I already asked this question; however, I am giving all the details
now:
We get large files(millions of records) and we need to load it into our
tables using import export wizard. Some of the fields in the file can
be Null and so we are forced to create table with fields that allow
Nulls with default ''. However when we insert data into these tables
it puts Null in those fields even though we have a default '' (I do not
think we have any work around for that; do we?)
Finally we need to go through each field and update it to '' if it is a
Null and that takes LOT OF TIME.
If (select count (*) from <tablename> where <columname> is Null) >0
Begin
Update <tablename>
set <columnName> = ''
where <columnName> is Null
end
Please let me know if there are any work arounds for this crisis ?
Thank you very much in advance!
Using asp.net 2.0 and visual studio 2005. The question is regarding the following ER diagram: I've made Firstname, lastname, buildingID and RoomNum all required fields. I've got a modified GridView that displays all of the table Faculty columns. It's been modified so the BuildingID and DepID are resolved to their actual field names and displayed in a DropDownList. In the dropdown list I used for inserting (a seperate DetailsView control), I manually inserted an item into the Department dropdownlist which had the text "-- Select a Department --" with a value of -1. MS SQL didn't like that -1 value so I wrote the following code to fix it: protected void dsFaculty_Inserting(object sender, SqlDataSourceCommandEventArgs e) { if (e.Command.Parameters["@DeptID"].Value.ToString() == "-1") { e.Command.Parameters["@DeptID"].Value = null; } } That means of course DeptID is null, which is ok. The problem arises is when I try to edit that row in the GridView. I get the an error 'ddlDepartment' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: valueIdeally, I'd like to make the dropdown list in the GridView show "-- None --" for the DeptID if it comes across a null value. I already tried playing around with the Command.Parameters in the dsFaculty_Selected function, but it didn't work. Ideas?
Hi all I am trying to populate a page with data from a SQL DB however one field is null. The problem is this is causing a StrongTypingException and I am not sure how I should handle this to stop the apllication crashing. I am trying to assign a bit value from a SQL Db to checkboxI have tried putting if (Convert.IsDBNull(contentRow.pag_status) == false){//Do what I want} but this still throws the exception Can anyone help!?
I have welders who have active dates and inactive dates, and I need to create an "isactive" column in the report. My formula will be pretty obvious to most of you. However, if the user does not input an inactive date, that means none has been given and therefore the welder is currently active. The problem is that there seems to be no way to check if inactive date is null or not in the formula.
Hi, In my Excel file, The Application date column contains empty for some rows. In SSIS I am using one Data Conversion to that Application Date column to change it as Date[dt_Date]. This data conversion is giving error Conversion failed. In Sqlserver table, I declare ApplicationDate column datatype as DateTime. I want to keep those empty date values as Null in Sqlserver. I tried the IMEX=1 property still it is not working. How to solve this error?
I have a web application. In some instances, I have a need to send guid parameter as null while making a sql query to SQL 2005. My question is as how to handle this null guid on .net and sql side. Thanks! in advance.
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 have a checkbox on my webform that is bound to a bit field in my SQL table. I'm fine as long as I've got the bit field set to 0 or 1, but if the field is NULL, the checkbox throws an exception during the databind.
Is there any way to handle this without removing the data binding and manually setting the value (ie: some way to intercept it before the exception gets thrown and then setting the field value in the dataset)?
I'm using service broker and keep getting errors in the log even though everythig is working as expected
SQL Server 2005 Two databases Two end points - 1 in each database Two stored procedures: SP1 is activated when a message enters the sending queue. it insert a new row in a table SP2 is activated when a response is sent from the receiving queue. it cleans up the sending queue.
I have a table with an update trigger In that trigger, if the updted row meets a certain condition a dialogue is created and a message is sent to the sending queue. I know that SP1 and SP2 are behaving properly because i get the expected result. Sp1 is inserteding the expected data in the table SP2 is cleaning up the sending queue.
