I want to filter some search results using an inner join.
The criteria are passed as a parameter.
If the parameter has value, I want to inner join with it.
If there is a NULL value, I just want to ignore the inner join.
I don't want to:
1) Build a string and do an exec() - too slow and hard to maintain
2) use a (@parm IS NULL) OR ('inner join') AGAIN, too slow
Suggestions appreciated

I have a Problem with my destinations. I have a split condition with two ways the flow can use.
In this case: all and Date.
All and Date can be set by using a variable. Its working good.
When a user fills the variable with a date value (cast to string) the conditional split executes the correct flow with all the needed rows... The same time the all flow will be executed with 0 rows. In the end the destionation file for the all values will be overwritten with nothing. The same on the other hand when a user fills the variable with the all value, the date file is empty. What can i do to make sure that the files are not empty?
Im faced with the following design issue..
on my site there are different profiles: a city profile, a restaurant profile and a user profile.
in my DB:City profiles are stored in tbCities cityID int PK shortname nvarchar(50) forumID int FK (...)
Restaurant profiles are stored in tbRests restID int PK shortname nvarchar(50) forumID int FK (...)
User profiles are stored in tbUsers userID int PK shortname nvarchar(50) forumID int FK (...)
as you can see a single ID value (for CityID,restID or userid) might occur in multiple tables (e.g. ID 12 may exist in tbRests and in tbUsers)Each of these profile owners can start a forum on their profile.
forumID in each of the above tables is a FK to the PK in tbForums:forumID intforumname nvarchar(50) (...)
Now imagine the following:
a site visitor searches ALL forums...say he finds the following forums:ForumID Forumname1 you opinion on politics2 is there life in space?3 who should be the next president of the USA?
a user may want to click on the forum name to go to the profile the forum belongs to.And then there's a problem, because I dont know in which table I should look for the forum ID...OR I would have to scan all tables (tbCities,tbRests and tbUsers) for that specific forumid,which is time-consuming and I dont want that!
so if a user would click on forumID 2 (is there life in space?)
I want to do a conditional inner join for the tablecontainingforumID (which may be tbCities,tbRests or tbUsers)
select tablecontainingforumID.shortname FROM tablecontainingforumID tINNER JOIN tbForums f ON t.ForumID=f.ForumIDwhere f.ForumID=2
I hope my problem is clear..any suggestions are welcome (im even willing to change my DB design if that would increase effectivity)
I have three tables ...
tblWine tblSpecialOfferWine tblSpecialOffer
ID Name ID WineID SpecialOfferID ID Name IsLive
===================== ============================ ==========================
1 Mouton Rothschild 1 1 1 1 February Offer 0
2 Lafite Rothschild 2 1 2 2 March Offer 1
3 Chateau Teyssier 3 2 1
... and the current query I am using is the following along with it's result set ...
SELECT
tblWine.ID AS WineID,
tblWine.Name AS WineName,
tblSpecialOffer.ID AS SpecialOfferID,
tblSpecialOffer.Name AS SpecialOfferName
FROM
tblWine
LEFT OUTER JOIN tblSpecialOfferWine ON tblSpecialOfferWine.WineID = tblWine.ID

Results
WineID WineName SpecialOfferID SpecialOfferName
================================================== =========
1 Mouton Rothschild 1 February Offer
1 Mouton Rothschild 2 March Offer
2 Lafite Rothschild 1 February Offer
3 Chateau Teyssier NULL NULL
... but the result set I want is All wines and their associated specials offers but only show details of the offer if the offer is live like so ...
Results
WineID WineName SpecialOfferID SpecialOfferName
================================================== =========
1 Mouton Rothschild 2 March Offer
2 Lafite Rothschild NULL NULL
3 Chateau Teyssier NULL NULL
... I've tried putting where clauses like ...
WHERE tblSpecialOffer.IsLive = 1 OR tblSpecialOffer.IsLive IS NULL
... but then that hides the wines that were on a previously associated on a special offer but is no longer live (see Wine #2).
Any ideas on the query I should be using?
Note: The queries and data above were made off the top of my head so may contain mistakes.

option 2.if there is no record that matches option1 then, serch for the previous record with end_dt in table A less than end_dt table B. if there is more than one record then select lowest ID
option 3. if there is no record option 2 then search the next record that matches .. discharge_dt greater than end_Dt , if there is more than one record then select lowest Id
so basically, I am looking for an exact matching date in the same registration_key .. if the exact dt doesn't exist looking for the previous record and get the most closer dt and if there is no prvious record than look for next record,.
so the output should look like

