Yes it's very possible, everything is possible in coding!

You just need arrays instead of macros which are constants and you cannot change constants.

Here is a relative example: (note: i haven't used mysql in a while, syntax can be different in latest version)

PHP код:

#define MAX_MESSAGES 10
#define MAX_MESSAGE_SIZE 144
new myMessages[MAX_MESSAGES][MAX_MESSAGE_SIZE];
public OnGameModeInit() {
    new mySQL = mysql_connect(...);
    mysql_tquery(mySQL, 
        "SELECT * FROM your_table LIMIT "#MAX_MESSAGS"", 
        "OnMessagesLoad", "\1"
    );
}
forward OnMessageLoad();
public OnMessageLoad() {
    for (new i = 0; i < cache_get_row_count(); i++) {
        cache_get_field_content(i, "field_name", myMessages[i], MAX_MESSAGE_SIZE);
    }
    // now you have all messages saved in your array "myMessages"
    // to access them, say print a message at index 5
    printf("message 5: %s", myMessage[5]);
}
