# `SQL Statements` Execution Detail

------------------------------------------------------------------------------
After clicking on an SQL statement, the `Execution Detail` page is displayed. This page provides output similar to the `EXPLAIN ANALYZE` command. Here, we will concentrate on the `time` values in the `execution info` column, as both `time` and `loops` are standard information available for all operators listed in this column. Additional details will be examined as we analyze each operator within the SQL statement.

The `time` value in the `execution info` column indicates the total duration the operator has been executing. Some operators consist of multiple sub-operators, and their total execution time includes the combined execution time of each sub-operator. For instance, consider the example `IndexLoopUP_11 (time: 2.26ms)`, which is formed by the sub-operators `IndexRangeScan_8(Build) (time: 1.39ms)` and `Selection_10(Probe) (time: 699.8µs)`. Since sub-operators may execute concurrently, the aggregate of their execution times can be longer than the parent operator's recorded `time`.

The `time` value in the `execution info` column can be used to determine the actual execution time of an operator, and `actRows` provides the actual number of rows scanned by the operator. This information is invaluable for optimizing SQL statements.
