Transact SQL :: Only Store Datetime Values Down To Nearest Minute Automatically Without Using Trigger
Sep 25, 2015
Is there a way that I can do this at the table level to automatically handle the rounding of seconds, etc. down to the minute automatically without having to use a trigger?
Here is a very basic example of what I am trying to do:
--example: '09-22-2007 15:07:18.850' this is the value inserted into the table by the code
select getdate()
--example: '2007-09-22 15:07:00.000' this is the value I want to store in the table
select dateadd(mi, datediff(mi, 0, getdate()), 0)
I just need the date, hour, and minute...not the micro seconds. Do I have to DATEPART and concatenate each or is there any way to simply truncate the milliseconds from it? Or is there a date format to put extract and report on it as...
I found in another forum that if I take the seconds and divide them by 15 then round up and multiply them by 4 I can get this done, but I can't figure out how to work it into my select statement. Anyhelp would be greatly appreciated. dbo.SLPTRANS.TimeSpent is the field I am trying to convert.
SELECT dbo.SLPTRANS.ClientID, SUM(dbo.SLPTRANS.TransValue) AS Expr1, dbo.SLPTRANS.TimeSpent AS Expr2 FROM dbo.SLPTRANS INNER JOIN dbo.INVOICE ON dbo.SLPTRANS.InvoiceID = dbo.INVOICE.RecordID GROUP BY dbo.SLPTRANS.ClientID HAVING (dbo.SLPTRANS.ClientID = 405)
I have such a scenario: - two tables with record containing car vehicle number, datetime of message and other data like weight ect. - first table contains only two messages for one car per one day - second has many messages for one car for one day
I would like to get a list of messages from first table but joined with the nearest (previous) record for the same car from second table.
Right now the database I am working with is storing time inan Integer data type and is storing the time value in seconds.The application does not allow entering seconds. It acceptsminutes and hours.I have a report where it is doing:SELECT SUM(TIMEENTERED)and the SUM is *blowing* up as the SUM is reachingthe BIGINT range.I can fix the problem by changing all codes to:SELECT SUM(CAST(TIMEENTERED AS BIGINT))But now that I ran into this problem I want to find outif storing the time in seconds using INTEGER datatype is the best solution?I've been searching this newsgroup and other placesthe whole day. I even ran into my own three year oldpost. Three years ago my problem was data migrationrelated and now it is more of performance related thananything else.http://groups.google.com/groups?as_...y=2006&safe=offI could not find this specific topic in SQL books likeSQL for Smarties 2005 by Joe Celko (very good stuff ontemporal topics but nothing specific to my question),or Inside SQL Server 2000.Which data type would be ideal and why?smalldatetime?integer?decimal?float?The type of operations that are being done in the databaseare:1- Entering time in hours on work done on a taskFor the data entry part, the application accepts2.5 as 2 and a half hours and it is storing2.5 * 3600 = 9000 seconds.It also accepts entering 2:30 as 2 hours and30 minutes and again storing 9000 seconds.I even saw a page where you can enter clocktime: I worked from 9:30AM to 12:45PMas an exampleWhen i checked the underlying table(s) I sawthat the ENTEREDTIME is always the durationin seconds. So the data entry can either be2.5 hours where ENTEREDTIME = 9000 secondsor9:00AM to 11:30AMwhere STARTDATE is today's date for examplestored as 1/27/2005 09:00AMand where ENTEREDTIME = 9000 seconds2- All kinds of reports showing total time in hoursfor example: Project1 = 18.5 hoursThe code in the SP are all like:SUM(ENTEREDTIME) / CAST(3600 AS DECIMAL(6,2))AS TOTALTIME3- I am sure a lot of other arithmetic calculations arebeing done with this ENTEREDTIME field.What would be the best way to store hours/minutesbased on how we are using Time in the database?Either I will stick with Integer but store in minutestime instead of calculating in seconds and most likelyupdate all the SUM(ENTEREDTIME) toSUM(CAST(ENTEREDTIME AS BIGINT))or I will switch to storing in decimal/float andmaybe avoid doing :SUM(ENTEREDTIME) / CAST(3600 AS DECIMAL(6,2))AS TOTALTIMEsince the ENTEREDTIME would already be storedin hours time.or I will use DATETIME since in the cases ofI worked from 9:00AM to 11:30AMI have to have a separate column to store the date also.I am a little confused I am hoping I will get some helpfrom you and maybe if I can't find the best solution, atleast eliminate the NOT so good ones I am thinking of.Thank you
Is there any non-obnoxious way (eg: without have to result to using datepart a million times) to do this? For instance, Oracle provides a function called Trunc which does it, but I cannot find an SQL Server equivalent. Anyone? TIA!!!
