文档解释 ORA-54037: table must have at least 1 column that is not virtual Cause: An attempt was made to create a table with
ORA-54037: table must have at least 1 column that is not virtual
Cause: An attempt was made to create a table with only virtual columns.
Action: Include at least 1 column that is not virtual in the table being created.
**ORA-54037: table must have at least 1 column that is not virtual**
错误说明:
ORA-54037 错误是表必须至少具有1个非虚拟列抛出的。当您创建表时,在数据库中定义一个新的表时,每一列都有一个与之关联的数据类型。虚拟列由于找不到对应的基础列,而不能有效地创建虚拟列。
ORA-54037 错误基本上发生在运行以下语句时:
“`
CREATE TABLE T1 ( C1 AS (SELECT ‘X’) );
“`
或
“`
CREATE TABLE T1 ( C1 VIRTUAL (SELECT ‘X’) );
“`
解决方法:
要解决此错误,只要添加一个非虚拟列到表中,即可满足这一要求。例如:
“`
CREATE TABLE T1 ( C1 AS (SELECT ‘X’), C2 VARCHAR2(10) );
“`
或
“`
CREATE TABLE T1 ( C1 VIRTUAL (SELECT ‘X’), C2 VARCHAR2(10) );
“`
这样,T1 表就包含了一个以上的非虚拟列,可以避免ORA-54037错误,成功地创建表。
