Load data infile default value not inserting in table

Question

I'm importing a csv file using LOAD DATAINFILE

The csv columns are NAME,TYPE,STATUS

my table structure is

Name  : varchar
TYPE  : Varchar
Status: Tiny int default value 1

I use this stmt :

LOAD DATA INFILE '/var/www/names.csv' 
INTO TABLE users FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 LINES 

When I use the above statement it has to insert the status value as 1 for each row, but it is not inserting the same. Please advise.

Answer 1

When loading a file, MySQL expects that it has the same number of columns as the destination table, unless you specify otherwise, even if the missing column has a default value. So supply a column list to your LOAD statement, and a literal 1 for the value of STATUS :

LOAD DATA INFILE '/var/www/names.csv' 
INTO TABLE users 
  FIELDS TERMINATED BY ',' 
  ENCLOSED BY '"' 
  LINES TERMINATED BY '\n' 
  IGNORE 1 LINES 
  (`name`, `type`, 1)

You can also do it with a SET clause:

LOAD DATA INFILE '/var/www/names.csv' 
INTO TABLE users 
  FIELDS TERMINATED BY ',' 
  ENCLOSED BY '"' 
  LINES TERMINATED BY '\n' 
  IGNORE 1 LINES 
  (`name`, `type`)
  SET `status` = 1

Answer 2

After you execute the query , check for any warnings using

show warnings

Default value is 0 for numeric data types and '' for strings.

So you should have set default value 1 while creating the table

create table tableName
(
name nvarchar(100) not null,
type nvarchar(100) not null,
status smallint default 1
);
