Hi Guys,
I am very much new SQL and VB, I am trying to add header, details and footer to flat files using VB. Below is the sample script I got it from one of the forum. But I need to replace all the variables with my requirement. Basically, this can be accomplished by creating the header or footer in a separate task, and then prefixing or appending it to the data. . The final output file, which includes the header, data, and footer rows.
Header Field Names: RecordTypeCode, RecordFormatVersionNo,DataDateFileIdentificationCode
Details from source table: LoanID, SourceID, Borrower, SetttlementDate, Repay
Footer: RecordTypeCode, RecordFormatVersionNo,DataDateFileIdentificationCode,DetailRecordCount (This has to be count of records in detail table), controlTotal1
SSIS package : DataFlow 1 (Row Count From source to Flat File) --> DataFlow 2 ( Append Footer through VB Script and place same flat file ) --> Script Component ( Add heater).
I have declared a variable exactly like this in Dataflow
First Data Flow šeg. ETLLoanTableĆ RowCount (I have declared variable here as RecordCount) Ć FlatFileDestination).
Second Data Flow : I am trying to append footer using below script. Below highlighted code need to change according my requirements, please can anyone help me with this.
' Microsoft SQL Server Integration Services user script component
' This is your new script component in Microsoft Visual Basic .NET
' ScriptMain is the entrypoint class for script components
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
<Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute> _
<CLSCompliant(False)> _
Public Class ScriptMain
Inherits UserComponent
Public Overrides Sub CreateNewOutputRows()
Dim recordCount As Integer
Dim vars As IDTSVariables100
'Get the record count
Me.VariableDispenser.LockOneForRead("RecordCount", vars)
recordCount = CType(vars("RecordCount").Value, Integer)
vars.Unlock()
'Output one row with record count
Output0Buffer.AddRow()
Output0Buffer.FooterRow = String.Format("Footer Row Count: {0}", recordCount)
Output0Buffer.SetEndOfRowset()
End Sub
End Class
Third One is just the custome script to Add Header
' Microsoft SQL Server Integration Services Script Task

' The ScriptMain class is the entry point of the Script Task.

Enum ScriptResults
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
End Enum
Public Sub Main()
Dim fileContents As New StringBuilder()
Dim vars As Variables
Dim recordCount As Integer
Dim finalFile As String
'Get the record count
Dts.VariableDispenser.LockForRead("RecordCount")
Dts.VariableDispenser.LockForRead("FinalFile")
Dts.VariableDispenser.GetVariables(vars)
recordCount = CType(vars("RecordCount").Value, Integer)
finalFile = CType(vars("FinalFile").Value, String)
vars.Unlock()
'Write header, then append file contents and write back out.
fileContents.AppendLine(String.Format("Header Row Count 1: {0}", recordCount))
fileContents.Append(File.ReadAllText(Dts.Connections("Destination").ConnectionString))
File.WriteAllText(finalFile, fileContents.ToString())
Dts.TaskResult = ScriptResults.Success
End Sub
End Class

Where do you define your File in the script?
I'm very new to vb and just need to add a static header to my text file, but I don't see where your file is defined.
For instance, I need to add the header 'EXTSYS1|MXOPERLOCInterface|AddChange|EN' to my 'locations.txt' file that I created in my SSIS package.
Thanks!
