how to insert more than once when processing one row in script component

I am trying use call DirectRowToOutput0 more than once to achieve the goal, but it gives an error of calling COM. I can create more than one destination to achieve it, but I need create 8 destinations for my situation. Is there any easy way?

Thanks

Is this any help to you: http://blogs.conchango.com/jamiethomson/archive/2005/09/05/2113.aspx

|||no, that is not what I am trying to do. In fact, I need insert to the same destination more than once.|||

In that case this will be an asynchronous component. You will then be able to do what you want with the rows.

How to impletement this query in SSIS package

Is there component in SSIS Package that I can use SQL Statement to update input dataset column based on a join query with a table?

update <input dataset> set column01 = -1
where column01 not in (select column from dbo.columnlist)
and column01 <> -1

Perhaps a combination of derived columns, conditional statements, and merge joins (perhaps).|||

Hi Phil,

if I can't not write SQL script to impletement this, I have to use condition split (for column01<>-1 ) -> Sort->Merge Join(Join dbo.columnlist table )->Condition Split (column from dbo.columnlist is null), derived column (update column01 with -1) -> Union All.

it looks so complicated.

do you know is there any component that we can write script to update the input column set? I know we can use VBScript component to do this , but I'm wondering if we can use SQL Script.

|||I think you should perform a lookup transformation against "select column from dbo.columnlist".

Using the lookup error output, you can add a derived column that sets column01 to -1. Then, use a union all to join the normal lookup output with its error output.

Don't worry about the "and column01 <> -1" statement. It is worthless.|||

how could I impletement "Not in (select column from columnlist )" in a lookup component?

a lookup component can only use equal join.

I tried with 'enable memeory restriction' and modify the SQL Statement , replacing the '=' with '<>', but it prompts error when I debug, saying 'no match rows', but actually I do have match rows.

Right, which is why I said to use the error output. For every input row that isn't in the lookup, it'll go down the error output (the red arrow).
