Hi,
you can use SELECT DISTINCT[^] and ORDERBY to get an ordered list of all different company names present.
you can't find the "shortest" names as in your example, it would only give "Comx", not what you said it would.

Hi.
I wrote some VBA underlying code for an Access 2000 application and used to create/open recordsets in the following manner:
Dim rstLookupFixedAreas As New ADODB.Recordset
rstLookupFixedAreas.Open "tbl_FixedAreas", CurrentProject.Connection, adOpenStatic, adLockOptimistic
rstLookupFixedAreas.MoveFirst
Do Until (rstLookupFixedAreas.EOF)
strValueList = strValueList & CStr(rstLookupFixedAreas.Fields(0)) & ";" & rstLookupFixedAreas.Fields(1) & ";"
rstLookupFixedAreas.MoveNext
Loop
comboFixedArea.RowSource = strValueList
'comboFixedArea.DefaultValue = 1
rstLookupFixedAreas.Close
I did this by including the reference to Microsoft ActiveX Data Object 2.1 Library.
Now that I am using Access 2007, is there a more current method to do the same type of "recordset" operations? (or should i continue with including ADO 2.1 Library)
I want to use either a record index or Find method to get my record pointer.
Thank you for the help.

I have a .csv file with following column:
Col1,Col2
And the data table has one extra datetime column:
Col1,Col2,TimeStamp
While importing data using BULK INSERT from the CSV, is there a way to specify the value for the TimeStamp column too? (Timestamp would be same for all the newly imported rows)

How about defining a default value for the column?
ALTER TABLE dbo.tablename ADD CONSTRAINT
DF_TimeStamp DEFAULT '20091218' FOR TimeStamp

That may not work since the timestamp is same only per bulk insert. I do have a solution for this, wrap bulk insert inside a stored proc, and update the the timestamp from SP. But this would introduce few additional steps, was wondering if this can be avoided in case if BULK INSERT already has this feature.
Thank you,

I have a time series data in which a numerical indicator fluctuates over time. If I want to find out for which given day, this indicator has crossed above 30 in the past 3 days. Is it possible to write a SQL query that retrieve this information?
The logic to check for the crossing movement is:
IF indicator(day x) > 30 AND indicator(3 days ago from day x) <30 THEN
Return "YES WE HAVE AN UPWARD CROSSING MOVEMENT THROUGH 30 FOR PAST 3 DAYS!"
END IF
Can this be accomplished using a SQL CASE statement with a HAVING clause or something else?
I'd greatly appreciate any help! If possible please provide a sample code 
|
|

|
|
An exists should do it - as far as I can tell from your description
select column_list....
from table1 t1
where indicator > 30
and exists (select 1 from table1 t2 where t2.pk = t1.pk and t2.indicator < 30 and t2.dateadded = dateadd(day,-3,t1.dateadded))
where PK is your primary key
[Edit] I had missed the date bit from the exists originally [/Edit]

Hi Ashfield, Your code looks exactly like what I need! I'll give it a try after getting home.
Many thanks again.

that is all child records should be displayed next to parent.

If you tell us that the fourth field is the parent's ID (and the first field is its ID), then we will have an easier time trying to figure out what you want.

Hi!
Can someone please tell me how would I go about creating a Stored Proc to select records between dates?
I have 2 variables, date1 and date2 I want to create a stored proc as follows:
select * from table between date1 and date2 where the dates are variables in the stored proc.
Illegal Operation
|
|
|
|
|
select * from table
where datecolumn between date1 and date2
e.g.
declare @t table(activity varchar(10),datecol datetime)
insert into @t
select 'activity1', '2009-12-01' union all
select 'activity2','2009-12-02' union all
select 'activity3','2009-12-15' union all
select 'activity4','2010-01-02' union all
select 'activity5','2009-12-31'
Declare 2 date variables
declare @date1 datetime,@date2 datetime
set @date1 = '2009-12-01'
set @date2 = '2009-12-15'
I want to select records between 1st Dec 2009 to 15th Dec 2009.
Query:
select * from @t
where datecol between @date1 and @date2
Output:
activity datecol
activity1 2009-12-01 00:00:00.000
activity2 2009-12-02 00:00:00.000
activity3 2009-12-15 00:00:00.000

Hi,
We have event-based data currently being logged in relational database structures. For various reasons this data need to be stored elsewhere, possibly on our existing PI historian database. We need to ascertain whether PI can relatively easily store this type of event based data, and ultimately produce reports using RT Web Parts, also relatively easily. If not, we would rather log it in a SQL Server database.
1. This data are obtained via a SSIS package from flat files and stored in a SQL server database.
2. Currently we have around 550 event based jobs running parallel typically on a daily basis.
3. This constitutes in approximately 100 000 records every 5 minutes being logged. That’s more or less 350 records every single second.
4. These events are currently sorted on a BigInt type incremented number from low to high. Can PI log values at a micro sub second level so that the values can be displayed in the correct order it was logged? Or are there some other way to do this?
5. Note that EvTime only saves at second level. EvSeqNo is necessary here to sort the data sequentially, as many records are logged per second.
6. Can Pi handle this huge influx of data?
7. A sequence can constitute a various number of events, from starting that sequence by starting a job by an operator, holding or diverting it. Starting, holding, diverting and so forth constitutes an event. There are various other events as well
8. A job can start another job as well.
9. EvJob, EvLevel, EvLabel, EvKey,EvText, EvSeqNo are all stored in separate database columns. Must this be concatenated into one delimited string or is there an easier way to store the data in PI?
10. EVJob should typically the tag name. However when a job is started by an operator EVJOb can be something like :Citect which means that the actual job being started must be retrieved from the EvText string.
11. Once all this data is being logged, can it easily be retrieved to display in reports using RT Web Parts?

Hi all
Whilst I have done quite a bit of ASP.Net programming in the past, most of my recent development work has been with Ruby on Rails. I'm now starting up a new project that requires ASP.Net and I'm trying to see how to do a couple of the really great features in RoR.
The main one is database migrations.
In RoR, you have a logical schema for the database tables stored as a series of migrations: each of which contains the changes to up or down the rev level of the database tables. As you develop the models, you add migrations. This makes rapid development involving databases really easy.
Does anything similar exists for VS and ASP.Net? I've been through much of the ASP.Net MVC pages but all the references I've seen are too micky mouse to see anything useful (i.e. they all deal with local MDF databases rather than a remote SQL Server database).
Regards
Gareth
