I have a table which maps two related IDs. That table has 3 columns: ID, BHID & EPID. I need to find all of the BHIDs where the EPID is unique. It seems easy enough, but I keep going in circles..
USE [CGB]
GO
/****** Object: Table [dbo].[ePID_BHID] Script Date: 04/15/2015 15:48:14 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[code]....
how to find all possible combinations of values, for example:
My table includes:
Code:
CREATE TABLE temp1 (item varchar(50), ORDER int);
INSERT INTO temp1 (item, order) VALUES ('apple',1);
INSERT INTO temp1 (item, order) VALUES ('pear',2);
INSERT INTO temp1 (item, order) VALUES ('blueberry',3);
I need the output to be like this:
apple
pear
blueberry
apple, pear
apple, blueberry
pear, blueberry
apple, pear, blueberry
I don't need the reverse of each. For example, I need only 'apple, pear'... I don't need 'pear, apple'.
I am using Access 2007 and I have 10 columns of data.
I am trying to select all the data from all 10 columns where the first column's data returns only the Unique values and the other columns return all the data from the row that is returned from the first column.
I have used this
SELECT DISTINCT [SFR Rates All].Sorter, [SFR Rates All].SProgram, [SFR Rates All].S_Price, [SFR Rates All].Min_Loan, [SFR Rates All].Max_Loan
FROM [SFR Rates All];
But that returns all the data in the table and all values in the Sorter column with duplicates because each row has distinct data.
I am trying to return unique values from [SFR Rates All].Sorter (the first column) and all the data from the other 9 columns that are contain the row with the unique value in Sorter.
I know that I am missing something basic but well, I can't figure it out.
Thanks

I am in a situation where I need to find out unique field names with different values in a table having 200+ columns.
Let's say I have two rows with 200+ columns ( I exported these rows from Lotus Notes to SQL Server) I am not sure what columns makes unique of these rows. It's going to be tedious by checking each column values.
Is there anyway I can write a squl query on these two rows which outputs column names which are having unique values.
I would appreciate If anybody gives me hint about achieving desired result
Hi, all,
I have a question about adding a unique key column to an existing table.
what i trying to do is that: I have already created a table, now i wanna add a ID column to this table, and generate the values for ID column from 1 to the existing row number. How can I get this done?
Thanks a lot in advance for any guidance.
A common partitioning scenario is when the partition column has the same value for every record in the partition, as opposed to a range of values. Am I the only person who wonders why there isn't an option to automatically partition a table based on the unique values of the partition column? Instead of defining a partition function with constants, you ought to be able to just give it the column and be done. This would be particularly valuable for tables partitioned on a weekly or monthly date; when new data is added it could simply create a new partition if one doesn't already exist.

I have to delete a single row from a table , where there are multiple rows with the same data and i want to delete only one row and i cannot alter my table
structure.

HI all,
I am having a bit of difficulty trying to work how to write a query. I am normally only used to doing SELECT, UPDATE and DELETE queries ... the simple ones.
However I have come across a query whereby things get a lot more complex.
My company has an employee table with a way to store data that I have not been used to.
EMPLID, NAME, DATELASTMODIFIED, EmployeeStatus. (There are lots more but N/A)
The problem that I have is that there can be more than one row for an employee id. Therefore I cannot uniquely identify an employee id. Instead what I have discovered I have to use is to find an employee with the last modified date higher than the other rows with the same employee id.
The query I am trying to achieve is:
Code:
Count all employees that have an employee status of 'Employed'.
(Therefore counting only one employee per id rather than counting the same employee more than once)
The trouble is, translating this into a SQL query. I have tried to have a go but don't know how to query:
Code:
SELECT COUNT (DISTINCT EmplId)[
FROM Employeetable AS e
WHERE e.LASTDATEMODIFIED <And Stuck>
AND EmployeeStatus = 'Employed'
So I thought hmm lets pseudo code this, but then I get stuck into compelixty:
Code:
SELECT * FROM EmployeeTable WHERE EmployeeStatus = 'Employed'
int counter = 0;
ForLoop (EmplId)
{
LastDate Date
if(LASTMODIFIEDDATE > LastDate)
{
LastDate = LASTMODIFIEDDATE
}
//How do I return the value? Do I count the value?
}
Has anyone come across this issue before? Can anyone help it quite fundemental to what I have to query so help on this is highly appreciative.
I have a scenario here where the data looks like -
IDÂ Â Â Â Â Â Â Date
100Â Â Â Â Â Â 07/01
100Â Â Â Â 07/02
100Â Â Â 07/03
100Â Â 08/01
100Â Â 08/02
100Â Â 08/15
Now I need to find out unique occurrences of ID - 100 ( where count =Â unique only if the occurrences are in consecutive days, gap of even 1 day causes it to be a different instance ) - SO with the above data I should have unique occurrences as 3.efficient way to calculate this ?
Hi
I am new to SQL. My scenario is I get a string from the user I need to match this string with value present in 2 cloumns. If the string is present in either of the column then i should select that particular record from the table.
Now my question is if i Have to match with one cloumn i can used charindex function is there any function with which i can match the string with data present in more than one cloumn.
Thanks Much

