No problem.

i created a job to transfer data in one table to another table, it's working perfectly, but the problem is when data is transfering because of primary key vales it gives an error(primary key duplication), how can i insert data without getting an error
one possible thing is dalete every thing in the second table and then insert every thing in the first table to the 2nd.but i don't think that this is a good solution , i'm expecting a better solution.

If you want to update table2 from the matchuing records in table 1 and then insert any new ones
Update table2
set col1 = a.col1,.....
from table2 b, table1 a
where b.primarykeycol = a.primarykeycol
insert into table2
select col1,col2.... from table1 a
where not exists (select 1 from table2 b where b.primarykeycol = a.primarykeycol)
If you don't want to update table2 ignore the update.

thanx, but there is another problem, the two tables are in two servers ,assume-> table1 is in server A (sql 2000) and the table 2 in server B (sql 2005), so i want to do the transfer from server A to server B . i tried it with
insert into table_B (eid,ename,eaddr)
select r.eid,r.ename,r.eaddr
from [server A ip]\[sql instance]\[db]\table_A r
but get an error at the srver ip

You need to investigate LINKEDSERVERS. The alternative is to bcp the data out of table1 and into table2, but I guess you don't want to go that way.

How did you write the job in the first place?. I havent had much luck writing code to transfer data from a server to server. But if you have that ability then I can help with avoiding primary key duplication

i tried on the net and in MS site for this script, but the script was removed , can anyone tell me where i can find the script
|

tanx, i so it but i didn't try because i was desinged to sql 2000, at the moment i'm in the middle of my testing project i don't know if this is the same one which came with sql 2005.

As far as I am aware (however I could be wrong), SQL Server 2005 did not come bundled with the Northwind Database, nor has the actual Database changed since SQL Server 2000. I tend to just run the script on my 2005 instance, and it works fine with all sample code.
If you have any troubles using it, feel free to ask.

I am not too good with T-SQL...
I have a Temp Table with the following data:
Date Line WGT .... Form
XXX 1 126 .... ABC
XXX 1 124 .... ABC
XXX 1 126 .... EFG
XXX 2 126 .... ABC
XXX 2 123 .... EFG
XXX 8 124 .... EFG
XXX 8 126 .... EFG
XXX 8 127 .... HIJ
XXX 8 126 .... HIJ
...
I need to query this table as follows:
Select the Rows for Each 'Line' that have the lowest 'WGT' where the FORM value is distinct for that 'LINE'.
Does That make sense?
Output should be like:
DATE LINE WGT .... FORM
XXX 1 124 .... ABC
XXX 1 126 .... EFG
XXX 2 126 .... ABC
XXX 2 123 .... EFG
XXX 8 124 .... EFG
XXX 8 126 .... HIJ
...
I have tried every variation of distinct, min and group by that I can think of. I am thinking of resorting to UDF's but I know deep down in my inner Geek that this is simple. Any tips before I bore apall you with my pathetic T-SQL?

Not too hard, the basic principal is to create a query that gets the distinct line/form along with the min wgt and then join this back to the main table to get the final results.
My table was named "test" and I got the results you expect with this query:
select test.date,test.line,test.wgt,test.form
from test
inner join
(
select line,form,min(wgt) as minWgt
from test
group by line,form
) groupedTest
on test.line = groupedTest.line
and test.form = groupedtest.form
and test.wgt = groupedtest.minWgt

Excellent - just what I needed to point me in the right direction.
My actual query is much more complicated that the outline I gave, but I was able to expand your sample to complete the job.
Many thanks

All,
I have created LinkedServer and try to run a query. it is throwing error like
"
OLE DB provider "SQLNCLI" for linked server "SRCSVR" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "SRCSVR" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 53, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [53].
"
My SP_AddLinedServer is
"
exec sp_addlinkedserver
@server='SRCSVR',
@srvproduct= '',
@provider='SQLOLEDB',
@datasrc='SERVER=MyServer;UID=user;PWD=pass'
"
I tried to execute this Query
select Name from SRCSVR.DBNAme.dbo.TableName
I have enabled
Firewall
tcp/ip
Named Pipes
But still it comes.
Please let me help to overcome this problem.
Thanks

Is the server you're trying to connect to, default instance. If not try adding instance name after server name (if i remember correctly, @datasrc='SERVER=MyServer\InstanceName;UID=user;PWD=pass')

Hi all,
I have a .sql script file and wanted to use the following code to write it into one of the database. How should I configure the connection string? I'm new to database programming.
using System.Data.SqlClient;
using System.IO;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True";
FileInfo file = new FileInfo("C:\\myscript.sql");
string script = file.OpenText().ReadToEnd();
SqlConnection conn = new SqlConnection(sqlConnectionString);
Server server = new Server(new ServerConnection(conn));
server.ConnectionContext.ExecuteNonQuery(script);
}
}
}

I used the following string:
"Driver={SQL Native Client};Server=MACHINE_NAME\\SQLEXPRESS ;Database=C:\\tset.mdf;";
but ended up with exception saying "Driver" is an unsupported keyword and when I removed this keyword the unhandled exception occurred.

You should use the one SqlConnection (.NET) section

I am trying to compute the difference between two double precision columns, start_time and stop_time. I used this select statement:
Select (stop_time - start_time) AS Duration
From table;
The result I get back is a column name Duration with empty cells. What should be the correct syntax? Thanks.
|
|
|
|
|
What are datatypes of columns stop_time and start_time ?
I Love T-SQL
"Don't torture yourself,let the life to do it for you."
If my post helps you kindly save my time by voting my post.
|
|
|
|
|
the columns are of type double.
|
|
|
|
|
Could it be that either stop_time or start_time is NULL. In that case the result would be NULL.

i am having some trouble with a correlated-subselect-statement (using mysql 5.0):
i have a table that looks simplyfied like this:
myTable:
--------------------------
ColID NameID ColDate
--------------------------
1 1 2008-10-01
2 1 2008-07-01
3 2 2008-06-11
4 3 2008-09-12
5 4 2008-03-15
6 2 2008-11-21
7 3 2008-08-19
8 4 2008-01-30
--------------------------
now i need for every nameID to select only the row with the latest date.
desired result:
--------------------------
ColID NameID ColDate
--------------------------
1 1 2008-10-01
4 3 2008-09-12
5 4 2008-03-15
6 2 2008-11-21
--------------------------
i tried the following select-statement:
SELECT * FROM myTable AS T1 WHERE ColDate=(SELECT MAX(T2.ColDate) FROM myTable AS T2 WHERE T1.NameID=T2.NameID)
but got the error message: #1064 - You have an error in your SQL syntax.
thanks for any help with this.
