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
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 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!
I'm importing data form an Excel file to a Sql Server Database. Some of the data imported represents time as a double type so i convert the times into DateTime to be inserted into the database. The time values that aren't available in the Excel file are 0.. so what i want to do is insert null into the database for all the values that are 0 in the excel file... How do i do that based on this code i have so far:protected void ButtonImport_Click(object sender, EventArgs e){PanelUpload.Visible = false;PanelView.Visible = false;PanelImport.Visible = true;LabelImport.Text = "";OleDbCommand objCommand = new OleDbCommand();objCommand = ExcelConnection(); OleDbDataReader reader;reader = objCommand.ExecuteReader(); while (reader.Read()){DateTime? in_1 = null;DateTime? out_1 = null;DateTime? in_2 = null;DateTime? out_2 = null; int emp_id = Convert.ToInt32(reader["emp_id"]);DateTime date_entry = Convert.ToDateTime(reader["date_entry"]);if (Convert.ToDouble(reader["in_1"]) != 0)in_1 = ConvertDoubleToDateTime((double)reader["in_1"]);if (Convert.ToDouble(reader["out_1"]) != 0)out_1 = ConvertDoubleToDateTime((double)reader["out_1"]);if (Convert.ToDouble(reader["in_2"]) != 0)in_2 = ConvertDoubleToDateTime((double)reader["in_2"]);if (Convert.ToDouble(reader["out_2"]) != 0)out_2 = ConvertDoubleToDateTime((double)reader["out_2"]); ImportIntoAttendance(emp_id, date_entry, in_1, out_1, in_2, out_2);} reader.Close();}protected void ImportIntoAttendance(int emp_id, DateTime date_entry, DateTime? in_1, DateTime? out_1, DateTime? in_2, DateTime? out_2){ SqlDataSource AttendanceDataSource = new SqlDataSource();AttendanceDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["SalariesConnectionString1"].ToString();AttendanceDataSource.InsertCommandType = SqlDataSourceCommandType.Text;AttendanceDataSource.InsertCommand = "INSERT INTO Attendance (emp_id, date_entry, in_1, out_1, in_2, out_2) " +"VALUES ('" + emp_id + "', '" + date_entry + "', '" + in_1 + "', '" + out_1 + "', " +"'" + in_2 + "', '" + out_2 + "')"; int rowsAffected = 0;try{rowsAffected = AttendanceDataSource.Insert();}catch(Exception ex){LabelImport.Text += "<font color=red>" + ex + "</font><br />";} }private DateTime ConvertDoubleToDateTime(double dbTime){string[] SplitTime = dbTime.ToString().Split('.');string hours = SplitTime[0];string minutes = String.Empty;string time = String.Empty; if (dbTime.ToString().IndexOf('.') != -1){if (SplitTime[1].Length >= 1){if (SplitTime[1].Length == 1)minutes = Convert.ToString(Convert.ToDouble(SplitTime[1]) * 10);else if (SplitTime[1].Length > 1)minutes = SplitTime[1];}}elseminutes = "00";time = hours + ":" + minutes;return Convert.ToDateTime(time);}

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
I am update/inserting records threw a web form in vb.net. I need to insert 'NULL' into my microsoft sql server database. I am not talking about the below line of code where website is the name of my paramater. If i do that it will just place a blank into that field in the database. If i dont enter anything into that textbox I want it to to say NULL in that field. So if I go into the actual table in the SQL Server Management Studio and look at the website field of the recored I just added or updated and did not type anything into the web site textbox it needs to say NULL. I also tried the second line of code but that places a single quote in front and behind NULL. So the field will have the value 'NULL'.
website.value = txtwebsite.text.tostirng
if txtwebsite.text ="" then
website.value ="NULL"
end if
The reason why I need the NULL there is because I bind the website filed to a hyperlink template in a gridview. The actual text of the hyperlink is bound to PAYER which is a name of a insurance payer but the navigateto is bound to the website field. If i do not enter any data into the website field and it stays as NULL, then when my gridview is loaded, payers that dont have a website will not be underlined and user wont have the option to click on them since there is no value for the navigateto. But if i use my form to update/add a payer and leave the website textbox blank in puts a blank into that field in my database and when it loads that new row into the gridview the PAYER is underlined and u can click on it but it will just take u to the web site is unavailable page. So is there anyway to actaull have NULL placed into a filed and not just blank space
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!
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
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 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?
I found it rather hard to replace a string in an NTEXT field in sql server 2000. Would it be easier in SSIS 2005? Please advise. Thanks.

