Cannot Insert records in table using NHibernate

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
I am very much new with NHibernate. I am inserting a new record in the table. However, it seems that it does not insert. What I'm using is Fluent NHibernate.Below is the code which inserts records. public virtual void Save(string CreatedBy) { ISession NHSession = Star.CNPL_BusinessObjects.Common.Session.OpenSession(); ITransaction NHTransaction = NHSession.BeginTransaction(); try { this.Save(CreatedBy, NHSession); NHTransaction.Commit(); NHSession.Flush(); } catch (Exception ex) { NHTransaction.Rollback(); throw ex; } } public virtual void Save(string CreatedBy, ISession Session) { try { if (this.IsPersisted) { this.SaveAuditTrail(Session, false, CreatedBy); Session.SaveOrUpdateCopy(this); } else { Session.Save(this); } } catch (Exception ex) { throw ex; } }

SSIS : Insert, Update, Delete records from destination table by comparing records in source table.


Requirement: Inse

rt, Update, Delete records from destination table by comparing records in source table.

Update: if records exist in both the table compare them, and update value in destination table if value is different.

Insert: if record doesn't exist in destination table, add new record in destination table.

Delete: if record exist in destination table but not in source table, delete record from destination table.

----> I have created an SSIS package that does all this task but in order to perform delete operation, I have to store all records of destination table into a temporary table.
And since it's not the most efficient way, I have created another SSIS package by using Lookup & conditional Splits
method, now it works fine with inserting and updating information but I am not sure on how to handle removing record operation!

I would really appreciate if you could help me with this.

(In order to archive inserting and deleting records, I have referred following thread!

using SSIS How do I insert records from connection1 into a a table with the same name on connection2


How do I insert records from connection1 into a a table with the same name on connection2 where the records in connection2 do not already exist?

The approach I'm trying is this: I have an OLE DB Source that selects records from connection1 (successfully). The flow into a recordset destination in the Data Flow. But I can't figure out how to select from this recordset using the FROM CLAUSE of a SQL Command in the OLE DB Destination component. Can someone point me to an example of this?

It seems like this would be a common task but I can't find any examples.

I do not need to loop through the records. There is no need to evaluate each record. I simply need to do the SSIS equivilent of the following:

insert into tableA (col1) where not exists (select col1 from tableB where tableA.col1=tableB.col1)

The reason I cannot put this in a SQL Task is that tableA is on a different server than tableB, hence the two connections.

Need to add value to table on insert



I'm fairly new to .NET.  I need to add values CreatedBy, CreatedDate, ModifiedBy, ModifiedDate to the record before inserting it to the database. 

Please see code below. 

     [MetadataType (typeof(GRIPSMetaData))]
    public partial class SchoolDistrict
        internal void OnSaving(ChangeAction changeAction)
            if (changeAction == ChangeAction.Insert)
              this.CreatedBy = 5;
              this.CreatedDate = DateTime.Now;
            else if (changeAction == ChangeAction.Update)
                this.CreatedBy = 5;

insert new records in tables from dataset to database


I have 2 tables in SqlServer 2008.

Table1: T1id, SomeData

Table2: T2id, T1id, SomeData

I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns T1id in both tables.

Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.

I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

I think i'm getting it wrong with ForeignKeyConstraints, maybe UpdateRule is not set to cascade, i just don't know.

I have been trying to work this out for 6 days now and i'm about to break something on half.

Can someone please guide me to right direction, maybe post some sample, anything.... please!

How to setup db diagram to automatically insert username into table?

 I have a table setup in the database for users who are basically going to create a classified listing.  How can I setup a diagram that would easily create a table relationship with the Users table, so that it automatically inserts the users username when they submit a new ad?  If so, how?  I've tried adding a UserName row to my table and creating a relationship with the Users table "UserName" row, but it wasn't accepting the relationship when I tried to save the diagram...apparently because the UserName row in the Users table isn't a primary key?Also, one this is setup, what's the best way to provide the user a way to see a list of their ads and have the ability to edit them?

Inline Editing No Matching Records - No Insert

Hello.  I have been using Inline editing in Sharepoint Designer 2010.  Is it possible to have the insert link displayed even when there are no matching records?  The Default view shows edit, delete, and insert links.  But, the No-Matching Records template doesn't.  I think I can use Newform.aspx for the first record instead, but would like it to operate the same way for inserts as it does when there are records.  Thanks

Selecting different no. of records from the same table

Hello all, This might seem a basic thing but bothering me from last few days. Suppose I have a table containing 5 million records and I am running queries one by one (one query executes completly and then next query is fired)as below on that table. SELECT top 20000 FROM MyTable SELECT top 200000 FROM MyTable SELECT top 2000000 FROM MyTable  Now my questions are; Will SQL Server use same execution plan? As I am running these queries one by one in same order as given above, will second query take less time than it should if run standalone (only second query is fired, no query fired before that) and similarly will third query take less time than it should if run standalone (only third query is fired, no query fired before that), since there is a possibility of same execution plan being used?  Regards.    

Allow or deny roles to update, insert and delete records.

Hello, I have two roles "Admin" and "Basic". I also have a listview on the web page. My goal is that to make "Admin" role has the highest privilege to deal with records such as "insert", "update" and "delete". For the role "Basic", it only can update the records. Is there any sample code for that? Thanks.
