Jun 4, 2014

I have 3 tables:


bigint NewId
nvarchar NewTitle
datetime NewDate

int CatId
nvarchar CatName

bigint Id
int CategoryIdFk
bigint NewsIdFk

I want to select NewId, NewDate and Distinct NewTitle

I tried this but NewTitle doesn't distinct:

FROM dbo.Category INNER JOIN
NewsRelCategory ON dbo.Category.CatId = NewsRelCategory.NrcCategoryIdFk INNER JOIN
dbo.News ON NewsRelCategory.NrcNewsIdFk = dbo.News.NewId

T-SQL (SS2K8) :: Selecting Top 1 From Multiple Ranges?

Mar 28, 2014

I have data like the following:

1 10 BLAH
1 20 BLAH
2 10 BLAH
3 10 BLAH
2 20 BLAH
2 30 BLAH

What I want to return is:

1 20 BLAH
2 30 BLAH
3 10 BLAH

I want the top 1, having the highest counter from each ID. This is a highly simplified version of that I am pulling which also is between a date range, but same principle.


I'd rather keep it in one statement if possible, but if I have to do it in multiple passes then so be it.

Selecting On Multiple Tables

Aug 13, 2006

Hi there,I'm new to sql and thus I'm having problems with a specific query which Ihope you guys can help me with.Basicly I have a few tables which I'm trying to do a query on:Table groups contains information about specific groups e.g. "Windows" or"Unix".Table users contains information about specific users e.g. "a", "b" or "c".Table users_groups contain information about group relationship (a user canbe in multiple groups) e.g. (a, Windows), (b, Unix), (a, Unix).In this case user c is ungrouped.Now I'd like to find the users which does belong to group Windows and thosewho do not:select distinct username from users_groups where groupname = "Windows" orderby username asc;This works pretty well for finding users in the specific group. In this casethe result is a.However I'd like to get the opposite result (b and c) but I'm stuck.The problem is that I'd like a list of all users excluding those which arein "Windows"Here is a partial query:select distinct users.username from users left join users_groups onusers.username = users_groups.username where users_groups.username is nullorder by users.username asc;This only gives me those users who are not grouped at all. This mean thatuser b is not in those results.Please advise.Thanks in advance.-- Henrik

But this does not work.

Transact SQL :: Distinct By One Column By Selecting Multiple Column?

Jul 17, 2015

I have a SQL Query issue you can find in SQL Fiddle


My query was like this

For Insert
Insert into Employee values('aa', 'T', 'qqq')
Insert into Employee values('aa' , 'F' , 'qqq')
Insert into Employee values('bb', 'F' , 'eee')
Insert into Employee values('cc' , 'T' , 'rrr')

Insert into Employee values('cc' , 'ZZ' , 'bac')
For select
select col1,MAX(col2) as Col2,Max(Col3) as Col3
from Employee
group by Col1

I supposed to get last row as 

    cc  Zz  bab

Instead I am getting 

  cc  Zz  rrr 

which is wrong

Selecting From Multiple Tables Avoiding Duplicates

Sep 6, 2006


I currently have two tables called Book and JournalPaper, both of which have a column called Publisher. Currently the data in the Publisher column is the Publisher name that is entered straight into either table and has been duplicated in many cases. To tidy this up I have created a new table called Publisher where each entry will have a unique ID.

I now want to remove the Publisher columns from Book and JournalPaper, replace it with an ID foreign key column and move the Publisher name data into the Publisher table. Is there a way I can do this without duplicating the data as some publishers appear several times on both tables?

Any help with this will be greatly appreciated as my limited SQL is not up to this particular challenge!!!

Transact SQL :: Distinct Values From Multiple Tables?

best way to go about this. My query works great and displays the information I require.

EG all demographic for ED, IP & OP. However if a patient has a record in each of the tables then I get the same info multiple times.

What I'm trying to do is a Select Distint against the entire query (below).

eg Select Distinct * from all below.

DECLARE @StartDate datetime = '01 oct 2015';
DECLARE @EndDate datetime = '30 OCT 2015';

Database Design Selecting Multiple Different Child Tables

Sep 19, 2000

I want to have a linking table say for example we call this a claim. Based on the claim number you need to relate to one of say 6 different types of claims. The types of claims related to their own individual parent table. (individual because each type of claim tracks completely different information) does anyone have an idea on how to set this up?

Sample Structure

table = Claim
Field 1 = ClaimTypeA_ID
Field 2 = ClaimTypeB_ID
Field 3 = ClaimTypeC_ID
Field 4 = ClaimTypeD_ID
Field 5 = ClaimTypeE_ID
Field 6 = ClaimTypeF_ID

The six field relate to the 6 different tables ID.

If I do this how do I store the data? put 0's in each of the claim types that are not used???

Any suggestions would be appreciated.

SQL Server 2012 :: Row Counts Based On Distinct Values From Multiple Tables

Jan 15, 2015

I am trying to create a query that outputs the following data from multiple tables. Here is an example of the raw data right now

Date | MachineNumber | TestName
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 500 | Something
1/1/2015 | 510 | NewTest
1/1/2015 | 510 | NewTest
1/1/2015 | 510 | NewTest
1/1/2015 | 620 | Test#1

Here is the desired counted output, I would like to pull distinct Date, MachineNumber, TestName and then count how many times they occur in the raw data form.I do need to perform a case on the date because right now its in a datetime format and I only need the date.