Hi,
I'm using this source code in order to set the DateTime field of my Sql Server database to null.I am retreiving dates from an excel sheet. If no date is found, then I set my variable myDate to DateTime.MinValue then i test it just before feeding my database.
I have an error saying that 'object' does not contain definition for 'Value'.
In french : Message d'erreur du compilateur: CS0117: 'object' ne contient pas de définition pour 'Value'dbCommand.Parameters["@DateRDV"].Value = System.Data.SqlTypes.SqlDateTime.Null;
The funny thing is that in the class browser i can see the Value property for the class Object...

I'm trying to find a specific string (a name) and replace it with another inside of a VARCHAR(7000) field. Unfortunately, there are names like Ted and Ken that I'm trying to replace. I would like to leave words like Broken, admitted, etc... intact.
UPDATEtbl
SETBody = LEFT(REPLACE(tbl.Body, pm.OldFirstName, p.FirstName), 7000)
FROM Table tbl
JOIN Person p ON p.PersonID = tbl.PersonID
JOIN PersonMap pm ON pm.PersonID = p.PersonID AND LEN(pm.OldFirstName) > 2
WHEREtbl.Body LIKE '%[^a-z]'+pm.OldFirstName+'[., ]%
'The problem I'm running into is that the '[, ]%' in the LIKE excludes any record that ends with the FirstName because it is requiring either a space, comma or period after the name. Is there some way to add an empty string to the list of acceptable characters as that would cover any scenario in the data? I would prefer not to add all characters except space, comma and period, but I guess I could do that.
If myDateTimeColumn contains a <NULL> value. How do you handle that when reading into a DateTime object in your code?DateTime myDate = Convert.ToDateTime(dr["myDateTimeColumn"]);Does not work, it throws: System.InvalidCastException: Object cannot be cast from DBNull to other types.
I am curious as to what others are doing to handle this?

I need to separate the data from one column in to two columns based on the transaction type TRAN_TYPE (C is credit, D is Debit)
TRAN-TYPE| AMOUNT
C 20.00
D 30.00
C 50.00
To do that I have this code:
select
CASE WHEN TRAN_TYPE = 'D'THEN CAST (ISNULL(amount, 0) as varchar (30)) end as DEBIT,
CASE WHEN TRAN_TYPE = 'c'THEN CAST (ISNULL(amount, 0) as varchar (30)) end as CREDIT
FROM HISTORY
And my output is:
DEBIT | CREDIT
----------------
NULL | 20.00
------|-------
30.00 | NULL
------|-------
NULL | 50.00
------|-------

I have the Person table with the following fields:
Id_Person
Nm_Person
Id_AddressResidential
Id_AddressCommercial
Another table called Address with the following fields:
Id_Address
Ds_Street
I want to make the relationship between these tables so that when deleting a related field address in Person is set to null.the SQL Server allows me to make this relationship in only one field.A person can live and work in the same place. If I delete her address, I want the two Individual fields are set to null.

Hello,
I have an Excel spreadsheet that contains 100,000 + rows of data. Two of the columns in the spreadsheet are date fields that are sent over in the yyyymmdd format (no separators such as "-" or "/"). I tried converting these fields into dates using the Data Conversion task in SSIS. This doesn't work as it appears that SSIS cannot map a string in the format of yyyymmdd to a valid date. In lieu of this, I have added a Script Component to my transformation which can take the string and convert it to a date value using some Substring() calls on the source yyyymmdd string.
A few questions for the group ...
1. Is this there a more efficient or "better" way of performing this transformation?
2. I can also use OLE DB Command task in my transformation and make a call that might do something like this: select convert(datetime, convert(varchar(10), [@yyyymmddValue])) but how would this perform related to the Script Component task? My guess is that this would be slower since the transformation would make a database call for every record.
3. Are there any plans for the SQL team to make these types of conversions easier to implement in the future? It seems to me that this is a pretty common scenario for integrating date data.
Thanks!

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.
