您好我正在尝试使用 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;
?>

当我运行此页面并刷新它时，记录只插入一次。（txnid 是主键，我每次都会更改它。）我无法知道我哪里出错了。

您的代码运行良好。因为我使用的是 ubunthu 框，所以我只是将表名大写。（您的创建表语句提供了 CUST_TXN 表名）

<?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;
?>

结果

您也可以将 current_timestamp 用于您的 txn_time 列

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) );

<?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;
?>

结果

$txnid 听起来像时间戳。mysql可以自动插入。设置为

ALTER TABLE CUST_TXNCHANGE txnid txnidTIMESTAMP ON UPDATE CURRENT_TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP。

您将不再在代码中设置时间戳。
