Title: RE: Can I use "GOTO" with variables in PL/SQL?

you can do this (called as indirect referencing) within pl/sql using dynamic sql.

Bill,

Sadly, I don't think this is possible. The PL/SQL compiler is just not that
dynamic.

Pretty cooleo idea, though.

Good day, all:

I'm writing a script where the user can specify at run-time if they want to
run the entire script or just one numbered piece. One way I thought of
implementing this is pasted below, but the line "goto v_crlabel" is not
recognized - evidently the PL/SQL engine is not substituting in the value
for the variable.

Does anyone know if this is possible? If not, I can just prefix each block
by an if..then statement to test for the value in v_cr . . . but I thought
it could be cool to try it this way.

Thanks
bill

***************************************************************

accept i_cr prompt 'Enter CR to run: '

declare

v_cr number := &&i_cr;
v_crlabel varchar2(30) := 'CR' || to_char(v_cr);

begin

if v_cr is not null then
goto v_crlabel;
else
goto endrun;
end if;

<<CR5>>
dbms_output.put_line('Successfully went to CR5');
goto endrun;

<<CR6>>
dbms_output.put_line('Successfully went to CR6');
goto endrun;

<<CR7>>
dbms_output.put_line('Successfully went to CR7');
goto endrun;

<<ENDRUN>>
NULL;
dbms_output.put_line('Went to ENDRUN');

end;
/
