Passing variables to a procedure inside a database trigger

Hi, I am new to oracle Forms . I am having a table in database . For that table i had written a database trigger which will fire after insert or update . I am using a procedure inside the Trigger . I want to pass arguments to the procedure which is being called in the trigger . The variables which i want to pass to the procedure are one is a primary key and the other is a normal cloumn which are in the same table for which the trigger is written. Can anybody help me regarding this.?

> But when i m calling it with forms i m getting an error
You cannot call a database trigger from forms. A trigger is part of the table, e.g.:
create trigger my_trigger
before insert or update or delete on my_table
for each row

/No errors but the procedure doesn't executed !!!!!

1) If you are using autonomous transactions for anything other that writing log data that you want to preserve even if the triggering transaction fails, you're probably doing something wrong. There is no reason to use an autonomous transaction here.
2) You don't want to send email from a trigger. You don't want to do anything non-transactional in a trigger. Oracle will, for example, rollback and re-execute parts of a statement for write consistency. If you send email in a trigger, you may get multiple emails for a single update. You may also get emails for updates that were never committed. And if the email server happens to be down, your transactions will fail.
3) If you use an autonomous transaction, the trigger will have a completely different transaction context from the parent. So when you query the table within the trigger, you won't be able to see any of the uncommitted changes including the changes that caused the trigger to fire. My guess is that you are assuming that the row that you inserted is visible to the trigger.

Passing variable number of arguments in a stored procedure

Hi Team,
i am facing a problem. I have a dynamic form which contains some checkboxes. The number of checkboxes are dynamically generated on querying the database. On the form submission i want to call a stored procedure that will update the values in the database. i want to know that is there any way to handle variable number of arguments in the stored procedure or can i get the variables through some session context and use it in my stored procedure.
Any help is greatly appreciated.
Thanks&Regards
Saurabh Jain

Hi Saurabh,
The method in which stored procedures are called on form submit is something as follows.
Let us take your scenario of a form which has multiple checkboxes and a submit button. On clicking the submit button, this form data is submitted using either get or post. The form's submit action invokes a procedure.
The HTML form code will look something like this..
htp.formOpen( curl => 'URL /myProcedure',
cmethod => 'post' );
htp.formCheckbox( cname => 'myCheckbox'
cvalue => 'A');
htp.formCheckbox( cname => 'myCheckbox'
cvalue => 'B');
htp.formCheckbox( cname => 'myCheckbox'
cvalue => 'C');
htp.formSubmit( cname => 'myButton',
cvalue => 'OK');
Now, whenever the submit button is clicked, all these form values are passed to our stored procedure 'myProcedure'.
"myProcedure" looks something like this.
procedure myProcedure
myCheckbox IN sys.owa_util.vc_arr,
myButton IN VARCHAR2
is
begin
end myProcedure;
The point to be noted here is that the name of the variable being passed in the procedure is the same as the name of the HTML element being created in the HTML form. So, there is a direct mapping between the elements in the HTML form and the procedure parameters.
Another noteworthy point is that since you have multiple checkboxes in your HTML form, it is impractical to name all the checkboxes differently and then pass those many parameters to your procedure (Imagine a scenario where there are a hundred check-boxes in an HTML form!). So portal allows you to give the same name (cname) to all the checkboxes in your HTML form, and if multiple checkboxes are checked, it will return all the checkbox values in an array (Note the usage of "myCheckbox IN sys.owa_util.vc_arr" in myProcedure).

Pass BPC SSIS variable to stored procedure

Dear All
We have a ssis package in which there is data flow task. There
is a OLEDB source which uses “Data access mode” as sql command. We used OLEDB data source instead of execute sql task as the outuput is table format generated in Stored proc which is used in following task
This task calls a stored procedure with a input parameter which will be appset name.   [EXEC ProcName '@BPCAPPSET']
The stored procedure is executing fine without any issues.But when I pass variable containing appset name to that stored procedure its not taking properly and package ending successful.
The variable is “BPCAPPSET” it contains appset name which
will be taken front end.
   However to test if this value is taken by stored procedure
or not, I tried to hardcode and pass appset name to stored procedure. i.e exec
ProcName Appset1.
Appset1 is existing appset. It worked fine. But we want to
put this package in all land scapes, such that whenever it is triggered it will
take the appset as parameter and does the calculation in stored procedure.
   Please advice how to pass this variable to stored
procedure.
regards
Prasad

