SQL & PL/SQL :: Cursor Select Statement?
Apr 28, 2010
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.

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 ?

1) SQL Statements are not using IMPLICIT CURSORS.
2) Only the SQL statements of the PLSQL program create implicit cursors.

I would like to mention that I won't be able to give the data,specific information(like query or table names) about the issue as this concerns the privacy of some multinational company(where I work).
We have windows server and we are currently using Oracle 10g.
Issue-
We have a ProC, which has a SQL statement where it is trying to OPEN a cursor. The cursor query is huge and fetches data from 3 tables. 3 tables have 5k, 600k and 1.7 millions records respectively but the 'where' condition in cursor query makes the total count to 3k lines only.
Now the problem is , we have a schedule reboot of the server every Saturday night and the next day(Sunday night) when the program runs it gets stuck in the query --> OPEN <cursor> . We wait for 5 hours but this OPEN cursor query never executes or completes, that means our program gets stuck here.Eventually we have to kill the program.We have tried running it after killing as well but it again gets stuck.
Now the interesting part. On Monday business happens as usual but in the night when we again run this program it runs within minutes. The records in the tables are more or less same. Open cursor does not get stuck at all. It runs every night properly but every Sunday night it gets stuck. note that the program does not run on Saturday nights. So on Sunday night it runs for the first time after server reboot.
So there is something with Open cursor statement(with so much data) after server reboot. What exactly Open cursor does in memory or database.

I have a DML Statement inside a procedure and i use a cursor variable to get the values checked as below . I have attached my procedure not completely but the declaration part and the DML statement part.
The issue is my procedure is not inserting the records at all. It selects the values and then inserts accoringly but its not selecting because of the cursor reference R_LOC.LOCATION_GID.
when i hard code the value in the DML statemnt for the R_LOC.LOCATION_GID, the rows are inserted as expected. So i guess the way the procedure executes the value is not correct.
Modifying my select part which uses cursor variable R_LOC.LOCATION_GID under Insert statement.
select d.servprov_gid, d.depot_gid, replace(d.appointment_time,'':'') appmt_time, d.'||v_day_to_use||' DayUsed
from tesco_fresh_templates t, tesco_fresh_templates_d d, location_refnum r
where t.set_id= d.set_id
and d.depot_gid=r.location_gid
AND D.SERVPROV_GID=''R_LOC.LOCATION_GID''
and r.location_refnum_qual_gid=''TESCO.IVS SCHEDULING''
and (r.location_refnum_value=''YES'' or r.location_refnum_value=''Y'')
and t.default_set=''Y''

I am not an Oracle programmer but I have been given a task to produce a number of Text files from an Oracle table based on a selection from the table itself.The table consists of many records with a currency code and I need to extract the data into named files based on the currency code.My first idea was to use Cursors and try a select statement matching on the returned value of the cursor but no Joy I can't make it work - perhaps I need to take a new approach.
Current / latest attempt below
DECLARE
CURSOR tmp_splitter_cur IS
SELECT DISTINCT end_consumer_country
FROM tmp_splitter
WHERE 1 = 1;
currency_rec tmp_splitter_cur%ROWTYPE;

I've create two types:
create or replace type VAL_REC as object
(WAARDE number(20,5) ) ;
create or replace type VAL_TAB is VARRAY(200) of VALREC ;
create or replace type WSN_REC as object
( START_DATE date
, END_DATE date
, DATA VAL_TAB) ;
create or replace type WSN_TAB as table of WSN_REC ;
In a PL/SQL table collecton WSN_TAB is filled. Now I want to create a query (ref cursor) that gives the result:
START_DATE END_DATE WAARDE(1) WAARDE(2) WAARDE(3) etc.
2010-08-15 2010-08-16 20 20 40

SELECT
contgrp_num,
cpgrp_desc,
strategy_id,
perftyp_cd,
stiertyp_id_calcbase,
stiertyp_id,
cpgrp_flg_aggr,
pgrptyp_cd
[Code]..
The above query is not returning any value. But, when I put this within a begin-end block, its fetching data.
why its not returning any data without the begin-end block.
The entire code has an outer begin-end block within which the cursor is also defined.

I've been examining som old queries in an existing db due to more and more problems regarding performance. The sql is used as backend for a java/jboss web application with the possibility for users to enter data. With more and more data, there starting to come complaints about the performance.
I stumbled upon a select query with an embedded cursor similar to this :
select id, name ...,
cursor(select id, sequence.... from table2),
cursor(select id, name.... from table3)
from table1
join table4 on (table1.id = table4.id)
where .....
The javacode is a prepared statement with the actual sql as a string and the content of the cursors saved in conjunction with each row.
when i use sqldeveloper to show the explain plan without the cursors, the cost is 2428
when i use sqldeveloper to show the explain plan with just 1 of the cursors, the cost is ~165000
Is there a better way to do this instead of cursors ?

I am trying to insert 100K rows, I have written this proc using cursor. But it is saying anonymous block completed, and no rows are inserted. If I just run the select it returns the rows.Could if just insert into select would be fine or should I use cursor.
CREATE OR replace PROCEDURE Insert_data (l_from_date IN VARCHAR2,
l_to_date IN VARCHAR2)
IS
lc_err_msg VARCHAR2 (2000);
ln_count NUMBER := 0;
CURSOR ins_d IS

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 two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
[code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.

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.

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.

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)

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.
