Here is a stored procedure that dumps the results of an arbitrary query (eg: select * from T) to a file using utl_file:
create or replace function dump_csv( p_query in varchar2, p_separator in varchar2 default ',', p_dir in varchar2 , p_filename in varchar2 )return number
l_output utl_file.file_type; l_theCursor integer default dbms_sql.open_cursor; l_columnValue varchar2(2000); l_status integer; l_colCnt number default 0; l_separator varchar2(10) default ''; l_cnt number default 0;
l_output := utl_file.fopen( p_dir, p_filename, 'w' );
dbms_sql.parse( l_theCursor, p_query, dbms_sql.native );
for i in 1 .. 255 loop
begin dbms_sql.define_column( l_theCursor, i, l_columnValue, 2000 ); l_colCnt := i; exception when others then if ( sqlcode = -1007 ) then exit; else raise; end if; end;
dbms_sql.define_column( l_theCursor, 1, l_columnValue, 2000 );
l_status := dbms_sql.execute(l_theCursor);
loop
exit when ( dbms_sql.fetch_rows(l_theCursor) <= 0 ); l_separator := ''; for i in 1 .. l_colCnt loop dbms_sql.column_value( l_theCursor, i, l_columnValue ); utl_file.put( l_output, l_separator || l_columnValue ); l_separator := p_separator; end loop; utl_file.new_line( l_output ); l_cnt := l_cnt+1;
utl_file.fclose( l_output );
return l_cnt;
end dump_csv;
/
You can schedule that as a job using dbms_job. Or if you prefer to use cron under unix to schedule, see the url in my signature for sqlplus scripts that do the same sort of thing (arbitrary table -- dump to flat file or sqlldr format)
