如何在mysql中选择日期范围？

Question

我想在mysql中选择一个日期范围.

$dateFrom='2016-01-01';
$dateTo='2016-01-02';

不工作

query ="SELECT ".$name.",timestamp FROM people where age=".$age." AND timestamp>=".$dateFrom." AND timestamp<.$dateTo";

工作

query ="SELECT ".$name.",timestamp FROM people where age=".$age." AND timestamp>='2016-01-01' AND timestamp<'2016-01-02';

Answer 1

你需要把'单引号arround date变量.

query ="SELECT ".$name.",timestamp FROM people where age=".$age." AND timestamp>='".$dateFrom."' AND timestamp<'".$dateTo."';

确保您对SQL注入攻击持开放态度,您应该更好地使用Prepared语句来避免相同的情况.
