MySQL  Load data infile problem

I have a .txt file with a datetime field that i want to import into my MySQl 5.1 table using LOAD DATA INFILE. the datetime in the txt file is formatted like 12/2/2010 8:38:17 AM and when trying to import to the table it throws the error:
Data truncation: Incorrect datetime value: '12/2/2010 8:38:17 AM' for column 'DateLastModified' at row 1

I think that MySQL won't accept a datetime in that format??, it needs to be formatted to
2010/12/02  8:38:17 AM. So my question is how can I do this?

Hers my current code:
LOAD DATA INFILE '#replaceNoCase(ExpandPath( '/ftp/txt/photos_links.txt' ),"\","/","all")#' INTO TABLE nav.import_photolinks
            FIELDS TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '\t' ESCAPED BY '\\' lines terminated by '\r\n';

Any help appreciated!

sample on how to deal with differently-formatted dates:

load data infile '/tmp/xxx.dat'
into table xxx
fields terminated by '|'
lines terminated by '\n'
(col1,
col2,
@col3,
@col4,
col5)
set
col3 = str_to_date(@col3, '%m/%d/%Y'),
col4 = str_to_date(@col4, '%d/%m/%Y')
;

So you need to specify the columns, use @columnname for the date columns, then use set clause with str_to_date.  I'll update this comment in a few minutes for the formatting option you should use.

UPDATE:  for '12/2/2010 8:38:17 AM' you need '%m/%e/%Y %l:%i:%s'  See http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_date-format

Hi, I updated my code but I'm still getting the same error.
Error Executing Database Query.
 Data truncation: Truncated incorrect datetime value: '12/2/2010 8:38:17 AM'



LOAD DATA INFILE '#replaceNoCase(ExpandPath( '/ftp/txt/photos_links.txt' ),"\","/","all")#' INTO TABLE navica.photolinks
            FIELDS TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '\t' ESCAPED BY '\\' lines terminated by '\r\n'
        (PhotoLink, MLSNumber, PhotoLabel,@DateLastModified, PhotoOrder, DisplayAsPortrait) set DateLastModified = str_to_date(@DateLastModified, '%d/%m/%Y %I:%i:%s');

is the date feb 12, not dec 2?  Please note that there are different formatting options when you allow a single digit month/day/hour vs 01, 02, etc..  That's why I used lowercase L for hour, not capital I.  for month it's %c (not %m as I did above) and for day it's %e.

The problem is with 12 / 24 HR format.
Check this:
select str_to_date("12/2/2010 8:38:17 PM", "%d/%m/%Y %I:%i:%s %p");

Change:: str_to_date(@DateLastModified, '%d/%m/%Y %I:%i:%s %p');

I had noticed we didn't have the AM/PM handler, and added it myself

str_to_date(@DateLastModified, "%c/%e/%Y %l:%i:%s %p")

still doesnt work.

heres another datetime out of my txt file: 3/29/2012 3:27:56 PM, so its m/d/yyyy

that should match up with my code above but it is still throwing the same error?

I have the field type for DateLastModified set to datetime, that is correct right?

thanks for the help it is much appreciated!

In doing some more testing I actually updated my text file so that the datetime on the first row was 2010/12/02 8:38:17 AM and it still failed with the same error. If I set the field type to varchar the data will import without errors.

Created a /tmp/test that contained this:


2/12/2010 8:38:17 AM
3/29/2012 3:27:56 PM

Open in new window


Then did the following:


mysql> create table bang (a datetime);
Query OK, 0 rows affected (0.37 sec)

mysql> load data local infile '/tmp/test' into table bang (@a) set a=str_to_date(@a, "%m/%d/%Y %l:%i:%s %p");
Query OK, 2 rows affected (0.00 sec)
Records: 2  Deleted: 0  Skipped: 0  Warnings: 0

mysql> select * from bang;

One thing I found odd with your load data command is you have "FIELDS TERMINATED BY '\t' OPTIONALLY ENCLOSED BY '\t'" - not sure if having the same character to terminate and enclose works.  Anyway if you still need help I would like to ask for a dump of the table structure (or output of "show create table tablename") and a few lilnes of the input data.

I added an "ignore 1 lines", removed the "optionally enclosed by 't'", added @ to DateLastModified to "(PhotoLink, MLSNumber, PhotoLabel, @DateLastModified, PhotoOrder, DisplayAsPortrait)" and changed "%P" to "%p" in the date formatters.

If you have "optionally enclosed by '\t' it causes problems as mysql gets somewhat "confused" for the rows 12-15 where you don't have values for photo labels.:
mysql> LOAD DATA local INFILE '/tmp/sample.txt' INTO TABLE import_photolinks             FIELDS TERMINATED BY '\t'  optionally enclosed by '\t' lines terminated by '\r\n' ignore 1 lines         (PhotoLink, MLSNumber, PhotoLabel, @DateLastModified, PhotoOrder, DisplayAsPortrait) set DateLastModified = str_to_date(@DateLastModified,'%c/%e/%Y %l:%i:%s %p');

Bottomline, you shouldn't use the same character to enclose and terminate fields.

You're welcome.  Btw if you haven't noticed it yet my modified version of your LOAD DATA command is on the first line of my post above (http://www.experts-exchange.com/Database/MySQL/Q_27655955.html#a37796250). Just scroll to the right.  Thanks.
