Connecting to a different schema within a stored procedure

Hi Peopl,
I have a Stored proce "TestProc" which is a part of schema "test1"... Now within this proc i need to connect to a different schema "test2", fetch some data from its tables and disconnect from the same, but not from the original schema "test1". Both the schemas are located on the same database server so i guess no different network connection. I hope u guys got my question... if not tell me... How shud i approach this requirement....

This would all be handled within the same session, so there is no extra connect or disconnect involved here.
The user 'test2' needs to grant the appropriate privileges directly to 'test1'. These grants must be direct and not through a role. If the procedure is just selecting data from test2, then test2 needs to:
test2>grant select on tablea to test1;where tablea represents a table in the test2 schema. There would be a separate grant for each table in test2 accessed by test1.
The code in test1 can refer to the table in test2 as test2.tablea, or you can create a private synonym in test1:
test1>create synonym tablea for test2.tablea;so every reference to tablea does not need to be qualified with the 'test2.' prefix.

Sending email from within a stored procedure

Is it possible to send and email within a stored procedure written in PL/SQL. I have searched this site and the web for an Oracle package which simulates a mail agent written in PL/SQL, but I have not had any success.
null

Well, on NT one way we did it was to link to kernel32.dll so we could execute OS commands (WinExec), and did the email that way.
Here's a bit of script to try:
connect sys/@db;
drop library kernellib;
CREATE LIBRARY kernellib as 'c:\winnt\system32\kernel32.dll';
show errors
CREATE OR REPLACE PACKAGE UTIL IS
function run(lpCmdLine IN varchar2, nCmdShow IN binary_integer) return binary_integer;
end;
show errors
CREATE OR REPLACE PACKAGE BODY UTIL IS
function run(lpCmdLine IN varchar2, nCmdShow IN binary_integer) return binary_integer
AS EXTERNAL
NAME "WinExec"
LIBRARY kernellib
parameters (lpCmdLine STRING, nCmdShow long);
end;
show errors
Then you just call util.run() with an appropriate command line to send email. Bit of a hack, but it depends on what you want to do with it. Another hack would be to use the UTL_HTTP package to submit a form to your web server and use a CGI program to send the email.

Creating a table/view or temporary table from within a stored procedure

Hi Gurus,
Can someone tell me if it is possible to create a table (or view) from within a stored procedure.
PROBLEM:
In fact I need to create a report at back end (without using oracle developer forms or reports). This report requires creating several tables to hold temporary report data. If I create a sql*plus script for this, i works fine, because it can run DDL and other sql or pl/sql statements sequencialy. But this sql*plus script cannot be called from application. So, application needs an stored procedure to do this task and then application call that procedure. But within stored procedure, i am unable to create table (or run any ddl statement). Can somebody help me in this?
Thanks in Advance.

Denis,
The problem with Nicholas' suggestion isrelated to the fact that now you have two components
(a table and a stored procedure)
I don't see any problem to have "two
components" here. After all, what about all others
tabes ? This is only one more, but I don't understand
why want manage less objects, that implies more code,
more maintenance, and more difficulties to debug.
Needless to say about performance...
Nicolas.The same reasons apply if you were forced to declare all PL/SQL variables publicly (outside the stored proc.) rather than privately (from inside the stored proc). Naming conflicts for one. If the name that you want to use for the GTT already exists, you need to find a new name. With the SQL Server type local/private declarations, you wouldn't have that problem.
I can see how performance would be the same or better using GTTs. If the number of records involved is low, this is likely negligable.

How to determine the load on the oracle server within a stored procedure?

Hi,
I have a subset of commands in my stored procedure that I would like to execute them only if there is not significant load on the database sever.
What would be the best way to measure the amount of load on my database server within a stored procedure?
Thank you,
Alan

It is not that easy.
This stored procedure is called by a job that runs every hour. Half of the stored procedure code are mission critical and must run by any means necessary! The second half must run right after the 1st one and is nice to do.
If I assign a lower priority it makes the situation worst, because then the job might take 3-4 hours and the same jobs run on top of each other over and over.
I just oversimplified the situation, The point is I prefer not to run the less important PLSQL code rather than assigning lower priority and stretch it over timeline. These hourly jobs are not Oracle jobs and cannot run on top of each other. Last time this happened and I had to kill 12 sessions! (12 jobs in 12 hour)
Trust me, estimating the load on the database server is the only solution.
When I say load on the server I mean the load resulted from other oracle sessions on the same database server. This server is a single instance Oracle 10g Enterprise on Solaris. All I need is just accessing to some meaningful counters.
Any help would be appreciated,
Alan

ALDSP 3.0 -- schema owner for stored procedure or SQL Statement

Using ALDSP, I have a need to create a physical service based on a stored procedure or a SQL statement. I am wondering what will happen when I move to another deployment environment where the schema owner changes. In our QA and Prod environments, we have a different schema owner for all tables in the application (the DBAs believe this prevents unwanted updates to a prod environment). DSP elegantly supports this for normal table- and view-based physical services by mapping schemas through the DSP console after deployment. Will I get the same type of mapping capability for stored procedures and SQL statements? I noticed that I can add a SQL-based function to a physical service...is there a way to pass in the physical table name from that data service to the procedure or SQL statement?
Thanks,
Jeff

Schema name substitution should work for stored procedures just like it does for tables. If it doesn't - report a bug.
You don't get any help for sql-statement based data services - dsp doesn't parse the sql provided. One thing you could do is use the default schema (following the user of your connection pool), and not specify the schema in your sql-statement.

