How to get execution plan in a CLOB?

Question

Hello,
I want to get execution plans of a query in a CLOB format. I am trying to run following query against v$sql view. One of the columns I want is the execution plan for the query. I am getting following error. Eventually, I am going to insert this data into a log table to keep history of all SQLs and their execution plans.
How can I do that?
Thank you in advance.
SQL> SELECT sql_id,
  2         plan_hash_value,
  3         TO_CLOB (DBMS_XPLAN.display_awr (sql_id            => sql_id,
  4                                          plan_hash_value   => plan_hash_value,
  5                                          format            => '+PEEKED_BINDS'))
  6            sql_plan_clob,
  7         buffer_gets,
  8         executions
  9    FROM v$sql
10   WHERE ROWNUM < 5;
       TO_CLOB (DBMS_XPLAN.display_awr (sql_id            => sql_id,
ERROR at line 3:
ORA-00932: inconsistent datatypes: expected NUMBER got SYS.DBMS_XPLAN_TYPE_TABLE

Answer 1

try first
select *
  from table(DBMS_XPLAN.display_awr(sql_id          => sql_id,
                                    plan_hash_value => plan_hash_value,
                                    format          => '+PEEKED_BINDS'
            )to see the table returned
then try to adapt http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:68212348056 to produce fixed length rows.
look for describe_columns procedures in http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/d_sql.htm#i1025449 for column length information available in internal tables and write the rows directly to clob instead of writing to disk and loading your clob from there.
