SQL Server 2014 :: Union All Statement Hangs Engine?
Sep 9, 2014
I have TSQL query using UNION ALL. First subset returns 92 rows, second subset return 0 (ZERO) rows. Now if I execute them separately they execute subsecond. If I put UNION ALL between them then it hangs forever exactly on 88s row.
I understand I need to provide execution plans, actual queries etc but before going into all this details, why on earth even in theory UNION ALL with empty result will result in a hang of the first subset?
Based on estimated execution plan 2 subqueries are performed in parallel and then CONCATENTION is being used which shall result with just first subset immediately displayed in result.
Estimated execution plan attached, I can not get actual execution plan because query never completes.

During installation of MSDE the installation hangs at "please wait while Windows configures microsoft sql server desktop engine" I always end up killing the installation process. I am trying to install Windows XPe dev kit and this is the step I am getting stuck on. If I try to skip this step and setup the database the setup obviously tells me that i dont have sql 200 or MSDE installed.
The KB article http://support.microsoft.com/kb/811479 describes the syptoms perfectly, but fast user switching isnt even enabled for this machine and is not the source of the problem.

I have a performance issue with one of the views when I join the view with a temp table
I have 2 Views - View1 and View2.
There is a third view - view_UNION where the
view_UNION =
SELECT * FROM View1
UNION ALL
SELECT * FROM View2
If I have a query like -
Select view_UNION.* FROM
view_UNION INNER JOIN #TMP ON #TMP.ID = view_UNION.ID
the execution is too slow.
But if I execute the views separately, I get good performance.
How to improve the performance of the view_Union

We have a table with 500+ columns. The data is non-normalized, i.e. there are four groups of fields for for "people", followed by data that applies to all people in the row (a "household").For ad-hoc queries, and because I wanted to index columns within each person (person 1's age, person 2's age, etc.), I used UNION:
SELECT P1Firstname AS FirstName, P1LastName as LastName, P1birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns>
UNION
SELECT P2Firstname AS FirstName, P2LastName as LastName, P2birthday AS birthday, HouseholdIncome, HouseholdNumber of Children, <other "household" columns>
I could get at least the P1... P2... P3... columns with PIVOT, but then I believe I'd have to JOIN back to the row anyway for the "household" columns. Performance of UNION good, but another person here chose to use PIVOT instead.I can' find any articles on PIVOT vs. UNION for "de-flattening".

I have a query. Here are the steps:
1. I created a maintenance plan using Visual Studio 2013 (nothing fancy pretty basic)
2. Using ssms 2014 I imported it (the dtsx file) under the Integration Services and it appeared there successfully
3. I connected to the Database Engine again using ssms 2014 - my expectation was to see it under the Management > Maintenance Plans folder but it was not present.

I am trying to run a UNION ALL query in SQL SERVER 2014 on multiple large CSV files - the result of which i want to get into a table in SQL Server. below is the query which works in MSAccess but not on SQL Server 2014:
SELECT * INTO tbl_ALLCOMBINED FROM OPENROWSET
(
'Microsoft.JET.OLEDB.4.0' , 'Text;Database=D:DownloadsCSV;HDR=YES',
'SELECT t.*, (substring(t.[week],3,4))*1 as iYEAR,
''SPAIN'' as [sCOUNTRY], ''EURO'' as [sCHAR],
[Code] ....
What i need is:
1] to create the resultant tbl_ALLCOMBINED table
2] transform this table using PIVOT command with following transformation as shown below:
PAGEFIELD: set on Level = 'Item'
COLUMNFIELD: Sale_Week (showing 1 to 52 numbers for columns)
ROWFIELD: sCOUNTRY, sCHAR, CATEGORY, MANUFACTURER, BRAND, DESCRIPTION, EAN (in this order)
DATAFIELD: 'Sale Value with Innovation'
3] Can the transformed form show columnfields >255 columns i.e. if i want to show all KPI values in datafield?
P.S: the CSV's contain the same number of columns and datatype but the columns are >100, so i dont think it will be feasible to use a stored proc to create a table specifying that number of columns.

I have two tables for insertion in one transaction scope. Table one have 10 rows. After first table insert statement (not yet committed) if I run select on first table from other session, it holds table until my insert is committed or rolled back and from (SSMS), it display 10 rows and then wait for transaction scope till finished. My question is do I need to use no lock hint in this situation. Or there is something wrong with isolation level. One saying that in this situation table should not hols select while insert is in transaction scope.