Hello,
I want to write a query that joins data in a different table based on a column value. The table is for a "Playlist" and holds play list items. The items can be video, audio, images, etc. The playlist table looks like this:
Table_Playlist
-----------------
ID (int)
MediaType (char)
MediaId (int)
Table_Audio
-----------------
MediaId (int)
Table_Video
--------------
MediaId (int)
If the Table_Playlist.[MediaType] column value = "Audio" then I want to join to the Table_Audio table. If the value = "Video" then I need the video table.
Hope that makes sense. Thanks

I need to add a join in my select query depending upon a variable @LoggedUser. the Join is to be there if @loggedUser is 1 else i do not need it. Currently I am using two different queries one with join and one without it under If (@LoggedUser check).
the join is like -
JOIN (SELECT CAST(CONVERT(VARCHAR(8),Analyst_Effective_date , 1) AS DATETIME) Analyst_Effective_date
FROM Users us (NOLOCK) JOIN Primary_Analysts (NOLOCK)
ON User_Count_Id = Analyst_Id_fk
WHERE User_Count_Id in ((SELECT VALUE FROM dbo.fParseString(@Analyst, ',')) )) Ana
ON dep.Departure_Code = Ana.Primary_Analyst_Departure_Code_fk
)
Any way that the join can be added conditionally in the query so i do not have to write the whole code again for one join.
I have two tables tabA (cola1, cola2, cola3) and tabB(colb1, colb2, colb3, colb4) which I need to join on all 3 columns of table A.
Of the 3 columns in tabA, few can be NULL, in that case I want to check the joining condition for the rest of the columns, so its conditional joining. Let me rephrase what I am trying to acheive - I need to check if the columns in joining condition is NULL in my 1st table (tabA), If so I need to check the joining condition for the rest of the two columns, if 2nd column is again NULL, I need to check the joining condition on the third column.
What I am trying to do is as below. Its working, but is very slow when one of the tables is huge. Can I optimize it or rewrite in a better way ?
--- First Create two tables
Create table tabA
(cola1 nvarchar(100), cola2 nvarchar(100), cola3 nvarchar(100))
Insert into tabA values (NULL,'A1','A2')
Select * from tabA
create table tabB

I have a merge join that does a full outer join. I then have a conditional split that will breakout by unchanged, insert and update. The update is what I am having a problem with. The conditional split for the update is a follows:
!ISNULL(HISTORICAL) && !ISNULL(TRANSFORM)
Now I believe the problem is related to spaces in the key field let me explain.
The join field is defined as [char](14) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
There was an original mismatch between the two tables of VARCHAR(14) & Char(14) but now there both Char(14).
What's interesting is that the few records with Alpha characters correctly does the update but the records with starting numeric data all go down the insert path.
The data of the join columns look like
'308811151 ' - 5 Spaces This Data incorrectly goes to insert path
'TSTRWR02 ' 6 Space This Data correctly goes to update
The data is grouped and sorted by the Key field and the historical and transform column contain a 1 for all records.
while the Doc_nbr which is the key
I tested the join in SQL server and it works with and without the spaces.
From SSIS I also tried RTRIM in the SQL command of the source in addition to substring the first 9 with the right trim and I always received the same results.
I am guessing there is something going on with the not isnull in the conditional split but I can't figure it out if I am missing something or if this is a BUG.
Three paths of data after the merge join and the conditional split
Insert
DOC_NBR,HISTORICAL,TRANSFORM,DOC_NBR_historical
206352185 ,,1,
209900165 ,,1,
Update
DOC_NBR,HISTORICAL,TRANSFORM,DOC_NBR_historical
NEE ,1,1,NEE
New ,1,1,New
Unchanged
DOC_NBR,HISTORICAL,TRANSFORM,DOC_NBR_historical
,1,,0000521096
,1,,0000685216
Any suggestions, am I missing the obvious?

