Info

Chapter 7: The DataServer Tutorial 2. Provide the information described in Table 53. Table 53: Generate Delta.sql OpenEdge to MSS utility (1 of 3) Interface element Description Delta DF File The name of the delta.df file that was created when you ran the incremental dump routine against two OpenEdge databases. You can browse for the file name by choosing the Files button. Schema Holder Database The name of the schema holder. The schema information must match the schema of the MS SQL Server database to be updated. Progress Software Corporation recommends that you are connected to the schema holder. Connect parameters for Schema Specify these parameters to connect to the schema holder if you are not already connected. Logical name for MSS Database Specify the MS SQL Server database logical name, that is, the name by which you refer to the MS SQL Server database in your application. MSS Object Owner Name Specify the name of the MSS database object owner. Maximum Varchar Length By default, the maximum size of the VARCHAR data type is 8000. The text data type is greater than 8000. If you enter a value that is less than 8000, the text data type will be used when a character field display format or width is greater than the value you have entered. Create RECID field Leave this check box selected to obtain the cursor scrolling capability. Include Default Select this check box if you want the OpenEdge initial value used as the default SQL script. Create Shadow Columns MS SQL Server is case insensitive by default, and this box is unmodifiable. When SQL Server is configured with a case sensitive code page, this box is available for selection. Selecting it provides case insensitivity compatible with the behavior of an OpenEdge database. 304 OpenEdge Data Management: DataServer for Microsoft SQL Server
Delta df to MS SQL Server Incremental Schema Migration utility Table 53: Generate Delta.sql OpenEdge to MSS utility (2 of 3) Interface element Description Create schema holder delta df Select this check box if you want the utility to generate a .df file that includes the incremental schema information. You can then load this .df file into the schema holder. By default, this check box is selected. Use Unicode Types Maps character fields to Unicode data types. Only applies if schema image’s code page is UTF-8. Use revised sequence generator Select to enable revised generator and to prevent lock timeouts. Leave unselected to retain older sequence generator, particularly if SET-VALUE sequence statement is used extensively in your program. Map to MSS Datetime Type Selected by default. Uncheck box to map to datetime data types with time zone components. For details, see “DataServer for MS SQL Server support for datetime data types” section on page 76. Expand width (utf-8) Doubles the size of character fields based on specified field width criteria. OpenEdge Data Management: DataServer for Microsoft SQL Server 305
