I don't play with Oracle much at the moment - but have you configured the tnsnames.ora file so that the Oracle driver knows how to link to the database?

For that you need a Database project which can be found under Other Project Types.

Hi, not an expert SQL programmer so apologies if this seems like a novice question...
Is there a way to pass multiple parameters to a select statement in an SQL stored procedure? For example:
Say you wish to select all addresses in a certain county, where the counties table is foreign-keyed to the Address table on ID. So you would write a stored proc to accept a single county ID, and select on that basis.
But say you want to pass in a range of counties, and select all addresses with a county ID in that range? It's easy to do in inline SQL, using the IN operator, so I could build a SQL string in my data access class and pass that for direct execution to the DB engine, but I'd rather stay away from that approach for obvious reasons.
The other option is to not select on county, pass all results to my .NET class, and filter the data using my list of selection values in code before passing the resultset to the client.
I think I'd prefer the latter approach but if it were possible I'd like to do the whole lot in SQL to enhance performance. It's an MS SQL 2000 database.
Does anyone out there know of a way to get around this?
All the dude ever wanted... was his rug back.

Hi,
You can do some thing like this.
Create Procedure <procname>
@CountyID varchar(100)
Begin
Exec ('Select * from CountyTable where countyId in ('+@CountyID+')')
End
Where @CountyID contains the comma separated list of countyId's
Hope this helps you.

I have a Database MDF file created in MSSQL 2000
and would like to convert the database file to match the
MSSQL 2005 version our company recently obtained in an upgrade.
I can connect with MSSQL 2005 to my MSSQL 2000 datbase without any problems.
However I would like the database file structure to be that of the MSSQL 2005 as I believe that would be beneficial to performance and to make use of all other features of 2005.
No.1 Can I perform this conversion.
No.2 Can this be done with MSSQL 2005 or do I need an external tool.
No.3 If an external tool is needed which one should I get ?
I would be grateful for any help.
Thank You.

I normally back up the database in 2000 and restore it in 2005.
You can also just detach the database from 2000 and attach it in 2005.

Hi,
I have 10 000 products, I have a page parameter in my aspx page. Lets say it is page=1, then I want it to bring back records 1 through 50. Then if it is page=2, then records 51 through 100 should be returned.
Is this possible in a SQL statement in SQL Server 2000?
Regards

If there is an identity column in the table that increments by 1 each time you could use the SQL BETWEEN statement like so:
SELECT * FROM table_name WHERE identity_column BETWEEN (page_num * 50 - 49) AND (page_num * 50)
That's if there is an identity column, hope it helps.
Ma se wat?

I have a problem substracting dates in Oracle. I tested the following:
Create a new table with a date field
Insert a register using sysdate
Then a select (sysdate - dateField) doesn't return 0 as expected. In the SQL Developer it returns an empty field.
How can I solve that?
Sometimes, maybe depending on the time difference, it works and returns a value (really, I need (sysdate - datefield) * 24*60*60
Regards,
Diego F.

To break the diff between 2 dates into days, hours, minutes, sec -- you can use the following:
select to_char( created, 'dd-mon-yyyy hh24:mi:ss' ),
trunc( sysdate-created ) "Dy",
trunc( mod( (sysdate-created)*24, 24 ) ) "Hr",
trunc( mod( (sysdate-created)*24*60, 60 ) ) "Mi",
trunc( mod( (sysdate-created)*24*60*60, 60 ) ) "Sec",
to_char( sysdate, 'dd-mon-yyyy hh24:mi:ss' ),
sysdate-created "Tdy",
(sysdate-created)*24 "Thr",
(sysdate-created)*24*60 "Tmi",
(sysdate-created)*24*60*60 "Tsec"
from all_users
where rownum < 50

Could you try that basic sample so I see what is the result?
First create that table:
CREATE TABLE TB_TEST
(
ID NUMBER(2, 0) NOT NULL,
DATEFIELD DATE
, CONSTRAINT TB_TEST_PK PRIMARY KEY
(
ID
)
)
Now, I insert a register:
insert into tb_test values (1, sysdate)
commit;
And then, the select query:
select (sysdate-datefield) from tb_test where id=1
What is the result?

I have 2 tables storing documents as IMAGE Type and version of document
what i want is when i open and save a document if the document is changed then i want to save the version in detail table. Is there any method to compare IMAGE data types in SQL SERVER..?

value() Method (xml Data Type)
Performs an XQuery against the XML and returns a value of SQL type. This method returns a scalar value.
You typically use this method to extract a value from an XML instance stored in an xml type column, parameter, or variable. In this way, you can specify SELECT queries that combine or compare XML data with data in non-XML columns.

Can someone help me understand the meaning of this query I found in a stored procedure in a SQL Server 2005 database?
SELECT @varMID = master_id
FROM tbl_link
WHERE email_address=(SELECT @@identity)
The part I don't understand is the WHERE clause:
1. What does it mean when an identifier is prefixed by TWO '@' chars instead of just one? ( There is no variable declaration for 'identity', BTW. )
2. Is it even a valid SQL statement that appears in the parenthesis, and if so, is it querying from tbl_link ?
Thank you very much for any help!

Hi
1. @@Identity is a valid sql statement - which returns the last-inserted identity value.
2. This is used after an insert statement if you insert a row to a table where a column is having an identity type.
For example:
Assume the table EmpDetails contains three columns EmpID, EmpName and EmpAge.
EmpID should be auto generated serial no.
So if you run the foll. statement:
INSERT INTO EmpDetails (EmpName,EmpAge)<br />
VALUES ('XYZ',55)<br />
<br />
SELECT @@IDENTITY AS 'Identity'
Displays identity value used in the new row.
Hope you got it.

after insert new record , you can get the new unique ID by this.
