Answer / rinson

Nobody mentioned errors..(both runtime and compile time)

let's go through the errors

A. compile time errors

1. Encountered symbol "‘" when expecting single qoutes
double quotes etc.
2. When we replace all these symbols to single quotes
next error -- > empno must be declared will come,
since it is to be declared in cursor C1.Here they
may be expecting ename instead of empno.
3. Then it will show next error-->
Numeric or value error since nvl function contains
different datatypes.we can change this to 0.

Now all compile time errors removed.

B. Run Time Errors

1. Since cursor for loop implicitly open,fetch and close
cursor , there is no need to close cursor in second if
condition.Actually compiler will not allow to close a
cursor in a cursor for loop.

it will throw the run time error
ora-01001 invalid cursor.
By removing close c1; all errors will be removed.

PL/SQL code without any errors is exact as given above
by Ramprasad.

Thanks

Answer / intejar ahmad

invalid single quotes and cursor does not selecy empno

Answer / radha sri seshu.kolla

WHEN YOU ARE USING CURSOR WIH FOR LOOP NO NEED TO SPECIFY
CLOSE CURSOR.
SINGLE CORES ARE LOOKING AS IF THEY ARE SINGLE CORES, BUT
THEY ARE SPECIAL CHARACTERS.
YOU ARE USIGN NVL FUNCTION IN THIS. YOU GAVE FIRST ARGUMENT
AS NUMBER DATATYPE, AND SECOND IS CHARACTER DATA TYPE. 0
AND O LOOK LIKE SAME JUST IT IS TO CONFUSE THE CANDIDATES.
