java調用存儲過程參數
import java.sql.*;
public class ProcereTest
{
public static void main(String args[]) throws Exception
{
//載入驅動
DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver());
//獲得連接
Connection conn=DriverManager.getConnection("jdbc:odbc:mydata","sa","");
//創建存儲過程的對象
CallableStatement c=conn.prepareCall("{call getsum(?,?)}");
//給存儲過程的第一個參數設置值
c.setInt(1,100);
//注冊存儲過程的第二個參數
c.registerOutParameter(2,java.sql.Types.INTEGER);
//執行存儲過程
c.execute();
//得到存儲過程的輸出參數值
System.out.println (c.getInt(2));
conn.close();
}
}
❷ Java中，怎樣調用帶輸出參數的存儲過程(轉)
1、創建帶輸出參數的存儲過程 如： 在查詢分析器中執行declare @mg nvarchar(100) exec proc_CSCO_SalesFctByStore 100,200,'name',@mg output print @mg 在Java中調用import java.sql.*; public class Test{ public static void main(String args[]) throws Exception {//載入驅動DriverManager.registerDriver(new sun.jdbc.odbc.JdbcOdbcDriver()); //獲得連接 Connection conn = DriverManager.getConnection("jdbc:odbc:mydata", "sa",""); //創建存儲過程的對象 CallableStatement c = conn.prepareCall("{call proc_CSCO_SalesFctByStore(?,?,?,?)}"); //給存儲過程的第一個參數設置值 c.setInt(1, 100); //給存儲過程的第一個參數設置值 c.setInt(2, 10000); //給存儲過程的第一個參數設置值 c.setString(3, user); //注冊存儲過程的第四個參數 c.registerOutParameter(4, java.sql.Types.VARCHAR); //執行存儲過程 c.execute(); //得到存儲過程的輸出參數值
❸ java代碼怎麼調用存儲過程
方法如下：importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.ResultSet;importjava.sql.SQLException;importjava.sql.Statement;/***LoadJDBCDriver*最基本的方法通過JDBC連接資料庫*@authorJacob**/publicclassLoadByPrimary{publicstaticvoidmain(String[]args)throwsClassNotFoundException{Stringdriver="oracle.jdbc.OracleDriver";Connectioncn=null;/***Class.forName手動載入一個類到方法區，Driver類中包含自動注冊驅動的靜態代碼塊*會自動在DriverManager中注冊驅動*/Class.forName(driver);Stringurl="jdbc:oracle:thin:@localhost:1521:ORACLE";//1521代表埠號，默認的Stringuser="用戶名";Stringpwd="密碼";try{/**Connection是介面，返回值是一個引用對象，是Oracle驅動提供實現類ojdbc7.jar*使用JDBCAPI介面，實際上是驅動實現類*/cn=DriverManager.getConnection(url,user,pwd);Statementstmt=cn.createStatement();Stringsql="SELECT*FROMstu_empWHEREdeptno=10";ResultSetrs=stmt.executeQuery(sql);while(rs.next()){System.out.println(rs.getInt("empno")+""+rs.getString("ename")+""+rs.getString("job"));}rs.close();stmt.close();}catch(SQLExceptione){e.printStackTrace();}finally{try{if(cn!=null){cn.close();}}catch(SQLExceptione2){e2.printStackTrace();}}}}這是通過preparedstatement實現更新數據，這里我把連接資料庫的方法進行了封裝，每次直接調用了。publicstaticvoidmain(String[]args){PreparedStatementDemopsd=newPreparedStatementDemo();psd.updateSalary("JACOB",3000);psd.selectSalary("JACOB");}publicvoipdateSalary(Stringename,doublesal){Stringsql="Updatestu_empsetsal=?Whereename=?";Connectioncn=null;PreparedStatementps=null;try{cn=DBPUtil.getConnection();ps=cn.prepareStatement(sql);ps.setDouble(1,sal);ps.setString(2,ename);intnum=ps.executeUpdate();System.out.println("提示：總共有"+num+"條數據已經更新！");}catch(SQLExceptione){e.printStackTrace();}finally{DBUtil.stmtClose(ps);DBUtil.connClose(cn);}}publicvoidselectSalary(Stringname){Stringsql="Select*Fromstu_empWhereename=?";Connectioncn=null;PreparedStatementps=null;ResultSetrs=null;try{cn=DBPUtil.getConnection();ps=cn.prepareStatement(sql);ps.setString(1,name);rs=ps.executeQuery();while(rs.next()){System.out.println(rs.getString("ename")+"的工資是："+rs.getInt("sal"));}}catch(SQLExceptione){e.printStackTrace();}finally{DBUtil.stmtClose(ps);DBUtil.rsClose(rs);DBUtil.connClose(cn);}}}
