Finding Unique Field Names With Different Values
Jun 8, 2005
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,
is there any "robust" way to find out the name of a field in the pipeline by it's Lineage ID programatically? There is a sample code out there (on one of the blogs) but it seams not to be reliable...
The usecase is easy... What is the field name in an error output of that column that causes the error? We don't want to have hardcoded LineageIDs in the error handling so I think it's the best idea to go with field names... However we only get that LineageID...
Thanks,

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 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

Any help here would be greatly appreciated...
Unfortunately, data wasn't filtered prior to getting inserted into this table. Now I am stuck with cleaning it up. I have thought about writing a query to update all the values, but there are just too many variations, including spelling mistakes, so I've ruled that out as a possible solution.
I have a table which has a Country field but the values per record vary. For example US, U.S., USA, United States, UK, United Kingdom, Canada, Can, etc. I'm trying to find the percent of records per country.
Sample table data: mytable
Id Name Country
1 John US
2 James UK
3 Jane United States
4 Mary Canada
5 Jack U.S.
6 Tony United Kingdom
7 Jeff US
8 Tom Canada
9 Beth UK
10 Mark USA
I would like to show
US: 50% --> (includes any variation of US ncluding US, U.S., USA, United States)
UK: 30%
CAN: 20%
I've made several attempts myself with no luck. Thanks in advance.

I have a comma separated field containing numerous 2 digit numbers that I would like splitting out by a corresponding unique code held in another field on the same row.
E.g
Unique Code Comma Separated Field
14587934 1,5,17,18,19,40,51,62,70
6998468 10,45,62,18,19
79585264 1,5,18
These needs to be in column format or held in an array to be used as conditional criteria.
Unique Code Comma Separated Value
79585264 1
79585264 5
79585264 18

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'm trying to do an update query that looks like this:
UPDATE
PAEMPLOYEE
SET PAEMPLOYEE.LOCAT_CODE = EMPLOYEE.PROCESS_LEVEL
FROM
PAEMPLOYEE A
JOIN EMPLOYEE B ON A.EMPLOYEE = B.EMPLOYEE
It's erroring out on the Employee prefix B.EMPLOYEE saying:
..."does not match with a table name or alias name used in the query"
Is it wrong or will it cause problems to have a field name the same as the table name?

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 all,My program is a central data processing application built in ASP.We have different companies that use different web pages on another webapplication (from different countries) to load some inventory data(merchandise - clothes).Here is my requirement: Load different types of data (in differentformats) into a common set of tables, to do this I have to firstfilter, do lookup's, use cross-reference tables on this data and thenload it into a couple of tables.Since data is so different everytime, I want to have one main storedprocedure in which I can build the table (I know the format of thisdata so I know what columns/types to create) into which I will feed thedata.After this I will create other stored procs/udf's that reference thistable (probably from the same main stored proc) 'cleanse' the databefore loading into the actual tables.How feasible is my approach? (if you can call it one :-) I do not wantto have seperate tables for each country, that will be too many and sothis plan...If not any other ideas will be really helpful.thanks much

Here's a portion of the current statement.
UPDATE EngagementAuditAreas
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = 0,
bControlRiskIsAffirmed = 0,
bCombinedRiskIsAffirmed = 0,
bApproachTypeIsAffirmed = 0,
bCommentsIsAffirmed = 0
FROM EngagementAuditAreas WITH(NOLOCK) ...
And what I need is to conditionalize the values of the "IsAffirmed" fields by looking at their corresponding "num" fields. Something like this (which doesn't work).
UPDATE EngagementAuditAreas
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = (numInherentRiskID IS NULL),
bControlRiskIsAffirmed = (numControlRiskID IS NULL),
bCombinedRiskIsAffirmed = (numCombinedRiskID IS NULL),
bApproachTypeIsAffirmed = (numApproachTypeID IS NULL),
bCommentsIsAffirmed = (parent.txtComments IS NULL)
FROM EngagementAuditAreas WITH(NOLOCK)

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.

In the "tblEmailGroupLink" table...
I need to find all records with the "UnSubscribed" field having a "True" value. All these records will have a corresponding "Emailid" field.
In the "tblEmailAddress" table...
The same "Emailid" field has a corresponding "EmailAddress" field.
What needed is all the email addresses found in the "EmailAdddress" field of these records.
I'm very new at this so I hope I explained this right. I'd really appreciate any help I can get.

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.

Here'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?

I have a database table with a primary key that auto-increments - using MS SQL Server 2000.
However I have another field (standard field) that must not allow duplicates.
Besides writing code to sift through the database every time to check for duplicates (which would take long to search through the db every time), is there any setting in MS SQL Server 2000 that allows for an automatic check for duplication and will prevent duplicates!??

Here's an example of what I mean...
PK Entry_Sheet Cust_Id Date

2 45663 cust6 16/11/2004
3 82917 cust1 16/11/2004
4 19283 cust2 17/11/2004
5 28764 cust2 18/11/2004
I have everything created, with data already in the table. What I need now is some way to prevent duplicates from occurring.
The Entry_Sheet value needs to be unique. Instead of writing code to run through the entire db each time an insert is performed, is there a simpler way using a SQL Server DB!??

where isdate(convert(datetime,date_stopped)) = 1
This won't work, I get the

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
