into_values()
Expand the state aggregate into a set of rows, displaying the duration of each state
Since 1.15.0
Unpack the state aggregate into a set of rows with two columns, displaying the duration of each state. By default, the
columns are named state and duration. You can rename them using the same method as renaming a table.
Samples
Section titled “Samples”Create a state aggregate from the table states_test. The time column is named time, and the state column contains
text values corresponding to different states of a system. Use into_values to display the data from the state
aggregate.
SELECT state, duration FROM into_values( (SELECT state_agg(time, state) FROM states_test));Returns:
