使用SQL Server sp_send_dbmail从java发送电子邮件

Question

我正在尝试使用SQL Server sp_send_dbmail从java发送电子邮件

在SQLServer本身中，以下命令可以很好地发送HTML电子邮件。[即，我已按照要求正确设置发送电子邮件的所有内容 Microsoft's instructions ]

EXEC msdb.dbo.sp_send_dbmail
    @profile_name = 'example profile',
    @recipients = 'me@example.com',
    @body = @tableHTML,
    @body_format = 'HTML' ,
    @subject = 'Email from SQL Server';

但是，当尝试使用以下代码从java发送时

public static synchronized int sendEmail(String profileName,String recipients,String body, String body_format,String subject) {
        final String sendEmailStr = "{execute msdb.dbo.sp_send_dbmail (?,?,?,?,?,?)}";
        dbConn  = DBConnection.getInstance();
        Connection conn = dbConn.getConnection();
        CallableStatement stmt = null;
        int result = RESULT_FAILED;
        try {
            stmt = conn.prepareCall(sendEmailStr);
            stmt.setString("profile_name", profileName);
            stmt.setString("recipients", recipients);
            stmt.setString("body", body);
            stmt.setString("body_format", body_format);
            stmt.setString("subject", subject);

            stmt.registerOutParameter(6, java.sql.Types.INTEGER);
            stmt.execute();
            result = stmt.getInt(6);
        } catch(SQLException e) {
            System.out.println(e);
            Log.getInstance().write("Exception on sendEmail " + e.toString());
        } finally {
            try {
                stmt.close();
                dbConn.returnConnection(conn);
            } catch(SQLException e) {
                System.out.println(e);
                Log.getInstance().write("Exception on sendEmail " + e.toString());
            }
        }
        return result;
    }

我得到以下异常com.microsoft.sqlserver.jdbc.SQLServerException: com.microsoft.sqlserver.jdbc.SQLServerException: Parameter profile_name was not defined for stored procedure

我做错了什么

请将查询字符串更改为使用call，如下所示：

 final String sendEmailStr "{ call msdb.dbo.sp_send_dbmail (?,?,?,?,?,?) }";

要使用当前数据库中的存储过程，请在当前数据库中执行此操作，通过本地过程包装MSDB调用：

  Use [MyDatabase]; 
     CREATE PROCEDURE [MyDB].[SEND_EMAIL_DB] 
       @profile_name2 varchar(max), 
       @recipients2 varchar(max), 
       @body2 varchar(max), 
       @body_format2 varchar(max), 
       @subject2 varchar(max), 
       @p_result int OUTPUT 
     AS 
       BEGIN  
          exec msdb.dbo.sp_send_dbmail  @profile_name=@profile_name2,
                   @recipients=@recipients2,@body=@body2,
                   @body_format=@body_format2,@subject=@subject2 
       END
