Using sequence in a procedure

I understand that oracle doesnt allow you to use for example, sequence_name.NextVal in a procedure when adding data.
Is there any other ways round this? It would be great if someone could give an example as im a beginner with Oracle.
Thanks

just to confirm...

USING SEQUENCE IN PACKAGE SPEC

I Want to Use Sequence.NEXTVAL & Sequence.CURRVAL throughout the package. How can i declare the global sequence variable and make them available for all the stored procedures inside the package ?
Any help highly appreciated..
Thank you all in advance

Data Boy wrote:
No i know that but using directly SEQUENCE.CURRVAL inside the Insert statement is not a good practice.
We need to declare inside the procedure a variable and then fetch the SEQUENCE.CURRVAL into that variable
and use that variable inside the insert statement. But we that variable scope will be available only inside that procedure.
if i want the same CURRVAL in another stored procedure. How can i get it ..that is my Question.What exactly are you trying to achieve?
If it's a case of needing to know the value of the sequence number assigned to an inserted record you would typically use the RETURNING clause on the insert statement...

How do I alter a sequence in a procedure

I need to alter sequences in a procedure. I have done this before on an Oracle 8 database using:
EXECUTE IMMEDIATE ('ALTER SEQUENCE OFFICIAL_ID_SEQ INCREMENT BY ' ||( v_official_id_high - v_official_id_current));
How do I do this on an Oracle 7 database?
Thanks,
Alison.

You will have to use dbms_sql to do that

Tax calculation in CRM using R/3 pricing procedure

Hello Experts
We are using R/3 pricing procedure to calculate list prices in CRM.
The condition record for Taxes are maintained for condition type UTXJ in SD which is calling for tax procedure TAXUSJ and condition type JR1.
The records are maintained in FTXP. This is the SAP Standard way of maintaining taxes if external tax software is not used.
We have downloaded the condition records and condition types in CRM. The tables have all the required records downloaded from R/3.
When creating an order in Webshop the tax is not getting calculated.
The pricing analysis shows that the condition record for UTXJ condtion type is met, but it is not showing the tax maintained for condition type JR1.
Have we missed any settings here?
If we are using R/3 billling does the TTE needs to be activated for calculating taxes in the webshop?
If TTE needed to be used for calculating taxes, what are the settings needed to be configured?
Thanks in advance for the valuable advice.
Sastri

Hi Sastri,
I am facing this problem with TAX Condition Records: Pricing error: Mandatory condition MWST is missing. I am using a R/3 pricing procedure correctly downloaded to CRM.
You say that you have downloaded the condition records and condition types in CRM. SAP Library says 'Prerrequisites: You have downloaded the tax condition records from SAP ECC'.
I don't know If my problem is caused because I haven't downloaded any Tax Condition Records. The fact is that I cannot determine which one is the Condition Object to download in R3AS.
I would really appreciate if you or anyone could tell me which object you did use.
thanks in advance,
Pablo

How to use Sequence in Forms

Hi,
I have an Empno Column, At the time of Opening a Form The Empno Will be displayed by using Sequence.
If the User doesn't save the Form Then the Empno Generated number will be changed.
How to write the code to get sequence numbers at Empno columns by using Sequence?
Thanks & Regards,
Hari Babu

Ok, I understand now your question. Since the oracle sequence is commited in a separate transaction, it is not possible to get the no-gap sequence, considering your example. In the other hand, if you don't commit immediately, than two concurrently opened forms could use the same sequence number, so you'll get the duplicate key!
If you're sure that this couldn't happen, you can manage your own sequencing, storing them in another table. Let's say you reached seq 999: entering the form, you'll read from your sequence table 1000, increment to 1001, and assign it to empno, but without commiting. Next time, you'll get the same number, until you commit form, and at the same time, change in seq table. So another will get 1001.
Downside of this approach are, as mentioned before, concurrent sessions, which will get the same sequence.

Comenting code - style - how to keep coments where you want them - without using sequences

Silly question maybe about style of commenting.
Basically i like to use sequence boxes to keep comments on my diagram beside the bits of code that they refere to - otherwise when you use diagram cleanup (which i'm afraid i use all the time) they go anywhere. This is good - except that i found especially when doing FPGA programming the sequence boxes reduce the amount of parralelism that can go on - since the 'box' needs to finish before any of the outputs can be used. Is there some other method i should be using instead of sequence boxes to keep text beside elements - without enforcing that a set of elements are fixed in one place?
Solved!
Go to Solution.

