1) tblT_Documents is the primary parent transaction table that has 10
fields and about 250,000 rows
2) There are 9 child tables with each having 3 fields each, their own
PK; the FK back to the parent table; and the unique data for that
table. There is a one to many relation between the parent and each of
the 9 child rows. Each child table has between 100,000 and 300,000
rows.
3) There are indexes on every field of the child tables (though I
don't believe that they are helping in this situation)
4) The client needs to be presented a view that has 5 of the main
fields from the parent table, along with any and all corresponding
data from the child tables.
5) The client will select this view by doing some pattern-matching
search on one of the child records' detail (e.g. field-name LIKE
%search-item% - so much for the indexes...)
Problem:
When I do the simple join of just the parent with one of the children,
the search works *fairly* well and returns the five parent fields and
the corresponding matching child field.
However, as soon as I add any one of the other child records to simply
display it's unique data along with the previously obtained results,
the resulting query hangs.
Is the overall structure of the tables not conducive to this kind of
query? Is this a situation where de-normalization will be required to
obtain the desired results? Or, more hopefully, am I just an idiot
and there is some simpler solution to this problem?!
Until today, I was always under the impression that left vs. right was determined by which side of the comparison operator the table was located.
In other words: LEFT JOIN LeftTable.ID = RightTable.ID
would pull all the records from LeftTable and those that matched from from RightTable and that:
RIGHT JOIN RightTable.ID = LeftTable.ID
would pull exactly the same result set but I was wrong. So, if it is not the table position in relation to the comparison operator, is it simply that the tables listed first in the FROM clause aren the ones "Left" of those subsequently entered?
I'm trying, with little success, to achieve something that should be quite easy (I think!) and any advice would be appreciated.
I have a leagues table structured so:
LeagueID | Name | Player1 | Player 2 ... Player6
and the data in the player columns is a userid from the users table and I'm trying to display the Leagues but with the player names rather than player IDs.
I'm working along the lines of
Code:
select u1.displayname as Player1, u2.displayname as Player2 from DCMLeagues as L inner join Users as u1 on L.player1 = u1.userid inner join Users as u2 on L.player2 = u2.userid
but with little success so far. Any thoughts would be appreciated! Thanks very much in advance.
I'm new to SQL 2005 & C# - I'm a MySQL/PHP crossover.
I'm using s Stored Procedure and I'm trying to do multiple joins onto one table. I have 6 fields in one table that are foreign keys of another table:
Table1
---------
id
PrimaryCode
SecondaryCode1
SecondaryCode2
SecondaryCode3
SecondaryCode4
SecondaryCode5
Table 2
---------
id
Title
CommCode
The fields in table 1 (except is obviously) hold the id of a row in Table 2. When displaying data I want to display "Title" - "CommCode" for each item in Table 1. I got myself started by searchig on the net and I have a stored procedure. The obvious problem is that as it goes through the Query only the last value remains in place - since each value before it is cleared in the UNION. How can I do this?? Here's my Stored Procedure:

I’ve never written a query with multiple APPLY joins before and I’m running into some troubles with my first one. The below SQL statement runs within 10 seconds if I comment out either one of the APPLY joins and its corresponding field columns. However, when I try to execute with both APPLY joins, the query runs indefinitely. The longest I’ve waited before cancelling it is 90 minutes.
Now, I know there are probably other ways I could write this query to get me the results I’m looking for. I’m posting this on the board because I’m curious about finding out why multiple APPLY joins could cause SQL Server to run away. I’m hoping to gain some insight so that I can better understand how APPLY joins work so that in case I have a big need to do this again in the future (without suitable workarounds) I can code it correctly.
Here are some things I’ve tried so far…
1.Changed the States table into a subquery that only returns a single state 2.Change all the references inside the APPLY subqueries so that they had different aliases (just in case they were conflicting with each other). 3.Changed the CROSS applies to OUTER applies. States has 50 records and only 32 have matching permit data so the 18 extra iterations using OUTER APPLY don’t impact performance any when an APPLY is used by itself.
SELECT s.state_name , COUNT(DISTINCT DUPS.PermitNumber) AS NumOfDupPermits , SUM(DistinctPermits) AS DistinctPermits FROM States S CROSS APPLY (SELECT w.StateID, COUNT(*) as DistinctPermits
I have a quite unusual problem, and I have hard time finding the answer.
I have a table with Locations - lets say that it has just ID, and Name, and a Transport table containing the ID, ArrivalLocationID and DepartureLocationID.
Now - when I select the Transport table I want to get names of the Arrival and Departure locations from th other table.
