Associative Array our only option?

Hello,
I'm having a problem accepting associative arrays as the only option I have for getting data from a stored procedure. I have a good reason for not wanting to use ref cursors as I am using the stored procedure to manipulate data which I in turn would like to pass back to VB through the stored procedure and would rather not have to insert he data into a table just to re-select it for a ref cursor.
My main concern is that with associative arrays I am expected to define the number of return results before I even generate the data. Also from what I can see I am required to set the data length for each and every item in said array one at a time. All this overhead seems like more work than what I would have to do to utilizer a reference cursor. Is there a right way to do this? I would really like to do the most straight forward way I can without the extra processing.

Hi,
Here's a blog post of mine that illustrates using pipelined functions and PL/SQL to return results:

Not sure if that will be helpful in your case, but perhaps it might be a place to start anyway.

Associative array related problem

Hi All,
When I am trying to use assotiative array in a select statement I recieve the following error:
ORA-06550: line 9, column 22:
PLS-00201: identifier 'COL1' must be declared
ORA-06550: line 9, column 22:

ORA-06550: line 9, column 10:
PL/SQL: ORA-00904: : invalid identifier
ORA-06550: line 9, column 3:

Here is the example
--create table MyTable (col1 varchar2(255), col2 varchar2(255))
declare
type m_ttMyTable
    is table of MyTable%rowtype index by MyTable.col1%type;
m_tMyTable                   m_ttMyTable;
m_sCol2 varchar2(255);
begin
select m_tMyTable (col1).col2 /* works with ocntant: select m_tMyTable */('col1').col2
    into m_sCol2
from MyTable
where rownum = 1;
end;
--drop table MyTableAny ideas how to workaround this?
Thanks

The only collection types SQL can query are ones defined in SQL using CREATE TYPE. That excludes associative arrays, as they are PL/SQL-only constructs. I'd recommend a nested table collection.

Associative Array error

I am using a couple associative arrays in my code and comparing the data in one, and if it is an asterisk, I change it to use the data in the other. Here is the meat of my code. I am running into an error at the bolded line saying I have too many values, which I don't understand because the code is the exact same as the block of code right before it where I populate the first array. FYI, the table it is pulling from only has one row. The error is listed below the code.
Code
DECLARE
TYPE refresh_file_t IS TABLE OF test.loading_dock%ROWTYPE ;
refresh_data refresh_file_t ;
prospect_data refresh_file_t ;
TYPE CV_TYPE IS REF CURSOR ;
c_id CV_TYPE ;
v_id NUMBER(10) ;
v_phone VARCHAR2(10) ;
v_project VARCHAR2(10) ;
BEGIN
OPEN c_id FOR
'SELECT id
FROM test.loading_dock
WHERE rownum = 1' ;
LOOP
FETCH c_id INTO v_id ;
EXIT WHEN c_id%NOTFOUND ;
SELECT * BULK COLLECT
INTO refresh_data
FROM test.loading_dock
WHERE id = v_id ;
SELECT * BULK COLLECT
INTO prospect_data
FROM test.prospects
WHERE id_number = v_id ;
IF refresh_data(1).home_phone = '*' THEN
v_phone := prospect_data(1).phone ;
ELSE
v_phone := refresh_data(1).home_phone ;
END IF ;
DBMS_OUTPUT.PUT_LINE(v_phone) ;
END LOOP ;
CLOSE c_id ;
END ;
Error
ORA-06550: line 29, column 13:

Collection prospect_data is of type refresh_file_t, which is a table of records of test.loading_dock%TYPE. Most likely tables test.loading_dock and test.prospects have different structure - test.prospects has fewer columns. So when you try to fetch from test.prospects into prospect_data you get the error Try replacing
prospect_data refresh_file_t ;with
TYPE prospect_data_t IS TABLE OF test.prospects%ROWTYPE ;
prospect_data prospect_data_t ;SY.