❹ java調用的存儲過程，能否傳入游標參數
java調用的存儲過程，不能傳入游標參數，但是存儲過程調用的內部存儲過程，可以存入游標參數。未完待續
❺ JAVA調用存儲過程，Oracle自定義類型作參數怎麼寫法
1. 存儲過程以及類型定義如下：
--The array in oracle
CREATE OR REPLACE TYPE idArray AS TABLE OF VARCHAR2(20);
--package header
CREATE OR REPLACE PACKAGE Lib_Package AS
PROCEDURE Book_Check_Procere(ids IN idArray, exist OUT NUMBER);
END Lib_Package;
--package body
CREATE OR REPLACE PACKAGE BODY Lib_Package AS
PROCEDURE Book_Check_Procere( ids IN idArray, exist OUT NUMBER) AS v_Index BINARY_INTEGER; BEGIN v_Index:= ids.FIRST; LOOP SELECT COUNT(*) INTO exist FROM Lib_Duplicate WHERE status='Lent' AND book_id=ids(v_Index); EXIT WHEN v_Index=ids.LAST OR exist>0; v_Index:= ids.NEXT(v_Index); END LOOP;END Book_Check_Procere;
END Lib_Package;
2.在Java中調用上面的存儲過程
(1) 在Oracle中定義數組類型idArray (2) 在java構造數組並轉換成Oracle中定義的數組類型，調用存儲過程
/** * 當要刪除圖書時，檢查是否仍然有圖書復本處於借出狀態 */ public boolean checkBookStatus(String[] bookIds) throws DataAccessException {
boolean flag = false; Connection conn = null; OracleCallableStatement cstmt = null; ArrayDescriptor desc = null; ARRAY bookIdArray = null; int count = 0; String sql = "{call LIB_PACKAGE.Book_Check_Procere(?,?)}";
DbDriverManager dbManager = DbDriverManager.getInstance(); conn = dbManager.getConnection(Constants.DATABASE);
try { cstmt = (OracleCallableStatement) conn.prepareCall(sql);
//定義oracle中的數組類型 desc = ArrayDescriptor.createDescriptor("IDARRAY", conn); bookIdArray = new ARRAY(desc, conn, bookIds);
cstmt.setObject(1, bookIdArray, oracle.jdbc.OracleTypes.ARRAY); cstmt.registerOutParameter(2, Types.INTEGER); cstmt.execute(); count = cstmt.getInt(2);
log.info(this.getClass() + ".checkBookStatus: count = " + count);
DbOperHelp.closeStatement(this.getClass(), cstmt); DbOperHelp.closeConnection(this.getClass(), conn); } catch (SQLException e) {
log.error(this.getClass() + ".checkBookStatus-->SQLException: " + e.getMessage()); DbOperHelp.closeStatement(this.getClass(), cstmt); DbOperHelp.closeConnection(this.getClass(), conn); throw new DataAccessException( "When check the books, there is a SQLException: " + e.getMessage(), e.getCause()); }
if (count > 0) {
flag = true; }
return flag; }
❻ 如何在java中調用存儲過程
使用 JDBC 驅動程序調用不帶參數的存儲過程時，必須使用 call SQL 轉義序列，
ResultSetrs=stmt.executeQuery("{calldbo.ProcereName}");
調用帶參數的存儲過程時，必須結合SQLServerConnection類的prepareCall方法使用callSQL轉義序列
CallableStatementcstmt=con.prepareCall("{calldbo.ProcereName(?,?)}");
cstmt.setInt(1,java.sql.Types.INTEGER);
cstmt.registerOutParameter(2,java.sql.Types.VARCHAR);
cstmt.execute();
System.out.println("MANAGERID:"+cstmt.getInt(1));
System.out.println("MANAGERNAME:"+cstmt.getInt(2));
❼ java裡面怎麼調用存儲過程
最近做一個自動發郵件的schele，由於取數據的sql太長，直接分割很麻煩，就想到調用PL/SQL，網上查了資料做了練習，在此做下小結。
1、只有輸入參數而沒有返回結果的存儲過程。
sql：
1 create or replace procere prc_1(deptno in number,dname in varchar2,loc in varchar2)
