Redirect data to another table using before insert trigger.

Dear all,
How can I redirect the data to another table in a before Insert trigger? My database is Oracle10g.
I have a table EMP (EMP_ID, LAST_NAME, SALARY).
I have another EMP_COPY table with the same structure. I also have a before Insert trigger on the EMP table.
Based on a condition that I have to redirect the data in table EMP_COPY. Let's say the condition is EMP_ID = 100.
I fire an insert on EMP table for example INSERT IN EMP(EMP_ID,LAST_NAME,SALARY) VALUES(100,'Dev',500).
On the inside of the front Insert trigger on the EMP table, I have the code
IF EMP_ID = 100 THEN
INSERT INTO EMP_COPY (EMP_ID, LAST_NAME, SALARY)
VALUES(:NEW.) EMP_ID,: NEW. LAST_NAME,: NEW. SALARY);
COMMIT;
ON THE OTHER
NULL;
END IF;
But the problem here is that data goes to EMP table of origin also although I don't want. He should do an Insert into EMP table only if EMP_ID! = 100.

One way has been to raise a user-defined exception inside the If statement and not handle it so that the original insert on table EMP fails but INSERT comes in the EMP_COPY table. But in this solution since the inside the trigger unhandled exception, it propagates to the calling environment. And I can't stand outside relaxation as the calling environment is a form of Oracle Apps standard that cannot be customized.

Any kind of help will be highly appreciated that I am fighting for more than two weeks.

Thanks in advance
Dev

Remove the autonomous transaction pragma... and then try again.

SQL Loader loading data into two Tables using a single CSV file

Dear all,
I have a requirement where in I need to load the data into 2 tables using a simple csv file.
So I wrote the following control file. But it loads only the first table and also there nothing in the debug log file.
Please suggest how to achieve this.
Examples of data
Source_system_code,Record_type,Source_System_Vendor_number,$vendor_name,Vendor_site_code,Address_line1,Address_line2,Address_line3
Victor, New, Ven001, Vinay, Vin001, abc, def, xyz

Record_type tank "ltrim (rtrim (:Record_type)),"
Source_System_Vendor_number tank "ltrim (rtrim (:Source_System_Vendor_number)),"

Address_line3 tank "ltrim (rtrim (:Address_line3)).
)
the problem here is loading into a table, only the first. (Table 1)
Please guide me.
Thank you

When you do not provide a starting position for the first field in table2, it starts with the following after a last referenced in table1 field, then it starts with vendor_site_code, instead of $vendor_name. So what you need to do instead, is specify position (1) to the first field in table2 and use the fields to fill. In addition, he dislikes when 1 = 1, and he didn't need anyway. See the example including the corrected below control file.

Is inserting form temporary table in another table uses tablepsace temp?
Hi all

I am inserting data in the temporary table in ds_info.
I am inserting data of 16.5 GB size in the table.
I have 15 GB of temp tablespace.
Please confirm have I not enough space TEMP_TS.

OR
Please clarify the question.
Is temp tablespace uses comes in insert statement.

Thanks in advance,
An insert into a table when querying an another table/tables can involve the use of the TEMP tablespace:
If the INSERTION involves either
a. ORDER BY
b. GROUP BY
c. a JOIN between two or more source tables that is run like a Hash Join OR as a merge join and sorting operation
d. ADDING an indicator on the target index table being present on the target table (fusion of the index for new lines entries is postponed if an ADDITION is used)

There now things are clear... whenever I have free I'll post the code u how to do this...

for now, a few tips can help u

-create the table to store operations travel so then u can't fix your code

-Create the cursor on the T1 line through all the records.

-Control what empno and action i.e. the current cursor (I or O) exists on the same date in T2 or not

-otherwise exists insert a new record check also the SHIFT is coming in time IF is between MAJ 0815 and 1645 and action is 'I' then insert record and column values accordingly

s ' there is, then update the record of the place where empno = cur.empno and attendance_date = mydate;

Check out the following tutorials OBE, that explains the creation of GET and POST RESTful Web Services and how to use them in the APEX.
- Creation and use of RESTful Web application services Express 4.2
- Creation and use of RESTful Web application services Express 5.0
Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

Of course, you'll want to change the types of data, etc. as needed.

I assumed that the XML can contain several "" sections and that each section can contain several entries.

Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

CDATA stuff are handled automatically by SQLX (XML functionality integrated into Oracle's SQL)

To access the EFS data from another disk using original certificates/keys

I use EFS on a Workgroup XP - Pro, SP3 and have backed up keys. I am trying to access the files on this disk now mounted in another machine (also SP3 of XP - Pro and in a working group). I can load the certificates of the first machine in the second machine by double clicking it. Once the certificates are loaded, how decipher you? I get "Access denied" when I right click and try to decrypt the files on the original drive. The MS help talk about designating a "File Recovery Agent", but this procedure seems to be to area of machines and gets a bit fuzzy for working groups. BTW, I'm testing my file recovery process. No data is at risk. Can you tell me FAQ to decrypt a file on a disk that is moved to another machine using the original (REC & PFX files) encryption certificates/keys?

Select this OPTION to generate XML data from the table using XMLELEMENT, XMLAGG gives error ORA-19011 string buffer too small

I need to use the REEL spool the resulting XML data of the SELECT query.
SQL is a standard in my org, but I can do with a PL/SQL solution also to load data into a table (cannot use a COIL with PL/SQL)
What I do is:
1. a column of type CLOB to a xml_report of the loading of the above SELECT query table
2. Then using SELECT * FROM xml_report to SPOOL the data to a file report.xml
No need of XMLTYPE data behind. Xml data stream is fine for me.
In addition, I need to validate the XML file, also using XSD.
Problem is that the resulting lines of the select query are supposed to be from 15000 to 20000 bytes long.

It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)

You use the right method.

There is an implicit conversion from XMLType to the data type VARCHAR2 as expected by the function TO_CLOB, where the limitation, and the error.

To serialize XMLType to CLOB, use the XMLSerialize function:

SELECT XMLSerialize (DOCUMENT

XMLELEMENT ("accounts",

...

)

)

OF ANY_TABLE;

For the rest of the requirement, I wish you good luck trying to spool the XML correctly.

You may need to play around with the SET LONG and SET LONGCHUNKSIZE commands to operate.

Select table data in another table
Hello

I want to select data from A table, which is not in table B.

Currently I am doing:

Select
smofnut,
nameA,
dobA
a.
If smofnut not in
(select A snoB, B).
where smofnut = snoB
and nameA = Name)

But above all it is very slow.

I can do something like:

Select
smofnut,
nameA,
dobA
of A, B
where
EXCLUDE (smofnut = snoB and nameA = Name)

Please note that I need the place where the condition on the two columns.

any help will be appreciated.

-Harvey
What are approximate data to A and B?
What is 'very slow '?
What version of Oracle?
What is the query plan?

Without knowing anything about your system, my first thought would be to see if a NOT EXISTS happened to be faster for your data
```
SELECT snoA,
       nameA,
       dobA
  FROM a
 WHERE NOT EXISTS (
    SELECT 1
      FROM b
     WHERE a.snoA = b.snoB
       AND a.nameA = b.nameB )
```
Of course, I don't know why you want to join A & B in your NOT IN subquery. It would seem that you would need just a subquery correlated, i.e.
```
SELECT snoA,
       nameA,
       dobA
  FROM a
 WHERE snoA NOT IN (
    SELECT snoB
      FROM b
     WHERE a.snoA = b.snoB
       AND a.nameA = b.nameB )
```
This should be more efficient than the original request. The NOT EXISTS version may or may not be more effective than NOT IN according to data volumes.

Before Insert TRIGGER to create partitions problem
Hello

I m having a problem with the following situation in Oracle 8i:

I have a table TEST_TABLE, which is divided by the beach with a DATE column. The idea is to have a partition for each month, so the HIGH_VALUE of partitions is always the first day of the month following that represents the partition.

I created a BEFORE TRIGGER INSERT on the table TEST_TABLE, which tests if the partition for the month of registration which is being inserted exists and, in case it doesn´t, a PROC AUTONOMOUS_TRANSACTION is called to create the TRIGGER.

Running the code below one can see that even if partitions are created as expected, when you try to insert a record with a date greater than the last partition for the first time, this error is returned:
ORA-14400: inserted partition key exceeds plu legal partition key.

Note that if you run the same statement again insert, it s inserted correctly on the partition that was created the first try.

I´ll appreciate any help on this matter.

