The Lowest Value Between Two Columns?
Sep 14, 2012
SELECT
@AppId AS Application_Id
, MB.POLICY_ID AS Policy_Id
, MH.BFN_CHG_DATEAS Date_Of_Disinvestment
, AD.X_INVEST_AMT AS Original_Investment_Value
, MB.TOTAL_AMOUNT AS Encashment_Value
, WH.TOT_COMMISSION AS Top-Up_Commission
FROM: I select from lot of table, as specified from my select statement
My output:
AppId PolicyId Date_Of_DisIn Original_Inv Encashment_Value Top-Up_Commision ???
1-1-1; 1000000; Jan-01-12; 2882.07; 3312.00; 2306; ??
My Aliases returns just one values, of which that's what I am expecting, so I need to make a comparison between Original_Investment_Value and (Encashment_Value + Top-Up_Commision), and return the lowest value

Im having trouble finding a solution to comparing columns to find the lowest value.
Example
Row 1
COL 1 = 10
COL 2 = 20
COL 3 = 60
COL 4 = 5
COL 5 = 35
I would want to return 5.
I tried to write a case statement such as below but am unable to use Logical Operators.
WHEN C1 <= C2 and C1<= C3 THEN C1
WHEN C2 <= C3 THEN C2
ELSE C3
any help would be great.
Thanks,
Nick

OK, this should be an easy one but my brain isn't quite working right now.
I have a table, we'll call Table1 like so:
ProductID Supplier Cost
12345 A 14.50
12345 B 13.49
12345 C 12.00
43222 A 15.00
43222 B 15.21
43222 C 13.99
12312 B 14.00
15421 A 21.99
15421 C 20.00
And I want to Get the name of the Supplier with the Lowest cost,
I know I can go like:
SELECT ProductID, MIN(Cost) FROM Table1 GROUP BY ProductID
and get the lowest cost, but what would be the most effiecent way to get all three fields returned by the query? I need the ProductID, Supplier and Cost.
Thanks,

Hi, this seems to be an easy question but I can't find a quick answer to it.
I have an asp page that communicates with a database and I want the following example to work...
Insert 5 records into the DB with primary keys 1-5.
Remove record with key number 2.
Now, if I insert a new record I want it to take the smallest available key number (in this case number 2). This will save space in the database and keep the key numbers from increasing forever.
Does auto increment work like this?
If not, how do I do it?
Thanks for any replies!

I'm using sql express 2005. I need help with buliding a view.
I'm trying to join two tables and then, if duplicate ID's exist, retrieve the row with the lowest value in a specific column.
For instance:
TableHousehold:
ID Name Status
001 The Smith€™s A
002 The Jone€™s A
003 The Adam€™s A
004 The Grant€™s A
TableResidents
Pk HouseholdID ResidentID Name Gender
1 001 1 Mary Smith F
2 001 2 Jason Smith M
3 001 3 Rachel Smith F
4 002 1 Mike Jones M
5 002 2 Sara Jones F
6 003 2 Erik Adams M
The resident ID is auto increment and assigned by the server. It is possible for resident 1 for each household to have been deleted. It is also possible that a household does not contain any residents. Therefore, I wish to join these tables and return this:
ID HouseHoldName Status ResidentName Gender
001 The Smith€™s A Mary Smith F
002 The Jone€™s A Mike Jones M
003 The Adam€™s A Erik Adams M
004 The Grant€™s A null null
There are other columns in both tables that I will want to join, but for simplicity, the above example illustrates my need.
I was able to accomplish this by creating two views. But I€™d like to try and do this in one.

I have a little problem that I just haven't been able to solve. I don't think it is very difficult but I can't seem to make it work. Here's the scenario:
I have a database with the following values:
Model Make Price
DA1100 GTN$88.00
DA1100 GTN $100.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00
In this case DA1100 is listed twice with 2 different prices. I only want to display the one with the lowest price. So the result I want is:
Model Make Price
DA1100 GTN$88.00
DA1000 GBN$110.00
DA668 GTN$100.00
DA880 GTN$200.00

Let's say I have a result set (records) containing numbers such as:01239162145100101102103104105106How might someone write a procedure to get the next lowest number inthis sequence? In this case it would be: 4. Some combination ofSelect, Min & When, I am sure, but it escapes me at the moment.Thoughts? Thanks...

