Want to construct insert statement from all_tab_columns

I am using Oracle 10GR2 and a new user for plsql
I want to write a plsql block or SQL in order to insert some dummy data.
I want to use the column list from all_tab_columns and want to construct insert statement
EX: I am trying to construct SQL as below
for i in (select column_name from all_tab_columns where table_name='EMP')
loop
v_sql := insert into emptest valuesi.column_name
could you please let me know any pointer for the same ..?
can I use any other technique for the same .. like collection, nested table etc

Am not clear for this requirement, if possible could you please elaborate.
Also specify the requirement, inputs and expected outputs with your query in code format...
This will help..

Create multiple Insert statements from multiselect list

I want to thank everyone in advance for the help on this one.
I have a multiselect list that I would like to use to create multiple Insert statements. I would like to then take those statements and execute them against the database, thus inserting the records. My thoughts are below;
1.     Customer selects multiple items in the list
2.     Clicks the submit button
3.     onclick event walks through the string created by the multiselect list and creates the Insert statements by walking through an array of the values.
4.     the Insert statements get executed against the database
5.     page redirects to the proper page after the process is done.
I actually have already created a javascript function that will use the split command on the string to create an array. I then get the length of the array and walk through a loop creating the sql statements. I am not sure what to do from here. How can I get the sql to execute.
I am not wed to this approach. If there is a better idea out there please do not hesitate to share it with me. I am relatively new to APEX and have not done much work in pl/sql or javascript. But I learn fast, so don’t hold back.
Thanks again and please let me know what questions you have for me.
Derek.

I setup the demo app on apex.oracle.com:
http://apex.oracle.com/pls/apex/f?p=26255:3
Login as demo / demo
Go to the "products" tab. There is a Test region with a multiselect list. It shows product names (with product id's) from the demo_product_info table.
When you select multiple things from the list and click apply, it uses the following procedure to simply insert a new record for each into the product table. It increments the product_id by 1000 and prepends "DUPLICATE " to the product_name:
declare
cursor c_products is
select product_name, product_id
from demo_product_info
where instr(':' || :P3_X || ':', ':' || product_id || ':') >= 1
order by 1
begin
for r_product in c_products loop
insert into demo_product_info (product_id, product_name)
values (r_product.product_id + 1000, 'DUPLICATE ' || r_product.product_name);
end loop;
end;
You can see that is working by using it on the duplicate entries themselves.

How to change Bulk Insert statement from MS SQL to Oracle

Hi All,
Good day, I would like to bulk insert the content of a file into Oracle db. May I know how to change the below MS SQL syntax to Oracle syntax?
Statement statement = objConnection.createStatement();
statement.execute("BULK INSERT [TBL_MERCHANT] FROM '" MERCHANT_FILE_DIR "' WITH ( FIELDTERMINATOR = '~~', ROWTERMINATOR = '##' )");
Thanks in advance.

How to prepare an INSERT statement from the resultset

Hi Friends ,
I have to generate CREATE and INSERT statements for the Table already present in the database .
I can prepare CREATE statement by getting the MetaData from the database . Is it possible to create INSERT statement for the data already present in the database table if so how.
Thanks ,
Rajesh Reddy

You should be able to do something like SELECT * FROM foo WHERE 1 = 2. No rows will be returned. Call ResultSet#getMetaData() to get the meta data for the column names and types. You should then be able to dynamically create your own INSERT statement.

Generate Insert Statement Script to Extract Data from Table in Oracle 7i

Hi all, I have an old Oracle legacy system that is running for over 15 years.Every now and then we need to extract data from this table@ ORacle 7i to be imported back to Oracle 10G.
My thoughts are to create a script of Insert statements in oracle 7 and that to be deployed back to Oracle 10G.
I found this scripts in Google and not sure how exactly this works.Any explanation on thsi scripts , would be greatly appreciated.I find this scripst may help to generate a set of insert statements from that table to the latest table at 10G.

Insert statement executes before If statements

Hello All,
I am trying to validate few fields before inserting them into table.
for example:
IF params('txtID') IS NULL THEN
"SOME MSG";
ELSIF params('txtName') IS NULL THEN
"SOME MSG";
END IF;
INSERT INTO TABLE T1
VALUES(params('txtID'),params('txtName');
What I want to do is : I want to validate two fields before inserting.
Can anyone help me?
Thank you,
H.

It directly executes insert statement. If I delete insert, it executes that IF statement.
It is strange.Let's be clear about this, it is not strange. Your original IF statements did execute before the INSERT but they did not raise an exception. Consequently the INSERT statement was processed. Your "SOME MSG" mechanism is obviously only triggered after the procedure completed. Walter's solution worked for you because it raise exceptions, which prevented the INSERT statement from executing.
Anyway, it is obvious that you haven't got NOT NULL enforced on your table, which is A Bad Thing. You shoudn't be enforcing such constraints through a procedure.

