Oracle调用存储过程执行CRUD的小DEMO

-------修改（表名，主键ID,要修改的列）

create or replace procedure pro_code_edit(p_tbname in varchar2,p_ct_id in varchar2,p_codename in varchar2) as

   p_str varchar2(400);

begin

  p_str := 'update '||p_tbname||' set codename = '''||p_codeName||''' where ct_id = '''||p_ct_id||'''';

  execute immediate p_str;

end;

--查询所有记录,直接返回游标 在调用处做下一步处理

create or replace procedure pro_code_queryall(p_tbname in varchar2,p_list out sys_refcursor ) as
begin
    open p_list for 'select * from '||p_tbname||'';
end;
--查询单条记录（表名，主键，要查询的字段）

create or replace procedure pro_code_queryone(p_tbname in varchar2,p_ct_id in varchar2,
                 p_code out varchar2,p_codename out varchar2,p_fathercode out varchar2) as
     v_code varchar2(40);
     v_codename varchar2(40);
     v_fathercode varchar2(40);
     v_str varchar2(400);
begin
     v_str:='select code,codename,fathercode  from '||p_tbname||' where ct_id = :p' ;
     execute immediate v_str into v_code,v_codename,v_fathercode  using p_ct_id ;
     p_code:=v_code;
     p_codename:=v_codename;
    p_fathercode:=v_fathercode;
end;
--删除记录（表名，主键值）

--这里的主键名称是通过命令查询出来的

create or replace procedure pro_code_remove(p_tbname in varchar2,p_ct_id in varchar2) as
    v_str varchar2(400);
    v_con_name varchar2(40);
    v_pid varchar2(40):=trim(p_ct_id);
    v_pk_column_name varchar2(40);
    v_tbname varchar2(400):=upper(trim(p_tbname));
begin
    select constraint_name into v_con_name from all_constraints where owner=upper('daily') and constraint_type = 'P'
    and table_name=v_tbname;
    select column_name into v_pk_column_name from all_cons_columns where owner=upper('daily') and table_name=v_tbname
    and constraint_name = v_con_name;
   v_str :='delete  from doorkind where '||v_pk_column_name||' = :p ';
   execute immediate v_str using v_pid;
end;

--保存记录（在这里由于数据设计的特殊之处，主键是按照规则自动生成的）

create or replace procedure pro_code_save(p_tbname in varchar2,p_codename in varchar2) as
     v_codetype varchar2(100);
     p_id varchar2(400);
     p_str varchar2(400);
     v_len number(10);
     v_left varchar2(100);
     v_right varchar2(100);
begin
     v_codetype:=p_tbname;
     p_str:='select max(ct_id) from '||v_codetype;
     execute immediate p_str into p_id;
     dbms_output.put_line(p_id);
     select codetype,codelength into v_codetype,v_len from codenavigation where upper(codetype) = upper(v_codetype);


     if p_id is not null then
        v_left := regexp_substr(p_id,'[A-Za-z]+',1,1);
       v_right := regexp_substr(p_id,'[0-9]+',1,1);
       v_right := lpad(v_right + 1,v_len,'0');
     else
       v_left:=v_codetype;
       v_right := lpad(1,v_len,'0');
     end if;
       p_id:=v_left||v_right;
       dbms_output.put_line(p_id);


     p_str:='insert into '||v_codetype||'  '||' values('''||p_id||''','''||v_right||''','''||p_codeName||''','''||v_left||''')';
     
     execute immediate p_str;
     dbms_output.put_line(p_str);
end;
