View 16 RepliesI can't understand the following cursor declaration (inside the DECLARE of a PL/SQL block)
CURSOR c_emps IS
SELECT emp_large_ot(empno, ename, job, mgr,hiredate, sal, comm, deptno) FROM emp_large;
emp_large_ot is an object type created as
CREATE TYPE emp_large_ot AS OBJECT
( empno NUMBER
, ename VARCHAR2(10)
, job VARCHAR2(9)
[code]...
and emp_large is similar to the standard emp table
While writing a procedure I went into this problem. Whenever I write Query : Select * from dba_pending_transactions It works fine.
But whenever I use same Select Query inside PL-SQL block it gives error Table or view not exist. Dba_pending_transactions is view.
SQL> declare
2 v_count number(2);
3 begin
4 execute immediate 'select count(*) from dba_ending_transactions' into v_count;
5 dbms_output.put_line(v_count);
6 end;
7 /
declare
*
ERROR at line 1:
ORA-00942: table or view does not exist
ORA-06512: at line 4
Same error I get when i use it inside a procedure.
Im using the following oracle database.
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
PL/SQL Release 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".
CREATE OR REPLACE TRIGGER ETM_AR_IU

FOR EACH ROW
[code]...
All the analysis till now on our system proves that our system is clearly I/O bound and db sequential read is the biggest culprit.
We have even identified the index which is being affected by sequential read. I am thinking of creating a new tablespace with 32K blocksize (currently all table spaces are 8k) and migrate this index to the new space. That way, Oracle will have to do less number of reads to get the required data.
But is there anything wrong in having just one tablespace with a differnt block size? Or is there anything that I have to be watchful about while doing 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 am trying to create an anonymous PL/SQL block to output privilege information for each of the users listed in DBA_USERS In a loop. This is my block so far (not finished):
declare
v_usr varchar2(30);
v_out_header varchar2(100);
[Code]....
The output is as follows:
***User-Role Privilege report***
-----------------------------------
username: ANDREY , profile: DEFAULT
SYSTEM privileges granted directly to the user(not through ROLE) :
no_data_found
A problem I am encountering is that for some users I have no direct privileges that are not granted through roles, And when I have the expression v_qry (which is basically "'select grantee ||'',''|| privilege from DBA_SYS_PRIVS where grantee not in (select role from dba_roles) and grantee ='||'''' ||v_usr||''''") not initialized with values because the select statement retrieved 0 results, I have the process interfered by the no_data_found error/exception.
Questions: how I can preferrably simply, avoid/overcome my problem? Some way to make the loop go on in spite of no data found? maybe something similar to NVL?

For whatever reason, in PHP, DESC statements do not work. They're simply unrecognized and you get an OCI "invalid SQL statement" error. It may be some sort of security feature. I've also had the same result with the SQL scratchpad in the Java EM, but not in SQL Plus. Is there an alternative method for getting details on a table that I can use that also doesn't require being logged in as a SYSDBA?
View 5 Replies View RelatedI am a newbie to Oracle and trying to write something to basically loop through all tables and do a DESC for each table,
I have the following code
set serveroutput on
begin
FOR cursor1 IN (SELECT * FROM ALL_TABLES where OWNER='ABC' ORDER BY TABLE_NAME)
LOOP
DBMS_OUTPUT.PUT_LINE(cursor1.TABLE_NAME);
FOR cursor2 IN (select * from cols where TABLE_NAME=cursor1.TABLE_NAME ORDER BY COLUMN_NAME)
LOOP
DBMS_OUTPUT.PUT_LINE(cursor2.COLUMN_NAME);
END LOOP;
END LOOP;
end;
Although the above code works, I would like to have the DESC TABLE_NAME instead of just displaying the column name so I can see the properties of the column.
I couldn't get the DESC part to work
I am working on ORACLE 9I. I am ordering(ASC/DES) the data one column whose values are
SALES-1
SALES-14
SALES-15
SALES-2
SALES-3
SALES-11
SALES-12
SALES-13
SALES-4
SALES-5
When i do the ascending order dat looks like
SALES -1
SALES-11
SALES-12
SALES-13
SALES-14
SALES-15
SALES-2
SALES-3
SALES-4
SALES-5
but it should display as
SALES-1
SALES-2
SALES-3
SALES-4
SALES-5
SALES-11
SALES-12
SALES-13
SALES-14
SALES-15
if you grant select on a table to a user then u revoke select on this table that user still can desc this table, is this ok? what if i don't want that user to desc it?
View 2 Replies View RelatedThere are 2 setup of Oracle DB 9.2.0.8.0. There is a table T1 in both (one that is working 6.5 million rows and the other that is not working having 6.7 million rows). while doing - select * from t1 order by c1 desc; one is using index i1 and other is going for full table access.
View 1 Replies View Relatedi 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
e.g
item11 item21 item31 chkbox1
item12 item22 item32 chkbox2
Scenario like this :
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 an error with block corruption

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".
The following code works
set serveroutput on
declare
a int;
begin
execute immediate 'select employee_id from employees where first_name=:ab' into a using 'Donald' ;
dbms_output.put_line(a);
end;
but this one doesn't
set serveroutput on
declare
a int;
begin
execute immediate 'select employee_id into :1 from employees where first_name=:2' using a,'Donald';
dbms_output.put_line(a);
end;
Am I not allowed to specify a bind variable with an into clause inside execute immediate ?
I have a cursor returning some value.
for each value returned by the cursor i need to traverse through 31 rows(1 row per day * no of days in the month).
E.g. if cursor returns service_name as xyz then for xyz there can be 31 rows(service may not be used on some days)
I need to go to all of them and take some values and move them to a flat file. how should that be done?

I am trying to create a view of a query that i would be using regularly...the query contains a function call in it...can i use it..
If yes when i try to do it . It gives out an oRa-01031:in sufficient privileges.
I have a dynamic query which i want to run till it return zero records.
I am using WHILE loop for that but it is giving compilation error:
The query is
execute immediate ' Delete from tbl_archive_trade_list
where deal_id in (
select deal_id from tbl_archive_trade_list where trade_id in (
select trade_id from ' || main_trade_group_table || ' where tradegroup_id in (
select tradegroup_id from ' || main_trade_group_table || ' a , tbl_archive_trade_list b
[Code]...
I want to run this Query in While loop till the above command return 0 records.
I tried giving the above statement inside WHILE loop but it is failing.
Without the WHILE loop the above statement works fine and executed properly.
I have question.Using procedure inside the function ?can I get better performance?

I have an application written in Pl SQL Oracle which suppose to send email using utl_smtp. For users that are using Exchange Server 2010 Windows the hyperlinks inside the email are correctly but for users that have a Postfix version installed on a Debian 5 Linux mail server the hyperlinks contains some extra spaces. I think that the CRLF that I'm using inside my code to create the MIME message is not ok interpreted.