How to assign value from insert statement to variable from a trigger

Hi,
I got this really annoying problem and I don't know if I am doing it correctly.
I have a BEFORE INSERT trigger on a table. When someone executes an insert statement I want to grab the value of a column from that statement and assign it to a variable and then do stuff with it. I'm stuck on the assignment.. look below..
CREATE OR REPLACE TRIGGER CARS.geotest2_trigger
BEFORE INSERT ON CARS.GEO_TEST2
FOR EACH ROW
DECLARE
v_chainkey nchar(32);
v_chainkey2 nchar(32);
not_exists EXCEPTION;
BEGIN
:NEW.CHAINKEY := v_chainkey;
SELECT GEO_TEST.CHAINKEY INTO v_chainkey2 FROM GEO_TEST WHERE GEO_TEST.CHAINKEY = v_chainkey;
IF v_chainkey2 = '' or v_chainkey2 is null THEN
RAISE not_exists;
ELSE
INSERT INTO GEO_TEST2 VALUES(:NEW.CHAINKEY, :NEW.BLA, :NEW.FOO);
END IF;
EXCEPTION
WHEN not_exists THEN
RAISE_APPLICATION_ERROR(-20010, 'Chainkey does not exist in parent table GEO_TEST');
END;
I keep getting this error
Error: ORA-04098: trigger 'CARS.GEOTEST2_TRIGGER' is invalid and failed re-validation
SQLState: 42000
ErrorCode: 4098

It isn't assigning because v_chainkey is not at the left hand side of the assignment statement.

I think the sole purpose of that "not_exists" exception is this -
If you try to insert a NULL value for GEO_TEST2.CHAINKEY, then this trigger will throw an error even if at least one NULL value exists in GEO_TEST.CHAINKEY column.
Not sure if that's something that you wanted.

Question on Creating Table From Insert statement

Hi,
I want to create a table using a DBlink from another database using the create/insert statement. Will it also transfer the constraints or do I have to do it manually afterwards? Thanks.
Create table T1
SELECT a,b,c from T2 from DB@dblink;

As discussed above, the constraints, indexes, triggers are not copied. Only NOT NULL constraints are copied.
Look at this thread Re: Copying table structure.
for copying triggers/indexes from source table to destination table.
Thanks,

I want to change screenshot location from my Solid State hard drive with OSX on it, to my 2nd storage hard drive, how do I do this?
I am aware of "defaults write com.apple.screencapture *location*" but I want to change the location to my 2nd drive which doesn't have OSX on it... everytime I've tried to insert MacintoshHD2 in there it just doesn't work... any tips?

I'm having the same problem. I've entered the following path in terminal:
"defaults write.com.apple.screencapture location /Volumes/Macintosh HD 2/[my username]/Downloads"
But it's not working. It keeps going to the SSD Downloads folder.

Insert records from a single table to two related tables

DB - 10G
OS - XP
We have many thousands of comma delimited records that we want to insert into a normalised table structure.
I have created a test dataset that can be found at the end of this post.
I have csv records that look like this;
donald, huey
donald, dewey
donald, louie
And I want the data to be inserted into two separate table like this;
table named PARENTS
pk parent_name
1 donald
Table named CHILDRENS
pk fk child_name
1 1 huey
1 2 dewey
1 3 louie
I constructed an insert statement that looks like this;
INSERT ALL
INTO parents (parent_id, parent_name) VALUES (parents_seq.nextval, parent_name)
INTO children (children_id, parent_id, child_name) VALUES(children_seq.nextval, parents_seq.nextval, child_name )
SELECT parent_name, child_name
FROM sources;
And this resulted in the following;
Table named PARENTS
pk child_name
1 DONALD
2 DONALD
3 DONALD
Table named PARENTS
pk fk child_name
1 1 HUEY
2 2 DEWEY
3 3 LOUIE
Would anyone have any ideas on how I could accomplish this task?

table_name = 'PS_D_RE_BCSREGIONMAPPING';
   v_sql:='insert into tablename (' ;
     for i in 1..arr(col_count)
      loop
       v_sql:='v_sql' ||' '||arr(i);
      DBMS_OUTPUT.PUT_lINE(v_sql);
     END LOOP;
END;

Below is the actual code which i am trying to write:
Since the below trigger logic is same for around 25/30 tables i wanted to construct a generic procedure which will take input parameter as tablename and auit_table and form the insert statement which will populate the column names which are different for different tables.
Please guide...
CREATE OR REPLACE PROCEDURE make_trigger( tablename in VARCHAR2,
                                         auditable in   VARCHAR2
AS
v_sql varchar(10000);
begin
v_sql := 'DROP TRIGGER TRD_D_AUDIT_D'||tablename;
dbms_output.put_line (v_sql );
v_sql:='CREATE OR REPLACE TRIGGER TRG_D_AUDIT_D_'||tablename||' '||
'BEFORE INSERT OR UPDATE OR DELETE ON 'tablename||' '||' REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW';
dbms_output.put_line (v_sql );
v_sql:= 'DISABLE
DECLARE
v_Operator        psoprdefn.oprid%type;
v_Sysdate        Date;
v_Actn            varchar2(1);
V_AUDIT_RECNAME    PSRECDEFN.RECNAME%type;
BEGIN';
dbms_output.put_line (v_sql );
v_sql:= 'If (Inserting) Then
   v_Actn    :='||'''||'A'||'''||';'||
   'Insert into '||auditable||'
                    ('||
                   AUDIT_RECNAME,
                AUDIT_ACTN,
                AUDIT_OPRID,
                AUDIT_STAMP,
                D_USER_GROUP,
                D_GROUP_DESC,
                D_BCS_ID,
                D_UBR_ID,
                D_FILTER_ID,
                D_NAME_ACCESS_TYPE,
                D_GLOBAL_EMP_LIST
                    Values
                V_AUDIT_RECNAME,
                v_Actn,
                v_Operator,
                v_Sysdate,
                :NEW.D_USER_GROUP,
                :NEW.D_GROUP_DESC,
                :NEW.D_BCS_ID,
                :NEW.D_UBR_ID,
                :NEW.D_FILTER_ID,
                :NEW.D_NAME_ACCESS_TYPE,
                :NEW.D_GLOBAL_EMP_LIST
end if;
