Warning

Using an invalid handle will crash your server! Get a valid handle by using db_query. But it's protected against NULL references.


Example Usage:

// Callback
public OnPlayerCommandText(playerid, cmdtext[])
{
	// If "cmdtext" equals "/EchoWoetJoinList"
	if(!strcmp(cmdtext, "/EchoWoetJoinList", true, 17))
	{
		// Declare "db_result" and "info"
		new DBResult:db_result, info[2][30];
 
		// Select the join list of the player "Woet"
		db_result = db_query(db_handle, "SELECT * FROM `join_log` WHERE `name`='Woet'");
 
		// Do these
		do
		{
			// Store the data of "ip" into "info[0]"
			db_get_field_assoc(db_result, "ip", info[0], sizeof info[]);
 
			// Store the data of "time" into "info[1]"
			db_get_field_assoc(db_result, "time", info[1], sizeof info[]);
 
			// Print into the console
			printf("Print join list: Name: Woet IP: %s Date: %s", info[0], info[1]);
		}
 
		// While next row has been fetched
		while(db_next_row(db_result));
