execute immediate的简单用法(oracle)

直接上示例代码：

--参数区域
)
is 
--变量区域
    --sql脚本
    v_sql varchar2(2000) :='';
    --记录学生数量
    v_num number;
begin
--执行区域

    -- execute immediate用法1：立刻执行sql语句
    v_sql := 'create or replace view myview as select id,name from student';
    execute immediate v_sql;
    
    --- execute immediate用法2：立刻执行sql语句，并赋值给某个变量
    v_sql := 'select count(1) from student';
    execute immediate v_sql into v_num;
    
    -- execute immediate用法3：带参数的sql
    v_sql:='select * from student t where t.name=:1 and t.age=:2'; 
    execute immediate v_sql using 'ZhangSan',23;
    
end proc_test;
