Create sequence numbers when importing data

Question

Hi I am looking at inserting some data into a table that already has data in.
I have a 2 sequence numbers that I need to include in the statement. The First (RSC_RDSS) needs to be pulled from another table SRS_RDS field RDS_SEQ2 where the RDS_SCJC is the same on both records. The second RSC_SEQN needs to increment by 1 from any existing records.
I currently have a basic script:
INSERT INTO SRS_RSC (RSC_SCJC, RSC_FTIT, RSC_RDSS, RSC_SEQN, RSC_BEGD, RSC_ENDD, RSC_NOTE)
VALUES ('0848633/2','ELC100/10: Academic Grammar','1','50',to_date('04-Apr-11'),to_date('04-Apr-11'),'Test heading');
How can I get the RSC_RDSS from another table and how can I get the RSC_RDSS to look at what is in the table in terms of how many records for that person (RSC_SCJC) and increment by one?
Many thanks in advance.

Answer 1

Sorry one more question my script is now below and will work for the one record specified '0848633/2':
INSERT INTO SRS_RSC (RSC_SCJC, RSC_FTIT, RSC_RDSS, RSC_SEQN, RSC_BEGD, RSC_ENDD, RSC_NOTE)
select
'0848633/2' as RSC_SCJC,
'ELC100/10: Academic Grammar' AS RSC_FTIT,
(select max(RSC_RDSS) from SRS_RSC where RSC_SCJC ='0848633/2') as RSC_RDSS,
(select max(RSC_SEQN)+1 as RSC_SEQN from SRS_RSC) as RSC_SEQN,
to_date('04-Apr-11') RSC_BEGD,
to_date('04-Apr-11') RSC_ENDD,
'Test heading' RSC_NOTE
from dual;
I plan to import a few records and need to get the RSC_SCJC used in line 5:
(select max(RSC_RDSS) from SRS_RSC where RSC_SCJC ='0848633/2') as RSC_RDSS,
From the first field RSC_SCJC. Its currently hard coded but I need to pull it in from the first line of teh insert query.
I hope that makes sense and again thanks in advance.
