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//useprotocoldb//dropprocedureifexistssp_protocol_Update//createproceduresp_protocol_Update(inp_ProtocolNodeUIDvarchar(64),inp_VersionUIDvarchar(64),inp_ParentProtocolNodeUIDvarchar(64),inp_IsDefaultSelectedTINYINT(1),inp_SequenceOrderINT(11),inp_NodeTypeCHAR(50),inp_NodeKeyvarchar(64),inp_NodeLabelvarchar(200),inp_ExamedBodyPartvarchar(200),inp_ScanTypeSupportedCHAR(50),inp_PatientPositionCHAR(50),inp_PrivateProtocolFilePathvarchar(1024),inp_Descriptionvarchar(1024),inp_LeftRightFlagCHAR(50),inp_AgeGroupCHAR(50),inp_FileVersionNumbervarchar(64),inp_ExampleFigurePathvarchar(1024),inp_PatientTypeIDvarchar(64),inp_ProcedureIDvarchar(64),inp_PSASIDvarchar(64),inp_ProtocolIDvarchar(64),inp_IsFavouriteTINYINT(1),inp_IsTimedTINYINT(1),inp_IsFactoryPredefineTINYINT(1),inp_IsNeedInjectionTINYINT(1),inp_IsLicensedTINYINT(1),inp_IsCardicScanTINYINT(1),inp_IsPediatricTINYINT(1),inp_CreateDateDATETIME,inp_CreateByvarchar(64),inp_UpdateDateDATETIME,inp_UpdateByvarchar(64))beginupdateprotocolnodesetVersionUID=p_VersionUID,ParentProtocolNodeUID=p_ParentProtocolNodeUID,IsDefaultSelected=p_IsDefaultSelected,SequenceOrder=p_SequenceOrder,NodeType=p_NodeType,NodeKey=p_NodeKey,NodeLabel=p_NodeLabel,ExamedBodyPart=p_ExamedBodyPart,ScanTypeSupported=p_ScanTypeSupported,PatientPosition=p_PatientPosition,PrivateProtocolFilePath=p_PrivateProtocolFilePath,Description=p_Description,LeftRightFlag=p_LeftRightFlag,AgeGroup=p_AgeGroup,FileVersionNumber=p_FileVersionNumber,ExampleFigurePath=p_ExampleFigurePath,PatientTypeID=p_PatientTypeID,ProcedureID=p_ProcedureID,PSASID=p_PSASID,ProtocolID=p_ProtocolID,IsFavourite=p_IsFavourite,IsTimed=p_IsTimed,IsFactoryPredefine=p_IsFactoryPredefine,IsNeedInjection=p_IsNeedInjection,IsLicensed=p_IsLicensed,IsCardicScan=p_IsCardicScan,IsPediatric=p_IsPediatric,CreateDate=p_CreateDate,CreateBy=p_CreateBy,UpdateDate=p_UpdateDate,UpdateBy=p_UpdateBywhereProtocolNodeUID=p_ProtocolNodeUID;end//DELIMITER;2.用EF映射存储过程在ModelView里选择FunctionImport，添加存储过程的映射方法。如XXX.Designer.cs里的

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：ThespecifiedFunctionImportisnotmappedtoastorefunctionandcannotbeexecuted.

解决办法，打开Modelview,选择对应的FunctionImport，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//[/b]

mysql>CREATEPROCEDUREsimpleproc(OUTparam1INT)[/b]

->BEGIN[/b]

->SELECTCOUNT(*)INTOparam1FROMt;[/b]

->END[/b]

->//[/b]
