I have 2 tables(Customer,Staff) with the same column name 'email'. I would like to join both tables together where email="xxx@xx.com" to check if email exist already in the database. I have tried
Code:
Select email from (select email from staff union select email from customer) as 'CombinedEmail' where email = 'xxx@xx.com'
But it does not work at all. Is there anything wrong with my codes?
I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?
sql = "Select c1 from t1
sql = sql & " Union Select c1 from t2 Order By c1"
t1=c1 = 1,2,3
t2=c1 = 200,5,300
datatype=nvarchar
result is not ordered as 1,2,3,4,200,300 why
Hi,
I'm currently have a problem with a query using a top clause. When I run it by itself as a single query, I have no problems and the results are valid. However, if I try duplicate the query after a union clause, the order by ... desc doesn't order properly.
The following is the query I'm using along with the results. Then I'll have the query I was trying to unite and the results (date ranges selected were the same in both):
QUERY 1
select top 1 (s.ldate), v.mdtid, po.odometer, pi.odometer, (pi.odometer-po.odometer) as 'Total Miles'

Hi all,
I have two table having datas like
Table1
--------------------------------------------------------------------
A C1 C2 C3 C4
--------------------------------------------------------------------
x 0 0 3 2
x 0 1 0 2
x 0 0 2 1
y 1 5 2 0
Table2
--------------------------------------------------------------------
A C1 C2 C3 C4
--------------------------------------------------------------------
x 0 0 1 4
y 1 0 3 1
y 1 2 0 0
y 0 0 5 1
select * from(
select A,C1,C2,C3,C4 from Table1 group by A
union
select A,C1,C2,C3,C4 from Table2 group by A
)as t
Result:
--------------------------------------------------------------------
A C1 C2 C3 C4
--------------------------------------------------------------------
x 0 1 5 5
y 1 5 2 0
x 0 0 1 4
y 2 2 8 2
But i need the result like i.e grouped by column 'A'
--------------------------------------------------------------------
A C1 C2 C3 C4
--------------------------------------------------------------------
x 0 1 6 9
y 3 7 10 2
select * from(
select A,C1,C2,C3,C4 from Table1 group by A
union
select A,C1,C2,C3,C4 from Table2 group by A
)as t group by A
The above query gives the following error
[Error Code: 8120, SQL State: S1000] Column 't.C1' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Please help me out.

SQL Server 2008 r2...
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
FROM[UT_Pole] A
LEFT OUTER JOIN [UT_Surveyed_Pole] B ON A.[PoleID] = B.[PoleID]
[Code] .....
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'
) as t
order by [name]
--result:
---------
--1 G
--2 R
--4 Z
--3 Z
select * from (
select id=3,[name]='Z'
union select 1,'G'
union all select 2,'R'
union all select 4,'Z'
) as t
order by [name]
--result:
----------
--1 G

Hi all,
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 ?

View 3 Replies View RelatedI am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)
2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)

In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Hi,
What is HAVING clause equivalent in the following oracle query, without the combination of "GROUP BY" clause ?
eg :
SELECT SUM(col1) from test HAVING col2 < 5
SELECT SUM(col1) from test WHERE x=y AND HAVING col2 < 5
I want the equivalent query in MSSQLServer for the above Oracle query.
Also, does the aggregate function in Select column(here the SUM(col1)) affect in anyway the presence of HAVING clause?.
Thanks,
Gopi.

AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null)
whered1.ImplicitID >= d2.ImplicitID AND
(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate,

(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
another thing...
if we put AND d1.ImplicitID = d1.ImplicitID condition in second query then shall we remove
d1.ImplicitID >= d2.ImplicitID from WHERE clause????

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 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')

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.

Of the two queries below, the first returns the desired result, the union of the select-except statments. Why doesn't the second query return the same result as the first? Is this a mistake/bug on Microsofts side?

When any changes have been made to the underlying table structure, the Union all reports error and does not automatically correct the error. I then have to delete it and recreate it. Is this a bug?
