excerpt: Handles data chunks received from the database extension when data is too large to be returned in a single callback.
ramdb_db_fnc_fetch
Description
Handles data chunks received from the database extension when data is too large to be returned in a single callback. This function collects all chunks of data, reassembles them in the correct order, and then passes the complete data to the handler function.
Syntax
[_uniqueID, _function, _index, _total, _datachunk, _call, _netId] call ramdb_db_fnc_fetch
Parameters
Parameter
Type
Description
_uniqueID
String
Unique identifier for this data fetch operation
_function
String
Name of the function to call after data is assembled
_index
Number
Current chunk index (0-based)
_total
Number
Total number of chunks expected
_datachunk
String
The chunk of data being received
_call
Boolean
Whether to call the function directly (true) or spawn (false)
_netId
String
(Optional) NetID of the player to whom the data belongs
Return Value
None. When all chunks are received, the function will:
Assemble the complete data string
Parse it as a simple array
Call the specified handler function with the parsed data
Examples
This function is typically not called directly but is triggered by the extension's callback mechanism when large datasets are retrieved.
Notes
The function stores received chunks in the global array ramdb_db_fetch_array
Chunks are sorted by their index to ensure correct assembly regardless of arrival order
After successful processing, the chunks for this uniqueID are removed from the array
This function is essential for handling large datasets that exceed the callback buffer limit
