Thread: A QUESTION ABOUT evaluation of two-dimensional Associative Arrays

A QUESTION ABOUT evaluation of two-dimensional Associative Arrays

From

Hello

This is Robin.

I'm learning about the package of Enterprisedb.

I wrote a package like:
CREATE OR REPLACE PACKAGE BODY pkg_test_d2
IS


TYPE t_d2_tab IS TABLE OF integer INDEX BY integer;
TYPE t_d2_arr IS TABLE OF t_d2_tab INDEX BY integer;

v_D2_Value t_d2_arr;
v_D2_Max integer DEFAULT 0;


PROCEDURE xxx(INOUT xxxx) IS
BEGIN
  ...
  cnt := 1;
  LOOP
   cnt := cnt + 1;
  IF XXX

   v_D2_Value(v_D2_Max)(cnt) := 0;
   END IF;
   ....
  
  

But it can not be excused.
I modified v_D2_Value(v_D2_Max)(cnt)  to v_D2_Value[v_D2_Max][cnt].
So it can be load in to database.
When the package be excused,an error occured.

I need a way to give a value to the variable v_D2_Value  directly,which like v_D2_Value(v_D2_Max)(cnt) := 0  .

Could you give me some advice please?

 

Best Regards

Hello. First, can you reproduce the error without the PACKAGE? As in just CREATE TYPE and CREATE PROCEDURE statements? If so, what are the errors?

And I think you mean "executed" instead of "excused".

Hi,

Below query can be handy to find unused indexes.

select indexrelname from pg_stat_user_indexes where idx_scan = 0 and idx_tup_read = 0 and idx_tup_fetch = 0 ;

Hope it helps.

Thanks.

how about  the case as follows?

idx_scan = 0 and idx_tup_read = 0 and idx_tup_fetch = 0, but
idx_blks_read is not 0 and idx_blks_hit is not 0
?

regards

Maintaining an unused index still requires its blocks to be read.

Cheers,
