Creating SQL Server Agent Jobs

  • 아티클

Microsoft SQL Server의 이후 버전에서는 이 기능이 제거됩니다. 새 개발 작업에서는 이 기능을 사용하지 말고, 현재 이 기능을 사용하는 응용 프로그램은 수정하십시오.

These examples illustrate creating SQL Server Agent jobs.

Use SQL Distributed Management Objects (SQL-DMO) to create a SQL Server Agent job by:

  • Creating and populating a Job object.
  • Adding the Job object to the Jobs collection of a JobServer object.
  • Creating and populating one or more JobStep objects.
  • Altering the Job object, by adding the JobStep object(s) created to the JobSteps collection.

With the job created, indicate an execution target. For more information about examples, see Targeting SQL Server Agent Jobs.

[!참고] SQL Server Agent implements executable subsystems for job steps. The text defining the administrative task is interpreted by the selected executable subsystem. In the examples that follow, all job steps in the job created by the example use a single executable subsystem. This implementation is imposed for clarity only.

Examples

A. Creating a Job Containing a Transact-SQL Command Batch

This example illustrates creating a multistep job. Each job step is defined by using a Transact-SQL command batch.

This example:

  • Creates a Job object and adds the object to a Jobs collection to create a SQL Server Agent job.

  • Gets the Tables collection of a Database object.

  • For each Table object in the collection:

    • Creates a JobStep object.
    • Uses the Name property of the Table object to build a Transact-SQL command batch to set the Command property of the JobStep object.
    • Builds default job control-of-flow logic.
    • Adds the JobStep object to the JobSteps collection of the Job object.

  • Assigns a starting step for the job and adjusts logic for the final step.

  • Commits job modifications.

    ' Table object used in iteration over Tables collection.
Dim oTable As SQLDMO.Table

Dim oJob As New SQLDMO.Job
Dim oJobStep As SQLDMO.JobStep
Dim idStep As Integer

' Create the SQL Server Agent job. Job will perform an update
' of all optimizer-supporting data distribution statistics.
oJob.Name = "Northwind_Statistics_Update"
oSQLServer.JobServer.Jobs.Add oJob

' Alter the job, adding job steps and setting starting step.
oJob.BeginAlter

' Each JobStep contains the Transact-SQL command batch
' updating statistics for a table.
idStep = 0
For Each oTable In oSQLServer.Databases("Northwind").Tables
    ' Only applies to user defined tables....
    If oTable.Attributes <> SQLDMOTabAtt_SystemObject Then
        Set oJobStep = New SQLDMO.JobStep

        idStep = idStep + 1

        oJobStep.Name = "Northwind_Statistics_Update_Step_" & idStep
        oJobStep.StepID = idStep

        oJobStep.DatabaseName = "Northwind"
        oJobStep.SubSystem = "TSQL"

        ' TSQL uses the [] syntax to quote table identifers.
        oJobStep.Command = "UPDATE STATISTICS [" & oTable.Name & _
            "] WITH FULLSCAN, NORECOMPUTE"

        ' Default logic. Amended below.
        oJobStep.OnFailAction = SQLDMOJobStepAction_QuitWithFailure
        oJobStep.OnSuccessAction = SQLDMOJobStepAction_GotoNextStep

        oJob.JobSteps.Add oJobStep
    End If
Next oTable

' Reset the logic flow for the last job step to indicate success.
oJob.JobSteps.ItemByID(idStep).OnSuccessAction = _
    SQLDMOJobStepAction_QuitWithSuccess

' Set the starting step for the job.
oJob.StartStepID = 1

' Alter the job.
oJob.DoAlter

B. Creating a Job Containing an Operating System Command

This example illustrates creating a single-step job. The job step is defined by using an operating system command.

This example:

  • Creates a Job object and adds the object to a Jobs collection to create a SQL Server Agent job.

  • Creates a JobStep object.

  • Assigns the Command and SubSystem properties to indicate an operating system command.

  • Adds the JobStep object to the JobSteps collection of the Job object.

  • Assigns a starting step for the job and job logic.

  • Commits job modifications.

