Need help in update query

Question

Hi,

This update query is not working. Can anyone help me with this one.

command.CommandText =

"UPDATE [Root_Cause_App_Rsn_Lookup] SET [Root_Cause_Grp_Cd]='" + RootCauseGroup + "', [Root_Cause_App_Rsn_Cd]='" + RootCauseAppReason + "', [Root_Cause_App_Rsn_Desc]='" + RootCauseAppReasonDescription + "' WHERE ([Root_Cause_Grp_Cd)= '" + RootCauseGroup +"')";
