DataTable datatable1 = sqldatasourceenumerator1.GetDataSources();
foreach (DataRow row in datatable1.Rows)
{
Console.WriteLine("****************************************");
Console.WriteLine("Server Name:"+row["ServerName"]);

I'm not quite sure what you mean as the System.Data.Sql libraries ship with the .NET runtime. Have you attached the relivent System.Data components into your project using the 'Add Namespaces' menu?

Hi everyone,
I am working in a company where data is changed daily (it is a shopping center) where item prices change everyday, quantity in stock vary daily,...
What is the scenarios available for the back up on SQL Server 2000 (I am a developer not a database administrator, but I have a task to do which is to make a back up for the critical data) .
could u help me with some links or idea.
I was thinking of doing a full back up one time everyweek and daily I will do a differential backup?
I can't do a full back up daily because data is more than 20 GB and also some tables in the SQL database hold data that is very critical and (I want to include these tables in the backup) other tables holds data not important (I don't want to include these tables in the backup).
is that the best solution.
Thanks.

I'm not a DBA, but Yes, a weekly full backup with differential daily backup is a good start. Also look into log backups maybe every hour or so. In order to do partial database backups, I think the db has to be structured into filegroups; you then can choose not to backup certain filegroups.
Also, some of the commercial backup software out there have suggestions for SQL backup.

Hi
I'm trying to write some data to an SQL table. I'm using MSDE.
The SQL table has mostly real (4byte) columns.
according to CLS Single.NaN is a leagle type.
For some reason I can't insert NaN values to the table records.
I'm using DataSets for the transfer and working with C#, Visual2003.
Yes, I DO need to save and restore both numbers and NaN values.
And yes, I know there are tons of work-arounds to simulate this but I really need to do this simple task.
Anyone ?

I have two tables that I am trying to read using OleDB (tableA and tableB) the primary keys for tableA are: col1, col2, col3. tableB has col1, col2, col3, col4, and col5 where col1, col2, and col3 are foreign keys. Because of large number I instances I cannot read all the instances at once. The reason is that I get cache Exception error and Db2 admin does not want to increase the size of db2 cache. I used two nested loops in order to create and execute following sql statements
String SQLSt = "SELECT tableA.col2, tableA.col3, tableA.col4, tableB.col2, tableB.col3, tableB.col4, tableB.col5, TableB.Col6
From tableA inner join tableB
On (tableA.col1 = tableB.col1 and tableA.col2 = tableB.col2 and tableA.col3=tableB.col3 AND tableA.col4 = tableB.col4) where tableA.col1 = 55 order by tableA.col2, tableA.col3, tableA.col4, tableb.col5, TableB.col6 FETCH FIRST " + 2000 + " ROW ONLY";
I use the above statement outside of the loop to read the first 2000 record.
I used following statement in a outer loop to read the following records in chunk of 2000.
SQlSt = "SELECT tableA.col2, tableA.col3, tableA.col4, tableB.col2, tableB.col3, tableB.col4, tableB.col5, TableB.col6
From tableA inner Join tableB
On (tableA.col1 = tableB.col1 and tableA.col2 = tableb.col2 and tableA.col3=tableB.col3 AND tableA.col4 = tableB.col4) where tableA.col1 = 55 and tableA.col2 >= previous_value and tableA.col3 >= previous_value and tableA.col4 >= previous_value and tableb.col5 = previous_value And TableB.col6 >= Previous_value
order by tableA.col2, tableA.col3, tableA.col4, tableB.col5, TableB.col6 FETCH FIRST " + 2000 + " ROW ONLY”;
The inner loop would read one record at a time and store the information in a memory cache.
The number of records that is read is much less than actual records for instances where col1 = 55. That is there are 45000 records and I read only 29000. If I do FECH FIRST 100 row only
Then I get about 20000 records.
1. Is there a way that I can specify in the sql statement to read record I to record I+2000?
I would appreciate any solution to this problem.
Thanks
The Ole command is:
OleDbCommand cmdIndx = new OleDbCommand();
cmdIndx.Connection = new OleDbConnection( ConfigurationSettings.AppSettings["DBConn"]);
OleDbDataReader rdrIndx;
cmdIndx.CommandText = strSQL;
cmdIndx.Connection.Open();
rdrIndx = cmdIndx.ExecuteReader();
rdrIndx.Read()

