Iam trying to refresh the materialized view by using   DBMS MVIEW REFRESH  v materialized foo tbl     But it s throwing invalid sql statement    Then I have created a stored procedure like this   CREATE OR REPLACE  PROCEDURE MAT VIEW FOO TBL  IS BEGIN    DBMS MVIEW REFRESH  v materialized foo tbl   END MAT VIEW FOO TBL IS    This procedure has been created successfully but when i am calling this procedure with   MAT VIEW FOO TBL    it s throwing an error again   Kindly suggest a solution for this issue   Thanks  Srinivas

If you re working with SQL Developer  you have to put the dbms view in lowercase   The rest compiled fine for me although I haven t called the procedure from code yet   CREATE OR REPLACE PROCEDURE  MAT VIEW FOO TBL  AS  BEGIN   dbms mview refresh  v materialized foo tbl    END

Best option is to use the     argument for the method   This way DBMS MVIEW will choose the best way to refresh  so it ll do the fastest refresh it can for you    and won t fail if you try something like method   f  when you actually need a complete refresh   -   from  the SQL Plus prompt   EXEC DBMS MVIEW REFRESH  my schema my mview   method   gt

try this    DBMS SNAPSHOT REFRESH   v materialized foo tbl   f       first parameter is name of mat view and second defines type of refresh  f denotes fast refresh  but keep this thing in mind it will override any any other refresh timing options

When we have to use inbuilt procedures or packages we have to use  EXECUTE  command then it will work   EX   EXECUTE exec DBMS MVIEW REFRESH  v materialized foo tbl

a bit late to the game  but I found a way to make the original syntax in this question work  I m on Oracle 11g      first switch to schema of your MV     EXECUTE DBMS MVIEW REFRESH LIST  gt  MV MY VIEW      alternatively you can add some options   EXECUTE DBMS MVIEW REFRESH LIST  gt  MV MY VIEW  PARALLELISM  gt 4     this actually works for me  and adding parallelism option sped my execution about 2 5 times    More info here  How to Refresh a Materialized View in Parallel
