The editor will share with you the usage of set autotrace in the database. I hope you will gain something after reading this article. Let's discuss it together.

Usage: SET AUTOT [RACE] {OFF | ON | TRACE [ONLY]} [explain] [stats]]

Description:

One of the first three parameters {OFF | ON | TRACE [ONLY]} must be selected, and only one can be selected.

The last two parameters [explain] [STAT [ISTICS]] are optional, or neither can be selected.

The meaning of TRACE [ONLY] is to show only explain and statistic, but not the result set of SQL. The following 4memes with parameters of TRACE [ONLY] are the fourth most commonly used.

As long as you bring off, the following [explain] [stats] will be invalid.

1:set autotrace on

Display: recordset + explain+statistics

2:set autotrace on explain

Display: recordset + explain

3:set autotrace on statistic

Display: recordset + statistics

4:set autotrace traceonly

Display: expain+statistics (no data is displayed)

5:set autotrace traceonly statistics

Display: statistics

6:set autotrace traceonly explain

Display: explain

7:set autotrace off

Display: only the recordset is displayed, which is the default SQL PLUS window effect
