hi justing, but i always get 1
even when data file have "0" (character "0") at line

i'm reading the load data file:
https://github.com/MariaDB/server/blob/e19a6f3dca7509eb8e042796a9311dba937ad9d7/sql/sql_load.cc#L853
that's something with field->store (i think)
field->store((char*) pos,length,read_info.read_charset);

https://github.com/MariaDB/server/blob/e19a6f3dca7509eb8e042796a9311dba937ad9d7/sql/sql_load.cc#L1025
field->store((char*) pos, length, read_info.read_charset);
i didn't checked yet store of bit field type

Hi,

Instead of using b'...' notation, use bitwise math to get the integer representation of the bitset, and place that in your loader file.

For example:
select 1 | 2 | 8;  ---> 11

Put 11 in your data file and you will get bits 1 2 and 8 set in your bitset.

sorry found at mysql docs

BIT values cannot be loaded using binary notation (for example, b'011010'). To work around this, specify the values as regular integers and use the SET clause to convert them so that MySQL performs a numeric type conversion and loads them into the BIT column properly:

shell> cat /tmp/bit_test.txt 2 127 shell> mysql test mysql> LOAD DATA INFILE '/tmp/bit_test.txt' -> INTO TABLE bit_test (@var1) SET b = CAST(@var1 AS UNSIGNED); Query OK, 2 rows affected (0.00 sec) Records: 2 Deleted: 0 Skipped: 0 Warnings: 0

but i'm checking something very bad
if i execute without "SET" a big file take 1second, with "SET" it takes 3 times more
maybe we could include the bit cast at load data infile and solve this problem? maybe a mariadb improvement?

hi guys, how could i send bit data to mysql with LOAD FILE?

a table example:
create table t (i bit not null default 0);

LOAD DATA LOCAL INFILE "file.csv" IGNORE INTO TABLE `t` FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n' (i)


the data file is simple:

0
1
0
1
0
1

but i got Warning 1024: Out of range value for column 'i' at row 1 ... to last row

any idea? i tried 
b'0'
b'1'
'0'
'1'
0
1
but no one work, i don't know what happen but it's cast always to 1  (maybe convert from string to binary?)
