DataSource Controls :: How To Select A Column With The Latest Datetime Data Type
Jun 14, 2010
How do I select a column with the latest "datetime" data type, in Visual Web Developer 2008, ASP.NET 3.5 ?
In the config data source WHERE option my options are greater than cookie, control, etc... but I would like to select where the datetime is the latest in the table.
How do I select a column with the latest "datetime" data type, in Visual Web Developer 2008, ASP.NET 3.5? In the config data source dialog my WHERE options are greater than cookie, control, etc... but I would like to select where the datetime is the latest in the table. (Select row from table where datetime is last updated....)
EDIT - This will be for a specific user in the table, i.e. Select row in table from specific current userid WHERE the row was his latest updated entry.
I have this error "The given value of type String from the data source cannot be converted to type datetime of the specified target column." when I used sqlbulkcopy to do the transaction
I'm trying to define a computed column that will contain an auto-incremented number. In other words, I want it to work exactly like identity, but since I can have only one identity column per table, I wanted to make a computed column that reads its latest value and increment it by 1.
I have an EntityDatasource that is bound to several TextBoxes used for querying (filtering) data in a ListView. The problem I am having is getting a DateTime to work. I just want to ignore the time portion of the variable and only look at the Date portion. Here is the markup I am using to generate the where clause. Does anyone know how to force it to just "drop" the time in the comparison?
I want to import a spreadsheet into SQL. The import/export wizard forces Column A to be a double. In Excel, the column is formatted as text. When I try to convert from double to text/varchar/nvarchar, the import process fails. Why can't I convert a number to text in SQL?
I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :
[Code]...
So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.
SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))
Running both statements above in the query analyzer it WILL return me different results. Why? Someone mentioned that it looks like I don't have correct data type specified for SQLParameter in .Net application. I was asked to create something like:
Am I going to be able to query (using LINQ to SQL) a database field with a type like the following "public System.Nullable<System.DateTime> Spouse_DOB"?
I'm trying to use the following code: [Code]....
and I get the error "'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)"
Is it because this DateTime column allows a NULL value (since everyone isn't married in my database)?
Error 1 'System.Nullable<System.DateTime>' does not contain a definition for 'Month' and no extension method 'Month' accepting a first argument of type 'System.Nullable<System.DateTime>' could be found (are you missing a using directive or an assembly reference?)

ObjectDataSource 'dsDiensten' could not find a non-generic method 'GetList' that has no parameters.
I need to display a single field from an sqlserver table, do I need to use sqlDataSource ect. or is there a simpler way (like msaccess's LookUp) for single values.
I have a gridview which has a column of auto generated select buttons, where a user can select a row.However, I would like to add a column header to my auto generated select buttons in order to make the gridview look complete, but I am unable to see how I can do this. Does anyone know how I can add a header text to an auto generated select button?
I read a CSV file into a DataTable.The DataTable in the first image shows each column and type.The types are exactly what they are supposed to be and the data loaded all the rows it was supposed to load.From the second screen shot you can see the database table. SqlBulkCopy is supposed to map column names to database columns by default.According to that logic each column matches up exactly to the database and the column types also match.However,when I run the command it errors on the first row with:
"The given value of type String from the data source cannot be converted to type decimal of the specified target column."
Here is the StackTrace:

Anyone have any ideas why this will not import correctly?

I am trying to create a multi column listbox by combining fields in Linq select statement, as Let Name = Last + First. The problem is how to pad the Last column with spaces as you would in SQL using REPLICATE so when I bind the listbox to the data, it looks like two columns.
