Execute immediate -- udpate statement

Hello,
I am fairly new to scripting sql..pl/sql.. any help will be really appreciated!!
I have a table where i am trying to update one of the column with table name i am passing dynamically.
However i get the invalid identifier error. ORA-00904. The column AD.MIR_PARENT i am updating is of compatible data type.
Any help please.. where i am doing a mistake..
fyi -- the reason i am updating the column with table name is because i need to know which table i make a hit.

Just about everything you are doing is a mistake.
1. You using PL/SQL instead of SQL to do this job? That is usually a red flag that something is wrong about what you are trying to do or how you are trying to do it.
2. You are 'fairly new to scripting' and have chosen to use dynamic sql? That is one of the harder techniques to learn and to use properly and is another red flag. Experienced professionals often don't use dynamic sql properly and often use it when they shouldn't.
3. You are using a loop to execute against multiple tables? It is extremely difficult to perform proper error handling and recovery when you do this. What if some of the tables get updated and others don't? How will you know which ones still need to be updated? How will you roll back the data if you need to.
4. You have opened a GIGANTIC opportunity for sql injection where the wrong tables could accidentally be updated. That could corrupt the data and reek havoc on the system. Anyone could, accidentally or intentionally, put the wrong schema, table or column in your lookup table and cause enormous damage.
5. You are using double quotes in PL/SQL? Where did you learn that?
            WHERE EXISTS (select "'||p_table || '" from "' || P_SCHEMA||'"."'||p_table || '" where "' || P_column ||'" = ad.acct_id ) Finally, it is standard practice when you do have a use case for dynamic sql to construct the query in a variable and then print the query or write it to a log file so it can be tested independently.
If you do that you will likely see your error.
query VARCHAR2(4000);
query := 'UPDATE . . .';
execute immediate query;SUMMARY: don't try to automate something until you can first do it manually. Write a query that works properly first. Then, and only then, convert it to dynamic sql.

How to use using clause in execute immediate statement??

Hi ALL,

This is the code which I have written...
declare

execute immediate 'truncate table forall_test';
forall i in v_rectype.first..v_rectype.last
execute immediate 'insert into forall_test values :1' using v_rectype(i);
commit;
end;

Thatmeans using statement cannot be a non sql type.True: You need an sql type for this:
e.g. with
create or replace type emp_typ
as
   object (empno number (4),
           ename varchar2 (10 byte),
           job varchar2 (9 byte),
           mgr number (4),
           hiredate date,
           sal number (7, 2),
           comm number (7, 2),
           deptno number (2))
create or replace type emp_tab as table of emp_typ
/you can do
--- an empty test table

   select *

                   comm,
                   deptno)
   bulk collect into emp2_tab
   from emp
   where empno like '77%';
-- forall loop
   forall c in 1 .. emp2_tab.count
      execute immediate 'begin

How to run a EXECUTE IMMEDIATE statement in a Interactive Report

Hello all!!
I need to make a dinamic construction of a query to execute in a Interactive Report, but the Region Source only allows simple SELECT statements. There is any way to run a EXECUTE IMMEDIATE statement in a Interactive Report Region Source?
Regards Pedro.

Thank you Andy for your reply.
I have been testing for a while the use of a collection in the interactive report but i am unable to load data in the interactive report.
I created the collection successfully in the SQL Commands with the code:
declare
v_sql varchar2(32000);
begin
v_sql:='select ename, job from emp';
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY('coleccao_emp',v_sql,'NO' );
end;
I tested successfully the creation of the collection with the query:
SELECT c001, c002
FROM APEX_collections
WHERE collection_name = 'COLECCAO_EMP'
My problem is: the data of the collection are returned in the SQL Commands but when i run the query statament in an interactive report, report or even a Pl/Sql region in my application the data aren't displayed, only the message (No data found).
Can someone explain why, besides the collection is populated the interactive can not print the results.
Regards Pedro.

Table does exist and user executing the statement has the proper privileges (i've even executed the contents of "execute immediate" by hand and it works fine)
What am I missing?
Thanks in advance.

