Chapter 7: The DataServer Tutorial Table 51: OpenEdge DB to MS SQL Server Conversion Advanced Options (2 of 2) Interface Elements Description For field widths use: When pushing fields to a foreign data source, you can select one of two primary field format options: • Width — Uses the value of the _width field in the _field record. • 4GL Format — Compiles with the current default width specified. (default) If you select the 4GL Format option, you have an additional setting to define: • Expand x(8) to 30 — This setting is on by default to indicate that the format for the character fields defined as x(8) will be created as 30 characters. Note: You cannot use the Expand x(8) to 30 setting with the Width option. Apply Uniqueness as The Apply Uniqueness as allows to you specify how uniqueness is defined. The default, Indexes, provides backward compatibility. The Constraints option defines constraint definitions for uniqueness, but existing constraint definitions always take precedence over any constraint definition generation from this migration option. For Create RECID use: Select either Trigger or Computed Column. Trigger is selected by default. Computed Column is preferred as it offers greater reliability, but is only available for MS SQL Server 2005 and later. Include Defaults The Include Defaults check box is enhanced with an Apply Default as radio set that allows you to specify if you want your defaults defined as Field Attributes (default) or Constraints. The Field Attributes option provides backward compatibility. The Constraints option only defines constraint definitions if a constraint definition doesn't already exist. If the user selects Constraints, then after the migration, all the initial values defined for migration become named default constraint definitions on the server. 298 OpenEdge Data Management: DataServer for Microsoft SQL Server
Migrating an OpenEdge database to MS SQL Server To perform a complete migration of your OpenEdge database to a target data source, you must enter information in all appropriate fields and select all appropriate check boxes. The utility creates a schema holder, updates the empty target data source that you created to contain the objects stored in your OpenEdge database, and creates a startup procedure that you can use to connect your schema holder. The startup procedure derives its name from the logical name for your target database. For example, if you specified “sports” as the logical data source name, the utility creates the csports.p startup procedure. To run the OpenEdge-to-MS SQL Server Conversion utility in batch mode: 1. Create a target MS SQL Server database. You must use an empty target data source when you run the OpenEdge DB to MS SQL Server utility. 2. Configure your ODBC driver to connect to your new target data source. 3. On your client machine, pass parameters to the utility by setting the environment variables listed in Table 52. Table 52: OpenEdge-to-MS SQL Server Conversion utility batch parameters (1 of 3) Environment variable Description PRODBNAME Specify the source OpenEdge database name. PROCONPARMS Specify parameters for the connection to the source OpenEdge database. SHDBNAME Specify the new schema-holder name. MSSDBNAME Specify ODBC data source name. MSSPDBNAME Specify logical database name. MSSUSERNAME Specify the user name for the target data source. MSSPASSWORDnote Specify the password of the user for the target data source. MSSCONPARMS Specify additional connection parameters for the schema holder. MSSCODEPAGE Specify the OpenEdge name for the code page that the ODBC data source uses. By default, the code page for a schema holder is ibm850. You can leave this unset and use the Change DataServer Schema Code Page utility to add the code page information for the schema holder later. MSSCOLLNAME Collation name. MSSCASESEN Yes or No for Code Page case sensitive. COMPATIBLE Create arrays and RECID. Set to 2 for using a computed column and 1 or Yes for using a trigger.
