Question

I want to insert values into a table_A from table_B where some conditions are met. Here is what I want to do but does not work:

insert into table_A(ID, value1, value2)
select ID, value1, value2
from table_B
where table_B.ID <> table_A.ID

I am getting this error:

The multi-part identifier “table_A.ID” could not be bound

thanks

It does not work like that. You are not joining the tables in an insert statement. Use

insert into table_A(ID, value1, value2)
select ID, value1, value2
from table_B
where ID not in (select ID from table_A)
