SQL & PL/SQL :: How To Add Two More Columns Into Select Statement
May 6, 2011
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
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%');

I have a table which stores Employees and their Phone numbers. Each employee can have multiple numbers e.g.
Employee, Number
Adam, 123
Adam, 456
John, 123
John, 456
I am trying to write a select statement that will split the rows into columns and group by each employee e.g.
Employee, Number1, Number 2
Adam, 123, 456
John, 123, 456

I am student of Oracle programming(SQL).Has a question on MIN and MAX functions:
- "Write a SELECT statement that returns one row for each customer with four columns--the customer's first and last name, the date of the customer's most recent order, and the date of the customer's oldest order and the difference between the two dates. Sort the result set so the customers who have been ordering with the company the longest appear first. Use most recent order date as a tie-breaker for the sort."
where orders and order_details,customers are 3 different.this is my query ...but its not working.
SELECT DISTINCT customers.customer_first_name||' '||customers.customer_last_name AS Customer_name,MAX(order_date) AS "Most recent order", MIN(order_date) AS "Oldest order"
FROM customers
INNER JOIN orders
ON customers.customer_id=orders.customer_id
LEFT JOIN order_details
ON orders.order_id=order_details.order_id
LEFT JOIN items
ON order_details.item_id=items.item_id
ORDER BY Customer_name

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,
c4,
c5,
c6,
c7
[code]....

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 ?

I have 8 columns. Some of them might be null.I want to display all 8 columns in my result. Not null columns will be first and null at the end.Here is a sample data :
Employee table :
Employee_id Emp_fname emp_lname emp_mname dept salary emp_height emp_weight
1 aaa ddd d1 100 6 180

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 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

I 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:
Select dept_id, agency, sum(quantity) as "sum_qty"
where sum_qty > 500;
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.

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.

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 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?!

I've read so many different pages on this topic but I can't seem to get my query the way it needs to be. Here's the query:
select admitnbr, lastname||', '||firstname||' '||finitial, hphone, mobile, wphone, med_rec, dob
from patients join schedule using (key_patien)
join adtmirro using (key_patien)
where appt_state = 'ON HOLD'
Because patients in my database can have multiple appointments "on hold" there are duplicates in the results. I only need 1 record per patient in order to forward this information into an automated dialer to contact that patient. I do NOT want to call the patient over and over again. Once will suffice. I'm trying to make a distinction on the column 'med_rec'. One row per 'med_rec' will be awesome but I can't find a way to create a distinct on that column.

here is what i am trying to do: im as using oracle 8 with sqltool
i have a Very large query. and i notice that many things are repeating. so i want to add them to a variable, instead of re-typing them. for example:
select SomeID from SomeTable;
i want SomeID to be put into a variable. but i still want to be able to get a normal select query at the end so that i can see the returned value:
i tried things like:
declare x number;
begin
set x=45454
select x from SomeTable;
end;
but could not get it to work.

I can work with 'straight' query's etc., but now I want to make a query with a loop. I have made a simple one to demonstrate what I want but the real one is working is working by it self but I want to get it work with a loop.
This is the simpel version:
DECLARE
P_UID NUMBER;
Max_UID NUMBER := 42220;
BEGIN
P_UID := 42210;
LOOP
select *
from contract lc
where lc.UIDCONTRACT = P_UID;
P_UID := P_UID + 1;
EXIT WHEN P_UID > Max_UID;
END LOOP;
END;
The error I get is:
Line 10, column 9:
PLS-00428: an INTO clause is expected in this SELECT Statement.
So I know you can declare a variable and then CONTRACTID INTO v_contractID.
But if I have to put every field in a variable what is then the advantage of a loop. So I expect that I'm on the wrong road and not understand how this works.