What I'd like to do with the sample query above is take an AVG for one hour for the values ZNT, SAT, RAT, RH...like I stated the records are every five minutes in the table, I'd like to create 60 minute AVGs.
I have configured an alert like below to track all blocked events in SQL Server across all databases and then kick start a sql job when a blocking happens which inserts data to a table, when there is a blocking in SQL server , i get an email --which is working fine and i am able to track all queries.
but, HOW to get notifications ONLY if BLOCKING IS HAPPENING FOR MORE THAN 30 SECONDS OR 1 MINUTE with out using sp_configure?
---ALERT USE [msdb] GO EXEC msdb.dbo.sp_update_alert @name=N'Blocking Process', @message_id=0, @severity=0, @enabled=1,
We have data that consists of an employee number, a start time and a finish time, similar to the example below
EMP STARTTIME ENDTIME
00001 10-Feb-2012 06:00:00 10-Feb-2012 10:00:00
00002 10-Feb-2012 07:15:00 10-Feb-2012 10:00:00
00003 10-Feb-2012 08:00:00 10-Feb-2012 10:00:00
I am trying to come up with a procedure in SQL that will give me each 15 minute block throughout the day and a count of how many employees are expected to be at work at the start of that 15 minute block. So, given the example above I would like to return
Hi, I'm inserting a datetime values into sql server 2000 from c#
SQL server table details Table nameate_test columnname datatype No int date_t DateTime
C# coding SqlConnection connectionToDatabase = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=testdb;Integrated Security=SSPI"); connectionToDatabase.Open(); DataTable dt1 = new DataTable(); dt1.Columns.Add("no",typeof(System.Int16)); dt1.Columns.Add("date_t", typeof(System.DateTime)); DataRow dr = dt1.NewRow(); dr["no"] = 1; dr["date_t"] = DateTime.Now; dt1.Rows.Add(dr); for(int i=0;i<dt1.Rows.Count;i++) { string str=dt1.Rows["no"].ToString(); DateTime dt=(DateTime)dt1.Rows["date_t"]; string insertQuery = "insert into date_test values(" + str + ",'" + dt + "')"; SqlCommand cmd = new SqlCommand(insertQuery, connectionToDatabase); cmd.ExecuteNonQuery(); MessageBox.Show("saved"); } When I run the above code, data is inserted into the table The value in the date_t column is 2007-07-09 22:10:11 000.The milliseconds value is always 000 only.I need the millisecond values also in date_t column. Is there any conversion needed for millisecond values?
I have some database tables, and each one of them have a creation_date and modified_date in them. I was trying to figure out a way where when a row in one of these tables is changed using Enterprise Manager (Database -> Tables -> select table -> right click -> select all rows -> change a field in a row inside a table), is there a way apart from triggers, such that the "modified_date" column for that row get changed to 'getdate()' (rather picks up the current datetime).
hi, i have 2 tables where i require an unique ID over both. I googled a bit and discovered that i need to create an own table for this which holds the last value (because mssql unfortunately does not support sequences).
i did this but my problem now is that i want to automatically set the id of my tables with a trigger on INSERT.
hope this is possible .. or anyone have other suggestions? thanks a lot!
I am new to SQl Server, i have created a logical model for a database that i am creating for a project. Is there a way i can assign automatic values to my Primary Key (PK) Column other than using an identity?
For example i have a table called indicator for which the Primary Key (PK) is indicator_identifier; i want the primary key values to be ind_0001 ind_0002 ind_0003
Please note that i may be populating the tables from a VB.NET form
Hello, I am using SQL Server 2005 and ASP.NET 2.0. We have a very simple content management system where we have to keep track of date last modified for each row in all of our content tables. I know there's a "timestamp" datatype that is used for replication scenarios, but is there anything similar that I can use to set up a date_modified column for each of my content tables that will automatically update with GETDATE() whenever anything in a given row is updated? Or do I have to create a date_modified column of smalldatetime datatype and write a trigger on update for EVERY single table of content that I have in the database? It seems there should be an easier way to do this than to write 20 triggers for my 20 content tables. Thanks!
