# 如何查询表的存储方式？
答：可通过表定义函数pg_get_tabledef()查询，row表示行存。具体查询方式如下所示：
```
--查询test_1表的存储方式。
gaussdb=# SELECT * FROM pg_get_tabledef('test_1');
                             pg_get_tabledef                              
--------------------------------------------------------------------------
 SET search_path = public;                                               +
 CREATE TABLE test_1 (                                                   +
     a integer                                                           +
 )                                                                       +
 WITH (orientation=row, compression=no, storage_type=USTORE, segment=off)+
 DISTRIBUTE BY HASH(a)                                                   +
 TO GROUP group_version1;
(1 row)
```
