Hi,
I have one table like
sno name
--- ------
1 hai
2 hello
3 hai
4 hello
5 hello
6 bye
7 take care
from the above table i want to display only duplicate values like
sno name
---- ------
1 hai
2 hello
3 hai
4 hello
5 hello
how to display it ?

SELECT * FROM tableA WHERE name IN (SELECT name FROM tableA GROUP BY name HAVING Count(*) > 1)
Here Sub-Query retruns only those names which are present more than once and main Query returns all rows where the same is present.

I wish to know if there is any way to create a trigger that runs when a user makes some insert / update / delete action on a table of a database and then add the same values to a table that dwells in another separate database, both Sql-Server. How can I use the table in the external database? is it possible?
Thanks.

hi
It is possible,
just call the tablename like
databasename.dbo.tablename
k.ravi sankar
|
|
|
|
|
If the table is not owned by dbo then?

Yay, it worked nice!

does this mean both databases are not in one server. if so, you need to link both using sp_addlinkedserver check online help for syntax and usage.
once after linking you can access the tables like <server>.<database>.<owner>.<table>
if both databases are on same then
<database>.<owner>.<table>
I've used both (in queries/functions/procedures) exceipt in triggers

Hi,
I have a table in which I have four columns.
ID (primary Key)
FirstName,
LastName,
Email
I want to add another column as @@identity in this already existing
table.
How can I do that.
seema
|
|
|
|
|
If ID is an integer then you would do:
alter table MyTable alter column
ID integer identity(1,1) not null When you insert new records then you use @@identity to show the identity number that SQL-Server has allocated to your new record:
Insert into MyTable (FirstName, LastName, Email)
values ('Andy', 'Harman', 'Andy@AndysWorld.com')
Select @@IdentityYou can find out more about this in the SQL Server Books-Online.

Andy

Plase any help me to solve this problem.
Thanks & Regards

I've never seen this problem. I've happily inserted much larger amounts of text. You'll have to post your code. I'm guessing that somewhere or other you have something that is truncating the text at 255 chars and that is causing the problem rather than the database.

If Query Analyzer is only displaying 255 characters, that's because that's the maximum it asks for by default.
Go to Tools, Options, Results tab and increase Maximum characters per column.

Well thought of! I never thought that it might be what he was seeing in Query Analyzer. I just assumed his application was getting back less information that was being put in.

Hi,
I work on a project which convert a database access in mysql and I have a field
which has 9 Mb and when I try to convert this field in mysql I get the error:
Error:Unable to write to stream<br />
I put the mysql sintax:
set global max_allowed_packet=16777216
but it doesn't work.
Maybe I didn't put it right.
I put this command in my program.
Please help.
Thanks

Hi
I'm executing the following Xquery on SQLserver 2005.
select
policy_xml.query('/Policy/PolicyApplication/Inuserer/InsurerID'),
policy_xml.query('/Policy/PolicyApplication/Insurer/AccountIdentifier'),
policy_xml.query('/Policy/PolicyApplication/Insurer/Type'),
policy_xml.query('/Policy/PolicyApplication/Insurer/HolderName')
from policyTable
where
policy_xml.exist('/Policy/PolicyApplication/Insurer/PolicyOwner/EntityID[.="E_1"]') = 1
Its taking 50 Secs to search from 10000 records{without indexes}
The table has 3 columns sno,policy_id,policy_xml.
I have primary index on policy_id field and 1 secondary index(path index) on the table.
When I enable the index the query takes 380 secs.
The size of loan_xml column is about 110 Kb for each row. We need to keep the indexes for some more complex update Xqueries. Is there a way out to improve the performance of the XQuery we are using? Please let us also know the reasons of decrease in performance using indexes on the table. Do indexs have any issues related to XQuery performance?

i want to create hierarchical infragistics grid. anyone can u give me the idea about this?

If you've installed the grid, there are a number of tutorials associated with it. Plus, the Infagistics forums are a better place to ask for help.

Better watch out. I got voted down the other day for suggesting that the OP use the forums supplied by the third party vendor.

Hi,
I need to return column names only. My code works, but I am changing the initial column name to something more meaningful, like the ID field I changed to SKU like:
ID AS 'SKU'
Here is my code how I returned back only the column names:
' Create SQL statement
Dim strSQL = "SELECT ID AS 'SKU', ProductName AS 'Product Name' FROM bvc_Product;"
' Create instance of connection and command object
Dim conn As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim command As New SqlCommand(strSQL, conn)
Dim dr As SqlDataReader
Dim i As Integer
' Mark the command as a stored procedure
command.CommandType = CommandType.Text
' Execute the command
conn.Open()
dr = command.ExecuteReader(CommandBehavior.SchemaOnly)
For i = 0 To dr.FieldCount - 1
Response.Write("Column: " & dr.GetName(i).ToString() & "<br />")
Next
My problem is is that I need the result to return the original field name, and the new field name, in this case I need it to return ID and SKU, and ProductName and ProductName.
How do I do this?
Can someone please advise?
Regards
ma se

Hi
It is not possible to get actual column names if alias name is added. If you are passing SQL Statment from the code behind, you can write to split the query as array and extract using substring 'as' then you will get an actual column name. Make sure that you have added 'as' for every column. I think this is bit complicated.
Just try it out.