Hi Roberto
Thanks for your mail.
I have tried, but I am getting error that @BPCAPPSET scalar
variable must be defined.
I believe that @BPCAPPSET is system defined variable which
will be passed from Data manager package. May be this is the reason it is not
recognizing this variable?
If so, should I define a variable in SSIS. How can we
assign value of @BPCAPPSET to the newly defined variable?
Please advise. Attached screenshot.

Passing Variable Number of Parameters to Cobol Stored Procedure

Hi. I have a web front end that needs to access several different tables via Cobol stored procedures. It seems simple enough to call the stored procedures straight away (DAO Pattern perhaps?) but my boss is insistent on having an intermediate Cobol program that decides which table to access. I think he at a bigger picture than I can see.
The problem lies in the number of parameters that need to be passed to the stored procedures; some need 3, others needs 5, a few need 4. The only two solutions that I can think of are to pass EVERYTHING (we're talking 50 parameters or so) to the intermediate stored procedure and then pulling only what is needed from that data set to access the desired table. Solution number two involves passing everything to a temp table and then pulling what is needed from it. The former solution seems a little cleaner but still involves passing a lot of parameters. If Cobol could handle some sort of dynamic memory allocation (Vector) there seems to be a possible solution there. Though, as far as I know, that isn't possible.
Any ideas are much appreciated.
Thanks in advance,
Chris

Pass PL/SQL Record variable to Stored procedure in Java

Can some one please give me a code snippet for passing a Record Type variable returned by Stored Procedure. Following is the scenario.
A record type variable REC_VAR is made of three columns of a table as follows
EmpNo Number, Empname Varchar2(50), Zip_Code Varchar2(5).
I am populating this variable in Java code and passing it to Stored Procedure.
Can I referance Record Type variable in a Oracle package from Java code.
How would I define these variables as per tables column type and pass to SP in a java program.
Thanks,

If you need to call a procedure which has yet to be defined in your package, you can use forward declaration...
That means that you declare the procedure/function before the place it's going to be called (typically people do this at the top of the package) without providing a body for the code...
PACKAGE BODY        ms_gen_process_email as
   PROCEDURE get_email_details
      p_metric_name     IN   VARCHAR2,
      p_current_stage   IN   VARCHAR2,
      P_ACTION          in   varchar2,
      p_email_type_table out email_type_table
   ); -- Forward declaration of get_email_details procedure
    procedure process_email_master(
      p_metric_name     IN   VARCHAR2,
      p_current_stage   in   varchar2,
      p_action          in   varchar2,
      p_pid             in    number,
      p_object_id       in    varchar2

Application inside an application and using URL parameter to pass variable values

hello
My requirement is to create a design studio dashboard that will have 2 applications and I should be able to pass variable values from application 1 to application 2. All this should happen in 1 dashboard application. I have tried using open document functionality
Application1.openNewWindow(URL link to application 2) . It doesn't meet my requirement as I am required to login to the other application in a new window.
Is it possible to add 2 applications in one dashboard.
thanks,
Bhat

Hi Bhat,
I don't know if it is possible to open it in the same Page. But you can try using the Opendoc Parameter which allows you to enable you to pass the credentials you have used in the current Dashboard.

Iam passing an array of objects from Java to the C
file. The total size of data that Iam sending is
around 1GB. I have to load this data into the Shared
memory after getting it in my C file. Iam working on
HP-UX (64-bit). Everything works fine for around 400MB
of data. When I try to send around 500MB of data, the
disk utilization becomes 100%, so does my memory
utilization and I get a "Not enough space" when I try
to access shared memory. I have allocated nearly 2.5GB
in my SHMMAX variable. Also, I have around 45GB of
disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?

STORED PROCEDURE & DATABASE TRIGGER

제품 : FORMS
작성날짜 : 1995-11-07
* STORED PROCEDURE
1. Oracle Forms 4.5에서는 PL/SQL Code를 Server-Side에 저장하거나 Forms 내 Trigger, Procedure로 갖을 수도 있다.
다음과 같은 경우 Procedure를 Database Server에 저장하는 방법을 선택하는
것이 좋다.
- Procedure가 Standard한 기능을 제공하여 다른 Tool이 공유할 수 있을 때.
- Procedure가 중요한 DML 기능을 가질 경우.
- Oracle Forms 4.5에서는 PL/SQL의 Version을 1.1까지 지원하므로, PL/SQL
Version 2.X 의 기능이 필요한 경우.
2. Stored Procedure의 제한사항
(1) Server가 7.0 이상이어야 한다.
(2) Pass되는 Variable은 2000 Byte이하이어야 한다.
- 2000이 넘으면 Truncate가 되고, PL/SQL에서 Value_Error Exception이
발생한다.
(3) Menu PL/SQL에서는 Stored Procedure와 Function을 부를 수 없다.
(4) Stored Subprogram의 정의가 바뀐 경우, Forms를 다시 Server와 Connect
하기 전에는 영향을 주지 않는다.
3. Oracle 7 Server 에서 제공하는 Standard Package들
- dbms_alert
- dbms_ddl
- dbms_describe
- dbms_lock
- dbms_mail
- dbms_output
- dbms_pipe
- dbms_session
- dbms_snapshot
- dbms_standard
- dbms_transaction
- dbms_utility
< Oracle7 Developers Guide 참조>
4. Calling Stored Procedures
(1) Database Procedure는 Server-Side PL/SQL Engine에 의해 실행되도록
Design된 PL/SQL Block이다.
(2) Stored Procedure를 Call하기 위해서는 EXECUTE Privilege가 필요하다.
(3) Server-Side Procedure와 Forms에서의 PL/SQL의 중요한 차이점은
Server-Side 에서는 Forms의 Bind Variable (:Block_Name.Item_Name 등)
을 인식하지 못한다는 것이다.
(4) Parameter/Return이 가능한 Data Type
- VARCHAR2 : Maximum of Varchar2(2000)
- NUMBER
- DATE
- BOOLEAN
제한사항
- TABLE%ROWTYPE, TABLE.COLUMN%ROWTYPE으로 정의된 것은 Reference가
안된다.
- Unsupported Parameter나 Return Value를 사용하면 다음의 Error가
발생한다.
* PL/SQL error 313 at line xxx, column yyy 'PROCNAME'
not declared in this scope.
* PL/SQL error 201 at line xxx, column yyy identifier 'FUNCTNAME'
must be declared.
(5) Formal Parameter의 Default Value
- Defulat Value는 제공하지 않는다.
- User가 임의로 줄 수 있다.
- Procedure Private_Test(a in VARCHAR2 := 'Hello' b in
VARCHAR2 := 'There') IS
BEGIN
Dbms_Output.Put_Line(a);
Dbms_Output.Put_Line(b);
END;
(6) 다른 User의 Stored Subprogram이나 Remote Database를 Call하려면
- User Name이나 Database Link명을 숨기기 위하여 Synonym을 생성하여야

How to pass variable to SQLPLUS in a ksh script?

