Re: Don't display the results?

>From the SQL*Plus Reference Manual:

"set AUTOT[RACE] {ON|OFF|TRACE[ONLY]} [EXP[LAIN]] [STAT[ISTICS]] Displays a report on the execution of successful SQL DML statements (SELECT, INSERT, UPDATE or DELETE). The report can include execution statistics and the query execution path.

OFF does not display a trace report. ON displays a trace report. TRACEONLY displays a trace report, but does not print query data, if any. EXPLAIN shows the query execution path by performing an EXPLAIN PLAN. STATISTICS displays SQL statement statistics. Information about EXPLAIN PLAN is documented in the Oracle8i SQL Reference manual.

Using ON or TRACEONLY with no explicit options defaults to EXPLAIN STATISTICS.

The TRACEONLY option may be useful to suppress the query data of large queries. If STATISTICS is specified, SQL*Plus still fetches the query data from the server, however, the data is not displayed.

The AUTOTRACE report is printed after the statement has successfully completed.

Information about Execution Plans and the statistics is documented in the Oracle8i Tuning manual.

When SQL*Plus produces a STATISTICS report, a second connection to the database is automatically created. This connection is closed when the STATISTICS option is set to OFF, or you log out of SQL*Plus.

The formatting of your AUTOTRACE report may vary depending on the version of the server to which you are connected and the configuration of the server.

AUTOTRACE is not available when FIPS flagging is enabled. "
