Oracle 数据库执行批处理脚本

1、执行批量赋值脚本

/*** DML ***/
declare
v_sql varchar2(500) := '';
v_condition VARCHAR2(200) := ' ';
v_relationyear number :=0;
v_relationmonth number :=0;
v_relationweek number :=0;
v_relationdays number :=0;
v_relationhours number :=0;
v_relationminute number :=0;
v_relationseconds number :=0;
v_relationworkorder number :=0;
v_relationwarehose number :=0;
v_relationworkgroup number :=0;
begin
v_sql := 'select
t.relationyear,
t.relationmonth,
t.relationweek,
t.relationdays,
t.relationhours,
t.relationminute,
t.relationseconds,
t.relationworkorder,
t.relationwarehose,
t.relationworkgroup
from materialbatch t where 1=1' || v_condition;
execute immediate v_sql
into
v_relationyear,
v_relationmonth,
v_relationweek,
v_relationdays,
v_relationhours,
v_relationminute,
v_relationseconds,
v_relationworkorder,
v_relationwarehose,
v_relationworkgroup;
DBMS_OUTPUT.put_line('v_relationyear--' || v_relationyear ||',---v_relationworkgroup---'||v_relationworkgroup);
commit;
end;

2、执行删除表和创建表脚本

/*** DDL ***/ 
begin 
EXECUTE IMMEDIATE 'drop table table_001'; 
EXECUTE IMMEDIATE 'create table table_001(name varchar2(8),address varchar2(200))'; 
end;

3、执行插入脚本

/*** DML ***/ 
declare 
v_1 varchar2(8); 
v_2 varchar2(10); 
str varchar2(50); 
begin 
v_1:='张三'; 
v_2:='中国'; 
str := 'INSERT INTO table_001(name ,address) VALUES (:1, :2)'; 
EXECUTE IMMEDIATE str USING v_1, v_2; 
commit; 
end;

4、返回结果集过程

CREATE OR REPLACE package pkg_test as 
/* 定义ref cursor类型 
不加return类型，为弱类型，允许动态sql查询， 
否则为强类型，无法使用动态sql查询; 
*/ 
type myrctype is ref cursor; 

--函数申明 
function get(intID number) return myrctype; 
end pkg_test; 
/ 

CREATE OR REPLACE package body pkg_test as 
--函数体 
function get(intID number) return myrctype is 
rc myrctype; --定义ref cursor变量 
sqlstr varchar2(500); 
begin 
if intID=0 then 
--静态测试，直接用select语句直接返回结果 
open rc for select id,name,sex,address,postcode,birthday from 
student; 
else 
--动态sql赋值，用:w_id来申明该变量从外部获得 
sqlstr := 'select id,name,sex,address,postcode,birthday from student 
where id=:w_id'; 
--动态测试，用sqlstr字符串返回结果，用using关键词传递参数 
open rc for sqlstr using intid; 
end if; 

return rc; 
end get; 

end pkg_test; 
/

5、返回单行结果

declare  
    str varchar2(500);  
    c_1 varchar2(10);  
    r_1 test%rowtype;  
begin  
    c_1:='张三';  
    str:='select * from test where name=:c WHERE ROWNUM=1';  
    execute immediate str into r_1 using c_1;  
    DBMS_OUTPUT.PUT_LINE(R_1.NAME||R_1.ADDRESS);  
end ;
