SQLserver模糊查詢

? ? ? ? ? 考試的后臺監控中，查詢考生的登錄情況，模糊查詢考生信息。

? ? ? ? ??對于根據查詢出來的該考試、考場或者班級的所有考生信息，從中進行模糊查詢，可以模糊匹配學號、姓名、狀態、學院或者專業信息。

? ? ? ? ??首先，前臺將用戶輸入的字符串傳到后臺。

? ? ? ? ??代碼如下

<script>//獲取用戶輸入的字符串var value = $('#txtSearch').searchbox('getValue');function doSearch(value,name) {var value = $('#txtSearch').searchbox('getValue');var ExamID = $('#ExamID').val();var ExamPlaceID = $('#ExamPlaceID').val();var StartDate = $('#StartDate').val();var StartTime =$('#StartTime').val();$('#Chapter1').datagrid({url: '/Monitore/FuzzyQueryStudentInfo?strLike=' + value +"&ExamID=" + ExamID + "&ExamPlaceID=" + ExamPlaceID+ "&StartDate=" + StartDate + "&StartTime=" +StartTime});$("#Chapter1").datagrid("reload");//重新加載表信息datagrid}</script>

? ? ? ? ??這里，strLike即用戶輸入的字符串，其他的參數規定了查詢的范圍，即頁面當前顯示的學生信息。

? ? ? ? ??Controller代碼如下，包含了分頁

public JsonResult FuzzyQueryStudentInfo(){string t = Request.QueryString["strLike"];string ExamID = Request.QueryString["ExamID"];string ExamPlaceID = Request.QueryString["ExamPlaceID"];string StartDate = Request.QueryString["StartDate"];string StartTime = Request.QueryString["StartTime"];ExamDetailsViewModel studentinfo = new ExamDetailsViewModel{ExamID = ExamID,ExamPlaceID = ExamPlaceID,StartDate = StartDate,StartTime = StartTime};int pageSize = Request["rows"] == null ? 1 :int.Parse(Request["rows"]);int pageIndex = Request["page"] == null ? 10 :int.Parse(Request["page"]);int total = 0;string strLike = Request["strLike"].ToString().Trim();List<v_studentexaminfo> ListExamInformation = newList<v_studentexaminfo>();ListExamInformation =IexaminformationBll.FuzzyQueryStudentInfo(studentinfo, strLike, pageSize,pageIndex, out total).ToList();var data = new{total,rows = ListExamInformation};return Json(data, JsonRequestBehavior.AllowGet);}

? ? ? ? ??最后，使用模糊匹配like進行多字段的查詢。

? ? ? ? ??代碼如下

public List<v_studentexaminfo> FuzzyQueryStudentInfo(ExamDetailsViewModel studentinfo, string strLike, int pageSize, int pageIndex, out int total){List<v_studentexaminfo> configonclassList = new List<v_studentexaminfo>();try{MySqlConnection conn = MySQLHelper.GetConnection;string sql = "select * from (SELECT * FROM v_studentexaminfo WHERE ExamMainID=" + "'" + studentinfo.ExamID + "'" + " and ExamPlaceID=" + "'" + studentinfo.ExamPlaceID + "'" + " and StartDate=" + "'" + studentinfo.StartDate + "'" + " and StartTime=" + "'" + studentinfo.StartTime + "'" + ") aa where StudentNo LIKE'%" + strLike + "%' or StudentName LIKE'%" + strLike + "%' or State LIKE'%" + strLike + "%' or Colleage LIKE'%" + strLike + "%' or Major LIKE'%" + strLike + "%'";int begin = pageSize * (pageIndex - 1);DataTable dt = MySQLHelper.ExecuteDataTable(sql);total = dt.Rows.Count;sql = sql + " limit " + begin + "," + pageSize;DataTable dt1 = MySQLHelper.ExecuteDataTable(sql);List<v_studentexaminfo> examdetailsinfo = ModelConvertHelper<v_studentexaminfo>.ConvertToModel(dt1).ToList();return examdetailsinfo;}catch (Exception){throw;}}
