How to copy all tables, triggers, etc from one user schema to another

Question

Hello everybody!
I am searching for a QUERY or Stored Procedure to copy the tables of one user schema to another schema.
Should look kind of: Copy (Select * from all_objects where owner = 'UserIwantToCopyFrom') to user = 'UserIwantToCopyTO'
I am sure that my example is rubbish but I tried to explain what I want to do.
So is there a chance to do that within sql-code? I have to build a template of a user schema with hundreds of tables, triggers, etc and copy it to several other user schemas.
Thanks for your advice!

There are numerous examples available.
What you typically will want to do is:
For the export use the job_mode => 'SCHEMA' option
Export example
http://www.oracle-base.com/articles/10g/OracleDataPump10g.php
DECLARE
  l_dp_handle       NUMBER;
  l_last_job_state  VARCHAR2(30) := 'UNDEFINED';
  l_job_state       VARCHAR2(30) := 'UNDEFINED';
  l_sts             KU$_STATUS;
BEGIN
  l_dp_handle := DBMS_DATAPUMP.open(
    operation   => 'EXPORT',
    job_mode    => 'SCHEMA',
    remote_link => NULL,
    job_name    => 'EMP_EXPORT',
    version     => 'LATEST');
  DBMS_DATAPUMP.add_file(
    handle    => l_dp_handle,
    filename  => 'SCOTT.dmp',
    directory => 'TEST_DIR');
  DBMS_DATAPUMP.add_file(
    handle    => l_dp_handle,
    filename  => 'SCOTT.log',
    directory => 'TEST_DIR',
    filetype  => DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE);
  DBMS_DATAPUMP.metadata_filter(
    handle => l_dp_handle,
    name   => 'SCHEMA_EXPR',
    value  => '= ''SCOTT''');
  DBMS_DATAPUMP.start_job(l_dp_handle);
  DBMS_DATAPUMP.detach(l_dp_handle);
END;
/for the import you will have to use the remap_schema option with:
DBMS_DATAPUMP.METADATA_REMAP (
   handle      IN NUMBER,
   name        IN VARCHAR2,
   old_value   IN VARCHAR2,
   value       IN VARCHAR2,
   object_type IN VARCHAR2 DEFAULT NULL);There are much more details in the document that Thierry provided.