Associative Array (Object) problems

Here is the function i'm dealing with
i'm reading in a delimited string and using indexed arrays to
break them up and assign the keys and values to an associative
array in a loop.
i'm using variables in the loop and the array loads as
expected in the loop
but outside the loop, the only key is the variable name and
the value is undefined
this is true using dot or array notation, as well as literal
strings for the keys
any help is appreciated
watchSuspendData = function (id, oldval, newval):String {
//the incoming suspendData string is delimited by the
semicolon;
//newval is: firstValue=Yes;captivateKey=1
var listSuspendData:Array = newval.split(";"); // convert it
to a list of key/value pairs
if (listSuspendData.length > 0){
//line 123: listSuspendData.length is: 2
for (i=0; i < listSuspendData.length; i++){ //for each
key/value pair
var keyValArray:Array = new Array();
var myNameValue:String = listSuspendData
//line 127: listSuspendData is: firstValue=Yes
keyValArray = myNameValue.split("="); // split 'em on the
equal sign
var myKey:String = keyValArray[0];
var myVal:String = keyValArray[1];
//keyValArray[0] is: firstValue
//keyValArray[1] is: Yes
// store the key and the value in associative array
suspendDataArray.myKey = myVal;
trace("line 134: suspendDataArray is: " +
suspendDataArray.myKey);
// trace is line 134: suspendDataArray is: Yes on the first
pass and 1 on the second
//the below loop always returns one array key: myKey and the
value as undefined
for(x in suspendDataArray){
trace("x is: " + x); //x is: myKey
trace("the val is: " + suspendDataArray.x); //the val is:
undefined
} //end for
return newval;

on lines 12-13 i assign the key=value pair to string
variables
then on lines 17-18 i assign those values to the associative
array using dot notation
the trace seems to work there
the problem is that when the procedure exits the for loop,
the associative array only has one key (myKey) and no value
(undefined)
all the documentation i've read shows using these types of
arrays with either non-quoted property names like:
myAssocArray.myKey = "somevalue";
or
myAssocArray[myKey] = "somevalue";
i tried assigning the key/value pairs directly from the
indexed arrays, but the result was always undefined
like this:
suspendDataArray.keyValArray[0] = keyValArray[1]
or
suspendDataArray[keyValArray[0]] = keyValArray[1]
i even tried building a string in the loop and trying to
assign all the pairs at once using the curly brace
this is pretty wierd behavior for actionscript or i'm missing
something basic here
thanks for looking

Associative Array vs Table Scan

Still new to PL/SQL, but very keen to learn. I wondered if somebody could advise me whether I should use a collection (such as an associative array) instead of repeating a table scan within a loop for the example below. I need to read from an input table of experiment data and if the EXPERIMENT_ID does not already exist in my EXPERIMENTS table, then add it. Here is the code I have so far. My instinct is that it my code is inefficient. Would it be more efficient to scan the EXPERIMENTS table only once and store the list of IDs in a collection, then scan the collection within the loop?
-- Create any new Experiment IDs if needed
open CurExperiments;
loop
-- Fetch the explicit cursor
fetch CurExperiments
into vExpId, dExpDate;
exit when CurExperiments%notfound;
-- Check to see if already exists
select count(id)
into iCheckExpExists
from experiments
where id = vExpId;
if iCheckExpExists = 0 then
-- Experiment ID is not already in table so add a row
insert into experiments
(id, experiment_date)
values(vExpId, dExpDate);
end if;
end loop;

Except that rownum is assigned after the result set
is computed, so the whole table will have to be
scanned.really?

Distinct clause requires a sort. Sorts can be very expensive.
Bulk collects that are not constrained in fetch size, can potentially fetch millions of rows - requiring that data to be wholly read into server memory. I have seen how this can degrade performance so badly that the kernel reboots the server.
Using PL/SQL loops to process and insert/update/delete data is often problematic due to its row-by-row approach - also called slow-by-slow approach. It is far more scalable letting SQL do the "loop" processing, by using joins, sub-selects and so on.
Where the conditional processing is too complex for SQL to handle, then PL/SQL is obviously an alternative to use. Ideally one should process data sets as oppose to rows in PL//SQL. Reduce context switching by using bulk fetches and bulk binds.
But PL/SQL cannot execute in parallel as the SQL it fires off can. If after all the optimisation, the PL/SQL process still needs to hit a million rows to process, it will be slow irrespective of how optimal that PL/SQL approach and design - simply because of the number of rows and the processing overheads per row.
In that case, the PL/SQL code itself need to be parallelised. There are a number of ways to approach this problem - the typical one is to create unique and distinct ranges of rows to process, spawn multiple P/SQL processes, and provide each with a unique range of rows to process. In parallel.
So you need to look close at what you are trying to achieve, what the workloads are, and how to effectively decrease the workloads and increase the processing time of a workload.
For example - finding distinct column values. You can pay for that workload when wanting that distinct list. And each time afterward repeat that workload when wanting that distinct list. Or you can pay for that workload up-front with the DML that creates/updates those values - and use (for example) a materialised view to maintain a ready to use distinct list of values.
Same workload in essence - but paying once for it and up-front as oppose to each time you execute your code that needs to dynamically build that distinct list.
Kent Crotty did tests and showed stunning performance improvements with bulk collect and forall, up to 30x faster:Bulk processing is not a magical silver bullet. It is a tool. And when correctly use, the tool does exactly what it was designed to do.
The problem is using a hammer to drive in screws - instead of a screwdriver. There's nothing "stunning" about using a screwdriver. It is all about using the correct tool.
If the goal of the swap daemon is to free up "idle" chunks of memory, and try to use that memory for things like file cache instead, what does that have to do with bulk processing?The swap daemon reads virtual memory pages from swap space into memory, and writes virtual pages from memory to swap space.
What does it have to do with bulk processing? A bulk fetch reads data from the SGA (buffer cache) into the PGA (private process memory space). The larget the fetch, the more memory is required. If for example 50% of server memory is required for a bulk collection that is 2GB in size, then that will force in-use pages from memory to swap space.. only to be swapped back again as it is needed, thereby forcing other in-use pages to swap. The swap daemon will consume almost all the CPU time swapping hot pages continually in and out of memory.