Hello,
I have a web form with a check box list with 5 values. Each of them is an int value, and the user can select multiple values from the check box list. For example:
Status:
1) Single
2) Married
3) In Relationship
4) Divorced
5) Any
These values correspond to a column called "RelationshipStatus" which holds an int value of NULL or 0-5.
So the value passed to my SQL query would be any combination of 1, 2, 3, 4, or 5 (Which denote any of the above). It could look like this:
@Status = '132'
Now my question is how would I do a select statement that finds any row with one of those value (Any row with 1, or 3, or 2)? If there is a '5' in the varible then the select statement should return any row regardless of the value.
Table Name: "USER_TABLE"
Column Name: "Relationship_Status"
Value Type: INT
Thank you experts!
I have a query I am currently attempting to optimise. Â The query joins in on a sub table (queries the same table) to garner a maximum date value for each row to display. Â For example:
SELECT Column1
,Column2
,DateColumn
FROM Table1 T
INNER JOIN
(
SELECT Column1 + Column2 AS ConcatColumn, Column3, MAX(DateColumn) AS dt
FROM Table1
GROUP BY Column1 + Column2
) X ON X.ConcatColumn = T.Column1 + Column2 AND X.dt = T.DateColumn
Is there any way I can write this another way (preferably more cleaner/optimised)?
Hi Everyone,
This is the table I have:
Sections Class1 Class2 Class3 Class4
--------------------------------------------------------------------
A 30 20 30 40
B 40 15 10 10
C 20 5 10 5
Total 90 40 50 55
There are around 6 more classes which I haven't mentioned. The resultant table that I need would be something like this.
Sections Class1 Class4 Others
-------------------------------------------------
A 30 40 50
B 40 10 25
C 20 5 15
Total 90 55 90
What I want is the top two maximum values to appear and everything else to be clubbed into Others and correspondingly their numbers to be summed up i.e. Dynamically depending on the total only those classes with maximum 'Total' value to appear.
Hi,

