如何在 SQL Developer 中显示查询的完整结果？

Question

我想查看用于在 SQL Developer 中创建表DOCTORS的查询

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

然后它只显示查询的一部分。

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。 您能否详细说明如何显示完整结果？

-- Drop tables if they already exist
BEGIN
    EXECUTE IMMEDIATE 'DROP TABLE works_in';
EXCEPTION
    WHEN OTHERS THEN
        IF SQLCODE != -942 THEN
            RAISE;
        END IF;
END;
/

BEGIN
    EXECUTE IMMEDIATE 'DROP TABLE depends';
EXCEPTION
    WHEN OTHERS THEN
        IF SQLCODE != -942 THEN
            RAISE;
        END IF;
END;
/

BEGIN
    EXECUTE IMMEDIATE 'DROP TABLE wards';
EXCEPTION
    WHEN OTHERS THEN
        IF SQLCODE != -942 THEN
            RAISE;
        END IF;
END;

BEGIN
    EXECUTE IMMEDIATE 'DROP TABLE doctors';
EXCEPTION
    WHEN OTHERS THEN
        IF SQLCODE != -942 THEN
            RAISE;
        END IF;
END;

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

试着把

set long 1000000 longc 100000 pages 10000

在 select dbms_metadata...之前。它告诉 sqldev（和 sqlplus/sqlcl 也是）获取 1MB 的数据，直到 10000 行之后才放置标题