Java App connection to an Oracle Database through Oracle Stored Procedure

My team's access to its Databases (Oracle only) is restricted to access through Oracle Stored Procedures that are part of the Oracle Database. So, in my Java App I need to call the Stored Procedure that will give me the access to the table that I need, declare the right parameters and execute the command. The Stored Procedure will then hand me the data I need.
I am finding support on the web for creating Stored Procedures in Java, but that is not what I need.
Can anyone post here a class that addresses this, or point me to a link that will shed some light on it?
Thanks

I am looking for Java code that will do what this .NET code below does (connects to a database and writes data to the table through an Oracle stored procedure that is part of the Oracle Database.)
So learn Java, learn JDBC and translate the requirements; don't attempt to translate the code as the platforms are too different.
From a quick glance it looks like a JDBC CallableStatement can do the job.

Connection object is getting closed before the stored procedure is complete

Hi Everyone,
I am facing an issue where by the java connection object is closed before the stored procedure it is connected to is complete.
I am not sure if the fault is in SP or Connection pool.
After spending some time, i could able to figure out that the procedure is taking a tad more time for processing as there are over 1000 records in the database tables it is dealing with.
Would that be a potential cause ? or Am i required to handle it in Java only ?
I want to know what could be possible causes for this issue ?
Please Help.
FYI,
The following are the logs which says,
XYZ (Stored Procedure) : Start Time is 1349217771302 Procedure started here

Hi ,
Thank you all for your quick response.
Well it's my bad i dint provide you any code to look into thinking that i am dealt with a gen issue and also i am too paranoid to post any code i am dealing with in the forum (i am sorry).
But here is some information for you,
Database : Oracle 10g
Java: 1.5 version
We are using only One connection object for the entire java backend process .
The SP is of over 1000 lines of code which for obvious reasons i can't past it here but this morning i figured out an issue in SP where by a query taking way more than usual time to execute which led to SP's poor performance and also the reason for why it is taking very long time than usual.
This query is a simple SELECT query where it is trying fetch over 2000 records from a table of over 3 million records. The execution time is over 30-40 seconds which is the root cause of SP's poor performance.
When i eliminated this from the logic and ran the query it could able process (inserting huge volume around 5000 records of data) in 1 second instead of 3-4 minutes earlier.
I tried to replicate this issue (which occurred in our production server) in my local system but no luck as there was no connection issue here but only the substantial time difference.
We are using a customized connection pool which is as follows,
I am not sure what's going on here because it seems to be greek and latin to me.
What we are doing in our DAO is we are using method of the below ConnectionPool.getInstance(SCHEMA) to get the connection object.
Looking forward to seeking advice from you on how connection pool in general works.

Temp Table within an Stored Procedure

I'm pretty new to Oracle, but I have been developing in MS SQL for about 15. So I'm still getting use to the syntax and features within Oracle.
I'm trying to create a stored procedure that has two temporary tables within it, and then queries both them tables and inserts the results into a table.
I created the script but when they try to run in on the server it wont run. Can you guys tell me what I'm doing wrong?

Some people still sound mad at me because I have two queries and use temp tables
Because in Oracle, unlike in sql server, you generally do not NEED temp tables at all.
One of the biggest mistakes new Oracle developers make is to use PL/SQL when SQL will do the job just fine. Using PL/SQL when it isn't needed generally makes the code slower, less scalable and harder to maintain.
One of the biggest mistakes sql server developers make when they use Oracle is to use temp table when they aren't needed. They try to write code in Oracle exactly the same way they wrote it in sql server. That creates temp tables that aren't needed, makes their code perform horribly and also makes it less scalable and harder to maintain.
Oracle works differently and generally doesn't need ANY temp tables. You need to learn about how Oracle handles transactions and read consistency and how writers do NOT block readers and vice versa.
Create a new thread and post FORMATTED code that shows the PROBLEM you are trying to solve and we can show you the proper way to solve it. That 'proper way' will likely NOT include any need for or use of temp tables.

