No records where inserted in my SQL Table after committing the transaction or after the .Flush() method. I checked the code and it follows the correct sequence of codes. I can't seem to find any other way where the error fails.
View 3 RepliesI am new to Nhibernate, I am trying to get record by ID and I am getting exceptionUnknown entity class: DAL.Producthere is my line of code where I am getting exception..

I am new to NHibernate and have just started right now.I have very simple table contain Id(Int primary key and auto incremented), Name(varchar(100)), Description(varchar(100))
Here is my XML
<class name="DevelopmentStep" table="DevelopmentSteps" lazy="true">
<id name="Id" type="Int32" column="Id">
</id> [code].....
Last night I started working on an NHibernate provider. I'm creating a criteria that several records will match, however I only want to return the most recent record (the record with the largest Id). I thought UniqueResult() would do this it cannot be used if a list would be returned otherwise.
I could theoretically select the full list and then return the desired record, but I believe there is a better way.
I am counting from a table for that i have written code as below
protected void get_Id_Afterpoint()
{
int counter = 0;
string strSql = "select count(*) as ID from tblEnergy where ID=?";
OdbcCommand com = new OdbcCommand(strSql, con);
com.Parameters.AddWithValue("ID", DropDownList1.SelectedValue);
OdbcDataAdapter oda = new OdbcDataAdapter(com);
DataTable dt = new DataTable();
oda.Fill(dt);
if (dt.Rows.Count == 0)
{
lblID2.Text = "1";
}
else
{
counter = dt.Rows.Count;
counter = counter + 1;
lblID2.Text = Convert.ToString(counter);
}
}
there is no record related to DropDownList1.SelectedValue. but as i am counting if(dt.rows.count) and i put break point on the bolded part it shows 1 record. how it can be possible?

Is it possible to use LINQ to delete a row in a table within an SQL database? I am using an ADO connected command statement to delete a row where a string column equals a name. But, I would prefer to use an easier way with LINQ, if possible.

Lets say I have a table of book reviews. Each book has a rating of 1 to 5. At the moment I am getting all book reviews by a bookID. I want to then say "Get the score that occurs most frequently for those given reviews". So if Book1 has reviews of 1, 1, 2, and 4, the statement would return 1. If Book1 has reviews of 1, 2, 2, 4, it would return 2.
I've been playing around with MVC lately, and was wondering how you could do this:
I have a view that displays a list of products, and against each product is a list of categories (in a combobox). I'm trying to find out how you can update a product's category when you select a category in the list. I know you could do something fairly simple with jQuery, but I'm trying to understand how submitting forms works with MVC.
Here's what I currently have:
[Code]....
But I'm not sure how to tell the controller what product needs to be updated when the form is submitted.
I want to insert a new record into a table. The table has relationships with other secondary tables, For example:
Table: Stores
Table StoreCategories (a store can have many of these)
I want to insert a new store, get its ID and insert some categories in one go.
How do I go about this?
I have 3 tables(Roles,Actions and RoleActionLinks). Roles table has few columns(RoleID,RoleName,Desc). Actions table has few colums(ActionID,ActionName,Desc). In RoleActionLink is created for store the association between Roles and Actions and this table has the columns such as RoleID,ActionID When I created the data model(edmx). it shows only Role and Action as entity. i did not find RoleActionLink table. but even there is no direct relation between Roles and Actions table, both tables are automatically related using RoleActionLink table. When i create the new Action, a action record should be populated in Action table(this is works fine). At the same time, i need to populate record in RoleActionLinks table. But i dont have the entity to populate.

Does that make sense?
