Hello Friends,
I have a business requirement to create an SSIS package that is triggered whenever a new record is added to the table in the database.
What the SSIS package should do is to append the new record to the records in the equivalent table.
Thanks and Regards,
Paul

Where is this 'equivalent table'?

Isn't it much much easier to use a trigger on the table that will write the rows to the "equivalent table" using the INSERTED table?

What is the insert volume of the table, as you really dont want to be initiating an SSIS package on every Insert if theres a high volumne of Inserts, as you would get a lot of overlap.

I would suggest using a trigger IF the databases are on the same server.

If they're on different servers then you might be better setting seperate table that just contains ID's of the rows added since the last batch, and a moved flag.

Using an Insert Trigger to keep this updated with new row id's, then have an SQL Agent job that polls this table every so often (10-15 minutes), which then pushes the new records through to the destination table.

Its a very crude but effective version of CDC, dont forget that once you have Loaded batch of records you simply update the flag on the trigger table to say they are loaded, not forgetting to clear it down once a day.

Hi Phil,

Thanks for your reply.

The equivalent tables are on a different server. So basically, the scenario is that when the records are added to the tables in the database on server 1 , then the SSIS package on server 1 should append the same records to the existing records in database on server 2.

Thanks,

Paul

In that case, wouldn't it be easier to implement replication, mirroring or log shipping instead of re-inventing the wheel?

In my opinion, log shipping is the easiest method.

Hello Koen,

Thanks for your replies. Actually I am quite new to SSIS and am having a little difficulty understanding your solution. Would it be possible to explain what do you mean by log shippng ?

Thanks and Regards,

Paul

Log shipping (it has nothing to do with SSIS):

This is more work for a DBA then for a developer (as are the other solutions I mentioned).

Hi Again,

So is Log shipping the only solution to this or can I make use of another solution as a developer. I don't know where I am going with this.

Thanks,

Paul

Did you take a look at Jason's suggestion? It might work for you.

Did you take a look at Jason's suggestion? It might work for you.

I studied Jason's solution but it doesnt seem to be according to the business requirement in terms of updating the flag and then clearing it down once a day. The process needs to be automated and should not include anything which should be done manually everytime. Is there some other different way by just using SSIS ? I am really stuck on this one now.

Thanks and regards,

Paul

I do not agree with your assessment - try re-reading it. Once it is set up, a SQL Agent job takes care of everything without manual input.

Okay Phil, I have read the solution again. Could you please explain what is meant by :

1. Setting separate table that contains ID's- Does he mean primary key column by this ?

2. Moved flag ?

3. Insert trigger

I am quite new to Sql server and facing difficulty understanding this. Would it also be possible for you to construct a sample query based on what Jason mentioned ?

Thanks,

Paul

Sorry Paul, I do not have time to provide a detailed answer. But, in short:

1) Yes

2) A Boolean field, Yes if data already moved to new table, No/Null otherwise.

3) You should read up on this. A trigger is a procedure defined against a table which will fire when an event occurs. These events can be inserts, updates, deletes and others (a different trigger can be defined for each event). So, in this case, the trigger can detect that new data has been inserted to the table and react by inserting the newly created primary keys into your new tracking table.

Hi Jason,

I hope you are doing fine. Would it be possible for you to create a sample query based on what you have mentioned in your solution ? I think it can be achieved using your suggestion but I am not sure how to make a start with this.

Thanks and Regards,

Paul
