Getting Distinct Entries In Query.
Mar 18, 2008
Hello,
I have a reference table. This table has an effective date and end date, and I need to get a single set of values at a point in time. Suppose the following hotel rating values are the values that I want to pull out of the table:
1 Star
2 Star
3 Star
4 Star
5 Star
This value has other information associated with it (benchmarks and such) and so it's possible that one of the 2 star entries gets end-dated, and then a new 2 Star entry gets created with an effective date and no end date.
How can I query so that I only get one 2 Star entry at any point, and get the point in time where the date is between the effective and end date, but only pull back a single set of entries, one distinct rating value. So, suppose the first entry is end-dated 7/1, if I look at old data, I want to see the old benchmarks and so I want the previous entry end-dated 7/1; otherwise, I want to see the new end-date, with the new 2 star entry with no end date.
How do I do that? Make sense?

I need to update the result depending upon the count of distinct entries.
Example
ID Employee Region State
1 ABC AMEA MI
2 DEF AMEA MI
3 XYZ APAC TX
I want the result as below
ID Employee Region State
1 ABC AMEA MI-1
2 DEF AMEA MI-2
3 XYZ APAC TX
since the count of Region is 2
I tried using DECLARE @intFlag INT and stuff but wasn't able to get the solution.

I need a query to return the number of distinct call_num(s) between two timestamps.
For example search between 2008-04-17 05:00:00.000 and
2008-04-19 05:00:00.000
Calls
----------
id_tag(unique id) | status | call_num | entry_id(timestamp)
1 HOLD 0123456789 2008-04-17 05:07:00.080
2 ONSCENE 012345679 2008-04-17 05:10:00.012
3 ENROUTE 321654987 2008-04-19 04:00:00.000
so the sample answer would be : 2

I need to run a SELECT DISTINCT query acrossmultiple fields, but I need to add another field that is NON-DISTINCTto my record set.Here is my query:SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, genderFROM gpresultsWHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis query runs perfect. No problems whatsoever. However, I need toalso include another field called "admitdate" that should be treatedas NON-DISTINCT. How do I add this in to the query?I've tried this but doesn't work:SELECT admitdateFROM (SELECT DISTINCT lastname, firstname, middleinitial, address1,address2, city, state, zip, age, gender from gpresults)WHERE age>='18' and serviceline not in ('4TH','4E','4W')and financialclass not in ('Z','X') and age not in('1','2','3','4','5','6','7','8','9','0')and (CAST (ADMITDATE AS DATETIME) >= DATEDIFF(day, 60, GETDATE()))ORDER BY zipThis has to be simple but I do not know the syntax to accomplishthis.Thanks

I have a database being populated by hits to a program on a server.The problem is each client connection may require a few hits in a 1-2second time frame. This is resulting in multiple database entries -all exactly the same, except the event_id field, which isauto-numbered.I need a way to query the record w/out duplicates. That is, anyrecords exactly the same except event_id should only return one record.Is this possible??Thank you,Barry

If I wanted to search for Jobs as a particular status (e.g. 0130) and wanted to keep the jobs at this status until it has reached 0500, 0125, or 0900 in it's subsequent status log entry, how can I write the SQL for it to achieve it?
I have the following SQL which searches for the Jobs at 0130, but don't know how to develop it further to search on the requirement above.
------ SQL -------
SELECT
job.job_number,
(SELECT MAX(jsl.job_log_number)
FROM job_status_log jsl
WHERE
job.job_number = jsl.job_number AND
jsl.status_code = '0130') as Last_Early_Warning_Status_Entry
[code].....
In the job_status_log table above, there is a job_log_number field which increments by 1 when there is a new status log entry.

I need help with a query on a single table.
The table in name, date, ss# and I need to get unique rows, but there can me many ss# to each date. I need to get the max date for each unique ss#.
Select distinct name, date, ss#
returns all rows, because dates are different, but I need to have the results contain all three columns of information.
Thanks for the help,

I'm kind of newbie and I like to know if you can solve me a question,
The fact is I'm trying to gather some information and I don't know how. What I want to do is retrieve the values of five columns, the first one is the primary key, but the others must be unique (all together)
PK Value1 Value2 Value3 Value4
1 3 5 6 3
2 3 5 7 2
3 4 3 1 4
4 3 5 6 3 <- =PK1

FROM (SELECT DISTINCT MesuraA, MesuraB, MesuraC, MesuraD
FROM barres_Ciampalini) AS derivedtbl_1
But I don't know how to retrieve the Id.
How Can I do that?

