Hello all
here is new version of CHECK FUNCTION patch
I changed implementation of interface:
* checked functions returns table instead raising exceptions - it
necessary for describing more issues inside one function - and it
allow to use better structured data then ExceptionData
postgres=# select lineno, statement, sqlstate, message, detail, hint,
level, "position", query from plpgsql_checker('f1()', 0, '{}', false);
lineno | statement | sqlstate | message
| detail | hint | level | position | query
--------+---------------+----------+--------------------------------------------+--------+--------+-------+----------+----------------------
4 | SQL statement | 42703 | column "c" of relation "t1" does
not exist | [null] | [null] | error | 15 | update t1 set c = 30
7 | RAISE | 42P01 | missing FROM-clause entry for
table "r" | [null] | [null] | error | 8 | SELECT r.c
7 | RAISE | 42601 | too few parameters specified for
RAISE | [null] | [null] | error | [null] | [null]
(3 rows)
* result of CHECK FUNCTION is simple table (like EXPLAIN - based on
Tom proposition)
postgres=# check function f1();
CHECK FUNCTION
------------------------------------------------------------------------
In function: 'f1()'
error:42703:4:SQL statement:column "c" of relation "t1" does not exist
query:update t1 set c = 30
^
error:42P01:7:RAISE:missing FROM-clause entry for table "r"
query:SELECT r.c
^
error:42601:7:RAISE:too few parameters specified for RAISE
(8 rows)
This change allow a more playing with output
postgres=# check function all in schema public;
CHECK FUNCTION
────────────────────────────────────────────────────────────────────────
In function: 'bubu(integer)'
error:42703:2:assignment:column "v" does not exist
query:SELECT a + v

query:SELECT 1,1
In function: 'f1()'

query:SELECT r.c

error:42601:7:RAISE:too few parameters specified for RAISE
