plsql EXECUTE IMMEDIATE动态执行sql

select * from BANK t;

DECLARE
v_money bank.money%TYPE;
BEGIN

--简单执行sql,注意sql字符串不要带分号结束
EXECUTE IMMEDIATE \'SELECT money FROM bank WHERE id = 5\';

--带参数，参数使用using传入，按顺序的传入
EXECUTE IMMEDIATE \'SELECT money FROM bank WHERE id = :param1 or id =:param2\'
USING \'4\',\'5\';

--执行sql后，取值，using在赋值后面
EXECUTE IMMEDIATE \'SELECT money FROM bank WHERE id = :param1\'
INTO v_money
USING \'2\';

DBMS_OUTPUT.PUT_LINE( \'Column Variable: \' || v_money );

END;

 注意：

--using是用于变量参数，但变量是参与sql语句的就不ok啊
EXECUTE IMMEDIATE \'SELECT sysdate FROM dual WHERE :param\'
USING \'1=1\';
--sql 会变成下面的无效sql
SELECT sysdate FROM dual WHERE \'1=1\'
