Now..When inserting data into TABLE B ,
->I need to check if the Attribute already exists in TABLE B .
-> If it already exists then I must update the Value feild with the latest value from TABLEA based on updated_datetime.
(Ex: Attribute 'A' already exists in tableB so i need to update the VALUE feild in TABLE B to 3.3 which is the latest updated value in TABLEA at 08:40AM)
-> If the Attribute doesnt exist then I simply need to insert that row into TABLEB
Can some one please post the query or the procedure that I can use for the above requirement.
Any help greatly appreciated.This is a urgent requirement for me.Please help
I have a table that contains a Ref field and a TransactionDate field. For each Ref field there are mutliple Transactions. I am trying to put together a query that selects the Latest Transaction date for each Ref field in the table.
I tried:
SELECT * FROM tabMediaTransaction WHERE (TransactionDate = (SELECT MAX(TransactionDate) AS Expr1 FROM tabMediaTransaction AS tabMediaTransaction_1))
But this only returns 1 record for 1 Ref field. I need 1 record for each Ref field
I have created the following SQL snippet that is a very simple mock-up illustrating the problem (I hope!) that I am facing:
-- create table if object_id('tempdb..#tmpdelnotes') is not null drop table #tmpdelnotes
create table #tmpdelnotes( DelNote int identity (1,1) , DelDate date not null, Item int not null, Customer int not null)
[code]...
What I need to retrieve is a unique list of item numbers with information about the latest (DelDate) delivery note. The "Clumsy workaround" works, but is not very pretty when doing multiple table joins. Is it really necessary to use a derived table for this kind of query? Window functions can only exist in the SELECT and ORDER BY clauses, which is understandable since the calculations take place (I would guess) after the aggregations in the HAVING clause.
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.

Hi People, hope someone can help me out here with a little problem. Basically i've go a asp.net page which has a listbox on. This list box is populated from a SQL database table with the datetime of the a selected field. Thus in the list box you get a list of strings looking like this "24/09/07 12:58" Also on the page is a submit button, and some other editing textboxes. The main issue here is the when the submit button is used i get the currently selected listbox timedate string and then pass this along with other items to update a record in the database based on the datetime in the listbox control.
Below is how i get the string from the listbox control Dim except_time As DateTime except_time = DropDownList1.SelectedValue The expect_time is then passed to store procedure along with some other vars, which looks like this -- =============================================-- Author: Lee Trueman-- Create date: 1st Sept 2007-- =============================================CREATE PROCEDURE [dbo].[spExcept_UpdateData] -- Add the parameters for the stored procedure here @validated bit, @update_time datetime, @except_time datetimeASBEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON -- Insert statements for procedure here UPDATE exceptions SET validated = @validated, update_time = @update_time WHERE (except_time = @except_time)END So validated and update_time should be updated when except_time is equal to @except_time
My problem is that the database never updates. If i debug the asp.net page the watch var shows the datetime in US format (I.e "09/24/07 12:58"), if this is true then this would explain why when it is passed to the stored proc nothing gets updated, as there would not be a date match. can anyone see any silly mistakes i'm doing here ????
I got some issues regarding selecting the most recent record from a datetime type column. The probelm consists in following: Table: News Needed columns: Letter [varchar] DateTimePublication [datetime]

Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar. Heres the code: DateTime createOn = DateTime.Now;string sSQLStatement = "INSERT INTO Index (Name, Description, Creator,CreatedOn) values ('" + name + "','" + description + "','" + userName + "','" + createOn + "')"; Any help would be much appreciated
Hey :)I'm facing a lot of troubles trying to create a new pause/break-system. Right now i'm building up the query that counts how many records that is inside 2 fields. Let me first show you my table: ID (int) | stamp_start (Type: DateTime) | stamp_end (Type: DateTime) | Username (varchar)0 | 17-03-07 12:00:00 | 17-03-07 12:30:00 | Hovgaard The client will enter a start time and a end time and this query should then count how many records that are inside this periode of time. Example: The client enter starttime: 12:05 and endtime: 12:35.The query shall then return 1 record found. The same thing if the user enters 12:20 and 12:50.My current query looks like this:SELECT COUNT(ID) AS Expr1 FROM table WHERE (start_stamp <= @pausetime_start) AND (end_stamp >= @pausetime_end)But this will only count if I enter the exact same times as the one inside the table.Any ideas how I can figure this out?Thanks for your time so far :)/Jonas Hovgaard - Denmark
Hi, I have a column of type datetime in sqlserver 2000. Whenever I try to insert the date '31/08/2006 23:28:59' I get the error "...datetime data type resulted in an out-of-range datetime value" I've looked everywhere and I can't solve the problem. Please note, I first got this error from an asp.net page and in order to ensure that it wasn't some problem with culture settings I decided to run the query straight in Sql Query Anaylser. The results were the same. What else could it be? cheers, Ernest
I am inserting date and time data into a SQL Server 2012 Express table from an application. The application is providing the date and time as a string data type. Is there a TSQL way to convert the date and time string to an SQL datetime date type? I want to do the conversion, because SQL displays an error due to the
My date and time string from the application looks like : 3/11/2014 12:57:57 PM

Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.
To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.
On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.
I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.
