[Java教程]Java调用SQL Server存储过程

1、调用普通存储过程
(1)创建存储过程
CREATE Procedure [dbo].[GetContactListByName]  /*根据联系人姓名获取联系人信息*/
@Name nvarchar(50)
As
begin
    select Contact.Id,Contact.Name,Phone,Email,QQ,GroupName from Contact,ContactGroup
 where Contact.GroupId=ContactGroup.Id and Name like [email protected]+'%'  order by Contact.Id desc
end
(2)Java代码
final String DRIVER_CLASS = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
final String DATABASE_URL = "jdbc:sqlserver://127.0.0.1:1433;DatabaseName=AddressList";
final String DATABASE_USRE = "sa";
final String DATABASE_PASSWORD = "1234";
try {
    Class.forName(DRIVER_CLASS);
    Connection connection=DriverManager.getConnection(DATABASE_URL,DATABASE_USRE,DATABASE_PASSWORD);
    CallableStatement callableStatement=connection.prepareCall("{call GetContactListByName(?)}");
    callableStatement.setString(1, name);
    ResultSet resultSet=callableStatement.executeQuery();
    while(resultSet.next()){
        int id=resultSet.getInt(1);
        String string=resultSet.getString(2);
        System.out.println(id+","+string);
    }
} catch (Exception e) {
    // TODO: handle exception
    e.printStackTrace();
}
注意:如果存储过程无参数,则不需要写括号,如
CallableStatement callableStatement=connection.prepareCall("{call GetAllContactGroup}");
        
2、调用包含返回值及输出参数的存储过程
(1)创建存储过程
USE [AddressList]
GO
CREATE PROCEDURE [dbo].[GetGroupById]  /*根据分组编号获取分组信息*/
 @GroupName nvarchar(50) OUTPUT,   /*输出参数*/
 @Memo nvarchar(200) OUTPUT,      /*输出参数*/
 @id int
AS
BEGIN
 select @GroupName=GroupName,@Memo=Memo from ContactGroup where [email protected]
 if @@Error<>0
  RETURN -1   /*返回值*/
 else
  RETURN 0   /*返回值*/
END
(2)Java代码
    CallableStatement callableStatement=connection.prepareCall("{?=call GetGroupById(?,?,?)}");
    //返回值
    callableStatement.registerOutParameter(1, Types.INTEGER);
    //输出参数
    callableStatement.registerOutParameter(2, Types.VARCHAR);
    //输出参数
    callableStatement.registerOutParameter(3, Types.VARCHAR);
    //输入参数
    callableStatement.setInt(4, 2);
    callableStatement.execute();
    //获得返回值
    int returnValue=callableStatement.getInt(1);
    //获得输出参数
    String groupName=callableStatement.getString(2);
    //获得输出参数
    String memo=callableStatement.getString(3);
    System.out.println(returnValue);
    System.out.println(groupName);
    System.out.println(memo);
} catch (Exception e) {
    // TODO: handle exception
    e.printStackTrace();
}
3、调用包含输入输出参数的存储过程。
(1)创建存储过程
USE [AddressList]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[test]
 @GroupName nvarchar(50) output
AS
BEGIN
 select @GroupName=GroupName from ContactGroup where GroupName like [email protected]+'%'
END
(2)Java代码
CallableStatement callableStatement=connection.prepareCall("{call test(?)}");
callableStatement.setString(1, name);
callableStatement.registerOutParameter(1, Types.VARCHAR);
callableStatement.execute();
String string=callableStatement.getString(1);
System.out.println(string);
