通常将Oracle存储过程编译为本地编译方式的测试记录.
测试用表:
?
1 2 3 4 5 6 7 SQL> create table t1(rid number); Table created SQL> create table t_n(rid number); Table created测试用的存储过程:
?
1 2 3 4 5 6 7 8 9 10 11 12 13 create or replace procedure pro_xcl(p1 varchar2) is begin dbms_output.put_line(p1); insert into t1 select rownum as rr from dual connect by rownum < 1000000; commit; exception when others then dbms_output.put_line(sqlcode||' : '||substr(sqlerrm,200)); end;测试:
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 SQL> set serveroutput on SQL> set timing on --查看存储过程当前编译方式 SQL> select plsql_code_type from all_plsql_object_settings where name='PRO_XCL'; PLSQL_CODE_TYPE -------------------------------------------------------------------------------- INTERPRETED Executed in 0.14 seconds SQL> exec pro_xcl('11g INTERPRETED'); 11g INTERPRETED PL/SQL procedure successfully completed Executed in 4.68 seconds更改下，pro_xcl，将t1换成t_n表。
测试本地编译方式出来的存储过程运行速度.