If it was a single link I woul do an INNER JOIN like:
SELECT Transport.*, Locations.Name AS ArrivalLocation FROM TransportProductOperationPeriods INNER JOIN Locations ON Transport.ArrivalLocation = Locations.ID
But I want to do a double INNER JOIN between two same table. And here I get a problem - how to do it? Something like:
SELECT TransportProductOperationPeriods.*, Locations.Name AS LArrivalLocation, Locations.Name AS LDepartureLocation, Locations.ID AS LArrivalLocationID, Locations.ID AS LDepartureLocationID FROM TransportProductOperationPeriods INNER JOIN Locations ON TransportProductOperationPeriods.ArrivalLocation = LArrivalLocationID INNER JOIN Locations ON TransportProductOperationPeriods.DepartureLocation = LDepartureLocationID
Hi,I'm having problems constructing a nested join. It's quite complex, sohere's a simplfied example of the problem. Any thoughts on what I'mdoig wrong - or if I've got the whole approach wrong are welcome.I've two tables :-one is a contact table contacting name, addresses etc. Three of thefields represent users - 'created by', 'last modified by' and 'owner'.They contain usernames - eg. JDOE, BSMITH etc.The other table contants usernames and new ID codes.What I want to do is create a new dataset by joining the contacts tablewith the user table on all three fields - so the new dataset containsthe ids for the creator, last modifier and owner.I've tried things similar to:select c.*, u1.id, u2,id, u3.idfrom contact cleft outer join users u1left outer join users u2left outer join users u3on (u3.username = c.owner)on (u2.username = c.modified)on (u1.username = c.creator )But it compains that"The column prefix 'c' does not match with a table name or alias nameused in the query."The problem is referencing c (contact) through the whole set of joins.I would like to do this in some similar format as the query is within acursor and post-processing would be very long-winded.Thanks
Each one of the tables listed below has a “CreateDateTime” and “UpdateDateTime” fields, I need to get yesterday changes, I can get any record where either CreateDateTime or UpdateDateTime is greater than midnight yesterday butI need to watch dates on all of the tables so I need to do atleast 10 date checks.
If any table shows an updated or created record, I need to gather ALL of the information for that customer. So, if my name didn’t change (SCUS table), but my email does (SEML table), I have to pull out both the SCUS and SEML tables (and the others, of course). So It may not be simple WHERE clause, How can I achieve this:
I am wondering if tempdb stores all results tempararily whenever I query a large fact table with over 4 million records which joins another dimension table? Since each time when I run the query, the tempdb grows to nearly 1GB which nearly runs out all the space on my local system drive, as a result the performance totally down. Is there any way to fix this problem? Thanks a lot in advance and I am looking forward to hearing from you shortly for your kind advices.
I'm trying to write a 3 table query using two LEFT JOINs. Originally, I only had one LEFT JOIN and prior to the addition of the the third table (parts) this query worked. Now it doesn't. I think it has to do with my GROUP BY.
SELECT quote.quote_id, parts.material, machining_operations.machine, machining_operations.per_roughing, machining_operations.per_of_machining, machining_operations.programming_time, machining_operations.setup_time, machining_operations.cycle_time, machining_operations.notes quote.part_name, quote.revision_no, quote.quantity, quote.initial_volume, quote.final_volume, quote.material_price, machining_operations.mo_id FROM quote LEFT JOIN machining_operations ON machining_operations.quote_num = quote.quote_id LEFT JOIN parts ON parts.package_no = quote.package_no AND parts.part_name = quote.part_name GROUP BY quote.quote_id
Table structure is very simple as below and I know there are solutions with joins (Left outer joins), need to know if it is possible to get o/p without using joins
Note:- also need records who doesn't have manager (null)
I have a table which visibility can be toggled by a text box. By default it is invisible. After it is made visible, clicking a sortable column header makes the table invisible. Does this mean sorting makes the table go back to its default visibility?
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

I need to create a view which links 5 tables as follows: I have a Header Table which is keyed on Product and Year which I want to join to a Detail Table which is keyed on Product and Year and Week. I want to see all of the rows from each table, which I think is a FULL OUTER JOIN.
I then have three subsidiary tables for Sales, Orders and Deliveries which are all keyed on Product and Year and Week - I want to join each of these tables separately to the Detail table above so that again I see all of the rows from the Detail Table, the Sales Table, the Orders Table and the Deliveries table. For any Product/YearWeek there may or may not be a row on any of the Sales, Order or Deliveries table, but there will not be any rows on these tables which are not on the Detail Table.
Can I do this in the FROM clause andnif so how, or do I need to do a series of separate SELECTs for the Sales, Orders & Deliveries table with UNION clauses. Best regards Colin
Application called Filemaker, I'm now trying to use that experience to teach myself SQL (using Microsoft SQL is SQL 2008 r2).My question is can you have multiple self joins.
