Module 11: Data Transport

Overview Tools and functionality in Oracle and their equivalents in SQL Server for: Data transport out of the database Data transport into the database Tools and functionality in SQL Server for data transport into, out of, and within a database and across multiple databases, multiple file formats, and other data sources and destinations

Data Out Overview Oracle 10g SQL Server 2008

Data In Overview Input PartsPayrollPerson SQL Server 2008

Demonstration 1: Exporting Data Using PowerShell In this demonstration you will learn to: Manage data export with PowerShell

SQL Server Data Transport SQL Server offers several Bulk Copy commands and tools: BCP, the Bulk Copy utility, is used to transfer large volumes of data in and out of a database To export—data is dumped into a flat file in a delimited format To import—data is first exported from the source database or program and then imported into SQL Server database BULK INSERT command can be used within Transact-SQL programs to insert large volumes of data from a flat file Bulk copy API can be used in ODBC, OLE DB, SQL-DMO and SMO applications OPENROWSET (BULK…) can also be used to bulk import large object data in SQL Server

Demonstration 2: Bulk Copy and Bulk Insert In this demonstration you will learn to: Extract the data with the Bulk Copy Program (bcp) Use bcp and Bulk Insert to import data into new tables

SQL Server Integration Services (SSIS) SQL Server Integration Services offers several tools to extract, transform and load data from multiple data sources into SQL Server databases and vice versa Provides control over data flow, looping and conditioning Packages can be built using SSIS designer in Business Intelligence Development Studio Import / Export Wizard Database Export Utility

Elements of Integration Services SQL Server Integration Services Service (MsDtsSrvr.exe) Package Control Flow Elements Containers Tasks Precedence Constraints Data Flow Elements Event Handlers Variables Configurations

SSIS Tools SSIS tools are used to create, modify and execute Packages SSIS Import / Export Wizard Assists in building simple Packages to import, export, and transform data or to copy database objects SSIS Designer inside Business Intelligence Development Studio Graphical application that lets us build and debug packages containing complex workflows, multiple connections to heterogeneous data sources, and event-driven logic SSIS Package Execution Utilities dtexecui.exe dtexec.exe dtutil.exe is a tool used to manage SSIS packages

Demonstration 3: SSIS Data Flow In this demonstration you will learn to: Extract conditional table from one source to multiple destinations

Copy Database Wizard Copy Data Wizard (CDW) can be used to copy or move databases across SQL Server instances Provides two methods: Attach / Detach Using SQL Server Management Objects (SMO) A proxy account must be created in order to run SSIS package created by CDW

Demonstration 4: Database Import/Export Wizard In this demonstration you will learn to: Move infrequent data transformations with a wizard

Review We reviewed tools used in Oracle for transferring data out of a database — Data Pump Export utility, SQL*Plus, SBMS_UTILITY and UTL_FILE packages and their SQL Server equivalents — bcp utility, sqlcmd.exe tool, SSIS, print and SELECT statements We have seen tools used in Oracle for transferring data into a database — Data Pump Import utility, SQL*Plus, SQL*Loader and command, SSIS, OPENROWSET We discussed in detail the Bulk Copy commands in SQL Server We discussed SSIS in detail, including: SSIS Package components such as tasks, transformations and workflow constraints SSIS tools such as Import//Export Wizard, SSIS Designer Copy Database Wizard
