I am unable to use simple SELECT statement to initialize a variable.

```
DECLARE
A VARCHAR2(10);
BEGIN
A := (SELECT FIRST_NAME FROM FIMS_OWNER.EMPLOYEE_T WHERE WWID = 'NA734');
END;
/

```

ERROR:

```
[Error] Execution (4: 11): ORA-06550: line 4, column 11:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:

   ( - + case mod new not null <an identifier>

   sum variance execute forall merge time timestamp interval

   * & - + ; / at for mod remainder rem <an exponent (**)> and
   or group having intersect minus order start union where
   connect || multiset

```

And if it's not possible, what's the alternative for the same.

**PS**: I am using such query to set the variable(and later use it) with my cursor which takes the `WWID` dynamically and then changes the value accordingly.
