trigger for the insert statement

Hello.
I have a table, say, with 3 columns: ID, NAME, NAME_LENGTH.
I am trying to create a trigger that fires when a record is inserted in the table.
I send values for the ID and NAME columns per INSERT statement. and I need the trigger to write the LENGTH OF THE NAME INSERTED in the 3rd column

CREATE OR REPLACE TRIGGER schema_name. GENERATE_length
AFTER INSERT ON table_name
FOR EACH LINE
DECLARE
F NVARCHAR2 (200);
L NUMBER (5);
NL NUMBER (5);
NUMBER OF ID_LENGTH (5): = 5;
BEGIN
F: =:New.Name;

L: = LENGTH (F);

UPDATE HR_ORG_TREE

SET name_length = NL;

END;

but does not work. error occurres as...

ORA-04091: table schema_name.table_name is changing, the function of triggering/can not see
ORA-06512: at the 'schema_name '. GENERATE_length', line 13
ORA-04088: error during execution of trigger ' schema_name. GENERATE_length'

Thank you.
Sara

CREATE OR REPLACE TRIGGER schema_name.GENERATE_length
    -- is "table_name" real name of your table?
    AFTER INSERT ON table_name
    FOR EACH ROW
BEGIN
    -- this update will change all rows in HR_ORG_TREE table
    -- specify WHERE for this update
    UPDATE HR_ORG_TREE
       SET name_length = LENGTH(:NEW.name);
END;

Suppose your table_name is HR_ORG_TREE and you need to calculate the length of the name for just inserted row
After maybe the code will be useful (not tested)

CREATE OR REPLACE TRIGGER schema_name.GENERATE_length
    BEFORE INSERT ON HR_ORG_TREE
    FOR EACH ROW
BEGIN
    :new.name_length := LENGTH(:NEW.name);
END;

Good luck

Of course, it is possible. According to what the text file looks like to, you can create an external table that treats the text file as if it were a table. Otherwise, you can always read the file in PL/SQL, using the utl_file package and INSERT of PL/SQL commands.

You have problems whatever you wantt? If so, your zip code and explain what the problem is.

Whenever you have any questions, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the exact results you want from these data, so that people who want to help you can recreate the problem and test their ideas. In this case, also post a small sample of the text involved file.

If you ask about a DML operation, such as INSERT, then INSERT statements, you post should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.

Explain, using specific examples, how you get these results from these data.

Always say what version of Oracle you are using (for example, 11.2.0.2.0).

How can I write the trigger for the global temporary Table

Hi Grus,
How can I write the trigger for the global temporary Table.

I created the TWG with trigger using the script below.

CREATE A GLOBAL_TEMP GLOBAL TEMPORARY TABLE
(
EMP_C_NAME VARCHAR2 (20 BYTE)
)
ON COMMIT PRESERVE ROWS;

CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP
BEFORE DELETE, UPDATE OR INSERT
ON GLOBAL_TEMP
REFERRING AGAIN AS NINE OLD AND OLD
FOR EACH LINE
BEGIN
INSERT INTO VALUES EMPNAME (: OLD.) EMP_C_NAME);
END;
/

trigger was created successfully, but her would not insert EMPNAME Table...

Please guide if mistaken or not? If not wanting to give a correct syntax with example

Thanks in advance,
Arun M M

BEGIN
INSERT INTO EMPNAME VALUES (:OLD.EMP_C_NAME);
END;

you are referencing old value in insert stmt.

BEGIN
INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
END;

then run your app, it works very well...

CREATE GLOBAL TEMPORARY TABLE GLOBAL_TEMP
(
EMP_C_NAME VARCHAR2(20 BYTE)
)
ON COMMIT PRESERVE ROWS;

CREATE OR REPLACE TRIGGER TRI_GLOBAL_TEMP
BEFORE DELETE OR UPDATE OR INSERT
ON GLOBAL_TEMP
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
BEGIN
dbms_output.put_line(:OLD.EMP_C_NAME||'yahoo');
INSERT INTO EMPNAME VALUES (:new.EMP_C_NAME);
dbms_output.put_line(:OLD.EMP_C_NAME);
END;
/

create table EMPNAME as select * from GLOBAL_TEMP where 1=2

insert into GLOBAL_TEMP values('fgfdgd');
commit;
select * from GLOBAL_TEMP;
select * from EMPNAME;

output:
1 rows inserted
commit succeeded.
EMP_C_NAME
--------------------
fgfdgd               

1 rows selected

EMP_C_NAME
--------------------
fgfdgd

Sorry, I don't understand what you want.
You say you want to write something in a HOLD file instead of insert? Of course, you can do it. Change the INSERT statement in a SELECT statement and add commands to the COIL.