Hi,
I am writing a ksh script which will use sqlplus to run a sql and pass 2 variables as the SQL request. In the ksh script, I have 2 variables which are $min_snap and $max_snap holding 2 different numbers.
Inside the same script, I am using SQLPLUS to run an Oracle SQL script, which request to enter 2 set of numbers, one at a time. Normally running situation, I can enter the number from the keyboard, but since I am writing a script, I want to pass those numbers by passing variables in the script? How can I do it?
Please help!
here is my ksh script,
#!/bin/ksh
if [ "$1" = "" ]
then
echo "Usage : delete_snapshot.sh <db_name>"
exit
fi
export ORACLE_BASE=/oracle1/app/oracle
export ORACLE_PATH=.:/oracle1/app/oracle/product/8.1.7/tune
export ORACLE_HOME=/oracle1/app/oracle/product/8.1.7
export ORACLE_RDBMS=$ORACLE_HOME/rdbms/admin
export ORACLE_SID=$1
curr_time=`date +"%m/%d/%y %H:%M:%S"`
log_file=/home/mdbtuner/stats/sppurge/log/{$ORACLE_SID}_`date +"%Y%m%d"`.log
#echo $log_file
echo "****** Delete Snapshot for $ORACLE_SID at $curr_time ******" >> $log_file
#echo "****** Delete Snapshot for $ORACLE_SID at $curr_time ******"
#echo $ORACLE_HOME/bin/sqlplus -S perfstat/perf$ORACLE_SID@$ORACLE_SID
cd /home/mdbtuner/stats/sppurge
$ORACLE_HOME/bin/sqlplus -S perfstat/perf$ORACLE_SID@$ORACLE_SID << EOF > $min_snap
@min_snapid.sql
exit;
EOF
$ORACLE_HOME/bin/sqlplus -S perfstat/perf$ORACLE_SID@$ORACLE_SID << EOF > $max_snap
@max_snapid.sql
exit;
EOF
echo $min_snap $max_snap
cd $ORACLE_RDBMS
#$ORACLE_HOME/bin/sqlplus -S perfstat/perf$ORACLE_SID@$ORACLE_SID << EOF >> $log_file
$ORACLE_HOME/bin/sqlplus -S perfstat/perf$ORACLE_SID@$ORACLE_SID << !
@sppurge
$min_snap
$max_snap
exit;
#EOF
Thanks in advance!

