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
