Connect/Repair Wizard: Discover and Define SQL Relationships
If the Database Connection Wizard detects that any tables have no indexes and have not been specified as System Tables, you will be prompted to select column(s) to create at least one "DataFlex Side Index".
See Index Keywords for more information about how indexes are defined and used when connecting to database tables.
Note
Adding a DataFlex side index to a table can result in poor performance. It is strongly recommended to add at least one index directly to the database table using the native tools. Speak to your DBA for additional information.
