SQL & PL/SQL :: Confirmation Of Statement Execution In Block
Jul 12, 2010
I have a set of sql statements which i have to execute inside a pl/sql block. But i need to know the response of each statement and confirmation whether it is executed successfully.
Practically i need to get info as such in sqlplus status msg for each sql statement
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi PL/SQL Release 10.2.0.4.0 - Production CORE 10.2.0.4.0 Production TNS for Linux: Version 10.2.0.4.0 - Production NLSRTL Version 10.2.0.4.0 - Production
I have one problem in trigger execution. I have a small plsql block in trigger and, I want to execute it as a dynamic way. but it is giving the error. Please find the trigger code. Here my intension is that, the column name used in trigger should be dynamic. In future, if I want to switch the column name, I have to do without modification in trigger. The error im getting is "ORA-01008: not all variables bound".

The stand alone stored procedure has 2 parameter, an IN and OUT...
CREATE OR REPLACE PROCEDURE someprocedure( businessdate IN NUMBER, tablename OUT VARCHAR2)
This procedure has multiple inner blocks. Intention is to control execution of each of the inner blocks basing on the value of flag field obtained from a "processlogtable". This processlog table has structure as below.
I have the below code snippet at the beginning of each inner block that checks value of the flag and then proceeds with execution of that block. The intent is to avoid redundant call of a block that has successfully executed first time. That is, once a specific inner block fails for some reason, the re-execution of the stored procedure should AVOID re-executing the PRIOR successed steps.
I've the code set up as below, but the prior successed block(s) code gets re-executed again once the procedure is re-executed after a failure.
CREATE OR REPLACE PROCEDURE someprocedure( businessdate IN NUMBER,tablename OUT VARCHAR2) CURSOR c_missingtablename IS SELECT datatablename FROM ( SELECT UPPER(datatablename ) TABLE FROM WHERE datatableName IN ('Aaa','BbB','CcC'); [code]....
I have queries on the execution plan of a sql statement
Following is the example
create table t1 as select s1.nextval id,a.* from dba_objects a; create table t2 as select s2.nextval id,a.* from dba_objects a; insert into t1 select s1.nextval id,a.* from dba_objects a; insert into t1 select s1.nextval id,a.* from dba_objects a; insert into t2 select s2.nextval id,a.* from dba_objects a; insert into t2 select s2.nextval id,a.* from dba_objects a; insert into t2 select s2.nextval id,a.* from dba_objects a; commit;
create index i1 on t1(id); create index i2 on t2(id); create index i11 on t1(object_type);
(1) First index on object_type is accessed to get rowids - t1.object_type='VIEW' (2) Then the filter on owner is applied - t1.owner='SYS' (3) Then the table T1 is accessed to fetch data from the rowids returned by the index I11 and filer application - TABLE ACCESS BY INDEX ROWID
Though I am unable to understand how filter can be applied to the rowids retrieved from index, we can see from the plan below that The rows accessed have reduced from 8550 to 1221 before we access the table...Thus filter "t1.owner='SYS'" is applied in between. Right?
another question is
Case 1 - do we retrieve a rowid from index for a given value, then retrieve required values from table for that rowid Thus row at a time in both ... in loop OR Case 2 - we first fetch all rowids from index and then retrieve values from table one row at a time from the collection of rowids fetched?
Suppose Case 1 is what is happening then can we say, both the steps mentioned by IDS 2,3 in plan below are executed exactly equal number of times and the filter "t1.owner='SYS'" is applied at some later stage? Of course in this case the values in ROWS stand misleading then
select * from t1,t2 where t1.id = t2.id and t1.object_type='VIEW' and t1.owner='SYS';

In my code I am using delete statement which is taking too much time to execute.
Statement is as follow:
DELETE FROM TRADE_ORDER_EMP_ALLOCATION T WHERE (ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT) IN (SELECT ARTEMIS_SOURCE_SYSTEM_ID,NM_ARTEMIS_SOURCE_SYSTEM,CD_BOOK_KEY,ACTIVITY_DT FROM LOAD_TRADE_ORDER WHERE IND_IS_BAD_RECORD='N');
Every column in "IN" clause and select clause is containing index on it
Every time no of rows which to be deleted is vary (May be in hundred ,thousand or hundred thousand )so that I am Unable to use "BITMAP" index on the table "LOAD_TRADE_ORDER" column "IND_IS_BAD_RECORD" though it is containing distinct record in it.
Even table "TRADE_ORDER_EMP_ALLOCATION" is containing "RANGE" PARTITION over it on the column "ARTEMIS_SOURCE_SYSTEM_ID". With this I am enclosing table scripts with Indexes and Partitions over it.
way for fast execution in of above delete statement?
Session 1 create table tab1 as select * from dba_objects where object_id is not null; alter session set events '10046 trace name context forever, level 12'; declare x number; begin for i in 1..4 loop
[code]....
Session 2
after "starting" the above pl/sql block from Session 1, I keep on querying tab2 from Session 2 And as soon as 2 records are inserted in tab2, I create index from Session 2
select * from tab2; select * from tab2; select * from tab2; N ---------- 1 2 create index i on tab1(object_id);
As I have tested from a single session (just before this test) such index is used for the sql statement
select count(1) into x from tab1 where object_id=2331;
However when I checked the trace file I am not geeting results as expected
I am expecting 4 execution plans - 2 FTS and 2 Index Access scans and for this I am issuing following command
SELECT COUNT(1) FROM TAB1 WHERE OBJECT_ID=2331 call count cpu elapsed disk query current rows ------- ------ -------- ---------- ---------- ---------- ---------- ---------- Parse 1 0.00 0.00 0 1 0 0 Execute 4 0.00 0.00 0 2 0 0
[code]....
1) Why I am unable to see 4 execution plans - 2 with FTS and 2 with Index access when I mentioned 'aggregate=no'?
2) Whether the index i will be used for last 2 iterations after first 2 iterations of FTS?
If answer to above question 2) is 'No'
By which method I can force an ongoing sql statement in loop to take different execution path? Of course I can't hard parse sql in 'that' current session Will flushing Shared pool work in above case?
Yesterday i got wait event when executed simple select from table.This select was like:
SELECT emp_number from employer where subs_id = 111
I got one row, select is very fast.In our Core Bank System we have package with function which returns such information. I tested this select on test DB, and nothing wrong. But when I executed such select and package on Production DB, DB Admin saw that 88 sessions waits when my session release the resource. But what can happen, it was simple select? I used PL/SQL developer to get information from table:
1) SELECT emp_number from employer where subs_id = 111 then 2) Package with this function
Another users used Oracle Forms screen to execute package. How simple select statement could stop all DB?

I want to execute a DML query with execute immediate statement. That DML query length exceeds 4000 characters. This query has Xquery related conditions, i can not split the query. when i tried execute it is giving "string literal too long". I tried with DBMS_SQL.Parse() and DBMS_SQL.Execute also, but it is giving same error. I have to execute this DML query inside a Procedure. We are using oracle 10g version
I'm trying to create an output statement that will show that the update was successful, but everything that I'm trying doesn't seem to be working.
I have a procedure and an anonymous block that calls on the procedure.
So far after the begin in my anonymous block I have.
BEGIN procedure_name(variable1, variable2); dbms_output.put_line('Successfully Updated'); END;
Now I know that the procedure and the anonymous block without the dbms output works as the update takes place in the table, but I can't get any text string output to confirm this.
I've created a small script witch delete the obsolete and expired backups of RMAN.
The problem is: the "delete obsolete" and the "delete expired backup" command needs a confirmation with YES. I don't need to confirm the command and he deletes the backups directly?
Here is my little script:
#!/bin/ksh export ORACLE_SID=dbtest2 export ORACLE_HOME=/home/oracle/srv/ora/product/11.2.0/dbtest_2 export ORACLE_BIN=/home/oracle/srv/ora/product/11.2.0/dbtest_2/bin alias RMAN=$ORACLE_BIN/rman