Question related to the INSERT statement
Imagine this scenario:

-table_a has 5 000 000 records at time t1

-table_b is empty at time t1

-At time t1, I execute the following statement:
```
          insert into table_b
            select * from table_a;
    
```
-L' insert statement ends in time t2

-Between t1 and t2, say 3 000 new records have been added to the table_a (by OLTP processes).
Thus, at time t2, table_a has 5 003 000 records.

My question is, at time t2, the number of records will be in table_b? Will it 5,000,000 or
5 003 000 or somewhere between these two counts?

I guess it will be 5,000,000 because that is the number when the insert statement
has started to run.

Any comment is appreciated.

At time t2, it is possible that the answer is 0. Once the insert operation finishes (can be any time after t1 in your example, possibly before t2, possibly after) and assuming you checked in the same session where you run the insert, you would see 5 000 000. In other sessions you would continue to see 0 up to what the session who made the done insert one COMMIT.

Looking for a better style or a way to write the INSERT statement, possible with brand of continuation

Honestly, I really looked everywhere for this.
The problem is that, while tinkering in SQL Developer and knowing that in the spreadsheet I can just execute individual instructions by placing the cursor on the SQL statement I want to run I tried to do an INSERT query that would allow me to run an INSERT statement for... Well many inserts.
I thought I could use a brand of continuation but nothing I've tried has worked.
INSERT INTO
HF_easy_drinks
VALUES
("Blackthorn", "tonic water", 1.5, 1.0, "pineapple juice", "mix with ice").
("Blue Moon", "soda", 1.5 "Blueberry Juice",. 75, "mix with ice, strain")
;

I ended up doing just individual INSERT statements, which was not as convenient.
INSERT INTO HF_easy_drinks
VALUES ('Blackthorn', 'tonic water', 1.5, 1.0, "pineapple juice", "mix with ice");
INSERT INTO HF_easy_drinks
VALUES ('Blue Moon', 'soda', 1.5, 'Blueberry Juice',. 75, "mix with ice");

Hello

Perhaps you might prefer "an" insert like this:

INSERT INTO hf_easy_drinks (x, y, z,...)
SELECT "Blackthorn", "tonic water", 1.5, 1.0, "pineapple juice", "mix with ice" OF THE double
UNION ALL SELECT 'Blue Moon', 'soda', 1.5, 'Blueberry Juice',. 75, "mix with ice, strain ' FROM dual
SELECT UNION ALL... OF the double
SELECT UNION ALL... OF the double
;

Need help with the insert statement

Hello

I have a question on how to write a SQL statement.

This is the table of "base":

CREATE TABLE TEMP_TBL
(
id_nr NUMBER,
DATE_DOK DATE,
DATE_DUE DATE,
DATE_DOK_PAY DATE,
DEB NUMBER,
KRD NUMBER
);

insert into temp_tbl (ID_NR,DATE_DOK,DATE_DUE,DATE_DOK_PAY,DEB,KRD)values('1',TO_DATE('11.01.2011','DD.MM.YYYY'),TO_DATE('25.02.2011','DD.MM.YYYY'),NULL,'423,24','0');
insert into temp_tbl(ID_NR,DATE_DOK,DATE_DUE,DATE_DOK_PAY,DEB,KRD)values('2',TO_DATE('16.12.2011','DD.MM.YYYY'),TO_DATE('13.06.2011','DD.MM.YYYY'),NULL,'91270,15','0');
insert into temp_tbl(ID_NR,DATE_DOK,DATE_DUE,DATE_DOK_PAY,DEB,KRD)values('3',TO_DATE('27.09.2011','DD.MM.YYYY'),TO_DATE('27.09.2011','DD.MM.YYYY'),NULL,'0','2000');

and it comes to resoult in the target table. SQL statement must take care of the insert in a base of the target table table (example below is already provided with test data).

create table table_sod
(

      id_nr number
     ,date_from date
     ,date_to date
     ,deb_krd number

);

One thing to note here :  values in column deb_krd under insert 1 and 4 must be summarized in insert 4.

insert into table_sod (id_nr,date_from,date_to,deb_krd) values('1',null,to_date('25.02.2011','dd.mm.yyyy'),'423,24');
insert into table_sod(id_nr,date_from,date_to,deb_krd) values('2',to_date('26.02.2011','dd.mm.yyyy'),to_date('13.06.2011','dd.mm.yyyy'),'423,24');
insert into table_sod(id_nr,date_from,date_to,deb_krd)values('3',null,to_date('13.06.2011','dd.mm.yyyy'),'91270,15');
insert into table_sod(id_nr,date_from,date_to,deb_krd)values('4',to_date('14.06.2011','dd.mm.yyyy')to_date('27.09.2011','dd.mm.yyyy'),'91693,39');
insert into table_sod(id_nr,date_from,date_to,deb_krd)values('5',null,to_date('27.09.2011','dd.mm.yyyy'),'2000');

If someone could give me a helping hand how write correct insert statement I would be really gratefull.

