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
We have a table that has customers invoices and payment records. In some cases a customer has 10 lines with 10 different invoice numbers but may have paid 2 or more invoices with one check. I need to know how many unique payments were made per customer.
I have a stored procedure that appends data from a temp table to a destination table. The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates. The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table? Thanks in advance.SMc
Need to remove the duplicated rows from a table which has text/ntext/image type columns. The table does not have any PK/Unique column. (I accept its a bad data model). But currently changing the data model is not possible. Hence doing changes in application.
I couldn't do 'SELECT DISTINCT * from table', since the table has text columns. Though there is no PK constraint, If I know that col1 and col2 are join PKs in the table, Is that possible to select the distinct rows from such a table.
I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:
Anna Smith John Doe
etc. I did not see IDs listed for any of the names in the table when I looked.
There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.
Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:
strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"
This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.
Is there a way to modify this statement to pull only the records that I want?
I have two tables that share a common identity row. I need to build a query where data that exists in one table does not contain data in the other table. For example, table 1 has columns of Owner_ID, LastName, FirstName and table 2 has columns Auto_ID, Owner_ID, AutoMake. Both tables are joined by the Owner_ID column. I need a query that provides all owners from table 1 who do not have an entry in table 2.
I have a query below to show all the records with joining these two tables.
SELECT DISTINCT B.BF_ORGN_CD, B.LEV5, A.BF_ACTY_CD FROM BF_ORGN A INNER JOIN BF_ORGN_CNSL_TBL B ON A.CD=B.BF_ORGN_CD WHERE A.BF_ACTY_CD IS NOT NULL ORDER BY B.BF_ORGN_CD,A.BF_ACTY_CD
My goal is only to show all the duplicate records.
Bf_ORGN_CD LEV5 BF_ACTY_CD AC_21234_2 AC_21200_1 402 AC_21236_2 AC_21200_1 402 AC_21238_2 AC_21200_1 402 AC_29000_1 AC_29000_1 802 ---> NOT SHOW (ONLY 1 RECORD) AC_29988_1 AC_29988_1 801 ---> NOT SHOW (ONLY 1 RECORD)
I am trying to use SQL to pull unique records from a large table. The table consists of people with in and out dates. Some people have duplicate entries with the same IN and OUT dates, others have duplicate IN dates but sometimes are missing an OUT date, and some don’t have an IN date but have an OUT date.
What I need to do is pull a report of all Unique Names with Unique IN and OUT dates (and not pull duplicate IN and OUT dates based on the Name).
I have tried 2 statements:
#1: SELECT DISTINCT tblTable1.Name, tblTable1.INDate FROM tblTable1 WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#)) GROUP BY tblTable1.Name, tblTable1.INDate ORDER BY tblTable1.Name;
#2: SELECT DISTINCT tblTable1.Name, tblTable1.INDate FROM tblTable1 WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#)) UNION SELECT DISTINCT tblTable1.Name, tblTable1.INDate FROM tblTable1 WHERE (((tblTable1.Priority)="high") AND ((tblTable1.ReportDate)>#12/27/2013#));
Both of these work great… until I the OUT date. Once it starts to pull the outdate, it also pulls all those who have a duplicate IN date but the OUT date is missing.
Example:
NameINOUT John Smith1/1/20141/2/2014 John Smith1/1/2014(blank)
I am very new to SQL and I am pretty sure I am missing something very simple… Is there a statement that can filter to ensure no duplicates appear on the query?
I have an incident reporting management application. People are supposed to report incidents by this application and every time some one reports an incident, they also select thier employee#(reqiured field). so how can write an sql statement that returns only the Top 5 incident reporters i.e going by employee number. Iam thinking of applying a COUNT function on the incident_id and grouping by Employee# but then how do i make sure that only the top 5 incident reporters are returned.
I have an unusual problem. I am using VB.Net 2003 and sqlexpress using .NET dataset to insert records into an timecards table. After inserting several records I tried a 'Select * from timecards' and the inserted records where not selected. if I 'select * from timecards order by employee' ( or any other field) the inserted records are selected! The table was created by an Access Upsize command.
I used Express Manager ( XM ) to try the select statements. That is how I isolated the problem. Even using a "Select * from timecards where employee = 'test' " returns the inserted test records. I found that if I use a WHERE or ORDER BY clause in the SELECT statement to .fill the .net dataset, all records are returned.
I am familiar with DB2 but I am a newbie at VB.NET and MSSQL
Both are related through vacation_id. Every vacation however has many pictures. I need a query where the result would give me back all records (vacations) from Table 1 with only 1 record from Table 2(one image per vacation).

