Performance Hit If I Use SELECT DISTINCT?
Mar 23, 2006
We use an ASP/MS SQL 2000 system to send out our mass e-mailing to about 3,500 subscribers (and the list is growing). There are some duplicate entries in the DB and I was thinking about using this code
SELECT DISTINCT email FROM Subscribers
to remove the duplicates (at least until we can get around to cleaning up the data and then putting up new subscriber form to prevent duplicate entries).
I was wondering, though... Will this have a significant impact on our performance? I mean, that's a lot of e-mail addresses to process and I don't want to bog our system down unnecessarily.
What do you performance gurus think?

Hi, I have the following script segment which is failing:
CREATE TABLE #LatLong (Latitude DECIMAL, Longitude DECIMAL, PRIMARY KEY (Latitude, Longitude))
INSERT INTO #LatLong SELECT DISTINCT Latitude, Longitude FROM RGCcache
When I run it I get the following error: "Violation of PRIMARY KEY constraint 'PK__#LatLong__________7CE3D9D4'. Cannot insert duplicate key in object 'dbo.#LatLong'."
Im not sure how this is failing as when I try creating another table with 2 decimal columns and repeated values, select distinct only returns distinct pairs of values.
The failure may be related to the fact that RGCcache has about 10 million rows, but I can't see why.
Any ideas?

Hi all,
I have a simple cube with only one measure : "Amount", I have three dimensions Supplier, Category and Company.
I would like to display a matrix with Categories as rows, company as columns, the amount and the number of distinct suppliers who appaers for each category/company.
I tried to create a calculated measure like this:
Count(Crossjoin({[D Supplier].[Supplier Code].members}, {[Measures].[Amount]}), EXCLUDEEMPTY)
The result is OK, but when I add this calculated Measure to my query the execution time jumps from a few seconds (<10) to a few minutes. Am I missing something ?
Anyone have an idea to do this in a better way ?

I have a problem where my users complain that a select statement takes too long, at 90 seconds, to read 120 records out of a database.
The select statement reads from 9 tables three of which contain 1000000 records, the others contain between 100 and 250000 records.
I have checked that each column in the joins are indexed - they are (but some of them are clustered indexes, not unclustered).
I have run the SQL Profiler trace from the run of the query through the "Database Engine Tuning Advisor". That just suggested two statistics items which I added (no benefit) and two indexes for tables that are not involved at all in the query (I didn't add these).
I also ran the query through the Query window in SSMS with "Include Actual Execution Plan" enabled. This showed that all the execution time was being taken up by searches of the clustered indexes.
I have tried running the select with just three tables involved, and it completes fast. I added a fourth and it took 7 seconds. However there was no WHERE clause for the fourth table, so I got a cartesian product which might have explained the problem.
So my question is: Is it normal for such a type of read query to take 90 seconds to complete?
Is there anything I could do to speed it up.
Any other thoughts?
Thanks

Is their a way to select all items from a table that are not distinct? Meaning, I want to know which items in a column occur more than once.
Example:
Suppose we have a table with student names, ss# and address. I want to display only records where their is more than one studen with the same name. So for example their could be ten people with the name of "Mike" in a class?

Hi! I have 4 tables and they have a common column (eg. regionid). These
4 tables have data overlapping with the others. Some data exist in a table
but not on the others. What I want to do is to do a select that will display
all distinct regionid from these tables. It should be total of all the tables but will suppress any duplicates with the others.
Note that UNION is working but I can't use that. Why ? because UNION is not supported or maybe not working properly with RDB database. I'm doing an appliaction for heterogenous datasource.
Any tips, hints or info will be appreciated.
thanks in advance.

