Can we export DATA from all tables in a schema?

Question

Hi,
I have a question; Can we export all the DATA from all the tables present in the schema to any source (eigther CSV, TXT, DAt, etc..)?
Or
Can I have a PL/SQL procedure to display DATA from all Tables in a schema?
With Best Regards,

Hi,
This is pretty much what you need.
DECLARE
V_COUNT NUMBER;
v_sql varchar2(1000);
IN_OWNER_NAME VARCHAR2(100) := 'AP' ; -- SCHEMA NAME
TYPE T_COL_NAME is table of varchar2(1000) index by binary_integer;
v_col_tbl t_col_name;
BEGIN
FOR i in
(SELECT object_name
FROM dba_objects
     WHERE owner = IN_OWNER_NAME
     AND object_type ='TABLE'
and rownum < 2)
LOOP
v_sql := 'SELECT COUNT(*) FROM ' || i.object_name ;
EXECUTE IMMEDIATE v_sql INTO V_COUNT;
if v_count > 0 then
v_sql := 'SELECT * FROM ' || i.object_name ;
select column_name
bulk collect
into v_col_tbl
from DBA_TAB_COLUMNS
WHERE TABLE_NAME = I.OBJECT_NAME
AND OWNER = IN_OWNER_NAME;
-- start selecting the column and exporting using the column names selected.     
end if;
if v_col_tbl.count > 0 then
for i in v_col_tbl.first .. v_col_tbl.last
loop
DBMS_OUTPUT.PUT_lINE(v_col_tbl(i));
end loop;
end if;
DBMS_OUTPUT.PUT_lINE( i.object_name || '-' || v_count);
END LOOP;
END;
