Configuration of SSIS

  • SSIS 64bit oder 32bit
    • Switch package from 64bit to 32bit
  • TargetServerVersion
    • How to change TargetServerVersion of my SSIS Project

Variables

  • Escape Variables
    • Example: “C:\\Test\\File”+ (DT_WSTR, 10)(DT_DBDATE) GETDATE()+”.txt”
    • Handling escape sequences in SSIS Expression string literals
    • Online Excape Text

Control Flow

Ein SSIS Paket besteht aus einer Ablaufsteuerung (Control Flow) und optional (jedoch meist vorhanden) mehreren Daten Flows (Data Flows). SSIS bietet 3 Elemente der Ablauf Steuerungselemente (Control Flow):

  • Container – für die Strukturen der Pakete
  • Tasks – wie beispielsweise File System Task
  • Precedence Constraints (Rangfolgenbeschränkungen) – für die Ablaufsteuerung

Tasks

File System Task

File System Task

Script Task

Send Email Task

Execute SQL Task

Web Service Task

Analysis Services Processing Task

Container

Allgemeines

  • Schleifen
    • Foreeach – Schleifen
    • For-Schleifen / For Loop Container
      • Loop Container (Schleife, die hochzählt)
      • Configure the SQL Server Integration Services For Loop Container
    • Sequenzcontainer / Sequence Container

For Loops (for i = 1 to X)

Foreach Loop (Foreach X in Y)

Sequence Container

  • Sequence Containers in SSIS packages
  • Parallel Execution of Tasks in SSIS

Precedence Constraints (Rangfolgenbeschränkungen)

Precedence Constrains (Rangfolgenbeschränkungen) dienen der Ablaufsteuerung in SSIS Pakete. Sie steuern welcher nächste Task bzw. Container nach der erfolgreichen/fehlerhaften Ausführung eines anderen Tasks bzw. Containers ausgeführt wird. Zusätzlich kann das Eintreten bestimmter Ereignisse die Ablaufsteuerung beeinflussen.

Data Flow Task (Datenfluss)

Bei den Data Flow Tasks handelt es sich um eine spezielle Form des Task, der dazu dient Daten von einer Quelle (Source) in ein Ziel (Destination) zu befördern. Hierbei handelt es sich in der Regel um sogenannte ETLs (Extract-Transform-Load) Prozesse. Sie stellen in der Regel das Kernstück des SSIS Paketes dar, sofern SSIS als ETL verwendet wird.

Extracting and Transforming Data in SSIS

SSIS is the main on-premises ETL (Extract, Transform, and Load) tool from Microsoft, and it’s heavily utilized for data engineering on SQL Server. In this course, you’ll learn how to install and configure SSIS, and develop ETL packages with it.

SQL Server Integration Services

SQL Server Integration Services (SSIS) is one of the core add-on components to SQL Server. With SSIS, professionals can create automated workflows that streamline the process of consolidating data from a wide variety of sources. Through a process called ETL—extract, transform, and load—you can ingest and move data between systems such as other databases, flat data files, and even online repositories. In this course, Adam Wilbert helps you get up and running with SSIS. Adam shows how to work with different control flow tasks, data sources, connections, and transformations. Plus, see how to add variables to control package execution, run packages with T-SQL, and more.