INSERT INTO TABLE_TEST VALUES (1, TO_DATE ('2008-12-31 23:59:59 ',' YYYY-MM-DD HH24:MI:SS'));))

-Returns the error on the first try
INSERT INTO TABLE_TEST VALUES (2, TO_DATE ('2009-01-01 00:00:01 ',' YYYY-MM-DD HH24:MI:SS'));))

----------------
It is the use of the pragma AUTONOMOUS TRANSACTION. Your current transaction cannot see the result of this DOF since it occurs outside of the current transaction. The clue is in the name.

Of course, you cannot run the DDL in a trigger without use of this pragma, so you're pretty much stuck. There is a solution in 11g, but that will not help you. Unfortunately, your only option is to pre-create the partitions required in front of the need. For example, you might have a DBMS JOB to create a partition for the next month, which takes place the last day of each month (or logical date of company).

Update of the data in the Table using XMLTYPE DATA

I did insertions using XMLTYPE data but have never done it and update. Can someone give me some advice?
PROCEDURE ADD_LABORDER_CODES)
IN_ORDERCODESXML IN CLOB DEFAULT NULL,
Number of OUT OUT_AFFECTEDROWS
)
AS
X SYS. XMLTYPE;
BEGIN
X: = SYS. XMLTYPE. CREATEXML (IN_ORDERCODESXML);
INSERT INTO MAINT_LABORD_CODES)
INSERT INTO MAINT_LABORD_CODES)
LABORD_CODE_ID,
COMPENDIUM_ID,
ORDER_CODE,
ORDER_DESC,
ACTIVE,
TIMESTAMP,
MODIFIED_BY)
SELECT MLOCDS_SEQ. NEXTVAL,
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/COMPENDIUM_ID') AS COMPENDIUM_ID,
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/ORDER_CODE') AS ORDER_CODE,
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/ORDER_DESC') AS ORDER_DESC,.
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/LOINC_CODE') AS LOINC_CODE,
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/ACTIVE') AS ACTIVE.
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/TIMESTAMP') AS TIMESTAMP.
EXTRACTVALUE (VALUE (MLOC), '/ ORDERCODE/MODIFIED_BY') AS MODIFIED_BY
TABLE (XMLSEQUENCE (EXTRACT(X,'/ORDERCODES/ORDERCODE'))) NMCO;
OUT_AFFECTEDROWS: = NUMBER OF ROWS SQL %;
EXCEPTION
WHILE OTHERS THEN
dbms_output.put_line (SQLERRM);
RAISE_APPLICATION_ERROR (-20001, SQLERRM);
END;

Example of use of the FUSION-

If the line exists in the target table (based on the COMPENDIUM_ID and ORDER_CODE values), the UPDATE is, if not to INSERT:
```
declare

  in_ordercodesxml  clob :=
  '
  
    500
    696231
    ABO Group & Rh Type
    NULL
    12345
    Y
    2014-08-13
    1
  
';

begin

  merge into maint_labord_codes t
  using (
    select compendium_id
         , order_code
         , order_desc
         , loinc_code
         , active
         , timestamp
         , modified_by
    from xmltable('/ORDERCODES/ORDERCODE'
           passing xmltype(in_ordercodesxml)
           columns COMPENDIUM_ID    number(10)    path 'COMPENDIUM_ID'
                 , ORDER_CODE       varchar2(50)  path 'ORDER_CODE'
                 , ORDER_DESC       varchar2(250) path 'ORDER_DESC'
                 , LOINC_CODE       varchar2(10)  path 'LOINC_CODE'
                 , ACTIVE           varchar2(1)   path 'ACTIVE'
                 , TIMESTAMP        date          path 'TIMESTAMP'
                 , MODIFIED_BY      number(10)    path 'MODIFIED_BY'
         )
  ) x
  on (     t.compendium_id = x.compendium_id
       and t.order_code = x.order_code )
  when matched then update
    set t.order_desc = x.order_desc
      , t.loinc_code = x.loinc_code
      , t.active     = x.active
      , t.timestamp  = x.timestamp
      , t.modified_by = x.modified_by
  when not matched then insert
  (
    labord_code_id
  , compendium_id
  , order_code
  , order_desc
  , loinc_code
  , active
  , timestamp
  , modified_by
  )
  values (
    mlocds_seq.nextval
  , x.compendium_id
  , x.order_code
  , x.order_desc
  , x.loinc_code
  , x.active
  , x.timestamp
  , x.modified_by
  );

end;
/
```
Also note that I used XMLTABLE instead of TABLE/XMLSEQUENCE, which is much easier to use (and not deprecated in the latest versions).

