SQL 2005: SSIS – PUSHING DATA TO MYSQL USING SCRIPT COMPONENT DESTINATION-优快云博客

本文介绍如何使用 SQL Server 2005 Integration Services (SSIS) 将数据从 SQL Server 数据库推送到 MySQL 数据库。通过创建 Script Component Destination 并使用 Visual Basic .NET 编写代码，实现数据插入操作。

SQL 2005: SSIS – PUSHING DATA TO MYSQL USING SCRIPT COMPONENT DESTINATION

Sometimes, I just wonder why things that are useful in previous versions of things get removed. In SQL 2000, in DTS, there was an ODBC destination, you could write (insert, update, etc) to a foreign (non MSFT SQL) system easily. DB2 – no prob, MySQL – heck yea. For whatever reason, in SQL 2005 Integration Services (SSIS), that ability was removed (in SQL 2008 SSIS there is an ADO.NET Destination that can update ODBC sources, so they brought some functionality back).

I need to write to a MySQL database pulling data from a SQL Database, using SSIS 2005. What are the options? Well, the best I could come up with was a Script Component Destination in my DataFlow, this is how I did it:

1) Create a new SSIS Package, throw a DataFlow on the Control Flow, Add your connections (let’s say SourceDB_SQL – your source data, and then DestDB_MySQL – your MySQL destination, it needs to be a ADO.NET Connection, you need to install the MySQL connection – I installed this http://dev.mysql.com/downloads/connector/odbc/5.1.html)

2) In your DataFlow, create your OLEDB Source and get your query returning data, throw a Script Component on the Data Flow and make it a Destination.

3) Open the Script Component, set your input columns up, and then your Connection Manager

4) Open the actual script, and you just have to add a few lines of code:

' 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
Imports System.Data.Odbc
 
Public Class ScriptMain
    Inherits UserComponent
 
    Dim mySQLConn As OdbcConnection
    Dim sqlCmd As OdbcCommand
 
    Public Overrides Sub AcquireConnections(ByVal Transaction As Object)
        mySQLConn = CType(Me.Connections.MySQLDatabase.AcquireConnection(Nothing), OdbcConnection)
    End Sub
 
    Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
 
        sqlCmd = New OdbcCommand("INSERT INTO steve_test(ShipTo, YearValue) VALUES(" & Row.ShipTo & ", '" & Row.YearValue & "')", mySQLConn)
        sqlCmd.ExecuteNonQuery()
 
    End Sub
 
    Public Overrides Sub ReleaseConnections()
        Me.Connections.MySQLDatabase.ReleaseConnection(mySQLConn)
    End Sub
End Class

Run it and you are done! Easy. Now you can write data into MySQL using SQL 2005 SSIS (or any ODBC destination if you can get it to work :))
