Configuring Constraints

Configuring Constraints

You can add constraints to relational data objects, flat file data objects, customized data objects, logical data objects, and virtual tables. After you add a constraint, you can edit or delete the constraint.
  1. From the
    Object Explorer
     view, open the mapping that contains the relational data object added as a Read transformation. Or, open the flat file data object, customized data object, logical data object, or virtual table.
    • To set constraints on a relational data object added to a mapping as a Read transformation, select the Read transformation in the mapping. On the
      Properties
       view, select the
      Advanced
       tab.
    • To set constraints on a flat file data object, select the
      Advanced
       view and expand the
      Run-time: Read
       section.
    • To set constraints on a customized data object, select the
      Read
       view and select the
      Output
       port of the source transformation. On the
      Properties
       view, select the
      Advanced
       tab.
    • To set constraints on a logical data object, select a logical data model and select the logical data object. On the
      Properties
       view, select the
      Advanced
       tab.
    • To set constraints on a virtual table, open the virtual table from the SQL endpoint. On the
      Properties
       view, select the
      Advanced
       tab.
  2. Click the value field for constraints.
    The
    Constraints
     dialog box appears.
  3. Click
    New
     to open the Expression editor.
  4. Configure the constraint logic and use expression functions and columns as parameters.
  5. Click
    Validate
    .
  6. Click
    OK
