UpdateData
public BackndReturnObject UpdateMyLatestData(string tableName, Param param)
public BackndReturnObject UpdateMyData(string tableName, string inDate, Param param)
public BackndReturnObject UpdateOtherData(string tableName, string inDate, string owner_inDate, Param param)
Parameters
Value | Type | Description |
---|---|---|
tableName | string | Name of table to be updated |
inDate | string | inDate value of the row to be updated |
owner_inDate | string | inDate of the user who owns the row |
param | Param | Information to be updated |
Description
UpdateMyLatestData method modifies a piece of my data that has been registered most recently in the table.
UpdateMyData method modifies a piece of my data in the table identical to inDate.
UpdateOtherData method modifies a piece of my data in the table identical to inDate and owner_inDate. (If public, the data of others can also be modified.)
- The data can be modified regardless of schema definition status.
- You can only modify your own public/private data.
- You can modify the public data of others.
- You cannot modify the private data of others.
- 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
When only some of the columns in the row exist in param, only those columns are modified.
- Columns not in the param will not be deleted.
When there are columns that do not exist in a row of the param, they will undergo the following process:
- For a table whose schema is not defined, if a column that does not exist in the row is updated, a new column is added.
- For a table whose schema is defined, if a column whose schema is not declared is updated, an error occurs.
Reserved column
When saving, eight fields, including partition, gamer_id, inDate, updatedAt, sender, receiver, reservationDate, and owner_inDate, are used by the server.
When these columns are included in the param, an error occurs.
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 |
In the case of old version tables' rows without the owner_inDate, an owner_inDate column is added when the rows are updated by using the corresponding method.
Example
Synchronous
Param param = new Param();
param.Add("gold", 100);
param.Add("level", 2);
// Modify my data that has been registered most recently in the table
Backnd.PlayerTable.UpdateMyLatestData("tableName", param);
// Modify my data in the table that is identical to inDate
Backnd.PlayerTable.UpdateMyData("tableName", "2023-10-25:11:34:24.124Z", param);
// Modify data in the table identical to inDate and owner_inDate (data of others can also be modified)
Backnd.PlayerTable.UpdateOtherData("tableName", "2023-10-25:11:34:24.124Z", "2023-10-22:09:14:35.616Z", param);
Asynchronous
Param param = new Param();
param.Add("gold", 100);
param.Add("level", 2);
// Modify my data that has been registered most recently in the table
Backnd.PlayerTable.UpdateMyLatestData("tableName", param, (callback) =>
{
// Post-process
});
// Modify data in the table that is identical to inDate
Backnd.PlayerTable.UpdateMyData("tableName", "2023-10-25:11:34:24.124Z", param, (callback) =>
{
// Post-process
