TransactionWriteV2

public BackendReturnObject TransactionWriteV2(ListTransactionValue[] transactionList);
public BackendReturnObject TransactionWriteV2(List<TransactionValue> transactionList);

Parameters​

ValueTypeDescription
transactionListTransactionValue[] (Selection) Arrays transaction tasks
transactionListList<TransactionValue>(Selection) List where transaction tasks are stored

Description​

Transaction commands existing in transactionList are requested to the server.

  • Up to 10 tasks can be grouped into 1 unit.
  • In the case of TransactionValue, which uses inDate for searching, you may only use the tasks of SetUpdateV2 and SetDeleteV2, instead of SetUpdate and SetDelete.
  • 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​

List< TransactionValue >​

List<TransactionValue> transactionList = new List<TransactionValue>();

// Insert
Param param = new Param();
param.Add("name", "stat");
param.Add("level", 10);

transactionList.Add(TransactionValue.SetInsert("tableName", param));

//Modify
Where where = new Where();
where.Equal("name", "stat");

Param updateParam = new Param();
updateParam.Add("atk", 20);

transactionList.Add(TransactionValue.SetUpdate("tableName", where, updateParam));


// Delete
Where where2 = new Where();
where.Equal("name", "hero");

transactionList.Add(TransactionValue.SetDelete("tableName", where2));

//Modify/change data using your owner_inDate and rowInDate
string data_inDate = "2021-09-16T01:23:13.232Z";
transactionList.Add(TransactionValue.SetUpdateV2("tableName2", data_inDate, Backend.UserInDate, updateParam));
transactionList.Add(TransactionValue.SetDeleteV2("tableName2", data_inDate, BackendUserInDate));

Synchronous​

Backend.GameData.TransactionWriteV2(transactionList);

Asynchronous​

Backend.GameData.TransactionWriteV2(transactionList, (callback) => 
{
    // Post-process
});

SendQueue​

SendQueue.Enqueue(Backend.GameData.TransactionWriteV2, transactionList, (callback) => 
{
    // Post-process
});
