Insert Using SELECT & Sub-SELECT

Question

Hi All,
I am trying to insert records into a table using SELECT statement. The SELECT statement has a Sub-SELECT statement as follows:
INSERT INTO table1(c1,c2,c3,c4,c5)
SELECT c1,c2, (SELECT MAX(C3)+a1.c3
FROM table1
WHERE c1 = var1
AND c2 = a1.c2
GROUP BY c3),c4,c5,
FROM table1 a1
WHERE c1 = var1
The above works fine when run from SQL*PLUS but gives compilation error when included in PL/SQL pacakge.
I am using Oracle 8.1.7.
Could you any one please tell me if I have missed something?
Thanks,
Satyen.

In 8i, you will need to use dynamic SQL to execute this statement because the PL/SQL parser does not understand all SQL syntax (including SELECT in a column list).
execute immediate
  'INSERT INTO table1(c1,c2,c3,c4,c5)' ||
  ' SELECT c1, c2, (SELECT MAX(C3)+a1.c3 FROM table1 WHERE c1 = :var1 AND c2 = a1.c2 GROUP BY c3), c4, c5' ||
  '   FROM table1 a1 WHERE c1 = :var1' using var1, var1;
