Dynamic Order By!

Hi all, I am new to store procedures and am trying to write one with a
dynamic or..
Below is my feeble attempt if anyone can point me in the right direction
that would be great.
CREATE PROCEDURE get_event_list
@.order_column INT = null
@.order_mode = varchar(4)
AS
BEGIN
SELECT event_code,event_title,event_topic,event_category, event_id FROM
event
ORDER BY
//select a table column based on a numeric value in @.order_column
parameter
//Then determine orientation by value in @.order_mode
//If order_mode = "asc" then the query is to be order ASC and vica versa.
END
AJ
CREATE PROCEDURE get_event_list
(@.order_column INT = NULL,
@.order_mode VARCHAR(4))
AS
BEGIN
SELECT event_code, event_title, event_topic, event_category, event_id
FROM Event
ORDER BY
CASE WHEN @.order_mode='ASC'
AND @.order_column=1 THEN event_code END ASC,
CASE WHEN @.order_mode='ASC'
AND @.order_column=2 THEN event_title END ASC,
...
CASE WHEN @.order_mode='DESC'
AND @.order_column=1 THEN event_code END DESC,
CASE WHEN @.order_mode='DESC'
AND @.order_column=2 THEN event_title END DESC,
...
END

performance by including all the possible SELECTs in your SP, enclosing each
in an IF statement. If you prefer a single query solution then you can use
the CASE method I have given, or you could try using Dynamic SQL.

Here is some example I have. I know it is not a fancy solution, but it
is flexible...
CREATE PROCEDURE SomeList
@.akt CHAR(1) = '1',
@.OrderBy VARCHAR(50) = 'NazivUcionice',
@.OrderSort VARCHAR(10) = 'ASC'
AS
DECLARE @.SQLstmt varchar (1000)
SELECT @.SQLstmt =
'SELECT U.ID AS ElementID,
U.Naziv
U.Vrsta,
U.Tip,
U.Vlasnistvo,
U.Aktivna,
U.Broj_mjesta
FROM U
WHERE U.Aktivna=' +@.akt + '
ORDER BY ' + @.OrderBy + ' ' + @.OrderSort
EXEC (@.SQLstmt)
GO

How do I create views in MSSQL where the source is coming from an Oracle
table?
Thanks.

Dynamic field question

Can someone point me in the right direction to solve the following
(basic) SQL problem below using SQL Server:

Let's say I have a table like this that lists people's likes:

CREATE TABLE likes (
myname VARCHAR (60),
travel BIT,
eatingout BIT,
disco BIT,
swimming BIT);

Let's say I put the following data inside this table:

INSERT INTO likes VALUES ('Darren', 1,0,0,1)
INSERT INTO likes VALUES ('John',1,1,0,1)
INSERT INTO likes VALUES ('Peter',0,0,0,0)
INSERT INTO likes VALUES ('Jill',0,0,0,1)

Then what I want is to create a (view? Or function? I am not sure),
called likes_details' that when I send this query:

SELECT myname, likes FROM likes_details

Returns the following:

Myname likes
DarrenTraveling and swimming
JohnTraveling, eating out and swimming
PeterDone not like anything
JillSwimming only

Please! Can anyone help!!

Thank you in advance.Darren,

The mess-ed up short term workaround to your problem with the existing
schema is:

SELECT myName,
COALESCE( NULLIF (
CASE travel WHEN 1 THEN 'Travelling, '
ELSE SPACE(0) END +
CASE eatingout WHEN 1 THEN 'eating out, '
ELSE SPACE(0) END +
CASE disco WHEN 1 THEN 'disco, '
ELSE SPACE(0) END +
CASE swimming WHEN 1 THEN 'swimming, '
ELSE SPACE(0) END, SPACE(0)),
'Do not like anything')
FROM likes ;

Now, the real solution to your problem is that you need to overhaul your
schema, it has values as column names, under-normalized and thus unusable. A
good way of representing this information would be like:

CREATE TABLE Persons (
Person_id INT NOT NULL PRIMARY KEY,
PersonName VARCHAR(10) NOT NULL,
...);
CREATE TABLE Hobbies (
Hobby_id INT NOT NULL PRIMARY KEY,
HobbyDesc VARCHAR(20) NOT NULL,
...);
CREATE TABLE PersonHobbies(
Person_id INT NOT NULL
REFERENCES Persons(Person_id),
Hobby_id INT NOT NULL
REFERENCES Hobbies(Hobby_id)
PRIMARY KEY (Person_id, Hobby_id)) ;

The primary keys in the Persons table & Hobbies tables are assigned with the
assumption that there could be other relevant attributes associated with
these entities, otherwise using Name & Desc as keys are just fine. The data
for these tables, based on the information you provided could be like:

INSERT Persons SELECT 1, 'Darren' ;
INSERT Persons SELECT 2, 'John' ;
INSERT Persons SELECT 3, 'Peter' ;
INSERT Persons SELECT 4, 'Jill' ;
GO
INSERT Hobbies SELECT 1, 'travel' ;
INSERT Hobbies SELECT 2, 'eatingout' ;
INSERT Hobbies SELECT 3, 'disco' ;
INSERT Hobbies SELECT 4, 'swimming' ;
GO
INSERT PersonHobbies SELECT 1, 1 ;
INSERT PersonHobbies SELECT 1, 4 ;
INSERT PersonHobbies SELECT 2, 1 ;
INSERT PersonHobbies SELECT 2, 2 ;
INSERT PersonHobbies SELECT 2, 4 ;
INSERT PersonHobbies SELECT 4, 4 ;
GO

The above schema represents a m-to-m relationship between Persons and
Hobbies. It allows you to add persons and hobbies to the system without
having to alter the tables and facilitates efficient querying. Now, you can
have a SQL statement like:

SELECT p1.PersonName, h1.HobbyDesc, ...
FROM Persons p1
LEFT OUTER JOIN PersonHobbies ph1
ON p1.Person_id = ph1.Person_id
LEFT OUTER JOIN Hobbies h1
ON h1.Hobby_id = ph1.Hobby_id

Get the resultset to your client application & cross tab the data to the
format with comma, add words like "and" etc for the requirements for
display.

Dynamic disk

Does clustering supports dynamic disk mirroring with SAN? As cluster
has single point of failure of disk, we want to mirror the databases.
Any ideas would be appreciated.
Thanks
Clustering does not support dynamic disks.

|||As Rodney pointed out, Clustering does not support Windows Dynamic Disks.
SAN vendors may provide some LUN mirroring capabilities, but that is outside
the scope of SQL server.
