jdbc 调用存返回值的存储过程 及存储过程带 like 参数

create or replace procedure Proc_Educationhealth(regionCode in varchar2,invyear in varchar2 ,outsql out varchar2,cur_out_1 out sys_refcursor) is
v_sql varchar2(2000);
begin
v_sql := 'select count(COUNTY)  总县数, sum(TOTALPOPULATIONS)  年末总人口,sum(VILLAGEPOPULATIONS)  乡村人口 ,sum(TOTALVILLAGES)  行政村个数,
sum(NURSERYVILLAGES)  有幼儿园的行政村数,sum(HOSPITALVILLAGES)  有卫生室的行政村数,sum(LASTHOSPITALBEDS)  上年卫生机构床位数,
sum(LASTWELFAREBEDS)  社会福利机构床位数  from INV_COUNTY where COUNTY like ''%'|| regionCode || '%'' and  INVYEAR =' || invyear;
outsql :=v_sql;
open cur_out_1 for

v_sql;

end Proc_Educationhealth;
