java一个接口调用太多sql,JAVA调用sqlserver存储过程的实现（返回多个结果集的实现）...
Sqlserver使用的为2008R2
1、存储过程
USE [YZC_BI]
GO
/****** Object: StoredProcedure [dbo].[CalYlfwColumnData] Script Date: 08/20/2014 09:24:27 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:
-- Create date:
-- Description:
-- =============================================
ALTER PROCEDURE [dbo].[CalYlfwColumnData] @xmbm varchar(max),@tjsp varchar(max),@startdate varchar(10),@enddate varchar(10)
-- Add the parameters for the stored procedure here
-- = ,
-- =
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
select * from table
END
slqserver存储过程里面返回的结果集只需要在最后select，然后在java中获取即可，Oracle则需要另外处理。
2、java程序实现，首先导入对应的驱动包
①返回结果集为一个的情况
package me.hua.main.database;
import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class CallProcedure {
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String url = "jdbc:sqlserver://127.0.0.1:1433;DatabaseName=dbname";
Connection conn = null;
CallableStatement cs = null;// PreparedStatement,Statement
ResultSet rs;
public void getConn() {
try {
Class.forName(driver);
conn = DriverManager.getConnection(url, "sa", "sasa");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
public void callProc() {
try {
cs = conn.prepareCall("{call CalYlfwColumnData(?,?,?,?)}");
cs.setString(1, "123");
cs.setString(2,"123");
cs.setString(3,"201301");
cs.setString(4,"201312");
ResultSet rs = cs.executeQuery();
while(rs != null && rs.next()){
System.out.println("ID:"+rs.getString(1));
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
if (cs != null)
cs.close();
if (conn != null)
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) {
CallProcedure dao = new CallProcedure();
dao.getConn();
dao.callProc();
}
}
②返回结果集为多个的情况
着重看红色部分
/**
* 返回结果为多个结果集的存储过程调用
* @param procName
* @param param
* @return 返回多个结果集
*/
public ArrayList> callProc(String procName,Map param) {
getConn();
ArrayList> resultList = new ArrayList>();
try {
//拼接调用存储过程的sql
String sql = "{call ";
sql += procName;
sql += "(";
for(int i = 0; i < param.size();i++){
if(i != 0){
sql += ",?";
}else{
sql += "?";
}
}
sql += ")}";
cs = conn.prepareCall(sql);
//设置参数
for(int i = 1; i <= param.size();i++){
cs.setString(i, param.get(i+""));
}
boolean flag = cs.execute();
ResultSet result;
if("CalYlfwColumnData".equals(procName)){
//医疗收费柱状图
int resultCount = 0;
do{
result = cs.getResultSet();
if(result != null){
if("1".equals(param.get("6"))){//初始化方法
if( resultCount == 0 || resultCount == 1){
List dataList = new ArrayList();
while(result.next()){
ChartDateModel chartDataModel = new ChartDateModel();
chartDataModel.setId(result.getString(1));
chartDataModel.setName(result.getString(2));
chartDataModel.setLineValue(result.getString(3));//调价后总收入
chartDataModel.setValue(result.getString(4));//调价前总收入
chartDataModel.setValue1(result.getString(5));//药品加成
dataList.add(chartDataModel);
}
resultList.add(dataList);
}else if(resultCount == 2){
List dataList = new ArrayList();
while(result.next()){
ChartDateModel chartDataModel = new ChartDateModel();
chartDataModel.setXmbm(result.getString(1));
chartDataModel.setXmmc(result.getString(2));
chartDataModel.setJjdw(result.getString(3));//
chartDataModel.setSfjg(result.getString(4)==null?0f:Float.parseFloat(result.getString(4)));//
chartDataModel.setYwl(result.getString(5)==null?0f:Float.parseFloat(result.getString(5)));//
chartDataModel.setTjsp(result.getString(6)==null?0f:Float.parseFloat(result.getString(6)));
chartDataModel.setTjzs(result.getString(7)==null?0f:Float.parseFloat(result.getString(7)));
chartDataModel.setXmlb(result.getString(8));
dataList.add(chartDataModel);
}
resultList.add(dataList);
}
}else if("2".equals(param.get("6"))){
if( resultCount == 0){
List dataList = new ArrayList();
while(result.next()){
ChartDateModel chartDataModel = new ChartDateModel();
chartDataModel.setXmbm(result.getString(1));
chartDataModel.setXmmc(result.getString(2));
chartDataModel.setJjdw(result.getString(3));//
chartDataModel.setSfjg(result.getString(4)==null?0f:Float.parseFloat(result.getString(4)));//
chartDataModel.setYwl(result.getString(5)==null?0f:Float.parseFloat(result.getString(5)));//
chartDataModel.setTjsp(result.getString(6)==null?0f:Float.parseFloat(result.getString(6)));
chartDataModel.setTjzs(result.getString(7)==null?0f:Float.parseFloat(result.getString(7)));
chartDataModel.setXmlb(result.getString(8));
dataList.add(chartDataModel);
}
resultList.add(dataList);
}
}
resultCount++;
}
cs.getMoreResults();
continue;
}while(result != null);
System.out.println("count:"+resultCount);
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
if (cs != null)
cs.close();
if (conn != null)
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
return resultList;
}
