在没有主键的情况下更新当前在MYSQL表上获取的数组PHP

Question

I have a MySQl table with large number of columns without a primary key. It is been imported via an external csv file.

I have a php code which fetches cell values from the current row modifies them and have to replace/update the current row itself. I fetch the results simply by iterating through individual rows.. however as there is no primary key.. i am unable to modify the cell value.

However, since there is no primary key, but php is fetching the current row, i just want to update the current row being fetched. How can we grab the current row?

Thank You.

Answer 1

If you're importing this from a csv file, I would recommend you to add a new "ID" column to the csv file. Set each value in that column to be a unique number (most likely the row number). Then, when you import it into mysql, you'll have a unique row identifier to work with.

如果您使用的是phpmyadmin，我建议您创建一个“ ID”字段以使您的任务更轻松