In the Sql Server log however i'm getting errors on both of the stored procs. error #1 The activated proc <SP 1 Name> running on queue Applications.dbo.ffreceiverQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
error #2 The activated proc <SP 2 Name> running on queue ADAPT_APP.dbo.ffsenderQueue output the following: 'The conversation handle is missing. Specify a conversation handle.'
I would appreceiate anybody's help into why i'm getting this. have i set up the stored procs in correctly?
i can provide code of the stored procs if that helps.
We have implemented our service broker architecture using conversation handle reuse per MS/Remus's recommendations. We have all of the sudden started receiving the conversation handle not found errors in the sql log every hour or so (which makes perfect sense considering the dialog timer is set for 1 hour). My question is...is this expected behavior when you have employed conversation recycling? Should you expect to see these messages pop up every hour, but the logic in the queuing proc says to retry after deleting from your conversation handle table so the messages is enqueued as expected?
Second question...i think i know why we were not receiving these errors before and wanted to confirm this theory as well. In the queuing proc I was not initializing the variable @Counter to 0 so when it came down to the retry logic it could not add 1 to null so was never entering that part of the code...I am guessing with this set up it would actually output the error to the application calling the queueing proc and NOT into the SQL error logs...is this a correct assumption?
I have attached an example of one of the queuing procs below:
Code Block DECLARE @conversationHandle UNIQUEIDENTIFIER, @err int, @counter int, @DialogTimeOut int, @Message nvarchar(max), @SendType int, @ConversationID uniqueidentifier select @Counter = 0 -- THIS PART VERY IMPORTANT LOL :) select @DialogTimeOut = Value from dbo.tConfiguration with (nolock) where keyvalue = 'ConversationEndpoints' and subvalue = 'DeleteAfterSec' WHILE (1=1) BEGIN -- Lookup the current SPIDs handle SELECT @conversationHandle = [handle] FROM tConversationSPID with (nolock) WHERE spid = @@SPID and messagetype = 'TestQueueMsg'; IF @conversationHandle IS NULL BEGIN BEGIN DIALOG CONVERSATION @conversationHandle FROM SERVICE [InitiatorQueue_SER] TO SERVICE 'ReceiveTestQueue_SER' ON CONTRACT [TestQueueMsg_CON] WITH ENCRYPTION = OFF; BEGIN CONVERSATION TIMER ( @conversationHandle ) TIMEOUT = @DialogTimeOut -- insert the conversation in the association table INSERT INTO tConversationSPID ([spid], MessageType,[handle]) VALUES (@@SPID, 'TestQueueMsg', @conversationHandle);
SEND ON CONVERSATION @conversationHandle MESSAGE TYPE [TestQueueMsg] (@Message)
END ELSE IF @conversationHandle IS NOT NULL BEGIN SEND ON CONVERSATION @conversationHandle MESSAGE TYPE [TestQueueMsg] (@Message) END SELECT @err = @@ERROR; -- if succeeded, exit the loop now IF (@err = 0) BREAK; SELECT @counter = @counter + 1; IF @counter > 10 BEGIN -- Refer to http://msdn2.microsoft.com/en-us/library/ms164086.aspx for severity levels EXEC spLogMessageQueue 20002, 8, 'Failed to SEND on a conversation for more than 10 times. Error %i.' BREAK; END -- We tried on the said conversation, but failed -- remove the record from the association table, then -- let the loop try again DELETE FROM tConversationSPID WHERE [spid] = @@SPID; SELECT @conversationHandle = NULL; END;
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go

@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,

In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.
SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.
I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help
I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:
m_sqlCmd.ExecuteScalar();
The m_sqlCmd has been fed an SQLParameter with direction set to output. When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok. When the row doesn't exist, in my watch I have:
m_sqlParam.SqlValue with value {Null}
I can't seem to work out how to test this value out. I've tried several things but none seem to work.
