You modify the destination database name and the default locations for the database files on the destination server. You also specify how the Copy Database Wizard should react when a database with the requested name already exists on the destination. The options are either stopping the transfer or dropping the existing database and creating a new database with the same name. The wizard will move all the objects and data. On page 6 (Select Server Objects), shown in Figure 44-6, you can optionally direct the wizard to move the following: ■ All logins or only those that have access to the database ■ All or selected non-system stored procedures in the master database that are used by the database ■ All or selected SQL Agent jobs (automated and optionally scheduled tasks) ■ All or selected endpoints ■ All or selected SSIS packages ■ All or selected user-defined error messages (used by the RAISERROR T-SQL command) Click the ellipses button next to each selected option and choose individual objects you want to trans- fer. If you do not choose individual objects, all the objects of each selection option are transferred by default. 1043 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1044 Part VI Enterprise Data Management FIGURE 44-5 Configure the destination database FIGURE 44-6 The Copy Database Wizard can move server-related information as it moves the database 1044 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1045 Transferring Databases 44 Page 7 (Location of Source Database Files), shown in Figure 44-7, asks you to enter the file share containing the source database files. FIGURE 44-7 Select the location of the source database files Page 8 ( Configure the Package), shown in Figure 44-8, shows the package location. You can also provide a name for the package and choose a method for logging errors. The default method uses the Windows event log. It’s also possible to send a list of errors to a text file. The wizard will request a filename when you choose this option. Page 9 (Schedule the Package), shown in Figure 44-9, directs the wizard to either run the Integration Services package once upon completion of the wizard, run it once later, or set it up on a regular schedule. Page 10 (Complete the Wizard), shown in Figure 44-10, shows a summary of the choices you made so far. If you want to change something, you can click Back. If you are satisfied with all the choices, click Finish. When finished, the wizard generates and runs an Integration Services package (see Figure 44-11) and saves it on the destination server. You can open the generated Integration Services job, as shown in Figure 44-12, by selecting the Jobs node under SQL Server Agent (of the destination SQL Server) in the console tree and then double- clicking on the package. If the name was not edited in the wizard’s schedule page, then it should be CDW followed by the two server names and an integer. The creation date i s also listed. 1045 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1046 Part VI Enterprise Data Management FIGURE 44-8 The Copy Database Wizard showing the Integration Services Package location FIGURE 44-9 The Copy Database Wizard can run the Integration Services package once now, once later, or on a schedule 1046 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1047 Transferring Databases 44 FIGURE 44-10 Copy Database Wizard summary page FIGURE 44-11 When the Copy Database Wizard creates the Integration Services package, it displays its progress as it works its way through t he steps 1047 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1048 Part VI Enterprise Data Management FIGURE 44-12 Job properties for the Integration Services package created by the Copy Database Wizard Working with SQL Script Of the four methods for moving a database, running a SQL Script, or batch, is the only method that creates a new database. Perhaps it’s false logic, but the idea of starting with a fresh installation at a client site, without any residue from test data, is a reassuring thought. Scripts are smaller than databases. T hey often fit on a floppy, and they can be edited with Notepad. For example, the sample databases for this book are distributed by means of scripts. Scripts are useful for distributing the following: ■ Database schema (databases, tables, views, stored procedures, functions, and so on) ■ Security roles ■ Database jobs ■ Limited sample data or priming data Though it’s possible, I don’t recommend creating a script to move the following: ■ Data: A script can insert rows, but this is a difficult method o f moving data. ■ Server logins: A script can easily create server logins, but server logins tend to be domain specific, so this option is useful only within a single domain. 1048 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1049 Transferring Databases 44 ■ Server jobs: Server-specific jobs generally require individualized tweaking. While a script may be useful to copy jobs, they will likely require editing prior to execution. Scripts may also be used to implement a change to a database. The easiest way to modify a client databaseistowriteascript.Thechangescript can be tested on a backup of the database. Scripts may be generated in several ways: ■ The database can be developed initially in Management Studio using a handwritten DDL script. Chapter 20, ‘‘Implementing the Physical Database Schema,’’ explains how to create such a script. In addition, the sample databases on the website are all created using a DDL script. This is my preferred method. The code for this chapter may be downloaded from the book’s website at www.sqlserverbible.com. ■ Management Studio can generate a script to create the entire database or a c hange script for schema changes made with the Table Designer or the Database Designer. ■ Most third-party database-design tools generate scripts to create the database or apply changes. With a focus on generating scripts with Management Studio, open the Management Studio script genera- tor; select the database in the console tree, right-click, and select Tasks ➪ Generate Scripts. Skip the Welcome to the Generate SQL Server Scripts page. In Management Studio’s Script Wizard, use the Select Database page, shown in Figure 44-13, to select the database that you want to script. If you want to script all objects, then check ‘‘Script all objects in the selected database.’’ The Choose Script Options page, shown in Figure 44-14, contains two sets of options. The General options determine script behavior, such as whether Management Studio appends the new script to an existing script file. The Table/View options determine script features, such as whether the script contains code to create foreign keys. The Choose Object Types page, shown in Figure 44-15, contains a list of objects within the selected databases. At a minimum, you’ll see an option to script tables. Note that you will not see this page if you previously checked ‘‘Script all objects in the selected database’’ in the Select Databases page. The pages that follow vary depending on the objects you select. For example, if you choose to script tables, then you’ll see a Choose Tables page in which you select the tables you want to script. Eventually, you’ll reach the Output Option page, shown in Figure 44-16. Use the options on this page to select an output method. If you choose the Script to File option, then you’ll also need to choose the output filename and output format. The next page (Script Wizard Summary) shows a summary of the choices that were made so far. If you want to change something, you can click Back. If you are satisfied with all the choices, click Finish. 1049 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1050 Part VI Enterprise Data Management FIGURE 44-13 Management Studio can generate scripts for any of the databases within the DBMS FIGURE 44-14 Set the script options to match the database features you require and to define the behavior you expect from Management Studio 1050 www.getcoolebook.com Nielsen c44.tex V4 - 07/21/2009 2:34pm Page 1051 Transferring Databases 44 FIGURE 44-15 Select the object types FIGURE 44-16 Choose an output option that matches the kind of database transfer you want to perform 1051 www.getcoolebook.com . the destination server.
