Better way for inserting column into array?

I have to insert a 2-D array(20x10) into the end (column) of a bigger 2-D array(1000x10). I am seeing two ways to do that:
1. Insert smaller 2D array at the end of bigger array.
2. Insert the bigger array at the 0th column of smaller array.
Which one would be more efficient? Will there be any performance difference?
Or any other better way to do this?
The second one looks simpler but I think it would require a bigger copying of memory.

Both methods use a buffer allocation, so they might be very similar. Since we don't know what the compiler is doing, you could also try this:
I am assumung that you only need to append once and not append more and more columns as the program progresses. Is this correct? In any case, you should consider operating on the transposed version, because it is always easier to append rows instead of columns (rows are adjacent in memory, while appending columns require more data shuffling under the hood
In any case, you should simply wire up the alternatives and do a proper benchmark if you are planning to use this on much larger arrays in the future, for example. Can you give us some context how you are planning to use this?

Is there a way to Insert Data into a Lookup Column Type on a SharePoint List Destination in SSIS?

Greetings.
I have successfully worked out inserting SQL data (2008 R2) into my 2010 SharePoint list (New, Update, Delete) by creating an SSIS Data Flow Task as outlined here:
http://fsugeiger.blogspot.com/2010/01/synchronise-sql-table-with-sharepoint.html
However, the problem I am running into is inserting data into the SharePoint Columns that are "Lookup" column types. I verified that all of the values I am copying from SQL into the SharePoint lookup column exist in the customn list it is pointing to. It
is important to have this column be a lookup column as it links to another custom list that has many more columns of related information.
I have read and re-read the SharePoint SSIS Adapters 2011.docx from
http://sqlsrvintegrationsrv.codeplex.com/ and the only section that seems to apply is this:
"Looking Up Values in a SharePoint List
If you have to look up a value in a SharePoint list, you can use the Lookup transformation in your data flow, and use the SharePoint List source to load the lookup table. You may have to add a Derived Column transformation or a Script component that splits
data in the lookup column on the ";#" delimiter to separate the ID value from the description.
If you are replacing values in your data with the values that you look up in the list, then loading the changed data back into SharePoint, you only have to include the ID from the lookup column. SharePoint ignores the description if you include it."
I am not sure if the above statement means that I should be passing the assocaited ID's other than the actual data into the SharePoint List destination. If that is the case, that will not really work as the lookup contains hundreds of rows. Not too mention
I have several of these lookup column types pointing to several different lists.
Any guidance in how I can put data into a SharePoint Lookup column type via Data Flow Task would be so much appreaciated.
Thank you.
My errors are:
Error: 0x0 at Data Flow Task, SharePoint List Destination: Error on row ID="1": 0x1 - Unspecified error, such as too many items being updated at once (batch), or an invalid core field value.
Error: 0xC0047062 at Data Flow Task, SharePoint List Destination [1903]: Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.PipelineProcessException: Errors detected in this component - see SSIS Errors at Microsoft.Samples.SqlServer.SSIS.SharePointListAdapters.SharePointListDestination.ProcessInput(Int32

component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will

I have found a solution to my problem and thought I would share it here in case there are others who are struggling with the above scenario. If you have a better way, I would love to hear about it since my way is a bit tedious.
In a nutshell, in order to have an SSIS package put data from an OLE DB Source into a SharePoint List Destination Lookup Column, you need to pass the ID of the value that is being looked up, not the value that is in the “master” OLE DB source.
Rough explanation, OLE DB Source value for column “Approp” is “4005” --> SQL matches “4005” with the ID in the new lookup table (“4005” = ID “5” as defined in the SharePoint lookup list) --> “5” gets passed into SharePoint List destination lookup
column --> SharePoint displays “4005” and successfully links to the lookup list.
Funny thing (not really), the error(s) outlined in my original post are not related in getting data into a SharePoint Lookup column as I am now successful in getting data into the system but I am still getting the same above error(s). I think it has to do
with the ID column in the SharePoint list destination. What I can’t seem to figure out is why since I am not linking any data to that ID column (at least on new records). I am however linking it on Update and Delete and the errors mentioned above disappear
and things work well.
There are three tasks that need to get done in order to get data from SQL into a SharePoint lookup column assuming you have already set up your SharePoint lookup lists:
1. Create new lookup table(s) in SQL that has the IDs from the SharePoint Lookup list and the values coming from the “master” OLD DB Source. You can see the ID column in SharePoint by toggling it on in a view.
2. Create a SQL command that JOINs all the databases and tables so that the ID is passed and not the value into the SharePoint lookup column
3. Change the “Data access mode” to “SQL Command” instead of the “Table or view” in the OLE DB Source and paste your command into the “SQL command text:” area.
Other helpful info is that you may also need to add additional columns in the new lookup tables in SQL for the scenarios when the data is not unique. You can see this two times in my SQL command example for Units and JobTitles:
SELECT
pps.SSNm,
pps.file_updated,
pps.Employee_id,
/* pps.CheckDistNm,*/
Check_Distribution_id = COALESCE( d.ID, 0 ),
pps.Job_nbr,
pps.SeqNm,
pps.action_eff_dt,
Fund_id = COALESCE( f.id, 0 ),
Appropriation_id = COALESCE( ap.id, 0 ),
ActionCode_id = COALESCE( ac.id, 0 ),
SpecNumber_id = COALESCE( jt.ID, 0 ),
pps.Employee_id,
/* pps.Fund,
pps.Approp,
pps.Unit,*/
Unit_id = COALESCE( u.ID, 0 ),
PosNm,
PosCode,
pps.LastName,
pps.FirstName,
pps.MI
FROM
x_PPS.aReportVw.pps_screens_active AS pps
LEFT OUTER JOIN dbo.DistributionNumbers AS d ON
pps.CheckDistNm = d.Check_Distribution
LEFT OUTER JOIN dbo.Units AS u ON
pps.Fund = u.Fund AND
pps.Approp = u.Approp AND
pps.Unit = u.Unit