This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??
if (m_sqlParam.SqlValue != null).... {
// I'm here!! I thought the watch says this is null??? }
Sorry if this is obvious, but I can't work this one out!!
Looks like there was a fix and then I read this fix is not a fix. Does anyone know how this can be rectified? Does it mean that only Windows authentiation is the only way it works. The Software is over 2 years old, there are no excuses.

I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3)) RETURNS nvarchar(1000) WITH RETURNS NULL ON NULL INPUT AS EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
We have a case where in we should show date based on conditions for e.g if we had a column defined as
col varchar(10) then we would show col as 'NULL' for some condition and actual value when no condition
Normaly date values are stored here e.g under col 20150901 .
Case when col>'20150901' then 'NULL' else col end as Derivedcol
Note this is an extract process and we are presenting data by pumping the data in a table .
Now there is another similar column -colz varchar(10) which stores date but doesnt have case condition so whenever date has no value its shows null which is database null.
So whats the difference between database null and string null ?
How can we show database null for the case condition instead of string "null"?
Is it possible to catch and error and then keep the process going in a stored procedure? So if an update encounters a primary key violation on a row, is it possible to skip that row and keep the process going?
Hi! I have some try .. catch block trying to insert some data into database. During its action duplicate key row insert error could raise, for example. The question is how could I know distinguish it from other sql errors? Object ex (Catch ex As Exception) has only message property '{"Cannot insert duplicate key row in object 'dbo.Group_Courses' with unique index 'IX_Group_Courses'.The statement has been terminated."}' and type System.Data.SqlClient.SqlException. Knowing the type of error is not enough, because there are different SqlExceptions. Even the message is not unique for this error, because now i deal with 'dbo.Group_Courses' and then it could be other table. Is there something that unique identifies each error? For example error code. If it exists, where could I get it? Thanks in advance!
I test my the now function and it is getting the right date. When I try to send that to the sql database I have it turns it into 1/1/1900. Does anyone know why this is happening, I have tried everything Here is my code:
Hi, I would like to handle a sql error in t-sql and return a certain value in case error occurs. For example if I would like to add a record I want to return a certain identity value or maybe a status of transaction (0 for incomplete, 1 for succesfull trans). If error occurs in sql I cannot return any values back to asp.net because of What I am doing at the moment is catching an error in asp.net and then displaying an error message. Is there a way to return only a return value to asp.net and somehow handle the error in t-sql? Thanks
I don't know what's wrong with SQL2000 setup, the problem is: whenever I execute a query with a date/time such as 02/02/200, SQL give me an error message saying that the date is "Out of Range".
I'm having trouble with something and I was hoping that you could point me in the right direction.
Here's the scenario: I have a VB application that clients use to add records to a SQK 2K DB. The info they have added that day is shown in a grid. They have the ability to edit items in the grid, and then update those changes to the database. The problem is that sometimes they change the values to something they shouldn't. To combat this I've started experimenting with check constraints. In query analyzer I test the constraint by trying to update an entry to an 'illegal' value. When I do this, I get an error saying: "Server: Msg 547, Level 16, State 1, Line 1" and the change is not made. What I'd like to do is to give the user a dialog box notifying him of the error. Is there a way to have a sub-routine or stored procedure be triggered when a message of this type is generated?
My specs are: W2K pro clients, SQL2K on an NT4 sp6a server. Application is written in VB6.
I have a select statement that works, but I know there has to be a better way( I apologize for being TSQL brain dead today). Here is the statement
SELECT PATIENT_ACPT_STATUS, DISP_NOTES, RECORD_ID, modified_by, last_name, ddate FROM PATIENT_MEDICATION_DISPERSAL_ Where (ddate = convert(char(10),getdate(),101) and (MODIFIED_BY = CURRENT_USER) and rec_status = 1) or (ddate = convert(char(10),getdate(),101) and (PATIENT_ACPT_STATUS = 1)) OR (ddate = convert(char(10),getdate(),101) and (MODIFIED_BY = 'open'))
