六、同义词
查看同义词的名称
SQL>select * from user_synonyms;
七、约束条件
查看某表的约束条件
SQL>select constraint_name, constraint_type,search_condition, r_constraint_name
from user_constraints where table_name = upper('&table_name');
SQL>select c.constraint_name,c.constraint_type,cc.column_name
from user_constraints c,user_cons_columns cc
where c.owner = upper('&table_owner') and c.table_name = upper('&table_name')
and c.owner = cc.owner and c.constraint_name = cc.constraint_name
order by cc.position;
八、存储函数和过程
查看函数和过程的状态
SQL>select object_name,status from user_objects where object_type='FUNCTION';
SQL>select object_name,status from user_objects where object_type='PROCEDURE';
查看函数和过程的源代码
SQL>select text from all_source where owner=user and name=upper('&plsql_name');
九、触发器
查看触发器
set long 50000;
set heading off;
set pagesize 2000;
select
'create or replace trigger "' ||
trigger_name || '"' || chr(10)||
decode( substr( trigger_type, 1, 1 ),
'A', 'AFTER', 'B', 'BEFORE', 'I', 'INSTEAD OF' ) ||
chr(10) ||
triggering_event || chr(10) ||
'ON "' || table_owner || '"."' ||
table_name || '"' || chr(10) ||
decode( instr( trigger_type, 'EACH ROW' ), 0, null,
'FOR EACH ROW' ) || chr(10) ,
trigger_body
from user_triggers;