Calling webservice in udf for inserting data into webservice

Dear Experts,
      Please give me the drawbacks of using lookup function for inserting data. we are calling a webservice from the udf for inserting the data using a webservice.
It is a file to jdbc usnig a soap lookup . we use this approach because we need to pass the response from webservice along with the error data to the jdbc.   is there any other way to do it without using bpm ?
    In the udf we are creating the xml structure for webservice and passing the parameters through arguments.
is there a better approach for this ?
Thanks,
Aju

Hi Aju,
You can do it without BPM.
Write UDF for Soap Lookup. Parse the response message from Webservice. and map the required values to respective fields.
See the weblog
Webservice Calls From a User Defined Function.
Negative point of this solution is that it will take some time to call Webservice and get response back from it.

Query for inserting data into table and incrementing the PK.. pls help

I have one table dd_prohibited_country. prohibit_country_key is the primary key column.
I have to insert data into dd_prohibited_country based on records already present.
The scenario I should follow is:
For Level_id 'EA' and prohibited_level_id 'EA' I should retreive the
max(prohibit_country_key) and starting from the maximum number again I have to insert them
into dd_prohibited_country. While inserting I have to increment the prohibit_country_key and
shall replace the values of level_id and prohibited_level_id.
(If 'EA' occurs, I have to replace with 'EUR')
For Instance,
If there are 15 records in dd_prohibited_country with Level_id 'EA' and prohibited_level_id 'EA', then
I have to insert these 15 records starting with prohibit_country_key 16 (Afetr 15 I should start inserting with number 16)
I have written the following query for this:
insert into dd_prohibited_country
select
     a.pkey,
     b.levelid,
     b.ieflag,
     b.plevelid
from
     (select
          max(prohibit_country_key) pkey
     from
          dd_prohibited_country) a,
     (select
prohibit_country_key pkey,
          replace(level_id,'EA','EUR') levelid,
          level_id_flg as ieflag,
          replace(prohibited_level_id,'EA','EUR') plevelid
     from
          dd_prohibited_country
     where
          level_id = 'EA' or prohibited_level_id = 'EA') b
My problem here is, I am always getting a.pkey as 15, because I am not incrementing it.
I tried incrementing it also, but I am unable to acheive it.
Can anyone please hepl me in writing this query.
Thanks in advance
Regards
Raghu

Because you are not incrementing your pkey. Try like this.
insert
   into dd_prohibited_country
select a.pkey+b.pkey,
     b.levelid,
     b.ieflag,
     b.plevelid
   from (select     max(prohibit_country_key) pkey
        from dd_prohibited_country) a,
     (select     row_number() over (order by prohibit_country_key) pkey,
          replace(level_id,'EA','EUR') levelid,
          level_id_flg as ieflag,
          replace(prohibited_level_id,'EA','EUR') plevelid
        from     dd_prohibited_country
       where level_id = 'EA' or prohibited_level_id = 'EA') bNote: If you are in multiple user environment you can get into trouble for incrementing your PKey like this.

Is there any better way for updating table other than this?

Hi all, I need to update a row in the table that require me to search for it first (the table will have more than hundred thousands of row). Now, I am using a LOV that will return the primary key of the row and put that primary key to DEFAULT_WHERE property in the block and execute query command to fetch the row that need updating. This works fine except that it require 2-query-trip per update (the lov and the execute_query). Is there any better way to doing this? This update is the main objective for my application and I need to use the most effective way to do it since we need to update many records per hour.

