Wondering if there is a physical or realistic limitation to the number
of UNION statements I can create in a query? I have a client with
approx 250 tables - the data needs to be kept in seperate tables, but I
need to be filtering them to create single results sets. Each table
holds between 35,000 - 150,000 rows. Should I shoot myself now?

Hello,
I have two union statements that I need to join to each other. Then I need to join that result to another table. So-
[(TBL-A UNION TBL-B)
JOINED TO
(TBL-C UNION TBL-D)]
JOINED TO
TBL-E
Is this a subquery thing, or something else? I have not been able to figure out how to make it work! The unions I have made work fine though, on their own.
I'm new to SQL stored procedures, but I'm looking to be able to select order by statement.
declare @OrderBy
@OrderBy = 'first_name'
Select first_name,last_name from table1
Union
Select first_name,last_name from table2
if @OrderBy = 'first_name' begin
Order By first_name
else
Order By last_name
end
You'll have to excuse my if statement if the syntax is incorrect (used to only writing asp ifs :P). Thanks for any help
I have some old code consisting of over 30 Union statements, unioning 7/1/15-8/1/15 data according to the below code. Each block is the same except for the date. How could I rewrite these 30 union statements into a more concise query?
Each client (people_id) has a distinct agency_id_number. So the code below totals the number of distinct clients/day and groups them by programs and facilities.
Sample data that you can use to test this report:
IF OBJECT_ID(N'tempdb..#sample_census') IS NOT NULL drop table #sample_census
create table #sample_census
(
start_date datetime,
program_name varchar(25),
facility_name varchar(25),
agency_id_number varchar(25)
)
[Code] ....
Good day all.
Let's see if I can stump you with this one.....
Code Snippet
SELECT Account.New_DistributorAccountNumber, Account.New_NameonBill, ActivityPointer.Subject, ActivityPointer.CreatedOn AS ExprX
FROM Account INNER JOIN
ActivityPointer ON Account.AccountId = ActivityPointer.RegardingObjectId
UNION
SELECT Account_1.New_DistributorAccountNumber AS Expr1, Account_1.New_NameonBill AS Expr2, ActivityPointer_1.CreatedOn AS Expr19,
ActivityPointer_1.Subject AS Expr20
FROM Account AS Account_1 INNER JOIN
Contact AS Contact_1 ON Account_1.AccountId = Contact_1.AccountId INNER JOIN
ActivityPointer AS ActivityPointer_1 ON Contact_1.ContactId = ActivityPointer_1.RegardingObjectId
gives the error mentioned above. Each select statement, when run separately, works fine. Any clues?
Thank you in advance
I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.
“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.
I don’t recall changing anything but I wouldn’t rule that out. I ‘ve inspected the source files and I don’t believe they have changed either.
DECLARE
@FileName varchar(50),
@Path varchar(50),
@SqlCmd varchar(1000)
= '',
@ASXCode varchar(5),
@Offset decimal(18,0),
[code]....
I am using MS SQL server 2008, and i have a table with 350 columns and when i m trying to create one more column its giving error with below message -
Warning: The table XXX has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes.
INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
how can i resolve this?
I have successfully execute a union query. How can i create a make-table query to accomodate the resultset of the union query?

When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
I've got some SQL that works as far as returning a recordset from a series ofUNION statements.viz:SELECT whateverUNION thisUNION thatUNION otherNow I want to group and sum on it's results.Started out tying:SELECT * FROM(union stuff)....but couldn't even get past the syntax check.Where I'm headed is a sort of pivot table presentation of some hours dataassociated with various projects with a column for each of six date ranges.Bottom line: can somebody give me a pointer to the syntax needed to wrap thoseUNION statements and then select/group/sum their results?--PeteCresswell

I am executing a SELECT statement that has about 500 characters of literal characters concatenated with the contents of a field from a table. I am then storing the result to be run as dynamic SQL. I am finding that when run this as select statement in query analyzer, the last part of the literal gets truncated. When I run it as a cursor and store it in a varchar(1000) variable and print the variable everything works fine. In addition when I put the select statement in a stored procedure and return this to a ADO recordset, the resultset is fine as well. But running the stored procedure in query analyzer truncates the results as well. The issue seems to be getting the results of the SELECT in query analyzer. Even running the stored procedure in the SQL area of Enterprise Manager returns a proper result. Has anyone heard of a maximum return from a select in query analyzer?

