How can I get rid of these null columns? I'm importing my csv file to create a table on phpMyAdmin. The sql query looks appropriate but at the end, I get...

`Category 1` VARCHAR( 97 ) ,
`Category 2` VARCHAR( 113 ) ,
`NULL` VARCHAR( 71 ) ,
`NULL` VARCHAR( 56 ) ,
`NULL` VARCHAR( 73 ) ,
`NULL` VARCHAR( 97 )
) ENGINE = MYISAM DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

MySQL said: 

#1060 - Duplicate column name 'NULL'

Category 2 should be the last column. I can't figure out where the null columns are coming from, or how to get rid of them. The original file is given to me in .xls format. I make some changes and save as csv. I used to upload an xls file (never had problems) but I think our cPanel was upgraded so it's all changed.

So far I've tried deleting 4+ columns at the end while in OpenOffice. I've tried opening the csv in notepad and making sure there was no extra commas or spaces, adding in / to escape. I've tried fiddling with the import options in phpMyAdmin but I'm far from an expert so no luck there.

对我来说，我必须选择：

用,分隔的列

用"括起来的列

列转义为“

以auto终止的行

并检查文件的第一行包含表列名

遇到了这个问题，对我来说修复它的方法不是很直观。

在导入设置中，我检查了用[ " ]括起来的列。

这似乎解决了它并且所有导入都很好（据我所知）。

我上传了两个 cvs 也有类似的情况。PHPMyAdmin 抱怨一个最后有 2 个 NULL 列，另一个有 6 个。我以为我会通过添加额外的假列来“修复”它，但没有。

原来有些数据有双引号，让mysql误以为列数错误。

只需要检查所有数据以确保它是干净的......我知道它更多的是一种解决方法而不是修复。但我能在短时间内做到最好。

在我的情况下：我将列分隔符从“更改为”在格式特定选项中的 phpMyAdmin 中相同：从“更改为”
