Transact SQL :: How To Create UNION Clause With Two Queries That BOTH Have WHERE Clause
Nov 4, 2015
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

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?

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'
from EventStrings ES
JOIN schedules s
ON ES.SchId=S.SchId
JOIN vehicles v
ON v.vehicleid=es.vehicleid
JOIN Events PO
ON PO.schid=es.schid
AND PO.EvStrId=ES.EvStrId
AND po.activity=4
JOIN Events PI
ON PI.schid=es.schid
AND PI.EvStrId=ES.EvStrId
AND pi.activity=3
WHERE es.providerid in (0,1,4)
and s.ldate>=?
and s.ldate<=?
and v.mdtid=20411
order by s.ldate desc
RESULTS 1
DATE MDT IDPU Odometer DO Odometer Total Miles
12/6/2007 2041112810.6 12874.5 63.9
QUERY 2 (with Union)
select top 1 (s.ldate), v.mdtid, po.odometer, pi.odometer, (pi.odometer-po.odometer) as 'Total Miles'
from EventStrings ES
JOIN schedules s
ON ES.SchId=S.SchId
JOIN vehicles v
ON v.vehicleid=es.vehicleid
JOIN Events PO

AND PO.EvStrId=ES.EvStrId
AND po.activity=4

and s.ldate>=[From Date,Date]
and s.ldate<=[To Date,Date]
and v.mdtid=20411
Union
select top 1 (s.ldate), v.mdtid, po.odometer, pi.odometer, (pi.odometer-po.odometer) as 'Total Miles'

As you can see, the results are sorted very differently. Is there any way to have the order by apply to both queries?
Thanks!

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.

I am having a heck of a time figuring out what controls how/when the generated SQL for a report puts a DISTINCT clause in front of it.
For instance, not that this report makes any sense, but I have 58 rows in my fact table/entity €“ If I pull in a lookup field and execute, the distinct is put in the query and I basically get a list of the possible domain values. It runs the whole joined table query to get them, but it does list (in this case) just 4 records. Now I put in the primary ID of the fact entity and the distinct goes away and I get my 58 rows. If I put two lookup fields, the DISTINCT is back. If I pull in the description field (text string just a direct source field mapping not part of the identifying attributes), the distinct is there. If I pull in the Company Name field on a different entity (which is essentially the same as pulling in Description only it is part of the identifying attributes), there is no DISTINCT. I can pull in all my fields on this entity and none of them drive the distinct. And I swear (ok, I am probably lying but not on purpose) the field/attribute and roles properties are all the same on the attributes. But you get my general question/situation...
Any insight for me? Does it have to do with how I am building the report rather than the underlying model?
Thanks in advance,

Hi Guys,
I am having trouble with a particular query that is beyond my scope of understanding.
Basically I need to pull sales records based on the following criteria:
I have CustomerID, InvoiceNumber, ContractEndDate, MobileNumber, etc..
Customers recontract their mobile phone plans through us, and we have a new sales record for each time they recontract.
For example, CustomerNumber 123 has recontracted 3 times..
once on 2006-01-01, then on 2007-02-12, and finally on 2008-02-15..
So they have a 12 month contract each time.. then come in to recontract it.
So.. a customer has a single Customer Detail record, but may have many sales records attached. And a customer may have several sales for the SAME mobile phone number.
Currently to pull ALL sales records for all customers, my query is this:
Code:
SELECT xxx.CustomerID AS xxx_CustomerID,
xxx.Invoice AS xxx_Invoice,
yyy.PhoneType AS yyy_PhoneType,
yyy.PlanType AS yyy_PlanType,
yyy.ContractEnds AS yyy_ContractEnds,
yyy.MOB AS yyy_MobileNumber
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE yyy.ContractEnds IS NOT NULL
AND xxx.CustomerID IS NOT NULL
We want to get a list of customers that we can call to recontract, based on the ContractEnd field.
However, we want UNIQUE mobile phone numbers, with the LATEST ContrtactEnd date.
So, Customer 123 has 6 sales, for 2 unique Mobile numbers, the sql may be like:
Code:
SELECT MAX(yyy.ContractEnds) AS LatestCED, yyy.MOB
FROM dbo.SaleControl xxx INNER JOIN dbo.SaleDetails yyy ON xxx.Invoice = yyy.Invoice
WHERE xxx.CustomerID='123'
GROUP BY yyy.MOB
Now, this works fine, and of course if i remove the WHERE clause, it collects all unique mobiles, with latest ContractEnd date for each, for all customers. (Customer 123 displays 2 mobile numbers, each with the LATEST ContractEnd date)
BUT i need this information ALONG WITH the other fields (xxx.CustomerID, xxx.Invoice, yyy.PhoneType, yyy.PlanType) and i have tried a few ways of doing it, but can't get my head around it..
Keep getting errors about Aggregate functions and Group By clause, and i understand why i am getting them, just cant think of any alternative query.
Can anyone please help me!
Thanks guys,
Mick

