从php运行mysql查询

Question

I am trying to run a MySQL query from a PHP script like this:

$q = "
UPDATE
  cf_ab_companies, inndata200
SET
  cf_ab_companies.col_158 = inndata200.AFakt_10_Fast_renhold, 
  cf_ab_companies.col_159 = IF ( inndata200.Startdato = "01.01.3000 00:00" OR inndata200.Startdato = "01.01.2000 00:00", NULL, str_to_date(inndata200.Startdato, '%d.%m.%Y')), 
  cf_ab_companies.col_160 = IF ( inndata200.Sluttdato = "01.01.3000 00:00" OR inndata200.Sluttdato = "01.01.2000 00:00", NULL, str_to_date(inndata200.Sluttdato, '%d.%m.%Y'))
WHERE
  cf_ab_companies.model_id = inndata200.ImportGOID;";

 mysql_query($q, $db);

But it seems that the query is not stored properly in PHP. What is the simplest way to store queries like this in PHP?

Thanks for all help

Answer 1

This should make it work; put slashes ( \\ ) before your quotes ( " ) because it gets confused:

$q = "
UPDATE
  cf_ab_companies, inndata200
SET
  cf_ab_companies.col_158 = inndata200.AFakt_10_Fast_renhold, 
  cf_ab_companies.col_159 = IF ( inndata200.Startdato = \"01.01.3000 00:00\" OR inndata200.Startdato = \"01.01.2000 00:00\", NULL, str_to_date(inndata200.Startdato, '%d.%m.%Y')), 
  cf_ab_companies.col_160 = IF ( inndata200.Sluttdato = \"01.01.3000 00:00\" OR inndata200.Sluttdato = \"01.01.2000 00:00\", NULL, str_to_date(inndata200.Sluttdato, '%d.%m.%Y'))
WHERE
  cf_ab_companies.model_id = inndata200.ImportGOID;";

Answer 2

I managed to solve it by following the advice by t.niese to escape the "'s

Thanks a lot!
