PL/SQL help on Varray

Hi All,
I have a PL/SQL stored procedure with close to 20+ arguments, many of which are optional in between. Hence
the procedure call involve many of the arguments which are null. for e.g
procedureName(arg1,arg2....arg20)
Call procedureName(1, 2, null, null, 3, 4, null...)
Instead of the above approach, I am planning to send two Varray as argument which specify key and value respectively. This would help me to only send argument which are not null and also would help me to dynamically add additional 'where clause' with out changing the PL/SQL procedure.
I am wondering about the usage of Varray from a performance perspective and also as a industry practice.
Any assistance will be of great help.

By key and value, I am assuming that you mean parameter name and value for that paramter. If that is correct, then, depending on where you are calling this from and how you are calling it, I would be tempted to go the named parameter route as Karthik suggested.
If you want to go with the array approach, I would do it with a single array of records (created in PL/SQL) or objects (created in SQL). The main advantage of using an array of objects is that, because they are database objects, they can usually be used by calling code in other languages, nt just PL/SQL.
Something like:
SQL> CREATE TYPE param_tp AS OBJECT (
2 param_name VARCHAR2(30),
3 param_value VARCHAR2(50));
4 /
Type created.
SQL> CREATE TYPE param_tbl AS TABLE OF param_tp;
2 /
Type created.If you go this route, you will need to check carefully in your procedure to make sure that the values passed as parameters can actually be converted to the correct type to match the original parameter types. If you will be passing dates, you will also need to ensure that all callers are aware of the specific date string format you will be expecting so that you will not have conversion issues.

Help with VARRAY in PL/SQL

I wrote the below Stored Procedure in a package. I am not able to execute this, can anyone please help
Package Definition:
CREATE OR REPLACE PACKAGE "CDS_SUBLIMIT_TYPE_PKG" as
TYPE COLLATERAL_ARRAY is VARRAY(100) OF NUMBER(29);
procedure get_original_balance_array_p(in_collateral_id IN NUMBER, l_data OUT COLLATERAL_ARRAY );
end CDS_SUBLIMIT_TYPE_PKG;
Package Body:
CREATE OR REPLACE PACKAGE BODY "CDS_SUBLIMIT_TYPE_PKG" as
procedure get_original_balance_array_p
(in_collateral_id IN NUMBER, l_data OUT COLLATERAL_ARRAY ) IS
CURSOR c_collateral IS
SELECT collateral_id FROM collateral where rownum < 10;
BEGIN
l_data:=COLLATERAL_ARRAY();
FOR collateral_rec IN c_collateral LOOP
l_data.extend;
l_data(l_data.count):=collateral_rec.collateral_id;
END LOOP;
l_data.extend;
l_data(l_data.count):=in_collateral_id;
END get_original_balance_array_p;

CDS_SUBLIMIT_TYPE_PKG.get_original_balance_array_p(collateral_id, collectionId);
end;

collectionId collateral_array;You missed out the package name - it should be
collectionId cds_sublimit_type_pkg.collateral_array;VARRAYs are good as multivalue columns in database tables, if you're into that (I'm not particularly). In PL/SQL code, nested tables have more functionality, especially in 10g.

XML - PL/SQL help

Hello,
I am having a query as a part of my procedure block that extracts the following xml and stores it into a variable that is of xmltype:
<FeatureRoot>
<Feature>
<FeatureName>qaz</FeatureName>
<FeatureAction>Add</FeatureName>
</Feature>
<Feature>
<FeatureName>wsx</FeatureName>
<FeatureAction>Remove</FeatureAction>
</Feature>
</FeatureRoot>
Now what i want to do is loop through this variable (which is of xmltype) and print the values of the tags <FeatureName> and <FeatureAction> for every Feature.
(ie)
qaz Add
wsx Remove
Can you please tell me how i can loop through to extract the values?
Many Thanks,
Kalyani

Hello,
Thank you. The solutions may hold good on a normal context. What my problem is I want to run a loop through an anonymous block in pl/sql where I am already using a cursor where each record contains an xml value as above. So i need to be extracting for each run in a cursor. So i need to be extracting the <FeatureName> and <featureaction> values in each cursor run. Any help on this?
ThanksCan you not incorporate it as part of the cursor itself?
It can return the values as part of the data from the cursor rather than using PL/SQL extracts on the XML to do it.