Hi,
Consider the following situtation.
ReportModel is created using named queries. It has multiple entities.
Report Model is deployed to the report server and datasource is set dynamically at runtime(programmatically). When user runs the report (which is created using report model above), I need to change the where clause of one of the entities in ReportModel. How can i acccomplish this programmatically?

When building stored procs, I typically have several nullable parameters. Then in the where clause I will either do this
WHERE (@MyParam IS NULL OR MyColumn = @MyParam)
or this:
WHERE MyColumn = COALESCE(@MyParam, MyColumn)
Lately, I've noticed that either of these imposes a performance penalty. In other words, if I change the first one to
WHERE MyColumn = @MyParam
without the IS NULL, it is noticeably faster. If I only have one or two nullable parameters, I can separate the logic using IF/ELSE, but it becomes huge if I have a bunch of nullable params.I've looked at the execution plans.

I am trying to update a table and then also use OUTPUT clause to capture some of the columns. The code that I am using is something like the one below
UPDATE s
SET Exception_Ind = 1
OUTPUT s.Master_Id, s.TCK_NR
INTO #temp2
FROM Master_Summary s
INNER JOIN Exception d
ON d.Id = LEFT(s.Id, 8)
AND d.Barcode_Num = s.TCK_NR
WHERE s.Exception_Ind IS NULL
The above code is throwing an error as follows:
Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113
The multi-part identifier "s.Master_Id" could not be bound.
Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113
The multi-part identifier "s.TCK_NR" could not be bound.

I have a small table named Exclude_Cusno_Item that has a varchar(29)Â field named
ITEM. When I query the table to show all of the records like this:
Select * from Exclude_Cusno_Item
The result set contains a record with 'AAA' in the ITEM field. However, where I write a query with a WHERE clause to select this specific 'AAA' record like this:
Select * from Exclude_Cusno_Item where item = 'AAA'
I get no results. What could be happening that would prevent the 'AAA' record from appearing in the result set of this query? Note that the 'AAA' entry has no trailing or leading blanks.

I'm struggling with the syntax for qualifying an openquery's results with a where clause. I copied this from examples on the web but get the error  incorrect syntax near '32810'.
declare @sysid varchar(50) = '32810C534D01C920E7CB07EBC0A80122'
declare @sql varchar(500) =
'select * from OPENQUERY(WAREHOUSE,''select * from xxx.yyyy where sys_id = ''' + @sysid + ''''')'
exec(@sql)
selecting @sql it looks like

I have a scenario where the End User is going to select two parameters. @AgentID and @Location If the End User selects @AgentID parameter, in my WHERE clause, I do not want to check the location condition. By default, the agent knows their location already.
If the End User select @Location parameter, in my WHERE clause, I still want to check the Agent condition.
@AgentID parameter would populate either with "All" or their actual agent# (76754 for example).
@Location parameter would populate either with "All" or their actual location (Birmingham or Bessemer for example)Sample of my current WHERE clause:
WHERE
Â
 gl.ReceiptDate >= @BeginDate and gl.ReceiptDate < DATEADD(D,1,@EndDate)
 AND gl.AgentId = CASE WHEN @AgentID = 'All' THEN gl.AgentID ELSE @AgentID END
 AND gl.Location = @Location

Hi,
I have a project which is need dynamically t-sql clause...I've created interface for the create dynamic t-sql clause.
But the clause should get data from relational database. It needs inner join...so it's very hard to do it..
for example
lkpProduct
id product
1 Mouse
2 Keyboard
3 Modem
4 Monitor
main
id productid
1 4
2 1
3 2
4 3
5 4
You can get this table with 2 ways like this..
1. Select main.id, lkpProduct.product from main,lkpProduct where main.productid = lkpProduct.id
2. Select id, case productid when 1 then 'Mouse'.....end as product from main
mytable
id product
1 Monitor
2 Mouse
3 Keyboard
4 Modem
5 Monitor
My question is; how can i use CASE function dynamically ?? Mouse should get from lkpProduct....I do not want to write long table manually..
I hope it is clear for you..
Regards.

