trying to load maxmedia geocity lite's (free) large csv files using a blogger's php code (have x'd values). i've ftp uploaded this file to server, and created link to it from webpage, thinking that would "activate" it somehow (i'm a newbie). in phpadmin/mysql, i'm creating "csv" table with 1 field and naming it "blocks" although that's probably not the right thing to do (would rather have the code populate/make the table, but don't know how to do that). anyhow the csv file is freezing/not loading through import.

using php/mysql on local machine was a headache previously so i'm doing all of this via remote server (ftp/phpadmin/mysql=godaddy).

please help, thanks.

Code: [Select]

$databasehost = “xxx”;
$databasename = “xxx”;
$databasetable = “csv”;
$databaseusername =”xxx”;
$databasepassword = “xxx”;
$fieldseparator = “,”;
$lineseparator = “\n”;
$csvfile = “GeoLiteCity-Blocks.csv”;

Try LOAD DATA INFILE syntax

[paulmo]

thanks, how to do that please?

[Mchl]

MySQL manual has some info

[paulmo]

ok i found the page:
http://dev.mysql.com/doc/refman/5.0/en/load-data.html

guessing i do that in the "sql query" box?

since csv file is on my computer, how is this loaddata method going to get the file from my computer? there's no mention of an upload method here; it seems to be written as if the file is already in the database.

[Mchl]

If you use PhpMyAdmin, you can do this in 'Import' tab, where you can upload file to server. Otherwise you must upload file using ftp.

If the file is large, you might have to split it into several smaller, because there probably is a limit set up on your host for both upload file size and script execution time.

[paulmo]

yes there is a limit; 2,000 kbs in import. the files are 99k and 11k. how to split up csv files. thanks

[corbin]

You could just grant an account with your IP or a wild card host access.  Then, you could use the mysql shell tool (mysql or mysql.exe) to connect to it.  Then you could issue the LOAD DATA command from the shell, and it could use a local file.

[Mchl]

Alternatively, if you have access to PhpMyAdmin's config.inc.php file, you can set up an upload directory in $cfg['UploadDir']
Then upload your files to this directory using ftp. You will then be able to select them within your import dialog.

[paulmo]

thanks mchl and corbin: those sound like good things to learn. i don't know the first thing about granting an ip acc't or wild card access. i'm guessing this method involves queries in the sql window, which i know little about unless i see the code. the second option sounds good to learn too: i'm unsure about the config file or how to find that in phpmyadmin, and the steps to set up a directory.

thanks for advice. i'm new at this besides creating one table that gets values (insert into) from a form. 

[corbin]

You could use PHPMyAdmin to set the permissions.
