Home -> Community -> Mailing Lists -> Oracle-L -> & symbol in PL/SQL
I don't write much PL/SQL as so it took many years before I ran into this one. Pardon me is this is well known. Tested in 7.3.4 \& 9iR2
SQL> show define
define "&" (hex 26)
SQL> -- Comment line with & symbol in it
SQL> declare
2 c varchar2(1);
3 begin
4 select 'R' into c from dual;
5 -- comment line with a & symbol in it
6 -- comment line with a \& symbol escaped
7 dbms_output.put_line(c);
8 end;
9 /
Enter value for symbol: e
old 5: -- comment line with a & symbol in it
new 5: -- comment line with a e in it
R
PL/SQL procedure successfully completed.
Why does the PL/SQL parser interpret the define symbol before comment delimeters? So one can't comment out a line of PL/SQL code containing a & without also using the escape? And worst of all, I can't use the & as shorthand for AND in my embedded comments. Open a TAR. Call out the National Guard.
