Php 在MySQL插入方面有点困难

嗨，我正在尝试一个php代码将记录插入表中

<?php
$server = "localhost";
$user = "root";
$pwd = "";
$db_con = mysql_connect($server,$user,$pwd);
$select_db = mysql_select_db("test_database",$db_con);
$txnid = date ("ydmHis") . mt_rand(1000, 9999);
$custnumber = "4316010100000001";
$cust_mo_num = "7875432990";
$bc_id = "LTH001";
$timestamp = "12:12:12:12:12:12";
$amounta = "500";
$txnupdate = "INSERT INTO cust_txn (txnid,cust_num,cust_mo_num,bc_username,txn_time,txn_amount,txn_type,txn_status) VALUES ('$txnid','$custnumber','$cust_mo_num','$bc_id','$timestamp','$amounta','WTH','SUCC')";
$result = mysql_query($txnupdate);
mysql_close($db_con);
echo $result;
?>

---

您的代码运行正常。因为我使用的是ubunthu框，所以我只是将表名大写。（create table语句随CUST_TXN表名一起提供）

<?php
$user = "root";
$pwd = "root123";
$db_con = mysql_connect($server,$user,$pwd);
$select_db = mysql_select_db("ci",$db_con);
$txnid = date ("ydmHis") . mt_rand(1000, 9999);
$custnumber = "4316010100000001";
$cust_mo_num = "7875432990";
$bc_id = "LTH001";
$timestamp = "12:12:12:12:12:12";
$amounta = "500";
$txnupdate = "INSERT INTO CUST_TXN (txnid,cust_num,cust_mo_num,bc_username,txn_time,txn_amount,txn_type,txn_status) VALUES ('$txnid','$custnumber','$cust_mo_num','$bc_id','$timestamp','$amounta','WTH','SUCC')";
echo $txnupdate;
$result = mysql_query($txnupdate);
mysql_close($db_con);
echo $result;
?>

<?php
$user = "root";
$pwd = "root123";
$db_con = mysql_connect($server,$user,$pwd);
$select_db = mysql_select_db("ci",$db_con);
$txnid = date ("ydmHis") . mt_rand(1000, 9999);
$custnumber = "4316010100000001";
$cust_mo_num = "7875432990";
$bc_id = "LTH001";
$amounta = "500";
$txnupdate = "INSERT INTO CUST_TXN_2 (txnid,cust_num,cust_mo_num,bc_username,txn_amount,txn_type,txn_status) VALUES ('$txnid','$custnumber','$cust_mo_num','$bc_id','$amounta','WTH','SUCC')";
echo $txnupdate;
$result = mysql_query($txnupdate);
mysql_close($db_con);
echo $result;
?>

您还可以对txn\u时间列使用当前\u时间戳

MYSQL DDL

CREATE TABLE CUST_TXN_2 ( txnid char(16), PRIMARY KEY(txnid), cust_num char(16), cust_mo_num char(10), bc_username char(6), txn_time timestamp DEFAULT CURRENT_TIMESTAMP, txn_amount varchar(10), txn_type varchar(5), txn_status varchar(10) );

$txnid听起来像是时间戳。Mysql可以自动插入它。设为

更改表
CUST\u TXN
CHANGE
txnid
txnid
TIMESTAMP ON UPDATE CURRENT\u TIMESTAMP NOT NULL默认当前时间戳

您将不再在代码中设置时间戳。
（txnid是主键，我每次都会更改它。）“如果这是真的，那么您发布的代码与正在运行的代码不同。你发布的代码显然不起作用。但是如果我们不知道它与您发布的代码有什么不同，那么在您的实际代码中可能有点难以看到问题。您可以发布您的实际代码吗？在mysql控制台中运行下面的命令后，在这里发布您的CREATETABLE语句。显示创建表cust_txn；mysql_select_db（“test_数据库”$con）$sql5=“创建表CUST_TXN（txnid char（16）、主键（txnid）、CUST_num char（16）、CUST_mo_num char（10）、bc_username char（6）、TXN_time varchar（18）、TXN_amount varchar（10）、TXN_type varchar（5）、TXN_status varchar（10））；//如果（mysql_query（$sql5，$con））{echo“CUST_TXN Table created\r\n；echo”