Help with the insert statement
Hello

I was wondering if someone could help write me a sql statement.

Here is my table:
```
CREATE TABLE "TEMP_INVOICE" 
   ("INVOICE" VARCHAR2(100 BYTE),
     "DATE_OF_DOCUMENT" DATE, 
     "DATE_OF_PAY_DAY" DATE, 
     "D" NUMBER, 
     "K" NUMBER
   );
```
Here are the instructions for correct insertion. This time, I posted 2 examples with 2 numbers different otherwise.
```
insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.02.2012','dd.mm.yyyy'),to_date('01.03.2012','dd.mm.yyyy'),5000,0);
 
insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.04.2012','dd.mm.yyyy'),'','',1000);
 
insert into temp_invoice (invoice,DATE_OF_DOCUMENT,DATE_OF_PAY_DAY,d,k)  values (1000,to_date('01.05.2012','dd.mm.yyyy'),'','',3000);

```
I want to do is make an insert allows you to table another call is MADE:
```
CREATE TABLE "INVOICE" 
   ("INVOICE" VARCHAR2(100 BYTE),
    "DATE_OF_DOCUMENT" DATE, 
     "DATE_OF_PAY_DAY" DATE,
     "DATE_OF_PAYMENT_REC" DATE,
     "VALUE" NUMBER,
     "VALUE_DEDUCT" NUMBER,
    "DATE_FROM" DATE,     
     "DATE_TO" DATE
     );
```
Statements in the INVOICE table should be like this:

........ The Bill... date_of_document... date_of_pay_day... date_of_payment_rec... value... value_deduct... Date_from... Date_to
1......     1000...............1.1.2012.................1.3.2012................NULL............................ 5000... NULL... 1.3.2012...1.4.2012
2......     1000...............1.4.2012.................NULL..................... 1.4.2012...1000... 4000... 2.4.2012... 1.5.2012
3......     1000...............1.5.2012.................NULL..................... 1.5.2012...3000... 1000... 2.5.2012... 1.6.2012
4......     1000...............1.6.2012.................NULL..................... 1.6.2012...1000

Can someone help me with the sql statement that would insert data from table to table Bill temp_invoice as in the example?

Thank you!

PS

I would try to explain.
(1) the first statement that is to be inserted is original imply that at which is different DATE_OF_PAY_DAY to NULL.
To this inserted negative of the original imply, we must add date_from that is exatly the same date_of_pay_day and date_to which is exactly the same as the date of the first payment. Payment which came first!
(2) we have now in the second insert statement. It will be the first payment of lease with date_of_document and date_pf_payment_rec, which is the same as date_fo_document. Value field will be populated with the amount of payment received and value_deduct field will be the value of the original imply - value of the first payment. Date is date_of_document + 1 and date_to is the date of the next payment.
(3) Insert us the next installment. Date_od_payment_rec is the same as date_of_document... value is the amount of the second payment and value_deduct's previous value_deduct which was of 4000 - value of this second payment. date_from date_of_payment_rec + 1 and date_to is the date of the next payment

So we continue this same pattern until we reached the final payment when we finish insert with the statement:
Date of the document (date of the last payment received) and even for date_of_payment_rec and field value with the amount of the payment receieved. The rest (value_deduct, date_from, date_to) is null.

I really hope you understand what I'm trying to do here.

If you have any other questions please.

Ok!
Be sure to post the results you want new data.

You probably need to add "PARTITION BY the Bill" to all analytical clauses in my solution:
```
INSERT INTO invoice
( invoice, date_of_document, date_of_pay_day, date_of_payment_rec
, value,   value_deduct,     date_from,           date_to
)
SELECT       invoice

,       date_of_pay_day
,       CASE
           WHEN  k > 0
           THEN  date_of_document
       END          AS date_of_payment_rec
,       NVL (d, k)     AS value
,       NVL2 ( date_of_pay_day
            , NULL
            , SUM (d) OVER ( PARTITION BY  invoice
                                      ORDER BY      date_of_document
                     )
            - SUM (k) OVER ( PARTITION BY  invoice
                                      ORDER BY      date_of_document
                     )
            )     AS value_deduct
,       NVL ( date_of_pay_day
           , date_of_document + 1
           )          AS date_from
,       LEAD (date_of_document) OVER ( PARTITION BY  invoice
                                        ORDER BY      date_of_document
                           )
                      AS date_to
FROM       temp_invoice
;
```
Because I'm not an English speaker nativ, that I just posted what it should look like after the insert is successful.

