asp.net - GridView update causes "incorrect syntax near 'nvarchar'" error -


i have major problem when trying use update in gridview. code below, once click 'edit', option change 'kpi' name , 'current target'. but, once click 'update', error message:

incorrect sysntax near 'nvarchar'

here markup:

<p>     <br />     <asp:dropdownlist id="groupselection" runat="server" datasourceid="group" datatextfield="fcstgroup"         datavaluefield="fcstgroup">     </asp:dropdownlist> </p> <p>     <asp:gridview id="gridview2" runat="server" datasourceid="sqldatasource1">         <columns>             <asp:commandfield showeditbutton="true" />         </columns>     </asp:gridview> </p> <p>     <asp:sqldatasource id="sqldatasource1" runat="server" connectionstring="<%$ connectionstrings:wfmconnectionstring3 %>"         selectcommand="select                              case _parameter.name kpi,                             [target]*100 [current target]                             _parameter inner join _reporting_group                             on _parameter.reporting_group = _reporting_group.id                              _reporting_group.name = @wg "  updatecommand="update _parameter set target = .80                                 reporting_group = (select id _reporting_group name = @wg)                                 , name = 'nco_i_e' ">         <selectparameters>             <asp:controlparameter controlid="groupselection" name="wg" propertyname="selecteditem.text" />         </selectparameters>         <updateparameters>             <asp:controlparameter controlid="groupselection" name="wg" propertyname="selecteditem.text" />         </updateparameters>     </asp:sqldatasource> </p> <asp:sqldatasource id="group" runat="server" connectionstring="<%$ connectionstrings:wfmconnectionstring3 %>"     selectcommand=" select     distinct _reporting_group.name fcstgroup         dbo._metrics inner join                     dbo._reporting_group on dbo._metrics.reporting_group = dbo._reporting_group.id "> </asp:sqldatasource>

i'm guessing problem update command, working correctly when ran in sql:

updatecommand="update _parameter set target = .80                                 reporting_group = (select id _reporting_group name = @wg)                                 , name = 'nco_i_e' ">

note that, @ moment, update command using fixed set 'target' value , fixed 'name' value. eventually, need use value entered in 'current target' , kpi value. but, once can figure out why i'm getting 'nvarchar' error message.

if can spot issue is, appreciate it.

the first thing jumps out @ me should change updateparameter this:

<asp:controlparameter controlid="groupselection" name="wg" propertyname="selecteditem.text" />

selecteditem.text not valid property (the .text should capitalized).

other things possibly cause problem data types in sql. if "target" column can't accept value of .80, or if "name" value can't accept whatever you're selecting in "groupselection" dropdownlist, possibly cause type of syntax error.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
