In package head I declare a variable , which reference 'level' type , but I don't know how to declare the variable , because I don't know what type of 'level'.
I have 4 tables , Certain users need to (Select ,insert,delete) certain rows only based on nApplication id
All the tables have Application Id , Based on this application id user will (Select ,insert,delete)
I tried row level security DBMS_RLS.add_policy but it hangs every time when i query the data or when i try to drop the policy. Is there is any method to resolve this issue.
If only Row level security will solve this issue , give me some example
I have a task to update one of the rows in a table (having only 2 columns, number and long) which is long data type. We are on Oracle 10g. Not sure how to use update for a long data type column.
I have tried using dbms_metadata_util.long2varchar, but still not getting what I want.
i've created a schema, which contains 30 tables. the tables are accessed & updated through a web based application. i've made public synonym for all tables for some reasons. how can prevent any one other than application users from updating the tables from Sqlplus.
1. After creating a view, how do I associate that view with certain level of security. As in, only a few users must be allowed to access that view. 2. How can I create a new user-login and password for my database application?
Our client is having requirements that data should be encrypted through-out the process (from transaction level to backup level).
Requirements are as below -
1) Data should be encrypted and can be access only through application (through front end). 2) Even if pl/sql, sql installed, developer user cannot able to fetch data from database. 3) Even DBA, should not have access to fetch the data from the database. 4) Only assigned DBA, should fetch details from database (provided he/she should have details of database as well as application's user / password). 5) It should be restricted by ip and user details (such as ip of application server with user/password of user). 6) Changes should be purely done from database level only.
Now if there is more than one row with same email the one with the latest edit date should be updated with missing fields by using same field value other rows (if the field is present in more than one row, the one with the next latest edit date is to be considered) and the archived status of all rows with same email except this master row must be set to 1.
The Create_Date must be set to the minimum of all the create_date values of rows with same email value The create table would be as follows:
CREATE TABLE student(Id NUMBER PRIMARY KEY,first_name VARCHAR2(30) NOT NULL,last_name VARCHAR2(30) NOT NULL,email VARCHAR2(30) NOT NULL,contact NUMBER,adress1 VARCHAR(30),adress2 VARCHAR(30),city VARCHAR(30),edit_date DATE,create_date DATE,archived CHAR(1))
Sample insert statements would be: insert into student values
I have written trigger to satisfy the requirement, when i write row level it comes out with mutating error on table which is very obvious, i have change it to statement level which is fine but it doesn't satisfy the requirement.
I want to capture the id column , which rows got inserted or updated .
Is there any way to get the newly inserted or updated rows as in case of row level i can get it form :new.id.
I have a table which has plenty of rows. In production, I would estimate it to be from 30 millions to 300 millions. I need to update on column (flag) in all the rows (created before certain date).Now saying just:
UPDATE MyTable SET flag = 3 WHERE created < to_date('2010-10-08 23:59:59', 'YY-MM-DD HH24:MI:SS'); COMMIT;
Does not seem like a good idea - the commit-buffer would become too big.I will write a PL/SQL script for this. The question is, whether I should:
a) Update each row separately, and commit after every 10000 rows. ( WHERE RowId = [rowId] ) b) Update 10000 rows with set of dates ( WHERE rowId > [some_row_id] AND RowId < [some_row_id_2]
In the latter example the some_row_ids would naturally be fetched. The rowIds come from sequence. So which one would be more effective?I am not too familiar with PL/SQL or Oracle for that matter.
I have a table A, whose table structure is in the below format.
Table A
ID DESC VALUE 123 A 454 123 B 1111 123 C 111 123 D 222 124 A 123 124 B 1 124 C 111 124 D 44
Now i need to insert the data from this table to another table B, the sturcture of which is as below
Table B
ID A B C D 1234541111111222 124123111144
How do i frame a query to fetch data from table A and insert that into table B? I don't want to use max and decode combination. as it would return only single row for an ID. I need all the id's to be displayed.
I have a set of rows based on a complex view from multiple table.
I will be updating some of its columns from front-end . Is there any possible ways to lock those rows of data while updating and no other users can update it;
I need to find the identical rows in the below table based on ID column and update the previous identical record's end_date with latest record's start_date-1.
