CREATE SEQUENCE in jsp

Dear all
i have one question would like to ask someone who can help that .
if when i create one table with sequence in that table when i want to add any value use jsp script how can i declare sequence data type?
for example
in sql command line = INSERT INTO test VALUES( some_sequence.nextval
and how can i defind some_sequence.nextval in jsp page ?
what should i use ? string or int

Yes, it's possible to create classes inside JSP files.
<%!
class Whatever {
   String variable = "java";
   void doSomething() {
      // Doing nothing :) ...

Oracle sequence from JSP

Hi,
I have to generate sequence numbers in Oracle and access it through my JSP page. For that i
created a sequnce in Oracle as:
create sequence trans_no increment by 1 start with 1 maxvalue 10000 minvalue 1;
and in my JSP page, the following code is given:
ResultSet resultSet=db.executeQuery("select trans_no.nextval from dual");
resultSet.next();
int transaction_no=resultSet.getInt("trans_no");
where db is my bean. But it is giving error. Is my code wrong? Please help.
Suman, Kochi

There is a mistake in mapping for ResultSet with the query you executed.
You have to modify either the query as
ResultSet resultSet=db.executeQuery("select trans_no trans_no.nextval from dual");
or have to change retreival from ResultSet to
int transaction_no=resultSet.getInt(1);
This should work now.
Try this and see...

CREATE SEQUENCE from a stored procedure

Hello,
Is it possible, to create a sequence object from an own written stored procedure? Can I reinitialize the actual value of a sequence object without recreating it from a stored procedure?
Thank you for recommendations,

Oracle doesn't like the "(select max(bulletin_master_id)+1 from bl_btn_master)' statement embedded in the CREATE SEQUENCE statement because if you look at the syntax it is expecting an acual number. You could use execute immediate to create the sequence this way:
{code}
declare
v_seq number;
v_statement varchar2(200);
begin
select max(bulletin_master_id)+1
into v_seq
from bl_btn_master;
v_statement := 'CREATE SEQUENCE BL_BTN_MASTER_SEQ ' ||
'MINVALUE 1 ' ||
'MAXVALUE 999999999999999999 ' ||
'INCREMENT BY 1 ' ||
'START WITH ' || v_seq ||
'NOCACHE';
execute immediate(v_statement);
end;
{code}

Assigning a 'dynamically created sequence' value to a variable

in my procedure i am creating a sequence on the fly, i am preparing the name with some passed parameters like below
v_seq_name := 'seq_'||loadid||v_table_name;
execute immediate 'CREATE SEQUENCE '||v_seq_name||' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment by 1 cache 20';
and now after doing some operations i need to assign the current value of sequence to a number variable i tried following but not working
1) v_curr_value : = v_seq_name.currval ;
2) select v_seq_name||'.nextval' into v_curr_value from dual;
can you please suggest me how i can get the value in plsql block.

Having said that, your architecture is probably wrong if you are dynamically creating things in a procedure.
Why do you need to create them dynamically?

Issue in creating a new JSP in Quoting

I have created a new JSP in the quoting. That JSP is displaying the data properly but the cue card menu is not visible in that JSP. Is there any mapping need to be done to make it visble.

Thank you for the response.
The JSP has a function defined in the menu structure. For a trial I copied an existing jsp into another and called the copied one. the side menu bar did not get displayed, but the content got displayed.
Can you please tell me, if we create a new JSP page how many mappings need to done and what are they.

Creating sequences for all tables in the database at a time

Hi ,
I need to create sequences for all the tables in my database.
i can create individually ,using toad and sqlplus.
Can any one give me a code for creating the sequences dynamically at a time for all the tables.
it is urgent ..
Regards.

I need to create sequences for majority of the tables that are having ID column
which is sequences."The majority" is not the same as all. So you probably want to drive your generation script off the ALL_TAB_COLUMNS view...
where column_name = 'ID'You need to think about this carefully. You might want different CACHE sizes or different INCREMENT BY clauses for certain tables. You might even (whisper it) want a sequence to be shared by more than one table.
Code generation is a useful technique, but it is a rare application where one case fits all.
Cheers, APC

How to CREATE SEQUENCE in one table

dear all
the one thing i want to know when i use CREATE SEQUENCE in one table like this and then at that table
CREATE SEQUENCE oproduct_sequence
START WITH 1 INCREMENT BY 1
nocache
create table oproduct(
tname varchar2(20) not null,
tid int default oproduct_sequence.nextval
the system indicat that i cannot use this way to create table , so i really want to know how can i achieve this method
becuase when i want to insert inot table oproduct only use
insert into oproduct valuse('aaaa');
and the result like
aaaaa 1
bbbb 2

Actual name is before insert trigger. Some examples are listed below:
Example Number 1 ...
create sequence product_seq start with 1 increment 1
create or replace trigger product_insert before insert for each row begin
select productseq.nextval
into :new.product_id
from dual;
end;
Example Number 2 ...
How to create an autoincrement field in a table with a sequence ...
SQLWKS> create table bob(a number , b varchar2(21));
Statement processed.
First create a sequence
SQLWKS> create sequence x ;
Statement processed.
Then create the trigger.
create trigger y before insert on bob
for each row
when (new.a is null)
begin
select x.nextval into :new.a from dual;
end;
Example Number 3 ...
First create a sequence:
create sequence emp_no_seq;By default it increments by 1 starting at 0.
Use its values when inserting data into the table:
insert into t_emp values (emp_no_seq.nexval, 'Joe Black');~ Madrid.

