how to genarate random numbers in oracle for particular row?
Answer Posted / nusrath sultana
We can make use of sequence to generate random numbers.
example:
SQL> create sequence seq1 start with 1 increment by 1
maxvalue 100;
SQL>Sequence created.
SQL> create table dup(rollno number(10) primary key,name
varchar2(20) not null);
Table created.
SQL> insert into dup values(seq1.nextval,'&name');
Enter value for name: SAM
old 1: insert into dup values(seq1.nextval,'&name'
new 1: insert into dup values(seq1.nextval,'SAM')
1 row created.
SQL> /
Enter value for name: RAM
old 1: insert into dup values(seq1.nextval,'&name'
new 1: insert into dup values(seq1.nextval,'RAM')
1 row created.
SQL> /
Enter value for name: REENA
old 1: insert into dup values(seq1.nextval,'&name'
new 1: insert into dup values(seq1.nextval,'REENA'
1 row created.
SQL> /
Enter value for name: TINA
old 1: insert into dup values(seq1.nextval,'&name'
new 1: insert into dup values(seq1.nextval,'TINA')
1 row created.
SQL> /
Enter value for name: MONA
old 1: insert into dup values(seq1.nextval,'&name'
new 1: insert into dup values(seq1.nextval,'MONA')
1 row created.
SQL> SELECT * FROM DUP;
ROLLNO NAME
---------- --------------------
1 SAM
2 RAM
3 REENA
4 TINA
