利用存储过程来提高数据库的更新问题

1. 创建存储过程，

DELIMITER //

use protocoldb//

drop procedure if exists sp_protocol_Update//

create procedure sp_protocol_Update
(
in p_ProtocolNodeUID                               varchar(64),                        
in p_VersionUID                                    varchar(64),                        
in p_ParentProtocolNodeUID                      varchar(64),

in p_SequenceOrder                              INT(11),
in p_NodeType                                   CHAR(50),
in p_NodeKey                                    varchar(64),
in p_NodeLabel                                  varchar(200),
in p_ExamedBodyPart                             varchar(200),
in p_ScanTypeSupported                          CHAR(50),
in p_PatientPosition                            CHAR(50),

in p_IsFavourite                                TINYINT(1),
in p_IsTimed                                    TINYINT(1),
in p_IsFactoryPredefine                         TINYINT(1),
in p_IsNeedInjection                            TINYINT(1),
in p_IsLicensed                                 TINYINT(1),
in p_IsCardicScan                               TINYINT(1),
in p_IsPediatric                                TINYINT(1),
in p_CreateDate                                 DATETIME,
in p_CreateBy                                   varchar(64),

2.用EF映射存储过程

在Model View里选择Function Import， 添加存储过程的映射方法。如XXX.Designer.cs里的

      #region Function Imports

        /// No Metadata Documentation available.
        /// </summary>

3.调用存储过程 

其中protocolDB是一个entity对象，sp_protocol_Udpate是存储过程映射过来的方法名。

 protocolDB.sp_protocol_Update(
                                temp.ProtocolNodeUID, 
                                temp.VersionUID,
                                temp.ParentProtocolNodeUID,
                                Convert.ToSByte(temp.IsDefaultSelected),
                                temp.SequenceOrder,
                                temp.NodeType,
                                temp.NodeKey,
                                temp.NodeLabel,
                                temp.ExamedBodyPart,
                                temp.ScanTypeSupported,
                                temp.PatientPosition,
                                temp.PrivateProtocolFilePath,
                                temp.Description,
                                temp.LeftRightFlag,
                                temp.AgeGroup,
                                temp.FileVersionNumber,
                                temp.ExampleFigurePath,
                                temp.PatientTypeID,
                                temp.ProcedureID,
                                temp.PSASID,
                                temp.ProtocolID,
                                Convert.ToSByte(temp.IsFavourite),
                                Convert.ToSByte(temp.IsTimed),
                                Convert.ToSByte(temp.IsFactoryPredefine),
                                Convert.ToSByte(temp.IsNeedInjection),
                                Convert.ToSByte(temp.IsLicensed),
                                Convert.ToSByte(temp.IsCardicScan),
                                Convert.ToSByte(temp.IsPediatric),
                                temp.CreateDate,
                                temp.CreateBy,
                                temp.UpdateDate, 
                                temp.UpdateBy
                        );

4. 注意事项

1）在调用存储过程方法时，有可能跑出一个异常：The specified FunctionImport is not mapped to a store function and cannot be executed.

解决办法，打开Model view, 选择对应的Function Import，然后右击delete，再次右击Add，填入方法名。

http://scottsdalewebstudio.com/blog/functionimport-is-not-mapped-to-a-store-function-error/

2）mysql的tinyint(1)数据类型在EF的存储过程参数中被映射为sbyte，但是EF中的对象却映射为bool。 因此，在调用EF的存储过程方法时，需要转换。

其中temp是个表对象，IsPediatric是映射过来的bool变量，通过Convert.ToSByte完美转换。

Convert.ToSByte(temp.IsPediatric)

3）Mysql的存储过程示例，注意delimiter关键字。

下面是一个使用OUT参数的简单的存储程序的例子。例子为，在 程序被定义的时候，用mysql客户端delimiter命令来把语句定界符从 ;变为//。这就允许用在 程序体中的;定界符被传递到服务器而不是被mysql自己来解释。
mysql> delimiter //
 
mysql> CREATE PROCEDURE simpleproc (OUT param1 INT)
    -> BEGIN
    ->   SELECT COUNT(*) INTO param1 FROM t;
    -> END
    -> //
Query OK, 0 rows affected (0.00 sec)
 
mysql> delimiter ;
