Обсуждение: running scripts like oracle sqlplus

I have been trying to figure out how I can run a pgsql script like I can run a plsql script with oracle's sqlplus. 
Hereis a sample script file for what I want to run:<br /><br />declare<br />  sysuserid integer := 0;<br />  hwcustid 
integer:= 0;<br /> begin<br /><br />select nextval( 'user_seq' ) into  sysuserid;<br />select nextval( 'customer_seq'
) into hwcustid;<br /><br />insert into user<br />(<br />  user_id,<br />  customer_id,<br />  create_user,<br /> 
update_user<br/> )<br />values<br />(<br />  sysuserid,<br />  hwcustid,<br />  sysuserid,<br />  sysuserid<br />);<br
/><br/>insert into customer<br />(<br />  customer_id,<br />  create_user,<br />  update_user<br />)<br />values<br
/>(<br/>  hwcustid,<br />  sysuserid,<br />   sysuserid<br />);<br /><br />commit;  <br /><br />end;<br /><br />I try
torun the script in psql and thru pgadmin and cannot seem to make them work.  I do not want to turn it into a
function. I just want it to execute the block in a fashion similar to Oracle'sqlplus running @scriptfile.sql.<br /><br
/>Thanks<br/>

I think you will need to wait for version 9.0 and anonymous functions
using DO.

Have you tried nextval & currval?
http://www.postgresql.org/docs/8.4/interactive/functions-sequence.html 

Something like this:


begin

insert into user
(
  user_id,
  customer_id,
  create_user,
  update_user
)
values
(
  nextval(user_seq),
  nextval(customer_seq),
  currval(user_seq),
  currval(user_seq)
);

insert into customer
(
  customer_id,
  create_user,
  update_user
)
values
(
  currval(customer_seq),
  currval(user_seq),
  currval(user_seq)
);

commit; 

end;
