Question

我想知道是否有人可以验证我的代码，在Linux服务器上运行此代码时，我似乎遇到了一些问题。

如果我运行这个本地主机（Xammp）这样运行没有任何错误，没有超时。

脚本创建数据库并从TXT或CSV填充。

当我将脚本移动到Web服务器以运行时我最终得到以下错误：

Error creating table: Table 'Sales' already exists
Error: LOAD DATA INFILE 'Salest.CSV' REPLACE INTO TABLE `Sales` FIELDS TERMINATED BY ',' IGNORE 1 LINES
Access denied for user 'USERNAME'@'%' (using password: YES)

我拒绝访问？但如果我删除表格：并重新运行代码：

Table Sales created successfully
Error: LOAD DATA INFILE 'Salest.CSV' REPLACE INTO TABLE `Sales` FIELDS TERMINATED BY ',' IGNORE 1 LINES
Access denied for user 'USERNAME'@'%' (using password: YES)

当然用户名和密码是正确的，因为它在数据库中创建了表，为什么我在填充它时会遇到问题？

我错过了什么？

Answer 1

因此经过大量的反复试验，我能够解决问题。

$sqlimport = "
LOAD DATA INFILE '$filename'

替换为：

$sqlimport = "
LOAD DATA LOCAL INFILE '$filename'

给我一个新的错误沿着本地命令的行不允许使用MySQL版本。 SQL语句：SHOW VARIABLES LIKE'local_infile' 给我结果：local_infile OFF

宾果!!!更改为On，重新启动并且脚本按预期工作。

感谢您的帮助和建议。

PHP - 将TXT / CSV导入SQL的LoadIn文件在服务器上不起作用，但在本地工作？