Date | MachineNumber | TestName | TestOccuranceCount
1/1/2015 | 500 | Something | 4
1/1/2015 | 510 | NewTest | 3
1/1/2015 | 620 | Test#555 | 1

I am pulling three columns with the same names from 8 different tables. What I need to display the date, machine & test name and count how many times a test was run on a machine for that date. I have a feeling this can be handled by SSAS but haven't built an analysis cube yet because I am unfamiliar with how they work. I was wondering if this is possible in a simple query. I tried to set something up in a #Temp table. Problem is the query takes forever to run because I am dealing with 1.7 Million rows. Doing an insert into #temp select columnA, columnB, columnC from 8 different tables takes a bit.

T-SQL (SS2K8) :: Get List Of All The Tables Used In Multiple Scripts

Aug 28, 2015

I am trying to figure out an automated way to get a list of all the tables used in a set of 275 T-SQL scripts. i do not want to go through each script manually, look at all the from clauses and write down the tables used.

I have managed to get all the 275 scripts into a table on SQL Server 2008 R2 database. one column per each script, so there are 275 rows in the table.

FYI: each query can have multiple result sets, so multiple from clauses can exist.

For Example:

Query 1 = SELECT * FROM Table1 a
INNER JOIN Table2 b ON b.Field = a.Field
LEFT OUTER JOIN Table3 c ON c.Filed = b.Field


SELECT * FROM Table4 a
INNER JOIN Table5 b ON b.Field = a.Field
LEFT OUTER JOIN Table6 c ON c.Filed = b.Field

Desired Output = Table1, Table2, Table3, Table4, Table5, Table6

Select DISTINCT On Multiple Columns Is Not Returning Distinct Rows?

Jul 6, 2007

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?

Selecting Distinct

Jul 18, 2007

 Hi, This is quite an obvious problem, but for some reason I can't think through the solution. I have two columns, a datetime (datecreated) and an id (FK)  othertableid (id)what I would like to be able to do is select a list of id and datecreated, but only chose the latest row for each id.So I guess it's a bit like a distinct on the id column, but ensuring the date returned is the top date. Please help

Selecting Distinct Rows

Jun 11, 2008

I want to select the 8 most saled products from large orders table... the problem is that when i use the "distinct" sentence (something like this- "SELECT TOP 8 distinct id, products, productid FROM tbl_orders ORDER BY id") I get back the distinct of any columns.... (and any ID is distinct, of course), but if i don't include the id's in the distinct sentence, i can't order by id's.
 can i get the last orders, only by distinct product, and not by distinct id, and order them by the id's?

I have an SQL statement that looks like the following:

SELECT [Docs-Entities].entityID, entityName, COUNT([Docs-DocsEntities].filename) AS numDocs
FROM [Docs-Entities] LEFT JOIN [Docs-DocsEntities]
ON [Docs-Entities].entityID = [Docs-DocsEntities].entityID
GROUP BY [Docs-Entities].entityID, entityName

but the problem is that numDocs (the COUNT) is not returning a distinct count. In the DocEntities table, a particular document can actually have multiple entries with the same entityID so that produces inflated numbers for numDocs. But when I do a SELECT DISTINCT on a particular entityID, the results are less and don't match the numDocs number because I only need to list the document one time. This is not a huge issue, but it looks bad on my site.

Is there a way that I can make COUNT count distinctly?

Thanks for the help and I hope I worded that cllearly...

Selecting A Distinct Row Query

May 13, 2004

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?

Help With A Query (Selecting Distinct Rows As Well As How To Use NOW())

Jan 16, 2008

Hi All,

I'm a beginner in SQL and would like some help with writing a query that needs to:

a) Return the latest time that an event happened (along with the event), and also

b) Determine if this event occurred more than 30mins ago.

For example, Table EVENT consists of the following data:

EVENT DateTime,

A 16/1/08, 14:03:55

B 16/1/08, 14:30:27

A 16/1/08, 17:42:18

I would like the results for the first part of query to be:

EVENT DateTime,

A 16/1/08, 17:42:18

B 16/1/08, 14:30:27

I have tried creating a query based off this thread, but for some reason it kept complaining that the EVENT column in Table EVENT didn't exist.

For the part b), I have no clue as to what I should do apart from that I would need to use NOW().

Any help would be appreciated.

Selecting Distinct Top 3 Rows From Database Using Join

Jun 25, 2007

Hi guys,

Just trying to select a set of Articles from a SQL Server Database. The Articles all have a Category ID which is stored in another table (as an Article could be in more than one Category). I want to select the Top 3 Articles in a Category. At the moment I have as my SQL;

"SELECT TOP 3 f.ArticleID, f.Heading, f.Summary, f.WrittenDate, f.ArticleURL FROM feedTable f LEFT JOIN Categories c ON f.ArticleID = c.ArticleID WHERE c.CategoryID=" + CategoryID + " AND c.ArticleID<>" + id + " ORDER BY c.CategoryID"

Which seems to work to an extent in that I do get three articles in the same Category appearing. However, there are sometimes duplicates appearing, so I need to incorporate a DISTINCT clause to the above. I'm not sure where to put this in though. Any ideas?
