Home -> Community -> Mailing Lists -> Oracle-L -> RE: slightly OT: visual c++ and null values
Hi,
>From the book:
EXEC SQL BEGIN DECLARE SECTION;
int emp_number;
float salary, commission;
short comm_ind; /* indicator variable */
EXEC SQL END DECLARE SECTION;
char temp[16];
float pay; /* not used in a SQL statement */
...
printf("Employee number? ");
gets(temp);
emp_number = atof(temp);
EXEC SQL SELECT SAL, COMM
INTO :salary, :commission:ind_comm
FROM EMP
WHERE EMPNO = :emp_number;
if(ind_comm == -1) /* commission is null */
pay = salary;
else
pay = salary + commission;
