sql執行計劃跑偏，手動固化執行計劃

1-根據sql語句查找sql_id and plan_hash_value

select sql_id,child_number,hash_value,plan_hash_value,SQL_PLAN_BASELINE,last_load_time,executions,cpu_time,executions from v$sql where sql_text like 'select ADR.ACCOUNT,SUM(ADR.SEND_NUM) %'

 

2-手動固化執行計劃

declare

u int;

begin

u:=dbms_spm.LOAD_PLANS_FROM_CURSOR_CACHE(SQL_ID=>'62j207kcy1dtm',PLAN_HASH_VALUE=>'4249289261');

DBMS_OUTPUT.put_line('導入完成!');

end;
