Help with IMMEDIATE EXECUTION

Hello people can help you Execute Immediate below set out? I'm a little confused on how to use it.

#!/bin/sh

sqlplus -s ${DB_USER} << EOF


SELECT 'ALTER TABLE PANDORA.'||table_name||' DROP PARTITION '||partition_name||';'
FROM user_tab_partitions
WHERE TABLE_NAME IN ('SIU', 'NGME')
AND partition_name = (SELECT MIN(partition_name) 
                      FROM user_tab_partitions
                      WHERE TABLE_NAME IN ('NGME')
                      AND partition_name <> 'DUMMY'
                      );
                                  
SELECT 'ALTER TABLE PANDORA.'||table_name||' ADD PARTITION WEEK'||TO_CHAR(TO_NUMBER(REPLACE(partition_name,'WEEK'))+1)||';'

                      WHERE TABLE_NAME IN ('NGME')
                      AND partition_name <> 'DUMMY'
                      );

EXIT

Thank you in advance.

Something like

BEGIN

I'm IN)

SELECT table_name, nom_partition

Of user_tab_partitions

WHERE TABLE_NAME IN ("SIU", "NGME")

AND nom_partition = (SELECT MIN (partition_name)

Of user_tab_partitions

WHERE TABLE_NAME IN ("NGME")

AND nom_partition <> 'DUMMY '.

)

) LOOP

RUN IMMEDIATELY "ALTER TABLE PANDORA." | i.table_name |' DROP PARTITION '. i.PARTITION_NAME;

END OF LOOP:

END;

  • Changing table via the package with immediate execution (problem)

    Hello

    I have a unusual problem. I have a package that contains the procedure that via execute immediate statement, creates a table on which he performs different actions for example:

    -alter table some_owner.dummy_table noparallel

    -create index some_owner.idx_name on some_owner.dummy_table (column)...

    But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.

    Note If call these commands outside the package (a simple script) this all done OK.

    I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.

    I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.

    There must be a problem why a package cannot change the table which is owned by the user 'SOME_OWNER '.

    All useful responses would be appreciated.

    I have a unusual problem.

    No - you don't have. This question has been answered SEVERAL times on this forum and others.

    But I only managed to run move and create synonym table/public via execute immediate statement. Actions as alter table and create index fails with error ORA-01031: insufficient privileges.

    OK - your username doesn't have privileges to do these operations or only received privileges through roles.

    Roles are DISABLED in named PL/SQL blocks that use of the AUTHOR's rights.

    Note If call these commands outside the package (a simple script) this all done OK.

    I found a way, where I set the AUTHID CURRENT_USER command create package statement. In this way all the actions executed OK.

    Of course - the roles are NOT disabled in named PL/SQL blocks that use the rights of the APPELLANT or in anonymous blocks.

    I wonder why I can't change the table via the package with immediate execution on a table that is in the tablespace "SOME_TABLESPACE" and the title of owner "SOME_OWNER", without putting the AUTHID command on the package.

    Well now you know!

  • Procedure failed with ORA-01403, associated with immediate execution, captured

    This procedure compiles without error. Its purpose is to copy the sequence of one schema to another object. After it failed with ORA-01403, I added exception code of capture (see the comments in the code).

    A few notes:

    1. I started the proceedings with exec copy_sequence ('ADDRESS_SEQ', 'SST', 'TEST1');

    2. the first sql string is built correctly since I can see in the console output:

    Select last_number in the all_sequences where sequence_owner = upper('TSS') and upper('ADDRESS_SEQ') = sequence_name

    I can run this SQL command, and returns a real value;

    Here is the procedure

    SET SERVEROUTPUT ON;

    create or replace procedure copy_sequence (seq VARCHAR2, prod_schema VARCHAR2, VARCHAR2 test_schema)

    as

    Val number (21);

    s_sql varchar2 (200);

    Start

    s_sql: = ' select last_number in the all_sequences where sequence_owner = upper('''|| prod_schema ||'') ') and sequence_name = upper('''||) Seq | " ')';

    -immediate' select last_number in the Vale of all_sequences where sequence_owner = upper('''|| prod_schema ||'') ') and sequence_name = upper('''||) Seq | " ')';

    Dbms_output.put_line ('sql 1 ' | s_sql);

    execute immediate s_sql in val;  ---!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The code does not work here!

    Dbms_output.put_line ('val' |) Val);

    s_sql: = 'delete the sequence'. test_schema |'. ' || FF.;

    Dbms_output.put_line ('sql 2 ' | s_sql);

    -execution immediate s_sql;

    s_sql: = 'create the sequence'. test_schema |'. ' || Seq |' minvalue maxvalue 1 999999999999999999999 begin by ' | Val | 'increment of 1';

    This result is coming as FPD4 has 2 as a value, then there will be two records to the result with column date (DT).
    Your query is perfect only thing is that I have to go to connect the name of the column immediately above as below;

    AND FPD = 'FPD14'
CONNECT BY LEVEL <= SPTS;

    So, if possible, please let me know is there a better way to spend the column name, to get the correct data.

