Seeking Correct Syntax To Pass A NULL Value For A Datetime Field From An Asp Page To SQL
Jan 13, 2006
Hello,
I've been searching the web for quite some time to resolve the problem
of "1/1/1900" returning in a datetime field in SQL that resulted from a
blank (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 the
solution around it. HOWEVER, I can't seem to get the proper syntax to
work 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 have
tried, with the key part being the first section. Does anyone have any
suggestions?!?!?
______________
cDateClosed = ""
If(Request.Form("dateClosed")= "") Then
cDateClosed = (NULL)
end if
sql="UPDATE rfa SET "&_
"dateClosed='"& cDateClosed &"', "&_
"where rfaId='"& Request.Form("RFAID")&"'"
_______________
______________
cDateClosed = ""
If(Request.Form("dateClosed") <> "") Then
cDateClosed = (NULL)
end if
sql="UPDATE rfa SET "&_
"dateClosed='"& cDateClosed &"', "&_
"where rfaId='"& Request.Form("RFAID")&"'"
_______________
______________
cDateClosed = ""
If(Request.Form("dateClosed")= "") Then
cDateClosed = NULL
end if
sql="UPDATE rfa SET "&_
"dateClosed='"& cDateClosed &"', "&_
"where rfaId='"& Request.Form("RFAID")&"'"
_______________
Thanks in advance!!!!

I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits.
The mfg_start_date is delcared as a string variable
mfg_start_date = CStr(CDate(Mid(rs_get_msp_info(2), 3, 2) & "/" & Mid(rs_get_msp_info(2), 5, 2) & "/" & Mid(rs_get_msp_info(2), 1, 2)))
option 1
I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
With refresh_shipping_sched
.ActiveConnection = CurrentProject.Connection
.CommandText = "spRefresh_shipping_sched"
.CommandType = adCmdStoredProc
.Parameters.Append .CreateParameter("ret_val", adInteger, adParamReturnValue)
.Parameters.Append .CreateParameter("@option", adInteger, adParamInput, 4, update_option)
.Parameters.Append .CreateParameter("@mfg_ord_num", adChar, adParamInput, mfg_ord_num_length, "")
.Parameters.Append .CreateParameter("@mfg_start_date", adChar, adParamInput, 10, "")
Set rs_refresh_shipping_sched = .Execute
End
Please help

How can I pass into the database (@User_fax = null) if the fax form field is empty, from a command type Stored Procedure? For example:
Dim CmdUpdate As New SqlCommand("Form2_NewUser", strConnection)
CmdUpdate.CommandType = CommandType.StoredProcedure
CmdUpdate.Parameters.Add("@User_fax", SqlDbType.char, 9)
CmdUpdate.Parameters("@User_fax").Value = fax.Text()
...
strConnection.open()
CmdUpdate.ExecuteNonQuery
strConnection.close()
And, the stored procedure inside Sql server:
USE market1
GO
ALTER PROC Form2_NewUser
@User_id bigint, @User_fax char(9),...
AS
SET NOCOUNT ON
UPDATE Users
SET User_fax = @User_fax, ...
WHERE User_id = @User_id
SET NOCOUNT OFF
GO
Thank you,

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?

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:

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

Why does the following call to a stored procedure get me this error:
Msg 156, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'CONVERT'.
Code Snippet
EXECUTE OpenInvoiceItemSP_RAM CONVERT(DATETIME,'01-01-2008'), CONVERT(DATETIME,'04/30/2008') , 1,'81350'
The stored procedure accepts two datetime parameters, followed by an INT and a varchar(10) in that order.
I can't find anything wrong in the syntax for CONVERT or any nearby items.
Help me please. Thank you.

