postgresql: INSERT INTO … (SELECT * …)

Question

I\'m not sure if its standard SQL:

 INSERT INTO tblA 
 (SELECT id, time 
    FROM tblB 
   WHERE time > 1000)  

What I\'m looking for

Answer 1

Here's an alternate solution, without using dblink.

Suppose B represents the source database and A represents the target database: Then,

1. Copy table from source DB to target DB:

   pg_dump -t   | psql 
   

2. Open psql prompt, connect to target_db, and use a simple insert:

   psql
   # \c ;
   # INSERT INTO (id, x, y) SELECT id, x, y FROM ;
   

3. At the end, delete the copy of source_table that you created in target_table.

   # DROP TABLE ;
