Oracle 多参数查询语句

废话不多说了，直接给大家贴代码了，具体代码如下所示：

create or replace function f_get_param( 
      in_param in varchar2, 
      in_flag in varchar2) 
return varchar2 is 
result varchar2(500); 
v_leng number; 
v_left number; 
v_right number; 
v_param varchar2(200); 
v_param1 varchar2(200); 
begion 
 result := ''; 
 v_param:=in_param; 
 v_leng := length(v_param); 
 v_left := instr(v_param,in_flag); 
 if v_left > 0 then 
  v_param1 := substr(v_param,v_left,v_leng - v_left +1) 
  v_left := instr(v_param1,':') + 1; 
  v_right := indtr(v_param1,'$'); 
  result := substr(v_param1,v_left,v_right-v_left) 
 end if; 
 return(result); 
 exception 
  when others then 
  return ''; 
end f_get_param; 
//数据库赋值格式 
f_get_param(v_param,'materialtype:');//器件编码类型 
//数据库展示 
public string buildtoparams(listargs args) 
{ 
  string params = '$'; 
  if(args != null) 
  { 
    if(!string.isnotempty(args.materailtype)) 
    { 
      params = params + 'materialtypes:' + args.materailtype + '$'; 
    } 
  } 
  return params; 
} 
//oracle 数据库拓展-多选参数 
select instr(',' || '1,2,3,21' || ',',',' || '1' || ',') from dual 
select * from table_name where instr(',' || list_id || ',',',' || id || ',') > 0 
//oarcle 多条件','隔开查询  
select distinct regexp_substr('我爱你'，'[^.]+',1,rownum) xyz_name from dual 
connect by rownum <= length('我爱你') - length(replace('我爱你',',')) + 1 

以上所述是小编给大家介绍的oracle 多参数查询语句，希望对大家有所帮助
