查看建表语句：

select dbms_metadata.get_ddl('TABLE','TEST_SQL','TEST') from dual;

DBMS_METADATA.GET_DDL('TABLE','TEST_SQL','TEST')
--------------------------------------------------------------------------------
CREATE TABLE "TEST"."TEST_SQL"
( "ID" VARCHAR2(500) NOT NULL ENABLE,

可以看到查询结果是显示不完整的，此时如果想要查看全部内容，需要重新调整一下字段大小。

set long xxx（数值）

例如：set long 9999

接下来就可以查看到完整的建表语句：

SQL > set long 9999
select dbms_metadata.get_ddl('TABLE','TEST_SQL','TEST') from dual;

DBMS_METADATA.GET_DDL('TABLE','TEST_SQL','TEST')
--------------------------------------------------------------------------------

CREATE TABLE "TEST"."TEST_SQL"
( "ID" VARCHAR2(500) NOT NULL ENABLE,
"NAME" LONG,
"COLUMNA" VARCHAR2(2000),
"COLUMNB" VARCHAR2(20),
"COLUMNC" VARCHAR2(6),
"COLUMND" VARCHAR2(20),
"COLUMNE" VARCHAR2(200),
"COLUMNF" VARCHAR2(200),
"COLUMNG" VARCHAR2(1) DEFAULT 1,
"COLUMNH" VARCHAR2(20),
