InsertData

public BackendReturnObject InsertData(string tableName);
public BackendReturnObject InsertData(string tableName, Param param);

Parameters

Value	Type	Description
tableName	string	Name of table where the game information will be stored
param	Param	Content to be stored in the game information

Description

A row is added to the table.

• The row is bound to the user who InsertData-ed that row.
• The data can be inserted regardless of the schema definition status.
• Both public and private data can be inserted.
• When inserting schema, null or the default value is entered if the value is empty.
• For numerical data, you can safely input numbers up to 9,007,199,254,740,991(approximately 9 quadrillion).
  When your input data exceeds the limit above, place values in units and tens are rounded down to 0.
  As the number increases and place values expand, small numbers are rounded down, and large numbers are maintained up to 16 - 18 digits, based on the left.
  For long, the data is saved as shown below:
  12345678912345678 -> 12345678912345678(within the limit of 9 quadrillion, the input number is maintained)
  123456789123456789 -> 123456789123456780(exceeds the limit of 9 quadrillion, the last digit is rounded down)
  1234567891234567891 -> 1234567891234568000
  9223372036854775807 -> 9223372036854776000(the maximum value for 'long')
  When saving an integer with double to save a larger piece of data, the number is displayed as shown below:
  12345678912345678912 -> 12345678912345678000(the 'double' larger than the maximum value of 'long')
  123456789123456789123.0 -> 123456789123456800000
  1234567891234567891234.0 -> 123456789123456800000000
  1.23456789123457E+29 -> 123456789123457000000000000000
  In the case of receiving the number from the client(C#), it may be changed to an exponent format.
  12345678912345678000 -> 1.23456789123457E+19

Reserved column

When saving, eight fields, including partition, gamer_id, inDate, updatedAt, sender, receiver, reservationDate, and owner_inDate, are used by the server.
If this column is included in the param, the value in the param is ignored and the value used by the server is stored.

Value	Description	Whether the value is displayed in BACKND Console
partition	Value used by the server to classify a table.	X
gamer_id	Gamer ID of the row owner.	O
inDate	inDate of the row.(Key value.)	O
updatedAt	Time the table was last modified.	O
sender	Value used internally for BACKND function(e.g., mail)	X
receiver	Value used internally for BACKND function(e.g., mail)	X
reservationDate	Value used internally for BACKND function(e.g., mail)	X
owner_inDate	User inDate of the row owner.	O

For schema tables

The following precautions apply when using schema tables:

• Entering data that does not fit the data type will result in an error.
• When the data type is set to 'string,' '10' cannot be added as data.
• When the data type is set to 'int,' 'float,' or 'double,' '10' cannot be added as data.
• When the data type is set to 'int,' entering '3.14' as data will convert it to '3.' (Decimal point is discarded.)
• When the data type is set to 'DateTime,' you can only add data that matches that type. (If 'DateTime' is set to HH:mm:ss, the data can only be entered in the format of '15:21:31,' and data cannot be added in the format of '2024-01-23T15:21:31.311Z' or '2024-01-23 15:21:31.'
• All data types cannot be added/modified as null like param.Add("item", null). (The error 'bad {data} dataType, invalid {data} dataType' will occur.)
• If null is allowed and the data does not exist in the param during data insertion, the data is created without the column.
• If null is not allowed and the data does not exist in the param, the default value is inserted automatically. However, in case of 'list' or 'map,' the data must be included during the data insertion.
• In the case of 'DateTime,' if null is not allowed and the default value is ON, the current time is configured based on UTC. (If the time in Korea is 11:35, the time is set to 02:35.) If the default value is OFF and data is inserted without including the column, an error occurs.

Example

param

Param lunch = new Param();
lunch.Add("how much", 332);
lunch.Add("when", "yesterday");
lunch.Add("what", "eat chocolate");

Dictionary<string, int> dic = new Dictionary<string, int>
{
    { "dic1", 1 },
    { "dic4", 2 },
    { "dic2", 4 }
};

Dictionary<string, string> dic2 = new Dictionary<string, string>
{
    { "mm", "j" },
    { "nn", "n" },
    { "dd", "2" }
};

String[] list = { "a", "b" };
int[] list2 = { 400, 500, 600 };

Param param = new Param();
param.Add("name", "cheolsu");
param.Add("score", 99);
param.Add("lunch", lunch);
param.Add("dic_num", dic);
param.Add("dic_string", dic2);
param.Add("list_string", list);
param.Add("list_num", list2);