Hi,
Here's how you can do it in Oracle 8.1.
To get the individual sub-strings from product_lines, join your current result set to this "counter table"
(   SELECT ROWNUM AS n
    FROM    all_objects
    WHERE   ROWNUM <= 10 -- upper bound on number of items
) cntrIf you don't know the worst case of how many items might be in product_lines, it's a little more complicated:
(   SELECT ROWNUM AS n
    FROM    all_objects
    WHERE   ROWNUM <= 1 +
            SELECT MAX ( LENGTH (product_lines)
                        - LENGTH (REPLACE (product_lines, ','))
            FROM    table_name
) cntrJoin this to the existing result set like this
WHERE   ...
AND     INSTR ( product_lines || ','    -- one extra comma added
              , 1
              , n
              ) > 0When you do the join, you will have
one copy of all the rows with one item in producgt_lines,
two copies of all the rows with two items in producgt_lines,
three copies of all the rows with three items in producgt_lines,
and so on.
When a row has been copied, each copy will have a different value of cntr.n.
To extract the n-th substring from product_lines:
SELECT ...
        SUBSTR ( product_lines
               , INSTR ( ',' || product_lines,   ',',   1,   n)
               , ( INSTR (product_lines || ',',   ',',   1,   n)
                 - INSTR (',' || product_lines,   ',',   1,   n)
               ) AS product_lines_itemWhen you have derived this column, you can join to the table with the translations
WHERE TO_NUMBER (product_lines_item) = propertyidTo combine these rows into one row with a comma-delimited list, GROUP BY all the columns you want to select except the property_value ('produc 1', 'tangerine', etv.), and SELECT:
LTRIM ( MAX (CASE WHEN n = 1 THEN ',' || property_value END) ||
        MAX (CASE WHEN n = 2 THEN ',' || property_value END) ||
        MAX (CASE WHEN n = 10 THEN ',' || property_value END)
      )I don't know a good way to re-combine the rows in Oracle 8 without assuming some limit on the number of items. I assumed there would never be more than 10 in the example above. You can say 20 or 100, I suppose, if you want to. If you guess too high, everything will still work: the query will just be slower.
This is a just one example of why packing several values into a single column is a bad idea.

SQL help: Selecting tickets with no open tasks

I'm new to SQL. I need your help in a script where I need to fetch the tickets with no open tasks.
Say, following is the Task table

SQL HELP , URGENT PLEASE

Hi,
I want some help in writing a SQL Query .Its besically a hierarchical query. Let me lay down the table structure first to explain my requirements better.
PORP_TABLE(NODE_LEVEL int, WBS_ID int, WBS_NUMBER varchar(60), LFT int,RGT int)
SELECT NODE_LEVEL, WBS_ID, LFT,RGT FROM PROPOSAL_WBS PW WHERE PROPOSAL_REV_ID = 7000
(SAMPLE DATA)
NODE WBS
LEVEL WBS_ID NUMBER LFT RGT
0 7055 ROOT 1 24
1 7056 1 2 5
1 7088 2 6 9
2 7057 1.1 3 4
2 7089 2.1 7 8
2 7091 3.1 11 14
2 7103 3.2 15 16
2 7105 4.1 19 20
1 7090 3 10 17
3 7092 3.1.1 12 13
1 7104 4 18 23
2 7106 4.2 21 22
ALLOCATION_DETAIL( WBS_ID int, COST_ID int, PERIOD Date, AMOUNT Float)
sample data
WBS_ID , COST_ID , PERIOD , AMOUNT
7057 100 01-jan-2005 5000
7057 100 01-feb-2005 2000
7057 100 01-mar-2005 1000
7057 100 01-apr-2005 6000
7057 100 01-may-2005 3000
7057 100 01-jun-2005 45000
7106 100 01-mar-2005 8000
7106 100 01-apr-2005 7000
7106 100 01-may-2005 9000
Now the PORP_TABLE has got the parents and childs. Only the leaf nodes in the hierarchy has the values stored in the ALLOCATION_DETAIL table. Now here is the scenario
In the example 7055 is the root WBS . The Leaf WBS are the one with max extension in the wbs number ( in this case it is 1.1, 2.1, 3.1.1, 3.2, 4.1 and 4.2)
Now the Starting period for each leaf node in the ALLOCATION_TABLE could be differrent . What that means is WBS 1.1 could start in Jan -2003 and WBS 3.1 Could be Jul-2005 . So the ending perios are also differrent for differrent WBS . Some can span 2 years some can 5 years.
So how to write a query so it retrieves the value for all the Wbs starting from the MIN ( PERIOD ) upto the MAX(PERIOD), and it should roll up also. Now there is No connect by Prior or any analytic functions available for this . THIS NEEDS TO BE DONE ONLY THROUGH TRADITIONAL SQL STATEMENT . And NO DB FUNCTIONS CAN BE USED .
Now if the WBS is a parent node then it should have the sum of all its child nodes for the COST category.
SO THE RESULT SET SHOULD BRING LIKE THIS
WBS_NUMBER, PERIOD_NUMER, COST_CATEGORY , AMOUNT
ROOT
1
1.1
2
2.1
3
3.1
3.1.1
3.2
4
4.1
4.2

