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
