execute immediate的簡單用法(oracle)

直接上示例代碼：

create or replace procedure proc_test(
--參數區域
)
is 
--變量區域
    --sql腳本
    v_sql varchar2(2000) :='';
    --記錄學生數量
    v_num number;
begin
--執行區域

    -- execute immediate用法1：立刻執行sql語句
    v_sql := 'create or replace view myview as select id,name from student';
    execute immediate v_sql;
    
    --- execute immediate用法2：立刻執行sql語句，並賦值給某個變量
    v_sql := 'select count(1) from student';
    execute immediate v_sql into v_num;
    
    -- execute immediate用法3：帶參數的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;
