joining tables in view
I am now concerned that I have not normalised the tables correctly as now I see no way to join them;
I have 1 table with 2 columns called Questions, and another table called answers with 10 columns, one for the userId then 9 columns which hold all the answers (int) for each user.
Everything is working well for inserts and updates, however I am having a heck of a time trying to create a view which will show all questions, each user and each of their responses to each question.
Question table;
CREATE TABLE [dbo].[Questions](
[questionId]开发者_JAVA百科 [int] IDENTITY(1,1) NOT NULL,
[question] [nvarchar](max) NULL,
CONSTRAINT [PK_Questions] PRIMARY KEY CLUSTERED
(
[questionId] ASC
)WITH (
PAD_INDEX = OFF,
STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON
) ON [PRIMARY]
) ON [PRIMARY]
Answer table;
CREATE TABLE [dbo].[Answers](
[empID] [nvarchar](10) NOT NULL,
[q1] [int] NULL,
[q2] [int] NULL,
[q3] [int] NULL,
[q4] [int] NULL,
[q5] [int] NULL,
[q6] [int] NULL,
[q7] [int] NULL,
[q8] [int] NULL,
[q9] [int] NULL,
CONSTRAINT [PK_Answers] PRIMARY KEY CLUSTERED
(
[empID] ASC
)WITH (
PAD_INDEX = OFF,
STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON
) ON [PRIMARY]
) ON [PRIMARY]
Nothing I have tried works, so any ideas from you all that can help me avoid re-doing the tables would be so greatly appreciated!
Thanks in advance for any help.

Seems to me that your answer table should have a foreign key to the question table. Unless an answer can refer to multiple questions, in which case I would say you should consider something like a mapping/relation table which has FKs to both answer and question tables.
I think you might need to look into pivot tables to accomplish your task.
