Great code, simpler than the others I came across, including MSN’s !
The only problem I had was that the connection is case sensitive!

I\’m a rookie in SSIS.

Is it also possible with this script to use mult-value-parameters?

I need to add a condition in a conditional split like \’country in @countries\’.
Should the parametervalue one string like \’UK, Spain, Belgium\’
or should I add a record for each country where the parametername is the same
in every record?

Thanks,

Marc

This will attempt to handle the casting for you from the value retrieved from the database to the correct data type of the variable in the package. So if the value in the database is a numeric stored in a varchar field and the variable data type in the package is an Int32, this will do the parsing and set the variable value successfully.

vars(de.Key).Value = Convert.ChangeType(de.Value, vars(de.Key).DataType)

Don’t forget that the Mor% – sorry, the Cre& – sorry, the swell guys at Microsoft managed to localize the name of the default namespace. I’d bet this accounts for at least some of the other commenters’ problems.

And by the way, I prefer doing this in a data flow like:
Public Class ScriptMain
Inherits UserComponent

Dim oRegEx As Regex

Public Sub New()
oRegEx = New Regex(“[^a-zA-Z0-9_]+”)
End Sub

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim iKey As Int32
Dim sName As String
Dim vars As IDTSVariables90 = Nothing

If Not Row.ikey_IsNull AndAlso Not Row.gname_IsNull AndAlso Not Row.tname_IsNull Then
iKey = CType(Row.ikey, Int32)
sName = oRegEx.Replace(Row.gname, “_”).Replace(“__”, “_”) & “::” & oRegEx.Replace(Row.tname, “_”).Replace(“__”, “_”)
Try
Me.VariableDispenser.LockForWrite(sName)
Me.VariableDispenser.GetVariables(vars)
Catch ex As Exception
Me.ComponentMetaData.FireWarning(1001, “Parameter Reader”, sName & ” not found.”, Nothing, 0)
End Try
If Not vars Is Nothing Then
Try
vars(sName).Value = iKey
Me.ComponentMetaData.IncrementPipelinePerfCounter(103, 1)
Catch ex As Exception
End Try
vars.Unlock()
End If
End If
End Sub

End Class

- Note I thought performance impact of locking/unlocking the vars one by one is negligible, and that this pipeline comes with the fields ikey int, gname wstr and tname wstr, and that I only needed integer parameters in this case.
- Also note the error handling is not clean – am fighting the docs tring to find the specific exception type thrown for a missing name and losing.
- Also note the names in the database are not under my control, hence the sanitizing RegEx.

Make sure that the variable names in the package and in the table match exactly including casing: if you have a “myVariable” in the table and a “MyVariable” in the package then they will not match.
Also, the Variables collection is empty because you do not supply any variables in the script component’s ReadOnlyVariables or ReadWriteVariables, which is good because the script is supposed to be generic. It looks for any variable defined in the package.

I tried the samething in my script task. It neither returns any error nor returns desired results. While debugging I found the variables collection count is always getting displayed as 0 inspite of variables declared at the package level scope. Any help will be appreciated.

Thanks,
