Count errors and not display any less than a value

I have this query that works as it is. I want to modify it so that I do not see Alarm errors less than 50.

I guess it would have to be a sub query to this;

SELECT WaysideName, ST, AlarmMessage, COUNT(AlarmMessage) AS Error_Count, CONVERT(char(10), EventDate, 111) as ErrorDate
FROM AlarmsList
where EventDate >@StartDate and EventDate <dateadd(day, 1,@enddate)="" and="" alarmmessage="" not="" like="" ('%off')="" ('%restored')="" <=""> 'OPERATIONAL AND HEALTHY'
GROUP BY WaysideName, ST, AlarmMessage, CONVERT(char(10), EventDate, 111)

Thanks,

Try this:

SELECT WaysideName, ST, AlarmMessage, COUNT(AlarmMessage) AS Error_Count, CONVERT(char(10), EventDate, 111) as ErrorDate
FROM AlarmsList
where EventDate >@StartDate and EventDate 'OPERATIONAL AND HEALTHY'
GROUP BY WaysideName, ST, AlarmMessage, CONVERT(char(10), EventDate, 111)
HAVING COUNT(AlarmMessage) >= 50

Adding the HAVING clause modifies the query so that only rows with an alarm message count >=50 are included in the output.

Thanks. The important thing to remember here is that the WHERE and HAVING clauses provide different ways of filtering the output of a query.

A WHERE clause is used to filter non-aggregated data.
A HAVING clause is used in conjunction with a GROUP BY clause to filter data aggregated in that GROUP BY clause.

Nested Stored Procedure

Hi!
I have the following two stored proceures:

SP1:

Create PROCEDURE SP1
	@arg1 varchar(100),
	@arg2 varchar(100) out
AS
BEGIN
SET @arg2=arg1+': SP1 Data'
return
END

SP2:

Create PROCEDURE SP2
AS
BEGIN
Declare @argloc varchar(100)
EXEC SP1 'SP2 Data',@argloc
print @argloc
END

On calling SP2 i want result like:

SP2 Data: SP1 Data

But it returns:

SP2 Data

How can can i fix this problem?
Thanks!

This should work:

Create PROCEDURE SP2
AS
BEGIN
Declare @argloc varchar(100)
EXEC SP1 'SP2 Data',@argloc OUTPUT
print @argloc
END

You needed to mark @argloc with the OUTPUT keyword in order for this variable to receive the output value from SP1.

Is there any mechanism to refresh a dataset automatically when the data source ,lets say
a table in SqlServer, is updated, deleted or inserted. No periodic fill or execuete a sql statement please.

Thanks

I don't know when the original data source is updated by other user or
an other aplication.
My project is going to be part of a plant automation system. So the events from the
plant level my arise in very short time duration or too long. It depends on the condition
at that moment. So if I periodically fill my data set, what will be the period?
It is very difficult to gess id advance. Having it too short will bring unnecessary workload
for the system. Or having it too long will cause to miss the some indermediate update in
the data source.

I am not very good on Ado.Net. I need to know ,if possible, can I have my client application
to refresh its dataset (automatically) from the data source when it is updated.

Thanks for reply, anyhow

Why would you want to do this? If you have SQL Server 2005, install the SQL 2005 client tools.

Actually you are not giving the size of varchar so by default it will take varchar(1) and you will not be able to insert the record which is greater than 1 character. You have to do like this:-

Create Table Purchase (Name varchar(50),Amount numeric(10,2))

1 . Gaytri it may possible that racords are not matche
2. Or Pass the Date as 07/25/2007 not 7/25/2007
Old tA.CreateDate = '7/25/2007' i think it is problem
New tA.CreateDate = '07/25/2007'

Ok then doing This way

convert(varchar,tA.CreateDate,101)='07/25/2007'

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