I usually use labels of structures (loops, cases, etc) and labels of diagram constants, etc. for comments. In newer versions, we also have wire labels.
(see also)
What is your LabVIEW version? Also the LabVIEW 2011 cleanup does a better job keeping diagram comments together with the related code compared to earlier version.

Using spool in a procedure

Hi,
I've a package with 6 procedures.
In one procedure I need to load the data into a flat file. The procedure contains only one select statement.
example:
procedure pro_test as
select * from emp;
end pro_test;
Shell script is being used to call one procedure inside the package and that procedure is calling remaining procedures inside it.
connected to database using sqlplus.
Can anyone help me out how I can spool the select statement inside the procedure. Version of oracle is 11g.

Hi,
Why do you want to do
SELECT *
FROM    table_name;
inside the procedure? Why not have your script run the procedure (without the query above), and then do that query afterwards, when you can use SPOOL to put the results in a file?
If you really must write a file from a procedure, here's an example of how to use utl_file.
First, SYSTEM (or some other user with the CREATE ANY DIRECCTORY system privilege) must create a directory, and grant privileges to use it. For example:
CREATE OR RPLEACE DIRECTORY a_dir AS 'C:\Foo\A_Folder';
GRANT ALL ON DIRECTORY a_dir TO PUBLIC;
Typically, SYSTEM does this once, and other people use it hundreds of times.
You might create a file in that directory like this:
CREATE OR REPLACE PROCEDURE write_dept
IS
    f utl_file.file_type;
BEGIN
    f := utl_file.fopen ('A_DIR', 'Dept.txt', 'W');
    FOR r IN ( SELECT *
                   FROM    scott.dept
    LOOP
        utl_file.put_line ( f
                          , TO_CHAR (r.deptno, 'FM00')
                            || ' '
                            || RPAD (r.dname, 15)
                            || r.loc
    END LOOP;
    utl_file.fclose (f);
END write_dept;

Using dynamic value in procedure on column

I want a PL/sql procedure to select the data from the column dynamically into a variable .
My friend suggested its not possible in PL/sql ,its only possible in sql .
What i want is when i execute the PL/sql procedure the a_1 must get the value of the data in the table,i do not want to use execute immediate in pl/sql.
I create a table A
create table A (a1 number,a2 number,a3 number);
insert into a values (1,2,3);
then i create a procedure
create or replace
procedure test_a (var IN number)
as
a_1 number;
i number;
z varchar2(5);
begin
if var=1
then
i:=1;
elsif var = 2
then
i:=2;
z:='A2';
end if;
SELECT 'a'||i into a_1 from a;
end;

I prefer reference cursors over execute immediate if I must do dynamic SQL (and have learned not to do it unless necessary - among other things dynamic SQL is hard to debug and maintain).
The advantages to ref cursors are
* execute immedate will only retrieve one row, ref cursors as many as you want
* easier for me to build the query first, then execute it (though you can do this with execute immediate too) for debugging
You can buiid the query dynamcially but have to be careful to make sure the select list matches the INTO clause on the fetch statements. Although the queries in the example below are hard coded I could have done something like
v_command_c := 'select '||var1||', '||var2||' from '''||table_name||'''';
open refcur for v_command_c;To randomize your column selection use something like the above with IF logic and a randomizer, possibly the DBMS_RANDOM package or a time extraction.
Something like
SET SCAN OFF
SET SERVEROUTPUT ON
DECLARE
--define composite data types
--reference cursor type - structure
TYPE RefCursorType   IS REF CURSOR;
--collection (index-by table) type - structure
TYPE TablesTableType IS TABLE OF user_tables.table_name%TYPE
    INDEX BY BINARY_INTEGER;
--define ref cursors to be used in BEGIN section
UserTablesCursor RefCursorType;
UserViewCursor   RefCursorType;
--define actual index-by tables to be used in BEGIN section
NamesTable TablesTableType;
ViewsTable TablesTableType;
--define internal procedures to be used in this script
PROCEDURE ListItems(RefCursor IN RefCursorType,
    DataTable IN OUT TablesTableType
    ) IS
    Counter   INTEGER := 1;
    TableName user_tables.table_name%TYPE;
BEGIN
    FETCH RefCursor INTO DataTable(Counter);
    Counter := Counter + 1;
    WHILE RefCursor%FOUND LOOP
      FETCH RefCursor INTO DataTable(Counter);
      Counter := Counter + 1;
    END LOOP;
END; --ListItems;
PROCEDURE WriteItems(DataTable IN TablesTableType) IS
BEGIN
    FOR i IN 1..DataTable.count LOOP
      dbms_output.put_line(DataTable(i));
    END LOOP;
END; --WriteItems;

