones are actually MS SQLServer. (AppDetective saysthat all of the systems on the list have MS SQLServer).Does MS SQLServer make use of the same engine/port arrangements forits other applications such as MS Access?I've also heard that the engine (Jett?) is also used in some otherWindows components, which is why the AV systems had such problems withSlammer last year. Is this true?Thanks in advance
