Dynamic INSERT from associative array

Ok, this would be an one-liner in python or perl, but as a newbie in PL/SQL, it feels like swimming in molasses. So before going on and reinvent the wheel, is there any builtin or sample code that generates dynamically an insert statement from a hashtable ? That is, given a table:
hashtable = {
'name' : 'Michael',
'age' : 23,
'income' : 67213.34
and a table_name ('Employee'), generate the query
INSERT INTO Employee (name,age,income) VALUES ('Michael', 23, 67213.34);
Thanks,
George

Well, we have been in product development for past dozen years. In my humble opinion, we know a thing are two about product design. But thanks for your inputs though.
Obviously you are not doing so well with this "design"... Just sayin'... :) :)
You seems to be expert in the application/product design. Have you ever heard of "user data mashup" concept in data warehousing? Just curious.
"user mashup" would indicate that the user actually controls how this is done. You, as a "product" will be making some [potentially very bad] assumptions about the end-user data that cannot be accounted for in a "canned" product. You can influence how it is done, but, in the end, does it meet the exact business needs of the end-user.
you could possibly use some PL/SQL packages to
1) get all of the tables
2) get all of the columns.
3) do the mashup.
Now a question. Let's say table1 and table3 have (col1 + col2) that are the same and column3 is different. What do you put in column3?? or is this another row.

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

Inserting a associative array into a table

Hi,
I am working on a process where I want to store the temporary results in an associative array. At the end of the process I plan to write the contents of the array into a table that has the same structure. (the array is defined as a %rowtype of the table)
Is it possible to execute ONE sql statement that transfers the array into the table? I am on 10g (10.2.0.4.0)
Here's what I have now:
declare
type t_emp is table of emp%rowtype index by pls_integer;
v_emp t_emp;
begin
-- a process that fills v_emp with lots of data
for i in v_emp.first .. v_emp.last
loop
    insert into emp values v_emp(i);
end loop;
end;But it would be better if the loop could be replaced by sql one statement that inserts all of v_emp into emp. Is that possible?
Thanks!
PS: I'm not sure whether it's a good idea to use this approach... building a table in memory and inserting it into the database at the end of the process. Maybe it's better to insert every record directly into the table... but in any case I'm curious to see if it is possible in theory :)
Edited: Added version info

True, SQL cannot access the PL/SQL type.
So you can not do something like this:
insert into emp
select * from table(v_emp)That is not possible.
But FORALL is possible:
FORALL i in v_emp.first .. v_emp.last
    insert into emp values v_emp(i);FORALL makes just one "round trip" to SQL bulk binding the entire contents of the array.
It is much more efficient than the normal FOR loop, though it is mostly a PL/SQL optimization - even the FORALL actually inserts the rows "one at the time", it just hands the entire array to the SQL engine in one go.
If the logic has to be done procedurally, FORALL is efficient.
If the logic can be changed so arrays can be avoided completely and everything done in a single "insert into ... select ..." statement, that is the most efficient.

Dynamic insertion of elements based on dynamic condition

I need to achieve the following:
Input:
<Customer>
     <name>Name1</name>
     <email>Email1</email>
     <phone>Phone1</phone>
     <Number>Num1</Number>
<Customer>
Output:
<Customer>
     <name>Name1</name>
     <email>Email1</email>
     <phone>Phone1</phone>
     <Number>Num1</Number>
     <Addresses>
          <Address>add1</Address>
          <Address>add1</Address>
          <Address>add1</Address>
     </Addresses>
<Customer>
Based on the number of Addresses that exist for the customer, multiple <Address> elements should be added.
I can't determine number of Addresses at the beginning. It is deterrmined dynamically based on certain condition.
So each time when the condition is met, I need to get the count of <Address> elements that exist and insert the new one last.
My logic:
     Switch (case)     ==> Add <Address> only if condition is met
          count ==> count(bpws:getVariableData('outputVariable','payload','/ns1:Customer/ns1:Addresses')) ==> 0 first time
          <Addresses>
               <Address>add1</Address> ===> Now I need to insert this.
          </Addresses>
I have the following in my bpel:
<assign name="AssignInsertAfterExisting">
<copy>
<from expression="count(bpws:getVariableData('outputVariable','payload','/ns1:Customer/ns1:Addresses'))"/>
<to variable="NumberOfAds"/>
</copy>
<copy>
<from expression="'123 street'"/>
<to variable="nextAddress"/>
</copy>
<bpelx:insertAfter>
<bpelx:from variable="nextAddress"/>
<bpelx:to variable="outputVariable" part="payload"
query="/ns1:Customer/ns1:Addresses/ns1:Address squareBrakets NumberOfAds squareBrakets"/>
</bpelx:insertAfter>
</assign>
But with the above I am receiving the folllowing error:
     Assign Operation Misuse.
     The to-spec does not yield any data; insertAfter operation cannot be performed.
Please check the BPEL source at line number ..
I can I insert dynamically insert elements into array. I have seen the example provided in samples, but my problem is little different than that.
Edited by: user10367892 on Aug 4, 2009 3:16 AM

append is appending value of variable to existing element, instead of creating a new element in the array:
For Eg:
Input:
<bpelx:append>
<bpelx:from variable="nextAddress"/>
<bpelx:to variable="outputVariable" part="payload" query="/ns1:Customer/ns1:Addresses/ns1:Address"/>
</bpelx:append>
Output if nextAddress = Address2 and if <Address>Address1</Address> already exists
<Customer>
     <Addresses>
          <Address>Address1Address2</Address>
     </Addresses>
</Customer>

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.