I have a table which has two columns (for this example)
spell | spellindicator | episode
the spell is not unique e.g. there could be several records with the spell 'A1234' the spellindicator column will contain a number 1 or 2. the data could look like this:
Part 1) works fine on its own Part 2) works fine on its own
But put both joins in the same statement and the count function no longer works correctly. I realise that there is an issue with the self joins but I thought it would be possible to have multiple self joins.
use leis go select l1.spell, l1.spellindicator, l1.episode, l1.pk_Indicator, l1.fk_indicator ,maxepisode = MAX(e2.episode) ,minepisode = MIN(e2.episode)
I have a customer table which has customer billing addresses; an orders table which has payment and shipping method info; and an items table which has line items for each order. The customer table has a custnum index field. The orders table has a custnum and orderid field. And the items table has an orderid field.
I'd like to be able to retrieve, in one query, the customer's billing address, all of their orders, with each of their order's line items.
What would the query look like in order to accomplish this?

Any help would be greatly appreciated!
I'm putting together the site for a local darts league, essentially each of the teams completes an 'e-scorecard' for that particular game. This is then stored in a table named 'scorecardIndex' :
So each 'index' points off to the UID of the player who was captain, and the UID of of each team.
What I'm struggling with is joining this all together, as I'm joining both scxTeam1Capt and scxTeam2Capt to the same columns in the 'players' table (plFirstName, plSurname)
Could somebody tell me what is the secret of being able to write a SELECT statement having mulitple LEFT or RIGHT joins, I seem to get in trouble as soon as I add the second LEFT join, as I am obviously doing it wrong.
These are my tables, would somebody mind having a go,or explaining what do i need to be aware of in a case like this
with cte1 as (select siteid ,productcategory ,sum(isnull(netsales,0)) as netsales from dbo.vw_sv_invoicedetail where invoicedate>=dateadd(dd,-90,getdate())

I need to add routeid column so that i can finally display sum of sales grouped by routeid in addition to the siteid that i am already displaying.
I have a general question concerning joins. Below is a table scenario:
SELECT * FROM TABLE_A T0 INNER JOIN TABLE_B T1 ON T1.[Some_Column] = T0.[Some Column] LEFT JOIN TABLE_C T2 ON T2.[Some_Column] = T0.[Some Column]
Does the above indicate that all records in common between TABLE_A & TABLE_B will be returned, then the records from TABLE_C will be joined to the initial 'result set' (that is the result of joining TABLE_A & TABLE_B), or will TABLE_C simply be joined to TABLE_A regardless of the inner join between TABLE_A & TABLE_B?
Hi I have a requirement where in i haev to convert the SQL from Oracleto the one which will run on the SQL server.in the Oracle Query i am doing multiple joins, between some 13 tables.and some of these joins are inner joins and some are Left outer joins.table1 inner joined with table 2table2 inner join with table3table2 inner join with table4table2 left join with table5table5 left jin with table6table6 left jin with table7table7 left jin with table8table8 left jin with table9Any idea how to achieve this??Tianaren
Hi All Database Gurus,I am trying to write code which will produce all the possible validqueries, given tables and join information for tables.Right now i am just trying to construct all the sequential joins.eg. if i have 4 tables A, B, C, D and the join conditions areA Inner join B,B Inner Join C,C Left Outer join Dthen i am constructing joins as :1. A IJ B IJ C LJ D2. B IJ A IJ C LJ D3. B IJ C IJ A LJ D4. B IJ C LJ D IJ A5. C IJ B IJ A LJ D6. C IJ B LJ D IJ A7. C LJ D IJ B IJ AI am not placing any paranthesis to specify the join order. And manyof them are giving me same output.Can anybody tell me how to detect the joins which will give the sameoutput ?here in this case the number of combinations are 7 but for 8 tables iam getting 420 combinations and many of them are same.so please help me to reduce the number of combinations.eagerly waiting for suggetions.Thanking you.Prem.(premratan@hotmail.com)
I want to create a dynamic merge filter on a table but the data I filter on is only reachable by a few extra joins. For example:
I want to filter Table3. Table3 is joined to Table2 which in joined to Table1. Table1 contains the host_name column that I use to filter i.e. host_name = HOSTNAME().
In order to get filtered data in Table3 do I have to also filter Table 2 and Table1, or in my filter clause for Table3 can I say something like: Table3.FKid = Table2.Id and Table2.FKId = Table1.Id and Table1.host_name = HOSTNAME()?
I'm pretty sure I can't use AND in my dynamic filter clause but I just wanted to make sure.
Hi,I am written a store procedure that would access four tables and grab appropriate fields.. I am using JOIN functionality because it can have multiple rows.