Thanks Rama, I will try your method. Others, how to query row instead of primary key? I thought that querying primary key is faster due to the index?
BTW, what people do if you need to update a table using Form? I have been using the LOV then execute query since I first developing form. But I am building a bigger database recently that I start worrying about multiple query trip to dbms.
FYI my table will have up to million rows on it. Each row will be very active (updated) within 1-2 weeks after it creation. After that it will exist for records purposes only (select only). The active rows are probably less than 1% of all the rows.

Best way to insert data into a non indexed partitioned table?

Hi,
I've a rather basic question that I haven't been able to find an answer to so hope that someone may be able to help.
We need to insert sales data into a partitioned table that is range partitioned on sales date. The incoming sales data can span a number of days, e.g. 31-JUL-2007 through to 04-AUG-2007 inclusive. I've come up with two approaches and would like to know which you would recommend and why?
Approach 1: Load data into each individual partition using a statement like:
INSERT /*+ APPEND */ INTO sales PARTITION (sales_20070731) SELECT * FROM sales_new WHERE sales_date = TO_DATE('31-AUG-2007','DD-MON-YYYY')
Approach 2: Load data into the entire table using a statement like:
INSERT /*+ APPEND */ INTO sales SELECT * FROM sales_new
Thanks

You need to compare both approaches by creating simple test case.
But there is no advantages in approach 1until you will have index on sales_date column.
With index these approaches are comparable and you can choose whatever best fits to your requirements.

Alex

API for insert Lead into telesales

How can Insert lead for customer using API in Telesales

Hi,
Currently, I believe there are no api's to populate the pa_transaction_control table.
If this is a new implementation and you are converting the projects from your legacy system for the first time, you should be able to directly insert date into these tables. This table does not have many FK relationships. Mainly depending on the transaction control is set at the Project or the Task level, you can set the values for Project id /Task id.
I would also suggest that you confirm with Oracle by creating a Tar that there is no API currently available.

Which trigger to use for insert data into db table in Forms

Hi,
My form is current having a database block with table reference. When enter data into form field and click on save button. Automatically the record is inserted into database table.
I want to make this as manual insert. I changed the data block to a non-database. Where should i write the insert statement in order to insert data into table.
Is it Key-commit trigger at form level?
Please advise.
Thanks,
Yuvaraaj.

Hi Yuvaraaj.
Insert should happen when we click on the save which is inbuilt in the form. In this case where should i write the insert statement.Forms in built save commit's the form data where block is based on database not non database.
@2nd reply
Ypu are right. The reason i chnaged the database block to non-database is Currently i have a database block with form field canvas which insert only 1 record in to >table when we click on standard save button. The requirement was to add a field called CHANNEL which should have multiple values displayed. (i created this channel >field in a seperate datablock (non database) and used the same canvas.) When we insert data in all fields (single record) and channel we should be able to selected >multiple channel (say A,B and C) when we click on save then 3 records should be inserted in to the table which looping values for each channel. This was the actual >requirement and this is the reason why iam changing the block to non-database block.You are talking about two blocks.. 1. Master block and 2. Details block name channel
You are inserting one record in master block then insert 3 record name A,B,C for that master record.
Now you want master record should insert to each A,B,C record. Means
'how are you' --master record
and you want
'A'- 'how are you'
'B'- 'how are you'
'C'- 'how are you'OR
?Ok. If you want master record save in database and then want to save non-database(channel) data into database USE Post-Insert trigger at block level and do the rest.
Hope this helps...

Does adobe have alternatives for inserting photos into templates?

I have just downloaded this software in the hope that I can use some template files. They are eps and elements 13 doesn't support it.
In addition to this the only other thing that I wanted elements for was to remove backgrounds. I can't find a tutorial on that. The only one listed is for CC.
The only use I have for the software is to insert photos into a sublimation template. Do Adobe have an alternative that can do this?

Please review this and get back with issues that need additional clarification:

Efficient or Better Ways for Data Declaration

Hi Guys,
Basically I've always programmed much the same way for a pretty long time now. Lately I've been asking myself the question - "how can i start improving on my tried and trusted ways".(oftern a linear programming approach). As part of this I'm examining ways to declare data better within in programs and to adopt a neat way to do so.
This may seem pretty trivial but the first question I want to ask is how to declare data better
e.g. I need to declare constants - each constant corresponds to a rule number; 1, 2,3,4,5,6 - 23 etc.
Instead of declaring the following line 23 times - is there a better way to declare in such a way.
Constants: c_rule_1 type c value '1' ,
                c_rule_2 type c value '2',
                etc etc etc
Your thoughts are greatly appreciated.
Thanks.
DK
Edited by: Damien Kesle on Nov 26, 2008 10:00 AM

Hi,
With my knowledge, data declarations for all constants with DATA comamnd itself is good practise in point of performance. Alternative is dynamic creation of variables. But it consumes more time and is not good to practise. Instead of crating individual parameters for each constant, you could create a structure and add all constants as fields as follows:
constants: begin of con,
                   1 type c value '1',
                   2 type c value '2',
                end of con.
