Hello,

I am facing some problem in passing data table parameter to stored procedure.

There are two table
tblQuestion and tblAnswerChoice

1. tblQuestion is for storing questions and its columns are
a)Qid int primary key identity
b)Question ntext
c)Createiondate datetime

2. tblAnswerChoice is for storing Answer Choices for the particular question and its columns are
a)Ansid int primary key identity
b)qid int
c)AnswerChoice ntext

Now about the problem I want to update the data of the tblAnswerChoiceI am passing the datatable as parameter to the datatabse. I need the stored procedure for updating the datatbase. Is is possible using table datatype or not. If yes then how to write the stored procedure for update the tblAnswerChoice. If table stored procedure is not use in this case, how can I update the tblAnswerChoice

Thanks,
Deepak Pandey

You type should be

SQL

CREATE TYPE [dbo].[tblAnswerChoiceTypeUpdate] AS TABLE(
    [AnsID]         int,
    [answerchoice] [ntext] NULL
)

The stored procedure should be

SQL

CREATE procedure [dbo].[spUpdateAnswerChoice] @dtanswerchoice tblAnswerChoiceTypeUpdate READONLY as
Begin

    update tblAnswerChoice
    set AnswerChoice=@dtanswerchoice.answerchoice
    from tblAnswerChoice,@dtanswerchoice
    where tblAnswerChoice.AnsID=@dtanswerchoice.AnsID

End

Hope this helps