If I add another FETCH INTO statement in the while loop block ,I will get the output.why I am getting this error exactly and how another FETCH INTO is preventing it.
how can i track the exception for three select statement in one pl-sql block. here is synario.......
begin select * from emp where empno=1234; --statement 1 select * from cusotmers where cust_id=125; --statement 2 select * from products where product_id='a-3'; --statement 3 end;
i want to track exception any one for ex no_data_found for all these three different statement.
I know if i put this three statement in three different pl-sql sublock then i can trap it....
can we place insert statement in loop inside anonymous block?
CREATE TABLE DEP(DEPTID NUMBER(5) NOT NULL PRIMARY KEY,DNAME VARCHAR2(10),LOCID VARCHAR2(10)); DECLARE I NUMBER(5); BEGIN I := 0; LOOP INSERT INTO DEP VALUES(&DEPTID,'&DNAME',&LOCID); I := I+1; EXIT WHEN I = 5; END LOOP; END;
i have multi data block filed. and checkbox field which based on control block...My task is when i check checkbox only one field should enabled and my mouse goes to that field
My item field based on data block and checkbox based on control block,while i checked chkbox1 , only item31 on that current record should be enabled and i changed value only on that field
when i checked chkbox1 , my cursor goes to item31...not item32
i have a master detail form, In Master block we have one field cheque amount and in Detail block we have field receiveable amount invoice wise. if company paid us a cheque amount we will enter this amount in Master block field Cheque amount and in detail block there will be invoice wise receivable amounts. i want to distribute the cheque amount in detail block invoice wise for example
Cheque amount in master block = 291
Invoice wise receiveable amount is as follows
Invoice No , receivable amount , Received amount
10, 196 , 0 20 , 95 , 0 30 , 54 , 0
Result should be as follows:
Invoice No , receivable amount , Received amount
10, 196, 196 20 , 95 , 95 30 , 54, 0
Received amount field should be distributed according to the receivable amount when recevied amount = cheque amount then remaining will be 0.
I have a multi record control block (basically a text item displaying 6 records) where user enters values and I want to process the values using pre-insert trigger.
I want to read value in each record and then do some tasks using a pre-insert trigger before I commit the values. To navigate between the records I was using first_record, next_record, clear_record built-ins but it gives errors like "40737-illegalrestricted procedure next_record in pre-insert trigger".
HOW to use variable P_TMPLID in following statement
TYPE typ_unrecon IS TABLE OF REC_' || P_TMPLID ||'_UNRECON%ROWTYPE index by binary_integer;
because its throwing error while compiling
and also in statement FORALL i IN unrecondata.FIRST .. unrecondata.LAST SAVE EXCEPTIONS --STRSQL := ''; --STRSQL := ' INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES ' || unrecondata(i); -- EXECUTE IMMEDIATE STRSQL; INSERT INTO REC_' || P_TMPLID ||'_UNRECON VALUES unrecondata(i);---throwing error on this statement commit; --dbms_output.put_line(unrecondata(2).TRANSID); EXCEPTION
In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS') 2 || ' User '||s1.username || '@' || s1.machine 3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text ||' is blocking the SQL statement on '|| s2.username || '@' 4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> ' 6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 , 7 v$session s2,v$sql sqlt1, v$sql sqlt2 8 WHERE s1.sid =l1.sid 9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1 10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2; [code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?
we are executing a load activity every day through .NET Application, we taking a time solt for Database to ensure nobody is using at that time.But the AWR reports showing different issues on different days.

I have a trigger that is called from an update on the table, this trigger performs the procedure and this procedure update the Same record in the table That shot the trigger. this situation returns error ORA-0060 - DEADLOCK DETECTED WHILE WAITING FOR RESOURCE. Is there any way that this works?
In our production environment some SP's are executing longer duration, but when same SP is executed from PLSQL Developer client it is executing vary quickly.
I have question in procedure execution and function execution oracle database. I want know that which is faster in execution procedure or function.
how can i prove it through examples. can i see the explain plan for a procedure and a function or is there any way to prove which one is faster in execution.
We have the following case: an application modifies a table in an Oracle db (10.2.0.3.0).
Unfortunately the update SQL statements from the application always use the condition "where Column1 = 'some given value'" which is wrong (never mind why).
It should be instead "where Column1 = 'some value' and Column2 = 'val for Column2'. The 'val for Column2 will be taken from the very SQL query being issued (we can make the application do an update for Column2 even if the value in it never changes).
So all the update queries from the application look at the moment like that:
"update my_table set Column2 = 'val for Column2', Column3 = 'some other values', Column4 = 'some other value' where Column1 = 'some given value'".
We would like to capture them and somehow on the fly modify them to look like that:
"update my_table set Column2 = 'val for Column2', Column3 = 'some other values', Column4 = 'some other value' where Column1 = 'some given value' and Column2 = 'val for Column2'".
Can a trigger "before update" do it? For some reason we cannot at the moment ask the vendor to change the hard code of the application so we are looking for a temporary workaround.
I have a very big oracle procedure. Since it's too big and calling many other procedures, I am not able to debug the exceptions thrown. Any oracle utility which logs all the procedures called by the master procedure step by step and maintains a detailed record.
I have an understanding that the code written in Forms 6i will be executed by the oracle forms 6i run time on the client machine whether it be a sql/plsql .
e.g. i am using the following query in the procedure( of forms 6i interface ).
insert into emp_remote select ename from emp@db1;
so where the above query would be executed , on client machine or server named db1.