Associative array Basics

I have a SELECT query like
SELECT ename, sal from emp;
I want the ename column values from the output of the above query to be populated into an Associative array. So i did the following steps
DECLARE
TYPE ename_type IS TABLE OF VARCHAR2(10) INDEX BY PLS_INTEGER;
v_ename ename_type;
What is the next step by which i could populate the v_ename variable with the ename column values from the above query?

One slight problem.
The ename is derived from a large SELECT query joining three tables. The SELECT query looks like
SELECT ename,max(sal) from ...............;
I only need ename values from this SELECT query to be populated to the Assosiative array (v_ename). But I cannot exclude max(sal) from the query due to aggregate function's technical reasons(GROUP BY and so on).
So when i try to populate the associative array v_ename by issuing the following command:
SELECT ename BULK COLLECT INTO v_ename FROM (SELECT ename,max(sal) from ...............) ;
The max(sal) value in the SELECT query is going to be a problem. How do i solve this?

Associative Array to Nested Table: Anything faster?

(First Post! Some ASP.NET references, but I think this really is a PL/SQL question)
I work on a team that runs an Oracle instance for data warehousing and reporting along with an ASP.NET based website for display.
Sometimes, I may want to have many parameters come in and only show records that match those parameters. For example, I may want to show all employees who are Managers or Developers and not show employees who are Accountants or Scientists. Typically, I send a parameter into my PL/SQL stored procedures as an associative array (as declared in my package specification). Once in the procedure, I convert that associative array into another associative array (as a user created SQL type) and then I'm able to use it like a nested table to join on.
My question is: in your experience, is there any way to get around this type conversion or another faster way?
For example:
-- Create the sql type
CREATE OR REPLACE TYPE DIM.sql_string_table AS TABLE OF VARCHAR2(255);
--pretend that this works and it's in a package body
declare
type string_table is table of varchar2(255) index by binary_integer;
l_job_types string_table; -- Keep in mind I'd normally be sending this via ASP.NET
l_job_types_nested sql_string_table := sql_string_table();
begin
-- Add some data
l_job_types(0) := 'Manager';
l_job_types(1) := 'Developer';
-- Do the conversion
for i in l_job_types.first .. l_job_types.last
loop
l_job_types_nested.extend;
l_job_types_nested(l_job_types_nested.count) := l_job_types(i);
end loop;
-- get some data out (we're pretending)
open fake_ref_cursor for
Select e.*
from employees e,
the(select cast(l_job_types_nested as sql_string_table) from dual) jobs_types_wanted
where e.type = value(jobs_types_wanted);
end;
The result would be all employees whose have a type that was input into the l_job_types associatve array.
See: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:110612348061
for additional reference

> I convert that associative array into another associative array (as a user created SQL type)
Just so we're clear, Oracle use the term 'associative array' to refer to the exclusively PL/SQL sparse collection type ("table of x index by pls_integer" etc) as distinct from the common nested table collection type.
Also I could be wrong but I think
SELECT ..
FROM the(select cast(l_job_types_nested as sql_string_table) from dual) jobs_types_wantedis generally the same as
SELECT ..
FROM TABLE(l_job_types_nested) jobs_types_wantedthough "SELECT *" and implicitly collection casting don't always mix. The "THE()" syntax is deprecated.