Excel & ActiveX: Insert arbitrary columns from 2D array and create graph problems

Hi there,
I want to insert data from either a 1D or 2D array from LabView into Excel and create graphs.
I used the information from the following example:
http://www.ni.com/example/28934/en/
and was able to create a new Excel file (I'm using Excel 2010), writing data from an 1D array to a column in excel by creating a while loop and using the first element of the array to write it to a specific cell. I use the counter of the loop to write to the next cell when the loop starts over and always delete the first value, which I write to the cell, from the array until it is empty.
Now I also would like to write a 2D array - so the first column in Excel should be the first column from the array and so. Here I cannot use the loop counter directly as Excel only counts 1,2,... for the rows, but uses A,B,... to count columns. Also I do not know in advance how many columns my 2D array will contain, so creating a lookup table like (A means 1, B means 2,...) is not really an option (except there really is no other way). Is there a possibilty to convert numbers into letters or some way to 'explain' to the program that column 2 in the array means column B in Excel for example, or is there a way to insert new columns?
I figured out how to add new Worksheets and as I also need to create a certain number of Worksheets and I know that on standard 3 sheets are present when creating the file, I use the 'add' methode to create every new worksheets before worksheet 3 - I could use the same methode to create new columns in Excel, but so far I didn't find a methode to do so. Or is there a way to enter the whole 2D array at once?
Then I'd like to create a graph (in case of the 1D arrays a bar plot, when using 2D arrays a 3D plot) to view the data. I found this example:
http://www.ni.com/newsletter/51339/en/
-> as I do not have the toolkit I'd like to do it using ActiveX directly, so I tried to do things like shown under the headline 'DIY ActiveX/.NET'
I tried to load the snippet to a new Excel file but got the error message 'microsoft.office.interop.excel.dll not found' and hence the code is not working. That confuses me a little as I would guess when this dll is not present I cannot access Excel from LabView at all, though my understanding of what I'm really doing so far is quiet limited. ;-)
Also - as far as I understand from the snippet - when creating a new chart object I should be able the create methodes for it, however when I do a right click on the chart object of an ActiveX Worksheet symbol there are none listed.
To explain my problems better I added a snippet showing my two problems: The inner of the two while loops shows how I import a 1D array. In the outer loop I seperate the columns. I know that currently this is not working as all data end up in column A of the Excel sheet - so I would need to convert the number of the outer counter to A, B,... or find a different solution.
Moreover on the snippet I placed an ActiveX Worksheet Property with the Chart Object - as I can see the difference to the Chart Object in the example code from the last link above is the color. However I'm not sure what that means and how to change/ solve this.
And just to make sure - I know this way the VI does not run as the Chart Object is placed completely wrong - I just did it, so it is included in the snippet.
I'd be thankful for any suggestions,
Thanks!
Solved!

Hello everyone and thanks for the answers.
I only have the LabView Student Edition available here - is the toolkit included in it too. How can I check if it is installed/ available and in case it is installed - where can I find it?
Today I had time to take a look at the example
Create via ActiveX Labview a XY Scatter plot graph on an excel sheet
It almost does what I want in terms of creating a graph. The only problem I could not fix, is that in this example a sheet is created where only the graph is present. i'd like to add the graph to a previously created worksheet. Today I tried get this working but it seems I stilll don't really understand what I'm doing, I'll post a snippet of my code as soon as I can access the PC with LabView on it again.
I also took a look at the other example for inserting 2D attays - it seems to be what I need, I just had no time so far to test it, I'll post an update when I could test it.
Thanks for the help so far!

I want to insert 2d array (XY position)to XY graph and can delete the data from the array too.

Firstly, I receive the data of X and Y position one by one seperately and then I add this two value (numeric double) to array two column (XY). After I press ok button the new data for X and Y will come and be added to the last row of my data. Then I use this data to plot in XY graph. All of this I did it already, but I want more additional function.
My additional function is I want to add or delete a pair of data XY from the array at the row that I defined. This one I can not do it.....

You use the Insert Into Array and Delete From Array functions on the Array palette. Here's a simple example in 6.0 that shows how they're used.

