Database Field

Field

From the drop-down list choose the required database field. This list will only contain those fields that are valid for the field type chosen above.

Field in layer table

This option is only visible if the particular database has the Table type PDB Layer Extra in the Database Table Structure. If this is the case the field drop-down list will contain appropriate field names from the LAYERS database table as well. Selecting one of those fields will cause this option to be automatically checked.

This option is required so that Impact can correctly store the data for fields in the LAYERS table. Also, so it can distinguish between a field with the same name being added to both the LAYERS and ONE_UP table, for example. When this option is checked the data is stored internally with the name LAYERS.L_FIELD rather than just L_FIELD as it would for ONE_UP columns.

Value cannot be modified (Read-only)

Switch this option on to make this field read-only.

Use this field when performing a Find

Switch this option on to allow this field to be used when searching the database from the Find Window form. See also the options on the External Tables form.
