sorry found at mysql docs BIT <https://dev.mysql.com/doc/refman/5.7/en/bit-type.html> 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 <https://dev.mysql.com/doc/refman/5.7/en/bit-type.html> column properly: <https://dev.mysql.com/doc/refman/5.7/en/load-data.html> 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? 2015-11-02 21:43 GMT-02:00 Roberto Spadim <roberto@spadim.com.br>:
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?)