Thank you for response, Paul.
Have you ever used statspack? or sppurge.sql?
When you run $ORACLE_HOME/rdbms/admin/sppurge.sql, it waits for user to enter losnapid and hisnapid manually from the keyboard.
My trouble is to have a script to delete old snapshot which are 3 weeks old. So I create min_snapid.sql and max_snapid.sql to hold two variables.
Based on your solution, I tried it but it doesn't work.
It returns the error messages as following....
Warning
~~~~~~~
sppurge.sql deletes all snapshots ranging between the lower and
upper bound Snapshot Id's specified, for the database instance
you are connected to.
You may wish to export this data before continuing.
Specify the Lo Snap Id and Hi Snap Id range to purge
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for losnapid: Using exit; for lower bound.
Enter value for hisnapid:
User requested Interrupt or EOF detected.
Enter value for hisnapid:
User requested Interrupt or EOF detected.
WARNING: LoSnapId or HiSnapId specified does not exist in STATS$SNAPSHOT
Enter value for hisnapid:
User requested Interrupt or EOF detected.
Purge of specified Snapshot range complete. If you wish to ROLLBACK
the purge, it is still possible to do so. Exitting from SQL*Plus will
automatically commit the purge.

Passing Arguments to Login-Procedure

Hi,
i was trying to pass some own/more connection infos to our login procedure.
I used the "CON=" parameter.
CON=PROGRAM_USER=test_user@
PROGRAM_PASSWORD=pasword_hash@PROGRAM_CON_NAME=Test Connection
Is there a better way to pass such infos?
First I thought about the connectstring (e.g. ConnectString='DSN=myDatabase;UserDefinedOption=ABC') but i didn't find a way to access these infos in my login procedure.
How do i change the connection-name property in my login procedure?
set option name=Test Connection; -- does not work
Regards
Stefan

Hi Stefan,
See the following sqlanywhere-forum thread for more details about changing the connection string after login - it can't be done (and really isn't intended for that purpose):
http://sqlanywhere-forum.sap.com/questions/8730/is-there-a-way-to-set-con-property-connection-apart-from-the-connection-…
So in summary, no, there isn't a way to change the connection name, and as Arcady points out, it isn't a very secure mechanism to transfer passwords. Arcady is also correct in that you should call the login procedure directly from your application.
There are two issues here:
1) Changing connection name information after login / passing information around on your connection
Instead of storing the information in the 'Name' connection property, you probably just want to use a connection-level variable or a customer user-specified database option (created by 'DBA' authority in SQL Anywhere 12 and lower or with the SET ANY USER DEFINED OPTION privilege in SQL Anywhere 16 ) to pass along information from the login procedure:
    CREATE VARIABLE myVar VARCHAR(100);
    SET myVar = 'Hello, World!';
    SELECT myVar;
or
    SET OPTION PUBLIC.custom_option = 'default'
    SELECT * FROM SYS.SYSOPTION;
2) Creating a secure, custom, login procedure against another table
If you're going to be using just one database user with one set of permissions, you should look to pass the custom authentication information after the database connection has been made (hopefully over a strongly encrypted connection, for maximum security), and ideally using a prepared statement with bound parameters from the programming API you're using. Your application can then handle any SQL exceptions that are thrown from the login procedure statement and log-out the user from the application at that time.
You are correct in that this will need to be done outside of the original login procedure (that should really be verifying the supplied database username and password).
e.g. in Java:
       ==================
       Connection con = DriverManager.getConnection( "jdbc:sqlanywhere:uid=DBA;pwd=sql" );
       String sqlStr = "CALL sp_custom_login( ?, ? ) ";
       // Prepare the statement
       PreparedStatement stmt = con.prepareStatement( sqlStr );
       // Set values
      stmt.setString( 1, 'userName' );
      stmt.setString( 2 'password' );
       // Execute the statement
       try {
           int iRows = stmt.executeUpdate();
       } catch (SQLException ex) {
             // Can't log in - log user out of application...
             ex.printStackTrace();

Passing variables from shell script to separate sqlplus script

Hi, I am having issues passing variables to a separate sqlplus script invoked by the shell script, e.g.
#!/bin/sh
DB_NAME=TEST
PWD1=PA55W0rd
echo exit | sqlplus / as sysdba @${DB_NAME}.sql ${DB_NAME} $PWD1 >> ${DB_NAME}.sql
exit 0
The script picks up the $DB_NAME variable fine, and therefore invokes the required sql script.
However, when I pass the variable $PWD1 to the sql script I get an error.
The script creates a database link:
create or replace procedure new.link
is
begin
execute immediate 'create database link TEST
connect to TESTSCH identified by '$PWD1'
using ''TEST''';
end;
exec new.link;
output is:
ERROR at line 1:
ORA-00911: invalid character
ORA-06512: at "NEW.LINK", line 4
ORA-06512: at line 1
any help appreciated!

@} [arg ...]
Specifies the name of a script and arguments to run. The script can be called from the local file system or from a web server.
SQL*Plus passes the arguments to the script as if executing the file using the SQL*Plus START command. If no file suffix (file extension) is specified, the suffix defined by the SET SUFFIX command is used. The default suffix is .sql.
See the START command for more information.

Data items you wish to pass to parameters in the script. If you enter one or more arguments, SQL*Plus substitutes the values into the parameters (&1, &2, and so forth) in the script. The first argument replaces each occurrence of &1, the second replaces each occurrence of &2, and so on.
>
... clearly explaining that SQL*Plus substitutes the substitution variables &1, &2 etc. in the script with the passed in arguments.
Your script was including a Unix style substitution, not an SQL*Plus script substitution, so that's seems to be the most likely cause of your problem.
And still you haven't come back to say whether it's worked for you or not... leaving others guessing as to whether you still need help.

Getting error while calling procedure from remote database

When I am trying to call child procedure from remote database I am getting below error:
ORA-02064: distributed operation not supported
ORA-06512: at "NMUSER.NEW_CUST_UPLOAD", line 740
(P.S. on line no 740 I issued "commit;" )
I checked rights,synonym on all the objects they are fine.

Oracle Error: ORA-02064
Error Description:
Distributed operation
not supported
Error Cause:
One of the following
unsupported operations was attempted:
1. array execute of a remote update with a subquery that references a dblink,
or
2. an update of a long column with bind variable and an update of a second
column with a subquery that both references a dblink and a bind variable, or
3. a commit is issued in a coordinated session from an RPC procedure call
with OUT parameters or function call.
