make_table
Aliases: droptime (deprecated).
make_table
Converts a non-Table dataset to kind Table by clearing temporal metadata and key constraints while keeping the same data columns.
For non-Table inputs, the compiler unsets the Valid From and Valid To metadata fields, clears alignment, and drops primary and candidate keys plus associated constness. When the input is already a Table, the row type and key metadata are left unchanged. The verb takes no arguments. For execution, temporal inputs are restricted to the interactive query window before time columns are dropped, so converting a wide history does not imply scanning outside the window. Use make_event, make_interval, or make_resource when you need timestamps or packed resource state again.

Accelerable
make_table is never accelerable. A dataset that only uses accelerable verbs can be accelerated, making queries on the dataset respond faster.
Examples
make_table
Converts a temporally keyed dataset to Table by removing validity metadata so the former interval bounds remain as timestamp columns only.
make_table
Shows the no-op path where the input is already kind Table so column names and values pass through without temporal metadata changes.