Can Somebody please show me how to acheive this, using the order details in Northwinddatabase or any other good example. as much details as possible. Many Thanks!
My overarching goal is to generate sets of random Symptom records for each Enrollee in a drug study, so that for each cycle (period of time), the code will insert a random number of random records for each enrollee.
I'm trying to return a number of random records from a table, but inside a table-valued function... (which could be my problem).
CREATE FUNCTION dbo.ufn_GetTopSymptoms ( @enrollID INT , @CTCVersion VARCHAR(20) , @NumRecords INT ) RETURNS TABLE
[Code] ....
But that ORDER BY NEWID() clause is illegal apparently, because here's the error it throws:
Msg 443, Level 16, State 1, Procedure ufn_GetTopSymptoms, Line 13 Invalid use of a side-effecting operator 'newid' within a function.
I was hoping I could return a set of enrollmentIDs and then use CROSS APPLY to generate a random set of records for each enrollmentID... is this not possible with APPLY? I was trying to avoid using a cursor...
The idea is basically to create all the Symptom records for all the patients in treatment cycle at once by using Enrollee OUTER APPLY dbo.ufn_GetTopSymtoms(dbo.Enrollment.EnrolleeID)
but that's clearly not working. Is there a way to do this without resorting to a cursor?

Hi.I have a table (websitehits) which holds statistics about websites.This table has a date field (datecounted). What I need is to create aquery which returns a list of dates between two date ranges (say ayear ago from today and a year from now) which only shows dates thathaven't been used in the websitehits table for a given website.For example if my table contains something like:Website Datecounted HitsSite101/01/046000Site101/02/046500Site101/03/046250Site201/03/041000Site201/04/041200Site201/05/041500So if query for ‘site1' then I'd get a list of all dates between30/11/03 to 30/11/05 with the exception of the dates 01/01/04,01/02/04 and 01/03/04.So far I've tried to do this using another table named calendar whichcontains a very long list of dates and to use this to produce the list– but I'm not getting very far.By the way I'm using sql server, an I need this query to generate alist for an asp page - so I need to pass the website name as aparameter so I guess I need to make this query as a stored procedure.Does anyone know how this can be done?
I am trying to create a query to return the latest record from a dataset. The code created so far returns multiple records, where I need a single record to be returned.
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.
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've been searching and trying out SQL statements for hours and I'mstill having a problem.I'm querying 3 tables... and I only want the first unique recordreturned.Currently, the data returned looks like this..............New York New York ANew York New York BNew York New York CLos Angeles California ALos Angeles California BLos Angeles California CI want the select statement to return this instead...New York New York ALos Angeles California AI'm using MS SQL server.please help?thanks for your help.

I am making a program in Visual Basic .NET with SQL Server 2000.
I have a table "MyTable" with a primary key named "Id". The primary key is 'Create Unique' checked and 'Index' selected. When I insert all the fields required, except "Id" of course, I need the new record's "Id" in my VisualBasic program, but I don't know how...
I must do one of them, but don't know how either of them:
-Create a trigger on insertion that will send to the user that sended the insert command the "Id" of the record just created.
or
-get the command in Visual Basic that will send the Insert command with a return field ("Id")
As you can I have a uniqueidentifier (UniqueId) column which I populate with NewID() I'm trying to return this as I need it for other functionality of the website but I can't figure out how I can get it after the insert has completed?
Is there a way to get a Stored Procedure to return only unique records from a table? I am using a Stored PRocedure to query a table and it returns all the records in the table and there are many duplicates in the information. I am using SQL Server 2K.
SELECT COUNT(patient.patientID) AS total_patients FROM patient LEFT JOIN patient_record ON patient_record.patientID = patient.patientID WHERE sub_categoryID = 4 OR patient_record.allocated = 4
from the database this gives me a COUNT of 22, it should only be 10. I am doing a join and it gives the total records in the two tables where I only want the total in the left table(patient). How can I GROUP BY patient.patientID in a COUNT query
Hi ! I have a problem with the unique identifier and don't know how to solve it. I have a stored procedure, called from my ASP.NET page, which inserts a new record into a table. I need to get the Id of the row just inserted in order to use it as a parameter of another stored procedure which inserts a new row with this value and other values. I tried with SCOPE_IDENTITY but i don't know how to ask for this value to the first stored procedure and stored it into an ASP variable. Dim cmd As New SqlCommand cmd.CommandText = "Insertar_Contacto" cmd.CommandType = CommandType.StoredProcedure cmd.Connection = connect Thanks!!
Hello Everyone and thanks for your help in advance. I have a SQL Server Table wtih approximately 100,000 records. I need to determine if there are duplicate records in this table. My probelm is that there is a unique ID column that was added for each row, so I'm not exactly sure how to filter the rows. Any help on this would be greatly appreciated. Thanks.
