Help with transaction; Related tables

I am creating a transaction.   I have done this before with unrelated tables.   However, now I have related table.  Say I have an "organization" table.   Then I also have a "member" table, which has a foreign key to the "organization" table.   If I add a new organization, I need the primary key of that record to then use on the INSERT for the "member" table.   If this was not within a transaction, I would use SELECT Scope_Identity() and .ExecuteScalar to obtain the Primary Key.  

How do I do this same thing within a transaction?

Yes. You can use it in a transaction. Why do you mention .ExecutScalar? Consider using a single T-SQL batch or even better a stored procedure to do this.

I mention .ExecuteScalar because that's how I got back the Primary key; that the only way I know how get it.  

So, are you saying I can use SELECT Scope_Identity()  in a transaction?  How exactly?

E.g.

INSERT INTO tableName () VALUES ();

DECLARE @ID INT = SCOPE_IDENTITY();

INSERT INTO otherTableName () VALUES ( @ID.. );

@I would use SELECT Scope_Identity()

Is primary key a Identity column in Organization table ?

if yes then you can take the advantage of Scop_identity() if not then you can use output clause in T-SQl script.

I got it working.  Thanks