Can you have "Select Distinct" in Union Query,because that is what I am trying to do and this is the error message I get.
"The text, ntext, or image data type cannot be selected as DISTINCT."
I would need to do that because i have duplicate records,because these records are getting written into the db when templates are generated and sometimes if they double click it generates two and writes that many results as well, so that is why I was thinking that select distinct would solve my problem.
Thanks for your help

I don't know what the correct syntax is to do what I want with the DISTINCTfunction (if it's actually possible).I have a query which displays a variety of fields from a variety of tables(pretty standard).However, I only want to show records where the contents of one particularcolumn in the query are unique - I do not want to perform the function onthe entire record because other fields in the records may be duplicated foras reason.

ex

1 2
1 1
2 1
3 3
3 3

Hi
Just a question
I have a query that selects profile data for members, if I don€™t do a select distinct it gives me a lot of correct values, (unique values) of members i.e. only one record per member, but every now and then I get duplicate values for one member, multiple times.
Why does this occure?
I know SELECT DISTINCT is there to remove duplicates, but without SELECT DISTINCT why would this €œmistake€? happen?
Any help would be greatly appreciated.
I.e.
2 | 3 | John | Slack | Philips |5
1 | 2 | Jason | Limrick | Jones | 3
1 | 2 | Jason | Limrick | Jones | 3
1 | 2 | Jason | Limrick | Jones | 3
1 | 2 | Jason | Limrick | Jones | 3
1 | 2 | Jason | Limrick | Jones | 3
2 | 3 | Jane | John | Parker |4
Why would it create duplicate records if the values are the same?
Kind Regards

where a.type like '%client%' and a.userfield1 is not null and (s.division like '%HR%' or s.division like '%db%') and s.type = 'client'
So what happens now is that if an account is listed in two division I get two distinct rows returned, but each with the same GID column. When I try to push this to a new database that has GID as the primary key I get duplicate on that column and it errors out.
I need to be able to get only a single row if the division is both HR and db. how to tackle this problem.

FROM ProductsToRelist I join Products P on P.ProductID = I.AppSKU
WHERE P.Relist = 1 and I.AppStatus = 5 and Not I.AppItemId is Null
and it returns something like this:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
1665 -30987 SELECT_OOS11
2433 -30987 SELECT_OOS11
4272 -30984 SELECT11
2436 -30984 SELECT11
2793 -32708 SELECT11
But I only it want it to return 1 record for each ProductID like so:
AppItemId ProductID PartNum Relist AppUserId
2786 -32730 SELECT_OOS11
2787 -32729 SELECT12
2788 -32727 SELECT_OOS11
4269 -30987 SELECT_OOS12
4272 -30984 SELECT11
2793 -32708 SELECT11
ProductID is the primary key for the Products table, and a product can be in the ProductsToRelist table many times but each row would have a unique AppItemId. I know that I need to use Distinct or a different kind of join, but I'm not sure which. How would you suggest to do this?
Thanks

Hey there, is there a way I can use command such as distinct in a select statement to do the following. Lets say I want to do a search of products based off their location and I want to list the companies that will have products in that area. I only want to list the company once, but if I’m searching by products in the area I might come up with 15 results for that company. I have not written the code yet for this, I’m just planning ahead.
I’m programming using VB so I guess I would do something like this.
State = Trim(Request.QueryString("State"))
SelectStatement = "Select * From Products Where State='" & _
State & "'"
This would of course give me hypothetically speaking a list as long as the amount of products in one given area. Is there a way to cut this down and only list the company once? Any help would be greatly appreciated. Thanks in advance.

I have the following tablecolumns: [col1], [col2],[col3] and [NAME].I want to select the name column for each row where [col1]='07'.The problem is that there are several rows where [col1] contains '07' and also the name is the same. [col2] and [col3] contain different data for these double rows...however, I cant use the [col1] and [col2] values in my query because I dont know what values they contain beforehand.So now, when I execute my query and add the DISTINCT key I still get all the double rows!I hope this explains my problem, help is really appreciated...ow, btw: deleting the double rows is not an option....

I have been trying to run a query using select distinct(column_name) on a column that is an nvarchar but the query still gives me all of the items including duplicates. I have removing any trailing spaces and still no good. Any ideas would be appreciated.
