Parameters​

ValueTypeDescriptionDefalut
tableNamestringName of table to look up-
whereWhereThe where clause to search-
limitint(Optional) Number of game information rows to load. Minimum 1, maximum 100.10
selectstring[](Optional) Columns to include among existing columns in the rowIncludes all columns
firstKeystring(Optional) Starting point of data lookupData that was inserted last
sortOrderTableSortOrder(Optional) TableSortOrder.DESC(descending order) or TableSortOrder.ASC(ascending order)TableSortOrder.DESC(descending order)

Description​

The data stored in the table is looked up.

  • The data can be looked up regardless of schema definition status.
  • Both public and private data can be looked up.
  • In the case of a private table, you can look up only your own data.
  • The throughput of the data is the same regardless of whether the select clause is used.

Look up all data without conditions​

To search all data without conditions, declare 'where,' which is passed as a parameter value, as new Where().

Look up only the data of a specific user​

To only look up the public table of a specific user, you can declare a where condition as shown below:

Where where = new Where();
where.Equal("owner_inDate", "user's gamerInDate");
  • In the case of owner_inDate, as the search is performed using the user's key value, the search process may be accelerated if this condition is added to the conditional statement.
  • gamerIndate can be checked with the GetUserInfoByNickName method or via the user information returned from methods such as friend or guild member lookup.

Example 1​

Search all data without conditions

Synchronous​

// Look up all data without conditions
var bro = Backend.GameData.Get("tableName", new Where(), 10);
if(bro.IsSuccess() == false)
{
// Request handled as failure
Debug.Log(bro);
return;
}
if(bro.GetReturnValuetoJSON()["rows"].Count <= 0)
{
// Even if the request succeeds, there might not be a piece of data that meets the where condition
// Therefore, you must confirm that the corresponding piece of data exists
// In the case of the new Where() condition example above, the Count may be 0 or less if there is no row in the table.
Debug.Log(bro);
return;
}

// Checks the inDate value of all rows for the searched data
for(int i=0; i<bro.Rows().Count; ++i)
{
var inDate = bro.Rows()[i]["inDate"]["S"].ToString();
Debug.Log(inDate);
}

Asynchronous​

// Look up all data without conditions
Backend.GameData.Get("tableName", new Where(), 10, bro =>
{
if(bro.IsSuccess() == false)
{
// Request handled as failure
Debug.Log(bro);
return;
}
if(bro.GetReturnValuetoJSON()["rows"].Count <= 0)
{
// Even if the request succeeds, there might not be a piece of data that meets the where condition
// Therefore, you must confirm that the corresponding piece of data exists
// In the case of the new Where() condition example above, the Count may be 0 or less if there is no row in the table.
Debug.Log(bro);
return;
}
// Checks the inDate value of all rows for the searched data
for(int i = 0; i < bro.Rows().Count; ++i)
{
var inDate = bro.Rows()[i]["inDate"]["S"].ToString();
Debug.Log(inDate);
}
});

SendQueue​

// Look up all data without conditions
SendQueue.Enqueue(Backend.GameData.Get, "tableName", new Where(), 10, bro =>
{
if(bro.IsSuccess() == false)
{
// Request handled as failure
Debug.Log(bro);

if(bro.GetReturnValuetoJSON()["rows"].Count <= 0)
{
// Even if the request succeeds, there might not be a piece of data that meets the where condition
// Therefore, you must confirm that the corresponding piece of data exists
// In the case of the new Where() condition example above, the Count may be 0 or less if there is no row in the table.
Debug.Log(bro);
return;
}
// Checks the inDate value of all rows for the searched data
for(int i = 0; i < bro.Rows().Count; ++i)
{
var inDate = bro.Rows()[i]["inDate"]["S"].ToString();
Debug.Log(inDate);
}
});

Example 2​

Look up only the deck and score columns in a specific user's data

Synchronous​

// When returning through the use of select[], set to print only deck and score
string[] select = { "deck", "score" };
// Where clause for searching data of a specific user
Where where = new Where();
where.Equal("owner_inDate", "user's inDate value(user key value)");

// Look up only the deck and score columns in a specific user's data
var bro = Backend.GameData.Get("tableName", where, select, 10);
if(bro.IsSuccess() == false)
{
// Request handled as failure
Debug.Log(bro);
return;
}
if(bro.GetReturnValuetoJSON()["rows"].Count <= 0)
{
// Even if the request succeeds, there might not be a piece of data that meets the where condition
// Therefore, you must confirm that the corresponding piece of data exists
Debug.Log(bro);
return;
}
// Checks the score of the first row from the searched conditions
int score = (int)bro.Rows()[0]["score"]["N"];

Asynchronous​

// When returning through the use of select[], set to print only deck and score
string[] select = { "deck", "score" };
// Where clause for searching data of a specific user
Where where = new Where();
where.Equal("owner_inDate", "user's inDate value(user key value)");

// Therefore, you must confirm that the corresponding piece of data exists