    Well, we don't have any example for working with information and the expected results of these data in the example, then it is very difficult for us to understand exactly what is affected by the query.

    What happens if you delete the connection by clause? Why must you connect him by clause in your query? It is not clear what you include that for (like I said).

    Is chr (39) a quote on your system?

    Did you try my example or something else?
    (I've tried before, I posted it).

    Here is a complete example.
    I changed it to my previous post to use a variable binding to remove the tank (39).
    It will also help if lvalue contains a quote.

    Hi all

    I use Oracle Forms 10 g. I have a remote database and I've created a database link to the db. Now, I need to update some data in this database from my system using forms. To do this, I wrote a statement such as:

    run immediately "SELECT GLH_CODE_SEQ. NEXTVAL@WB IN '. GLHCODE | ' THE DOUBLE '.   (glh_code_seq is a sequence in remote db)

    then I changed the statement

    forms_ddl ("SELECT GLH_CODE_SEQ. NEXTVAL@WB IN '. GLHCODE | (' DOUBLE ');

    Now that the error is not burst but the variable is not under any value.

    The same statement (forms_ddl) works fine on sql * more.

    Someone please help me if I do something wrong or suggest if anything to do about it.

    Hello
    Try to print the offending instruction using exception, I used small test cases by changing the pl/sql block, you may need to change to respond to all other types of data in this table.

    CREATE TABLE semantics$
AS
   SELECT USER AS owner,
          table_name,
          data_type AS s_data_type,
          column_name,
          data_length AS s_char_length
   FROM cols
   WHERE table_name = 'MY_OBJECTS';

DECLARE
   CURSOR c1
   IS
      SELECT *
      FROM semantics$;

   v_statement   VARCHAR2 (255);
   v_nc          NUMBER (10);
   v_nt          NUMBER (10);
BEGIN
   EXECUTE IMMEDIATE 'select count(*) from semantics$' INTO v_nc;

   EXECUTE IMMEDIATE 'select count(distinct table_name) from semantics$'
      INTO v_nt;

   DBMS_OUTPUT.put_line(   'ALTERing '
                        || v_nc
                        || ' columns in '
                        || v_nt
                        || ' tables');

   FOR r1 IN c1
   LOOP
      v_statement   := 'ALTER TABLE ' || r1.owner || '.' || r1.table_name;
      v_statement   := v_statement || ' modify (' || r1.column_name || ' ';
      v_statement   :=
         v_statement || r1.s_data_type || '(' || r1.s_char_length;

      IF (r1.s_data_type = 'NUMBER')
      THEN
         v_statement   := v_statement || '))';
      ELSE
         v_statement   := v_statement || ' CHAR))';
      END IF;

      DBMS_OUTPUT.put_line (v_statement);

      -- EXECUTE IMMEDIATE v_statement;
   END LOOP;

  • Need help with EXECUTE IMMEDIATE

    I'm tring to issue an EXECUTE IMMEDIATE to create a DIRECTORY. My problem is that I'm in the "'... ''...'' '...'' ' mess!

    source_instance VARCHAR2 (30);
    Select sys_context ('USERENV', 'DB_NAME') in the double source_instance;

    IMMEDIATE EXECUTION
    ' CREATE OR REPLACE DIRECTORY "DATA_HUB_". source_instance LIKE "/ mnt/smb/share/layout scene/DataHub /" | source_instance';

    I am hopeing to get:
    CREATE or REPLACE DIRECTORY DATA_HUB_MYDB AS ' / mnt/smb/share/layout DataHub/scene/MYDB ";

    I'm on Oracle 11.1


    Thank you!

    I wonder why people do not use q' syntax. It was introduced in 10g

       EXECUTE IMMEDIATE q'#CREATE OR REPLACE DIRECTORY DATA_HUB_#' || source_instance || q'# AS '/mnt/smb/share/Staging/DataHub/#' || source_instance || q'#'#';

  • Update in immediate execution with rownum

    Can I put in an UPDATE by immediate execution that only maximum 10 lines will be updated?

    It is:
       EXECUTE IMMEDIATE 'UPDATE A_PAZIENTI_ESAMI SET  '||
                    ' NREFERTO      = :1, '|| 
                    ' DATA_REFERTO  = :2, '||

                    ' DATA_EROGAZ   = :4, '|| 
                    ' STATO_REFERTO = :5, '|| 
                    ' MEDICO_E      = :6  '|| 
                    ' WHERE '|| WHERE_CLAUSE_ESA  
--
|| ' and rownum <= 10'   -- this is my doubt

--

   USING    AP_REFERTOB.NREFERTO,
                    AP_REFERTOB.DATARF, 
                    EXTRACT (YEAR FROM AP_REFERTOB.DATARF) ,
                    AP_REFERTOB.DATAEROGA,

    Thanks in advance

    Hello
    your query works very well. It updates only the first 10 rows based on the place where the condition.