SQL Version - SQL Server 2005 Standard Edition, SP 1
I have a database which is Broker Enabled. We use Query notification extensively and the application is in testing stage. Both Testing and development database is on the same server. When I create database for testing I used to do Backup-restore method. When i restore a borker enabled database, the restored database and the source database will have same GUID for Broker. So by default the restored database will not be broker enabled. So what I do is , i run
Alter database somedatabase SET NEW_BROKER.
This statement will generate new GUID for this database and then we can enable the Broker by SET ENABLE_BROKER statement. Till last week this process was working fine. When I did the same thing yesterday the Alter database somedatabase SET NEW_BROKER query was runing for whole night and it could not complete the process.
What SET NEW_BROKER internally does as per BOL is
NEW_BROKER
Specifies that the database should receive a new broker identifier. Because the database is considered to be a new service broker, all existing conversations in the database are immediately removed without producing end dialog messages.
When I checked the Conversation in the database there were millions of rows.
My question is , can I do the same process in a better way and how. Is there any way to clear Conversation in a faster method. I googled , but I could not find a better solution.

Here's my statement below. What I'm trying to get is joining the name column in master.sys.databases with a sub query for the database name, file location and backup start date from the MSDB database. The reason for this, if a new database has never been backed up, It should be returning as a NULL value, which is my goal. However, I'm getting multiple results for the backups.
select CONVERT(CHAR(100), SERVERPROPERTY('Servername')) AS Server,a.name,File_Location=b.physical_device_name,backup_start_date=max(backup_start_date)
from master.sys.databases a
left join(select c.database_name,backup_start_date=max(backup_start_date),b.physical_device_name
from msdb.dbo.backupmediafamily b join msdb.dbo.backupset c on c.media_set_id=c.backup_set_id
where c.type='D'

I have 3 tables One table is the order Table, Bill to table and ship to table
I have to Views created as followed
This query uses the Ship to table to pull the ship to information to the shipping system.
SELECT Cust_address.NAME, Cust_address.ADDR_1, Cust_address.ADDR_2, Cust_address.ADDR_3, Cust_address.CITY, Cust_address.STATE, Cust_address.ZIPCODE, Cust_address.COUNTRY, Cust_address.SHIP_VIA, customer_order.ID
FROM Cust_address INNER JOIN customer_order ON (Cust_address.CUSTOMER_ID = customer_order.CUSTOMER_ID) AND (Cust_address.ADDR_NO = customer_order.SHIP_TO_ADDR_NO);
This query uss the Bill to as the ship to inforamtion
SELECT CUSTOMER.ID, CUSTOMER.SHIPTO_ID, CUSTOMER.NAME, CUSTOMER.ADDR_1, CUSTOMER.ADDR_2, CUSTOMER.ADDR_3, CUSTOMER.CITY, CUSTOMER.STATE, CUSTOMER.ZIPCODE, CUSTOMER.COUNTRY, CUSTOMER.SHIP_VIA, customer_order.ID, customer_order.SHIP_TO_ADDR_NO
FROM CUSTOMER INNER JOIN customer_order ON CUSTOMER.ID = customer_order.CUSTOMER_ID;
I need this infroamtion in one table which I have done in the UNION statement as followed:
SELECT Cust_address.NAME, Cust_address.ADDR_1, Cust_address.ADDR_2, Cust_address.ADDR_3, Cust_address.CITY, Cust_address.STATE, Cust_address.ZIPCODE, Cust_address.COUNTRY, Cust_address.SHIP_VIA, customer_order.ID
FROM Cust_address INNER JOIN customer_order ON (Cust_address.CUSTOMER_ID = customer_order.CUSTOMER_ID) AND (Cust_address.ADDR_NO = customer_order.SHIP_TO_ADDR_NO)
UNION ALL
SELECT CUSTOMER.NAME, CUSTOMER.ADDR_1, CUSTOMER.ADDR_2, CUSTOMER.ADDR_3, CUSTOMER.CITY, CUSTOMER.STATE, CUSTOMER.ZIPCODE, CUSTOMER.COUNTRY, CUSTOMER.SHIP_VIA, customer_order.ID
FROM CUSTOMER INNER JOIN customer_order ON CUSTOMER.ID=customer_order.CUSTOMER_ID;
Here is the problem when I pull information out of the ship to table I get 2 results as followed My key field to pull this information is the Last field Custoemr ID this custoemr ID exist in both tables but contains different information I want to ONLY pull in the info that I need in this case it would be the first line that is the Correct shipping information.

