I just happened to need this today, in MySQL though. There the function exists and is called ifnull. Works great. Thanks.

Situation:
One of the columns in the table is with xml data type.
Every seconds table has ~30 row inserted. After couple of mounts there will be ~ 30row x 60s x 60min x 24h x 30day = ~78x10^6 rows for 1 month.
The goal is: very quick retrieve data from that table, where some queries will target xml column (specific data in xml element or attribute).
Did anybody have experience with xml column in this way? Did this way of returning data is slow, or can be quick with using xml indexes, or even using xml indexes this way of returning data is still slow?

if i understand you correctly , you have a field in your table that is of XML data type and has some xml in it and you want to retrieve a certain attribute(Column) in that XML. Then my frinend , that means form the begining you made a poor design decision when designing a database, and to loop through the data will be tedious for sql to retrieve the amaount of data you want. use another way.Give us more info , mybe we can help in the Logic that you can follow.

I will try to explain, in one db I have 3 tables, because I want to return data as quick as possible to web services, I design 1 table with all necessary columns.
First design is without xml column, but number of rows will be at least 5x larger from design with xml column.
One of the solution is that I return data, and in web services to deal with xml column.
Second solution is that I return data filtered by xml attributes, or elements.
One more quick response is goal.

Hi,
I'd like to put all my database management in StoredProcedures or Functions, but I'm having a small problem:
1) I know I can't use INSERT, UPDATE or DELETE in UDFs, right?
2) So i created a SPROC that inserts a record to a simple table (id, name) and returns the ID in an output parameter. It's working fine.
3) I create a UDF that executes this SPROC and returns the ID... and here is my problem... looks like I can't execute my own SPROCs from a UDF. 
4) So.. how do I achieve this goal? Inserting a record and returning the auto generated id back to my web browser (asp.net application).
Here is some of my code:
CREATE PROCEDURE finsTeste
@snome varchar(50),
@nid int output
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO teste (nome) VALUES (@snome)
SELECT @nid = SCOPE_IDENTITY()
END
GO
CREATE FUNCTION insTeste
(
@snome varchar(50)
)
RETURNS int
AS
BEGIN
DECLARE @nid int
EXECUTE finsTeste @snome, @nid output
RETURN @nid;
END
GO
And then in the asp.net page I run a ExecuteScalar(StoredProcedure, "insTeste", params);
Thanks,
Dirso

Why do you need to create a UDF? You can get the value that you need directly from the SP.

I didn't know that... I thought I had to execute. Thank you very much! I just tried and it worked great!
Thanks,

hi
how to create foreign key in sql server 2005 using table designer
thanks
|
|

I'm assuming that you're using "Microsoft SQL Server Management Studio";
* Rightclick on the table, choose "design"
* Rightclick on any column in the newly opened window, choose "Relationships"
* Click "Add"

Hello everyone!
I wonder is it possible to create SQL querie using FULL JOIN in Access 2003? When i try it i just get syntax error. So does anyone have an idea how to simulate full join in access?
Cheers!

Which error message do you get? Post your code to see where is wrong.

There is no reason to simulate the Outer Join.
Please post your query along with the error you receive.

Possibly the union of a left join and a right join?

Yes I actually tried that and made it. IT is actually union of left join, right join and inner join

Hello,
I have two data tales in Access. One contais 2 million recors and the other contains 116000 records. The Customer name, street address, city and zip code fields need to be matched against each other across both tables in order to fin mismatches and exact matches.
Since one of the tales is very large, I am having a problem with the database program hanging every time I run the query. I tried doing this in SQL server 2005 as well, with no success.
Can anyone suggest a method for accomplishing this?
Regards.

You can create a non-clustered index for every condition and If you optimize your query that also will help you. Please post your query.

2 million records is not large in SQL server (although it may be in Access) so it has got to be your query. As suggested by others add some indexes and try optimising your query.
