Allowing qualified procedure names to be used without the CALL keyword:
BEGIN
test.p1(10);
test.p2;
END;
Note:
- COMMIT and ROLLBACK cannot be used in a direct assignment anymore:
COMMIT:= 10;
ROLLBACK:= 10;
But as they are reserved keywords in Oracle anyway, this is not a problem.
- SHUTDOWN now also cannot be used in direct a direct assignment:
SHUTDOWN:=10;
If this causes migration problems in the future, the grammar should
be modified.
Note:
Variables with names COMMIT, ROLLBACK and SHUTDOWN can still be assigned
with the SET statement, e.g. SET COMMIT=10;
The crash happened because of a wrong reset_lex() .. restore_lex() sequence.
The Item in WHERE clause and the corresponding sp_instr_jump_if_not() were
erroneously created using different LEX.
This is a fix for "MDEV-10580 sql_mode=ORACLE: FOR loop statement"
The tokenizer now treats digits followed by two dots (e.g. '1..')
as an integer number '1' followed by DOT_DOT_SYM.
Previously this sequence was treated as a double number '1.' followed by '.'.
as this type of SHOW is only available in debug builds.
A bug in b7af3e704dd7800638ef677e9d921ad3e467a9a6.
All SHOW FUNCTION CODE queries should be in compat/oracle.sp-code.
Fixed that the ITERATE statement inside a FOR LOOP statement did not
increment the index variable before jumping to the beginning
of the loop, which caused the loop to repeat endlessly.
Part 5: EXIT statement
Adding unconditional EXIT statement:
EXIT [ label ]
Conditional EXIT statements with WHERE clause
will be added in a separate patch.
- Part 9: EXCEPTION handlers
The top-most stored routine blocks now support EXCEPTION clause
in its correct place:
AS [ declarations ]
BEGIN statements
[ EXCEPTION exceptions ]
END
Inner block will be done in a separate commit.
- Part 14: IN OUT instead of INOUT (in SP parameter declarations)
Part 13: RETURN vs RETURNS in function definition:
CREATE FUNCTION f1(a INT) RETURN INT ...
Part 12: No parentheses if no arguments:
CREATE FUNCTION f1 RETURN INT ...
Part 12: No parentheses if no arguments
Now "CREATE PROCEDURE p1 AS" is supported with no parentheses after the name.
Note, "CREATE FUNCTION f1 AS" is not supported yet, due to grammar conflict
with UDFs. Functions will be done in a separate patch.
Part 9: EXCEPTION handlers
- Adding exception handler syntax:
WHEN exception_name THEN statement
- Adding EXCEPTION section intoi the top BEGIN..END SP block.
Note, currently EXCEPTION goes in the beginning of the top BEGIN..END
SP block.
TODO:
- add EXCEPTION section into inner blocks
- move EXCEPTION to the end of the block