How do u create a datatable from PLSQL Associative Arrays returned from SP

Using C# 4.0 ODP.NET 11g, vs2010 on Windows XP.
Have a procedure that takes two input values and returns 35 PL\SQL Associative Arrays (pl/sql tables). I am currently able to call the proc and have it returned the values. i end up with 35 arrays each 35 elements in length.
I want to create a datatable from them but am at a lost on how to do so.
This what i have
Oracle.DataAccess.Client.OracleCommand oCommand = new Oracle.DataAccess.Client.OracleCommand();
oCommand.CommandText = ProcName;
oCommand.CommandType = CommandType.StoredProcedure;
//Input Parameters
OracleParameter param1 = oCommand.Parameters.Add("p_orderid",OracleDbType.Int32);
param1.Direction = ParameterDirection.Input;
param1.Value = OrderID;
OracleParameter param2 = oCommand.Parameters.Add("p_testinstanceid", OracleDbType.Int32);
param2.Direction = ParameterDirection.Input;
param2.Value = TestInstanceID;
//Output Parameters
OracleParameter param3 = oCommand.Parameters.Add("program_id", OracleDbType.Int32);
param3.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
param3.Direction = ParameterDirection.Output;
param3.Size = 50;
OracleParameter param4 = oCommand.Parameters.Add("normyear", OracleDbType.Varchar2);
param4.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
param4.Direction = ParameterDirection.Output;
param4.Size = 50;
param4.ArrayBindSize = new int[50];
// set the bind size value for each element
for (int i = 0; i < 50; i++)
param4.ArrayBindSize[i] = 10;
...33 more output parameters all PLSQLAssociativeArray type
oCommand.ExecuteNonQuery();
OracleDataAdapter da = new OracleDataAdapter(oCommand);
//Fill the DataTable
da.Fill(dt);
The datatable is empty. What am i doing wrong? Or this there a better way to get the output values to end up in a datatable. Note that when i examine the parameters in oCommand i see that they all the the right out values.

I have multiple where conditions which needs the same subqueryThat is where the Subquery Factoring Clause comes in handy, because then
»Oracle Database optimizes the query by treating the query name as either an inline view or as a temporary table«
with temp as (
subquery
select 1
from table1
where col1 in (select * from temp)
and col2 in (select * from temp)
and col3 in (select * from temp)

How to auto insert a number array with size of 20 into a named excel file with the positon is from A1 TO A20?i use lv6.1

can you give me a example vi for it ?thanks a lot!
how to auto insert a number array with size of 20 into a named excel file with the positon is from A1 TO A20?i use lv6.1

You don't need us to give you an example, as the example already comes with LV. Go to Help>>Find Examples and search for "excel". You will find an example called "write table to XL". You should note that the example doesn't do that exactly, because it writes a 2D array from 2 to N.
You can modify the example by using only one for loop (instead of nested loops) with a 1D array or by going into the Set Cell Value and modifying it to accept a second cell value for the Cell2 terminal and wiring in a 1D array instead of the single string. If you do modify it, be sure to save it under a different name, so you don't overwrite the original.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).

Is it possible to enable DOM events from a dynamically inserted QuickTime?

QuickTime in IE uses an <object> as a 'behaviour' template in order to enable DOM events. The behaviour <object> is referenced from the QuickTime plugin instance with IE's behavior style: style="behavior: url(#idof_behaviorobject)".
This works great for all QuickTime <object> instances declared before window.onload, but QuickTime <object> instances inserted into the DOM after that do not pick up the DOM events behaviour.
I do not know exactly how behaviour styles work and what I've read so far hasn't made me any the wiser. Are behaviours called on elements that reference them, only on page load, and therefore can't be picked up later?
Are there any known workarounds for enabling DOM events from QuickTime objects inserted after page load?
Just so you know - I've tried various methods of DOM insertion - innerHTML, createElement, and calling iframes with their own html page containing the necessary objects. None of these work for enabling DOM events on insertion after page load.
( P.S. I've cross-posted this question on stackoverflow here:
http://stackoverflow.com/questions/1336678/is-it-possible-to-enable-dom-events-f rom-a-dynamically-inserted-quicktime-object
If I get a working answer I'll copy it across. )
Cheers!
Stephen.

I found forwarding the impl_processMouseEvent kind of works ... except when the graphics of the transparent child window floats over the owner window's chrome elements - in particular the title bar, minimise/maximise and resized borders won't accept forwarded mouse events this way.
Not true mouse transparency.

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 Question

Hi All,
I've searched through this forum trying to find information I'm needing on associative arrays with a varchar2 index without luck. What I'm looking for is a way to get the index or "key" values of the array without knowing what they are. Meaning, I wouldn't have to know the index value when designing the array but would be able to utilize them values at runtime. For those familiar with Java it would be like calling the keySet() method from a Map object.
So, if I have an array of TYPE COLUMN_ARRAY IS TABLE OF VARCHAR2(4000) INDEX BY VARCHAR2(100) is there any way to dynamically get the index values without knowing what they are?
Any help is appreciated.
Thanks

Thanks for the response.
I am aware of using FIRST and NEXT for iterating the array but can I extract the index value of the current element into a variable when I don't know what the index value is at runtime ?
Thanks
