I presume he means a query that in its entirity is SELECT 1
It is, after all, a valid query. (By that I mean that SQL Server will process it and produce a result set from it)

I presume you found this in a stored procedure. It is often used to return a result back to the caller. It is especially useful when the stored procedure is invoked from a .NET application with ExecuteScalar()

I have two date pickers that can be selected by the user. If the span of these two dates fall between a specific date in the database, then a message should appear. I don't know know how to check these dates using SQL.
I know that I can check one date to be between two dates in the database, I just don't know how to check if any part of an entire date span falls between these values.
Please help!

I have two date-time pickers. One is the start date of an event, and the other end date.
If I want to add another event with a start date and an end date, then I must run an SQL statement to check if the new event date does not overlap the date of a previous event.
So far, I only know how to check whether the start date or end date of an existing row in the database is between the start date and end date of the new event. I need to check the complete date against the new event date. Thanks

I am not sure if I've got your concern at the right end, my apologies if I am wrong.
Probably you can introduce a new column in the dB indicating that the specified range of date(s) is/are already blocked for an event.

Its not really what I am looking for, but I am willing to try. Unfortunately, I don't know how to implement this. Thanks

Range comparisons are not that horrible if you break them down. In order for a range to overlap, the first requirement would be that the New.StartDate is less than (or equal too) the Stored.EndDate. If not, then they don't clash. If it is true, then see if the New.EndDate is greater than (or equal too) the Stored.StartDate. If this is also true, then you have an overlapping range.
In a stored proceedure it would look something like this:
IF EXISTS(SELECT *
FROM [MyTable]
WHERE
@StartDate <= [EndDate] AND
@EndDate >= [StartDate])
BEGIN
END
ELSE
BEGIN
END

What I do, with all the types of database I've yet encountered, is to use the DataReader's GetSchemaTable method.
(I use C#)
Open the connection -- con.Open() ;
Set the command -- cmd.CommandText = "SELECT * FROM table" ;
Use ExecuteReader -- reader = cmd.ExecuteReader() ;
Call GetSchemaTable -- table = reader.GetSchemaTable() ;
Cancel the Command -- cmd.Cancel ; (Not all databases support this.)
Close the DataReader -- reader.Close() ;
Close the connection -- con.Close() ;

No you can't. You have to query against the table with the id to get the information.

This is not possible becasue tables in SQL Server are not physically linked.

Hi there,
Hope someone can help me,
I'm trying to resolve orphaned users in SQL server.
I created a procedure that works very nice in SQL server 2005, but it's having problems in SQL server 2000.
Here is the problem part of my code:
create table #Users(
username varchar(20),
userId varchar(250))
insert into #Users
exec sp_change_users_login 'Report'
select * from #Users
Then I get this error:
Server: Msg 15289, Level 16, State 1, Procedure sp_change_users_login, Line 27
Terminating this procedure. Cannot have an open transaction when this is run.
Hope you can help.
Thank you

Hi again,
Ok, I'm going to post my own fix on this :P
But would still like ideas on the original problem, if someone has.
I basically just did what the SP did in a short query:
select name AS UserName, sid AS UserSID
from sysusers
where issqluser = 1
and (sid is not null and sid <> 0x0)
and suser_sname(sid) is null
order by name
Kind regards
