Let's say I have a result set (records) containing numbers such as:
0
1
2
3
9
16
21
45
100
101
102
103
104
105
106
How might someone write a procedure to get the next lowest number in
this sequence? In this case it would be: 4. Some combination of
Select, Min & When, I am sure, but it escapes me at the moment.
Thoughts? Thanks...
Hye all.. ;-)Question : 1. I try to Retrieve "00012" number from SQL Database..But the Return value is "12"..Wht I need is "00012" not "12". How I gonna do that?2. Because why..I need to save again that number in another Table. I'm using Data Type as "nvarchar(50)". Thank you.

HI,
I have one master table and multiple detail tables. The primary key of the master table is an auto-increment number, which is a foreign key in those detail tables. I am wondering if SQL Server allows us to get the next available auto-increment number of the master table up front. Thanks a lot.
Is there any way to retrieve partial contents of a database column? For example, say a column holds 5,000 characters, but I only wish to retrieve the first 50.
Thanks
I€™m working on a database project that will ultimately contain millions of records for each lot. In addition, each lot will have up to 96 corresponding serial number records.
I would like to add a SQL parameter that would tell the database engine to only return X number of records.
For Example:
If table TBL_LOTS contains one million records I would like to limit the return set to 100 for example.
What would I need to add to the SQL command to below to restrict the data set to the first 100 records in the set of one million?
SELECT [LOT NUMBER]
FROM TBL_LOTS
WHERE [STATMENTS]
hi friends,
i got a error while retrieving more than 100000 rows (records) from a table .. can any one tell me what is the maximum number of rows retrieve from a database to reports... and how can i overcome this issue...
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
SELECT
S.Id
, RMA
, PinSerial
, L4Serial
, L4Model
[Code] ....
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,
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
Is there a more elegant way to do the following?...declare @d1 datetime, @d2 datetimeset @d1 = '2005-01-01'set @d2 = '2005-02-01'selectcasewhen datediff(dd,@d2,@d1)is nullthen coalesce(@d1, @d2)when (datediff(dd,@d2,@d1)> 0)then @d2else @d1endCheers,..N
View 2 Replies View RelatedHi, 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!

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.

View 1 Replies View RelatedI'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.
Hello,
I have a long stored procedure that performs some inserts and updates on the table that users are accessing through a user interface. We this stored procedure runs users experience slowness, is there any way I can get the stored procedure runs with a lowest priority so that user will be able to perform their tasks first.
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
finding the first value to cross a specific threshold in SQL Server
LoadTemp1 LoadTemp2 LoadTemp3 TimeStamp
300 350 200 12-10-2013 13:30
177 238 333 12-10-2013 13:05
240 190 170 12-10-2013 12:45
How do I design query to find the first LoadTemp* that cross a threshold of 340 degrees per TimeStamp.
I need to display the difference between the highest and lowest salaries. Label the column DIFFERENCE. like below:
From what I came up with is should look something like so:
<b>SQL> select * from 'salary' order by salary desc limit
select * from 'salary' order by salary desc limit 1,1 </b>

I am attempting to only query the lowest year, and month from my entire production database.

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!!
I have hierarchical data such as:
Id   Level   ParentId
1Â Â Â 0Â Â Â Â Â Â 1
2Â Â Â 1Â Â Â Â Â Â 1
3Â Â Â 2Â Â Â Â Â Â 2
4Â Â Â 0Â Â Â Â Â Â 4
5Â Â Â 1Â Â Â Â Â Â 4
6Â Â Â 0Â Â Â Â Â Â 6
7Â Â Â 1Â Â Â Â Â Â 6
8Â Â Â 2Â Â Â Â Â Â 7
9Â Â Â 3Â Â Â Â Â Â 8Â Â Â Â Â Â
10Â Â 4Â Â Â Â Â Â 9
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
10Â Â 4Â Â Â Â Â Â 9
11Â Â 0Â Â Â Â Â Â Â Â 11
If I install SQL Server using a certain Windows Login, does that login assume some sort of "sa" alias?
(I'm trying to explain the behaviour that when I login in to a server using the same username that I used when i installed the SQL Server instance, using trusted authentication, then use a database within which I haven't created any users, I seem to get full permissions, as if I had gone in as "sa")
In the scenario where you are installing MSDE/SQL Server at a customer site (not your own) is this true:
Assuming the customer has a (Windows) login with admin rights (or is a member of the admins group) over the PC which the server was installed on, there is no way of locking the customer out of any part of the SQL Server installation and its databases as Mixed Authentication (which you can't turn off) will always allow members of the (Windows) admins group to also be a member of the SQL Server admins group???