    Dim oJob As New SQLDMO.Job
Dim oJobStep As New SQLDMO.JobStep

Dim strQuote As String

strQuote = Chr$(34)

' Create the SQL Server Agent job. Job will send a network
' popup message.
oJob.Name = "NetSend"
oSQLServer.JobServer.Jobs.Add oJob

' Alter the job, adding job steps and setting starting step.
oJob.BeginAlter

' The job is implemented using a single step.
oJobStep.Name = "NetSend_1"
oJobStep.StepID = 1

' Set the job step exucatable subsystem. For operating
' system command job steps, the subsystem is "CmdExec"
oJobStep.SubSystem = "CmdExec"

' Job step script is:
'
' Net Send SEATTLE1 "Now is the time for all good men " & _
'    "to come to the aid of the party."
oJobStep.Command = _
    "Net Send SEATTLE1 " & strQuote & _
    "Now is the time for all good men to come to the " & _
    "aid of the party." & strQuote

' Logic for a single-step job.
oJobStep.OnFailAction = SQLDMOJobStepAction_QuitWithFailure
oJobStep.OnSuccessAction = SQLDMOJobStepAction_QuitWithSuccess

oJob.JobSteps.Add oJobStep

' Set the starting step for the job.
oJob.StartStepID = 1

' Alter the job.
oJob.DoAlter

C. Creating a Job Containing an Active Script Command

This example illustrates creating a single-step job. The job step is defined by using a Microsoft ActiveX script language.

This example:

  • Creates a Job object and adds the object to a Jobs collection to create a SQL Server Agent job.

  • Creates a JobStep object.

  • Assigns the Command, SubSystem, and DatabaseName properties to indicate an ActiveX language script.

  • Adds the JobStep object to the JobSteps collection of the Job object.

  • Assigns a starting step for the job and job logic.

  • Commits job modifications.

    Dim oJob As New SQLDMO.Job
Dim oJobStep As New SQLDMO.JobStep

Dim strNewLine As String
Dim strQuote As String

strNewLine = Chr$(13) & Chr$(10)
strQuote = Chr$(34)

' Create the SQL Server Agent job. Job will perform an update
' of all optimizer-supporting data distribution statistics.
oJob.Name = "Northwind_Statistics_Update_ActiveScript"
oSQLServer.JobServer.Jobs.Add oJob

' Alter the job, adding job steps and setting starting step.
oJob.BeginAlter

' Define the job's single step.
oJobStep.Name = "Northwind_Statistics_Update_ActiveScript_1"
oJobStep.StepID = 1

' Set the job step executable subsystem. For ActiveX Script
' job steps, the DatabaseName property records the script
' interpreter selected.
oJobStep.SubSystem = "ActiveScripting"
oJobStep.DatabaseName = "VBScript"

' Job step script is:
'
' Set oSQLServer = CreateObject("SQLDMO.SQLServer")
'
' oSQLServer.LoginSecure = True
' oSQLServer.Connect
'
' oSQLServer.Databases("Northwind").UpdateIndexStatistics
'
' oSQLServer.DisConnect
' Set oSQLServer = Nothing

oJobStep.Command = _
    "Set oSQLServer = CreateObject(" & _
    strQuote & "SQLDMO.SQLServer" & strQuote & ")"

oJobStep.Command = oJobStep.Command & strNewLine & strNewLine

oJobStep.Command = oJobStep.Command & _
    "oSQLServer.LoginSecure = True"

oJobStep.Command = oJobStep.Command & strNewLine

oJobStep.Command = oJobStep.Command & _
    "oSQLServer.Connect"

oJobStep.Command = oJobStep.Command & strNewLine & strNewLine

oJobStep.Command = oJobStep.Command & _
    "oSQLServer.Databases(" & strQuote & "Northwind" & _
    strQuote & ").UpdateIndexStatistics"

oJobStep.Command = oJobStep.Command & strNewLine & strNewLine

oJobStep.Command = oJobStep.Command & _
    "oSQLServer.DisConnect"

oJobStep.Command = oJobStep.Command & strNewLine

oJobStep.Command = oJobStep.Command & _
    "Set oSQLServer = Nothing"

oJobStep.Command = oJobStep.Command & strNewLine

' Logic for a single-step job.
oJobStep.OnFailAction = SQLDMOJobStepAction_QuitWithFailure
oJobStep.OnSuccessAction = SQLDMOJobStepAction_QuitWithSuccess

oJob.JobSteps.Add oJobStep

' Set the starting step for the job.
oJob.StartStepID = 1

' Alter the job.
oJob.DoAlter