View 2 Replies View RelatedI need help with a union query. My table structure is as follows:

Hi gusy, this is the first time I am trying to use "Union" query. I am trying to create a view(linking and taking data from 3 tables) so I can create a crosstab report out of it.
Basically one table contains about 12 fields and I am trying to grab data from all of them is they are not null.So this is my query,but when it executes it only dispalys result from the first query,what am I doing wrong.
SELECT dbo.RelocateeRemovalist.RelocateID, dbo.RelocateeRemovalist.RemovalistNumber, dbo.RelocateeRemovalist.SupplierID,
dbo.RelocateeRemovalistAmounts.CarInsurance
FROM dbo.RelocateeRemovalist INNER JOIN
dbo.RelocateeRemovalistAmounts ON dbo.RelocateeRemovalist.RelocateID = dbo.RelocateeRemovalistAmounts.RelocateID
WHERE (dbo.RelocateeRemovalistAmounts.CarInsurance IS NOT NULL)
UNION

Hi, i have a union query that lists all the years from a date field and add the currentyer if its not already listed:
SELECT DISTINCT Cas Yearlist
FROM dbo.ViewPressReleases UNION SELECT datepart(yyyy, getdate())
ORDER BY DatePart(yyyy,[PressreleaseDate])
what i need to do is filter it with something along the lines of:
WHERE Yearlist LIKE myvariable
although i know i cant simply use:
WHERE Yearlist
it would have to be something like:
WHERE DatePart(yyyy,[PressreleaseDate]) UNION datepart(yyyy, getdate()) LIKE myvariable
Does anyone know how to write this correctly?
I've been trying to do a union with a subquery - I've made a differentexample which follows the same principles as follows:First bit brings back accounts which are in the top 10 to 15 by accountname.Second bit brings back accounts which are in the bottom 10 to 15 byaccount name.I want to union the two result sets together. These selects work asthey are, but don't when i take the comment away from the unionoperator.select top 5 c1.accountnofrom tbl_customer c1where c1.accountno not in(select top 10 c2.accountnofrom tbl_customer c2order by c2.accountName asc)order by c1.accountName asc--union allselect top 5 c1.accountnofrom tbl_customer c1where c1.accountno not in(select top 10 c2.accountnofrom tbl_customer c2order by c2.accountName desc)order by c1.accountName descSo my problem is really about how to have an order by in a sub querywhich is then used in a main query which is then unioned with anotherquery - SQL Server doesn't seem to like that combination of things. Anyclues anyone?Cheers,NAJH

View 4 Replies View RelatedHello every body.I have a small issue.Problem: I have a table with 4 descriptor columns (type). I need toformulate a query to retrieve a count for each type so I can groupby...etc. The view I have works, but doesn't work when I supplement thequery with some functions... they just don't like the UNION. The realproblem is I can't change any of the udf's or queries, just the view.The view is inner joined back on to the primary table 'qt_ins' againand a heap of other tables. But for this post and to not complicate ittoo much I've just included the primary table and the view...Also my querys work if I don't put a where clause on for the VIEW. eg:.... and cv.type = 'Environmental'.... for some reason with a clause itgets stuck in an *infinite loop.Conditions: The table structure cannot be changed in anyway. Theview/query must return 2 columns qi_id & type.I considered creating a function to return the Types but then I figuredI would ask you folks for a better way.Any help with the view appreciated.Thank

View 3 Replies View RelatedHi, I have a question,
Im trying to use the UNION ALL statement to join my results.
I have multiple talbes, each table has the table name as a date: 28_1_2008, 29_1_2008, etc..
Some dates dont have tables.
What I want to do is write an sql query that gets all the results from a rage of dates..
ie. range : 27_1_2008 to 29_1_2008
What im doing :
sql1: Select * from 27_1_2008 UNION ALL select * from 28_1_2008 UNION ALL select * from 29_1_2008.
It works fine if all tables exist, but in my data base every date DOESNT NECESSARLY have a table.
ie. say I have tables 27_1_2008 , 28_1_2008, 30_1_2008
Now if I do
sql2: Select * from 27_1_2008 UNION ALL Select * from 28_1_2008
This works.
But,
sql3: Select * from 28_1_2008 UNION ALL Select * from 29_1_2008 UNION ALL Select * from 30_1_2008
Causes an error, and DOESNT return any records..
I need a way so that even if one particular table doesnt exist, the others should be returned.
i.e in sql3, it should skip the non existing "29_1_2008" table, and return the rest. As of now, it doesnt return anything,
Anyone with some suggestions?

