如何在 SQL Developer 中显示查询的完整结果？

Question

我想查看用于在 SQL 开发人员

中创建 table DOCTORS 的查询

SELECT dbms_metadata.get_ddl('TABLE', 'DOCTORS')
FROM dual;

然后它只显示部分查询。

DBMS_METADATA.GET_DDL('TABLE','DOCTORS')                                        
--------------------------------------------------------------------------------

  CREATE TABLE "C##AKIRA"."DOCTORS" 
   (    "CODED" NUMBER(2,0),  
    "NAMED" VARCHA

我怀疑这是由于某些显示设置造成的。能否请您详细说明如何显示完整结果？

        IF SQLCODE != -942 THEN

        END IF;
END;

        END IF;
END;

BEGIN

-- Show the schema of a table
SELECT dbms_metadata.get_ddl('TABLE', 'DOCTORS')
FROM dual;

Answer 1

试试放

set long 1000000 longc 100000 pages 10000

在selectdbms_metadata之前.... 它告诉 sqldev（以及 sqlplus/sqlcl 也）获取 1MB 的数据并且直到 10000 行

之后才放置 headers
