Managing type expressions

To view a list of all type expressions, Navigate to Settings > Expressions and select the Type Expressions tab.

The type expressions on the screen can be filtered or sorted by the various informational fields by clicking on the respective field. More information on grid filtering and sorting can be found here.

  • Sortable fields are Name and Domain.

  • Filterable fields are Name, Domain, and Owner.

  • The profile-type-expressions/search endpoint also allow for searching and filtering of profile-type expressions. More information on syntax can be found at API Calls for Searching and Filtering.

Adding new Type Expression

  1. Click the + Type Expression button from the top-right corner above the Type Expressions grid.

  2. Enter the Expression Name and select a Domain.

  3. Select Constraints (Data Type) for the expression: String, Numeric, Binary, Date.

  4. Set a Minimum Column Length for the data type if desired.

    • Note: Length constraints are not applied to large object types such as CLOBs and BLOBs.

  5. For example, to ensure that column-level profiling only identifies a column with the FIRST_NAME domain, if the column is a string type and has a capacity of at least 5 characters, add the type constraint shown below.

  6. When you are finished, click Save.