OPEN UserTablesCursor FOR
    SELECT table_name
      FROM user_tables;

Subreport using the same Stored Procedure

I have a main report and a subreport that uses the same stored procedure. The stored procedure has 12 parameters and what I want to avoid is the user having to enter the same parameter values twice. When I created the subreport I put in the parameters + one field, the employee id field so that I could just test it on one employee.
After I entered the subreport into the main report, when I got to refresh the data, it's asking for params for BOTH reports. Is there any way to get around this? Because of the way the stored procedure returns the data, I had to create a subreport instead of just fitting it into one of the footers. I've looked at the subreport link and added the employee id as the key. When I ran it the first time, it returned the wrong date range on the sub.
Help! this thing is Way passed due!!

Right click on the sub report and choose change sub report links
Top left pane contains your main report parameters use > to add
In the bottom left corner of that dialog then scroll down until you see the corresponding sub report parameter
Repeat for each parameter
This should then take the main report params and pass into the sub report

Error Using Sequence in Weblogic

I tried to use Sequence object in weblogic to generate auto-imcremental integers
for my db insert keys. I first create a mydbsequece in oracle database. Then,
I built a class in which I obtain a dataSource using jndi to look for my dataSource.
And then use the ds to getConnection. After I had the connection, I do the following:
Sequence sequence = new Sequence(con, "mydbsequence");
int i = sequence.nextValue();
When I call sequence.nextValue() method, I got the following error message: NullPointerException
at Weblogic.jdbc.rmi.SerialConnection.createStatement(SerialConnection.java:65).
Does anyone know what causes this error? and How do I fix it? Please advise me
on this. Thank you very much.

QinSequence is a non-standard JDBC object. It is an Oracle-specific class, which presumably
takes a standard java.sql.Connection in it's constructor. Oracle has repeatedly created
such new classes with methods claiming to take java.sql.* arguments, but in fact they
require an Oracle-specific class. In this case, however, we might succeed anyway if
we dig some. Can you show me the entire stacktrace of the exception?
Please take the attached jar file, and put it in front of all the weblogic stuff
in the server's classpath, and repeat the problem and show me the new exception.
From the line, I am assuming you're on the 6.1 version of WebLogic. If not, forget the
jar, and let me know.

Use of variable in Procedure

I created a global variable that contains a result of a query.
I used it in a procedure using SQL but when I run the prcedure I have the following error :
com.sunopsis.sql.SnpsMissingParametersException: Missing parameter
Could you tell me how to use my variable ?
My SQL Code is the following and I bolded the variable
SELECT A.SESS_NAME ,
A.SCEN_VERSION,
A.SESS_BEG ,
A.SESS_DUR,
C.NNO,
RTRIM(LTRIM(B.STEP_NAME)) TABLE_NAME

Thank you

Thanks a lot it did not fail.
Now I am going to check if my procedure does something.
Steps to use a variable resulting from a query in a procedure. ( In my case I used a alphanumeric variable )
1) I declare a global Variable My_Variable. I chose
- type 'Alphanumeric'
- default value SELECT TO_CHAR(DATE_LAST_PROCESS) FROM PS_S1_ODI_BASCULE
- action 'Dernière valeur'
- I refresh my variable by running the query on the RDBMS
2)In the procedure I refer to my variable by writing '#My_Variable'. My SQL Code becomes
SELECT A.SESS_NAME ,
A.SCEN_VERSION,
A.SESS_BEG ,
A.SESS_DUR,
C.NNO,
RTRIM(LTRIM(B.STEP_NAME)) TABLE_NAME
,SUM(C.STEP_DUR)
, SUM(NB_INS) NB_INS
FROM COUNT_TMP D , SNP_SESSION A , SNP_SESS_STEP B, snp_step_log C
WHERE
'PS_' || RTRIM(LTRIM(B.STEP_NAME)) = D.TABLE_NAME AND
A.SESS_BEG >= TO_DATE( '#DATE_BASCULE' , 'DD/MM/YYYY') AND
A.SESS_NO = B.SESS_NO AND
B.SESS_NO = C.SESS_NO AND B.NNO = C.NNO
GROUP BY A.SESS_NAME , A.SCEN_VERSION ,A.SESS_BEG ,A.SESS_DUR, C.NNO ,B.STEP_NAME
ORDER BY A.SESS_NAME , A.SCEN_VERSION, C.NNO
