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

The pl/sql block gets submitted for execution only after the variables get replaced with their values.

So for different values you are submitting different code.

What is wrong in moving the different actions to inside the if/then/else clause?

OK so I've opened an Enhancement Request on this . . . and in the meantime I discovered that I CAN use SQL*Plus substition variables!

The following DOES work:

accept i_label prompt 'Enter CR '

declare

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

begin
dbms_output.put_line (v_crlabel);

if v_cr = 50 then

    goto CR&&i_label;
else

    goto endrun;
end if;

<<CR50>>

dbms_output.put_line('Successfully went to CR50');

<<ENDRUN>>

NULL;
dbms_output.put_line('Went to END');

end;
/

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;