Associative Array, Drp-DwnList and Accesing "SubArray" Values ?

Based on the users selection on a drop-down box, I need to be able to access different elements associated with that selection (elements of a subArray, so to speak)
I am not certain how to go about creating arrays in LiveCycle. I've tried a number of things including:
putting the array name in the "variables tab" of the Form Properties, with a value of [] -- that doesn't seen to be the way to go, so I removed it
using rounded brackets ( instead of square [
declaring the arrays differently using var codeDetail = new Array(array,Values,Here);
putting the code in a fragment--not sure how to reference the values,
I have the following code residing in the "Exit" event for the drop-down box:
var codeDetail = [];   //an associative array
codeDetail["99999"] = ["None",null,null,null,null,null,null,null];
codeDetail["78400"] = ["Trampoline",40,45,50,60,10,20,40];
codeDetail["78020"] = ["Horse(s)",10,12,15,20,5,10, 20];
codeDetail["78401"] = ["Horse Boarding (each)",19,23,28,39,17,24,48];
codeDetail["78010"] = ["Watercraft - Outboard over 50 HP (each)",13,18,20,24,17,24,48];
codeDetail["78011"] = ["Watercraft - Inboard or I/O over 50 HP (each)",30,35,40,50,17,24,48];
codeDetail["78050"] = ["Recreational Vehicle: ATV (each)",40,51,61,84,9,11,22];
codeDetail["78053"] = ["Recreational Vehicle: Snowmobiles (each)",36,46,55,76,9,11,22];
codeDetail["78052"] = ["Recreational Vehicle: Golf Carts (each)",29,37,44,61,9,11,22];
codeDetail["73000"] = ["Personal Injury",14,19,22,31,null,null,null];
codeDetail["78030"] = ["Office, School or Studio",10,11,13,19,9,17,34];
codeDetail["78060"] = ["Retail Sales",36,46,56,77,3,4,8];
codeDetail["78061"] = ["Incidental Business Pursuits",36,46,56,77,3,4,8];
codeDetail["78070"] = ["Additional Insured: Premises Only",8,10,12,17,null,null,null];
codeDetail["78090"] = ["Additional Insured - Personal Libility",31,40,50,69,9,17,34];
codeDetail["78040"] = ["Seasonal Residence Occupied by Insured",10,11,13,19,3,4,8];
codeDetail["78041"] = ["Rented to Others: One Family",23,28,34,47,9,17,34];
codeDetail["78042"] = ["Rented to Others: Two Family",29,35,43,61,11,23,45];
codeDetail["78043"] = ["Rented to Others: Three Family",43,55,66,90,17,33,60];
codeDetail["78044"] = ["Rented to Others: Four Family",67,83,100,139,24,50,80];
codeDetail["76000"] = ["Waterbed Liability",10,12,13,19,null,null,null];
codeDetail["78300"] = ["Non-Owned and Hired Auto Liability",56,69,80,92,17,24,48];
itemChosen = []; //a subArray
var i = this.rawValue
itemChosen = [codeDetail[i]];    // values based on user's selection
The goal is to now be able to use the itemChosen values and simply refer to them:
this.rawValue = itemChosen[i]   or   this.rawValue = itemChosen[someField.rawValue]
So if this drop-down box has a rawValue = "78400" then itemChosen[2] would have a value of 45 (see above).
Am I anywhere close?
Also, a couple of other questions:
When using a variable.value or a field.rawValue as the index value for itemChosen[i]
do you include "" or .value or .rawValue in the index brackets?
Do you ever use .value when referencing an array as in: itemChosen[i].value
How do I make sure arrays and variables created like this are global, or not? I tried with and without the "var" declaration
Thanks much!
Stephen

I've just been playing with a similar thing.
My code is based on a sample from WindJack Solutions, which is available here:

Check this thread for a good sample from Bruce, he took my code and jacked it up considerably.

Associative array two variable comparison :update table error

Hi,
i am using associative array to update the version number of table
-i declare two associative array to compare the column from two table (temp,main tables)values in loop
-if id's of both variable(for temp and main table) are equal and column of either of table not matching then it should update the version no of temp table
-if id's not equal i.e record only exists temp table then update null version number annd increment it by 1
-following is the structure and procedure --it shows the matching and non matching records but for the update statement it not giving expected output i.e it updates all records irrespective of the condition provided
-i tried to put condition in update as well as in the if statement but it updates all record
....suggestion and help highly appreciate. thankx in advance !!!

