StackOverflowers!
I have an issue when trying to import a .csv
file into a table.
As far as I know (and as I've read in the reference manual), the syntax is something like this:
load data infile '/path/to/my/file.csv'
into table myTable(field1, field2, field3,..., fieldk)
fields terminated by ',' optionally enclosed by '"'
lines terminated by '\n'
ignore 1 lines;
However, MySQL client throws this error:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'fields terminated by ',' optionally enclosed by '"' lines terminated by '\n'
I need to specify the column list, because my table has a column that are not present in the file (the id
column).
I've checked (and rechecked) the syntax, and everything seems ok... so I don't have a clue what could be wrong. I've tried enclosing the field names in backticks (`) but it doesn't work either... Is the field list wrong? Do I need to specify something I'm missing?
Background info:
- OS: Debian 7.5 (wheezy), 64-bit
- MySQL version: 5.5.37-0+wheezy1
- All tables are MyISAM
Attempted solution:
I could, of course, create a temporary table and drop the "problematic" column. I've tested this solution, and it works:
drop table if exists temp_myTable;
create temporary table temp_myTable like myTable;
alter table temp_myTable drop column id;
load data infile '/path/to/my/file.csv'
into table temp_myTable
fields terminated by ',' optionally enclosed by '"'
lines terminated by '\n'
ignore 1 lines;
insert into myTable (field1, field2, ... fieldk)
select field1, field2, ... fieldk
from temp_myTable;
drop table if exists temp_myTable;
However, I think this is quite cumbersome... why should I write 6 instructions when I should be able to solve it with one?
Could you help me?
回答1:
After reading more carefully the reference manual, I found that the right way to write the column list is at the end of the sentence:
load data infile '/path/to/my/file.csv'
into table myTable
fields terminated by ',' optionally enclosed by '"'
lines terminated by '\n'
ignore 1 lines
(field1, field2, field3,..., fieldk); -- The field list goes here
Right now, I'm feeling really dumb... but I put this knowledge here, just in case anyone is facing this same issue.