I also join the other folks that have tried to help you in suggesting that creating a sequence dynamically in a procedure is a very poor idea and almost certainly indicates that you need to reconsider your design.

Create sequence, function and view all at once -script or something similar

Hi I would like to know in what way can I write a script or something like that which would define names for a sequence, function and a view in the beginning (for example TEST_SEQ, TEST_FJ, TEST_VIEW...) and after that create this sequence, function and view with definitions like
CREATE SEQUENCE TEST_SEQ
MINVALUE 1 MAXVALUE 999999999999999999999999999
INCREMENT BY 1 START WITH 1 NOCACHE NOORDER NOCYCLE;
create or replace FUNCTION TEST_FJ RETURN NUMBER AS
tmp number;
BEGIN
select TEST_SEQ.NEXTVAL into tmp from dual
RETURN tmp;
END TEST_FJ;
and so on...
In the end I would also like to grant some rights on these objects I just created:
grant select on TEST_SEQ to public;
grant execute on TEST_FJ to public;
So my question is how to package all these things together so I can execute them from a single file in SQL Developer, and if i need to change the names of these tables I want do it in one place in the beginning of this script (or something like a script, I'm not sure what)...
Thanks in advance!

hi,
hope help you...
this is my basic generic solution...
create or replace procedure createSequence( psequenceName in varchar2 ) is
begin
execute immediate 'create sequence ' || psequenceName ;
execute immediate 'grant select on ' || psequenceName || ' to public ';
end ;
create or replace function getNextVal( psequenceName in varchar2 ) return number is
queryText varchar2(100) := 'select <sequence_name>.nextval into :next_value from DUAL' ;
next_value number ;
begin
queryText := replace(queryText,'<sequence_name>',psequenceName);
execute immediate queryText into next_value ;
return( next_value ) ;
end ;

Cannot use sqlplus variable in create sequence statement

Hello!
I would like to create a sequence object starting with a number retrieved from a select statement:
var max_resp_no number;
begin
select max(substr(resp_no,2)) into :max_resp_no from brc_mast
where substr(resp_no,1,1)='Z';
end;
print max_resp_no;
drop sequence p659_resp;
create sequence p659_resp start with :max_resp_no;
It tells me that :max_resp_no is an 'invalid number';
TIA,
habeeb

You need to do this entirely in PL/SQL. You can either create a procedure, or use an anonymous block. The procedure version is below. Just change the CREATE to a DECLARE to get an anonymous block.
CREATE OR REPLACE PROCEDURE new_seq IS
max_resp_no NUMBER;
BEGIN
SELECT to_number(MAX(SUBSTR(resp_no,2)))
INTO max_resp_no
FROM brc_mast
WHERE SUBSTR(resp_no,1,1)='Z';
EXECUTE IMMEDIATE 'DROP SEQUENCE p659_resp';
EXECUTE IMMEDIATE 'CREATE SEQUENCE p659_resp START WITH '|| max_resp_no;
END;
SQL> CREATE SEQUENCE p659_resp START WITH 1;
Sequence created.
SQL> SELECT p659_resp.nextval from dual;
   NEXTVAL
         1
SQL> SELECT * FROM brc_mast;
RESP_
Z001
Z002
Z003
Z075
SQL> exec new_seq;
PL/SQL procedure successfully completed.
SQL> select p659_resp.nextval from dual;
   NEXTVAL
        75Note that the user creating this procedure will need to have CREATE SEQUENCE granted explicitly for the procedure to work. The anonymous block version should work if CREATE SEQUENCE is granted through a role.

How to create sequence when minvalue is unknown?

I am currently migrating a lot of tables (that already have data) over to using sequences. I'd like to have a script that creates these sequences without having to hardcode the minimum value that the sequence should start at.
I am trying to do something like this:
create sequence mySeq minvalue (select max(id)+1 from table) increment BY 1 cache 20;
This always gives the error "Invalid number". Can anyone provide some guidance on how to solve this problem?

Like this..?
SQL> declare
2   min_val number;
3   str varchar2(1000);
4 begin
5   select nvl(max(empno),0)+1
6   into min_val
7   from emp;
8   str := 'create sequence seq1 start with '||min_val||' increment by 1 cache 20';
9   execute immediate str;
10 end;

How to create sequence

How to create sequence(Auto generated no in oralce) with out using Triggers?
If i create trigger sequence of numbers are getting generated but in case if i want to include explicit sequence no at the end of the table say like '9999'...it is not getting updated
Pls help very urgent..

user2134711 wrote:
How to create sequence(Auto generated no in oralce) with out using Triggers? Sequence is an oracle object used to create unique number sequence. It has no connection with trigger.
Generally Sequence is used in a Trigger to generate some column value automatically. Something like the IDENTITY column used in SQL Server.
If i create trigger sequence of numbers are getting generated but in case if i want to include explicit sequence no at the end of the table say like '9999'...it is not getting updated This totally depends on how you have written the trigger. If you can show your trigger code we can help you out.
