Add NOW() and file name of csv into same mysql column

Question

on import I want to put the name of csv and date of imported in the same column name,

On my code i have and error because $filename and NOW() cannot be in same column on thist code:

"LOAD DATA LOCAL INFILE '$filename' 
INTO TABLE $databasetable 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(name, firstname)
SET batch = $filename NOW() ");

Answer 1

这可以通过使用mysql CONCAT函数来解决：

SET batch = CONCAT($filename, ' ', NOW())

Answer 2

You need to properly concatenate the $filename's value with that of now(). Honestly, I would do this in php, not in sql, but you can do this in sql as well:

SET batch = CONCAT('$filename ', NOW())

In php:

$t=date(DATE_ATOM)
...
SET batch = '$filename $t'
