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?
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!?
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)?
Hi , I need to compare two date fields in two different tables.One of the field is varchar(8) and other is dateime.When there is a date in one field and NULL in other field , how do I compare these two vales?
I would like some suggestions on how to keep from displaying the value "1/1/1900" on my asp pages when my recordset field returns a Sql date value that is null
How do I order a query by a date field ASC, but have any NULL valuesshow up last? i.e.7/1/20037/5/20037/10/2003<NULL><NULL>Any help will greatly be appreciated
I am attempting to create search parameters for a gridview control and I am experiencing a small issue. When I get to a date parameter I am unable to display null values. I setup a sqldatasource and created the parameters below to handle the selections for minimum date required and the maximum date required for the date columns in the database. The problem is I do not know how to display null dates. Is there a way to incorporate something into the search page to show null dataes?

I am using a DAL and i want to insert a new row where one of the columns is DATE and it can be 'NULL'. I am assigning SqlTypes.SqlDateTime.Null. But when the date is saved in the database, i get the minvalue (1/01/1900) . Is there a way to put the NULL value in the database using DAL????how can i put an empty date in the database? THANK YOU!!!
We are just upgrading a server from 2000 to 2005 and we are getting the message below when we execute a sql statement against a table with a date field with null values:
"Error converting data type DBTYPE_DBTIMESTAMP to datetime."
I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?
I already asked this question; however, I am giving all the detailsnow:We get large files(millions of records) and we need to load it into ourtables using import export wizard. Some of the fields in the file canbe Null and so we are forced to create table with fields that allowNulls with default ''. However when we insert data into these tablesit puts Null in those fields even though we have a default '' (I do notthink we have any work around for that; do we?)Finally we need to go through each field and update it to '' if it is aNull and that takes LOT OF TIME.If (select count (*) from <tablename> where <columname> is Null) >0BeginUpdate <tablename>set <columnName> = ''where <columnName> is NullendPlease 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?
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.
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.
hi, I am getting a data in a dbf file and they have a StartDate and end Date for where the Statments are valid for.. How can i incorporate them into the database.. right now We are doing with PeriodId.. like while the user imports the data they select which period they want to import the data into.. But now if i have to get those details from the Database how do i store it in the Database..and i need to store them in multiple tables.. Thanks Karen
Q1. Model Prediction -- Suppose we already have a trained Microsoft Linear Regression Mining Model, say, target y regressed on two variables:
x1 and x2, where y, x1, x2 are of datatype Float. We try to perform Model Prediction with an Input Table in which some records consist of NULL x2 values. How are the resulting predicted y values calculated?
My guess:
The resulting linear regression formula is in the form:
where avg_x1 is the average of x1 in the training set, and avg_x2 is the average of x2 in the training set (Correct?).
I guess that for some variable being NULL in the Input Table, Microsoft Linear Regression just treat it as the average of that variable in the training set.
So for x2 being NULL, the whole term coeff2 * (x2 - avg_x2) just disappear, as it is zero if we substitute x2 with its average value.
Is this correct?
Q2. Model Training -- Using the above example that y regressed on x1 and x2, if we have a train set that, say, consist of 100 records in which
y: no NULL value
x1: no NULL value
x2: 70 records out of 100 records are NULL
Can someone help explain the mathematical procedure or algorithm that produce coeff1 and coeff2?
In particular, how is the information in the "partial records" used in the regression to contribute to coeff1 and the constant, etc ?

I have a DTSX package which reads values from a fixed-length text file using a data reader and writes some of the column values from the file to an Oracle table. We have used this DTSX several times without incident but recently the process started inserting NULL values for some of the columns when there was a valid value in the source file. If we extract some of the rows from the source file into a smaller file (i.e 10 rows which incorrectly returned NULLs) and run them through the same package they write the correct values to the table, but running the complete file again results in the NULL values error. As well, if we rerun the same file multiple times the incidence of NULL values varies slightly and does not always seem to impact the same rows. I tried outputting data to a log file to see if I can determine what happens and no error messages are returned but it seems to be the case that the NULL values occur after pulling in the data via a Data Reader. Has anyone seen anything like this before or does anyone have a suggestion on how to try and get some additional debugging information around this error?
how to handle space between multi-value parameter values in SSRS. For e.g. if the values are as follows -'KLO LUG', 'HGY KIU', 'LOT JUY', I know I can use the split function for the commas but its the space between the value which is the problem.
