Question

I have a csv file, a big one, 30 000 rows. I’ve tried to import it using LOAD file etc.. from the terminal, as I found on google, but it didn’t work. It was making the import but my table got to 30 000 rows of NULL cells.

After that I tried phpMyAdmin and there I found out that my csv was too big. I’ve split it in 5 using CSV Splitter. I’ve made the import for the first file. Everything went great. Than I tried to import the second one, but I got thos error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried
to allocate 35 bytes) in C:\xampp\phpMyAdmin\libraries\import\csv.php
on line 370

or 1064 error sometimes.

Do you know why and how can I solve it? Thank you.

Answer 1

Increase your php’s memory limit and script time, that’s beacause your executing the mysql instruction through the php server.

Check your php.ini file for this vars:

memory_limit
max_execution_time

But anyway I would do it through the mysql client (terminal), check mysql doc

LOAD DATA LOCAL INFILE '/path/to/your/csv/file/csv_file.csv' INTO TABLE database_name.table_name FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';