I've got this set of registers (just an example) after ordering by the first 3 columns:
value_A value_B value_C ID date
1 2 3 YVIR 29/08/2015
1 2 3 ANTE 27/04/2015
1 2 3 REGO 20/02/2015
I need to get as a final result:
value_A value_B value_C ID date
1 2 3 REGO 29/08/2015
In other words, I need to get, after ordering the result by the date field, the most recent date but at the same time the oldest ID in the list.
I've been trying to do this with the group by clause:
select
value_A, value_B, value_C, min(ID), max(date) -- or max(ID)
from table
group by value_A, value_B, value_C
But in the field ID I'm getting the wrong result because this value is been associated with the alphabetic order.
In access this query involves the function LAST, but in SQL I have not found a good way to perform this. And I am asking because I have seen some possible solution but almost all of them involving the UNION operation, but my problem is, this table can have more than 350.000 registers.
This table is update by some one else, I just can access the information and use it as a source.

I have used the below update query. However, its updating only the first value. Like its updating AB with volume when c.Type = ABC, similarly for CD. Its not updating based on the 2nd or the next case condition.
Â
Update XYZ Set AB = a.Amt * (CASE WHEN c.Type = 'ABC'Â THENÂ (c.volume)
 WHEN c.TYPE = 'DEF' THEN (c.volume)
 WHEN c.Type = 'GHI' THEN (c.volume)
 Else 0
 END),
 CD = CASE WHEN c.Type = 'MARGIN' THEN '4105.31'
 WHEN c.Type = 'ABC' THEN '123.1'
 WHEN c.Type = 'DEF' THEN '234.2'
WHEN c.Type = 'GHI' THEN '567.1'
END
 from table1 a join table2 b
 on a.Cust = b.Customer
 join table3 c
 on b.account = c.account and b.channel =c.channel
Why its not working properly? But if i use Select statement instead of update query its working properly.

My source table has two columns... Policynum and PolicyStartdate and data looks like..

163JÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 05/25/2012
Now my output should return based on 3 parameters..
First two parameters are date range... let say @fromdt and @todt
Third parameter is @policynum
Scenario-1: Enter dates in date range param and leave policynum param blank
Ex: policystartdate between '01/01/2012 and '01/31/2012'.... It returns 1st and 3rd rows from above in the output
Scenario-2: enter policy num in policynum param and don't select any dates
Ex:Â policynum ='456D'Â Â Â Â It returns 2nd row in the output
Scenario-3: Select dates in date range param and enter policynum in param
Ex: policystartdate between '01/01/2012 and '01/31/2012' and policynum
='163J'. it should return only 4th row even though dates were selected(Override date range when policynum is entered in param and just return specified policynum row in the output)
I need t-sql code to get above results.

I 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 TrackID

I'm asking my previous question in this new thread with more specific data and condition.I have below sample data,
DECLARE @DATA TABLE (U_ID INT, U_NM NVARCHAR(20), U_DT DATE, U_ORD INT, P_U_NM NVARCHAR(20) NULL)
INSERT INTO @DATA VALUES (1, 'Design', '06/15/2015', 2, NULL), (1, 'Plan', '07/01/2015', 1, NULL), (1, 'Cust Plan 1', '06/10/2015', 0, 'Plan'), (1, 'Cust Plan 2', '06/05/2015', 0, 'Plan'),
(2, 'Design', '06/25/2015', 2, NULL), (2, 'Plan', '06/20/2015', 1, NULL)
We have 2 different U_ID (1, 2) and I want a SELECT query to display,
1. For U_ID = 1, we have 2 parent U_NM (Design & Plan) and Plan having 2 child (Cust Plan 1 & Cust Plan 2).
2. I want to display parent U_NM ORDER BY U_ORD
3. If any parent having child element, then need to show immediately under that parent and ORDER BY U_DT
4. For U_ID = 2, we don't have any child, hence display ORDER BY U_ORD

I'd like to modify the dates within this where clause to be dynamic, building the date depending on the current year, but everything I try doesn't seem to be syntactically correct.
SELECT *
FROM Openquery(LS_CIS, 'select * from BI_WRKFLW_TASKS where (BI_EVENT_DT_TM>=''1/1/2011'' and (BI_NEEDED_DT_TM>=''1/1/2011''))OR (BI_EVENT_DT_TM>=''1/1/2011'' and BI_NEEDED_DT_TM is null)') AS derivedtbl_1
I'd like to replace ''1/1/2011''Â in the where clause with something like:
CAST(CAST(YEAR (GETDATE())-4 AS varchar) + '-' + CAST(01 AS varchar) + '-' + CAST(01 AS varchar) AS DATETIME)
