sql server 2008 r2 throws error

msg 4145, level 15, state 1, procedure udspgetclfsearchresulteventlist, line 55
expression of non-boolean type specified in context condition expected, near ';'.

how can fix error? surely appreciated.

while true work...

declare @sql nvarchar(2000) = 'select ....  ....' declare @sqlwithwhere nvarchar(2000) set @sqlwithwhere = @sql + @whereclause exec sp_executesql @sqlwithwhere

...you should declare stored procedure parameters in c# , pass them individually. there risk of sql injection dynamic sql this. , more of hack standard approach.
