 ### Pseudocolumns
 
+**Pseudocolumn:** A pseudo-column behaves like a table column but is not actually stored in the table. You can select from pseudo-columns, but you cannot insert, update, or delete their values. A pseudo-column is also similar to a function without arguments. This section describes these pseudo-columns:

 **TBNAME**
 The TBNAME pseudocolumn in a supertable contains the names of subtables within the supertable.

 ### 伪列

 **TBNAME**
 `TBNAME` 可以视为超级表中一个特殊的标签，代表子表的表名。
