Select Input -- Guidelines

Select Queries. Create a select query to select cases and fields from your original data for linkage purposes. You can include calculations which change old values or add new values. You can also add extra information by joining to a reference table. Your original table should include a record identifier field. If your table does not have a record identifier field then add one before importing. In any case, confirm that the field does not include duplicate values. Rename this field as UniqueID in your query.
