For a Union All of Views where both views look at the same openrowset file I get
[OLE/DB provider returned message: Unspecified error]
OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0' IDBInitialize::Initialize returned 0x80004005: ].
Msg 7399, Level 16, State 1, Line 2
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.
This probably occurs because the first view keeps the file open.
Any workarounds on this?
I have a union view that unions 36 tables which have a date constraint set on the datetime field, the data for which is is same for all records within the respective tables. The purpose of this is to allow users to go straight to the month that they require. This works fine with raw sql queries using hardcoded dates , the query plan shows that only the required tables are accessed. However, if i create a lookup table (this is for business objects), join the union view date field to date field and use a between criteria, it ignores the constraint and scans all 36 tables in the view. Changing the between to = shows that the constaint is used. Does anyone have any ideas here , i seem to have tried everything

Hey
I am very new to database and have a question about views, that I hope someone can help me with, i am sure its simple:
I have to tables for storing different users, I want(for a log in function),to make a view that combine these to tables.
so all names stored in table1 under column customer_name, and all names stored in table2 under column name contact_name will in the view be stored under column username.
What shall a do?
Thanks for all help

I have a query which does 3 selects and Union ALLs each to get a final result set. The performance is unacceptable - takes around a minute to run. If I remove the Union All so that the result sets are returned individually it returns all 3 from the query in around 6 seconds (acceptable performance).
Any way to join the result sets together without using Union All.
Each result set has exactly the same structure returned...
Query below [for reference]...
WITH cte AS (
SELECT A.[PoleID], ISNULL(B.[IsSpanClear], 0) AS [IsSpanClear], B.[SurveyDate], ROW_NUMBER() OVER (PARTITION BY A.[PoleID] ORDER BY B.[SurveyDate] DESC) rownum

LEFT OUTER JOIN [UT_Surveyed_Pole] B ON A.[PoleID] = B.[PoleID]

Why the sequence different?
select * from (
select id=3,[name]='Z'
union all select 1,'G'
union all select 2,'R'
union all select 4,'Z'

Fellow database developers,I would like to draw on your experience with views. I have a databasethat includes many views. Sometimes, views contains other views, andthose views in turn may contain views. In fact, I have some views inmy database that are a product of nested views of up to 6 levels deep!The reason we did this was.1. Object-oriented in nature. Makes it easy to work with them.2. Changing an underlying view (adding new fields, removing etc),automatically the higher up views inherit this new information. Thismake maintenance very easy.3. These nested views are only ever used for the reporting side of ourapplication, not for the day-to-day database use by the application.We use Crystal Reports and Crystal is smart enough (can't believe Ijust said that about Crystal) to only pull back the fields that arebeing accessed by the report. In other words, Crystal will issue aSelect field1, field2, field3 from ReportingView Where .... eventhough "ReportingView" contains a long list of fields.Problems I can see.1. Parent views generally use "Select * From childview". This meansthat we have to execute a "sp_refreshview" command against all viewswhenever child views are altered.2. Parent views return a lot of information that isn't necessarilyused.3. Makes it harder to track down exactly where the information iscoming from. You have to drill right through to the child view to seethe raw table joins etc.Does anyone have any comments on this database design? I would love tohear your opinions and tales from the trenches.Best regards,Rod.

I have a Union All transformation with 4 inputs and one output when I debug the package the sum of the different inputs rows does not match the row count in output.
I don't understand, I've used the Union All transform many times and I've never seen this.
Any idea why this could happen ?
Hello.
Newbie here. I've only been using SQL for about a year now and have some minor questions about sql objects that reference other objects.
We have some views which reference other views in the joins. I will call one the primary view and the one being referenced in the joins as the secondary view.
Recently we made changes to the secondary view.
After which the primary views which referenced it would not work because of this change and had to be 'refreshed' by using drop/create scripts which essentially just dropped it and recreated the exact same view. I do not recall the exact error message that was returned other than it seemed to suggest that it could no longer see the secondary view since it had been changed. Nothing in the primary view was changed in any way, just the secondary.
Some here where I work have suggested off hand that this was a recompile of the primary view because the contents of the secondary changed.
My questions are:
1. Exactly why did this happen and is there a proper name for it when it does?
2. The same problem does not seem to occur when we have stored procedures referencing views in the joins which had just been changed. Why is that?
Thanks for any help on the matter. I greatly appreciate it.
Hello,
to make a report easier I'm developing it using a view of joined views of joined views.
Is there any significant performance penalty as opposed to just having one big select?

