Extract a subset of columns

The schema command file in this example extracts a table test1:tlr from the most recent backup of dbspace1 and places a subset of the data into the table test1:new_dest
database test1;
create table tlr    (
   a_serial   serial,
   b_integer  integer,
   c_char     char(20),
   d_decimal  decimal
   ) in dbspace1;
create table new_dest (
   X_char     char(20),
   Y_decimal  decimal,
   Z_name     char(40)
   ) in dbspace2;
insert into new_dest (X_char, Y_decimal) select c_char,d_decimal from tlr;
