Have you install or/and configure MySQL? It's definitely required to build API services.
If we need simplicity, we could do it with only a table (which shown below).
CREATE TABLE MERIT (
ID INT(11) PRIMARY KEY NOT NULL,
QTY INT(2) NOT NULL,
MSG VARCHAR(25) NOT NULL,
SENDER INT(8) NOT NULL,
RECEIVER INT(8) NOT NULL
);
Short demo (with MariaDB, but should be fully compatible with MySQL) :
MariaDB [test]> CREATE TABLE MERIT (
-> ID INT(11) PRIMARY KEY NOT NULL,
-> QTY INT(2) NOT NULL,
-> MSG VARCHAR(25) NOT NULL,
-> SENDER INT(8) NOT NULL,
-> RECEIVER INT(8) NOT NULL
-> );
Query OK, 0 rows affected (0.029 sec)
MariaDB [test]> DESC MERIT;
+----------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+-------------+------+-----+---------+-------+
| ID | int(11) | NO | PRI | NULL | |
| QTY | int(2) | NO | | NULL | |
| MSG | varchar(25) | NO | | NULL | |
| SENDER | int(8) | NO | | NULL | |
| RECEIVER | int(8) | NO | | NULL | |
+----------+-------------+------+-----+---------+-------+
5 rows in set (0.001 sec)
MariaDB [test]> SELECT * FROM MERIT;
Empty set (0.000 sec)
MariaDB [test]> INSERT INTO MERIT VALUES (1561085310, 2, "178336.msg51543068", 452769, 239406);
Query OK, 1 row affected (0.008 sec)
MariaDB [test]> SELECT * FROM MERIT;
+------------+-----+--------------------+--------+----------+
| ID | QTY | MSG | SENDER | RECEIVER |
+------------+-----+--------------------+--------+----------+
| 1561085310 | 2 | 178336.msg51543068 | 452769 | 239406 |
+------------+-----+--------------------+--------+----------+
1 row in set (0.000 sec)
P.S. I learn SQL a bit, but i've no idea about MySQL security or performance.
It's not required to build the API service + the script CryptoNeed built simply just runs off the system Loyce has already built.
I think he is putting all the data together file by hand.
I'm assuming he uses a script to build it.
