In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO
AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
SELECT
DNO,
BNO,
c2,
c3,

I 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 ?
Why Blind select is better than Conditional select Statement?
View 10 Replies View RelatedI have two tables have almost the same columns, how can I use merge statement to update the target table only when there is difference between source and target table. Is there any easier way not compare each column one by one? I am using Oracle 11.2
Here is the MERGE statement:
Merge into tb_trgt trgt using tb_src src
on (src.id = trgt.id)
when not matched then insert (trgt.id, trgt.nm, trgt.addr) values (src.id, src.nm, src.nm)
when matched then update set trgt.nm = src.nm, trgt.addr = src.addr
where trgt.nm <> src.nm or trgt.addr <> src.addr
;
Is there any easier way to specify the where clause in the NOT MATCHED? I don't want compare each column of the tables. Since I may have many columns in the tables.
what is the difference between after or before insert in row level trigger and statement level trigger.

I have a table with around 80 columns. All i need is to select first 40 columns.
Is there any way to select first 40 columns without giving all the 40 Column Names in select clause.
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 ?

I have a quite complex view that selects from approx 10 long tables (approx 4M records each) and build one "customer sentence" pre customer id. I will be always getting just one row from this view, eg. select * from my_view where party_id = XYZ. I'll NEVER EVER select the whole view.
The problem is that running a query:
select * from my_view where party_id = XYZ takes really long time, while putting the party_id = XYZ condition directly into the view executes in 0.0 seconds.
After putting a ORDERED FIRST_ROWS(1) hint into a view the execution plans seems to be the same (or very similar) for both queries. Unfortunately, I can not transfer anything but screenshot from the environmnet - therefore I paste the exec plans as screenshots only - pls follow the link: [URL]...

Calculating the difference between the two rows of same columns? Example of my Scenario is as follows
I have a table as shown below, there are checks thats has been issued per week (to tell how its been issued per week ,if you see the week number ,there is a change in week no for period of 7 days i.e. what i have to show on my results tables based on week no and probably we may need to take into account for check no too.)
wekno ! checkno ! end date
------ ! ------ ! ------
1 ! 1 ! 1/7/2012
1 ! 2 ! 1/8/2012
1 ! 3 !1/9/2012
2 ! 1 ! 1/14/2012
2 ! 2 ! 1/15/2012
3 ! 1 ! 1/21/2012
result table and date range i picked up was 1/1/2012-1/31/2012
wekno ! checkno ! end date ! previous period ! Daysin period
------ ! ------ ! ------ ! ------------- ! ------------
1 ! 1 ! 1/7/2012 ! null (as previous period is 2011 and so prvs year i dont count) ! 7 this because we see change in wkno per 7 days
1 ! 2 ! 1/8/2012 !null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
1 ! 3 ! 1/9/2012 ! null becoz this one falls same week and therefore previous peroid would be the same as above ! 7 above reason
2 ! 1 ! 1/14/2012 ! 1/7/2012 becoz this a second week as you see the change in wekno and therefore its previosu period is 1/7/2012 ! 7 above reason
2 ! 2 ! 1/15/2012 ! 1/7/2012 becoz this check falls on the same second week so previosu would be 1/7/2012 ! 7 above reason
3 ! 1 ! 1/21/2012 ! 1/14/2012 as a new week no starts this gonn be 1/4/2012 ! 7 above reason
I 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.
decode (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
how to set the timing on for all SELECT statements in a procudeure...and i want that should come as a output for very SELECT statement slong with my original output.
View 6 Replies View RelatedI 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?
I'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.
FROM
S_ORG_EXT
where
Location = 'North America' and LEVEL ='Software'
OR location = 'North America'
and Active = 'N'
I 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.
Below is the query that I have:
Quote:
select a.contact, b.db_name
from MOM.db_contacts@DB_LINK a, MOM.databases@DB_LINK b,
where a.DB_ID=b.DB_ID
and b.DB_name=(SELECT unique substr(upper(t.target_name), 1, instr(t.target_name,'_',1,1)-1)
FROM mgmt_targets t JOIN mgmt_current_severity s
ON s.target_guid = t.target_guid
WHERE t.target_type = 'oracle_database'
and UPPER(t.target_name) like '%11GDB%');
How can I add two more columns into the select statement and the two columns are in the tables that were in the sub query..I would like to have something like this:
Quote:
select a.contact, b.db_name, COLUM1, COLUMN2
from MOM.db_contacts@DB_LINK a, MOM.databases@DB_LINK b, mgmt_targets t, mgmt_current_severity s

ON s.target_guid = t.target_guid
WHERE t.target_type = 'oracle_database'
and UPPER(t.target_name) like '%11GDB%');
I have a cursor in a procedure that selects columns from a table on a remote Oracle database using a database link. It all works fine when the table name and database link name is 'hard coded' into the procedure but what I would like to achieve is have the select statement lookup the table name and database link name from a column in another table. See example below
CURSOR c_total_bookings IS
SELECT personnel_id,
surname,
forenames,
birth_date,
[code]...
What I would like to do is replacecompany_bookings@remote.linkwith a variable that takes its value from another table.
select GAM.FORACID,
SOL.SOL_DESC,
GAM.ACCT_NAME,
LHT.LIM_SANCT_DATE,
LHT.SANCT_LIM,

it is not returning any output. I have hardcoded the table name here where as in real time Mytable name will differ.
I was given a SQL query to develop another query that will need to do something similar. The query I was given I believe is a stored procedure. It is PL/SQL and has a SELECT statement that looks like
SELECT :var1 AS var1
FROM t1
WHERE
:var1 = 1
In the past I have seen where variables can be used in the WHERE clause like
SELECT c1
FROM t1
WHERE
c1 = :my_column_valueand this makes sense to me.
Usually :my_column_value is declared in the DECLARE block of the PL/SQL. In the query I was given, :my_column_value is not declared in any DECLARE blocks (maybe I wasn't given the entire code??). But even if it was, that would be even more confusing because in the DECLARE block it could be assigned one value and then set to another value in the WHERE clause???
The first query doesn't make sense to me and when I run it as plain SQL I get an error like "SP2-0552: Bind variable "var1" not declared. I am guessing that such a syntax is not valid for regular SQL?
The only thing I can gather that the first query does is something along the lines of
SELECT 1 as var1
so it will output a 1 for every row. Not always that interesting of a query, but it is needed sometimes, I know. But I still don't understand this type of assignment.
So what's going on here? I'd be happy to look it up and read about it myself, but I don't know what to search for.
i want a select statement to retrieve the last name added into the "ename" column .i mean :if i insert "jack" into "ename" column , i want to write a select statement to retrieve that last name while i do not know it is jack or any other name ?

View 11 Replies View RelatedI am trying to find the best solution for the following problem
I have a table called HIERARCHY with 3 columns.
col1 col2 col3
------------------------
1
1 2
1 2 3
4 5
6 7 8
I would like to check if the table contains invalid records. Col1 , Col2 and Col3 are seen as hierarchy levels and col1 is the top level.
For instance record 1,2,3 (level3) is valid because it exists record 1,2 (level 2). Moreover 1,2 record (level 2) is valid because it exists record 1 (top level).
However 4,5 and 6,7,8 are not valid as higher levels are not completed.
How can I check in a single SELECT statement if the table contains invalid records? Maybe analitical functions or regular expressions?!
