SQL Server 2012 :: How To Get Most Recent And Oldest From Joins To A Child Table
Jul 23, 2014
I have the following tables in my DB
Employee table - This table has EmployeeID, Name, DOB.
EmployeeDesignation table - 1 Employee can have many designations with each having an effective date. There is no flag to indicate which among multiples is the current entry. You can only figure it out by the newest/oldest EffectiveDate. I want to get the most recent and the oldest for each employee.
EmployeeSalaryHistory table - Structure/Design is similar to EmployeeDesignation table. I want to get the starting salary and current salary for each employee.
I want my query to output me the following fields...
Currently, I have a query to get this done which looks as below. Since I have more than 8K employees with each having multiple Designation and Salary entries, my query is taking forever.
selecte.EmployeeID, e.EmployeeName, e.EmployeeDOB,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate) EmployeeStartingDesignation,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate Desc) EmployeeCurrentDesignation,
I've 2 tables ResumeSkill (Child table) and Skill (Parent table), There are duplicates in the parent table and after removing the foreign key constraint in child table deleted all duplicate values from Parent table. But those deleted duplicate values has references in child table which need to be deleted now.
ResumeSkill Skill
Id SkillId SkillId Name
I want to delete all the records from ResumeSkill that dont have matching skillId in Skill table.
We have equipment table which stores Equipment_ID,Code,Parent_Id etc..for each Equipment_ID there is a Parent_Id. The PK is Equipment_ID Now i want to select the Code for the Parent_Id which also sits in the same table. All the Parent_Id's also are Equipment_ID's.

I'm playing with CTE and just want to expand my skills and ask how you would build this tree structure to fill that [Tree] column for table like in sample below:
/* CREATE TABLE #T1 (child_id INT, parent_id INT, tree VARCHAR(MAX))
I have table "Clients" who have associated records in table "Mailings" I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting. I'm trying to return records containing the next upcoming mailing for each client.
The closest I can get is below: I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date'
SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..
I have a table full of service invoice records. Some of the invoices are continuous, meaning that there may be an invoice from 01-16-2015 through the end of that month, but then another invoice that starts on feb 1 and goes for 6 months.
I want to only pull the most recent. Keep in mind that there may be other invoices in the same table for a different period. An example might be:
I need to get all customer records with the most recent tDate. A customer should never have duplicate tDate records, as only one record per day is allowed per customer, yet there somehow there are duplicates. Given this, I need to get the record with the Max date and Max ID. the ID column is an auto-incrementing Identity column.Below is the code without the Max ID column logic
SELECT tCustID, MAX(tDate) AS tDate--get MAX tDate records FROM table1 GROUP BY tCustID
Hi, I have a database that stores monthly nameed tables for historical data, but after a time (could be 1,2,3 months or on request) I need to be able to delete the oldest table. The tbale name format is ?????_mm_yyyy. Is there a MIN statement that could work on the create date? Any T-SQL statements that would help me on my way would be great Thanka!
I am building a application, which will generates a MASTER query with 15 fields & 5 tables joins.Now, the user selects only some fields from that master fields and generates the CHILD query. This is creating a performance issue.
To minimize this, i would like to remove the not necessary joins in the child query.
CREATE TABLE A (ID INT IDENTITY (1,1)) CREATE TABLE B (ID INT, EMPID VARCHAR(10)) INSERT INTO A DEFAULT VALUES GO 5 INSERT INTO B VALUES (1,'E23') INSERT INTO B VALUES (1,'E24') INSERT INTO B VALUES (2,'E23')
from the above code i would like to get output like
CREATE TABLE #tree ( Childid varchar(20), Parentid varchar(20) ) INSERT INTO #tree (Childid,ParentId) SELECT '123' , null UNION ALL SELECT '456' , '123' UNION ALL SELECT '789' , '456' UNION ALL SELECT '870' , '456' UNION ALL SELECT '985' , '870';
I have 6 tables which are very huge in row count and records needs to deleted which are older than 8 days.
Little info: Every day, 300 Million records are inserted in below 7 tables. we should maintain only 8 days worth of data in below tables. How to implement Purge script which can delete records in all tables in the same time and with optimized parallelism.
Master table which has [ID],[Timestamp] Table Name: Sample - 2,578,106
Child tables: Foreign key [ID] is common for all the tables. There is no timestamp column in child table. So the records needs to deleted based on Min(ID) from Sample
I've 2 tables QuestionAnswers and ConditionalQuestions and fetching data from them using CTE join and I'm seeing repetitive rows (not duplicate) like, If you have multiple answers for 1 question, the output is like
where london where paris where toronto
why us why japan why indonesia
I want to eliminate the repetitive question and group them as parent child items.
with cte as ( select cq.ConditionalQuestionID from ConditionalQuestions cq inner join QuestionAnswers qa on cq.QuestionID=qa.QuestionID where cq.QuestionID=5 and qa.IsConditional='Y') select distinct q.Question, a.Answer from QuestionAnswers qa inner join Answers a on a.AnswerID = qa.AnswerID inner join Questions q on q.QuestionID = qa.QuestionID inner join cte c on c.ConditionalQuestionID = qa.QuestionID;
I am working on a query that needs to return the record order number with the most recent requested delivery date.
It seems to work most of the time, but I have found some glitches for some of the items.
example is my item 10702, it is showing 2 records (both valid ones) Record 1 is order # 10450-0, requested delivery date 03/21/2014 Record 2 is order # 10510-0, requested delivery date 04/29/2014
I need to only get the records with the most recent delivery date, in this example that would be 04/29/2014
This query is what I have so far:
SELECT s.PriorQuoteNumber ,s.PriorItemNumber ,s.PriorQuoteDate FROM ( SELECT s.SalesQuoteNumberAS 'PriorQuoteNumber'
[code]....
