Hi,
I have an old_table with two columns: "id" and "old_attribute". I have
new table with the columns "id" and "new_attribute".
old_table and new_table contain exactly the same id's. Now I want to
copy all the old_attribute from old_table to the corresponding
new_attribute in the new_table
Why?. You can simply rename the old_table to new_table including column names (if any).
Is that possible in a SQL script (pgadmin or psql console?) and if so,
what is the syntax in this example?
I have tried something as:
insert into new_table(new_attribute)
value( select old_attribute from old_table, new_table where old_table.id
= new_table_id)
where new_table.id = old_table.id
You need an update statement and not an insert statement.
TIA
