           public IActionResult GetSearchedData([FromBody] dynamic DataObjectSearch)
                   string ReportId = DataObjectSearch.reportID;
                   string FromDate = DataObjectSearch.startdate;
                   string StartDate = FromDate.Substring(0, 10);
                   string todate = DataObjectSearch.enddate;
                   string EndDate = todate.Substring(0, 10);
                   string Searchdata = DataObjectSearch.searchstring;
                   var PostSearch = _reportservice.GetReportDetailsSearch(ReportId, StartDate, EndDate, Searchdata);
                   return Ok(PostSearch);

    When execute web api search string added to it double quotes why and how to solve issue ?

    I work on web api asp.net core 2.2 I face this error

    An expression of non-boolean type specified in a context where a condition is expected, near 'and'.

    procedure work from SQL success as below

    exec [dbo].[sp_ReportDetailsGetALL] "2028","2020-05-03","2020-05-11", 'Text6=''locations'''

    exactly issue on the following line


    not work if as below


    on web api i think it add double quotes on start and end so that it not work

    json i passed to web api as following :

    "startdate": "2020-05-03T22:00:00Z", 
    "enddate": "2020-05-11T22:00:00Z", 
    "searchstring": "'Text6=''MFG'''", 
    "reportID": "2028" 

    procedure getreportdetail as following :

    declare @ColumnName Nvarchar(max) = (SELECT 'select ' + STUFF((SELECT ',' + 'Text'+CONVERT(varchar(20),ReportHeaderIndex) + ' '+ '['+ReportHeader +']' 
    FROM ReportHeaders where ReportID=@ReportID order by ReportHeaderIndex 
    FOR XML PATH('')) ,1,1,'') + ' , convert(nvarchar(20),[ReportDate]) ReportDate From ReportDetails R where ReportDate >= ''' +@ReportDateFrom+''' and ReportDate <= '''+ @ReportDateTo +''' and R.ReportID =' + @ReportID + ' and '+@SearchString+' and IsHistory=0 order by reportdate desc ' + @SortingColumns AS Txt ) 
    exec (@ColumnName)

    Hi ahmedbarbary ,

    For reproducing the issue , what's your model design and the customized SQLDAL.ReturnDataTableByProcedure() method?

    If you want the community to review and debug the code , please share the relevant code that can reproduce the issue.

    Best Regards,

    You need to produce valid sql. Search string should be

    "searchstring": "Text6='MFG'",
