David,

About the only thing that I can think of is to create a function that does this:

CREATE OR REPLACE FUNCTION tom_get_val
RETURN NUMBER IS ret_val NUMBER;

BEGIN BEGIN
  SELECT tom_seq.CURRVAL INTO ret_val FROM dual;     EXCEPTION

	  WHEN OTHERS THEN
	     SELECT tom_seq.NEXTVAL INTO ret_val FROM dual;
END;
		 RETURN ret_val;

END; And then in your sqlldr file:

(BATCHID

     EXPRESSION 
          "tom_get_val"

Havn't tried this, but I have used functions withing sqlldr before.

Good Luck.

Subject: RE: sql loader problem

(Sorry, sent this out under the wrong header)

Now that data loads, I can't figure out how to do one thing.

Two batch identification columns,

batchid
batchrecnum

batchid should have the same value for each record loaded in the same sqlldr run. batchrecnum should start at 1 for each sqlldr run, and increment by 1.

So, here's the relevant portion of the control file:

(BATCHID

     EXPRESSION 
          "NVL(BATCHID_SEQ.CURRVAL,BATCHID_SEQ.NEXTVAL)"

,BATCHRECNUM
    RECNUM batchrecnum works like a charm.

I didn't actually expect a reference to the sequence currval to work like this (before a reference to nextval first), but it didn't raise an error.
(I just hoped to illustrate clearly what I wanted.) However, the data
loaded! But, it gives me the next value from the sequence for each new record.

So, instead of getting, in one load (where the next value of batchid_seq would be
5:

5,1
5,2
5,3
5,4

I'm getting,

5,1
6,2
7,3
8,4

Any ideas, besides hard-coding the batchid value for the run into the sqlldr control file? I don't want to do that...
