im new in postgresql (actually came from SQL Server) and i was trying a
script like this

insert into table1(field1,field2) values (select field1, field2 from table
2);

i dont know if this is possible (inserting a set of entries via resultset
from a select stmt in one command).  If anyone has any answers, or
workarounds pls do email me

Thanks

Well, that syntax doesn't work on SQL Server either.

I think what you want is:   insert into table1(field1,field2) select field1, field2 from table2;

The correct syntax is:

INSERT INTO table1 (field1, field2) SELECT field1, field2 FROM table2;

Try:
Create table table1(field1,field2) as (select field1, field2 from table2);

You can, but you don't need to use values.

insert into table1(field1, field2) select field1, field2 from table2;
should do what you want.

Actually, that won't work in SQL Server either.  The correct syntax (for
both databases) is:

INSERT INTO table1 ( field1, field2 )
SELECT field1, field2 FROM table2;

The "VALUES" syntax is only appropriate if you are inserting a set of
constants with no SELECT statement involved.
