Oracle操作錦集

查詢所有包含EQUIPMENTTYPE列名的Table

select * from user_tab_columns;

select * from user_tab_columns where column_name='EQUIPMENTTYPE';

查看Oracle最近執行的語句

select * from v$sql;

select * from v$sql where last_active_time > sysdate - 1/24/60;

爲新用戶創建所有表的同義詞：

先查詢出每句"創建同義詞的sql"，再用查詢出來的sql，去執行

select 'CREATE SYNONYM '|| table_name||' FOR '||owner||'.'||table_name||';' from dba_all_tables where owner ='EDA';

CREATE SYNONYM TABLE1 FOR EDA.TABLE1;
CREATE SYNONYM TABLE2 FOR EDA.TABLE2;
CREATE SYNONYM TABLE3 FOR EDA.TABLE3;
......
