how to load data into a table?

hosefo81 · October 31st, 2003, 11:17 PM

i am using mysql version 4 and have created a text file `pet.txt' containing one record per line, with values separated by tabs, and given in the order in which the columns were listed in the CREATE TABLE statement. For missing values i represent it with \N (backslash, capital-N). i save the file in my root document for web server which is C:\Inetpub\wwwroot\project.

To load the text file `pet.txt' into the pet table, i use this command:
LOAD DATA LOCAL INFILE "pet.txt" INTO TABLE pet;

but i get this error.
ERROR: File 'pet.txt' not found (Errcode: 2)

Is this because i save my pet.txt in the wrong directory? is yes, where should i save it?
Please help!

Hi hosefo,

There is a lengthy page all about this in the MySQL manual. My suggestion is give it a good study.

Quote from the manual page:

Quote:

quote:
When locating files on the server host, the server uses the following rules:

If an absolute pathname is given, the server uses the pathname as is.
If a relative pathname with one or more leading components is given, the server searches for the file relative to the server's data directory.
If a filename with no leading components is given, the server looks for the file in the database directory of the current database.

So whatever directory that the database itself is located in is where the text file needs to be saved, or you can just plug in the tried and true absolute path.

I already put the pet.txt file in the directory that the database itself is located but i still can't load that file. i still get the error below
ERROR: File 'pet.txt' not found (Errcode: 2)

I think that this may have something to do with your use of the 'LOCAL' keyword. The manual page stipulates that the LOCAL keyword will load a file from the standpoint of the client-side... MySQL sends a request to the client-side program and requests it to upload that file. So in order to use LOCAL I think that you would need to use an absolute path. If the LOCAL keyword is not specified then MySQL will look for the file from the server-side standpoint, whereas you may access the file from the database directory, a relative path from the root www directory (methinks anyhow, the manual says the server data directory), or an absolute path.

That's my suspicion. The manual page also mentions security settings that need to be in place before accessing the file server-side will be possible.

If you want to stay with the LOCAL keyword, plug in an absolute path. Which would be something like this.

C:\\Inetpub\\wwwroot\\project\\pet.txt