Thank You.
currently I am investing some time in learning SQL, I have been working with a sample db, and have come across UNION.
I see many examples showing the same thing, 2 tables with identical datatype and either with a alias or same name. My question is, can a UNION be used for more than 2 tables?
I currently have 3 tables: orders(customerNum,orderNum,orderDate), orderline(orderNum,partNum),
part(partNum,description)
I want to display orderdate and ordernum, only if partNum= 1234 or customerNum= 123
everything is char datatype
I am able to innerjoin, however I am somewhat confused attempting a UNION query. is this possible?
so far
select orders.orderNum,orderDate
from orders,orderline
where orders.orderNum=orderline.orderNum and customerNum='xyz'
union
select orderline.orderNum,part.partNum
from orderline,part
where part.partNum=orderline.partNum and orderline.partNum='abcd'
order by 1
as you can see i am somewhat lost. At the moment the orderDate column is showing partnum and dates. But if someone can show how to make this possible I would greatly appreciate it.
I have a table called dbo.PhoneCalls with below columns
PhoneID |PhoneNumber| Callstarttime| CallEndtime|
1 |111-111-1111|2013-04-01 05:13:03.000|2013-04-01 05:13:03.000
1 |222-222-2222|2013-04-01 05:15:12.000|2013-04-01 05:16:52.000
2 |333-333-3333|2013-04-01 05:17:29.000|2013-04-01 05:24:08.000
2 |444-444-4444|2013-04-01 05:21:50.000|2013-04-01 05:22:31.000
2 |555-555-5555|2013-04-01 05:22:41.000|2013-04-01 05:23:11.000
2 |666-666-6666|2013-04-01 05:23:20.000|2013-04-01 05:23:46.000

1. PhoneID is nothing but the participant in the call. PhoneID = 1 is twice from above. Which means 2 particpants (Same call )with 2 numbers with their callstarttime and callendtime. Similarly for PhoneID =2, there are 4 participants. And the list goes on for a day and then for a month.
2. For example a phone call P1 with 2 participants is going on for a particular day. We should not consider the same phone call having 2 participants involved. So that the concurrency would be 2. We have to ignore that here.
3. Only to be considered is other Phone calls for that day. Lets say P1 having call with 2 participants, P2 having some 4 participants which fall in the time period of P1. Then we should consider P1 and P2 the common period
4. In order to find number of concurrent calls happened for a day basing on callstarttime and callendtime. What would be the query?
5. Should consider the Timeperiod or the bucket with 1 hour as the period.
6. A Phone Call P1, Phone Call P2, should have matching (common) time ( keeping all the scenarios) is required for this query.
Result for Concurrent calls for a day should be like below. Should get all the concurrent connections happened for a particular day.
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Jan-02-2015|04 to 05|5
Jan-02-2015|12 to 13|13
........
ii) So once the above is achieved.
Have to find the Maximum concurrent connections for day from the above.
For below Maximum Concurrent connections are '3'
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Hence the Result for Maximum Concurrent Connections would be
Date|TimePeriod/Bucket(hr part)|MaxConcurrentconnections|
Jan-01-2015|01 to 02|3
Jan-02-2015|12 to 13|13

Hi!
I'm trying to get the following query to work:
SELECT item.name AS name, t15.f167 AS start, t15.f168 AS end, t15.f180 AS organizer
FROM item, t15
WHERE item.row_id = t15.id AND t15.f167 > getDate()
UNION ALL
SELECT item.name AS name, t30.f221 AS start, t30.f222 AS end, '<a class=kalender_link href=http://www.xxx.no/default.asp?V_ITEM_ID=' + item.id
+ '> KAN < / a > '
FROM item, t30
WHERE item.row_id = t30.id AND t30.f221 > getDate()
ORDER BY start DESC
The problem is the organizer field. I need to generate an url, but I get all sorts of problems with data types, ie. you can convert an int into ntext.
So the question is basically, how do I get the following to work:
'<a class=kalender_link href=http://www.xxx.no/default.asp?V_ITEM_ID=' + item.id + '> KAN < / a >'