SQL help. Identify changes on a field.

Greetings!
PS/SQL is not an option for me. I need help to use SQL, if possible for the following scenario.
Oracle 10G.
Table : JOB_DATA
EMPLID, DATE_EFF, DEPTID, JOBCODE
100, 11/1/2012, 34567, MNG
100, 10/1/2012, 34567, SUP
100, 9/1/2012, 28967, MNG
100, 8/15/2012, 28967, SUP
100,6/30/2012,15879, MNG
I need to get the following records only, that is ,whenever changes in Department ID.
100, 10/1/2012, 34567, SUP
100, 8/15/2012, 28967, SUP
100,6/30/2012,15879, MNG
Thanks in advance.

Hi Rama,
Next time please post table structure and sample data.
Please read SQL and PL/SQL FAQ
Here another way to do it:
WITH job_data AS
   SELECT 100 emplid, TO_DATE('11/1/2012', 'MM/DD/YYYY') date_eff, 34567 deptid, 'MNG' jobcode FROM DUAL UNION ALL
   SELECT 100 emplid, TO_DATE('10/1/2012', 'MM/DD/YYYY') date_eff, 34567 deptid, 'SUP' jobcode FROM DUAL UNION ALL
   SELECT 100 emplid, TO_DATE('9/1/2012' , 'MM/DD/YYYY') date_eff, 28967 deptid, 'MNG' jobcode FROM DUAL UNION ALL
   SELECT 100 emplid, TO_DATE('8/15/2012', 'MM/DD/YYYY') date_eff, 28967 deptid, 'SUP' jobcode FROM DUAL UNION ALL
   SELECT 100 emplid, TO_DATE('6/30/2012', 'MM/DD/YYYY') date_eff, 15879 deptid, 'MNG' jobcode FROM DUAL
SELECT emplid, date_eff, deptid, jobcode
FROM (SELECT j.*
             , DENSE_RANK() OVER (PARTITION BY emplid, deptid ORDER BY date_eff) rn
         FROM job_data j
WHERE rn = 1
ORDER BY date_eff DESC;
    EMPLID DATE_EFF       DEPTID JOBCODE
       100 10/01/2012      34567 SUP
       100 08/15/2012      28967 SUP
       100 06/30/2012      15879 MNG   PARTITION BY emplid, deptid means that any time this combination of value is changing the rank will start again from 1.
The rank is ordered by date_eff.
I assume that you don't have the same date_eff for more than one record. If you have same date_eff for more than one record you need to explain what will be the logic in this case.
Regards.

SQL Help for System Analysis

Hi all,
Can we seek for help in SQL?
I have an system analysis which calculate the concurrent usage of a computer system.
I have add all data which is stored in .CSV file and then insert into a table named as Activity.
Can we select the data from activity and generate an Excel file which report the calculation on the concurrent usage of a computer system?

So, you have data in a .csv file
Then you load that data into a relational database.
Now you want to select that data and place it back into a file for Excel ......
Hmm.. Makes me wonder why you bothered with the database in the middle.
the database itself is more than capable of efficiently performing your calculations (assuming a reasonably rational table design).
Maybe you could provide a better description of the business problem to be solved, instead of a pre-conceived (and possibly ill-conceived) technical solution to that unspecified business problem. The we could provide better advice.