I am attempting to only query the lowest year, and month from my entire production database. I am using the following query and when I do it individually it will bring back the lowest year but also with additional years. How can I remove those other years so I can only query the lowest year and month from the entire database?
Code:
select distinct RRCID, MIN(YEAR)as YEAR, MONTH
from Gas_Prodv1
where RRCID = 1221376

ID (PK), userID (FK), from [Datetime], to[datetime], type [int] , value [nvarchar]
Conditions
I want to select the column "to" which is a datetime-column for all users within the table.
One user can have multiple registered rows in "mytable", so I want to select the row that contains the newest "from" date.The newest "from"-column for a specific user is where I am struggling... Because if the "to"-column of any of the registered rows by the current user is equal to the newest "from -1 day" column for the user, I want to select the second newest from-date.
Code:
//Handwritten
DECLARE @from DATETIME //Current Selected datetime [the newest of the current user doing the query]
DECLARE @id INT //userID
DECLARE @tbl TABLE (from datetime, userid int)
[code]....
But for user ID 201 [all users with Type = 1], I need to run through some more code, to figure out which date we want... Which date do I want? The "from"-date that is the newest, but if "to" is just 1 day before "from", I want to select the "from" at that row instead... Example with numbers [integers] instead of Date:
Code:
From - To
5 8
10 15
16 20
I want to select "10" in the from column as the maximum "from"-integer, and not 16. Because in the "To" column we have a match in the "from" column on the condition "To + 1" [15+ 1 == 16], so then I want the "from" value where "To" equals 15, which is 10. The top row I do not want, because the difference between From and To [10 - 8 is larger than 1]...
This means that the Image shown... I am first selecting the "1", then I do some checks, if the "to" for the user is 1 day earlier than the MAX(from) I grab a new "from" value...
Code:
SELECT MIN (t1.from) FROM table as t1
WHERE
t1.from IN
(
SELECT t2.to+ 1 FROM table as t2
WHERE t2.userID = @id
)

I have just been running a query which I was planning on improving by removing a redundant GROUP BY (there are about 20 columns, and one of the columns returned is atomic, so will mean that the "group by" will never manage to group any of the data) but when I modified the query to remove the grouping, this actually seems to slow the query, and I can't see why this would be the case.
Both queries return the same number of rows (69000), as I expected, and looking at the query plan, then they look nearly identical, other than at the start, there is a "stream aggregate" and "sort" being performed. The estimated data size is 64MB for the non-grouped query (runs in 6 min 41 secs), vs 53MB for the aggregated query (runs in 5 min 31 secs), and the estimated row size is smaller when aggregated.
Can rationalise this? In my mind, the data that is being pulled is identical, plus there is extra computation for doing an unnecessary aggregation, so the aggregated query should be unquestionably slower, but the database engine has other ideas; it seems to be able to work more quickly when it needs to do unnecessary work :) Perhaps something to do with an inefficient query plan for the non-aggregated query? I would have thought looking at the actual execution plan might have made this apparent, but both plans look very similar.
Edit: More information, the "group by" query had two aggregations on it, a count of one of the columns, and an average of another one. I changed this so that it was just "1" instead of the count, and for the average, I changed it to be the expression within the average aggregate, since the aggregation effectively does not do anything.

Hello Group,
I'm still a bit new to T-SQL and am wondering how to get various LOWEST values from a table, rather than TOP values. There does not appear to be a keyword opposite of TOP in T-SQL.
My real problem is this: I know how to get the 2nd highest value, third highest value, etc...but how does one get the 2nd lowest value, third lowest value, etc?
Would anyone be able to help?
Thanks!!

11Â Â 0Â Â Â Â Â Â Â Â 11
As you can see even the parent element has parentId(in this case id = parentid)
How can I select the lowest level data in the hierarchy and get this result:
Id   Level   ParentId
3 Â Â 2 Â Â Â Â Â 2
5Â Â Â 1Â Â Â Â Â Â 4

I've got a fairly large hierarchy table and I'm trying to put together a query to find the lowest level descendants of the hierarchy. I think there must be some way to use the "Breadth-first" approach that's stated in the MSDN technet sites about SQL Server HierarchyID but i'm not sure how to write the necessary T-SQL to traverse that. I know I can get all the descendants of a parent node like this
SELECT *
FROM AdventureWorks2012.HumanResources.Employee
WHERE OrganizationNode.IsDescendantOf(@ParentNode) = 1
However, this query returns all levels for that parent's branch. If I just wanted list of employees that were at the lowest level of the branch(es) for this parent node, how would I do this?

