在SSIS中使用源脚本组件,我试图检索依赖于表的所有对象的详细信息。到目前为止,我有对象类型和名称,但无法检索架构。有谁知道如何在SMO中实现这一目标?
我的脚本组件代码是:
' 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 Microsoft.SqlServer.Management.Smo
Imports Microsoft.SqlServer.Management.Common
Public Class ScriptMain
Inherits UserComponent
Public Overrides Sub CreateNewOutputRows()
'
'
'
Dim TargetSQLServer As Server
Dim TargetDatabase As Database
Dim TargetTable As Table
Dim uc As New UrnCollection()
Dim dw As New DependencyWalker
Dim dt As DependencyTree
Dim dc As DependencyCollection
Dim dcn As DependencyCollectionNode
Dim sp As New Scripter
Dim outputString As String
TargetSQLServer = New Server("localhost")
TargetDatabase = TargetSQLServer.Databases("AdventureWorks")
For Each TargetTable In TargetDatabase.Tables
' Exclude these objects
If TargetTable.IsSystemObject = False Then
uc = New UrnCollection()
uc.Add(TargetTable.Urn)
sp = New Scripter
sp.Server = TargetSQLServer
' Get dependencies
dw = New DependencyWalker
dw.Server = TargetSQLServer
dt = dw.DiscoverDependencies(uc, DependencyType.Children)
sp = New Scripter(TargetSQLServer)
dc = New DependencyCollection
dc = sp.WalkDependencies(dt)
outputString = ""
For Each dcn In dc
Me.Output0Buffer.AddRow()
Me.Output0Buffer.Database = TargetDatabase.Name.ToString
Me.Output0Buffer.Table = TargetTable.Name.ToString
outputString = dcn.Urn.ToString
Me.Output0Buffer.Dependency.AddBlobData(Text.Encoding.GetEncoding(1252).GetBytes(outputString))
Me.Output0Buffer.ObjectType = dcn.Urn.Type.ToString
outputString = dcn.Urn.GetNameForType(dcn.Urn.Type.ToString).ToString
Me.Output0Buffer.ObjectName.AddBlobData(Text.Encoding.GetEncoding(1252).GetBytes(outputString))
outputString = ""
Me.Output0Buffer.Schema.AddBlobData(Text.Encoding.GetEncoding(1252).GetBytes(outputString))
Next
End If
Next
End Sub
End Class

嘿ekoner,
我有工作代码遍历数据库中的依赖树,并通过简单的字符串解析解决了问题。
您的骨灰盒将以
的形式返回///StoredProcedure[@Name='uspUpdateEmployeeHireInfo' and @Schema='HumanResources']
只需解析@Name,然后解析@Schema。
下载DBSourceTools的源代码:http://dbsourcetools.codeplex.com
看看DBSourceToolsLib.SysObjects.UrnParser
还有DBSourceToolsLib.SysObjects.SODependencyTree用于工作示例。
