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 2–17 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: Consider whether you will choose to perform a schema pull that consists only of
wild cards. Doing so might degrade your database’s performance as the activity
will include system catalog files that are not typically included in a user database.
