Jul 25, 2010I have a problem that i have hard coded the username.tablename in each select statement of all forms of my application. Now i want to use a dynamic variable in place of username in each select statement throughout the application. The example is:
select * from scott.emp
and i want to write it as:
select * from variable.emp
But at compilation of the form the compiler should know the above variable name.
I have tried to use following select statement but it does not work.
select user into :global.username from user_users
I think perhaps my problem would be solved with Dynamic SQL Statement but i have no experience by using this statement.

Security :: VPD Function For Column Masking With Inner-select?
Sep 12, 2013I'm writing a VPD function to be used for column masking. The predicate (WHERE-clause) it generates may take many different forms. In particular, it may contain inner-selects; for example,
"exists(select '*' from B where B.VAL = '123' and A.KEY = B.KEY)"
where A is the table that is associated to the VPD function, and B is some other table.
if this is OK for column masking? If not, my VPD function may sometimes work and sometimes fail, in unexpected ways.
The Oracle Database Security Guide (11g Release 1) says
Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates".
This seems to indicate that there are cases where a VPD function works for row-level security, but not for column masking.
an example of a 'regular Oracle VPD predicate' that doesn't work for column-masking?

PL/SQL :: How To Use Column Names Generated From Dynamic SQL
Feb 8, 2013I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
[Code]...

Dynamic SQL With Select Update For
Jun 21, 2012I wrote a simple procedure to copy the create timestamp and create user name to update timestamp and update user name of the same record. (See code below)
This works fine for a hard-coded table and primary key column. However, I cannot figure out how to get this to work with dynamic sql.
All my other procs, which don't use SELECT UPDATE FOR work fine with dynamic sql.
Proc that works:
CODECREATE OR REPLACE PROCEDURE proc_set_upd_columns
IS
CURSOR c1 IS
SELECT *
FROM mytable
FOR UPDATE
ORDER BY mycolumn;
c1rec c1%ROWTYPE;
[code].........
Partial proc that does NOT work:
CODECREATE OR REPLACE PROCEDURE LDEVORE.proc_set_upd_columns (
p_input_table_name IN VARCHAR2,
p_pk_id_col_name IN VARCHAR2)
IS
v_qry_str VARCHAR2(1000);

v_create_tmstmp TIMESTAMP;

SQL & PL/SQL :: SELECT From Dynamic Table Name?

But when I compile this I get ORA-00936 : Missing expression at the EXECUTE IMMEDIATE line.
SQL & PL/SQL :: Dynamic Block Vs SQL SELECT?
Oct 19, 2011I have a question regarding the optimal way to code a dynamic SELECT INTO statement. Below are the 2 posiibilities I know of:
1. Dynamically executing the SELECT statement and making use of the INTO clause of the EXECUTE IMMEDIATE
statement
CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2)
RETURN NUMBER
IS
v_query_str VARCHAR2(1000);
[code]...
2. Encapsulating the SELECT INTO statement in a block and dynamically exectuting the block
CREATE OR REPLACE FUNCTION get_num_of_employees (p_loc VARCHAR2, p_job VARCHAR2)
RETURN NUMBER
IS
v_query_str VARCHAR2(1000);
[code]...
which way would be preferred? I know the second method uses a bind variable for the INTO clause, but does the first one also use bind varialbes (no semi-colon)? Any differences in terms of efficiency or speed?
SQL & PL/SQL :: Select Statement Is Blocking A Delete Statement
Jan 11, 2012I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 || ' User '||s1.username || '@' || s1.machine
3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text
||' is blocking the SQL statement on '|| s2.username || '@'
4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> '
6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 ,
7 v$session s2,v$sql sqlt1, v$sql sqlt2
8 WHERE s1.sid =l1.sid
9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id
AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1
10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2;
[code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?
If Statement In Select?
Mar 22, 2013 simply select and works great:
select 'CARAT Issue Open' issue_comment, i.issue_id, i.issue_status, i.issue_title, i.ISSUE_summary ,i.issue_description, i.severity,gcrs.Area_name, gcrs.sector_name,
substr(gcrs.stream_name,1,case when instr(gcrs.stream_name,' (')=0 then 100 else instr(gcrs.stream_name,' (')-1 end) ISSUE_DIVISION,
case when gcrs.STREAM_NAME like 'NON-GT%' THEN 'NON-GT' ELSE gcrs.STREAM_NAME END as ISSUE_DIVISION_2
from table(f_carat_issues_as_of('31/MAR/2013')) i inner join v_gcrs_with_stream gcrs on i.segment_id = gcrs.segment_id
where UPPER(ISSUE_STATUS) like '%OPEN%'
Now I want to callte two columns:ISSUE_DIVISION and ISSUE_DIVISION_2
if they are equal in new columns should be value 1 if are not equal should be 0,how can I do it ?
Select Statement Errors
May 5, 2010I have a question about select statements, as I am new to them and don't know how to work all the commands yet.
I'm making a select statement that is about half right... it is shown below:
select t.warehouse_id,
t.quantity_on_hand,
c.product_name
from pahtest3.inventories t
join pahtest3.product_information c using (product_id)
WHERE warehouse_id in (7);
I need to take this select statement and make it so it shows all the products that don't have any quantities in the warehouse in addition to the ones that are already being shown in that select statement.
Format Of Select Statement
Jun 15, 2007decode (a.cancel_time,'',sum ((to_date('23:59','hh24:mi') - a.alarm_time)*24*60), sum((a.cancel_time - a.alarm_time)*24*60)) Duration,
After executing this statement. I get negative values if cancel time is null
I want to subtract alarm_time by 24 hours, if cancel time is null. If not null then cancel-time - alarm_time

Sep 1, 2011I have a need to use the Alias name of a column within the same select statement( because I can't have another select statement using the first select as table - BO tool limitation).
Ex:

Currently oracle won't allow using alias name Sum_qty in the same select statement. Is there a way to use alias within the same select statement?
SQL & PL/SQL :: Variable In Select Statement
Jul 5, 2011I'm trying to write a simple query so I can do some testing on my application. I am trying to do something like this:
SELECT
Location,
LEVEL,
FROM
S_ORG_EXT
where
Location = 'North America' and LEVEL ='Software'
OR location = 'North America'
and Active = 'N'
in the where statement, I have put in the 'Active' that isn't a column. I want to be able to be able to change that in the select part. But I am not able to do so.
this is what I have tried:
SELECT
Location,
LEVEL,
Active = 'N' --I want to change this in the to N or Y so I can get different results.

Location = 'North America' and LEVEL ='Software'

SQL & PL/SQL :: Select In Case Statement
Feb 11, 2011I have the following tables:
create table lookups (code varchar2(20), amount number);
insert into lookups values ('Rent' , 500);
insert into lookups values ('Breakpoint' , 10);
create table products (id number, cost number, year varchar2(4));
insert into products values (1, 1000, '2011');
insert into products values (1, 2000, '2011');
insert into products values (2, 100, '2011');
insert into products values (3, 50, '2011');
commit;
I want to write a query which lists the IDs and the sum(cost), and a Y/N indicator which is set to 'Y' IF sum(cost) > ( (lookups.rent value) * (100 - lookups.breakpoint value))/100
I have written this query:
SELECT id,
sum(cost)cost,
year,
CASE
WHEN cost >
((SELECT amount
[code]....... ORDER BY id;
This returns
ID COST YEAR YN
--------- ---------- ---- -
1 1000 2011 Y
1 2000 2011 Y
2 100 2011 N
3 50 2011 N
The YN is correct, but it needs to sum the amounts. So there should only be one row for id1 = 3000.e.g.
ID COST YEAR YN
--------- ---------- ---- -
1 3000 2011 Y
2 100 2011 N
3 50 2011 N
I am not sure how to do this. Or is there a better way of doing this than using CASE.
