Cant Insert NULL To DateTime Field
Jun 5, 2006
Hi I'm using DetailView and I have a text box which show the date. I have formated the date as shortDate {0:d} format. I want to insert/update null if that text box is empty.
I have tried putting null value in my Update statement in sqlDataSource. And I'm getting error saying can't convert varchar to smalldatetime.
If I don't set null value as above, some large date (01/01/2033) has been inserted in my database.
Can anyone help me?

I have a table adapter for one of my SQL2005 tables, and in two different fields I accept a date time. Now 99% of the times, new rows to this table will be filled out using DateTIme.Now(), as a Time Stamp is what I'm going for.
Here is the line of code in question...cops_current_data_adapter.Insert(ProductOrder, Convert.ToInt16(Session["StationId"].ToString()),
PartNumber, DateTime.Now, DateTime.Now, Convert.ToInt16(qty), 0);
The second DateTime.Now is the one that can be null, and it's throwing a formatting error everytime I try and drop it in there. It's a FormatException, and there's not much more to the example except unhelpful tips like be careful when conveting a string to a dateTime, which I'm not doing. Needless to say for the code to compile, and then throw a Format error at runtime is a bit frustraiting.
Any suggestions would be most appreciated

I have a datetime field in a database which I am programmatically inserting values into. The field can be null or not null. However, I am having problems inserting NULL as part of my SQLCommand.
The value is pulled from a text box (linked to a calendar extender) and when I select a value it is being inserted fine. If I just leave the box blank though, I want the field to be set to NULL. I have tried adding in ,DBNULL.Value, as part of my VALUES(…) string, but this throws an exception. I Have tried just inserting ‘’ but that also throws an exception (“The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value�), so I don’t know how I can insert this value when the field is blank?
Can anyone shed some light please? Thanks

I have defined fields in a table as datetime fields and allow nulls. SQL 6.5 is placing 1-Jan-1900 in all of these fields causing me to have to filter out these dates when retrieving a recordset.
How do I get rid of this?
thanks!

Hi there ;
This Problem is goin to make me crazy!
I've got a table with couple of fields, 2 of them are DateTime, in Sql Express 05 .
I used asp.net 2.0 to insert datetime values, directly, using sth like DateTime.Now.ToString() .
i use 2 selects as follows :
1)select * from X where Date1='8/9/2006 11:17:41 AM'
2)select * from X where Date2='8/9/2006 11:17:41 AM'
#1 is OK, but the second one returns a row with all columns set to NULL .
(X is the name of the table)
Thanks in advance

Hi
I have a really simple query which i can't figure out why its not working. I have a table called 'ADMIN' which has a datetime field called 'date_edited'. Because the majority of records have never been edited, i have allowed null values and they are filled with 'NULL' in each record. How ever, when i try:
SELECT * FROM ADMIN WHERE date_edited = NULL
I get no records, but i can see and know i have hundreds! I know i'm doing somthing really stupid, but for life of me can't figure it out! :eek:
thanks

There was a similar question to mine a few time ago about conditional execution, but I'm having some problems with it to which I couldn't find any answer, could anyone help?
My condition is checking if a DateTime from a DB table is null. I use the Execute SQL Task to retrieve the record (SELECT TOP 1 * FROM myTable WHERE conditions = TRUE), then I map 2 fields to their respective global variables.
Then I created the green arrow connector and used a precedence expression based on sucess. I used the expression IsNull(@variable). For some reason, even if the @variable comes as null - I checked the info in the DB - it still comes out as '1999-11-30'
I've looked around and the IsNull method can be used to also change the value in the event of it being null, could it be changing my variables value to this even if I didn't pass that value as a parameter to the function? If so, how else can I test it for null? I've tried "== null", "= null" and even ".equals(null)" - which I know is absurd, but I'm running out of options here...
Could you enlighten me, please???
Thanks in advance!

Hello,I've been searching the web for quite some time to resolve the problemof "1/1/1900" returning in a datetime field in SQL that resulted from ablank (not NULL) value being passed to it through an ASP page.The solution is that a NULL value needs to passed to SQL from ASP.Thats fine...I understand the why the problem is happening and thesolution around it. HOWEVER, I can't seem to get the proper syntax towork in the ASP page. It seems no matter what I try the "1/1/1900"still results. Below are a few variations of the code that I havetried, with the key part being the first section. Does anyone have anysuggestions?!?!?______________cDateClosed = ""If(Request.Form("dateClosed")= "") ThencDateClosed = (NULL)end ifsql="UPDATE rfa SET "&_"dateClosed='"& cDateClosed &"', "&_"where rfaId='"& Request.Form("RFAID")&"'"_____________________________cDateClosed = ""If(Request.Form("dateClosed") <> "") ThencDateClosed = (NULL)end ifsql="UPDATE rfa SET "&_"dateClosed='"& cDateClosed &"', "&_"where rfaId='"& Request.Form("RFAID")&"'"_____________________________cDateClosed = ""If(Request.Form("dateClosed")= "") ThencDateClosed = NULLend ifsql="UPDATE rfa SET "&_"dateClosed='"& cDateClosed &"', "&_"where rfaId='"& Request.Form("RFAID")&"'"_______________Thanks in advance!!!!

