We currently have an SQL db running on a web server.One of these fields is a large(ish) amount of text data – up to 400characters – and has been cast variously as varchar, nchar and texttype to overcome a problem. The problem appears to be in retrievingthe data via ASP. I understand that ASP can handle string data of thissize so I am okay there.When the records are retrieved from the db, the data string length =0.I know the data is there because I have written a Delphi data managerwhich interrogates the db and shows all records and their contents.So if ASP can handle strings this size and the data is there, why do Iget a data length of zero bytes returned when I interrogate the recordset?Whichever way I cast this field I get the same result.I know the code is sound as it works locally through a MS SQL serveron my PS.Anyone have this problem or know what's causing it? I have logged asupport call with my hosting company, but they haven't replied as yetand I am stuck on an urgent project.Any suggestions?CheersGrant
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? Moe
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?
How to replace DateTime field with null value in SQL 2005 server I create a stored procedure aa, It works well, but sometimes I hope to replace CreateDate field with null value,I don't know how to doIt seems that datetime type is not null value create aa @CreateDate DatetimeAsUpdate cw set CreateDate=@CreateDate
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
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 have a form that's filtering search results and porting to a gridview. The drop down is selecting from the date column of SQL, but i want it the default value to show all dates in the gridview. In a normal string field, you can just use "%", but a datetime field won't take this. What can i use to show all dates?
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?
I am trying to pull results from an SQL Server DB into an dataset where a particular field (SMALLDATETIME) is within a particular date range. The code I was using worked fine when the database was in Access. I have made several changes already but am still getting 0 results returned when there is data that should be returned.
I was using in Access: Dim StrSQL = "SELECT ID FROM myTable WHERE myDateField>=#" & startDate & "# AND myDateField<=#" & stopDate & "# ORDER BY ID" I have changed this for SQL Server to: Dim StrSQL = "SELECT ID FROM myTable WHERE myDateField>='01/01/2003 00:00:01' AND myDateField<='01/01/2004 23:59:59' ORDER BY ID" But I am always returned 0 results even if the date range should return plenty of data. I have also tried using the BETWEEN structure with the same result.
Is there a particular format for the date I am comparing with? Am I missing something else in my query?
The connection / permissions and everything else are correct as I can read and write data to the database in numerous other pages. It is just this date comparison that is not working.
Many thanks for any help or comments you can provide.
I have rows with a datetime column which spans many years. I am wondering is there a more simple way to select those rows where the datetime column is in a particular year. For example... where datetime_column.year = '2007'
I know i can use the 'between' sql etc...but am wondering if theres something more straightforward im not aware of.
I cannot in the life of me understand what goes wrong here... In a webapplication (C#.NET) I traced an inability to retrieve existing records to SQL Server, where I cannot do the same either. The problem is that in the parameterized query, some fields can be null, and thus when the corresponding fields in the database record are null also, they should be selected. But this won't happen for some reason.
I wrote a test SQL statement that gives me the same bogus:
DECLARE @institution int, @collection int, @serialnr int, @subnr nvarchar(50)SET @institution = 1 SET @collection = 1SET @serialnr = 240 SET @subnr = NULLSELECT ID, Institution, Collection, SerialNumber, SubNumber, AccessionYear, Sagsnummer, DanekraeNr, TaxonIdentified, Stratigraphy, TypeStatus, PlacementRoom, PlacementCabinet, PlacementDrawer, UnitNotesFROM SpecimensWHERE (Institution = @institution) AND (Collection = @collection) AND (SerialNumber = @serialnr) AND (SubNumber = @subnr) Now there is at least one row with corresponding fields values (1, 1, 240, null), but it won't be selected! What is wrong!?
I am trying to match records that are >= the current date. I have tried using: SELECT DISTINCT name FROM table WHERE datefield >= DATEPART(month, GETDATE()) AND datefield >= DATEPART(day, GETDATE()) AND datefield >= DATEPART(year, GETDATE()) ORDER BY name but this is not giving me the result that I am looking for. What is the best way to match a DateTime field type using the current date without the time?