Hello There,I'm trying to create a view that has calculations dependent oncalculations, where the problem resides is that each time I make acalculation I must create an intermediate view so I can reference aprevious calculation.for example lets say I have my_table that has columns a & b. now I wanta view that has a & b, c = a + b, and d = c + 1.this is grossly simplified, the calculations I actually use are fairlycomplex and copying / pasting them is out of the question.so what I have is my_view_a which makes column c, and my my_view_finalwhich makes column d (however, in my real application I have 5 of theseviews, a/b/c/d/e/)is there anyway I can consolidate all these views into one? I wasthinking of using a stored procedure with temp tables or somethingalong those lines.I just which I can use the aliases that I create for c in d in onestep.any insight would be greatly appreciated.

Hi
I just found out that I can do an ORDER BY clause on entire records set retrieve from a query that combines several sub queries with UNION from different tables with the same structure... so this is great to know, BTW, is this a new feature of MSSQL 2K ? I don't recall being able to do this in MSSQL 7 or 6.5.
Anyway, the main question is, can I use the TOP command in a query that has UNION in it?? Meaning, there are two queries (or more) from two tables (or more) and I need to fetch the top 10 records by an ORDER BY clause from the combined results, when I try to add each sub query TOP 10 the results are not correct at all, when I try to add TOP 10 only to the first query hoping that the analyzer will refer to the whole query, it's selecting TOP 10 from the first query and combines it with all the records from the others...
So, can anyone help? I hope the problem is understood.
Thank you,
Inon.
Hi!
I am trying to join to different queries into one table ( I accomplished this)
Next I need to ADD or SUM the results of 2 rows to form a single row.
As you can see in the query below, I run 2 separate queries and use ' ' as a place holder for the UNION to work. I get duplicate rows, one with a value and the other with a '0'. I want to have a single row.
Any help is greatly appreciated!

From BOL:
By default, the UNION operator removes duplicate rows from the result set.
If you use ALL, all rows are included in the results and duplicates are not
removed.
Why is it assumed that one would want the duplicates removed by default?
Isn't that what SELECT DISINCT is for?
I was wondering if there is a way I could write this query as one query using union instead of 3 different queries?
SELECT columna as column,count(ID) as Applications
FROM tablea
GROUP columna
SELECT columna as column2, count(ID) as Approved
FROM tablesa where substring(APP_DATE,1,6) >'200304' and in 'Approved')
GROUP BY columna
SELECT columna as column3, count(ID) as Booked, sum(AMT) as amt, sum(AMT)/count(ID) as lavg
from tablea where substring(APP_DATE,1,6) >'200304' and STATUS in('book')
group by columna
Hi All,
I am doing a UNION of 8 views(with 3 million rows in each view approx). I am sure that there is NO DUPLICATE data between the views. SO specifying a UNION ALL would be better than specifying a UNION in this case?

Hi folks,
I have a question about the performance of the following query:
(SELECT name, lastName
from Data
where salary >= 2200
)
union
(SELECT name, lastName
from Data
where salary >= 2200
) union
(SELECT name, lastName
from Data
where salary >= 2200
)
How that query works? Is it slow for a larger data? Does it do 3 queries and then combine them?
Thank you.

I want to know the top 5 patterns in sales, the report will like this:

2005-07 B1 B2 B3 B4 B5
2005-08 C1 C2 C3 C4 C5

What I did is:
declare @StartDate and @EndDate, set @StartDate and @EndDate
Delete AAAA (AAAA is a table)
Begin
While (@EndDate<somedate)
Insert into AAAA(sales, Month, Pattern)
Select TOP 5 sales, Month,pattern from sometables order by sales DESC
increase @StartDate and @EndDate by a month
End
Select * from AAAA
It works fine. My question is: Can I get rid of table AAAA? Is there a better way that just use Top 5 combine with something say Union? ( I tried Union and failed )

The first comment, by 'zpeceno', exactly describes a problem that I have hit upon.
However despite looking thro the list of issues resolved in SP1, I've found no mention of it.
Any chance I could get some offical comment re. the bug described, when it was(/has it been?) officially acknowledged, and what service pack (if any) resolves it?
Many thanks,