We have a table in our legacy database system representing health insurance polices. The customer can, and usually does, renew the policy after 12 months. The legacy database uses the renewal string "99/99/9999" to signify "continuous until cancelled", in other words, "forever", or until cancelled
We need to convert this legacy table into a sql 2005 table, which supports the concept of "forever". But how can we do this? ("99/99/999" is not a valid sql date type and we don't want to use varchar for dates.)
I have SQL Server 2012 SSIS. I have Excel source and OLE DB Destination.I have problem with importing CustomerSales column.CustomerSales values like 1000.00,2000.10,3000.30,NotAvailable.So I have decimal values and nvarchar mixed in on Excel column. This is requirement for solution.However SSIS reads only numeric values correctly and nvarchar values are set as Null. Why?
can somebody explain me how I can assign a NULL value to a datetime type field in the script transformation editor in a data flow task. In the script hereunder, Row.Datum1_IsNull is true, but still Row.OutputDatum1 will be assigned a value '0001-01-01' which generates an error (not a valid datetime). All alternatives known to me (CDate("") or Convert.ToDateTime("") or Convert.ToDateTime(System.DBNull.Value)) were not successful. Leaving out the ELSE clause generates following error: Error: Year, Month, and Day parameters describe an un-representable DateTime.
My query "select blah, blah, rank from tablewithscores" will return results that can legitimately hold nulls in the rank column. I want to order on the rank column, but those nulls should appear at the bottom of the list
I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.
What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column.
I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.
I have a QA Deployment Date field that is being returned in a custom report I created. I also found a sample date range parameter:
What I want to accomplish:
I want to select a From and To Date and filter the report to only display the rows that have the QA Deployment Date within the selected range.
For example.. I want to select From Date (8/1/2105) and To Date (8/31/2015) and I only want to return only the results that have a QA Deployment date between that selected range.
Hi, I ve a table, I want to fetch certain rows based on the value of a Column. That column is nullable, and contains NULL values.I used the following query,SELECT Col_A FROM TABLE1 WHERE SOME_ID = 1317 AND Col_B NOT IN (8,9) Here, Col_B contains NULL values too. I need to fetch all rows where Col_B is not 8 or 9.Now, if I use "NOT IN", it does not work. I tried reading on it and got to know why it does not work. Even "NOT EXISTS" does not help. But still I've to fetch my values. How do I do that?Thanks & Regards,Jahanzeb
I have tried doing a search, as I figured this would be a common problem, but I wasn't able to find anything. I know that my SP is functional because when I use VWD execute the query outside of the webpage, I get the correct results -however I have to ensure that a field is either entered, or set to <NULL>. In my SET's I want it to use the wildcards. What I want is to do a search (plenty of existing topics on that, however none were of help to me). If a field is entered, then it is included in the search. Otherwise it should be ignored. In my VB I have the standard stored procedure call, passing in values to all of the parameters in the stored proc below: CREATE PROCEDURE dbo.SearchDog@tagnum int,@ownername varchar(50), @mailaddress varchar(50),@address2 varchar(50),@city varchar(50),@telephone varchar(50),@doggender varchar(50),@dogbreed varchar(50),@dogage varchar(50),@dogcolour varchar(50),@dogname varchar(50),@applicationdate varchar(50)AS IF @tagnum=-1 SET @tagnum=NULL SET @ownername = '%'+@ownername+'%' SET @mailaddress = '%'+@mailaddress+'%' SET @address2='%'+@address2+'%' SET @city = '%'+@city+'%' SET @telephone='%'+@telephone+'%' SET @dogcolour='%'+@dogcolour+'%' SET @dogbreed='%'+@dogbreed+'%' SET @dogage='%'+@dogage+'%' SET @doggender='%'+@doggender+'%' SET @dogname='%'+@dogname+'%' SET @applicationdate='%'+@applicationdate+'%' SELECT DISTINCT * FROM DogRegistry WHERE ( TagNum = @tagnum OR OwnerName LIKE @ownername OR MailAddress LIKE @mailaddress OR Address2 LIKE @address2 OR City LIKE @city OR Telephone LIKE @telephone OR DogGender LIKE @doggender OR DogBreed LIKE @dogbreed OR DogAge LIKE @dogage OR DogColour LIKE @dogcolour OR DogName LIKE @dogname OR ApplicationDate LIKE @applicationdate ) AND TagNum > 0GO I don't know why it is creating links inside my SP -ignore them. TagNum is the primary key, if that makes a difference. On the webpage, it ONLY works when every field has been filled (and then it will only return 1 row, as it should, given the data entered). Debugging has shown that when nothing is entered it passes "". Any ideas?
