RE: Can I use "GOTO" with variables in PL/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;
/
