我在php中有一个mysql查询，设置为每小时由一个cron作业运行。有时结果是正确的，有时我会得到一个与查询不同的日期的结果。由于mysql正在不同的时区运行，我使用php date() time()来纠正当前的小时和日期。我首先在mysql中使用count来查看是否存在符合条件的任何记录。如果他们这样做我运行相同的查询并获取数据。我正在寻找当天的记录。有一个时间框架，比当前时间早一个小时或一个半小时，并匹配其他几个参数，即JobStatus和TechID列。有时它运行正常，有时我会得到记录显示未来几天。数据库中时间的列是一个varchar，因为我只需要当前时间来匹配字符串，因为约会作为1PM或9:30AM或者date_default_timezone_set("America/Chicago");
$SearchDate = date('Y-m-d', time());
//CURRENT TIME PLUS ONE HOUR
$TimePlusHour = date('gA', strtotime("+1 hours"));
//CURRENT TIME PLUS ONE HOUR PLUS SETTING MINUTES TO HALF HOUR
$Plus30 = date('g:30A', strtotime("+1 hours"));
$sqlCount = "SELECT COUNT(*) AS 'count' FROM ServiceTickets WHERE Date=
'".$SearchDate."' AND Time='".$Plus30."' OR Time='".$TimePlusHour."'
AND JobStatus='1' OR JobStatus='3' AND TechID= '".$TechID."' ";
$sql1 = "SELECT * FROM ServiceTickets WHERE Date= '".$SearchDate."' AND
Time='".$Plus30."' OR Time='".$TimePlusHour."' AND JobStatus='1' OR
JobStatus='3' AND TechID= '".$TechID."' ORDER BY id ASC";
或者选择的任何时间段输入到数据库中表格以小时或半小时为准。我也在下面添加了我的数据库结构。我检查了数据库，看看它是否已损坏，并且检查结果正常。
我可能会错误地查询此查询吗？

答案 0 :(得分：1)
在调用AND和OR时，您的查询很混乱，我首先将OR放在括号中
$sqlCount = "SELECT COUNT(*) AS 'count' FROM ServiceTickets WHERE Date=
'".$SearchDate."' AND (Time='".$Plus30."' OR Time='".$TimePlusHour."')
AND (JobStatus='1' OR JobStatus='3') AND TechID= '".$TechID."' ";
$sql1 = "SELECT * FROM ServiceTickets WHERE Date= '".$SearchDate."' AND
(Time='".$Plus30."' OR Time='".$TimePlusHour."') AND (JobStatus='1' OR
JobStatus='3') AND TechID= '".$TechID."' ORDER BY id ASC";