I am writing a stored procedure that takes in a customer number, a current (most recent) sales order quote, a prior (to most current) sales order quote, a current item 1, and a prior item 1, all of these parameters are required.Then I have current item 2, prior item 2, current item 3, prior item 3, which are optional.
I added an IF to check for the value of current item 2, prior item 2, current item 3, prior item 3, if there are values, then variable tables are created and filled with data, then are retrieved. As it is, my stored procedure returns 3 sets of data when current item 1, prior item 1, current item 2, prior item 2, current item 3, prior item 3 are passed to it, and only one if 2, and 3 are omitted.I would like to learn how can I return this as a one data set, either using a full outer join, or a union all?I am including a copy of my stored procedure as it is.
I have two tables:
1. tblProducts
columns: ProductID, ProductName
2. tblProductCodes
columns: ProductID, CustomerID, ProductCode
The 2nd table is for storing product codes for customers, in other words, one product can have different ProductCode for different customers. But some customers do not have ProductCode for a ProductID.
I want to create a query to return all the Products and its ProductCode (null is valid) for a specific customer.
I tried:
SELECT dbo.tblProductCodes.ProductCode, dbo.tblProductCodes.CustomerID,
dbo.tblProducts.ProductName,
dbo.tblProducts.ProductID
FROM dbo.tblProducts LEFT OUTER JOIN
dbo.tblProductCodes ON dbo.tblProducts.ProductID = dbo.tblProductCodes.ProductID
WHERE dbo.tblProductCodes.CustomerID = 2
But the query left out all products that does not have ProductCode value in tblProductCodes table for CustomerID = 2. I want all the ProductName returned from query and render null or empty string for ProductCode value if the code does not exist in tblProductCodes table for the customer.
Any help is highly appreciated.
Forgive the noob question, but i'm still learning SQL everyday and was wondering which of the following is faster? I'm just gonna post parts of the SELECT statement that i've made changes to:
INNER JOIN Facilities f ON e.Facility = f.FacilityID AND f.Name = @FacilityName
OR
WHERE f.Name = @FacilityName
My question is whether or not the query runs faster if i put the condition within the JOIN line as opposed to putting in the WHERE line? Both ways seems to return the same results but the time difference between methods is staggering? Putting the condition within the JOIN line makes the query run about 3 times faster?
Again, forgive my lack of understanding, but could someone agree or disagree and give me the cliff-notes version of why or why not?
Thanks!
Hello everyone,
Is there a way in order to execute a subscribed report based on a certain criteria?
For example, let's say send a report to users when data exist on the report else if no data is returned by the query
executed by the report then it will not send the report to users.
My current situation here is that users tend to say that this should not happen, since no pertinent information is contained in the report, why would they receive email with blank data in it.
Any help or suggestions will be much appreciated.
Thanks,

I tried to backup the master key by the following syntax :
OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'
BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'
but it failed and i got the following message:
Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.
NB: I am using the "sa" user to execute this command.
I know that we have a security permission issue , but where and how ?

I have the following code in the color property of a textbox. However, when I run my report all of the values in this column display in green regardless of their value.
=SWITCH(Fields!Wrap.Value >= 3, "Red", Fields!Wrap.Value < 3, "Green")
I already tried =iif(Fields!Wrap.Value >= 3 , "Red", "Green") and got the same results.
Is it because this is a matrix report? What am I doing wrong?

I have two xml source and i need only left restricted data.
how can i perform left restricted join?
I was writing a query using both left outer join and inner join. And the query was ....
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT
S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
LEFT OUTER JOIN Production.Categories AS C
ON C.categoryid = P.categoryid)
ON
S.supplierid = P.supplierid
WHERE
S.country = N'Japan';
The result i got was same,i.e
supplier country productid productname unitprice categorynameSupplier QOVFD Japan 9 Product AOZBW 97.00 Meat/PoultrySupplier QOVFD Japan 10 Product YHXGE 31.00 SeafoodSupplier QOVFD Japan 74 Product BKAZJ 10.00 ProduceSupplier QWUSF Japan 13 Product POXFU 6.00 SeafoodSupplier QWUSF Japan 14 Product PWCJB 23.25 ProduceSupplier QWUSF Japan 15 Product KSZOI 15.50 CondimentsSupplier XYZ Japan NULL NULL NULL NULLSupplier XYZ Japan NULL NULL NULL NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
I have two select statements, in between select statement taking UNION ALL . I need to avoid the error
Warning: The join order has been enforced because a local join hint is used.
Scenario:
OLEDB source 1
SELECT ...
,[MANUAL DCD ID] <-- this column set to sort order = 1

OLEDB source 2

...

These two tasks are followed immediately by a MERGE JOIN

Why is it failing for this one row?
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?
View 4 Replies View RelatedI have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?
View 3 Replies View RelatedI'm using SQL Server 2005.
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
Thanks,