I have what I thought should be a simple query that's not quite as simple as I thought. Maybe I haven't had enough coffee yet.
Here's the scenario,
Data table looks like this :
COLUMN A is Primary Key
COLUMN B is UserID
COLUMN C is (for example purposes) an int field
A B C
1 1 SOME VALUE
2 1 SOME VALUE
3 1 SOME VALUE
4 2 SOME VALUE
5 2 SOME VALUE
6 2 SOME VALUE
7 3 SOME VALUE
8 3 SOME VALUE
9 3 SOME VALUE
The query that I'm looking for would return all 3 columns but only the first row for each distinct (unique) UserID (Column B)
Hope that all makes sense! ;)

I am trying to append data from a source table to a destination table, the only difference between the tables is that a primary key has been established on the destination table. Problem is, the source table has a handful of duplicate values in the column that corresponds to primary on destination table; so when I run the query I get a primary key conflict. What I'd like to do is select distinct values from the source table to avoid the conflict, but am having trouble getting it to run. Here is the statement-
INSERT INTO cust_master
SELECT DISTINCT cust_master_temp.*
FROM cust_mast_temp LEFT OUTER JOIN
cust_master ON cust_master.temp.CUST_NUMBER = cust_master.CUST_NUMBER
Doesn't seem to be understanding "Distinct"
Any Ideas?

I have a problem with a SQL SELECT query. As far as my research goes i figured out that UNIQUE is used when you have one column that you whant unique and DISTINCT is used when you have more than one column that you want to all be unique. But i have a query where i want just some of the columns to be unique and some not. Here is the full query (It's in a stored procedure):
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[rpt_ExecSum_Combined_4fields](@BondGroupID int)
AS SELECT DISTINCT
SUM(dbo.Bond.LoanAmount) AS SumOfBondValue, COUNT(dbo.Bond.BondID) AS CountOfBond, dbo.ProgressStepType.ProgressStepType
FROM dbo.BondGroup INNER JOIN
dbo.TransactionTable ON dbo.BondGroup.BondGroupID = dbo.TransactionTable.BondGroupID INNER JOIN
dbo.Bond ON dbo.TransactionTable.TransactionID = dbo.Bond.TransactionID INNER JOIN
dbo.ProgressStep ON dbo.TransactionTable.TransactionID = dbo.ProgressStep.TransactionID INNER JOIN
dbo.ProgressStepType ON dbo.ProgressStep.ProgressStepTypeID = dbo.ProgressStepType.ProgressStepTypeID
WHERE (dbo.BondGroup.BondGroupID = @BondGroupID)
GROUP BY dbo.ProgressStepType.ProgressStepType, dbo.ProgressStep.ProgressStepID
HAVING (dbo.ProgressStepType.ProgressStepType = 'AIP (Approval in Principle) received') OR
(dbo.ProgressStepType.ProgressStepType = 'Grants') OR
(dbo.ProgressStepType.ProgressStepType = 'Attorney') OR
(dbo.ProgressStepType.ProgressStepType = 'Feedback received from bank')
ORDER BY dbo.ProgressStepType.ProgressStepType
*********
With the DISTINCT it gives me a full set of unique values but what i want is this: Every CountOfBond may have more than one SumOfBondValue and they may be the same, but if there is more than one dbo.ProgressStepType.ProgressStepType the query should only read it once. In other words the dbo.ProgressStepType.ProgressStepType is a unique value and the rest not...
Please help, my boss is on my case :)

I need p.phonenumber in there but then it messes up my DISTINCT ON m.number because I end up with dup m.numbers if I run just the inner select statement during testing.
But then I need the phonenumber in that subquery so that I can do list.phonenumber
ahh!
UPDATE Master
SET master.homephone = list.phonenumber
FROM MASTER m
INNER JOIN
(SELECT DISTINCT p.number, topphone.phonenumber
FROM phones p
INNER JOIN (SELECT top 1 phonenumber from phones) as topphone ON topphone.number = p.number
WHERE p.phonetypeID = 1
AND ISNULL(p.good, 0) <> 0
AND LEN(p.phonenumber) = 10
) AS list ON m.Number = list.Number
WHERE m.homephone IS NULL OR m.homephone = ''
Error:

Incorrect syntax near the keyword 'top'.
Msg 156, Level 15, State 1, Procedure Skiaa, Line 88

I want to update m.homephone with the p.phonenumber based in the filtering critiria I have specified but this simple task is turning out to be a pain.
