Parameters

Value	Type	Description	Default
playerDataTransactionRead	PlayerDataTransactionRead	Class where transaction tasks are stored	-

PlayerDataTransactionRead

These are classes that add data-loading commands.

Load one piece of latest data from all data
public PlayerDataTransactionRead AddGetAllLatestData(string tableName);

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

// Data most recently inserted into the table
playerDataTransactionRead.AddGetAllLatestData("SCORE");

Load my data
public PlayerDataTransactionRead AddGetMyLatestData(string tableName);
public PlayerDataTransactionRead AddGetMyData(string tableName, string inDate);

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

// Data most recently inserted into the table by myself
playerDataTransactionRead.AddGetMyLatestData("SCORE");

// Load data with inDate value of "2023-09-14T12:43:54.451Z" from the data I registered 
playerDataTransactionRead.AddGetMyData("USER_DATA", "2023-09-14T12:43:54.451Z");

Load another person's data
public PlayerDataTransactionRead AddGetOtherLatestData(string tableName, string owner_inDate);
public PlayerDataTransactionRead AddGetOtherData(string tableName, string inDate, string owner_inDate);

// Obtain the user's owner_inDate by searching the user name
var userBro = Backend.Social.GetUserInfoByNickName("nickName");
string otherOwnerIndate = userBro.GetReturnValuetoJSON()["row"]["inDate"].ToString();

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

// Load the most recent data registered by the user with a matching owner_inDate in the table
playerDataTransactionRead.AddGetOtherLatestData("SCORE", otherOwnerIndate);

// Load data with inDate value of "2023-09-14T12:43:54.451Z" from the data registered by the user with a matching owner_inDate in the table
playerDataTransactionRead.AddGetOtherData("USER_DATA", "2023-09-14T12:43:54.451Z", otherOwnerIndate);

Description

The transaction read commands in transactionList are requested to the server.

• If there is no data that matches the given conditions, an error occurs instead of rows[].
• If the same row is loaded by a command in playerDataTransactionRead, an error occurs.
• Up to 10 tasks can be grouped into 1 unit.
• When at least one request in the task list has an error, all requests will fail.
• For all requests to be handled as success, all requests must succeed.

Example

Synchronous

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

playerDataTransactionRead.AddGetAllLatestData("PUBLIC_DATA");

playerDataTransactionRead.AddGetMyLatestData("ACHIVE_DATA");
playerDataTransactionRead.AddGetMyData("USER_DATA", "2023-09-17T14:16:32.341Z");

var userBro = Backend.Social.GetUserInfoByNickName("nickName");
string otherOwnerIndate = userBro.GetReturnValuetoJSON()["row"]["inDate"].ToString();

playerDataTransactionRead.AddGetOtherLatestData("SCORE", otherOwnerIndate);
playerDataTransactionRead.AddGetOtherData("USER_DATA", "2023-09-19T16:21:12.542Z", otherOwnerIndate);

Backend.PlayerData.TransactionRead(playerDataTransactionRead);

Asynchronous

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

playerDataTransactionRead.AddGetAllLatestData("PUBLIC_DATA");

playerDataTransactionRead.AddGetMyLatestData("ACHIVE_DATA");
playerDataTransactionRead.AddGetMyData("USER_DATA", "2023-09-17T14:16:32.341Z");

var userBro = Backend.Social.GetUserInfoByNickName("nickName");
string otherOwnerIndate = userBro.GetReturnValuetoJSON()["row"]["inDate"].ToString();

playerDataTransactionRead.AddGetOtherLatestData("SCORE", otherOwnerIndate);
playerDataTransactionRead.AddGetOtherData("USER_DATA", "2023-09-19T16:21:12.542Z", otherOwnerIndate);

Backend.PlayerData.TransactionRead(playerDataTransactionRead, callback => {

});

SendQueue

PlayerDataTransactionRead playerDataTransactionRead = new PlayerDataTransactionRead();

playerDataTransactionRead.AddGetAllLatestData("PUBLIC_DATA");

playerDataTransactionRead.AddGetMyLatestData("ACHIVE_DATA");
playerDataTransactionRead.AddGetMyData("USER_DATA", "2023-09-17T14:16:32.341Z");

var userBro = Backend.Social.GetUserInfoByNickName("nickName");
string otherOwnerIndate = userBro.GetReturnValuetoJSON()["row"]["inDate"].ToString();

playerDataTransactionRead.AddGetOtherLatestData("SCORE", otherOwnerIndate);
playerDataTransactionRead.AddGetOtherData("USER_DATA", "2023-09-19T16:21:12.542Z", otherOwnerIndate);

Sendqueue.Enqueue(Backend.PlayerData.TransactionRead, playerDataTransactionRead, callback => {
    
});

ReturnCase

Success cases

When all requests are successful
statusCode : 200

returnValue : refer to GetReturnValuetoJSON

Error cases

When an error occurs in at least 1 task while performing a transaction task
An error corresponding to the error situation will be returned.
For the error that occurs during 'Get,' refer to the relevant developer documentation.

When 2 or more tasks are performed to the same row
statusCode : 400
errorCode : ValidationException

When there are over 10 tasks in transactionList, or when there are no tasks
statusCode : 400
errorCode : TransactionSizeError

When there is a request that failed to find data because the conditions were not met
statusCode : 404
errorCode : NotFoundException
