Hi,
You can load the requested list of tables onto a temporary table using sqlloader and pass as in put to the your procedure.
Assume that you have loaded the table names onto the table aksi_tmp;
Sample procedure
CREATE OR REPLACE PROCEDURE aksi_prc(tbl_name IN VARCHAR2)
IS
sql_stmt1 varchar2(200):='ALTER TABLE';
sql_stmt2 varchar2(200):='RENAME TO';
prefix varchar2(10):='BKUP';
sqlstmt_final varchar2(200);
invalid_table EXCEPTION;
pragma exception_init(-00942,Invalid_table);
BEGIN
sqlstmt_final:=sql_stmt||' '||tbl_name|| ' '||sq_stmt2|| ' '||prefix||'_'||tbl_name;
--FOR table t2 abv statement will return ALTER TABLE t2 RENAME TO BKUP_t2;
EXECUTE IMMEIDATE sqlstmt_final;
EXCEPTION when invalid_table then
null;
END;
DECLARE
CURSOR c1 IS
SELECT col1
from t2;
BEGIN
for i in c1
LOOP
aksi_prc(i.col1);
END LOOP;
END;Hope this helps..
