How can I achieve the same effect as a cross join (since the merge operator doesn't have a cross join)?
Situation is this... a flat file has some header and footer information that I need to keep and attach to each row. So for simplicity sake of an example lets just say header has only 1 thing we care about - a row that says DATE=01/01/06.
I take the file and run a split to split into "Date" "Data" and "other" (other has all the throwaway rows in header and footer I don't care about). Then I use a derived column object to get all the columns out of the "Data". Finally I want to add that Date metadata back to every row in the data...
I thought this would be an easy thing to do.. but I can't seem to figure out how to duplicate that Date info into every row.. Hopefully I am overlooking something simple.
If I have three large tables to join together should I join the two that I know will cut the number of rows down a lot first and then join the 3rd table or does it make no difference (if I join the first and 3rd - which I know will be a large result set and then join the 2nd).
I have the following structure with remote select permissions; I cannot create temp tables or use stored procs:
tblEvent with event_pk, eventName tblReg with reg_pk, event_fk, person_fk, organization_fk
I'm currently using a case statement to get counts for these categories: case when c.person_fk is Null and c.organization_fk is not null then 'Employer' when c.person_fk is Not Null and c.organization_fk is null then 'Individual' when c.person_fk is not Null and c.organization_fk is not null then 'Both' else 'Unknown' end
But I need some kind of count (0) for every category. I've used a cross-join, group by in the past - but what do you do if you don't have a table? For example, the end result when selecting event_pk=(112,113) would be:
I am wanting to show Total Quantity of Presentations2 for each EmpVol and TypeofPresentation, even if there are no Presentations done in TypeofPresentation or if an Employee did not do any Presentations.
I am close with the query below - but not getting back exactly what I want - Ideas.
SELECT ISNULL(Presentations2.Quantity, 0) AS Quantity, TypeofPresentation.Typeofpresforrpt, EmpVol_2.LastName, EmpVol_2.FSSTVOLUNTEER FROM Presentations2 INNER JOIN EmpVol ON Presentations2.ID = EmpVol.ID RIGHT OUTER JOIN TypeofPresentation ON Presentations2.TypePresINT = TypeofPresentation.TypePresINT CROSS JOIN EmpVol AS EmpVol_1 CROSS JOIN EmpVol AS EmpVol_2 GROUP BY TypeofPresentation.Typeofpresforrpt, EmpVol_2.LastName, EmpVol_2.FSSTVOLUNTEER, ISNULL(Presentations2.Quantity, 0) HAVING (EmpVol_2.FSSTVOLUNTEER = N'FSST')

I have to retrieve a cross join between languages and language-skills for more person in a matrix (grid) report.
E.g. i like to ritrieve the TOP 2 people in each "cell" of the grid (order by name). There are 3 people in cell "ITALIAN / very good". So i have to retrieve only the top 2.
In table tEmployee i have the people names (john, anna, michael) In table tLanguage i have all language (english, italian, german) And in table tLanSkill i have the language rating (bad, good, very good)
I have the following tables:members--------------member_idmember_tpc_id ( = tpc.tpc_id)tpc------tpc_idcourse------------course_idtpc_assignment---------------------------tpc_assignment_idcourse_idenrollment-------------------member_idcourse_idenrollment_status Now I want to select all members where member_tpc_id>0 and get the enrollment_status of each member in each course where course_id IN (Select course_id From tpc_assignment)Now what i did was get all the members and then all the courses and did a cross join between them. There are about 1900 members and 80 courses and when I do a cross join I get 1900*80 rows (152000) and the status of each member for all the 80 courses. If not enrolled it returns Not Enrolled (i have a UDF which takes a member_id and a course_id and returns the status). The BIG problem is that its taking about 6-8 mins to run the query and as a result its timing out on the aspx page. Can someone please tell me how I can do what i am trying to do without using the cross join because I suspect its the culprit here. The query I came up with is Select *, dbo.returnStatus(temp1.user_id, temp2.course_id) As Status, (Select tpc_title From tpc Where tpc_id = temp1.member_tpc_id) As Tpc_Title From (Select member_id As user_id, member_name, member_tpc_id From members Where member_tpc_id> 0 And organization_id = '1' )temp1 cross join (Select course_id As course_id, course_title As course_title From course Where course_id IN (Select course_id From tpc_assignment Where tpc_requirement_id IN (Select tpc_requirement_id From tpc_requirement) And course_id<>0 And organization_id = '1') )temp2 Order By member_name, Tpc_TitlePlease help. Thank you.
Hello, I have a query that returned much more results than it should. I believe this is because it was a cross join instead of inner join (because I forgot to map a temporary relationship in the designer of SQL Server Express; I think this is what the problem may have been, but I can't remember), but could it be because the join criteria is because it is an nvarchar(MAX)? I did the join on two nvarchar(MAX) fields. The table has 31102 rows in both tables, and it would pull back the first entry in the first table, and all 31102 rows in the second table, and so it would pull back 31102 rows for each entry in the first table. Is that only because of the cross join, or maybe because of nvarchar(max)?
Hey All... Got a View question. Have 2 tables: #1 Currencies |CCY_Name|CCY_Code|
#2 Rates |CCY1|CCY2|CCY3|...etc|Active| -> where the Columns CCY# = the Records in #1
How do I build a View to Select the ONE record in #2 where Active=Y, having the CCY_Name from #1 based on #2.CCY1 (Column NAME) = #1.CCY_Code (Record).
I populate the first table with a litst of stores that offer all desired items.
