僅通過PLSQL打印所有列值

Question

我有以下可打印記錄參數的plsql腳本。 有沒有辦法打印只是通過country_record的所有列值。 我的意思是，我不想寫所有列名狀country_record.country_id

DECLARE 
     country_record countries%ROWTYPE; 
     countryid  countries.country_id%TYPE; 
    BEGIN 
     countryid := &countryid; 

     SELECT * 
     INTO country_record 
     FROM countries 
     WHERE country_id = countryid; 

     DBMS_OUTPUT.put_line ('id: ' || country_record.country_id); 
    END; 

Answer 1

如果打印這一切你想要的，你可以嘗試一下這個。使用SQL*Plus

VARIABLE MYCUR SYSREFCURSOR; 

DECLARE 
     country_record countries%ROWTYPE; 
     countryid  countries.country_id%TYPE; 
     plsql_cursor SYS_REFCURSOR; 
    BEGIN 
     countryid := &countryid; 

     OPEN :MYCUR for 
     SELECT * 
     FROM countries 
     WHERE country_id = countryid; 

    END; 
/

    print mycur;