Hello user8937641
I think there is a problem with the logic of your SQL-Code.
But maybe in this formatted structure you can see where your problem is. -> I can not say it because I do not know what is the requirement.
I hope it helps...

Without loops how can i read data from associative Array??

Hi all,
I am facing scenario like...
i need to read data from associative array without using loops is it possible,
CREATE OR REPLACE PACKAGE BODY test_pkg IS
    TYPE t1 IS TABLE OF NUMBER INDEX BY BINARY_INTEGER;
   -- in array we can expect more than one row or sometimes no data also.
FUNCTION test1(vt1 T1 DEFAULT CAST(NULL AS t1)) RETURN NUMBER IS
BEGIN
    -- basically in array we'll get data of column2
    -- this loop should satisfies table1.colum2 = nvl(NULL, table2.colum2 )if array is null.
    -- if array is not null then only compare with array values
    FOR i IN (SELECT t1.colum1,t1.column2
                     FROM table1 t1, table1 t2
                          WHERE t1.colum1 = t2.column1
                            AND t1.colum2 = nvl(vt1, t2.colum2)
      LOOP
        generateTEXT(i.colum1, i.colum2);
     END LOOP;
END test1;
END test_pkg;
in table1 we have date like...
colum1          column2
Jan                  1
Feb                  2
Mar                  3
if i call select test_pkg.test1(1) from dual then output should
be Jan..
and
select test_pkg.test1(null) from dual then it should display all elements from table1.
Jan                  1
Feb                  2
Mar                  3,
Thanks for your quick replay..

i need to read data from associative array without using loops is it possible,
No - you would need to create a SQL type and then use the TABLE operator to unnest the collection.
create or replace TYPE my_nums IS TABLE OF INTEGER;
DECLARE
-- TYPE my_nums IS TABLE OF PLS_INTEGER INDEX BY PLS_INTEGER;
v_nums my_nums := my_nums(1, 2, 3);
v_total number;
BEGIN
select sum(column_value) into v_total from table(v_nums);
DBMS_OUTPUT.PUT_LINE
    ('Sum of the numbers is ' || TO_CHAR(v_total));
END;
Sum of the numbers is 6

How to share an associative array throughout the entire instance?

Hi all,
I have an associative array with much data, and it would barely change, I want to keep it in the memory and share it throughout the entire instance, and make sure all sessions of all users get the same associative array, is it possible?
Thanks in advanced.

>

Why do you want to keep it in memory?
Will using a table for that, which being accessed frequently, will practically always be in the buffer cache, cause performance problems for you?
The only other way to keep data in memory globally accesable to all database sessions is to use the global application context feature. With that you can store [name;value] pairs in memory and easily access (read) them using the SYS_CONTEXT built-in.

Create an association in the folder options control panel.. pop up dialogue

Installed on a win XP OS:
Oracle Database 10g Release 2 (10.2.0.1)
Oracle Database 10g Express Edition (Universal)
Oracle Database 10g Express Edition (Western European)
I keep getting this pop up dialogue box whenever I click go to Database Homepage.
"This program does not have a file attached with it to perform this action. Create an association in the folder options control panel."
I'm planning to learn Oracle and SQL*Plus so I'm not sure what version I need for basic usage. I only need the SQL command line and probably an application that can create database or tables easily.
Any suggestion will be appreciated. Thank you.

Thank you for replying Hans,
I tried to type http://localhost:8080/apex into my browser, the result is:
Unable to connect
Firefox can't establish a connection to the server at localhost:8080.
* The site could be temporarily unavailable or too busy. Try again in a few

* If you are unable to load any pages, check your computer's network

* If your computer or network is protected by a firewall or proxy, make sure

The SQL command line is working, but just going to the Database Home Page would result to that pop up dialogue box. Any idea why this is happening? Thanks.

What if my ipod touch 4th generation can't update and now the only option is to restore it. And i don't know what happens if i press restore?

What if my ipod touch 4th generation can't update and now the only option is to restore it.
And i don't know what happens if i press restore?
Will it show my back up and back it up or what?
And if that does happen will all my pictures stil be there?
Also i'm not on a apple computer.

To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
Either a PC or Mac work the same.
The photos in our iPod's Camera Roll album will be restored as will the last 30 days of photos in our PhotoStream album
