    Hi all,

    I couldn't figure it out how to parse the file and load into two SQL table. Source and destination are in SQL. Below are the sample SQL code for Source Sample table/data and destination tables. Please let me know if my question is not clear. I really appreciated.

    Here is my sample Source data
    Source_id,sta_id    ,Address1     ,City     ,PaymentMethod,Invoice_Detail
    21     ,KXV        ,Rd         ,       ,       ,
    22     ,KXV        ,PO Box234    ,Dallas,       ,
    31     ,         ,         ,     ,Cash       ,;8555-4
    42     ,Paid Sat    ,         ,     ,       ,
    Y     ,180217    ,6         ,23550     ,     ,800-345-969
    21     ,CNN        ,TV         ,     ,       ,
    22     ,CNN        ,PO Box 99    ,Chicag,       ,
    31     ,         ,         ,     ,Cash       ,224;86799
    42     ,Paid Sun    ,         ,     ,       ,
    Y     ,180218    ,6         ,3456     ,     ,888-191-1900
    Y     ,180226    ,7         ,456     ,         ,800-900-8999

    Here are my two Destination Tables that I want to load my source file

    Table A
    Destination_Header
    id,Invoice#,Address1 ,City ,Sta_id
    1 ,8555-4 ,PO Box234,Dallas,KXV
    2 ,86799 ,PO Box 99,Chicag,CNN

    Table B
    Destination_Detail
    id,Header_id,Month,Day,Year,Air,Phone#
    1 ,1 ,02 ,17 ,18 ,6 ,800-345-969
    2 ,2 ,02 ,18 ,18 ,6 ,888-191-1900
    3 ,2 ,02 ,26 ,18 ,7 ,800-900-8999

    Please will you show us what you've already tried, because it's not clear where you're stuck?

    The best advice is to change the design - there's no way you should be mixing those two data sets in one table.  But if you're stuck with it, surely you just insert into Destination B all the rows where sta_id is Y, and into Destination A everything else?

    Hi John,
    Thanks for your time to reply. 
    In above code, I missed important source field "Source_ID" that will tell where the batch start and ends.

    John, I was trying to accomplish through SSIS, because my source is .txt. I am not very good in SQL that's the reason I asked for help or show me the right path.

    Thank You!

    Sorry, but you've confused me.  First you said the source is SQL, now you're saying it's .txt.  But if it's .txt, just bring it into a staging table - as you already appear to have done - and manipulate it from there.  If you're not very good in SQL then that's going to be a problem for you.  I'm happy to help out, but I need you to tell me where you're stuck.

    Sorry If I confuse you. Yes, first I said my source is SQL and yes the original source is my .txt. I thought it is easy for me to load the data into STG and do SQL to parse that data. Anyway, Below is the "While Loop" that I am using to parse the data.
    I couldn't figure it out how can I pull One Batch (One Bath start from source_id = '21' to Next source_id = '21') then I can parse the field one by one and load into my destination tables.

    Jon, I am sure now I didn't confuse you more.

    If I can add "RANKID" in my source then I can easily Pull my data through above While Loop. Here is source table as an example.

    RankID,Source_id,sta_id    ,Address1 ,City    ,PaymentMethod,Invoice_Detail
    1          ,21    ,KXV    ,Rd    , ,    ,
    1          ,22    ,KXV    ,PO Box234    ,Dallas,    ,
    1          ,31    ,    ,    ,    ,Cash    ,;8555-4
    1          ,42    ,Paid Sat    ,    ,    ,    ,
    1          ,Y    ,180217    ,6    ,23550    , ,800-345-969

    There is absolutely nothing in your source data to guarantee the order of the data to do any batching or grouping with.  If this is actually starting out as a text file, please attach it along with a record layout and a target table and one of us might be able to show you how to pull this off.

    We also need to know the meaning behind the various Source_IDs and how many of each a "batch" can possibly have.
