Re: Lexical Variable use in Cursor

The ampersand is specific to SQL*Plus:
SQL*Plus> select * from dual where dummy = '&my_variable'; Enter value for my_variable: X
D
-
X
You can use it in a PL/SQL script (The code format is for non-standard):
SQL*Plus> declare cursor cur is
2 select * from dual where dummy = '&my_variable';
3 plsql_var varchar2(1);
4 begin open cur;
5 fetch cur into plsql_var;
6 dbms_output.put_line( plsql_var);
7 close cur;
8 end;
9 .
SQL*Plus> set serveroutput on
SQL*Plus> /
Enter value for my_variable: X
X
PL/SQL procedure successfully completed.
But it may not work as you wish in a stored procedure (again, don't copy the line format):
SQL*Plus> create or replace procedure mikejunk is
2 cursor cur is select * from dual where dummy = '&my_variable';
3 plsql_var varchar2(1);
4 begin open cur;
5 fetch cur into plsql_var;
6 dbms_output.put_line( plsql_var);
7 close cur;
8 end;
9 /
Enter value for my_variable: X
Procedure created.
SQL*Plus> execute mikejunk;
X
PL/SQL procedure successfully completed.
I hope this is what you were looking for!
