How To Insert A Row With Lowest Possible Key?
Aug 29, 2007
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!

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

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

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.

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

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
group by RRCID, MONTH
order by YEAR, MONTH
Results:

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

3Â Â Â 2Â Â Â Â Â Â 2
4Â Â Â 0Â 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
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

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

I have a web form with a text field that needs to take in as much as the user decides to type and insert it into an nvarchar(max) field in the database behind. I've tried using the new .write() method in my update statement, but it cuts off the text after a while. Is there a way to insert/update in SQL 2005 this without resorting to Bulk Insert? It bloats the transaction log and turning the logging off requires a call to sp_dboptions (or a straight-up ALTER DATABASE), which I'd like to avoid if I can.

An insert statement was not inserting all the data into a table. Found it very strange as the other fields in the row were inserted. I ran SQL profiler and found that sql statement had all the fields in the insert statement but some of the fields were not inserted. Below is the sql statement which is created dyanmically by a asp.net C# class. The columns which are not inserted are 'totaltax' and 'totalamount' ...while the 'shipto_name' etc...were inserted.there were not errors thrown. The sql from the code cannot be shown here as it is dynamically built referencing C# class files.It works fine on another test database which uses the same dlls.

and that causes (at line 67):"The INSERT statement conflicted with the FOREIGN KEY constraint

'id'.
The statement has been terminated.

Is there a way to avoid entering column names in the excel template for me to create an excel file froma dynamic excel using openrowset.
I have teh following code but it works fien when column names are given ahead of time.
If I remove the column names from the template and just to Select * from the table and Select * from sheet1 then it tells me that column names donot match.
Server: Msg 213, Level 16, State 5, Line 1Insert Error: Column name or number of supplied values does not match table definition.
here is my code...
SET @sql1='select * from table1'SET @sql2='select * from table2'
IF @File_Name = '' Select @fn = 'C:Test1.xls' ELSE Select @fn = 'C:' + @File_Name + '.xls' -- FileCopy command string formation SELECT @Cmd = 'Copy C:TestTemplate1.xls ' + @fn
-- FielCopy command execution through Shell Command EXEC MASTER..XP_CMDSHELL @cmd, NO_OUTPUT -- Mentioning the OLEDB Rpovider and excel destination filename set @provider = 'Microsoft.Jet.OLEDB.4.0' set @ExcelString = 'Excel 8.0;HDR=yes;Database=' + @fn
exec('insert into OPENrowset(''' + @provider + ''',''' + @ExcelString + ''',''SELECT * FROM [Sheet1$]'') '+ @sql1 + '') exec('insert into OPENrowset(''' + @provider + ''',''' + @ExcelString + ''',''SELECT * FROM [Sheet2$]'') '+ @sql2 + ' ')

Hello, I'm new to the forum and new to SQL, ASP.NET, etc. I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve. I have tried Googling it and came up empty. I have a database in SQL Express 2005 and my website will be accessing several tables within the database. I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set. The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine. The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks

On my site users can register using ASP Membership Create user Wizard control.
I am also using the wizard control to design a simple question and answer form that logged in users have access to.
it has 2 questions including a text box for Q1 and dropdown list for Q2.
I have a table in my database called "Players" which has 3 Columns
UserId Primary Key of type Unique Identifyer
PlayerName Type String
PlayerGenre Type Sting
On completing the wizard and clicking the finish button, I want the data to be inserted into the SQl express Players table.
I am having problems getting this to work and keep getting exceptions.
Be very helpful if somebody could check the code and advise where the problem is??

Event Handler
To match the answers to the user I get the UserId and insert this into the database to.protected void Wizard1_FinishButtonClick(object sender, WizardNavigationEventArgs e)
{
SqlDataSource DataSource = (SqlDataSource)Wizard1.FindControl("InsertArtist1");
MembershipUser myUser = Membership.GetUser(this.User.Identity.Name);
Guid UserId = (Guid)myUser.ProviderUserKey;String Gender = ((DropDownList)Wizard1.FindControl("PlayerGenre")).SelectedValue;
DataSource.InsertParameters.Add("UserId", UserId.ToString());DataSource.InsertParameters.Add("PlayerGenre", Gender.ToString());
DataSource.Insert();
}