I am not completly sure if I have this posted in the right forum so if I don't just let me know and I will move it. Here is my problem. I need to be able to use the WHERE keyword more than once in one SELECT statement and have not been able to figure this out. I need to be able to first search for information under one column with the WHERE keyword like usual and then I need to be able to search the returned results with another WHERE keyword to narrow down the returned results. I tried writing two SELECT statements and joining them with a UNION ALL keyword like this:
"SELECT LI.ID, LI.CNID, CD.ID, LI.FDName, LI.FDR " & _
"FROM FinalDrive AS LI INNER JOIN CarData AS CD " & _
"ON LI.CNID = CD.ID WHERE LI.CNID = '1'" & _
"UNION ALL" & _
"SELECT LI.ID, LI.CNID, CD.ID, LI.FDName, LI.FDR " & _
"FROM FinalDrive AS LI INNER JOIN CarData AS CD " & _
"ON LI.CNID = CD.ID WHERE LI.FDName = 'Car1"
This hasn't worked and I didn't expect it to. Everytime I run this code I get an Unhandled SqlExecption:
Invalid column name 'Towing'.
Can anyone help me with figuring out how to use the WHERE keyword more than once. I am using Visual Basic.Net with ADO.Net. Thanks!

I have a report that is using a union statement to pull in data from two identical tables except that one is for current month, the other for archived data.
What I want to do is prompt the user once for a date and use the value to select from the right table. Since a sales date can only exist in one of the tables, one union will work, the other not.
But the report in prompting me for a parameter for each query....which is in Informix and the prompt is this: "?"
Is there anyway to force both halves of the query to see this as one parameter so the user is only prompted once?
Thanks

Hi,
I'm trying to write a UNION statement with 2 selects and can't figure out for the life of me how to do it.
select top 10 * from tblusers ORDER BY dateJoined
UNION
select top 10 * from tblusers ORDER BY lastLogin
The union works fine without the order by's, but I really need the order by's in there and I don't understand why its so difficult to do. Surely there must be some other strategy?
Any help is much appreciated.. thanks!!

now i want to ad a limit to this statement, but i can't get it working. i have tried this:SELECT * FROM (SELECT [Name], [EventID] AS [ItemID], [TourID], [Date], NULL AS [StartDate], [Date] AS [SortDate], [Type] FROM [Events] WHERE [TourID] IS NULL AND AccessLevel <= @AuthenticationLevel UNION SELECT [Name], [TourID] AS [ItemID], [TourID], NULL AS [Date], [StartDate], [StartDate] AS [SortDate], '2' AS [Type] FROM [Tours]WHERE AccessLevel <= @AuthenticationLevel) ORDER BY [SortDate] LIMIT 2
but i keep getting an error message saying "Incorrect syntax near the keyword "ORDER". what am i doing wrong?

Hi,I have a database stored in MS SQL 2000 and an application written inVB5, which connects the database via JET/ODBC.I have a problem with the UNION statement.When I run a simple query like:"SELECT field1 FROM table1 UNION SELECT field2 FROM table2"I get the following error:"Runtime error 3078 - The Microsoft Jet database engine cannot find theinput table or query 'select field1 from table1'. Make sure it existsand that its name is spelled correctly."I can run the queries separately "SELECT field1 FROM table1" and "SELECTfield1 FROM table2", so that I'm sure table and field names are correctand I have permission to access them.Both field1 and field2 are the same type (int).If I run the query in MS SQL Query Analyzer, it works fine.It doesn't work only when I run it from VB/JET/ODBC.Has anyone already had this kind of problem?Any help will be highly appreciated!Thank you so much for the attention.--Posted via http://dbforums.com

Hi,Should be quite simple but can someone please tell me the best way tocount the number of rows in an UNION ALL statement.I tried using @@ROWCOUNT but that doesn't seem to contain the correctnumber.Also, I assume that running the query again but just returning count(*)instead of the data is horribly inefficient (plus the code is thenbloated.)?Thanks,Mark

I am trying to use SQL to pull unique records from a large table. The table consists of people with in and out dates. Some people have duplicate entries with the same IN and OUT dates, others have duplicate IN dates but sometimes are missing an OUT date, and some don’t have an IN date but have an OUT date.
What I need to do is pull a report of all Unique Names with Unique IN and OUT dates (and not pull duplicate IN and OUT dates based on the Name).
I have tried 2 statements:
#1:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
GROUP BY tblTable1.Name, tblTable1.INDate
ORDER BY tblTable1.Name;
#2:
SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#))
UNION SELECT DISTINCT tblTable1.Name, tblTable1.INDate
FROM tblTable1
WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#));
Both of these work great… until I the OUT date. Once it starts to pull the outdate, it also pulls all those who have a duplicate IN date but the OUT date is missing.
Example:
NameINOUT
John Smith1/1/20141/2/2014
John Smith1/1/2014(blank)
I am very new to SQL and I am pretty sure I am missing something very simple… Is there a statement that can filter to ensure no duplicates appear on the query?

I have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName
I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated!
Thanks,
Randy
