What Default Date To Use In Database Datetime Field

Aug 4, 2006

We want to add a default date to our database tables. Looking at other database samples people use all sorts of dates to add as default date e.g. 1/1/1997 or the getdate() function.

Is it good practice to set a default date and what should the default date be????

Default Field Value For DateTime && SmallDateTime

May 25, 2004

In SQL Server 2000 / Asp.Net I am trying to use default values for all fields; hoping to eliminate nulls.

For number and character fields, the default is pretty obvious, but is there any empty value for a date field? I think a null there might be better than putting in a bogus date, at least it can be tested for.

Are there any more developend ideas on this question?

Many thanks

How To Convert Datetime Field To A Date Field So Excel Recognize It As Data Type

May 17, 2015

I embedded a SQL query in excel that gets some datetime fields like "TASK_FINISH_DATE" .

How can I convert a datetime field to a date field in SQL in a way that excel will recognize it as a date type and not a text type?

I tried:
CONVERT(varchar(8),TASK_FINISH_DATE ,3)
CONVERT(Date,TASK_FINISH_DATE ,3)
CAST(TASK_FINISH_DATE as date)

**all of the above returned text objectes in excel and not date objects.

Informix Date Type Field To SQL Server Datetime Field Error

Oct 17, 2007



I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part

I tried a couple of things:

Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.

Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.

What options do I have that will work?

Datetime To Time Conversion With Default Date

Aug 2, 2007

Hi,

I am importing a csv file to SQL 2005 table. The source column is coming as datetime. The destination filed is a datetime type. I would like to update the destination with the time part from the source. I used the data conversion to convert it to time using "database time[DT_DBTIME]". For a source value "2/08/2007 21:51:07" this inserts a value "2007-08-03 21:51:07.000". I need the column to have a value as "1900-01-01 21:57:07.000".

Can someone please tell me how do I do this conversion?


Thanks,

Date From Datetime Field

Mar 11, 2004

Hi

What is the best practice to get the date from a smalldatetime field without the time.

The table contains 5 minute readings for energy consumption in the column period.

Now i need to get all the readings form some dates.

SELECT dbo.TBL_Data.*
FROM dbo.TBL_Data
WHERE (Period IN (CONVERT(DATETIME, '2003-12-31', 102), CONVERT(DATETIME, '2004-01-01', 102)))


this result contains only the readings for the timestamp 00:00

so how to select the whole day ?

kind regards

Getting Just The Date Or From DateTime Field

Sep 2, 2004

Hi,
I have used smalldatetime datatype to store my date and time values. i want to store just the date or time but the problem is it stores both the date and time. For eg, if i add the the date 03/11/2004, it also the stores the current time automatically. so the new value will be something like 03/11/2004 10:00:00 AM where i want just 03/11/2004. further problem is even though i managed to store just the date like 03/11/2004 in the database, whole date and time shows up when i display it in my pages.

any help will be appreciated.

thanx,

Get Date Only From Datetime Field!

Sep 3, 2007

OK, I know this is really simple but I can't get my statement to pull just the date from a datetime field!

Here's my query:

select *
from tblPR
where date between convert(datetime, dateadd(day,-day(getdate())+1,getdate()),103)
and convert(datetime, dateadd(day,-day(getdate()),dateadd(month,1,getdate())),103)

I get no errors but I get the timestamp too and I only want the date.

Where am I going wrong?!

Thanks in advance,
Brett

Select Only Date From Datetime Field

Mar 10, 2004

I know there must be a way to do this....

I want to select only the date portion of a datetime field. the date normally shows as similar to '2004-01-01 09:39:52.000'

I need to return just '2004-01-01'. using convert and cast returns the dates as 'JAN 01 2004' - this won't sort correctly, so it is of no use. any suggestions?

thanks,

Problem With Inserting Date In A Datetime Field

Apr 24, 2004

Hi, I have a problem when I insert a date in a datetime field in a MSSQLServer.
That's my problem:
if the server is in english version, I have to insert date with this code:

DateTime.Today.ToString("MM/dd/yyyy")

instead if the server is in italian version, I have to insert date with this code:

DateTime.Today.ToString("dd/MM/yyyy")

Is there a way to insert a date in standard way, without knowing the server version?

bye and thanks in advance

Querying DateTime Field And Summarize Just Using Date

May 9, 2012

I have 2 tables that I would like to summarize a couple of columns for a full day of production(12:00:00 AM to 11:59:59 PM) based on passed variables. Here are my Tables:

Order_Details_tbl
PlantID – IngredientID – AmountBatched – DateTime
1 – 8 – 1000 – 4/30/2012 1:23:12 PM
1 – 8 – 1000 – 4/30/2012 4:23:12 PM
1 – 8 – 1000 – 5/1/2012 1:23:12 PM
1 – 8 – 1000 – 5/1/2012 10:23:12 PM
1 – 8 – 4500 – 5/3/2012 1:23:12 PM
1 – 8 – 11000 – 5/7/2012 1:23:12 PM
1 – 8 – 1000 – 5/7/2012 10:23:12 AM
1 – 8 – 1000 – 5/7/2012 1:23:12 PM
1 – 8 – 1000 – 5/7/2012 1:23:12 PM
1 – 8 – 1000 – 5/8/2012 9:23:12 AM
1 – 8 – 1000 – 5/8/2012 4:23:12 PM
1 – 8 – 1000 – 5/8/2012 2:23:12 PM

