Hi Guyz,

I have written the sequence code on the below trigger for generating sequence number

Trigger Name : Pre - Insert

select myseq.nextval into :vendor.vendor_id
rom vendor;

is there anyway to generate these number manually? i want to generate the sequences on when button pressed?


Regards

Is it a tricky question?

Because, it looks quite obvious - create a push button item, create a WHEN-BUTTON-PRESSED trigger and select next sequence value.

Ooops! Could you, please, share the code you use? Possibly, copy and paste SQL*Plus session which looks like this:
SQL> select 'x' from dual;

'
-
x

SQL>

Because, if someone has dropped the DUAL table, I'm afraid that you are in very, very ... very deep sh*t (trouble, I mean).

RD,

Fascinating observation. Does this mean that you have solved your problem or have not solved your problem?

Have you signed on to the database?

Is this your first form? Have you run the 'test' form?

Yes, I have signed on to the Database. The form was running well before I added this functionality.

I have a created a form which is is based on a database of books. Here, the user gets to add books while running the form (dynamically). However, I would like the serial no of each record to get updated i.e. whenever a new record (book details) is inserted, the sr_no should be automatically generated in the database.

I have given a Pre-Insert Trigger at block level as follows:

select bookno_seq.nextval into :books.sr_no from dual;

However, I am getting these errors

"Error 201...........identifier 'dual' must be declared"

"Error 0..............SQL statement ignored"

thank you

At the bottom of the Oracle Forms Builder, Object Navigator there is Database Objects, click on the '+' sign, then click the '+' sign on 'SYS', then click the '+' sign on 'Tables'. Can you see 'dual' in the list (between 'dir$victim_policy' and 'duc$')?

Hi David,

I can see the dual table. It's placed between 'AW$EXPRESS' and 'ODCI_SECOBJ$'

thank you

Before going on, would you, please, mind to execute the following query (connected as a privileged user (SYS)); the result should be as displayed:
SQL> col owner format a15
SQL> col synonym_name format a15
SQL> col table_owner format a15
SQL> col table_name format a15
SQL> col db_link format a10
SQL>
SQL> select * from all_synonyms where synonym_name = 'DUAL';

OWNER           SYNONYM_NAME    TABLE_OWNER     TABLE_NAME      DB_LINK
--------------- --------------- --------------- --------------- ----------
PUBLIC          DUAL            SYS             DUAL

SQL>

If query returns nothing, try the following:
SQL> create public synonym dual for sys.dual;
Go back to the form, remove "sys." from the query and try to compile the trigger again.

Because, it sounds as if someone has dropped the public synonym (but, as GRANT has remained, you were able to use DUAL when you have specified owner (as "sys.dual")).

However, if that's not the case, nothing else comes on my mind at the moment.
