Hello I'm using LOAD DATA INFILE to populate a table in MySQL.
LOAD DATA INFILE 'test.txt'
INTO TABLE myTestTable
FIELDS TERMINATED BY '\t'
IGNORE 1 LINES;
Everything is working peachy except that there is a datetime column in my data that is formatted without any delimiter between the date and time sections. Like so:
SomeDateColumn
20050101081946
When I read this in, MySQL replaces all the dates with dummy values. Is there a way to have MySQL read this in correctly straight from a file?
Thanks!
You may call STR_TO_DATE when you run LOAD DATA, and convert the text date to a bona fide date on the fly:
LOAD DATA INFILE 'test.txt'
INTO TABLE myTestTable
FIELDS TERMINATED BY '\t'
IGNORE 1 LINES
(
col1, col2, #var1 -- list out all columns here
)
SET SomeDateColumn = STR_TO_DATE(#var1, '%Y%m%d%h%i%s');

I have data with date format 1577234966837.
I uploaded this data in table via command :
load data infile 'C:/file.tsv'
into table table_1
fields terminated by '\t'
lines terminated by'\n'
ignore 1 lines (value, #timestamp)
set timestamp = FROM_UNIXTIME(#timestamp);
Command successful, but value in column timestamp is null. Ho to upload this format?
Your code looks right, but have problem with data type convertation.
In MySQL unixtime is number of second from 1970-01-01 00:00:00.
In your case number looks as JavaScript time in milliseconds, so for right convertion you should to divide the number by 1000
select from_unixtime(1577234966837); -- result is NULL
select from_unixtime(1577234966837/1000); -- result 2019-12-25 00:49:26.8370

So right import command should be like:
load data infile 'C:/file.tsv'
into table table_1
fields terminated by '\t'
lines terminated by'\n'
ignore 1 lines (value, #timestamp)
set timestamp = FROM_UNIXTIME(#timestamp/1000);
I would like to convert MySQL string to required date format .
I have below lines in a file.
30-06-2017,clarke
31-07-2018,warner
my table is having 2 columns .
Column1 datatype :: date
Column2 datatype :: varchar(30)
I have executed below query
load data local infile 'test.txt' into table sample fields terminated by ',' set column1=str_to_date(#c1,'%d-%m-%Y') ;
Column1 data was not loaded and I got below warnings.
Data wad truncated for column1 at row1
May I know what is wrong in the sql query which I am using ?
You have to include the columns (#c1, #c2) from the file. Following command works fine.
LOAD DATA LOCAL INFILE 'test.txt' INTO TABLE sample FIELDS TERMINATED BY ',' (#c1, #c2) SET column1=STR_TO_DATE(#c1,'%d-%m-%Y'), column2=#c2;
I need a way to use the UTC_TIMESTAMP() function in a CSV file.
Currently I'm using the following Syntax;
LOAD DATA INFILE '/path/to/file.csv'
INTO TABLE my_table FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n';
I'm not quite sure what to do to keep the UTC_TIMESTAMP() from being enclosed in quotes. When entered in the database, I get the following result
"0000-00-00 00:00:00"
This was the only example I could find on stack overflow or on Google for converting a string to a MYSQL value.
MySQL CSV import: datetime value
I solved the problem by following the MySQL documentation on this page.
https://dev.mysql.com/doc/refman/5.7/en/load-data.html
About halfway down the page there is a section that shows you how to create variables for rows and then set table rows equal to native mysql functions or values assigned to those variables(Whichever you choose).
The example in the documentation that I'm referring to looks like this.
LOAD DATA INFILE 'file.txt'
INTO TABLE t1
(column1, column2)
SET column3 = CURRENT_TIMESTAMP;
I fixed my problem by restructuring my code like this...
LOAD DATA LOCAL INFILE '/path/to/file.csv'
INTO TABLE veh_icodes FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(id, vcode, year, make, model, body_style, tran_type, engine_cap, drive_train, doors, trim, created_by, updated_by, #created_at, #updated_at, active)
SET created_at = CURRENT_TIMESTAMP, updated_at = CURRENT_TIMESTAMP;"
I hope this helps someone. :)
i use below script for insert data to sql from textpad.
#!/bin/bash
mysql --utest -ptest test << EOF
LOAD DATA INFILE 'test.txt'
INTO TABLE content_delivery_process
FIELDS TERMINATED BY ',';
EOF
in my test file i have a format like,
cast , date , name , buy
i can insert but i need format like below,
S.NO | date | name | buy | cast
You can specify the columns you want to import:
From the MySQL Manual:
MySQL LOAD DATA INFILE
The following example loads all columns of the persondata table:
LOAD DATA INFILE 'persondata.txt' INTO TABLE persondata;
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,...);
You must also specify a column list if the order of the fields in the
input file differs from the order of the columns in the table.
Otherwise, MySQL cannot tell how to match input fields with table
columns.
You would include "FIELDS TERMINATED BY '|';" at the end to import data delimited with a '|' symbol.
Hope this helps.
create table [YOUR TABLE] ( `S.NO` INT AUTO_INCREMENT, date DATETIME, name VARCHAR(50), buy VARCHAR(50), cast VARCHAR(50));
Load data local infile 'test.txt' ignore into table [YOUR TABLE] fields terminated by ',' lines terminated by '\n'(cast , date , name , buy);
I'm trying to convert timestamps on the fly when importing a csv file into mysql from string to datetime data type. But I am getting a #1411 - Incorrect datetime value: '2007-03-30 16:01:15' for function str_to_date error.
The SQL:
load data infile 'C:/ProgramData/MySQL/MySQL Server 5.5/data/testfile.csv'
into table test
fields terminated by ','
lines terminated by '\n'
(date, col1,col2,col3,col4)
SET
date = str_to_date(date,'%Y.%m.%d %H:%i:%s.%f');
All rows in the .csv are formated like this:
2007.03.30 16:01:15.901,117.53,117.55,35600000,43700000
I've applied
SELECT str_to_date(date,'%Y.%m.%d %H:%i:%s.%f') FROM test
to sample data that was already stored in mysql, it did work.
The target row date is set to DATETIME.
You need to go via a user variable. As the manual says:
The column list can contain either column names or user variables. With user variables, the SET clause enables you to perform transformations on their values before assigning the result to columns.
User variables in the SET clause can be used in several ways. The following example uses the first input column directly for the value of t1.column1, and assigns the second input column to a user variable that is subjected to a division operation before being used for the value of t1.column2:
LOAD DATA INFILE 'file.txt'
INTO TABLE t1
(column1, #var1)
SET column2 = #var1/100;
In your case:
LOAD DATA INFILE 'C:/ProgramData/MySQL/MySQL Server 5.5/data/testfile.csv'
INTO TABLE test
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
(#date, col1, col2, col3, col4)
SET date = STR_TO_DATE(#date, '%Y.%m.%d %H:%i:%s.%f');
