there is no intersect in SQL Server 2000
select * from tableA where colA not in (select colA from tableB)
this returns all rows from tableA which has no corresponding row matching for colA in tableB

There are only 3 set operators i.e. union, except, crossjoin!!
However if you want the intersection to be done you could either use where exists , not exists or inner joins
examples:
SELECT DISTINCT city
FROM authors
WHERE EXISTS
(SELECT *
FROM publishers
WHERE authors.city = publishers.city)
SELECT DISTINCT authors.city
FROM authors INNER JOIN publishers
ON authors.city = publishers.city
SELECT DISTINCT city
FROM authors
WHERE NOT EXISTS
(SELECT *
FROM publishers
WHERE authors.city = publishers.city)

Hi
I have little doubt on your question. Do you want to intersect those two tables based on the column ID ??
If Table1 has {1,2,2,3} and Table 2 {2,2,3,4} then you want {2,3,4} display values from two tables.

Hi Parasu,
Your solution is here:
<br />
SELECT TABLEA.* FROM TABLEA<br />
WHERE EXISTS<br />
(SELECT * FROM TABLEB WHERE TABLEA.ID = TABLEB.ID)<br />
UNION <br />
SELECT TABLEB.* FROM TABLEB<br />
WHERE EXISTS <br />
(SELECT * FROM TABLEA WHERE TABLEA.ID = TABLEB.ID)<br />
Please note the difference here:
UNION
This removes duplicate results
UNION ALL
Incorporates all rows into the results, including duplicates. If not specified, duplicate rows are removed.
Hope this solves your problem

Select * from tablea,tableb where tablea.columnname=tableb.columnname.
Generally Intersection means having data inboth the tables should be displayed.
For this we have to put a column in both tables which contains same data
So, Select * from two tables where columnin tablea=column in tableb are equal

Is it possible to run a .sql file on sql server through .net code?

Yes.
However, remember that GO is not part of SQL. It is a preprocessor commant to the Query Analyser that tells it where to split the Script into individual batches. You must make the same splits when issuing the SQL via the SqlCommand.
I blogged in more detail about this here[^] - It will show you how to handle the situation with GOs too.

For this I need to store the file contents in string and pass it to commandText

Yes, my previous answer shows you how to do that. Please look at the source code to the application to see how that is done.

system.data.sqlclient
transaction can be maintained by simple way of begin transaction and thereby commit transaction or rollback the transaction.
If not you can use the concurrency levels too!!!

The difference between One-to-One and One-to-Many is mostly conceptual. A query for either will be exactly the same. However, it can be enforced using a combination of a Foreign Key constraint and a Unique constraint. What this will do is enforce the relationship for UPDATE, INSERT and DELETE, but again, not SELECT.
If your schema looks like this:
<br />
CREATE TABLE Table1 (<br />
[ID] INT,<br />
BLAH,<br />
BLAH2<br />
)<br />
<br />
CREATE TABLE Table2 (<br />
[ID] INT,<br />
Table1ID INT,<br />
BLAH,<br />
BLAH2<br />
)<br />
<br />
Then you would create your constraints like this:
<br />
ALTER TABLE Table2 ADD CONSTRAINT FK_Table2_Table1 FOREIGN KEY(<br />
Table1ID<br />
) REFERENCES Table1 (<br />
ID<br />
)<br />
<br />
<br />
ALTER TABLE Table2 ADD CONSTRAINT UK_Table2 UNIQUE(<br />
Table1ID<br />
)<br />
|
|

|

Sorry, I forgot to specify. If you have a One-to-Many relationship you would like to enforce then all you need is the FOREIGN KEY constraint. If you have a One-to-One relationship then you need both the FOREIGN KEY and the UNIQUE constraints.

i have 3 columns in my table the room,timeStart,timeEnd.
For example i have inserted this data
room: room1
timeStart: 2007-03-02 8:00 AM
timeEnd: 2007-03-02 3:00 PM
Here's the data that will not be accepted if try to insert
room: room1
timeStart: 2007-03-02 9:00 AM
timeEnd: 2007-03-02 4:00 PM
because the timestart is between the timeStart and the timeEnd. Room1 will only be occupied after 3:00 PM.
Can you help me with this?.
Thank you very Much
Bernie

Use Trigger and put your condition there
|
|
|
|
|
Can u show me the posible code for that?..
Is it posible to use the CHECK CONSTRAINT?.
CONSTRAINT chk CHECK (timeStart BETWEEN timeStart AND timeEnd)
Can i use SELECT statement IN CHECK CONSTRAINT?
