Because UltraLite short plans are textual summaries of how a query is accessed, you need to understand how the operations of either a join or a scan of a table are implemented.
For scan operations Represented with a single operand, which applies to a single table only and uses an index. The table name and index name are displayed as round brackets ( (, ) ) following the operation name.
For other operations Represented with one or more operands, which can also be plans in and of themselves. In UltraLite, these operands are comma-separated lists contained by square brackets ( [ ] ).
