Hi Mark,
Thanks for your feedback, do you have an example of that?
Is there not a constraint in sybase or something along those lines that I can apply to the column?
Thanks again,
Mel

I have two table which are TBL_A and TBL_B.
TBL_A contain two record, TBL_B have no record.
Select ta.Name
From TBL_A ta
I get two record. But If wrote following query
Select ta.Name
From TBL_A ta, TBL_B tb
No any record get, because SQL Server defaultly use CROSS JOIN like this;
Select ta.Name
From TBL_A AS ta CROSS JOIN TBL_B AS tb
How can I close CROSS JOIN. I want to get record when TBL_B also have no record..
Actually I use "where" statement, but if one table have no record on FROM statement so I did not get result related about CROSS JOIN.

This may help
declare @tblA table(recordA varchar(10))
declare @tblB table(recordB varchar(10) null)
insert into @tblA select 'recA1' union all select 'recA2'
Query:
select a.* from @tblA a full join @tblB b
on a.recordA = b.recordB

| If you did a normal install then the instance name should be the name or IP of the server it was installed on. If you installed a specific instance the name of the server should be servername/instancename. Never underestimate the power of human stupidity

Then you need to do some research, there are plenty of resources on the web and you should have Books On Line (BOL) with your SQL Server. Use them, research instancename.
I think you need to reinstall if you need to change the instance name but I'm not sure.Never underestimate the power of human stupidity

Hello Friends,
I've a date in string variable i want to convert this string into datetime format(mm/dd/yyyy) but it's giving me an error. Because my date is stored in dd/mm/yyyy but sql analyser require datetime in mm/dd/yyyy.
So please suggest me the way. Here is my example
Declare @str varchar(100),@strDate datetime
Set @str='14/02/2010'--(dd/mm/yyyy)
Set @strDate=@str
Print @strDate
|
|
|
|
|
Use the following
Declare @str varchar(100),@strDate datetime
Set @str='14/02/2010'--(dd/mm/yyyy)
Set @strDate=CONVERT(DATETIME, @str,103)
Print @strDate
Look into CONVERT in BOLNever underestimate the power of human stupidity

Try this
Declare @str varchar(100)
Set @str='14/02/2010'--(dd/mm/yyyy)
select ConvertedDate = CONVERT(varchar(10),CONVERT(datetime,@str,103),101)--mm/dd/yyyy
Output:
ConvertedDate
02/14/2010

How could I solve it?
thanks

Obviously IsOnline is not a column in the table. Find out what the column name should be

Yes I know and there is not the same column name in the table but I have to compare it with @UserStatus
|
|
|
|
|
Try this[^]

|
|
|
|

Is the UserStatus a string ? Then the IsOnline should be 'IsOnline' (in quotes).
Or is IsOnline a SQL Server function that you have written ? Maybe it needs a parameter.
|
|
|
|
|
@UserStatus is declared as bit and IsOnline is not a SQL function.
|
|
|
|

It's not legal to filter on a column that doesn't exist before the selection
select 1 as bla
where bla <> 1 This will generate an exception. You'd need to change the condition in your where-clause. Alternatively, you could use a view without the filter, and filter that using a second query.
I'm thinking that IsOnline would be a good candidate to become a computed column.I are Troll

because I use this stored procedure for paging so I need to use IsOnline in first Select statement.

As far as Sql Server is concern, this you cannot do but the same can be done in Oracle.
What you do is like
AND (@UserStatus = (CASE WHEN aspnet_Users.LastActivityDate > @DateActive THEN cast(1 as bit) ELSE cast(0 as bit) end) OR (@UserStatus = 0 AND 1=1))
Hope this helps
