## excerpt: Handle data from DB.

# ramdb_db_fnc_handler

## Description

Handles data received from the database and routes it to the appropriate function. This function is a critical component of the callback system, receiving data from database operations and directing it to the specified function, either locally or to a remote client.

## Syntax

[_uniqueID, _function, _call, _data, _netId] call ramdb_db_fnc_handler

## Parameters

Parameter | Type | Description | Default
--- | --- | --- | ---
`_uniqueID` | String | Unique identifier for the data chunk | ""
`_function` | String | Name of function to receive the data | ""
`_call` | Boolean | Whether to call the function directly (true) or spawn (false) | false
`_data` | Array, String, Number, or Boolean | The data retrieved from the database | []
`_netId` | String | (Optional) NetID of the player to receive the data | nil

## Return Value

None. The data is passed to the specified function for processing.

## Examples

### Process data locally:

["0123456789", "ramdb_db_fnc_test", false, ["Hello World!"]] call ramdb_db_fnc_handler;

### Send data to a specific client:

["0123456789", "ramdb_db_fnc_test", false, ["Hello World!"], netId player] remoteExecCall ["ramdb_db_fnc_handler", 2, false];

### Process data with direct call (synchronous):

["0123456789", "ramdb_db_fnc_processInventory", true, [["weapon1", 30], ["item2", 5]]] call ramdb_db_fnc_handler;

## Notes

- The function validates that both the function name and data are valid before proceeding
- When a netId is provided, the data is sent to that specific client using remoteExec
- The `_call` parameter determines whether the function is called directly (synchronous) or spawned (asynchronous)
- This function is typically called by the scheduler or other core components rather than directly by user code
- Each handler call is logged, which is useful for debugging data flow
