SSIS：条件拆分结果为变量

Question

I have condition where I need to feed conditional split result based on condition (will be just one int value) to variable. Can some one help how to do this?

My actual package (Data flow):

XML Source --> Conditional split (based on condition) 2 outputs..one result based on condition (will be just one int value) need to pass it on to variable. How to achieve this?

Answer 1

纯SSIS方式-将数据流消耗到Recordset目标中 ，然后使用ForEach循环遍历它，将值分配给所需的变量。

Answer 2

you have to use a script component to achieve this:

• Create a script component ( Choose it's type as Destination )

• Double click on script component and Choose your Variable as a ReadWrite Variable. ( in my example the variable is named Result

• Inside the script window write the following code

   Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) If Not Row.inColumn_IsNull Then Variables.Result = Row.inColumn End If End Sub 

Side Note: Variable value does not change before dataflowtask execution is finish, to use the new value you have to continue your work in another dataflowtask

Answer 3

I know two ways to realize this.

First: Do it with a C# script component, this is the easiest way. Just put a script component behind your conditional split, select your variable as "ReadWrite", then set it like that in the code:

Dts.Variables["yourvariable"].Value = Input0Buffer.Yourcolumn

I don't have access to SSIS right now, so I can't give you the exact code, but this should get you started.

Second: Write to a table and read it back with Execute SQL task. I don't really like this way ;-)
