SQL & PL/SQL :: ANSI To NON-ANSI SQL Conversion
Dec 10, 2010A very simple question yet so difficult...
I have a ansi query...
select * from
tz1
left outer join tz2 on tz1.aa=tz2.cc and tz1.bb is null;
What is the most efficient non-ansi way of writing it?
-----------------script-----------------
create table tz1(aa int, bb int);
create table tz2(cc int, dd int);
insert into tz1 values (1, 100);
insert into tz1 values (2, 200);
insert into tz1 values (3, 300);

SQL & PL/SQL :: TRUNC And PLW-07204 (conversion Away From Column Type)
Nov 22, 2010how I can avoid PLW-07204 "conversion away from column type may result in sub-optimal query plan" (or rather the problem notified here by Oracle) from my PL/SQL code.My code looks as follows:
create table T(D date);
create or replace procedure P is
cursor C(D_IN IN DATE) is
select D
from T
where trunc(D)=SYSDATE;
begin
null;
end P;
[code]...
I don't want to disable the warning - it is there for a reason.
Additional description for the issue: It seems that D is of typ=12, while trunc(D) is of typ=13. You can use DUMP to read this info. This is described at URL....

Oct 9, 2013 Use ANSI standard JOIN syntax for example i have this code.

View 2 Replies View RelatedSQL & PL/SQL :: ANSI Join Returning Wrong Dataset?
May 25, 2011...continued from "Problems with full outer join"I think that ANSI joins in Oracle doesn't work correctly. Or am I doing something wrong? The query looks like this:
select nvl(k.id_pers,t.id_pers) id_pers, k.dat_avst
, id_trans, dat_trans
from
( select ka.id_pers, ka.dat_avst, ka.dat_nasta_avst
[code]...
It's a full outer join between one table (with a subquery) and an inline view with two tables You can see the returned rows in the listing below. The query returns one row where there is a match between t_trans and t_kontoavst.It also returns two rows from table t_kontoavst with no correspondence in t_trans.Finally it returns 26 rows from the table t_trans with no correspondence in t_kontoavst. But among them there are many rows in contradiction to the conditions:
and trunc(dat_trans) >= to_date('20040101','yyyymmdd')
and trunc(dat_trans) <= to_date('20050604','yyyymmdd')
Actually it seems to return all the 27 rows in t_trans (one of them joined to t_kontoavst).These conditions are actually not part of the join so I changed it to:
where trunc(dat_trans) >= to_date('20040101','yyyymmdd')
and trunc(dat_trans) <= to_date('20050604','yyyymmdd')
It's not clear to me if this where condition belongs to the joined result or just to the right joined inline view.With this change the correct rows from t_trans where returned but unfortunately the two rows from t_kontoavst with no correspondence in t_transdisappeared. I thought maybe that is because dat_trans is null for these two rows after the join. Therfore I also includeddat_trans to be null. This can only happen when t_trans is missing
where dat_trans is null
or (trunc(dat_trans) >= to_date('20040101','yyyymmdd')
and trunc(dat_trans) <= to_date('20050604','yyyymmdd'))
But that didn't change the result I have also tried right and left joins and it produces similar errors.One other thing i tried was to replace the inline view with one of the underlying tables t_trans. But the result was the same.Data returned from the original query (see query above):
ID_PERSDAT_AVSTID_TRANSDAT_TRANS

View 7 Replies View RelatedTruncate Partition From PL/SQL Package
May 8, 2013I have an Oracle Package with a procedure in which
package with a procedure in which there is a truncate partition, ALTER TABLE table_name TRUNCATE partition_name DROP STORAGE and the all is run with an EXECUTE IMMEDIATE 'alter table ...' .
The point is that the procedure in the package is started from another DB via DB Link (schema USER1) and doesn't work because of lack of privileges.
Instead, if the same procedure is started as a procedure, standalone, not in the package but from the same user (USER1) it works perfectly.
Don't understand why and which privileges must give to the user to run the procedure from inside the package.

SQL & PL/SQL :: Truncate Partition - Resource Busy?
Sep 1, 2010i have one procedure that run at same time for two different partition.In the begin of the processes i do the truncate partition and after that the insert of data in the partition.Since i have two processes running at the same time, i will fill up data in two different partition.
But it occurred one error :
"ORA-00054: resource busy and acquire with NOWAIT specified"
The problem is caused by the truncate partition. I'm doing two simultaneous execution of the same process, but when one process is doing the truncate other is insert data.How can i do the truncate of this two partition, or insert in to, without get any error. I think the two simultaneous insert is not a problem.
So how can i lock the table in the first truncate and after that release the table for the next truncate?

Also is there any way to know that how many rows/blocks a select statement is scanning because of the effect of HWM even the table has 0 rows.
