oracle - Why does dbms_sql.parse containing incorrect PL/SQL block with bind variables succeed unexpectedly? -

-



the pl/sql block below fails expected:

sql> declare   2    int;   3  begin   4    := dbms_sql.open_cursor;   5    dbms_sql.parse(i,'begin dontexist; dbms_output.put(''a''); end;',1);   6    dbms_sql.close_cursor(i);   7  end;   8  / declare * fout in regel 1: .ora-06550: regel 1, kolom 7: pls-00201: identifier 'dontexist' must declared. ora-06550: regel 1, kolom 7: pl/sql: statement ignored. ora-06512: in "sys.dbms_sql", regel 1120 ora-06512: in regel 5

because don't have procedure called dontexist. question why next pl/sql block complete successfully?

sql> declare   2    int;   3  begin   4    := dbms_sql.open_cursor;   5    dbms_sql.parse(i,'begin dontexist; dbms_output.put(:a); end;',1);   6    dbms_sql.close_cursor(i);   7  end;   8  /  pl/sql-procedure geslaagd.

the difference use of bind variable instead of constant, i'd know why makes difference.

this oracle 12.1.0.2

looks parse syntactic anon blocks binds, , full semantic check deferred until execution.

still, that's not behaviour want bug 26669757 raised.