You have not precisely the date format in the TIMESTAMP element so I assumed a conform to W3C.

If you have a problem with this part, return to a projection of VARCHAR2 and use TO_DATE with actual size.

Copy a column of data in another table?
Hello world

I am a beginner SQL who spent ridiculous amounts of time trying to find a solution to a problem no doubt very simple.

I have two tables composed of 162000 lines each. A table has the following format:

table T1

PID NUMBER
NUMBER OF PG
NUMBER OF PCS
PS NUMBER
NUMBER OF PL
NUMBER OF DRIFTWOOD

(coercion, but a simple data)

The DRIFTWOOD column is empty, all the others are completely filled.

The other table is filled only one column:

table T2

NUMBER OF CALCULATEDCHANCE

My intention is to copy all the rows in the column T2 CALCULATEDCHANCE in the column CYBERJER from T1.

Insert will not work because it adds records. I tried to use the update, but maybe I don't get the syntax right. All I got is to copy the first value of DRIFTWOOD in all lines of CALCULATEDCHANCE.

Thanks in advance for your answers!
Try
```
update T2
set calculatedchance = dbms_random.value(0,100);
```

Update of the data in the table using LAG/LEAD
Hello!

I have a table that looks like:

CREATE TABLE CUSTOMER_INFO_TEST
(
ACCOUNT_NUM VARCHAR2 (40 BYTE),
PHONE VARCHAR2 (100 BYTE),
E-MAIL VARCHAR2 (300 BYTE),
DATE OF START_DT,
DATE OF CHANGE_DT,
END_DT DATE
);

The example data:

INSERT INTO CUSTOMER_INFO_TEST VALUES ('BOB', 555-1234', ", TO_DATE ('2011-01-01', 'YYYY-MM-DD'), TO_DATE ('2011-01-06', 'YYYY-MM-DD'), TO_DATE ('2011-01-10', 'YYYY-MM-DD'));
INSERT INTO CUSTOMER_INFO_TEST VALUES ('BOB', 555-1234', ' BOB@GMAIL.) COM', TO_DATE ('2011-01-01', 'YYYY-MM-DD'), TO_DATE ('2011-01-11', 'YYYY-MM-DD'), NULL);
INSERT INTO CUSTOMER_INFO_TEST VALUES ('BOB', 555-1234', ' BOB@GMAIL.) COM', TO_DATE ('2011-01-01', 'YYYY-MM-DD'), TO_DATE ('2011-01-15', 'YYYY-MM-DD'), NULL);
INSERT INTO CUSTOMER_INFO_TEST VALUES ('JACK', 555-4321', ", TO_DATE ('01-03-2011', 'YYYY-MM-DD'), TO_DATE ('2011-03-06', 'DD-MM-YYYY'), NULL);
INSERT INTO CUSTOMER_INFO_TEST VALUES ('JACK', 555-4321', ' JACK@GMAIL.) COM', TO_DATE ('01-03-2011', 'YYYY-MM-DD'), TO_DATE ('2011-03-11', 'YYYY-MM-DD'), NULL);

My question:
How can I configure end_dt (if null), to the next change_dt minus one

It shows what I want to do:

Select the rowid, account_num, phone, e-mail, start_dt, change_dt, end_dt, nvl (end_dt, lead (change_dt-1, 1) over (partition by account_num of start_dt order)) enddt CUSTOMER_INFO_TEST where end_dt is null;

So, I want to update the table itself with the date in enddt. But how do I do this?

This must be done in a single statement...

Thanks in advance

Richard

Please post sample data!
If your query returns the desired results, you can use the MERGE:
```
SQL> select *
  2  from   customer_info_test;

ACCOUNT_NU PHONE      EMAIL                     START_DT CHANGE_D END_DT
---------- ---------- ------------------------- -------- -------- --------

BOB        555-1234   [email protected]             01-01-11 11-01-11
BOB        555-1234   [email protected]             01-01-11 15-01-11

JACK       555-4321   [email protected]            01-03-11 11-03-11

5 rows selected.

  6        ) b
  7  on (a.rowid = b.rid )
  8  when matched then update set a.end_dt = b.new_end_dt;

4 rows merged.
