Dear Sir,

I have these codes
CREATE CURSOR junk (sno n(3),amount n(6))
INSERT INTO junk VALUES (1,500)
INSERT INTO junk VALUES (2,600)
INSERT INTO junk VALUES (3,700)
INSERT INTO junk VALUES (5,800)
INSERT INTO junk VALUES (6,900)
INSERT INTO junk VALUES (7,1000)
INSERT INTO junk VALUES (8,1100)
INSERT INTO junk VALUES (10,1200)
INSERT INTO junk VALUES (11,1300)
In sequence, if found any missing sno then replace the maximum number of sno with missing sno.

In the above example sno=4 is missing and maximum sno is 11
so sno 11 is being replaced with sno 4 and so on.


Please help