1 Sample Item Sample Brand - 1 Sample Brand - 2
How to get the desired output?
First of all, we are using SQL Server 2005 with a SQL Mobile subscriber and we are attempting to use Data Partitions on our current database
schema which contains associative tables for many-to-many relationships.
We have two tables, a User table
and an Audit table. A user can be
assigned more than one Audit. An Audit
can be assigned to more than one User.
So an AuditUser associative table exists. If data partitions are used based on User,
then any Audits that are assigned to one or more users should be copied to the
proper partition for each User (the msmerge_current_partition_mappings table
with the proper partition_id values).
In order to insert records with such a schema, the following
steps occur in order:
Insert
new row into Audit table with new rowguidInsert
entry into AuditUser table associating the auditguid with every userguid that
is assigned this audit.
Merge replication triggers are fired on insert of the Audit
row and another one for the insert of the AuditUser row.
When the Audit row is inserted, the replication trigger follows
the following logic:
Inserts
a copy of that row into the msmerge_contents table. Evaluates
the row to determine which partition(s) this row should be copied to as
well (msmerge_current_partition_mappings table). To do this, it checks to see if the
AuditGuid is referenced in one or more AuditUser rows. Since we haven€™t inserted the AuditUser
row at this point, the trigger€™s logic doesn€™t find a partition to copy
this row to.
When the AuditUser row is inserted, the replication trigger performs
the same logic as with the Audit row, it:
Inserts
a copy of that row into the msmerge_contents table.Evaluates
the row to determine which partition(s) this row should be copied to as
well (msmerge_current_partition_mappings table). Since the row meets the criteria for one
or more partitions, it is copied to the msmerge_current_partition_mappings
table for each partition that exists.
When replication occurs, we see only the AuditUser rows
copied down to our device, and not the corresponding Audit rows. Now that we understand the triggers, it is
plain to see why. If the AuditUser row
could be inserted first, then the trigger on the Audit row would copy that row
into the proper partitions and all would work well. However, the Audit row must be inserted
first, so that foreign key relationship constraints are preserved.
It seems that the Update trigger on the AuditUser row
actually walks the relationships and copies any related child rows to the
msmerge_current_partition_mappings table.
Hello,
I don't know if this is the correct forum or if it would perhaps be the server setup & upgrade, however, I'll ask here first. I am going through the SQL 2005 data mining tutorials and have encountered an error that states:
Query (1,6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[AssociationRules].[GetStatistics]' function does not exist.
After looking around for a bit it appeared that this function is generally used in a stored procedure run from the server. Is this correct? What do I need to do to either correctly import the function into the project or to make sure that it is installed on the server?
We are running the Ent Ed. now, however, we just upgraded to this after I had already started on this project. Could that be a problem?
Any help on this would be greatly appreciated.
Thanks for your time.

Hi all...I've got a group of tables and I wanted to first see which tablescontained a fields containing the "Date/Time" data type. And I wassuccessful in doing so...here's the query:(select a.name tablename, b.name colnamefrom sysobjects a, syscolumns bwhere a.name = object_name(b.id)AND B.TYPE = 61 AND A.XTYPE = 'U')Now...my only issue is find which query I can run (On each table)which returns to me ONLY the values containing the date/time stampwith milli seconds (Ex: 01/01/2007 10:10:50:987)I require this since we are planning on shifting those tables to theOracle platform, and we've had issues doing this while loading theextracted information, since it was not taking the values containingthe "milliseconds".Is there a way to do this? Or is it better to simply remove themilliseconds all togeather? I wouldn't mind doing so provided that itdoesn't includes changes to the actual data type.
View 1 Replies View RelatedHere's what I'd like to be able to do: I have a queue that holds any number tasks, so something like this here:
queue_1 task_a
task_b
task_c
task_d
Workers are assigned to teams, Red team, Blue team, Green team. What I need to do is identify instances where all tasks for a given queue have been handled by one team. Once a task has been assigned to a queue any team can work on it, but when only one team has completed every task in a queue a bonus should be awarded.
I'm looking for this to award a bonus:
queue_num task_num team
queue_1 task_a red
task_b red
task_c red
task_d red
No bonus for any team here
queue_num task_num team
queue_1 task_a red
task_b blue
task_c red
task_d green
So the red team earns a bonus. Now, I have thousands of queues each containing any number of tasks. Using T-SQL how can I find all queues where only one team was responsible for completeing every task assigned to the queue? Do I have to use a cursor and eval each task coming through or is there a faster, more efficient way to handle this in SQL?
The following is sample data I am dealing with.
SELECT * INTO TEMP

SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '02-01-2014' AS STARTDATE, '02-28-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '03-01-2014' AS STARTDATE, '03-31-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A2000' AS CODE, '04-01-2014' AS STARTDATE, '04-30-2014' AS ENDDATE
UNION
SELECT 'AAAAA' AS CATEGORY, 'A1000' AS CODE, '05-01-2014' AS STARTDATE, '05-31-2014' AS ENDDATE) X
I need to extract the date that the value in CODE column changes to another code for each value of CATEGORY and if there is no change, to record the original CODE value and its startdate for each CATEGORY.
I'm trying to come up with a query for this data:
CREATE TABLE #Visits (OpportunityID int, ActivityID int, FirstVisit date, ScheduledEnd datetime, isFirstVisit bit, isRepeatVisit bit)
INSERT #Visits (OpportunityID, ActivityID, FirstVisit, ScheduledEnd)
SELECT 1, 1001, '2014-08-17', '2014-08-17 12:00:00.000' UNION ALL
SELECT 1, 1002, '2014-08-17', '2014-08-17 17:04:13.000' UNION ALL
SELECT 2, 1003, '2014-08-18', '2014-08-18 20:39:56.000' UNION ALL
[Code] ....
Here are the expected results:
OpportunityIDActivityIDFirstVisitScheduledEndisFirstVisitisRepeatVisit
110012014-08-172014-08-17 12:00:00.00010
110022014-08-172014-08-17 17:04:13.00001

