kavy 原文 oracle返回多结果集
Oracle存储过程：
create or replace procedure P_Sel_TopCount2(in_top in number,
out_count out number,
cur_out_1 out sys_refcursor,
cur_out_2 out sys_refcursor) is
--查询指定记录条数的数据，并返回总共记录数，返回多个数据集
begin
SELECT COUNT(*) into out_count FROM userinfo;
open cur_out_1 for
SELECT * FROM userinfo where id < in_top;
open cur_out_2 for
SELECT * FROM userinfo where id < 5;
end P_Sel_TopCount2;Java调用
简单地写一个Java Class.
public void openCursor(){
Connection conn = null;
ResultSet rs = null;
CallableStatement stmt = null;
String sql = “{? = call PKG_HOTLINE.getHotline()}“;
try{
conn = getConnection();
stmt = conn.prepareCall(sql);
stmt.registerOutParameter(,OracleTypes.CURSOR);
stmt.registerOutParameter(,OracleTypes.CURSOR);
stmt.execute();
rs = ((OracleCallableStatement)stmt).getCursor();
while(rs.next()){
String country = rs.getString();
String pno = rs.getString();
System.out.println(“country:“+country+“|pno:”+pno);
}
rs = ((OracleCallableStatement)stmt).getCursor();
while(rs.next()){
String country = rs.getString();
String pno = rs.getString();
System.out.println(“country:“+country+“|pno:”+pno);
}
}
catch(Exception ex)
{
ex.printStackTrace();
}
finally
{
closeConnection(conn,rs,stmt);
}
}
