  SCENARIO,

  i have tbl1, tbl2,tbl3 in qa and prod.

  tbl1(id int identity(1,1),DomainName varchar(250),Daate datetime,results varchar(20))

  tbl2(id int identity(1,1),tbl1_id int,Desc varchar(max))

  tbl3(id int identity(1,1) ,tbl2_id int,comment varchar(max))

  At this point i assume we all understand the relationships between these 3 tables,

  tbl1 -<tbl2 ->tbl3

  I need to import data from QA to Prod where the date is between startdate and endDate.

  Can somebody help me with a script that can do this while carrying over the id value from tbl1 to be inserted to tbl2 field called tbl1_id and

  then inserting the required data from tbl2 QA to tbl2 PROD.

  however as the insertion to tbl2 happens the tbl2 id needs to be carried to tbl3 as a foreign key.

  how can i write this while loop or something?

  Making assumptions is a bad thing around here. can you also post some sample data and the foreign keys between the tables? with out sample data its hard to work with things. since you said QA and Production im guessing the tables are the same in each??

  Here are the tables in a nice and readily consumable format. for the sample data please see the link in my signature for the best way to post the sample data.

  CREATE TABLE tbl1(

  id int identity(1,1),

  DomainName varchar(250),

  [Date] datetime,

  results varchar(20)

  )

  CREATE TABLE tbl2(

  id int identity(1,1),

  tbl1_id int,

  [Description] varchar(max)

  )

  CREATE TABLE tbl3(

  id int identity(1,1),

  tbl2_id int,

  comment varchar(max)

  )

  No. There is no “carry” operator in SQL or RDBMS.

  Actually, there is. It's called OUTPUT. 😉

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
