基于$ curr_time-> format的SQL语句('Ymd H:i')

Question

为什么这个代码......

$curr_time = new DateTime();
$query_inprocess = "UPDATE `MyTable` 
                    SET inprocess=1 
                    WHERE startTime <= '" .$curr_time->format('Y-m-d H:i') . "'";

...导致错误的SQL查询,其中后面的语句<被忽略？

UPDATE `MyTable` SET inprocess=1 WHERE startTime <

Answer 1

尝试这个

$curr_time = new DateTime();
$query_inprocess = "UPDATE `MyTable` 
                    SET inprocess=1 
                    WHERE startTime <='" .$curr_time->format('Y-m-d H:i'). "'";//OR use date('Y-m-d H:i') instead of $curr_time->format('Y-m-d H:i')
