mysql LOAD DATA INFILE with auto-increment primary key

Question

I am trying to load a data file into mysql table using \"LOAD DATA LOCAL INFILE \'filename\' INTO TABLE \'tablename\'\".

The problem is the source data file contains dat

Answer 1

the column list must be at the very end and id column must have a set=null to be auto incremented – unfortunately the mysql documentation is very vague. they justt say col1, col2, but are those in the source file or in the dest table . This page helped a lot by clear examples.

Answer 2

Use the following query in case the csv record is like that

"21231","234424","My Category","1"

LOAD DATA LOCAL INFILE 'C:/wamp/www/cakephp/app/webroot/files/product_catalogs/categories.csv' INTO TABLE cats FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' (category_id,parent_id,category,is_leaf)

I have done that successfully. :)

Answer 3

Specify a column list:

By default, when no column list is provided at the end of the LOAD DATA INFILE statement, input lines are expected to contain a field for each table column. If you want to load only some of a table's columns, specify a column list:

LOAD DATA INFILE 'persondata.txt' INTO TABLE persondata (col1,col2,...);

Answer 4

your data file should look like this: null, study chars, other fields... MySQL will insert incremented id istead of null

Answer 5

LOAD DATA LOCAL INFILE '/var/www/.........../file.csv' INTO TABLE table_name FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\\r\\n' (field1,field2,.........,fieldn)