I have two tables eim_asset and eim_asset1.I want to update the table eim_asset1 using the following update SQL (Or Logic)
update eim_asset1 set emp_emp_login = (select login from s_user where row_id in (select row_id from s_emp_per where row_id in (select pr_emp_id from s_postn where row_id in (select position_id from s_accnt_postn where ou_ext_id in (select row_id from s_org_ext where row_id in (select owner_accnt_id from s_asset where owner_accnt_id is not null)))))
It gives me the ORA error : ORA-01427:single-row subquery returns more than one row.know why I am getting it, because of the one-to-many relationship between owner accounts and their assets.
My question is, if I define an object type (create type ... as object ...) is it possible to hold a variable of this type as the session level? For example, if I am creating an order using multiple web pages, it would be much easier (and intuitive) to create and manipulate an order object than to hold the data in generic collections.
If that is not possible, is there some way to make a generic Apex collection appear more application specific? By this I mean some way to map the columns C001, C002, ... to more intuitive names such as CUST_NO and ORDER_DATE. I had considered possibly creating a view of the APEX_COLLECTIONS view which would rename the columns but then I would also have to create a bunch of instead of triggers if I wanted to update it as well.
i have to display the 10 most costly missions. but if the 11th record has the same cost then it needs to display 11 records instead of 10. how can i do this?
mission_id, mission_type_id, security_level and code_name.
What i have to do is get the 10 most recent missions and change their security level to the highest one in their mission_type_id but ONLY if code_name length is >7
So far I have this, the problem is that the oracle moans about the order and wants me to close the bracket before the order
sql
UPDATE missions m SET m.security_level = ( SELECT max(m2.security_level) FROM missions m2 WHERE m2.mission_type_id = m.mission_type_id AND length(m2.code_name) > 7 ) WHERE m.mission_ID IN ( Select m3.mission_id From missions m3 ORDER BY m3.mission_id desc)
My solution to the following question update 10 rows. It should update only 6 records. Create a copy of the missions table called AM_X_442_2. For missions on this table that meet the following criteria:
1. within the 10 most recent missions 2. length of the first word of the mission code_name exceeds 7 characters
Change the security level to the highest security level found in missions of the same type.
UPDATE AM_X_442_2 am SET am.SECURITY_LEVEL = ( SELECT MAX(amx.SECURITY_LEVEL) FROM AM_X_442_2 am INNER JOIN AM_X_442_2 amx [code]....
I need encrypt column in the table (TDE) with 160 rows (PK) i'd like know what impact if i rn in time production this procedure. And as will be behavior the oracle database if this column is FK.
I want to write a sql query which will fetch the data from manual_temp_master and manual_temp_detl.But from manual_temp_detl table, Price_bkt_cds columns should be displayed as columns. Like the should look like as below:
what is the difference on DBMS_STATS for table level and partition level , which will provide the best optimizer . If the table xxxx is partitioned from 1 to 10 ,then running gather stats on table xxxx as whole table level or partition level which will provide best result on the performance.
doc_id 100 was excluded because it has a higher version which was shown instead.
So how would i express this is oracle sql.
edit: Just thought i should say that I have been tring to crack this for 2 days now :P I have been messing around with MAX() but I cant make it do what i want.
I've a large table on which I applying aggregate and group by functions to the the results.
Here are two of the columns in my table:
Name ==== Score John ==== 200* Zohaib ==== 299 Ali ==== 0* John ==== 200 Maria ==== 150* Ali ==== 0 Maria ==== absent John ==== absent
Here astrick (*) means with distinction....
The "score" column is a varchar column I want to run a query on this table to show the highest score for each student and the output should be like this:
Name ==== Score Zohaib ==== 299 John ==== 200* Maria ==== 150* Ali ==== 0*
Important note:
1. if there is a tie between two highest scores like for a student, incase of john 200 was made twice, but the score with asterick (*) will be the "maximum" becuase it is with distinction so the output should also show the the highest score with asterick.
2. the output should show the the 2nd column (score) in desc order of highest score by each student...again incase of a tie, the one with astrick will come first in the result..
I know with just mere numbers, that is pretty easy but in this case it is a varchar column and also i need the astrick along with the highest score.
I want the simplest and shortest query if possible to achieve this result
I hope I've been able to clearly explain my requirment. I am using 10G.
