Deleting an existing constraint definition
Once you have defined a constraint definition, you can delete it. The following
procedures demonstrate how to delete all constraint definitions or one class of
constraint definitions.
To delete one constraint definition:
1. Start Data Administration and connect to the OpenEdge database you are
migrating.
2. Select DataServer→ MS SQL Server Utilities→ Server Attributes→
View/Maintain Foreign Constraints. The View/Maintain Foreign Constraint
Definitions dialog box appears.
3. Select the table and constraint definition you want to delete.
4. Click Delete Constraints to delete the selected constraint definition.
To delete all constraint definitions or all of a particular type of constraint
definition:
1. Start Data Administration and connect to the OpenEdge database you are
migrating.
2. Select DataServer→ MS SQL Server Utilities→ Server Attributes→ Delete
Constraints. The Delete Constraints dialog box appears, as shown in Figure 22.

3. Select the Constraint type, either ALL or a specific sub-set.
4. Click OK to delete the constraint definitions. You are prompted to confirm your
decision. Click Yes to delete the constraint definitions or Cancel to exit without
deleting the constraint definitions.
Generating constraint definitions from ROWID
During the pull phase of a schema migration, choosing Select ‘Best’ ROWID Index
with Foreign Schema, defers to the server API to determine the “best” index choice.
The best index choice is based on many factors specific to the server and may provide
insight into the server benefits of a particular index selection for ROWID.
You can choose to re-migrate your OpenEdge schema based on the previously derived
ROWID designations, by using one of the following:
