 oracle：

导出所有表名+字段名：

select t.TABLE_NAME 表名 ,t.COLUMN_ID 序号 ,t.COLUMN_NAME 字段名 ,t.DATA_TYPE 类型 ,t. DATA_LENGTH 长度 ,t.NULLABLE 是否为空
from user_tab_columns t

其他：

SELECT OBJECT_NAME(sc.object_id)TABLE_NAME ,* FROM sys.index_columns SC

SELECT OBJECT_NAME(I.object_id),* FROM sys.indexes I
--AND sc.object_id = i.object_id
--AND sc.index_id = i.index_id
SELECT * FROM sys.columns --所有表字段
