Error in plsql function

Question

Hi Friends,
I have the below plsql function which is throwing error.
The below function is written in Apex, so kindly let me know ow to resolve this error
The below query checks the existing value and if null assigns a value by select statement. else will assign it back to the variable.
Function:
BEGIN
IF
:P1_VARIABLE_NAME IS NULL THEN :P1_VARIABLE_NAME:=select .... from .... (which returns a string value)
ELSE
:P1_VARIABLE_NAME
END
END
Error:
Encountered the symbol "SELECT" when expecting one of the following: ( - + case mod new not null avg count current exists max min prior sql stddev sum variance execute forall merge time timestamp interval date pipe

No I am creating a PLSQL function body option to write the above query. Is there a way in apex to dynamically bind the valueApex function bodies support bind variables. For example, you can set the rendering condition of an Apex region to a function body and code it as follows:
if :P1_SOMEVAR = MySchema.MyFunction( :P1_SOME_OTHERVAR ) then
  return( true );
else
  return( false );
end if;Where the bind variables used are standard Apex page item (variables).
I also suggest that if your questions are Apex related and not specifically PL/SQL and SQL language related, you rather ask your questions in the OTN Apex forum and not here.