Order_Details_Details_tbl
PlantID – IngredientID – AmountBatched – DateTime
1 – 8 – 100 – 4/30/2012 1:23:12 PM
1 – 8 – 11000 – 5/4/2012 11:23:12 PM
1 – 8 – 11000 – 5/7/2012 11:23:12 PM
1 – 8 – 1000 – 5/8/2012 11:23:12 AM
1 – 8 – 1000 – 5/8/2012 1:23:12 AM
1 – 8 – 1000 – 5/8/2012 11:23:12 PM
1 – 8 – 1000 – 5/8/2012 5:23:12 PM
1 – 8 – 1000 – 5/8/2012 2:23:12 PM

I will pass in the @PlantID int, @IngredientID int, and @Days int. I want to sum the AmountBatched from both tables and display the total for each given day. The @Days will indicate the number of days to query off of previous to the current date. I would also like to eliminate weekends from the results. For example when stored procedure is run passing the following values @PlantID = 1, @IngredientID = 8, and @Days = 14. If date procedure is run is 5/9/2012, would like to summarize for 4/25/2012 to 5/8/2012 excluding weekends if possible.

Results
Date – AmountBatched
4/25/2012 – 0
4/26/2012 – 0
4/27/2012 -- 0
4/30/2012 -- 2100
5/1/2012 -- 2000
5/2/2012 -- 0
5/3/2012 -- 4500
5/4/2012 -- 11000
5/7/2012 -- 25000
5/8/2012 – 8000

Notice 4/28, 4/29, 5/5, and 5/6 are eliminated from the results, which are weekends. Is this possible in a sql stored procedure? I am writing an app in vb .net and am hoping to get the results I need in a single call to sql server and not have to make several calls back. I have not worked with advanced datetime methods in sql server before.

Date Poition Comparison Of A Datetime Field

Jul 23, 2005

I have a datetime variable coming from my ASP.NET application that hasa time portion. I give my users the option to perform an equals,greater than, less than, or between comparison. The trouble comes inthe way the application builds the criteria string. The WHERE clausepassed in is in the format, "(start_dt = '2005/05/16 07:00:00.000')".What I want to do is only compare the date portion of start_dt to thedate portion of the passed in time. Manipulating the start_dt with thebuilt-in SQL functions isn't a problem, but altering the date passed infrom the ASP.NET would be a massive framework change in the app.Is there any way to only compare the date portions of both the SQLfield and the passed in value?Thanks.

Date Picker Bug - Drops The Default Value And Displays Default Value As Todays Date

Apr 3, 2008



Hi,
Does anyone have a workaround or know of a fix to this problem:
Default value set to 'date pick' from date currently within field by setting value equal to that field . ie if date is 01/01/2010 date picker opens in Jan 2010 - works ok.
However, once published to Sharepoint and run through browser the Date Picker ignores the default value and the date picker opens for today. ie April 2008.


Any words of wisdom gratefully recieved,

Updating Database Date Field Results In Date Value Of 01/01/1900

Brand new to this, so please bear with me.I'm using the following code fragment to update a datetime field on a SQL Server 2005 database table:cmd.CommandText = "Update Projects Set EntryDate = " & Convert.ToDateTime(txtEntryDate.Text)cmd.ExecuteNonQuery()The result of the update operation is the the database field contains the value "1900-01-01 00:00:00:000".  This probably means that I passed nulls to SQL; however, I see a valid date in the txtEntryDate field on my web form (i.e., "06/18/2007").  I also did a "Response.write" to display the txtEntryDate and it looks Okay.Can someone tell me what I'm doing wrong?Thanks!Using Visual Web Developer 2005 Express.

Automatically Update Datetime Field In A Database Table.

Feb 28, 2006

hi e'body:

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).

Inserting And Retriving Datetime Field In Database MSSQL 2000

Jan 10, 2006

Hi, Assume I have a table name "myTime". This table is simply only have 1 (one) DATETIME field "MyTestTime" (also serve as a primary number).Table MyTime- MyTestTime : SQLTYPE DATETIMETo insert a new row into this field, I simply wrote :SqlCommand sqlCommand = new SqlCommand("insert into MyTime values('2006-01-09')", sqlConnection);
I got the value of "2006-01-09" from a textbox or other relevan control.I realize when I try to use "SELECT * FROM MyTime" statement, MSSQL server 2000 automatically convert my date value from "2006-01-09" to "01/09/2006" (from YYYY-MM-DD to MM/DD/YYYY). I don't know why this one must be converted to MM/DD/YYYY automatically (I believe this behavior is depend on some "setting option" in my MSSQL server - but I don't know which one).The challenge is :In my country, the actual date format is like German Date format (DD-MM-YYY). Well I know this is only "Customization" problem. But how insert datetime value given from sql query to a datetime variable?// Connect to database, make a query, get the datareader result, and bla bla blaDateTime aDateTime = new DateTime;aDateTime = Convert.ToDateTime(myDataReader["PostDate"].ToString());// close connectionMy question isHow can I make sure that aDateTime's day is 09 not 01. How my program know that 09 is day not month. I can't use string.split() method because it's possible that my database setting will change from "mm-dd-yyyy" to "dd-mm-yyyy"thanks
