OpenEdge Data Management: DataServer for Microsoft SQL Server

Updating a schema holder
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 Table Definitions utility allows you to:
• Add object definitions from the data source to a schema holder. Use this option if
you add a new table, stored procedure, or view to the data source data definitions
and want the schema holder to reflect the change.
• Update existing object definitions in a schema holder to reflect a change in the
supporting data-source object definitions. For example, an integer data type that
is pulled from a MS SQL Server data source can be mapped to any of the following
OpenEdge data types: INTEGER, DECIMAL, LOGICAL, or INT64. See the “Data
types” section on page 71 for more information about support for MS SQL Server
data types and their equivalent OpenEdge data type mapping options.
To update a schema holder from the Data Administration tool:
1. Access the Data Administration, 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 and select data type options as
required. These values preselect the data source objects that the utility uses to
update the schema holder. By default, the wild card symbol (*) appears; it
specifies that the utility uses all of the objects in the data source. For more
information on data type options,
Note: You should not specify an entry that consists exclusively of wild cards for each
of the three entry fields in the dialog box. An entry that consists exclusively of
wild cards might degrade the performance of the database when you perform
a schema pull. (It will include system catalog files from the data source not
typically included in user databases.)