2 is
3 begin
4 insert into dept values(deptno,dname,loc);
5 end prc_1;
java：
1 static void test1(){
2 Connection conn=null;
3 CallableStatement csmt=null;
4 try {
5 conn=JDBCUtils.getConnection();
6 conn.setAutoCommit(false);
7 csmt=conn.prepareCall("call prc_1(?,?,?)");
8 csmt.setInt(1,80);
9 csmt.setString(2,"ioc");
10 csmt.setString(3,"fhp");
11 csmt.execute();
12 conn.commit();
13 System.out.println("success insert data");
14 } catch (SQLException e) {
15 e.printStackTrace();
16 }
17 }
2、有輸入參數且有一個返回值的存儲過程。
sql：
1 create or replace procere prc_2(p_deptno in number,p_loc out varchar2) is
2 begin
3 select loc into p_loc from dept where deptno=p_deptno;
4 end prc_2;
java：
1 static void test2(){
2 Connection conn=null;
3 CallableStatement csmt=null;
4 try {
5 conn=JDBCUtils.getConnection();
6 conn.setAutoCommit(false);
7 csmt=conn.prepareCall("call prc_2(?,?)");
8 csmt.setInt(1,70);
9 csmt.registerOutParameter(2,Types.VARCHAR);
10 csmt.execute();
11 conn.commit();
12 System.out.println("MIS位置："+csmt.getString(2));
13 } catch (SQLException e) {
14 e.printStackTrace();
15 }
16 }
3、返回多行記錄（游標）的存儲過程。
sql：
首先要建立一個返回遊標，以便接收返回結果。
1 create or replace package testpackage is
2 type test_cursor is ref cursor;
3 end testpackage;
4
5 create or replace procere prc_3(p_cursor out testpackage.test_cursor)is
6 begin
7 open p_cursor for
8 select * from dept order by deptno;
9 end prc_3;
java：
1 static void test3(){
2 Connection conn=null;
3 CallableStatement csmt=null;
4 ResultSet rs=null;
5 try {
6 conn=JDBCUtils.getConnection();
7 conn.setAutoCommit(false);
8 csmt=conn.prepareCall("call prc_3(?)");
9 csmt.registerOutParameter(1,oracle.jdbc.OracleTypes.CURSOR);
10 csmt.execute();
11 rs=(ResultSet) csmt.getObject(1);
12 while(rs.next()){
13 System.out.println(rs.getString("deptno")+'\t'+rs.getString("dname")+'\t'+rs.getString("loc"));
14 }
15 } catch (SQLException e) {
16 // TODO Auto-generated catch block
17 e.printStackTrace();
18 }finally{
19 JDBCUtils.free(rs, csmt, conn);
20 }
21 }
❽ Java中是如何調用存儲過程的
//存儲過程create or replace Procere countBySal(
p_sal emp.sal%type,
p_count OUT number
)as
begin
select count(*) into p_count from emp where sal >= p_sql;
end countBySal; //調用步奏import java.sql.CallableStatement; //帶哦用存儲過程所必須的語句借口
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Types;public class EmpUtil {
public static int countBySal(double sal) throws Exception{
Class.forName("oracle.jdbc.driver.OracleDriver");
String url="jdbc:oracle:thin:@localhost:1521:test";
Connection cn=DriverManager.getConnection(url, "scott", "tiger");
String sql="{call countBySal(?,?)}";//調用存儲過程的語句，call後面的就是存儲過程名和需要傳入的參數
CallableStatement cst=cn.prepareCall(sql);
cst.setDouble(1, sal);//設置in參數的值
cst.registerOutParameter(2, Types.INTEGER);//注冊out參數的類型
cst.execute();
int result = cst.getInt(2);
cst.close();
cn.close();
return result;
}
public static void main(String[] args) {
int count;
try {
count = EmpUtil.countBySal(3000);
System.out.println("工資在3000元以上的人數為："+count);
} catch (Exception e) {
e.printStackTrace();
}
}
}