Hi there,
I've got the following two tables:
<br />
CREATE TABLE [dbo].[Countries] (<br />
[ID] [int] IDENTITY (1, 1) NOT NULL <br />
) ON [PRIMARY]<br />
GO<br />
ALTER TABLE [dbo].[Countries] WITH NOCHECK ADD <br />
CONSTRAINT [PK_Countries] PRIMARY KEY CLUSTERED <br />
(<br />
[ID]<br />
) ON [PRIMARY] <br />
and...
<br />
CREATE TABLE [dbo].[Cities] (<br />
[ID] [int] IDENTITY (1, 1) NOT NULL ,<br />
[CountryID] [int] NOT NULL <br />
) ON [PRIMARY]<br />
GO<br />
<br />
ALTER TABLE [dbo].[Cities] WITH NOCHECK ADD <br />
CONSTRAINT [PK_Cities] PRIMARY KEY CLUSTERED <br />
(<br />
[ID]<br />
) ON [PRIMARY] <br />
Now I'd like to establish a one to many relationship between them. I guess I know how to do that in the enterprise manager. My questions are as follows:
If I have a relationship between those tables:
- how will I go upon deleting a country record? do I necessarily have to do that within a transaction?
- shall I use the "Force relationship for INSERT and UPDATE(s)?" (roughly translated from the enterprise manager)
- shall I use the CASCADE options?
- and, If I use those options, how will they affect inserting, updating and deleting.
I know that my questions might be a bit vague. I've been trying to google for a primer on this but couldn't come up with something really helpful. I'd appreciated anyone shedding some light here. Thanks in advance!

I can't answer this one  .
matthias s. wrote: shall I use the "Force relationship for INSERT and UPDATE(s)?" (roughly translated from the enterprise manager)
Well, you need a country to exist or not? if you do need the country to exist then...
matthias s. wrote: shall I use the CASCADE options?
Most certainly, countries won't be disappearing anytime soon (I hope  ) but in terms of programming, how important is it that you delete 50 cities if you try to delete a country? I think it's probably more important that you keep those cities. Imagine 400 records related to those cities being deleted as well .
matthias s. wrote: and, If I use those options, how will they affect inserting, updating and deleting.
Well, using enforcement of relationship will ensure inserts and updates have valid values for countryID. Deleting a country can have a serious impact on the infromation, as I stated above, is it ok for you to delete 50 cities because you delete a country? is that a good idea? you need to ask that yourself.
I think it's good practice to define relationships (the most important being enforce relationship for inserts and updates) because this makes programming easier. Cascade Delete... be very careful with this one, think if it's appropiate or not to remove information with this. Cascade Update doesn't affect much, specially if you use identity fields or GUID keys, you won't be needing this.
I just hope I don't make it more confusing  .

Hello everyone, i have a very strange problem when i using the full-text searching engin provided by SQL Server to search the web site.
If the keyword is directly after the tag , then there will be no matched result return. But if i change the to , then the correct result will be returned by the server. I spent whole day to solve this problem, but still get nothing.
Why this happend?
Thanks a lot!!

Hallo
I have 3 Tables
<br />
1st table with idfrist - descriptionfirst<br />
2nd table with idsecond - descriptionfirst<br />
3rd table with id - idfirst - idsecond - value<br />
Now i'd like to built a transformed tabel:
colheader with all items from idfirst
rowheader with all item from idsecond
values as sum from 3rd tables value (cols are( tofirst - tosecond - value)
The transformation works fine for all values entered.
But if one col from the colheader isn't used in the 3rd table,
there is no output column for this field defined in the first table ?!?
here si what is already have done with 2 tables
<br />
TRANSFORM Sum(third.value) three<br />
SELECT second.tofirst<br />
FROM third RIGHT JOIN second ON third.idsecond = second.tosecond<br />
WHERE (((third.tofirst) Like "*"))<br />
GROUP BY third.tofirst<br />
PIVOT second.idsecond;<br />
thx for helping

Hi, take a look at ADO.NET 2.0. In .NET 2.0 it is much easier to get schemas.

I am using MSDE on my computer. I have application that uses SQL. The application and MSDE are on the same computer. My connecting string follows:
this.cnKennel.ConnectionString = "Data Source=(local)\\NetSDK;packet size=4096;integrated security=SSPI" + ";persist security info=False;initial catalog=kennel";
Because I will be installing this application on many computers I would like not to specify the computer name/server name. Can someone tell me how I can do this.
|
|
|
|
|
I guess I don't clearly understand the question.
If the MSDE will always be on the same computer as the application, then your current connection string will always work (provided MSDE installed with the instance name NetSDK).If MSDE is installed without an instancename, then just DataSource = (local) will always work on the same box.
If the MSDE will be on only one of many computers, then you have no choice but to specify the name of the server (or its IP address if using TCPIP network library) and the instance name (if installed as an instance).
If there will be multiple clients, you likely should read the server name part of the connection string from a configuration file for your app, so it can be changed without recompling.
