Hi All,
I'm trying to create a table that has one primary key with multiple foreign keys which reference different tables. The following is how I declared my table:
CREATE TABLE COURSE_SECTION
(
Csecid NUMBER(8),
Secnum NUMBER(2) NOT NULL,
Maxenrl NUMBER(4) NOT NULL,
Currenrl NUMBER(4) NOT NULL,
Cid NUMBER(6) NOT NULL,
Termid NUMBER(5) NOT NULL,
Day VARCHAR2(10),
Locid NUMBER(5),
Fid NUMBER(4),
primary Key (Csecid),
foreign Key (Cid) references COURSE(Cid),
foreign Key (Termid) references TERM(Termid),
foreign Key (Locid) references LOCATION(Locid),
foreign Key (Fid) references FACULTY(Fid)
);
I've receive the error message "unknown command beginning ........ - rest of line ignored" for many of the lines when I execute the above script in Oracle SQL Plus. I have tried many different things like rewording the lines or capitalize the letters of the attributes but my attempts were futile. Can you please point out what I have done wrong? Thank you in advance for your help.

Hi,
How can I create a foreign key column which is referencing the same tables another column. And if I have already created the table then how can I alter the table to enforce the same.
Any link or any sort of help will be very much usefull.

when we use OPENXML then we have to mention table structure like below one.
DECLARE @xml_text VARCHAR(4000), @i INT
/* put xml structure here */
EXEC sp_xml_preparedocument @i OUTPUT, @xml_text
SELECT au_id AS author_id,
au_lname AS last_name,
au_fname AS first_name,
a.title_id,
title,
royaltyper AS royalty
FROM
OPENXML(@i, '/root/authors/titles', 1)
WITH (
au_id VARCHAR(11),
au_lname VARCHAR(20) '../@au_lname',
au_fname VARCHAR(30) '../@au_fname',
title_id VARCHAR(15),
royaltyper INT) a
INNER JOIN titles b ON a.title_id = b.title_id
WITH (
au_id VARCHAR(11),
au_lname VARCHAR(20) '../@au_lname',
au_fname VARCHAR(30) '../@au_fname',
title_id VARCHAR(15),
royaltyper INT
)
suppose if i dont want to mention the table structure manually or hard coded rather dynamically fetch table structure,datatype and length then how could i proceed.
please help me with sample code.
thanks in advance

Hallo,
I have a database copy of a live database for development. On the live database is running a replication, but in the dev database it is not. However there are replication contraints and trigger in the dev database, and I can`t, for example, add columns to tables.
How can I delete all this replication artefacts?
Thank you for your help!

I have select query and I am getting results like
2
4
6
If I Pass 6 as Parameter then i need to get previous number of 6 i,e 4. If 9 then it has to give 0.
How can I write the query for this in Sql Server 2005
|
|
|
|
|
DECLARE
@ID INT
SET @ID = 4
SELECT TOP 1 ID
FROM tablename
WHERE ID < @ID
ORDER BY ID DESC
Test the result for null and replace with 0
OR
Put the results into a variable in the procedure and test the variable and return the results.
Never underestimate the power of human stupidity

Hello there...
I have a query which spends a lot of time calculating my CASE WHEN -statements.
There are around 16 CASE WHEN statements, which takes a huge time to calculate.
Is there any way to rewrite query?
My query looks like this
SELECT DISTINCT Product_Master.Product_Kid, Product_Master.Product_Name, convert nvarchar,Product_Master.Product_RegDate,103) as Product_RegDate, Product_Master.Product_RegDate as RegDate,
CASE WHEN (Product_Master.Product_Code = '' OR Product_Master.Product_Code IS NULL) THEN '-' ELSE Product_Master.Product_Code END AS Product_Code,
CASE WHEN (Product_Master.Product_ModelNo = '' OR Product_Master.Product_ModelNo IS NULL) THEN '-' ELSE Product_Master.Product_ModelNo END AS Product_ModelNo,
CASE WHEN (Product_Master.Product_Image = '' OR Product_Master.Product_Image IS NULL) THEN 'N' ELSE 'Y' END AS Product_Image,
CASE WHEN (Product_Master.Product_BrandId = '' OR Product_Master.Product_BrandId IS NULL) THEN 'N' ELSE 'Y' END AS Brand_Name FROM Product_Master ORDER BY RegDate DESC
|
|
|
|
|
case when (isnull(Product_Master.Product_Code, '') = '' then '-' else Product_Master.Product_Code end as Product_Code
In Word you can only store 2 bytes. That is why I use Writer.

Personally, I find it hard to believe that the CASE statements are what's taking time since they don't look complex. How do you know that the CASE statements are what take the most time? Have you tried the same query without some of the CASE statements, just returning the actual column data instead, and comparing the performance? Is the DISTINCT required? Is RegDate indexed?

