SQL & PL/SQL :: Writing Procedure In User 2 Schema Accessing Table Product - Not Compiled?
Dec 17, 2010
I have got 2 users as user1 and user2.I have used the following statements from user 'user1':
create role GENEVAOBJECTS;
grant select, insert, update, delete on PRODUCT to GENEVAOBJECTS;
grant GENEVAOBJECTS to user2;
In the above statements, product is a table. Now, I could able to access this table from user 'user2'. But however if I write a procedure in user2 schema accessing the table product, then the procedure is not getting compiled.
create or replace procedure test_prc as
v_test number(9);
begin
select product_id into v_test
from PRODUCT where rownum=1;
A single master schema where many developers are accessing. all share same password.
now i would like to trace all the changes made by each users. so i create a individual users for all and grant permission to access that schema.do i have a possibility of auditing the changes did by each user for that particular schema
connect the following concepts/information I've been collecting. This is not my field but I'm interested in filling some of mine conceptual/technical gaps.
From a JDBC perspective, one of the benefits of Prepared (and so Callable) statements have over the regular ones is that the statement is "compiled"(*) once and then reused (performance gain).
(*) for SQL statements: building of parse tree and exec.plan
In which way can this notion be extrapolated to invocation of Oracle Stored Procedures through CallableStatements? (After clearing my doubts, I may end concluding that the only relevant feature of CallableStatements is their capacity to deal with stored procedure invocations)
According to procedure's precompiled execution plan SQL compilation implies execution plans generation PL/SQL compilation implies P-code generation and, SQL statements (from PLSQL code) are treated no differently by Oracle than SQL from Java or C/C++. These SQLs will be parsed and execution plans for those SQLs created. ... When the PL code executes the SQL statement, only then does the SQL engine receive the SQL, parse it, and create an execution plan for it.
Therefore, even when the stored procedure can be parsed and cached in SGA (through the OracleConnection.preparedCall("proc") invocation), the SQL statements won't be effectively compiled until they are executed, right? And going deeper, will those SQL statements be cached to be reused in future invocations of the containing stored procedure? Is this a characteristic of the regular stored procedure execution in Oracle? or is it due to the CallableStatement "origin"?
There is a requirement in my database that I want to restrict the user from directly running queries on database from third party tools such as pl/sql developer and toad.
There is a utility in SQL product_user_profile through which this can be done but it is only restricted if you run the query through sql plus. If I want to restrict and (give suppose select,insert) to a user for directly running queries through PL/SQL.
I have compiled some procedures, at the time of compilation i saw some warnings & errors but i did not notice, Now can we see that errors or warnings in db console or any other way.
I have a requirement to create a packaged proc which lists down a set of database objects and its statuses whenever the status of objects is changed as valid/invalid in user_objects. Also, those valid objects need to be compiled while running the packaged proc.
I have two same DB schema (same structure, same data) and I need to provide update in one of them when data in the other one is updated. It is singe direction only (we change data in DB Schema A and synchronize data in the DB Schema B; there is not opposite direction). Only small portion of data (compared to the size of DB Schema) might be changed or added this way.
I have table in Oracle with one column PRODUCT. Column PRODUCT have following values -
Account Management Active Directory Adobe Acrobat Reader NT Account Application Security
[code]....
I am designing application where I need to search for PRODUCT based upon user's input. Lets say user wants search on 'Laptop Account Broken'. I want to search for all products which contains any of words in user's input. So based upon user's input I want output like below.
Expected Output:
Account Management NT Account WebSite Account HP Laptop
The Scenario is that we have to restrict clients to write file on C drive for which we have to grant admin privileges(OS) which we don't wanna give. Rather they can write on their own profile.
