STR DATE与法语格式sql

Question

我的数据库中有一些日期是这样的： FCOL_DATE = 31/08/2007 00:00

我正在尝试进行此查询，但收到此错误： 解析错误：语法错误，

中意外的'％'

$from1 = "01/08/2013";
$to1 = "31/08/2013";

foreach ($query=$db->query("SELECT
t1.FCOL_ID, t1.FCOL_FRN_ID, t1.FCOL_DATE, t1.FCOL_PERIODE,
t2.STK_IDFACTCOLISAGE
FROM colisage t1
INNER JOIN mvt_stock t2
ON t1.FCOL_ID = t2.STK_IDFACTCOLISAGE
WHERE STR_TO_DATE(FCOL_DATE, "%d/%m/%Y") BETWEEN $from1 AND $to1 AND t1.FCOL_FRN_ID = $frnId") AS $donnees):
