hi,
need script that transfer data from 1 table into another.
Old table :
CREATE TABLE [dbo]Master](
[Format] [varchar](11) NOT NULL,
[Class] [varchar](50) NULL,
[Product_Name] [varchar](100) NULL,
[Form_Code] [varchar](150) NULL,
[Strength] [varchar](50) NULL)
sample data :
Format Class Product_name Form_code Strength
0002-345 2 abc tab 300 MG
0056-345 null xyz sol 300 MG
4567-32 3 fgh tgb 56 MG
new table :
CREATE TABLE [dbo]child](
[Format] [varchar](11) NOT NULL,
[Class] [varchar](50) NULL,
[Product_Name] [varchar](100) NULL,
[Form_Code] [varchar](150) NULL,
[Strength] [varchar](50) NULL,
unit varchar(50))
sample data after inserting from old table :
Format Class Product_name Form_code Strength unit
0002-345 2 abc tab 300 MG
0056-345 null xyz sol 300 MG
now before transfering i need to see ,if format and classname are match with data in new table then just ignore,if not then insert row.
also in my old table i have strengh ,when i am inserting into new table , it shoudl be seperated in two field strenght and unit.
it is possible to write a script , that i can use in future also.for example, every time i need to change table name from script,when i am inserting from
old to new table.
any dynamic way

I suggest that you look at the MERGE statement (new in sql 2008) that said here is a good discussion with excellent examples that might be of use to you.

http://www.simple-talk.com/sql/learn-sql-server/the-merge-statement-in-sql-server-2008/

If everything seems to be going well, you have obviously overlooked something.

MERGE is overkill if all he wants to do is a conditional insert.

Are you talking about reusing this script for two tables using the same schema and the same transfer logic?

I'm pretty sure that you've been told previously how to get the best answers for things like this because I'm pretty sure I'm one of the folks that told you ;-). You got half of it by posting the table definitions. Now you need to post some readily consumable data that someone can write a coded example for you from.

Please read and heed the article at the first link in my signature lines below.