I'm trying to update (increment) Company.SumtotalLogons from CompanyUsers.NumberOfLogons where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
I am building code to look into the database and create "CRUD" stored procedure scripts automatically for each table. I am in the finishing stages as my procedures take into consideration all necessary parameters and keys wheter they are natural or identity. It also takes into consideration User Defined Types.
I am working on the section which defines the parameters and their default values. ie. CREATE PROCEDURE [dbo].[TransactionHistoryInsertOne] ( @ProductID Int = 0, @ReferenceOrderID Int = 0, @ReferenceOrderLineID Int = 0, @TransactionDate DateTime = '1/1/1900', <-- Possibly arbitrary @TransactionType nchar(1) = '?' <---- How to get this. @Quantity Int = 0, @ActualCost Money = 0, @ModifiedDate DateTime = '1/1/1900' ) AS...
I have three problems remaining. 1. Using the AdventureWorks database as a data model, I run into the TransactionType field in the TransactionHistory table, a non-nullable nchar(1). How do I determine and use any default values that may be defined for this object? 2. Do UDTs have default values already defined? 3. How do I make sure I am not arbitrarily setting the default values?
Here i my select statement into the system tables:
SELECT C.*, T.name as xtypename, U.name as xutypename, S.*, so.* FROM syscolumns C
left join systypes T on (C.xtype = T.xtype) and (T.xtype = T.xusertype) left join systypes U on C.xusertype = U.xusertype left join sys.all_columns S on (C.id = S.object_id) and (C.name = S.name) left join sysobjects so on S.default_object_id = so.id WHERE (C.id = [TableId])";
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task. In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful. Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.
I have created a report, and am setting default values for the parameters. Once the default parameters is set, the report automatically generates. Is there a way to make it not automatically generate the report? We are setting the parameters with values that will get the end user the most recent data, but alot of times, they will want to pull older data as well. We don't want them to have to wait for the report to automatically generate before they can change the parameter values
I have a question about adding a unique key column to an existing table.
what i trying to do is that: I have already created a table, now i wanna add a ID column to this table, and generate the values for ID column from 1 to the existing row number. How can I get this done?
Hi frdz, I m creating my web-application in asp.net with C# 2005 and using sql server 2005. I have created the stored procedure for the insert,update.

I have an existing MS SQL database (2008 R2). I have a very simple SQL script. I need to automate this script means wants to create a job which runs on a Friday basis and save the output results of the query as a excel file and then automatically sends the mail to everyone.
I have to use the above comma separated values into a SQL Search query whose datatype is integer. How would i do this Search query in the IN Operator of SQL Server. My query is :
declare @id varchar(50) set @id= '3,4,6,7' set @id=(select replace(@id,'''',''))-- in below select query Id is of Integer datatype select *from ehsservice where id in(@id)
But this query throws following error message:
Conversion failed when converting the varchar value '3,4,6,7' to data type int.
Hi, I tried entering this value "8/24/2006 1:35:00.127 PM" with 127 as the milliseconds in a datetime field, but encountered error saying inconsistent datatype ... Anyone knows how to store datetime value with milliseconds in the SQL database? Thanks
I want to store time into a datetime datafield in MS SQL Database, but eventually, it was include a date prefix the time ! I had try the approach on following and get the invalid result.
Approach 1: Dim strTime as String = "11:59:59 AM" Output: 01-01-1900 11:59:59 AM
Approach 2: Dim dtTime as DateTime = "11:59:59 AM" Output: 1/1/0001 11:59:59 AM <- (error occur: unable add to DB cause date is not between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM)
* The time on the above is accompany with AM/PM.
Approach 3: Dim strTime as String = "11:59:59 AM" Dim strStartTime2 = DateTime.ParseExact(strStartTime, "hh:mm:ss", System.Globalization.CultureInfo.CurrentCulture) Output: 01-01-1900 11:59:59 AM
Approach 4: Dim strTime as DateTime = "11:59:59 AM" Dim strStartTime2 = DateTime.ParseExact(strStartTime, "hh:mm:ss", System.Globalization.CultureInfo.CurrentCulture) Output: String was not recognized as a valid DateTime.
I know what cause the approach 4 get an error. That is because the strTime is declare as DateTime and that contain "AM/PM" in time.
My Question: 1]Can I just insert the time only to the DB without date? 2]If possible, what should I delcare in the variable(String/DateTime/..?) 3]How can I deal with the "AM/PM"? It must concate with time to identify daytime/night
If you know and have the solution, pls do me a favor and will be more appreciated. Thank you