WHERE s.rn = 1What am I missing in my query> how can I change it so it only returns the most recent date?
I'm using SQL Server 2005 along side Visual Studio 2005, using VB to create a web application at work. Now I'd like to bunch together some child fields in a gridview when displayed. Have a look at the attached pic to show what I would like.
Is this possible via a query or would I need to set something up on the gridview to do this?
I'm trying to create a stored procedure from a join of two tables. One table holds a list of containers, and the other table holds the history of the contents of those containers. All I want is to retrive the most recent history for each container. For example, the containers table has the container number and name, and the history table has the volume in the container and the date and time of the measurements. There can be any number of measurements, but I only want the most recent one.
Normally, I would just create a cursor that holds a list of the containers and some blank fields, and then loop through it, retrieving the most recent record one by one, but I don't know how to do that in Transact-SQL. Also, I thought maybe some SQL wizard out there might know of a way to do it with a simple select statement.
Given the Patients and PatientVisits tables as per below, how do I obtain the most recent (latest) Weight and Height for each patient as per http://www.hazzsoftwaresolutions.net/selectStatement.htm The result of the query should only return 3 rows/records,not 5. Thank you. Greg

I want to pick the recent modified date for DepCode and sum Yearly and Monthly Amount. I have tried this query and not able to get the output. This is the single table.
select B1.[ID], B1.[AppName], B1.[DepCode], B1.[DepName], B1.[Group], B2.ModifiedDate, B2.YearlyAmount, B2.MonthlyAmount, B1.[FuBded], B1.[AppCategory], B1.[Research] FROM Business B1 INNER JOIN (select [ID], MAX(ModifiedDate) as ModifiedDate, SUM(YearlyAmount) as YearlyAmount, SUM(MonthlyAmount) as MonthlyAmount from Business Group by ID) B2 ON B1.ID = B2.ID AND B1.ModifiedDate = B2.ModifiedDate
If I have a table structure similar to the following, how might I query it to obtain the Transaction ID, Transaction Date, and Customer Name for the most recent transaction per customer only:
TransactionTable: TransactionID TransactionDate TransactionType CustomerName 1 10/1/07 1 Bob 2 8/30/07 2 Janet 3 9/17/07 1 Mike 4 9/25/07 1 Bob
The following query will return all records in the table other than Janets...not what I want: SELECT Transaction ID, TransactionDate, CustomerName FROM TransactionTable WHERE TransactionType = 1 ORDER BY TransactionDate DESC
The following query will return all records in the table other than Janets again, because DISTINCT will use the combo of TransactionID, TransactionDate, and Customer name for uniqueness...not what I want: SELECT DISTINCT Transaction ID, TransactionDate, CustomerName FROM TransactionTable WHERE TransactionType = 1 ORDER BY TransactionDate DESC
The results set I'm looking for would be the following, where only the most recent entry per customer with TransactionType 1 is returned (i.e. one record for Bob):
TransactionTable: TransactionID TransactionDate CustomerName 1 10/1/07 Bob 3 9/17/07 Mike
I believe I need an appropriate subquery to yield the results I desire, but can't sort out what it is? I do not want to execute multiple queries but subqueries are fine. Unfortunately there's probably an easy answer that my brain is not currently generating. Any help would be appreciated.
Note, this is not a real table, but a sample to illustrate the concept for the query I need.
I have a query which contains 12 left outer join. I remove some of the joins that don't have parameters. The result is coming same but usually when we remove joining it should take less exec time but for me it is taking more time. What could be the reason?
The "Last" function in the query below (line 4 & 5) is not exactly what I'm after. The last function finds the last record in that table, but i need to find the most recent record in the table according to a date field.
Code: SELECT tblinmate.statusid, tblinmate.activedate, Last(tblclassificationhistory.classificationid) AS LastOfclassificationID, Last(tblsquadhistory.squadid) AS LastOfsquadID, tblperson.firstname, tblperson.middlename, tblperson.lastname,
[Code] ....
The query below finds the most recent record in a table according to a date field, my problem is i dont know how to integrate this Query into the above to replace the "Last" function
Code: SELECT a.inmateID, a.classificationID, b.max_date FROM ( SELECT tblClassificationHistory.inmateID, tblClassificationHistory.classificationID,
Empid 1 has 2 entries for the date 09/01/2015 and my left join returns both of those entries. What do I need to alter to make it so that only the most recent entry is returned not both entries?
Have a table that list item#, date the standard cost went into effect and the standard cost. How do I find the difference in StdCost on the last EffectiveDate and second to last EffectiveDate. 5.59 (01/05/2015) minus 5.81 (09/29/.014) = -.22.
I have set up an FTP connection that tests successfully. I can log on to the FTP site with the same credentials and see my root folder, and within that, two more folders. In my FTP task, I want to receive files to my local machine. The problem is that the only remote path available is not at the root level, and the only thing I can see are files from one of the child folders, but not the child folder I want.
Is it possible in the remote path to change folders? The remote path just shows a "/", which I thought would be the root level, but it is somehow linked to a child folder.I've tried various combinations to get to the folder I want, /root folder/child folder, but that gives the error that the folder does not exist.
If I open the FTP Task Editor, click on File Transfer, and click the ellipses for the Remote Path, the Browse For File box opens, with a "/" in the Location section, and a list of files in the child folder that I do not want to be in. If I click the "Up Directory" button, I get the message "Already at top level directory".
how I can get the files from one particular folder on the FTP site?
