SQL statement for Running Queries

User Running Queries

By using the following statements we can check running queries(active sessions) for particular user.

Syntax

SELECT a.sid, a.username,b.sql_id, b.sql_fulltext FROM V$SESSION a, V$SQL b
WHERE a.sql_id = b.sql_id and a.status = 'status' and a.username = '<db-user>';

Example

SELECT a.sid, a.username,b.sql_id, b.sql_fulltext from V$SESSION a, V$SQL b
WHERE a.sql_id = b.sql_id and a.status = 'ACTIVE' and a.username = 'TESTUSER';

All Running Queries

Syntax

SELECT a.sid, a.username,b.sql_id, b.sql_fulltext FROM V$SESSION a, V$SQL b
WHERE a.sql_id = b.sql_id and a.status = '<status>' ;

Example

SELECT a.sid, a.username,b.sql_id, b.sql_fulltext from V$SESSION a, V$SQL b
WHERE a.sql_id = b.sql_id and a.status = 'ACTIVE' ;

Example

SELECT sesion.sid,sesion.serial#, sql_text FROM v$sqltext sqltext, v$session sesion 
WHERE sesion.sql_hash_value = sqltext.hash_value 
AND sesion.sql_address = sqltext.address 
AND sesion.username is not null order by sqltext.piece

  6. TABLE PARTITION
  7. RULE
  8. PROCEDURE

  11. WINDOW
  12. DATABASE LINK
  13. LOB
  14. PACKAGE
  15. PACKAGE BODY
  16. LIBRARY
  17. RULE SET
  18. PROGRAM
  19. TYPE BODY
  20. CONTEXT
  21. XML SCHEMA
  22. TRIGGER
  23. JOB CLASS
  24. UNDEFINED
  25. DIRECTORY
  26. TABLE
  27. INDEX
  28. SYNONYM
  29. VIEW
  30. FUNCTION
  31. WINDOW GROUP
  32. INDEXTYPE
  33. CLUSTER
  34. TYPE
  35. RESOURCE PLAN
  36. EVALUATION CONTEXT
  37. JOB
SELECT created,object_name,owner FROM dba_objects 
WHERE owner = '<db-user>' 
AND object_type = '<object-name>'
AND object_name not like 'BIN%' 
AND to_date(created,'DD-MM-YY')='<creation-date>'

Example

SELECT created,object_name,owner FROM dba_objects 
WHERE owner = 'TESTUSER' 
AND object_type = 'TABLE'
AND object_name not like 'BIN%' 
AND to_date(created,'DD-MM-YY')='11-May-2010'

dba_objects table contains the following metadata.

Query:
describe dba_objects;
output
Name           Null Type          
-------------- ---- ------------- 
OWNER               VARCHAR2(30)  
OBJECT_NAME         VARCHAR2(128) 
SUBOBJECT_NAME      VARCHAR2(30)  
OBJECT_ID           NUMBER        
DATA_OBJECT_ID      NUMBER        
OBJECT_TYPE         VARCHAR2(19)  
CREATED             DATE          
LAST_DDL_TIME       DATE          
TIMESTAMP           VARCHAR2(19)  
STATUS              VARCHAR2(7)   
TEMPORARY           VARCHAR2(1)   
GENERATED           VARCHAR2(1)   
SECONDARY           VARCHAR2(1)

Public Database Link

  • Use the CREATE DATABASE LINK statement to create a database link.
  • A database link is a schema object in one database that enables you to access objects on another database.
  • The other database need not be an Oracle Database system. However, to access non-Oracle systems you must use Oracle Heterogeneous Services.
