Adding Entry To DB And Getting Unique ID At The Same Time
Jul 20, 2005
Hi all,
I'm writing a website with Cold Fusion and when a user submits a
request and it's stored in the MS SQL database, I want the unique ID
(Identity field in table) to be given to the user on screen plus
emailed to user.
Now can I store data to the database (where the ID is created) and
return this as a variable in the same statement? I've seen this done
on many websites, but I have no idea how to do it in one step.
i am looking for code to show the last entry of a database that has a unique field. for eg.. i have columns AREA, NAME, NUMBER. i need to show the last entry for each unique area. so if there was 5 seperate areas, the table would show the last five entries for each area. anyone help?
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!
how to prevent the insertion of the same entry of an unique value into the database? assume that I have a primary key username " abc" in the database and then I insert the "abc" again ,the debuggging error msg pops out saying the primary key cannot be duplicated.. how can I do an if--else statement to check the database against this unintentional inputs of the same unique data " abc"???
I am trying to delet a row duing run-time but everytime i go to save the program I get an error message saying: "Update Requires a valid DeleteCommand when passed DataRow collection with deleted row.
A table gets data every 4 minutes, I only need spread of every 15 minutes. Can I select only records spread every 15 minutes apart from this table without having to run a scheduled job every 15 minutes and loading one record closest to getdate() at that point into another table(this is how I am doing it now) Is there a better way. Please help Thanks
Would anyone please instruct how to prevent the duplicate record bysetting the unique keys on the ms sql server? i've been checking theduplicate record as front-end and i found out if there is an internetdelay or some other reasons, it has a chance to store the duplicateddata into the database. so i realized it has to be done on the back-endside.for example, if i have three columns (office code, office id, officesection) as a unique key, how can i setup this? thanks in advance.
Hi, I have a doubt about the behaviour of SQL Server 2005 in the situation I'm going to describe you. Suppose that you have a SQL Server 2005 database on your PC, and suppose that this database has a table with a column classified as "unique" (so it's impossible for this table to contain 2 records having the same value in this column). Suppose that you publish this database and you create 2 SQL Server Mobile 2005 subscriptions on 2 Pocket PCs. Suppose now that the first PPC (using an embedded program) creates a record with a certain value for the column (and adds it to the table), and the second PPC makes the same thing (it inserts a record with the same column value of the first PPC). At this point, you connect the 2 PPCs to your PC (one by one, of course), to synchronize (using merge replication) the databases...
WHAT HAPPENS??? Does an error raise? Must you give a publication setting in which you say that, if this situation occurs, PC SQL Server holds the last (or the first, as you decide) record acquired? Is it possible?
I've googled everything about GUID, seems there is no good thing to say about it. Here's my scenario, a purchase order (PO) application:
We want to have a centralized database with remote sites connected to it
Some of the sites are without connection, they will have their own servers with scheduled replication to the centralized database. The design is something like this:
Each PO will have many revisions
Each revision will have many PO line items
Each PO line item will have many Delivery Schedules In the past i used int IDENTITY as transaction ID in revision and line item tables.
transaction ID in revision table is FK to line item table, and transaction ID line item table is FK to Delivery Schedules table.
This work well in standalone database.
Now that we need to merge replicates, int IDENTITY produced in remote DB will conflict with IDENTITY produced in central DB.
I'm thinking of using GUID to replace int IDENTITY.
Question:
How bad is my decision?
Can't GUID size indexing problem be solved with partitioning?
Can you suggest other alternatives to GUID, based on the above scenario? Thanks in advance
Hi, i am trying to add milliseconds to a time. For example if i have a time of 01:01:05:000 and i want to add 0.297 milliseconds to it i use the following simplified query
SELECT CONVERT(nvarchar(20), DATEADD(ms, 0.297, '00:01:05:000'), 14) AS Expr1
However instead of getting 01:01:05:0.297 i get 01:01:05:000. Can somebody please tell me what i am doing wrong.

I am trying to get a total for times, but I am having trouble gettinganything to work. Basically I created a query to pull up severalpeople's name that performed certain details and how long each detailwas. I now want to add up all the hours to a total for each person. Cananyone point me in the right direction?*** Sent via Developersdex http://www.developersdex.com ***
I have a shopping cart that will get full from time to time becausecustomers click out of the site before they confirm their purchase,therefore leaving a full cart behind. I'd like to have a timestamp onthis table, so that I can delete anything that I find is more than a dayold.How can I do this?Thanks,Bill*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
The sp "up_GetConfigurableDayInterval", will return number of days to add the the current date time. But print getdate() + @Id , is not producing the updated result.But when ever i have replaced the variable "@Id" with a value, Say "5", it is producing the expected result.I have also tested the above code by the following:-
create table Temp(value datetime); insert into Temp values(getdate() + @Id); select * from Temp
I know that I can add a column to a mining structure and/or model more than once using XMLA. However, I am having a problem doing the same using DMX. I now that DMX does not support data binding and that it relies on the INSERT INTO... construct to essentially map the structure columns to the incoming comluns from the data source. I tried to use "AS" like I would in SQL but it doesn't seem to like it.
Can anyone confirm that this can only be done using XMLA and not DMX? If I am mistaken, it would be greatly appreciated if you could provide an example on how to do this using DMX.