I populate the second table with a list of vendors, the item is, and cost avaiable at each of the stores in the first table.
What I would like is to output all possible the store and vendor combos ordered by combined price.
So, for instance, I have 3 products, A B and C. Store X has A and B by vendor G, and A B and C by vendor H. I want the output to have all iterations of (Store, Product, Vendor, Price) grouped in order of total price. So...
X A G X B G X C H
X A G X B H X C H
X A H X B G X C H
X A H X B H X C H
ordered by each group's combined price.
For some reason, I can't get this straight in my head. Must need more coffee.
I need to pickup a tax rate, that is stored on a 1 record file. I would like to avoid using the CROSS JOIN. Is there a way to SELECT the record and set a Variable = to the tax rate so I can pickup the rate in another SELECT statement on each record?
I have information on clothes in a table that I want to select out to a result set in a different structure - I suspect that this will include some kind of pivot (or cross-join?) but as I've never done this before I'd appreciate any kind of help possible.
Current structure is:
Colour Size Quantity ----------------------- Red 10 100 Red 12 200 Red 14 300 Blue 10 400 Blue 12 500 Blue 14 600 Green 10 700 Green 12 800 Green 14 900 Green 16 1000
I want to produce this result set:
Colour Size10 Size12 Size14 Size16 ------------------------------------- Red 100 200 300 0 Blue 400 500 600 0 Green 700 800 900 1000
There could be any number of sizes or colours.
Is this possible? Can anyone give me any pointers?
I have two inline selects against a table with a nonclustered columnstore on SQL 2014 (12.0.2000). Both execute in batch mode and when I inner-join the two, they continue to execute in batch mode. When I cross join them, one executes in row mode. Below is some SQL to simulate the issue.
-- The purpose of this script is to demonstrate that -- two queries against a columnstore index that each execute in batch mode -- will continue to execute in batch mode when inner joined. -- However, one of the queries will execute in row mode when cross-joined.
-- Create function to return 0 to n rows IF OBJECT_ID('dbo.IntCount') IS NOT NULL DROP FUNCTION dbo.IntCount;
I have this stored procedure. I want to run a few simple SQL functions against my tables. In particular I want to take a subset of records (One or Two years worth) and calculate AVG, VAR and STDEV.
It does not work the way I thought it would. I end up with the whole input table in #tempor1 which is about 6 years worth of records.
set ANSI_NULLS ON set QUOTED_IDENTIFIER OFF
GO ALTER PROCEDURE [dbo].[findAve1YearDailyClose_MSFT] AS BEGIN SET NOCOUNT ON; SELECT adjClosed, volume INTO #tempor1 FROM dbo.dailyCl_MSFT GROUP BY dateTimed, adjClosed, volume HAVING (dateTimed > DATEADD (year, -1, MAX (dateTimed)))
SELECT AVG (adjClosed) AS "AVGAdjClose1Year", VAR (adjClosed) AS "VARAdjClose1Year", AVG (volume) AS "AVGVolume1Year", STDEV (volume) AS "STDEVVolume1Year", COUNT (*) AS "total" FROM #tempor1 END
Thus if I change the number of years I subtract from the latest date from 1 to 2 I end up with the same result. What is the problem?
What happens to these REPLication agents if SQL Agent is stopped and started: Snapshot Agents Merge Agents Misc Maintenance Agents
Can the agent be stopped and started with no thought to the status of replication, or should the replication state be modified in some way before any change to the status of the Agent?
(I know REPL depends on agent, so wuestion is, can REPL simply resume or not when agent is re-started.)
Does someone know if doing a reindex on a clustered or non-clustered index cause the snapshot file to grow? In other words, is the data that makes up the snapshot copied from the source to the snapshot database? If a normal reindex is done on the underlying database, will it block users from acessing the snapshot? Any help would be appreciated.
Select Query Left Join Select Query 2 Left Join Select Query 3
How does it work actually? As in, whether Query 2 & Query 3 will work only on the records retrieved by Query 1 only. Or, all the select statements retrieves all the records and then the condition is applied to filter out the results.
Also, does the order of the Select statements make any difference on the speed?
We have a database that we have designed so all the data dependances are managed by the front end code. However the company we are writing it for has asked us to add around 50 constraints. I was just a little worried what kind of effect on performance this would have. Cheers Ed
Edit: Sorry This is OSQL.What I use as my query is:"DELETE FROM timerecord WHERE Actual_Time_In LIKE '11.12.2006%'"The row of Actual_Time_In is formatted with Date and time (MM.DD.YYYY HH:MM:SS) sometimes there are ten records and I'd rather not have to remove them from the table one at a time. However, even though I have a record that is '11.12.2006 22:43:00' my delete doesn't work osql states I have 0 rows affected.This is only MSDE so I don't have anyother way to open the table.Sometimes these records have other records that reference them. Is there anyway to do a cascading delete without it getting to complex?Thanks of all your help, I am just a tech support guy beating his head against a wall..
Hello all, thanks in advance for any advice here. My question is, what's the effect of the Enterprise Manager > Tasks > Shrink Database function? It seems to reduce the used space on the device. Testing it on some dev machines, I've seem to have gotten back as much as 20g of space. I know it should grow back to that, but the time it took was minimal, and it didn't seem to affect my developers. They tend to add alot and delete alot during testing. What negative effects of running this should I look out for? Will it affect the DB long term? Is is preferable to schedule once a month or so? Is this done on Production DB's? Thanks for any guidence on the usage of this.
