Updating a Schema Holder

The Update/Add Table Definitions utility allows you to update a schema holder to reflect changes that you make to the data definitions in your data source.

NOTE: Using this utility to update the schema holder is the only way to make sure that your applications can access modifications or additions to a data source.

The Update/Add utility allows you to:

To update a schema holder, follow these steps:

  1. Access the Progress Data Administration tool, if you are not already there, and select DataServer MS SQL Server Utilities Update/Add Table Definitions. The following dialog box appears:
  2. Type preselection criteria values into the fields as required. These values preselect the data source objects that the utility uses to update the schema holder. By default, the wildcard symbol (*) appears; it specifies that the utility uses all of the objects in the data source.
  3. NOTE: For each of the three entry fields in the dialog box, if you enter a value that consists only of wild cards, you might degrade the performance of the database when you perform a schema pull. (It will include system catalog files that are not typically included in user databases.)

  4. Choose OK. A dialog box lists the objects and table information that you have preselected, for example:
  5. Select the objects that you want to update, then choose OK. When the update completes, Progress returns to the Data Administration main window.

When the update completes, Progress reminds you to check the ds_upd.e file. This file contains information about the tables that did not support record IDs as well as other warnings.

When you update a definition, Progress overwrites the old definition with the new one based on the current data source object. It also preserves the Progress-specific table information. As a result, if you want to add a new column to a table in your data source and then update the definition, you do not have to re-enter all of the Progress-specific information for the previously existing columns (fields) in the definition.

NOTE: When you update a table in the schema holder with the Update/Add Table Definitions utility, the information for the user-defined ROWID is lost. You must reselect an index to support the ROWID.