How do I insert multiple values into different fields in a stored procedure

I am writing a Stored Procedure where I select data from various queries, insert the results into a variable and then I insert the variables into final target table. This works fine when the queries return only one row. However I have some queries that return multiple rows and I am trying to insert them into different fields in the target table. My query is like
SELECT DESCRIPTION, SUM(AMOUNT)
INTO v_description, v_amount
FROM SOURCE_TABLE
GROUP BY DESCRIPTION;
This returns values like
Value A , 100
Value B, 200
Value C, 300
The Target Table has fields for each of the above types e.g.
VALUE_A, VALUE_B, VALUE_C
I am inserting the data from a query like
INSERT INTO TARGET_TABLE (VALUE_A, VALUE_B, VALUE_C)
VALUES (...)
How do I split out the values returned by the first query to insert into the Insert Statement? Or do I need to split the data in the statement that inserts into the variables?
Thanks
GB

"Some of the amounts returned are negative so the MAX in the select statement returns 0 instead of the negative value. If I use MIN instead of MAX it returns the correct negative value. However I might not know when the amount is going to be positive or negative. Do you have any suggestions on how I can resolve this?"
Perhaps something like this could be done in combination with the pivot queries above, although it seems cumbersome.

How to get connection of the db lite from java stored procedure?

Hello! All.,
I have a written java stored procedures to assign sequence keys, and update some tables. The procedure is working as per our need by using the following connection information.
try {
int rowFetched = 0;
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
// connect to the database
Connection conn = DriverManager.getConnection("jdbc:polite:polite",
"system", "manager");
My question is, It is possible in db lite to get a default connections like we use in the enterprise database
conn = new OracleDriver().defaultConnection();
Could anybody please shed some light on this.

Hello Upi! out of curiosity if you happen to know the answer for the following, I do appreciate it.
Hello! We are using BC/ADF JClient to select and for any DML operation against Oracle Lite database. We may have more than one user(s) log on to our application, so we requires to authenticate oracle lite user credential using JDBC dynamically.
I am utilizing the features of JCLoginDialog.java and manipulation bc4j.xcfg file. This work real good for accepting username/password credentials dynamically, since we have multiple database in one computer I have to accept DSN name and if possible built my own configuration file.

Is it possible to use iFS API within java stored procedure?

question:
is it possible to use the iFS API for file handling
within a java stored procedure (which is invoced by a trigger)?
is there an "elegant" workaround if it is not possible?
problem:
my java code using the iFS API works fine outside
the java stored procedure
but invoked via trigger as java stored procedure
it throws following exception:
IFS-20102: Unable to start service (IfsDefault)
i am using:
oracle 9.0.1
oracle internet file system 9.0.1.1.0
windows 2000
thanks

thanks for your help
i looked through the applications developers guide
the basics behind advanced queueing (as far as i understand) is:
program A inserts a message into the queue - and program B gets message from the queue and processes it
question 1:
but what is the difference between advanced queuing and a queue i create by myself
(simply with a database table) and let application B (which runs in a loop)
check if the queue is filled
or am i missing something important which makes advanced queuing more practicable for my problem?
question 2:
you wrote about advanced queuing support in iFS 9.0.3, but the newest version i found was iFS 9.0.2
did you reffer to the advanced queuing mechanism in general or to a spezial queuing feature in iFS 9.0.3?
thanks

SELECT query from within a stored procedure

DB Version:10gR2
For auditing purpose, i just want to execute the query within the IF condition, and get the results for spooling. But i am getting PLS-00428 error. Can't i just execute a SELECT query and get its results displayed in SQLPLUS so that i can spool them?

Within PL/SQL code, the results of a query have to be returned from the SQL engine to the PL/SQL engine, hence why it is asking you to include an INTO within your query. Note that the PL/SQL engine is running on the database server so it has no interface to display output to. To output from within PL/SQL you would have to write the data out yourself to whatever output you want e.g. use DBMS_OUTPUT to put the data to the standard output buffer (which can then be read by SQL*Plus if serveroutput is set to "on") or written out to a file on the server, or written out to a table.
You are assuming that because you can execute SQL from SQL*Plus and spool the output, you can do the same within PL/SQL. This is not the case. When SQL*Plus issues a SQL statement, it goes to the SQL engine and the results of that cursor (as an SQL query is a cursor) are collected by SQL*Plus and it displays them itself. When PL/SQL issues a SQL statement, it goes to the SQL engine and the results of that cursor come back to PL/SQL. PL/SQL doesn't have a display mechanism, so the results have to be collected INTO something.
Hope that's clear.

Running "Host" From Within a Stored Procedure

Hellow
Wanna Run a "Host" Command from Within A SP
or DB Trigger
Any Help is Appreciated !!
Regards
Tariq

the only way to run an OS command from within the database is through extproc
(works from 8.x onwards).
Essentially, you have to:
- modify the database listener to support external procedure calls
- create a library object
- create a C - program and compile it as a shared library
- write a wrapper function in PL/SQL that calls the shared library
I can send you an example, if you want.

Import a schema (tables, Views, Stored Procedures) on logical standby

Hi,
We have a logical standby for reporting purpose. The logical standby build through data guard
we need to import a new user in logical standby using import utility. The user dump contain tables, views, procedures, packages, roles).
The new user import has to go in users tablespace.
Is is possbile to import a new user in logical standby and what are the steps.
Thanks in advance

Hi,
Can you give me more details about your envirnoment configuration, O/S, DB version.
But generally i don't think that is this possible becuase as you know standby only for cloning the primary database, so you can import it on the production then it will be transfered to the logical standby database.
