User input with accept and promp - oracle

Question

I need to do a report with a procedure of every salesman in 6 fake companies if they sold more then the number the user entered. i'm in sql developper with a oracle Db.
I asked to ppl in my class how they did and the thing they did doesnt work for me, i always get error on the accept/prompt.
/
accept temp default '100';
/
when '&temp' < 90.00 then raise too_cold;
I also tried using it like that:
accept temp prompt 'Input degree (numerically in degrees F)?:';
I want to show a prompt with words so that the user knows what to enter and use the number i get.

Answer 1

Help yourself.
SQL> help accept
ACCEPT
------
Reads a line of input and stores it in a given substitution variable.
ACC[EPT] variable [NUM[BER] | CHAR | DATE | BINARY_FLOAT | BINARY_DOUBLE]
[FOR[MAT] format] [DEF[AULT] default] [PROMPT text | NOPR[OMPT]] [HIDE]
Here we go:
SQL> set ver off
SQL>
SQL> accept temp number default 20 prompt 'Enter department number: '
Enter department number: 10
SQL> select deptno, ename from emp where deptno = &temp;
DEPTNO ENAME
---------- ----------
10 CLARK
10 KING
10 MILLER
SQL>
If nothing's entered, the default value takes place:
SQL> accept temp number default 20 prompt 'Enter department number: '
Enter department number:
SQL> select deptno, ename from emp where deptno = &temp;
DEPTNO ENAME
---------- ----------
20 SMITH
20 JONES
20 SCOTT
20 ADAMS
20 FORD