CREATE TEMPORARY TABLE USING EXECUTE IMMEDIATE

Hi All,
i have a question,
how can i create a temporary table using EXECUTE IMMEDIATE ??
Like:
CREATE GLOBAL TEMPORARY table new_table as (Select * from old_table);
Thanks,
Edited by: xDeviates on Jun 11, 2012 3:13 PM

It looks like you are approaching the problem incorrectly. As I suggested in Dynamic Select, it sounds like you, at most, want a function that returns a SYS_REFCURSOR (it's still not obvious to me why you would even want/ need to resort to dynamic SQL in the first place)
CREATE OR REPLACE FUNCTION get_dynamic_cursor( p_table_name IN VARCHAR2 )
RETURN sys_refcursor
IS
l_rc sys_refcursor;
BEGIN
OPEN l_rc FOR 'SELECT * FROM ' || dbms_assert.sql_object_name( p_table_name );
RETURN l_rc;
END;which you can then call from your application
SQL> variable rc refcursor;
SQL> exec :rc := get_dynamic_cursor( 'EMP' );
PL/SQL procedure successfully completed.
SQL> print rc

Execute Immediate. Insert from materialized view.

Hi,
I'm using Execute Immediate in a function to insert rows into a table. (Oracle 10G) The function in tern is used in a materialized view. So, effectively the view does an insert.
When I just had a regular insert statment the view would not compile. When I changed the insert statment into the execute immediate it started working.
Here are my questions:
1. Do I need a commit or execute immediate does it automatically? When I create my view that calls the function it looks like the rows do get inserted as expected. But I couldn't find documentation that explains whether execute immediate does the commit.
2. Is there a drawback to using execute immediate in a function that is used in a materialized view? Is there other way to insert rows from a materialized view? Can I call a stored procedure instead of a function in a materialized view?
Your help is greatly appreciated.
Thanks
NK

there are things that I'm not able to question yet :)It's a lot easier to write decent programs if we understand the why of the requirement as well as the what. I think you will create a better impression in your new job if you demonstrate some liveliness of thought and personality - by asking questions - rather than merely following orders.
The question I proposed is not necessarily a hostile one (I can think of at least one good reason for doing what you've been asked to do). Broadening your knowledge of your new system is a good thing in its own right. But you never know, asking the right question may prevent you doing unnecessary work.
Cheers, APC

Dbma_scheduler job executing procedure that loops through all client schemas in the database rolls back transaction incase of exception

Hi,
Needed your inputs on approach to implement a job using dbms_scheduler.
We have around 2000 schemas. Each schema has a package with 2 procedures.
The requirement is to create a single job in SYS that would loop through each schema and run the procedures at a specific time ( once a day) and send email notification on success or failure.
Job script:
BEGIN
    dbms_scheduler.create_job( job_name=> 'LOAD_EACH_SCHEMA_AUDIT_DATA',
                               job_type=>'PLSQL_BLOCK',

                                END;',
                               start_date=>systimestamp,

I was able to execute the job successfully. However, when a schema procedure (SCHEMA_01.pkg_audit_info.p_load_COA) throws an exception, the job fails and all transaction is rolled back.
Is there a way to loop through each schema and execute the related procedures. Even if exception happens, it should rollback only for that schema and continue the other schemas in the loop?
Please let me know if there is a better way to achieve this. Is the way i am handling exceptions in the job/procedure correct?

Hi,
RAISE_APPLICATION_ERROR will cause the program to exit back to the caller, even if you place it in a block within the loop, so the RAISE or RAISE_APPLICATION_ERROR instruction should be placed in your "pkg_audit_info.p_load_AM" and "pkg_audit_info.p_load_coa" procedures. This way, you can use a block inside the loop and log the error.
FOR i IN
    ( SELECT username FROM dba_users WHERE username LIKE 'ABCFIRM%'
    LOOP
       BEGIN
        vstmt:= 'begin ' || i.username || '.pkg_audit_info.p_load_coa; end;';
        EXECUTE immediate vstmt;

Delete From More than 1 table without using execute immediate

Hi,
Am new to PL/SQL, I had been asked to delete few of the table for my ETL jobs in Oracle 10G R2. I have to delete(truncate) few tables and the table names are in another table with a flag to delete it or not. So, when ever I run the job it should check for the flag and for those flag which is 'Y' then for all those tables should be deleted without using the Execute Immediate, because I dont have privilages to use "Execute Immediate" statement.
Can anyone help me in how to do this.
Regards
Senthil