Hello I have a project that uses a large number of MS Data access pages created in Access 2003 and runs on MS SQL2005.
When I am on lets say my client, (first page in a series) data access page and I have completed the fields in the (DAP), I am directing my users to the next step of the registration process by means of a hyperlink to another Data access page in the same web but in a linked or sometimes different table.
I need to pass data entered /created on the first page to the next page and populate the next page with some data from the first page / table. (like staying on the client name and ID when i go to the next page)
I also need the first data access page to open and display a blank or new record. Not an existing record. I will also be looking to creata a drop down box as a record selector.
Any pointers in the right direction would be appreciated.
I am some what new to data access pages so a walk through would be nice but anything you got is welcome. Thanks Peter

Hi, I'm new to SQL and was wondering if there was an easier way to filter data.
I have two tables -
The first table called Names of Companies has a column named: NAMES
NAMES
XYZ Company
ABC Limited Liability Company
ZZZ Corporation
KKK Inc.
ABC Inc.
The second table called Keywords has a column named: WORDS
WORDS
Company
Limited
I want to search for all NAMES that contain the WORDS in some form
The results should be:
NAMES
XYZ Company
ABC Limited Liability Company
Technically, I can get the results I want by manually typing into the SQL statement all the words that appear in the WORDS column.
SELECT *
FROM [Names of Companies]
WHERE [Names of Companies].Names Like "*Company*" Or ([Names of Companies].Names) Like "*limited*"));
But is there a way that I reference the table Keyword instead of typing into the query statement all the words that appear in the column WORD? I have a lot of words to search for.
Can anyone recommend a better way to do this?
Thanks for all your help!

I'm trying to create a SQL job in SQL Server and am a little unclear about the formatting.Here's a snippet from the stored procedure that creates the job:CREATE PROCEDURE [dbo].[spArchive] @DB varchar(30), @Date DateTimeAS EXEC msdb.dbo.sp_add_jobstep @job_name = 'ArchiveIncentives' , @step_id = 1 , @step_name = 'ArchiveAHD' , @subsystem = 'TSQL' , @command = 'spArchiveAHD ''@Date''' , @on_success_action = 3 , @on_fail_action = 2 , @database_name = '@DB' , @retry_attempts = 1 In this case, the job will be calling this stored procedure:CREATE PROCEDURE [dbo].[spArchiveAHD] ( @dtArchiveBefore DateTime)AS I'm unclear about these lines: @command = 'spArchiveAHD ''@Date''' @database_name = '@DB' Do they look correct to you or should I drop some/all of the apostrophes?Robert W.

I have a test page where I'm using SqlConnection and SqlCommand to update a simple database table (decrease a number).
I'm trying to figure out how to make a number in the database table to decrease by 1 each time a button is being pressed. I know how to update the number by whatever I want to, but I have no idea what the correct syntax is for putting variables inside the query etc. Like "count -1" for instance.
The database table is called "friday" and the one and only column is called "Tickets".
Here's the code behind the button:protected void Button1_Click(object sender, EventArgs e)
{SqlConnection conn;
conn = new SqlConnection("Data Source=***;Initial Catalog=***;Persist Security Info=True;User ID=***;Password=***");
conn.Open();int count = -1;
SqlCommand cmd = new SqlCommand("select Tickets from friday", conn);
count = (int)cmd.ExecuteScalar();if (count > 0)
{
string updateString = @"
update friday
set Tickets = 500" ; <------ Here I want to set Tickets like "current count -1"SqlCommand cmd2 = new SqlCommand(updateString);
cmd2.Connection = conn;
cmd2.ExecuteNonQuery();
}
else
{
}
conn.Close();

I am having trouble finding the correct syntax to access a variable. I have a variable defined in the Variables window: The variable name is formatedDate. The DataType is String.
I am successfully setting the value of the variable in a Execute SQL Task. The SQL is as follows:
SELECT LEFT(CONVERT(VARCHAR, MAX(ReportDate), 120), 10) as formatedDate
from DimReportDates
The Result Set is set to “Single Row” and properly set up.
No problem so far. I can see with a watch that the variable has the correct value, something like:
‘2015-09-30’
Now, in a subsequent step, a Data Flow Task, I want to access the variable. Actualy it is in the SQL statement of a OLE DB source in the Data Flow… I have the following:
Declare @sDate smalldatetime
SELECT @sDate = xxxxx
I have tried several things substituting xxxxx above, but nothing seems to work. One variation was
@[User::formatedDate])
Another was
((DT_WSTR, 10) @[User::formatedDate]).
I think I’m close, but just can’t get it. What is the correct syntax.