I am doing a temporary retro-upgrade right now. So, I know this isn't exactly in the scope of ASP.Net. Ordinally my posts are. However, I need a VBScript example of how to insert the Date only into the DateTime field of an SQL 2000 Server. By default, if you try to, the server automatically adds the date "1/1/1900".

I would like to be able to insert a time value only into a SQL 7 table colum which has been set as a datetime datatype. When I insert '12:34:44 PM' into the colum it actually inserts '1900-1-1 12:34:44 PM'. An Access table will allow you to insert the time value without adding the '1/1/1900' date value. Can this be done in SQL7?
Thanks for any help.

Hello everyone,
I am using DTS to transform data from foxpro.when it meets the date of NULL,it fails and says"Insert Error , column 4( 'Coloumn_name ',DBTYPE_DBTIMESTAMP), Status 6 data overflow ".
And then i try to open the DTS Transform Data task and do a preview of the data from the 'Source' side.The Null values are treated as "1899-12-30".
After reading something ,i try to write an ActiveX scripting Task to solve this problem using the function of "IsDate()",but it fails with exceptions.
Now I don't know what to do.could anyone give me some suggestion?Anything will be appreciated!ThankX in advance!

I am trying to perform a bulk insert in SQL Query analyzer. This is the Schema for my table:
Taxonomic_Units Table:
INT 4 tsn

CHAR 35 unit_name1
CHAR 1 unit_ind2
CHAR 34 unit_name2
CHAR 7 unit_ind3

INT 4 taxon_author_id
INT 4 hybrid_author_id
SMALLINT 2 kingdom_id
SMALLINT 2 rank_id
DATETIME 4 update_date
CHAR 3 uncertain_prnt_ind
I use the following SQL Statement to BULK INSERT:
BULK INSERT itis.taxonomic_units
FROM '<dir path to input file>/taxonomic_units.txt'
WITH
(
FIELDTERMINATOR = '|',
ROWTERMINATOR = '|',
KEEPIDENTITY,
KEEPNULLS
)
Here is a sample of a row that I get an error when it is processed through the above BULK INSERT statement:
50||Bacteria||||||||invalid||No review; untreated NODC data|unknown|unknown||1996-06-13 14:51:08.0||||1|10|07/29/1996||
The error is:
Server: Msg 4864, Level 16, State 1, Line 1Bulk insert data conversion error (type mismatch) for row 1, column 17 (initial_time_stamp).
Just to make things easier on anyone who tries to help me solve this problem, the field that causes my Bulk insert statement to choke contains the data: "1996-06-13 14:51:08.0". Why is this happening? Any thoughts on how to solve it? I have been scouring help articles all day with no resolution to this problem.

I have a function that updates a table in sql server
If a field is left blank I want the database field set to Null. I use:sqlCmd.Parameter.Add("@somefield, someintvalue) to pass all my values to the database.
if someintvalue is null I want to set @somefield to dbnull
How can I do this? I get errors if I submit a null integer when there is a foreign key constraint. What is the best way to handle this? should I just make all parameters objects? so that I can set them to DBNull.Value?
Also on a side note, when you are populating fields from a datatable, is there a better way to set the values (i.e. of a textbox) than cheking for DBNull before assigning?

I’m looking for feedback on the Best/Right way to Insert nulls into SQL dateTime field in SQL DB from a web UI textbox.
Option 1: Presently implemented:
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", System.Data.SqlTypes.SqlDateTime.Null, dtDateFollowUp.Text)
Although ithis does what is needed it generates the following inner exception
ParamValue {System.Data.SqlTypes.SqlDateTime} Object[System.Data.SqlTypes.SqlDateTime] {System.Data.SqlTypes.SqlDateTime} System.Data.SqlTypes.SqlDateTimeDayTicks
<error: an exception of type: {System.Data.SqlTypes.SqlNullValueException} occurred> Integer IsNull True Boolean
Option 2:
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", System.DBNull.Value, dtDateFollowUp.Text)
No exceptions, no problems that I have seen yet.
Option 3:
Dim dtNull As System.Data.SqlTypes.INullable
Dim dtFollowUpDate = IIf(dtDateFollowUp.Text = "", dtNull, dtDateFollowUp.Text)
No exceptions, no problems that I have seen yet.
Any advice would be greatly appreciated!
Thanks

Is there a way to adjust a date and time depending on the users locale before inserting into the database?
Users login in and their country of residence is stored in the database on signup. My server is in the US and I want to reset part of the users db record when it's the end of the day in their country so I need to enter the date and time into the db plus or minus the time difference, is there a function written to do this already or would i need to write my own?

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE

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

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?

Hi,
I have a report with datetime parameter which is required to be optional (there should be an option not to select this parameter which would cause in not narrowing result of this report by this parameter).
I used datetime parameter (to have the calendar control for selecting date) for which I enabled NULL value. The result is that next to this parameter there is a checkbox "NULL" which allows to send NULL as a value of this parameter. Everything is fine except for the prompt: "NULL"... Is there a way to change it? I would see there something like "Empty" or "Not selected", which would be understandable for users of the report.
Or is there any other way to send an empty date as a value of this parameter? (Setting some unusual value like 1/1/1900 for empty date is not sufficient as the empty value shouldn't appear in the parameter control).
Thank you,
Michal
