2	Update	by Primary key
3	Query	* by Primary key * by Search rules ( like or updatetime or latest item / order by ? (time ...) ) * All ( order by time )
4	Clean	*by Primary Key *by Search rules ( like or updatetime or latest item / order by ? (time ...) ) *All items of Table
5	Create Table	*AutoIndex *UniqueKey

Protocol Params in JSON Format

{			
  "Protocol":"MQTT",
   "MQTT":{
       "QoS":2,
       "Retain":0
   }						
}

Data Extend Information and SQL Structure for Handler to Manager

SQL Params structure. This stuucture is designed for Hanlder pass its log behavior.

typedef struct SQLParams
{
  int   nVer;              // Version of SQL Param	: 1
  int   nAction;          // 0: Insert or Update, 1: Delete, 2: Query
  char *pszPrimaryKey;    // NULL => Auto Index
  char **pszOutDataPoint; // Pass this point to save result of query
  char *pszGeneralInfo;   // 
  int  *pnStatus;              // status code
  void *pExtend1;
  void *pExtend2;				
}SQL_PARAMS, SQL_Params;    

Data extened Information Structure. Handler can add more information while sending data to WISE Manager.

typedef struct DataExInfo
{	
  int   nVer;            // Data Ex Info version: 1					
  void *pSqlParams;      // address of SQL parameters structure
  void *pExtend1;        // Reserved
  void *pExtend2;        // Reserved
}DATAEX_INFO, DataEx_Info;
