Funny Network Behaviour
Jul 20, 2005
Hi,
In order to establish a security enhanced SQL server setup, I tried
to switch off network access by disabling all networking protocols,
so that the server can only be reached through a pipe. Nevertheless
the server was visible in the network and could be accessed from
all clients. Does anybody know what is going on here?

Ok a network tech put an executive assistants database on sql with the upsize wizard in access. Only problem is that she cant input anything into the database, my guess is that its due to no Primary key in the new sql table. I have had this problem before am I correct in my assumptions???

This sure looks like a bug, but I'm still new...
First I create a simple database:
SqlCeEngine eng = new SqlCeEngine(@"Data Source=My Documents est.sdf");
eng.CreateDatabase();
eng.Dispose();
Then I put something in it:
SqlCeConnection conn = new SqlCeConnection(@"Data Source=My Documents est.sdf");
SqlCeCommand cmd = new SqlCeCommand("CREATE TABLE myTable (ID int, name nchar(10))");
cmd.Connection=conn;
conn.Open();
cmd.ExecuteNonQuery();
cmd.CommandText="INSERT INTO myTable (ID, name) VALUES (1,'bill')";
cmd.ExecuteNonQuery();
Then I try to get the maximum value from the first column.
cmd.CommandText = "SELECT max(ID) FROM myTable";
int index = (int)cmd.ExecuteScalar();
At this point I get an InvalidCastException raised. Using the datareader to extract the value produces the same exception, however I can go through the Query Analyzer on the device and execute the query and it comes out fine...???
This has really got me confused. Any thoughts?

I am getting a new server online at a customer, and our system shows very funny erorrs under full load. No explanations could be found. Anyone has some?
Here we go:
Server failed to resume the transaction, desc: 360000054a. The transaction active in this session has been committed or aborted by another session.,
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
and
New request is not allowed to start because it should come with valid transaction descriptor.
System.Data.SqlClient.SqlException
I am a little lost on those. Simple fact is that I do not find any description of those. Anyone an idea what causes these?

Hello all,
We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Should have 330 rows if it works right.

Hi
While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears.
Does somebody knows why?
I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.
Thanks!!

I use sqlclient to connect directly from my mobile 5 pocketpc to a sql server 2005 database on my desktop.
I use a sqldatareader to traverse the results of a query that delivers 2 fields: (1) the filespec, and (2) the image field.
I use a filestream with a binary writer to write the contents of the image data to the pocketpc's storage card.
I have a test table with 10 images, not one more than 4 MB. I cannot complete a test run prior to receiving the general network error.
The pocketPC is connected via activesync to the desktop, and I connect to the database with:
Integrated Security=false;
user id=sa
password=admin.
Any help with this strange error would be greatly appreciated.

Hi, when I copy and paste results from query analyzer into Excel it appears that values with zeroes at the end loose the zeroes. Example, if I copy and paste V128.0 into an Excel cell it comes out as V128 or if I copy 178.70 it displays as 178.7 - any ideas? I'm using SQL Enterprise Manager for 2000.

This is the actual statement displayed from Response.Write in classic ASP. INSERT INTO WOTasks (WoNum,TaskNum,TaskDesc,TaskMemo,Account,ModifyDate,Estimate,TaskHours,Unit,UnitCost,TotalCost) SELECT '06-012497',TaskNum,TaskDesc,TaskMemo,Account,'2006-Oct-3',1,TaskHours,Unit,UnitCost,TotalCost FROM Tasks WHERE procnum = '000002' There are 4 records returned from the SELECT part of the statement. In some situations, 4 records are inserted to WOTasks table, in others, only 1 record is inserted. I can't find out why 1 record, instead of 4, record is inserted. A form page submits the form to the save page using post method. The above statement is contained in the save page. When one of the form textbox is filled, 1 record is inserted. When the textbox is not filled, 4 records are inserted. You may think the textbox has something to do with the behaviour. I also think so but the content of the textbox does not affect the sql statement. In both cases, the insert statement is the same. In the actual codes, only strings in quotes are variables and the rest are hardcoded. When I run the statement in SQL Server, 4 records are affected. No such problem when connected with Access.The actual code belowSub AddTask(ByVal proc, ByVal wonum) Dim sSQL sSQL = "INSERT INTO WOTasks (WoNum,TaskNum,TaskDesc,TaskMemo,Account,ModifyDate,Estimate,TaskHours,Unit,UnitCost,TotalCost) SELECT '" & wonum & _ "',TaskNum,TaskDesc,TaskMemo,Account,'" & curDate & "',1,TaskHours,Unit,UnitCost,TotalCost FROM Tasks WHERE procnum='" & proc & "'" 'Response.Write sSQL:Response.End conn.Execute sSQL, , 128 End Sub

