Hi,
I have to load data into Oracle tables. The data file consists of '#' as a column delimiter and '^' as row delimiter.
Could any one help me how to write a control file with record delimiter.
Could any explain the difference between conventional and direct method and also the clause ' OPTIONALLY ENCLOSED BY '"'.
Any help really appreciated.
Thanks in advance.

You can use utl_raw.cast_to_raw to get the hexidecimal representation of your record delimiter, then you can use that in your control file.
Optionally enclosed by means that the field may or may not begin and end with whatever the enclosure symbol is, but that if it is enclosed then that symbol should not be counted as part of the data and any delimiters within those enclosures should be considered part of the data, not delimiters.
You can read about the conventional and direct path loading methods in the following section of the online documentation:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/ldr_modes.htm#i1007501
The example below demonstrates usage of a feld terminator of # with an optional enclosure character of
~ and a record delimiter of ^.
SCOTT@orcl_11g> select utl_raw.cast_to_raw ('^') as "hexidecimal for ^" from dual
2 /
hexidecimal for ^
--------------------------------------------------------------------------------
5E
SCOTT@orcl_11g>
-- test.dat:
1#2#3#4#^5#6#~7~#8#^9#10#11#12#^13#14#15#16#^
-- test.ctl:
load data
infile test.dat "str X'5E'"
into table test_tab
fields terminated by '#' optionally enclosed by '~'
(col1, col2, col3, col4)
-- test table:
SCOTT@orcl_11g> create table test_tab
2 (col1 number,
3 col2 number,
4 col3 number,
5 col4 number)
6 /
Table created.
-- load:
SCOTT@orcl_11g> host sqlldr scott/tiger control=test.ctl log=test.log
-- results:
SCOTT@orcl_11g> select * from test_tab
2 /
COL1 COL2 COL3 COL4
---------- ---------- ---------- ----------
1 2 3 4

You have a space between X and '5E' that does not belong there. If you remove the space, 8 rows are loaded. 4 rows are not loaded because the comment data is too long. You could also use:
"str '^'"
instead of
"str X'5E'"
since the ^ is a visible character.
