查看Oracle当前用户下的信息（用户，表视图，索引，表空间，同义词，存储过程函数，约束条件）
where segment_name=upper('&index_name'); 4、序列号 查看序列号，last_number是当前值 SQL>select * from user_sequences; 5、视图 查看视图的名称 SQL>select view_name from user_views; 查看创建视图的select语句 SQL>set view_name,text_length from user_views; SQL>set long 2000; 说明：可以根据视图的text_length值设定set long 的大小 SQL>select text from user_views where view_name=upper('&view_name'); 6、同义词 查看同义词的名称 SQL>select * from user_synonyms;SELECT * FROM ALL_SYSNONYMS; 7、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; 8、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');