Oracle SQL/ PL-SQL help

Dear Experts,
If my below query returns any rows, I want this to trigger an alert, I'm writing a shell script to do this, need help how to implement the SQL part of it. I don't think IF EXISTS is directly supported in oracle, is there a PL/SQL alternative to check below query returns any rows and if so, I need to set an alert, with row data emailed out to group.
select a.col1 from table1 a
MINUS
select b.col1 from table2 b;Thanks

In a general case you should use the Stefanetti-Kyte method as suggested in {thread:id=2432829} where you could read:
If a row is duplicated in A , then MINUS will "de-dup" it silently
select *
from (select 1 from dual union all
        select 1 from dual union all
        select 1 from dual union all
        select 2 from dual union all
        select 3 from dual
       ) a
       minus
       (select 1 from dual union all
        select 2 from dual union all

Grouping Rules in PL/SQL Help needed

Hi I have a requirement where I wan to group based on the below scenario
I have a Table_A
Table_A strcuture:
create table table_a
code number,
name varchar2 (100),
city varchar2 (100),
dept varchar2 (100));;
insert into table_a
values
1,'ABC','EA','A');
insert into table_a
values
1,'ABC','EA1','A');
insert into table_a
values
2,'BCD','EA2','A');
insert into table_a
values
2,'ABC','EA3','A'');
insert into table_a
values
3,'KBC','EA,'A');
insert into table_a
values
3,'ABC','EA,'A');
wan to group the above table data based on name,city,dept
I wan the data as
1           ABC             EA1    A
             BCD            EA2     A
2           BCD            EA2     A

             BCD            EA      A
Kindly any help will be needful for me

This is more of a presentation layer problem I would not handle it in SQL. For example if the presentation layer is SQL Plus you can use BREAK command, like this.
SQL> select * from table_a;
      CODE NAME       CITY       DEPT
         1 ABC        EA         A
         1 ABC        EA1        A
         2 BCD        EA2        A
         2 ABC        EA3        A
         3 KBC        EA         A
         3 ABC        EA         A
6 rows selected.
SQL> break on code
SQL>
SQL> select * from table_a order by code;
      CODE NAME       CITY       DEPT
         1 ABC        EA         A
           ABC        EA1        A
         2 BCD        EA2        A
           ABC        EA3        A
         3 KBC        EA         A
           ABC        EA         A
6 rows selected.
But if you still wish to do it in SQL the right way is to use ROW_NUMBER like this.
SQL> clear breaks
breaks cleared
SQL>
SQL> select * from table_a;
      CODE NAME       CITY       DEPT

Oracle SQL HELP with convert GMT to EST and DST and Date offset

Hi, I have a query that does not seem to work trying to convert a date field that is in GMT to est and using extract(timezone_hour FROM TO_TIMESTAMP_TZ as an offsetr
HEre is my sql
dtl.start_dt_gmt + (extract(timezone_hour FROM TO_TIMESTAMP_TZ( dtl.start_dt_gmt,'DD-MON-YYYY HH24:MI:SS TZH:TZM'))/24 ) START_DT_Local
If the date (dtl.start_dt_gmt) is may 1 and gmt starts at 04:00 AM , the extract offset produces -4
However, if the date (dtl.start_dt_gmt) is Feb 1 which begins at 05:00 AM GMT, the date offset still gives 04. What am i doing wrong? Any help would be appreciated. Thanks.
Saul

If your data is not associated with timezone then you'll have to use something like
case when dt between A and B then dt-1/24 else dt end; <-- This will give you 1 hour back of EDT. So, as far as concern at database level, it is nothing to do at db level, because db is used by application, so you need to code in the app.
Oracle never actually changes a TIMEZONE column value when you set your system to be on daylight savings time. There are several built-in DST DATE conversion functions for changing to daylight savings time:
current_date
current_timestamp
localtimestamp
dbtimezone
sessiontimezone
extract
from_tz
to_timestamp
to_timestamp_tz
to_yminterval tz_offset

removed after desc in the last line so now this query will run and throw an error.

Clearly your error is because the string concatenation you are doing with sys_connect_by_path is exceeding the 4000 bytes permitted by SQL.
In that case you need to concatenate your data into a CLOB datatype, for which you'll need a CLOB aggregation function...
create or replace type clobagg_type as object
