我在jsp文件中有日期選取器問題。如何在兩個日期之間獲取數據？
當我點擊Allmeters.jsp文件中的超鏈接時，它將打開meteridinfo.jsp。在這個文件中，我有一個名爲meterid的標籤。我從allmeters.jsp獲得這個meterid值，並且我還有兩個字段叫fromdate和todate。通過使用這些日期，我從MySQL表中獲取數據，但問題是，當我選擇fromdate作爲2012-05-1和todate作爲2012-05-11它不是retreiving數據，但是當我將todate更改爲2012-05-31那麼它顯示來自mysql表的數據，這意味着當我選擇一個月的最後一天作爲todate，那麼只有它來了。請幫助我。
AllMeters.jsp的值編碼在下面給出：

在MySQL表我有日期值如下： 2012-05-10， 2012-03-04， 2012-03 -04， 2012-09-12， 2012-09-12， 2012-09-12， 2012-09-12。
你應該張貼只有相關的代碼。 – Raptor