Then tell you DBA's, or better yet their boss, that they need some additional training in how Oracle actually works.
Yes, dynamic sql can be a bad thing when it is used to generate hundreds of identical queries that differ ony in the literals used in predicates, but for something like a set of delte table statements or truncate table statements, dynamic sql is no different in terms of the effect on the shared pool that hard coding the sql statements.
This is a bad use of dynamic sql, because it generates a lot of nearly identical statements due to the lack of bind variables. It is the type of thing your DBA's should, correctly, bring out the lead pipe for.
DECLARE
   l_sql VARCHAR2(4000);
BEGIN
   FOR r in (SELECT account_no FROM accounts_to_delete) LOOP
      l_sql := 'DELETE FROM accounts WHERE account_no = '||r.account_no;
      EXECUTE IMMEDIATE l_sql;
   END LOOP;
END;This will result in one sql statement in the shared pool for every row in accounts_to_delete. Although there is much else wrong with this example, from the bind variable perspective it should be re-written to use bind variables like:
DECLARE
   l_sql VARCHAR2(4000);
   l_acct NUMBER;
BEGIN
   FOR r in (SELECT account_no FROM accounts_to_delete) LOOP
      l_sql := 'DELETE FROM accounts WHERE account_no = :b1';
      EXECUTE IMMEDIATE l_sql USING l_acct;
   END LOOP;
END;However, since you cannot bind object names into sql statements, the difference in terms of the number of statements that end up in the shared pool between this:
DECLARE
   l_sql VARCHAR2(4000);
BEGIN
   FOR r in (SELECT table_name, delete_tab, trunc_tab
             FROM tables_to_delete) LOOP
      IF r.delete_tab = 'Y' THEN
         l_sql := 'DELETE FROM '||r.table_name;
      ELSIF r.trunc_tab = 'Y' THEN
         l_sql := 'TRUNCATE TABLE '||r.table_name;
      ELSE
         l_sql := NULL;
      END IF;
      EXECUTE IMMEDIATE l_sql;
   END LOOP;
END;and something like this:
BEGIN
   DELETE FROM tab1;
   DELETE FROM tab2;
   EXECUTE IMMEDIATE 'TRUNCTE TABLE tab3';
END;or this as a sql script
DELETE FROM tab1;
DELETE FROM tab2;
TRUNCTE TABLE tab3;is absolutley nothing.
Note that if you are truncating some of the tables, and wnat/need to use a stored procedure, you are going to have to use dynamic sql for the truncates anyway since trncate is ddl, and you cannot do ddl in pl/sql wiothout using dynamic sql.

You are already executing it by using:
execute immediate rtrim(vSql,',')||' from emp';What you probably want is to display results, right? Then you can either use bulk collect into clause in execute immediate or use cursor variable. Bulk collect example:
set serveroutput on
declare
vSql varchar2(3000);
type emp_rec_tbl_type is table of emp%rowtype;
emp_rec_tbl emp_rec_tbl_type;
begin
vSql:='SELECT ';

   loop
     vSql:=vSql||i.column_name||',';
   end loop;
   dbms_output.put_line(rtrim(vSql,',')||' from emp');
   execute immediate rtrim(vSql,',')||' from emp' bulk collect into emp_rec_tbl;
   for i in 1..emp_rec_tbl.count loop
     dbms_output.put_line(rpad(emp_rec_tbl(i).ename,10) || emp_rec_tbl(i).sal);
   end loop;

How to make my Execute Immediate statement to work??

Hi, Sir:
I use SQL Oracle 9i,
I have following procedure called by a trigger:
CREATE OR REPLACE PROCEDURE emps_check IS
s_sql VARCHAR2(500);
BEGIN
DBMS_OUTPUT.PUT_LINE('1. Start to Delete all rows in the emps' );
delete from emps;
DBMS_OUTPUT.PUT_LINE('2. Start to insert into emps from emp' );
s_sql:='INSERT INTO Emps(EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) select EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO from emp;';
DBMS_OUTPUT.PUT_LINE('3. s_sql= ' || s_sql );
EXECUTE IMMEDIATE s_sql;
DBMS_OUTPUT.PUT_LINE('3. Procedure call OK, Employ Name ' );
EXCEPTION
-- Use this to trap the ORA-00942: table or view does not exist
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('Procedure call Exception: Employ Name ' );
end emps_check;
My trigger is:
CREATE OR REPLACE TRIGGER emps_biu_after
after INSERT OR UPDATE or delete on emp
for each row
begin
if TO_CHAR(SYSDate,'DY')= 'SUN'
then
DBMS_OUTPUT.PUT_LINE('Today is holiday, ename =' );
else
DBMS_OUTPUT.PUT_LINE('Today is working Day, ename =');
emps_check();
end if;
end;
When I use following to update emp table:
SQL> UPDATE emp T1
2 SET T1.sal = 200.0
3 WHERE T1.ename like '%SCOTT%';
I got:
Today is working Day, Trigger Call Procedure emps_check()
1. Start to Delete all rows in the emps
2. Start to insert into emps from emp
3. s_sql= INSERT INTO Emps(EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO) select EMPNO,ENAME,JOB,MGR
Procedure call Exception: Employ Name
Trigger Call Procedure emps_check() Success
Looks like EXECUTE IMMEDIATE s_sql; did not work.
What is wrong??
How to make my Execute Immediate statement to work??
Thanks