Might be out to lunch, but I can't figure why this is being ordered the way it is:
SELECT '1' as t
UNION ALL
SELECT 'A' as t
union all
SELECT '['as t
ORDER BY t
I'd expect it to be 1, A, [ but instead it's [, 1, A [ is ascii 91 which is greater than both 1 and A, so why does it come first?

Can someone kindly guide me what should I look for in order to solve this.

When I run the command:
exec master..xp_cmdshell 'NET USE'
from the analyzer the box responds there are no entries in the list.
After that, I run the command:
exec master..xp_cmdshell 'NET USE Z: /DELETE'
after which the box responds with a "network connection could not be found."
and that's all okay.
The weird thing is:
exec master..xp_cmdshell 'NET USE Z: \MACHINESHARENAME'
results in a "The local device name is already in use.".
The machine in this particular case is the box itself. I have no problem accessing other disks on other systems. I can see the share using the view command. There's no maximum on the share itself and I can connect to the share using another sql box with the same user.
I don't know why it won't budge, worked before like a charm. After six months or so it just stopped. Anyone seen/solved this behaviour?
thanx,

Hi there,
I wonder if one of you worthy folks can help me out with some strange behaviour exhibited by a piece of SQL. Its my first post here , so please be gentle. :)
Here is my simple example :-
<my test table>
create table test
(ind int,
message varchar(255))
insert into test (ind, message) values
(1,'date=01/06/2006')
insert into test (ind, message) values
(1,'date=20/12/2005')
insert into test (ind, message) values
(2,'test')
The first query is
select * from test t1
where t1.ind in (select max(ind) from test t2
where t2.ind = t1.ind
and t2.message like 'date=%' )
fine.... 2 rows
second query
select * from test t1
where t1.ind =1
and convert(datetime, (SUBSTRING(Message, CHARINDEX('=',Message,0)+1, 10)),103) > getdate()
fine same 2 rows...
but If I try to combine the 2 clauses in
select * from test t1
where t1.ind in (select max(ind) from test t2
where t2.ind = t1.ind
and t2.message like 'date=%' )
and convert(datetime, (SUBSTRING(Message, CHARINDEX('=',Message,0)+1, 10)),103) > getdate()
I get a
Server: Msg 241, Level 16, State 1, Line 1
Syntax error converting datetime from character string.
Please can anyone help me on this?
thanks

We have an application that executes a few queries against an SQL Server 2005 (64-bit) database. Since there can be several instances of the application running at any given time, and parts of the logic must be serialized, we've been using sp_getapplock and sp_releaseapplock. This has all been working fine since RC1 on which the system was released. However, after installing SP2 about a week ago, we have been having problems. The serialized portion of the code almost always stall now.
To see what is happening we've been using both Management Studio and Profiler. We have two applications running, let's call them A and B. Both create a prepared statement which begin with a call to sp_getapplock and ends with sp_releaseapplock. In between some tables are queried and inserts may be made in others. The accessed tables are never used anywhere else but in the serialized code. This is what is happening:
Application A: Calls sp_getapplock.
Application A: Queries a table.
Application B: Calls sp_getapplock.
Application A: Inserts a row in a table.
Application A: Calls sp_releaseapplock.
Application B: Waits indefinitely (or at least more than 4 hours, after which we killed the spid).
Profiler cannot detect any deadlocks when this is happening. There are no blocking operations according to Management Studio. I can see the application lock having been set when I look at the spid for Application B in Management Studio.
Since this started to occur frequently after installing SP2 and had not been seen before, we are wondering if any changes has been made that could cause this behaviour? Has anyone else had problems using application locks, where a query would stall indefinitely waiting for the lock to be released? How then did you resolve it?
Any suggestions or ideas are welcome,
Thanks,
Lars

