Passing Object Variable as input parameter to an Execute SQL Task Query

I've encountered a new problem with an SSIS Pkg where I have a seq. of Execute SQL tasks. My question are:

1) In the First Execute SQL Task, I want to store a single row result of @.@.identity type into a User Variable User::LoadID of What type. ( I tried using DBNull Type or Object type which works, not with any other type, it but I can't proceed to step 2 )

2) Now I want to use this User::LoadID as input parameter of What type for the next task (I tried using Numeric, Long, DB_Numeric, Decimal, Double none of there work).

Please give me solutions for the above two..

@.@.IDENTITY returns an integer, so your variable type should be Int32. This may help - http://www.sqlis.com/58.aspx|||

Darren,

Thanks for your solution,

Still Execute SQL query task fails if I use Int32 type for the @.@.identity single row result Variable.

When I set it to dbnull it works however it's unable to use this Value as an input paraemter for the next Execute SQL task.

Moreover I want the solution for the step 2 as well|||

@.@.IDENTITY returns a numeric, not an integer. (http://msdn2.microsoft.com/en-us/library/aa933167(sql.80).aspx)

Just cast it to an integer and all will be well.

select cast(@.@.IDENTITY as int) as 'Ident'|||

Thanks Phil,

It seems that both of your solution will work here. Returns numeric so we can use int32 variable for assigning the result. Came to know that when we use int32 variable as an input parameter to another Execute SQL task, we declare it Long type.

There is one more issue i couldn't resolve. There is a type mismatch when I use to map String Variable as input Parameter to a Varchar type in Execute SQL Task. As such Execute SQL task Fails.

Under Parameter Mapping

User:: StrVar Varchar 0

However When I directly assign the String value in place of the parameter it works.

Select SrcRowCount AS CntLoadID From LoadDetails Where Source = ? ( Replacing this value '32, 2323, 2343,23434' works)

Is there any work around for this?

That works for me, using OLE DB connection though. What type of connection are you using?

Hi Rafael,

I am using OLEDB connection.

When I create an expression: Left(sqlstatement)+@.[user::CntLoadID] + Right(sqlstatement), it works indeed. But it seems an alternate way.

Pass back error count to Parent pkg

I am trying to pass back the number of errors encountered by a child package to the Parent package. I have a script within the child package, which will set the value of the Parent package's variable (ChildErrCount). However, I have no idea how to access the Child package's Errors collection to get a count.

Any ideas? Has someone figured out a way to reference the current package's properties (besides what's available from Dts.* ?

Thanks!

Why don't you want to use the error information available through dts.*?

Here is a useful link (although it uses the dts.* approach):

NOTE: you can then push these values to a variable and pass it up to the parent package...

OK, ignore any parent/child aspects of my question.

Let's say your package has a bunch of errors, and sometimes you get a warning message:

The Execution method succeeded, but the number of errors raised (6) reached the maximum allowed (1);

I want to know how to get that "6" value, (i.e. I don't need to know any specific error info). It's obviously stored within the package -- I just want access to it.

Initially I was thinking I could code my way into the Package and retrieve the Errors Collection; then use its Count property:

CurrentPackage.Errors.Count

But, there's no easy way to do that, which is why I'm here.

|||

You could put something in the OnError eventhandler that simply increments a variable every time it executes.

If another way exists, I don't know about it. perhaps Microsoft do. [Microsoft follow-up]

The Package object support the "Errors" property which you can call the "Count" method. Unfortunately you cannot get access to the package object inside script task. This is a design decision. The only way to get to property is via the programming object model.

I am not aware of any workaround beside Jamie's suggestion.

|||Since you are calling this from a parent package, you could run the child package through a script task, instead of the Execute Package task. That way, you could access the Package.Errors property of the child package.|||

That's a neat idea, John. I hadn't thought of that. I was hoping to avoid recalculating a count that already existed, but for now Jamie's workaround seems to be the simplest solution so I'll go with that.

Thanks to all!