You may omit the ';' character...
s_sql:='INSERT INTO
Emps(EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO)
select EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM,DEPTNO
from emp';
... and something else
IN PL/SQL when a procedure , function doews not take
any parameter(s) then its call can be made as simply
its name without a pair of parenthesis....(It seems
that you are influenced by Java...:) )
SimThanks Sir:
I remove this ; but still error:
1 UPDATE emp T1
2 SET T1.sal = 768.1
3* wHERE T1.ename like '%SCOTT%'

Equivalent for execute immediate command in maxdb

hi all,
like in oracle for executing the sql_query, we have execute immediate command.
for e.g.. in oracle
L_SQL ='SELECT * FROM EMP';
EXECUTE IMMEDIATE L_SQL;
what will be the command for execute immediate in MaxDB??
like in MaxDB
L_SQL = 'SELECT * FROM EMP';
Now How can i execute the above l_sql variable in MaxDB.
thanks, Bhupinder

Hi Bhupinder,
the following code snippet should do the job
[code]
CREATE DBPROC EXAMPLE
AS
VAR statement1 char(100);
SET statement1 = 'SELECT * from DBA.DUAL';
TRY
EXECUTE statement1;
CATCH IF $rc <> 100
THEN STOP ($rc, 'unexpected error');
[/code]
Best regards,
Marco

How to display result of execute immediate on sql prompt

I wish to create a dynamic select statement where i will give table name and where condition as input parameters at runtime. for this i created following procedure:
CREATE or replace PROCEDURE select_rows (
table_name IN VARCHAR2,
condition IN VARCHAR2 DEFAULT NULL)
AS
where_clause VARCHAR2(100) := ' WHERE ' || condition;
BEGIN
IF condition IS NULL THEN where_clause := NULL; END IF;
EXECUTE IMMEDIATE 'select * FROM ' || table_name || where_clause;
END;
my procedure is successfully created.
my problem is how to get select stmt output at screen (sql prompt)
or how to spool the output in a file.
plz. help me. I am learning oracle .
thanx in adv.

You could use refcursors. Example :
TEST@db102 > CREATE or replace PROCEDURE select_rows (
2     table_name IN VARCHAR2,
3     condition IN VARCHAR2 DEFAULT NULL,
4     cur1 out sys_refcursor)
5 AS
6     where_clause VARCHAR2(100) := ' WHERE ' || condition;
7 BEGIN
8     IF condition IS NULL THEN where_clause := NULL; END IF;
9     open cur1 for 'select * from '||table_name||where_clause;
10 END;
TEST@db102 > /
Procedure created.
TEST@db102 > var cur refcursor;

Error while insert data using execute immediate in dynamic table in oracle

Error while insert data using execute immediate in dynamic table created in oracle 11g .
first the dynamic nested table (op_sample) was created using the executed immediate...
object is

mark1 number,
mark2 number
t_sub_mark is a class of type sub_mark
CREATE OR REPLACE TYPE ASI.t_sub_mark is table of sub_mark;

nested table is created below:
begin
EXECUTE IMMEDIATE ' create table '||op_sample||'

now data from sam1 table and object (subject_obj) are inserted into the dynamic table
declare
subject_obj t_sub_mark;
begin
subject_obj:= t_sub_mark();
EXECUTE IMMEDIATE 'insert into op_sample (select id,name,subject_obj from sam1) ';
end;
and got the below error:

then when we tried to insert the data into the dynam_table with the subject_marks object as null,we received the following error..
execute immediate 'insert into '||dynam_table ||'

887684 wrote:
ORA-00904: "SUBJECT_OBJ": invalid identifier
ORA-06512: at line 7The problem is that your variable subject_obj is not in scope inside the dynamic SQL you are building. The SQL engine does not know your PL/SQL variable, so it tries to find a column named SUBJECT_OBJ in your SAM1 table.
If you need to use dynamic SQL for this, then you must bind the variable. Something like this:
EXECUTE IMMEDIATE 'insert into op_sample (select id,name,:bind_subject_obj from sam1) ' USING subject_obj;Alternatively you might figure out to use static SQL rather than dynamic SQL (if possible for your project.) In static SQL the PL/SQL engine binds the variables for you automatically.