I have a sql statement with 2 SELECT statements combined with the keyword UNION. Something like this
SELECT a, b
FROM ... WHERE ...
UNION
SELECT c, d
FROM ... WHERE ...
If i execute this in the Query Analizer everything works fine and i get the results. But if i execute this through Visual Basic (with database.OpenRecordSet(sql) ) i get following error message:
The Microsoft Jet database engine cannot find the input table or query .... Make sure it exists and that its name is spelled correctly.
If i execute the first part of this combined query in VB (e.g. SELECT a, b FROM ... WHERE ...), no errors occur. The same with the second part.
I find it really strange and any hints and tips are welcome!
thanks in advance.
When I run the following query with a UNION:
SELECT dbo.TBLCCINFORMATIONOCTOBER04.NAME, dbo.TBLCCINFORMATIONOCTOBER04.TITLE, LOWFARE, ITPSG.TBLCCONLINETOOL.AMOUNT as PRICE, 15 AS Lostsavings, LEFT(dbo.TBLCCINFORMATIONOCTOBER04.CostCtr, 4) AS COMPANYCODE, ITPSG.TBLCCONLINETOOL.InYear, ITPSG.TBLCCONLINETOOL.InMonth, 'TRADITIONAL BOOKING' AS Reason FROM ITPSG.TBLCCONLINETOOL INNER JOIN dbo.TBLCCINFORMATIONOCTOBER04 ON ITPSG.TBLCCONLINETOOL.AWID = dbo.TBLCCINFORMATIONOCTOBER04.AWID AND ITPSG.TBLCCONLINETOOL.InMonth = dbo.TBLCCINFORMATIONOCTOBER04.COLMONTH INNER JOIN dbo.TBLMONTHVALUE ON dbo.TBLCCINFORMATIONOCTOBER04.COLMONTH = dbo.TBLMONTHVALUE.monthname WHERE LEFT(dbo.TBLCCINFORMATIONOCTOBER04.CostCtr, 4) = '1038' AND INYEAR = '2004'AND InMonth = 'OCTOBER' AND (ITPSG.TBLCCONLINETOOL.DESTINATION = 'DOMESTIC') AND (ITPSG.TBLCCONLINETOOL.TYPE = 'TRADITIONAL') UNION SELECT dbo.TBLCCINFORMATIONOCTOBER04.NAME, dbo.TBLCCINFORMATIONOCTOBER04.TITLE, LOWFARE, ITPSG.TBLCCEXCEPTIONS.PRICE as PRICE, ITPSG.TBLCCEXCEPTIONS.Lostsavings AS Lostsavings, LEFT(dbo.TBLCCINFORMATIONOCTOBER04.CostCtr, 4) AS COMPANYCODE, ITPSG.TBLCCEXCEPTIONS.InYear, ITPSG.TBLCCEXCEPTIONS.InMonth, ITPSG.TBLCCEXCEPTIONS.Reason FROM ITPSG.TBLCCEXCEPTIONS INNER JOIN dbo.TBLCCINFORMATIONOCTOBER04 ON ITPSG.TBLCCEXCEPTIONS.AWID = dbo.TBLCCINFORMATIONOCTOBER04.AWID AND ITPSG.TBLCCEXCEPTIONS.InMonth = dbo.TBLCCINFORMATIONOCTOBER04.COLMONTH INNER JOIN dbo.TBLMONTHVALUE ON dbo.TBLCCINFORMATIONOCTOBER04.COLMONTH = dbo.TBLMONTHVALUE.monthname WHERE (LEFT(dbo.TBLCCINFORMATIONOCTOBER04.CostCtr, 4) = '1038') AND (ITPSG.TBLCCEXCEPTIONS.InYear = '2004') AND (ITPSG.TBLCCEXCEPTIONS.InMonth = 'OCTOBER') ORDER BY Reason
It returns these 16 records, 10 from the 1st table and 6 from the second. If I just remove the UNION operator and run them seperatly I get 11 from the 1st table and 6 from the second.
The record I am losing is the second of these two, but with the fields I am selecting they appear identical:
R,JosephField Operations Director INULL267.00001510382004octoberTRADITIONAL BOOKING
R,JosephField Operations Director INULL267.00001510382004octoberTRADITIONAL BOOKING
Is there any reason why the UNION statement is making that second record vanish? Is there a way I can alter the statement so I can run the query with the UNION and not lose records?
Thanks,
Guys can you tell me whether there is any difference between the following queries.......... Both of them are resulting same number of records. Not sure whether the output is same or not. Just wanted to know if result output wise if there is no difference than performance wise there might be some. Kinldy educate me on the same.
SELECT * FROM FRProposalOutline FPO
INNER JOIN SC_Collection SCC
ON
FPO.Items= SCC.CollectionGID
UNION
SELECT * FROM FRProposalOutline FPO
INNER JOIN SC_Collection SCC
ON
FPO.PageBreakPositions= SCC.CollectionGID
SELECT * FROM FRProposalOutline FPO
INNER JOIN SC_Collection SCC
ON
FPO.Items= SCC.CollectionGID OR
FPO.PageBreakPositions= SCC.CollectionGID

I need to all user IDs where the users have 3 permissions which are in a table holding about 100 different permissions
I need to find the user IDs like I do below but somehow have all three in the WHERE clause (I guess? but this does not work)
SELECT employees.employeeID FROM employees INNER JOIN employeePermissions ON employees.employeeID = employeePermissions.EmployeeID
AND employeePermissions.PermissionID = 'PROJECT_VIEW_ALL'
AND employeePermissions.PermissionID = 'PROJECT_MODIFY'
employeePermissions.PermissionID = 'PROJECT_DELETE'
the Permissions table has an EmployeeID column and a PermissionID column(which holds the permission name)
PLEASE HELP.
Thanks.