For background on why I would want to add the same column to a model more than once please read this post.
ID Date Time Length Interval_Num 1 10/11/2014 9:00 420 14
Basically, length represents the # of minutes a person is scheduled for. We have 30 minute intervals. Interval_Num = (Length/30). I need the data to show each interval. For the above example it should only be 14 intervals.For the above example the solution should look like....
ID Date Time Length 1 10/11/2014 9:00 30 1 10/11/2014 9:30 30 1 10/11/2014 10:00 30 1 10/11/2014 10:30 30
Hello all. I was just wondering how I could add the current date and time to the name of the .bak file. I perform a full backup daily and would like to keep a weeks worth of backups, but everytime I run the job, it just overites the previous one.
The command in the wizzard is:
BACKUP DATABASE [snl] TO DISK = N'C:Backups_for_FTPSNL_Full.bak' WITH NOINIT , NOUNLOAD , NAME = N'snl backup', SKIP , STATS = 10, DESCRIPTION = N'SNL Backup', NOFORMAT
I am trying to add the hours between each time block stored in a database.
In this database a user enters the begin time and the end time. For example the course MATH0001 would start at 8am and end at 10am. Therefore the user would enter 0810 in the start field and 1000 in the end field. The course MATH0001 doesn't run the entire semester it may only run from 8th Jan - 15th March and the course is scheduled in a room called GR4. Now because a course can be scheduled modularly, one room could have several courses scheduled in this manner.
The problem: I need to find out how many hours GR4 is used but it contains the following courses
A day only has 13 hours. Therefore the total hours spent in GR4 should be 12 hours. This is calculated by adding the hours between 8am and 5pm = 9 hours and 5pm an 8pm = 3 hours. I would not include 9am to 1pm because it is a subset of the 8am to 5pm slot.
Now, how to accomplish this but below is the code that i have thus far:
I forgot to mention that this code was to just test my 'final code' results and it outputs the table shown above. Anyway for testing purposes I have limited the search to the room GR4 and the day Tuesdays.
Code: select DISTINCT ssrmeet_room_code, ssrmeet_start_date, ssrmeet_end_date, ssrmeet_crn, ssrmeet_begin_time, ssrmeet_end_time, (((CAST(M.SSRMEET_END_TIME AS INT))-(CAST(M.SSRMEET_BEGIN_TIME AS INT)))+10)/100 As HoursPerClass,
I have a report which takes around 5 seconds when run in BIDS but takes around 20 seconds when deployed on report server.Execution log says TimeDataRetrieval is around 3-4 seconds and rendering time is around 15-17 secs.From this report I am passing 8 parameters to a drill through report and there are 36 text boxes where I have defined these parameters for drill through action.All these parameters are populated in main dataset.When I deployed the same report without any drill through action and parameter, it takes 5 seconds.So I am suspecting that because of drill through parameters report is taking more rendering time on server.I am using 2008R2 and IE11.
Is it expected behavior that due to so many parameters for drill through action, report will take more rendering time?If yes, then why is it not taking same time in BIDS?
If I just use a simple select statement, I find that I have 8286 records within a specified date range.
If I use the select statement to pull records that were created from 5pm and later and then add it to another select statement with records created before 5pm, I get a different count: 7521 + 756 = 8277
Is there something I am doing incorrectly in the following sql?
DECLARE @startdate date = '03-06-2015' DECLARE @enddate date = '10-31-2015' DECLARE @afterTime time = '17:00' SELECT General_Count = (SELECT COUNT(*) as General FROM Unidata.CrumsTicket ct

I have two columns in a table:StartDate DateTime and StartTime DateTime.The StartDate column holds a value such as 07/16/2004The StartTime column holds a value such as 3:00:00 PMI want to be able to add them in a stored procedure.When I use StartDate + StartTime I get a date two days earlier than expected.For example, instead of 7/16/2004 3:00:00 PM StartDate + StartTime returns7/14/2004 3:00:00 PM.Can anyone point out wht I'm doing wrong with this one?Thanks,lq
A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.
What's the difference in the effect of the followings: CREATE UNIQUE NONCLUSTERED INDEX and ALTER TABLE dbo.titles ADD CONSTRAINT titleind UNIQUE NONCLUSTERED
I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?
Hi everyone, I need urgent help to resolve this issue... As far as the performance goes which one is better.. Unique Index(col1, col2) OR Unique constraint(col1, col2) ? Unique constraint automatically adds a unique index and unique index takes care of uniqueness then whats the use of unique constraint ?
BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?
hi team, .Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today. Here is the code
Code Snippet create procedure SearchPartKeyword ( @Keyword varchar(250) = null, @Universal_Id varchar(10) = null ) as select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p inner join notes n on p.PartNumber = n.Identifier where n.Universal_ID = @Universal_ID and p.Description like @Keyword union select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly, p.DMM, p.Legacy, p.Folder, p.Printer from Parts p where p.Description like @Keyword
and the results: PartNo Description SO Notes LA DMM Legacy Folder Printer de90008 MAIN BOARD 1 DGF1 114688 0 0 0 de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0
This could return multiple part numbers and If they have entered notes I want the row with the notes
