Access :: Return The Column Name For Row With Last Non-null Value?

May 28, 2010

I have a Table, which contains a list of league players. Each season, we record their Points per Dart. Their total PPD for that season is stored in other tables and extracted through other queries, which in turn are imported to the master table "Player History" at the end of the season for use as historical data.

The current query retrieves each players PPD for each season they played, when they played last, and how many seasons played.

The code for Last season Played has become too long and unstable to use. it was originally created, and split into two separate columns because a single SQL was to long. (LSP1) and LSP2) which work, but as I add seasons, Access does not like the length of code.

In short, i need to find a more simple code that will look at each row, and look in that row for the last non null cell and report which column that last non null value is in.

So if a player played seasons 30 & 31, but did not play 32..but did play 33, the Column with the code should be titled Last Season Played, and for that Player, it would state "33" in that cell, indicating that this player last played season "33"

I'm using a custom ashx HttpHandler to retrieve gif images from a database and show it on a website - when the image exists, it works great.

However, there are cases when the image will not exist, and I'd like to have the html table holding the image to become invisible so the "image not found" icon is not shown.

Access :: Insert Records Into Access (not Inserting Null Values)?

Nov 12, 2010

I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.

So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...

OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();

It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.

Update Nullable Column In Db To Null?

Sep 13, 2010

Can anyone reliably get the EDS to save a nullable column to the databse as a "null" when bound to any of the controls such as "FormView"?I have tried using several different UpdateParameters (Session, ControlParamater, Parameter, etc). I have tried setting "ConvertEmptyStringToNull" to true and leaving the property off entirely. Nothing works. On my "Inserts" it works fine.(I have made sure the column is set to nullable = true in the Entity Designer.....)

Databases :: MySqlException: Column Cannot Be Null?

Jan 11, 2010

I'm writing a function in "Query Browser" to add some values to a table.

The function should get this value when the stored procedure is called upon, thus te code looks like:

INSERT INTO customer(customer_name, customer_city) VALUES (@customer_name, @customer_city);

But when trying to execute the function, it says "customer_name can't be null"

i thought maybe it just waiting for the values to be sent from .aspx page, but yet again, i get the same error message.