In CMD we can find their profile with %userprofile% command,but i am confused of using it in oracle form. so is there any possibilities to redirect O/P to userprofileyour_file.txt
Just for an instance ,code is like this which is currently writing in C: drive
i want to find the name of user who make changes in the table structure or create any index or constraint or unique key or alter the column? Is there any way to find in Oracle. in which table what change has been done as well?
following Output needed
userid, username, schemaname, schemachangetime, "what_change_has_been_made", IP address or Computername
Data block 1- master_blk : For date/customer of sale invoice Data block 2- detail_blk1 (detail of the master block - For products and qty) Data block 3- detail_blk2 (detail of DETAIL_BLK1 For entering serial numbers of products)
My requirement is that whatever quantity user enter in data block 2 against each product he must enter equal number of serial numbers of that product in data block 3.
For this I have created on item (cnt_iteml : to count product's serial numbers in block3 ) in data block 2, and on summary item (t_serial_no ) in block3.
Whenever user changes in quantity, cnt_iteml: item is populated with t_serial_no in block3 of that product by following trigger on quantity column.
Following trigger is written on block level at data block-3 to populate cnt_iteml with t_serial_no. PRE-RECORD
IF GET_BLOCK_PROPERTY('SERIAL_NUMBERS',STATUS) IN ('CHANGED') THEN :stock_transactions.cnt_itl:=:serial_numbers.t_serial_no; END IF;
Above triggers are fulfilling my requirement except following condition.
If user after entering serial numbers in block 3 and without saving goes back to block2 and try to navigate to another record he gets a message asking him to save changes by forms. At this time if user presses no then cnt_itl item is not been populated with t_serial_no item's value.
What I want in above condition is that if user was inserting new record cnt_it item should be populated with 0, so that he shouldn't be able to save this record. And If he was updating then cnt_itl item should be populated with actual no of records in database against that product.
I am trying to implement a Houskeeping program for files generated in 4 different servers. This housekeeping program is run as a batch job and I need to use PLSQL to implement it. The files need to be housekept on the basis of the file creation date.
how I can go about doing this using a PLSQL stored procedure.
We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.
In my application i have a requirement as follows.I have 3 tables table1,table2,table3.I have 4 tickets for one license number which is related to client table as follows.
table1 ===== license_nbr(pk) name address =============== ===== ======= LicNo1 test testing
so now the excess paid amount to be adjusted for the remaining tickets through tk2 to tk4.and only tk4 should remain with 400 the balance amount should be updated accordinglyand i have a license number which is a foreignkey of client table. writing a procedure for updating the table2 based on the table3.
I have a schema whereby a table is not joined with other tables.
the info on that table can be gotten manually (by doing a query) and then using that info in another query. so is there a way of getting info from that table?
when i am writing dump from external table, it is accessing records from dump.but when i am trying to access other dumps(create thru expdp) it is giving error.the logic i am following is mentioned below-
CREATE OR REPLACE DIRECTORY "DIR_GMS" AS 'D:Gopal_works est_env_files'
GRANT READ ON DIRECTORY dir_gms TO gopal; GRANT WRITE ON DIRECTORY dir_gms TO gopal;
New point: -- taking export thru expdb expdp hr/hr tables=EMPLOYEES directory=DIR_GMS dumpfile=HR_EMP.dmp logfile=expdpEMP.log then i created one EXTERNAL TABLE TO access it.
i have a table which has 2 columns.1st column has userId and the other contains an xml data as a link.on clicking that link a new file opens containing the data in xml format.
I'm trying to write a procedure that displays customerID, customer name, product name, and the total quantity of products the customer purchased, and the total amount the customer paid.Here's the relevant Schema tables:
Now I'm trying to wrap the above query in procedure code. I believe that I need a cursor, but I don't know what kind of cursor variable to store the result of the SELECT statement in because the query selects columns from several different tables, and I'm not sure how to terminate the FOR loop (but I think probably I can use the EXIT WHEN cursor%NOTFOUND;Here's the procedure code I have written thus far:
CREATE OR REPLACE PROCEDURE find_customer_statistics IS DECLARE TYPE cust_stats IS REF CURSOR; weak ref cursor declaration
SELECT sales_order.customer_id, customer.name, product.description, SUM(line_item.quantity), SUM(line_item.subtotal) FROM sales_order, customer, product, line_item WHERE customer.customer_id = sales_order.customer_id AND line_item.order_id = sales_order.order_id [code]....