Thanks for reply Scott,
Yes, I have tried the same query without CASE WHEN statements, and it works faster comperatively.
Moreover, The query is not this much only, there are many more CASE WHEN and Left Joins(which are necessary).
Left Joins are essential for the result, so I can't move it. The only options is to find alternate for CASE WHEN statements.

Then we'd probably have to see the whole query since the little we've seen doesn't indicate a problem. It would help to know the table structures and rough row counts.

Scott,
here is the whole query.
and roughly, records for each supplier is minimum 400(rows)
declare @a as char(1)
declare @b as varchar(35)
set @a='Y'
set @b='<span style=''color:Red''>N</span>'
SELECT DISTINCT
Product_Master.Product_Kid, Product_Master.Product_Name, convert(nvarchar,Product_Master.Product_RegDate,103) as Product_RegDate, Product_Master.Product_RegDate as RegDate,
Isnull(Product_Master.Product_Code,'-') AS Product_Code,

Left joins.....
yup that's costly

|
|

|

Yeah, what they say. Plus why convert (and transmit) the textual RegDate? Perform that outside the database.
|
|
|

I suppose that the nulls are there because of the left joins, you refer to in your answer to Scott, and therefore is nothing you can do anything about.
But how about the zero length strings, do they serve a purpose?
If not, you can add a check to the columns that disallows zero length strings at inserts and then you can remove that check in the query, which should speed it up a bit.
Alternatively swap to Oracle where you can use a Function Based Index which would speed up things immensely.
Like: Create index PM_PRODUCTCODE_EXIST_IDX ON PRODUCT_MASTER(Product_Kid,CASE WHEN (Product_Code = '' OR Product_Code IS NULL) THEN '-' ELSE Product_Master.Product_Code END);

I'm sorry I have no answer to your question. However, I don't know that you will get one seeing as how you violated #8 in the "How to get an answer to your question" sticky thread. :-P
8. Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.

Hello bapu2889, i agree to Matt U.
if you want to get fast and good answers, don't SHOUT.
To your problem.
You're calling a stored procedure which has 5 parameters (in). When you use more than one pair of names, your code creates a sqlcommand with 7 parameters, 9 parameters and so on.
When i try your code, i am getting an sqlexception because there are too many parameters. The exception you are getting is an conversion error in the catch-clause. Sorry, but i can't find this out because i haven't installed vb.net.
Try this:
Insert the location data (change your sp, return the id of the new location as out parameter).
Insert each of the userdata with the id of the new location (execute second sp in a loop, set parameters).

hello sir
thanks for ur rep.
and i dont know that i have shouted on any body
this is what i have done so far but no luck.
this is 2 different sp
ALTER PROCEDURE dbo.NewInsertCommand
(
@City nvarchar(50),
@State nvarchar(50)
)
AS
SET NOCOUNT ON;
DECLARE @LocationID int;
INSERT INTO [Location] (City,State)
VALUES (@City, @State)
SELECT @LocationID = SCOPE_IDENTITY()
this is the second one
ALTER PROCEDURE dbo.InsertUser
@FirstName varchar(25),
@LastName varchar(25),
@LocationID int
AS
INSERT INTO [UserData] (LocationID, FirstName, LastName)
(SELECT @LocationID, @FirstName, @LastName)
RETURN
and this is the vb
Private Sub AddNewNames()
FirstNameArray.Add(FirstName.Text)
FirstNameArray.ToArray()
LastNameArray.Add(LastName.Text)
LastNameArray.ToArray()
End Sub
Private Sub InsertData()
Try
Dim Flag As Boolean = False
'GetDBConnection()
Dim cmd As New SqlCommand("NewInsertCommand", LetsGo.GetDBConnection)
cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@City", SqlDbType.NVarChar).Value = ComboBox1.SelectedItem
cmd.Parameters.Add("@State", SqlDbType.NVarChar).Value = ComboBox2.SelectedItem
cmd.ExecuteNonQuery()
cmd = New SqlCommand("InsertUser", LetsGo.GetDBConnection)
cmd.CommandType = CommandType.StoredProcedure
For I As Integer = 0 To FirstNameArray.Count - 1
cmd.Parameters.Add("@FirstName", SqlDbType.NVarChar).Value = FirstNameArray(I).ToString
cmd.Parameters.Add("@LastName", SqlDbType.NVarChar).Value = LastNameArray(I).ToString
cmd.ExecuteNonQuery()
Next
MsgBox("Data Saved Successfully !", MsgBoxStyle.Information)
and one more thing i dont know how to get @LocationID from one sp to another sp as well
so would you mind to guide me please
waiting for your kind help
thanks