OK, so you can't explain as you want, but you still need to explain.

... @Frank Kulash: you are very close, but still not quite what I'm looking for.

Point out where my solution is the production of incorrect results, and explain (as you can) how to get good results in these places.

On the insert statement
Hi all

I need to insert rows into a table, all the columns are have same value except a column that is to say

insert into table values ('a', 'b', 'b', 'b');

insert into table values ('b', 'b', 'b', 'b');

Insert in the table values ('b', 'b', 'c', 'b');

y at - there no shortcut for insert because there are thousands of records to insert

Help, please

Thank you
If data are available in another table, you can use a select statement inside your insert statement.

Incomplete example
```
NSERT INTO TABLE (
  COL1,
  COL2,
  COL3,
  COL4

)
SELECT FROM OTHERTABLE WHERE...,
'b'
'b'
'b'
...
```
The doc show this as an example:
```
INSERT INTO AIRPORTS (AIRPORT, CITY, COUNTRY)
  SELECT AIRPORT, CITY_NAME, COUNTRY FROM CITIES
  ORDER BY AIRPORT;
```
SELECT yourvalue, 'b', 'b', 'b' of...

As an academic exercise, I wanted to rewrite the above statement without using the WITH clause, I tried this (amongst dozens of other tests - I hit a mental block and cannot understand):

prompt
prompt without with

       c.flag,

       -- This is what I've tried as the equivalent statement but, it is
       -- syntactically incorrect.  What's the correct syntax for what this
       -- statement is intended ?
       --
       (
        select sum(t2.flag)
          from c t2
         where t2.proj_end <= c.proj_end
       ) as proj_grp
  from (
        select a.proj_id,

               a.proj_end,
               case when (

Thanks for the help, much appreciated.

value of the check box in the insert statement
I'm hand-coding an insert from the insert record sb construction will do for this application. The values of several form elements are inserted into the fields in the table. The problem that occur is a checkbox value in the form. If the box is checked, all is well and the value is 'True' inserted in the appropriate database field. However, if the checkbox is not checked I get syntax error message. The reason being that, while are passed on to the fields with null null, the checkbox is not transmitted at all. This is evident when changing the method of the form to 'Get' for testing purposes. There is no reference to this field check box in the query string.

My assumption is that this would require an If statement changing the value of the 'False' check box when the box is blocked. How I would go to this topic. With my knowledge limited to the ASP, I wrote the following, but it doesn't seem to work:

< input name = "emailprob_mor" type = "checkbox" id = "emailprob_mor" value = "< % If Not (IsNull (Request.Form ("emailprob_cus")) then Response.Write"True") Else Response.Write ("False") End If % >" >
When you use the boxes, it is better to separate your Request.Form statement and your insert statement:

cbVal = '0 '.
If (Request.Form ("emailprob_mor") <> "") then cbVal = Request.Form ("emailprob_mor")

Then in your SQL statement:

"& cbVal &"..."

For your real HTML:

"" ) then response.write(" checked='checked' ") %>>

It is true that if the user does not check the box, then it appears as if there is no when it is submitted, that is the reason why he must be given a default value when the record is inserted.

High logical reads with the INSERT statement
Hello

I have an INSERT query that is having a very high reading statspack logical reads. I've seen go Asktom announcement that this is due to the index. Link: [http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6643159615303]

Can you please help to explain exactly what Oracle do and why you should read so the e/s logic. It's the that oracle must read the structure of the index for all (bundle branch block + all blocks of sheet) for each insertion line?

Thanks & appreciate the insight.

Only 5 bound for first INSERTION and only 1 for the next INSERTION.

This is false.

"db block ' is ALSO to the e/s logic." This is gets them in CURRENT mode. Oracle reads the Index blocks in the current mode to update the index blocks.

Your last statement is in direct contradiction with the previous paragraph

As Tom mentioned, oracle must change the index as well when records are inserted in > (or updated or deleted from) the table. This means oracle must first read the index blocks (in > compatibility mode (LIO) as well as in current mode) in addition to the blocks of the turntable when inserting new > records. So this must explain why LIOs are more when inserting in an indexed table from > inserting into a table not indexed.

What is correct.
