GetMyData

public BackendReturnObject GetMyData(string tableName);
public BackendReturnObject GetMyData(string tableName, int limit);
public BackendReturnObject GetMyData(string tableName, int limit, string firstKey);
public BackendReturnObject GetMyData(string tableName, string[] select);
public BackendReturnObject GetMyData(string tableName, string[] select, int limit);
public BackendReturnObject GetMyData(string tableName, string[] select, int limit, string firstKey);
public BackendReturnObject GetMyData(string tableName, string inDate);
public BackendReturnObject GetMyData(string tableName, string inDate, string[] select);

Parameters

Value	Type	Description	Default
tableName	string	Name of table to look up	-
limit	int	(Optional) Number of game information rows to load. Minimum 1, maximum 100.	10
inDate	string	inDate value of the row to look up	-
owner_inDate	string	inDate of the user who owns the row	-
select	string[]	(Optional) Columns to include among existing columns in the row	Includes all columns
firstKey	string	(Optional) Starting point of data lookup	Data that was inserted last

Description

Among the values saved in the table, all values equal to the number of limits are loaded.

• The data can be looked up regardless of schema definition status.
• Both public and private data can be looked up.
• The throughput of the data is the same regardless of whether the select clause is used.

Example

Synchronous

 }
 // When loading is successful but data does not exist
 if(bro.IsSuccess() && bro.FlattenRows().Count <= 0) 
 {
    Debug.Log("The data does not exist");
 }
 // When more than one piece of data is loaded
 if(bro.FlattenRows().Count > 0)

    string inDate = bro.FlattenRows()[0]["inDate"].ToString();
    int level = int.Parse(bro.FlattenRows()[0]["level"].ToString());
 }
 // Load up to one row added by myself from tableName

ReturnCase

Success cases

When the lookup is successful
statusCode : 200

returnValue : refer to GetReturnValuetoJSON

When the lookup succeeds but there is no row with the relevant inDate
statusCode : 200

returnValue : {"serverTime":"2021-03-23T07:07:01.235Z","rows":[],"firstKey":null}

Error cases

When the inDate is string.Empty upon executing GetMyData using inDate
statusCode : 400
errorCode : ClientException

When Get is attempted on a non-existent table
statusCode : 404
errorCode : NotFoundException

When an attempt is made to load to an inactive tableName
statusCode : 412
errorCode : PreconditionFailed

GetReturnValuetoJSON (Values within rows all differ depending on the data.)
