Hi Alex,
It is true that use LOAD DATA INFILE you do need to know the schema of the
table. I'm not sure how useful it would be to import arbitrary data if you
don't have some expectations about what that data is. There are a couple
options for you:
1. Make sure your users upload a CSV is a specific format, reject
non-conforming input.
2. Let your script transform the user uploaded CSV file into the format the
database is expecting.
3. Have your script simply parse the user uploaded CSV and generate insert
statements as needed. Just because you want to accept CSV from your app, does
not mean you must use LOAD DATA INFILE to get the data into MySQL.

Gavin Towey

Subject: Re: load data into temporary table
Thank you but the real problem occurs when you don't know the schema
of the table in advance. If data.txt has two columns columns how can I
still load it in a temporary table? I'm asking this question because
I'd like to add an import csv feature to a web application. I know
that you can load data infile into table without specifying the schema
of this table but it does not look like you can do load data infile
into a temporary table.
Thank you,
Alex