Hi,This is probably a classic scenario with a shared dimension that weneed to use in different cubes, where all fact tables do not offer thesame level of detail. Dimension is snow-flaked.The cube that's causing me troubles was designed by marking the lowestdimension level Diabled and not Visible. This allows me to get rid ofone of the snow-flake tables (the one with the lowest level), thusallowing an INNER JOIN with the remaining table which has a level ofdetail corresponding to the fact table.When processing the cube, I get a 'member with key '[blah]' was foundin the fact table but was not found in the level '[blah]' of thedimension '[blah]'' that seems to indicate that none of my fact foreignkeys exist as primary keys in the dimension table. However if I thenattempt to query the cube, all data seems to be there.Would anybody be in a position (and willing ;-)) to share his/her ownexperience working around a similar issue?Thanks,SRL

Hello:
I am running into an issue with RS2k PDF export.
Case: Exporting Report to PDF/Printing/TIFF
Report: Contains 1 table with 19 Columns. 1 column is static, the other 18 are visible at the users descretion. Report when printed/exported to pdf spans 2 pages naturally, 16 on the first page, 3 on the second, and the column widths have been adjusted to provide a perfect page span .
User A elects to hide two of the columns, and show the rest. The report complies and the viewable version is perfect, the excel export is perfect.. the PDF export on the first page causes every fith column, starting with the last column that was hidden to be expanded to take up additional width. On the spanned page, it renders the first column on that page correctly, then there is a white space gap equal to the width of the hidden columns and then the rest of the cells show with the last column expanded to take up the same width that the original 2 columns were going to take up, plus its width.
We have tried several different settings to see if it helps this issue or makes it worse. So far cangrow/canshrink/keep together have made no impact. It is not possible to increase the page size due to limited page size selection availablility for the client. There are far too many combinations of what the user can elect to show or hide to put together different tables to show and hide on the same report to remove this effect.
Any help or suggestion on this issue would be appreciated

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below)Â and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, Â fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.

Hi, all experts here,
Thanks a lot for your kind attention.
As I am creating the non-clustered indexes for the tables, I dont quite understand how dose it really matter to put the columns in the index key columns or put them into the included columns of the index?
I am really confused about that and I am looking forward to hearing from you and thank you very much again for your advices and help.
With best regards,
Yours sincerely,

Here's another one of my bitchfest about stuff which annoy the *** out of me in SSIS (and no such problems in DTS):
Do you ever wonder how easy it was to set up text file to db transform in DTS - I had no problems at all. In SSIS - 1 spent half a day trying to figure out how to get proper column data types for text file - OF Course MS was brilliant enough to add "Suggest Types" feature to text file connection manager - BUT guess what - it sample ONLY 1000 rows - so I tried to change that number to 50000 and clicked ok - BUT ms changed it to 1000 without me noticing it - SO NO WONDER later on some of datatypes did not match. And boy what a fun it is to change the source columns after you have created a few transforms.
This s**hit just breaks... So a word about Derived Columns - pretty useful feature heh? ITs not f***ing useful if it DELETES SOME of the Code itself after there have been changes in dataflow. I cant say how pissed off im about that SSIS went ahead and deleted columns from flow & messed up derived columns just because the lineageIDs dont match.
Meta-data - it would be useful if you could change it and refresh it - im just sick and tired of it that it shows warnings and errors when there's nothing wrong - so after a change i need to doubleclick all my transforms so that those red & yellow boxes would disappear.
Oh and y I passionately dislike Derived columns - so you create new fields based on some data - you do some stuff - combine multiple columns to one, but you have no way saying remove the columns from the pipeline. Y you need it - well if you have 50K + rows with 30+ columns then its EXTRA useless memory overhead for your package.
Hopefully one day I will understand how SSIS works (not an ez task I say) - I might be able to spend more time on development and less time on my bitchfest - UNTIL then --> Another Day - Another Hassle with SSIS