Hello All,I've got a DATETIME field, and it includes hour:minutes:second data. I want to do selects where I can simply match on the month, day and year. For instance, something like this:SELECT * FROM QuizAttempts WHERE DateTimeTaken = '1/12/2006'And have it match anything that was taken that day, regardless of *when* it was taken. Any suggestions?Thanks! -Josh
Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar. Heres the code: DateTime createOn = DateTime.Now;string sSQLStatement = "INSERT INTO Index (Name, Description, Creator,CreatedOn) values ('" + name + "','" + description + "','" + userName + "','" + createOn + "')"; Any help would be much appreciated
The code below returns the members who have accounts that are inactive, and works correctly. It returns the memberid, but returns null values for the barcode values. I am explicitly looking for unmatched rows, i.e. the LEFT OUTER JOIN will return joined member-address rows which do not have a matching account, according to the ON conditions, and these are the ones I want because of that WHERE condition. Therefore account.barcode will always be NULL too.
Is there to perform the same query and return account details? I have tried running a query to return just the memberid values and then perform a second query to match the account details, but this is very ineffecient and slow.
select member.memberid, account.barcode FROM member INNER JOIN address ON address.MemberID = member.Memberid LEFT OUTER JOIN account ON account.Memberid = member.MemberID AND account.enddate >= current_date AND account.closed = 0 WHERE account.Memberid is null AND member.isDeleted = 0

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.
i have 2 stored procedures: a delete and a select. the delete sp returns the rowcount properly. the select returns null. the code for both sp's is extremely simple and extremely similar. when i execute the select sp in server management studio the rowcount shows a 1 as expected. but the calling method gets null. SP Code ALTER PROCEDURE [dbo].[RetrieveEmployeeKeyFromAssignmentTable] @assignmentPrimaryKey int, @rowCount int OUTPUT AS BEGIN SET NOCOUNT ON; SELECT employeePrimaryKey FROM assignmentTable WHERE primaryKey = @assignmentPrimaryKey; SET @rowCount = @@RowCount; END c# code SqlConnection conn = GetOpenSqlConnection(); if (conn == null) return true; SqlDataReader reader = null; SqlParameter p1 = new SqlParameter(); SqlParameter p2 = new SqlParameter(); try { SqlCommand command = new SqlCommand(); command.CommandText = "RetrieveEmployeeKeyFromAssignmentTable"; command.CommandType = CommandType.StoredProcedure; command.Connection = conn; p1.ParameterName = "@assignmentPrimaryKey"; p1.Value = assignmentPrimaryKey; p2.ParameterName = "@rowCount"; p2.Direction = ParameterDirection.Output; p2.Value = 0; command.Parameters.Add(p1); command.Parameters.Add(p2); reader = command.ExecuteReader(); if (p2.Value == null) //always true any suggestions would be appreciated. thanks. matt
I have a simple table on my webpage which shows data from my database. It all worked fine apart from one part. I wanted the select statement to select only NULL values from a column, as these are classed as open queries. Once I have closed the query a 0 or 1 will automatically be posted and will no longer have a NULL value. I have a simple select statement (which I will post on here when I log in with my work computer) and at the end I have a WHERE Column = NULL. I have also tried WHERE column <> 0.0 AND column <>1.0 and that did not work. If I only did WHERE column <> 1.0, i only get the 0.0 results and none of the NULL results, but if I have no WHERE statement I get all the results including the NULL values.
I have a table tblnetwork on which identity property is defined on column networkid.
When I issue the following command new record is getting inserted into tblnetwork and identity column is getting incremented properly. But, I am not able to get the @@identity value It is returned as NULL.
Using SQL2000. I want to return the # of columns with non-nullvalues. Here's my query so far:selectcase when Dx1 is not null then 0 else 1 end +case when Dx2 is not null then 0 else 1 end +case when Dx3 is not null then 0 else 1 end +case when Dx4 is not null then 0 else 1 end as DxCountfrom tblClerkshipDataCleanwhere PalmName = @PalmNameThere are 7 rows for the particular PalmName I'm using. The queryreturns a result of 7. However, there are 25 values in Dx1 thru Dx4so the query should be returning 25.What am I doing wrong here? Thanks in advance.
I have a SQL 2005 clustered server which is returning a Null value for @@servername. I find the server entry in sysservers. I have replication configured on this so i am not able to do a Sp_dropserver & sp_addserver as this acts as a publisher. The configured merge repication stopped working because of this issue and I am not able to delete replication as the the delete option uses @@servername which returns a null value. So I am struck in a loop.