When I run the package from business solution environment, DBdate cast converts my date column (correctly) into a European date format dd/mm/yyyy and as such is inserted into sql server table.
When I run a package as a job, the same date in inserted into the database as mm/dd/yyyy.
So, if I have 3rd January 2007 in the source, in the first case i'll find 03/01/2007 in the database.
When I run the package as a job, I find 01/03/2007 in the db.
The problem comes when I run different select statements - the 01/03/2007 behaves as if 1st March 2007
How can I avoid inserting of American data format into the db?

I'm trying to use SetRange method on a table with multi-columns index, but I didn't get the result I was hoping for from the query.
Here is the DDL for the table
Code Block
CREATE TABLE [Products] (
[ProductId] INT IDENTITY(1,1) NOT NULL ,
[ArrivalDate] DATETIME ,
[Name] NVARCHAR(100) ,
[CategoryId] INT,
CONSTRAINT [PK_Products] PRIMARY KEY
(
[ProductId]
)
)
;
CREATE INDEX IDX_ProductArrival
ON [Products]
([ArrivalDate], [Name], [CategoryId])
;
--insert some sample data
Insert into [Products] ([ArrivalDate], name, categoryid) values ('2008-1-22 13:00:00', 'PC 1', 1);
Insert into [Products] ([ArrivalDate], name, categoryid) values ('2008-1-22 13:00:00', 'PC 2', 2);
Insert into [Products] ([ArrivalDate], name, categoryid) values ('2008-1-22 13:00:00', 'PC 3', 3);
And here is the code I'm using
Code Block
using System;
using System.Data.SqlServerCe;
using System.Data;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
using (SqlCeConnection conn = new SqlCeConnection(@"data source=d:mydb.sdf"))
{
conn.Open();
int counter = 0;
using (SqlCeCommand cmd = new SqlCeCommand("products", conn))
{
cmd.CommandType = CommandType.TableDirect;
cmd.IndexName = "IDX_ProductArrival";
object[] start = new object[3];
object[] end = new object[3];
start[0] = new DateTime(2008, 1, 22, 0, 0, 0);
start[1] = "PC 2";
start[2] = 2;
end[0] = new DateTime(2008, 1, 22, 23, 59, 59);
end[1] = "zzzzzzzzzzzzzzz";
end[2] = 3;
cmd.SetRange(
DbRangeOptions.InclusiveStart | DbRangeOptions.InclusiveEnd,
start, end);
using (SqlCeDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
counter++;
}
}
}
conn.Close();
Console.WriteLine("Row count {0}", counter); //should show row count 2 but shows row count 3 instead
}
Console.ReadKey();
}
}
}
I'm setting the starting range to a date and a product name (PC 2) but it seems that the datareader only see the first array member and completely ignore the product name and show all 3 data instead of 2.
Am I missing something here?
Thanks

We have this webiste which uses SQL express as database engine. Sometimes certain features of the website stop working. Like membership provider and other database related things. I have described the problem in more details here: http://forums.asp.net/t/1172253.aspx
In consice the problem is: One query with fixed inputs does not always return the same results, though the data has not changed, you restart the SQL express and the problem resolives!
I think thats a problem with SQL express, because when you restart SQL express everything starts working. Our database is kinda big. Like above 500 MB with up to 50 concurrent users. And our machine got a 3.2 CPU with 512 MB of ram. And our application is the only application runing there.
What do you think please?
