Question

我有这句话。在我需要公司字段为“ stackoverflow”而不是CSV值的地方。

上传的csv

alice,bob,support@stackoverflow.com,+3233232,companyx,appointment
alice1,bob1,support1@stackoverflow.com,+3233232,companyy,appointment

SQL：

$sql = <<<eof
  LOAD DATA INFILE '$target_path'
   INTO TABLE sh_contact
   FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
   LINES TERMINATED BY '\n'
  (firstname,lastname,email,mobile,company,type)
eof;

编辑：

LOAD DATA INFILE '$target_path'
INTO TABLE sh_contact
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(firstname, lastname, email, mobile, company, type)
SET company = 'stackoverflow', type='blabla';

Answer 1

在company列中使用变量占位符，然后将公司手动覆盖为Stack Overflow：

LOAD DATA INFILE '$target_path'
INTO TABLE sh_contact
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(firstname, lastname, email, mobile, @var, type)
SET company = 'stackoverflow';

在这种情况下，您甚至可能不需要使用@var。无论如何，您不需要知道输入值是什么，因为您打算覆盖它。