210042014-08-182014-08-18 18:00:00.00010
[Code] ....
Basically I'd like to mark the first Activity for each OpportunityID as a First Visit if its ScheduledEnd falls on the same day as the FirstVisit, and otherwise mark it as a Repeat Visit.
I have this so far, but it doesn't pick up on that the ScheduledEnd needs to be on the same day as the FirstVisit date to count as a first visit:
SELECT*,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 1
ELSE 0
END AS isFirstVisit,
CASE MIN(ScheduledEnd) OVER (PARTITION BY FirstVisit)
WHEN ScheduledEnd THEN 0
ELSE 1
END AS isRepeatVisit

I cannot make that table/unique column as indentity. Right now, I use a staging table with indentity column, insert rows then insert rows back to

View 2 Replies View RelatedHi, I have been asked to write some code that can check a large table for duplicate values in a non pk column. The table may have up to 1000000 rows. The PK column is an auto increment field. For performance reasons the column in question could not be set to unique values only for inserts, an algorithm is used to create unique no's before the insert but what I am doing is double checking that their have been no duplicates created accidently. If their are duplicates I need to know what rows they occurred on.

Hi,
Suppose a table [Inventory]:
Item Color Quantity
-------------------- -------------------- --------------------------
Table Blue 10
Table Red 20
Table Yellow 30
Chair Blue 40
Chair Red 50
I'm wondering if there is a group state like this:
Select Item, ?Function(Color), Sum(Quantity) From Inventory Group by Item
which returns this:
Table Blue,Red,Yellow 60
Chair Blue,Red 90
Does anyone has an idea how this can be achieved?

I am working on an ASP.net web application which inserts new record into an underlying table.
It is actually a ConfirmationNumber and should be unique. I have used abs(checksum(newid()))
For this purpose. Is there a better way to accomplice this?
I need a query to return two values. One will be the total units and the other will be total unique units. See exmaple data below. It does not have to be one query. This will be in SP, so I can keep it seperate if I have to.
ID | ID_UNIT
1 | 01
1 | 01
1 | 02
1 | 03
1 | 03
1 | 04
1 | 04
I need two results.
Total Units = 7 - easy to do by using count()
Total unique units = 4 - I cannot use group by as it would return multiple results for each unit, which is not what we want.
I am getting same value all over how to get unique values for each measures.
how to resolve it.
Hi All,
I need a bit of help with a join. I have 2 tables :
TradeSummary
has fields : SymbolID, CurrentPrice, TotalValue
Trades
has fields : SymbolID, TradeID, ExecutionTime, TradeValue
TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID
and what I want to retreive is :
For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary
and also get TradeValue from Trades for the record for max(ExecutionTime)
tables are joined on TradeSummary.SymbolID = Trades.SymbolID
Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID
thanks in advance
I have 2 identical tables one contains current settings, the other contains all historical settings.I could create a union view to display the current values from table A and all historical values from table B, butthat would also require a Variable to hold the tblid for both select statements.

DECLARE @tblid int = 501
SELECT 1,2,3,4,'CurrentSetting'
FROM TableA ta
WHERE tblid = @tblid
UNION
SELECT 1,2,3,4,'PreviosSetting'
FROM Tableb tb

Its showing a syntax error near @N. How can i pass the parameter for Select Top @N * from .......
I have this query and it works except for I am getting duplicate primary keys with unique column value. I want to combine them so that I have one primary key, but keep all the columns. Example:
Key column 1 column 2 column 3 column 4

A 2 2
B 2 3
B 5 5
it should look like:
A 1 1 2 2
