如果您询问 SQL*Plus 命令（show create table table_name似乎不是 SQL 语句），您可以使用desc命令
SQL> desc emp
Name Null? Type
----------------------------------------- -------- ----------------------------
EMPNO NOT NULL NUMBER(4)
ENAME VARCHAR2(10)
JOB VARCHAR2(9)
MGR NUMBER(4)
HIREDATE DATE
SAL NUMBER(7,2)
COMM NUMBER(7,2)
DEPTNO NUMBER(2)
如果你真的想要一条 SQL 语句，你可以使用dbms_metadata包
1 select dbms_metadata.get_ddl( 'TABLE', 'EMP', 'SCOTT' )
2* from dual
SQL> /
DBMS_METADATA.GET_DDL('TABLE','EMP','SCOTT')
--------------------------------------------------------------------------------
CREATE TABLE "SCOTT"."EMP"

根据您使用的工具，您可能需要先运行set long 10000，这会告诉 SQL*Plus 显示所选 LOB 的前 10,000 个字节。如果您的 DDL 较长，请设置较大的值。

如果您使用的是 PL/SQL Developer；右键单击表，选择视图，在视图窗口的右下方单击“查看 SQL”按钮。

请注意，表名区分大小写，您需要以大写形式传入表名。

DDL对我有用，更简单的是你需要写DDL (SCHEMA_OWNER).(TABLE_NAME)......例如ddl HR.LOCATIONS;......HR是模式并且LOCATION是表名......确保你在这里用大写写SCHEMA名字和表NAME输出将是

"STREET_ADDRESS" VARCHAR2(40),
"POSTAL_CODE" VARCHAR2(12),
"CITY" VARCHAR2(30) CONSTRAINT "LOC_CITY_NN" NOT NULL ENABLE,

"COUNTRY_ID" CHAR(2),
