查询数据库里所有表名和字段名的语句
SQL 查询所有表名：
SELECT NAME FROM SYSOBJECTS WHERE TYPE=‘U‘
SELECT * FROM INFORMATION_SCHEMA.TABLES
查询表的所有字段名：
SELECT NAME FROM SYSCOLUMNS WHERE ID=OBJECT_ID(‘ 表名‘ )
SELECT * FROM INFORMATION_SCHEMA.TABLES
SELECT * FROM INFORMATION_SCHEMA.VIEWS
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
ORACLE 查看所有表名:
SELECT TABLE_NAME FROM USER_TABLES
ACCESS 查看所有表名：
SELECT NAME FROM MSYSOBJECTS WHERE TYPE=1 AND FLAGS=0
MSYSOBJECTS 是系统对象，默认情况是隐藏的。通过工具、选项、视图、显示、系统对象可以使之显示出来。
