wish of those help I have table defined as follows: , Seems like this would work, I have not tested it thoroughly:
code :
CREATE TABLE [#TestTable]
(ID1 INT, ID2 INT, UQ AS
CASE WHEN [ID1] < [ID2] THEN CAST([ID1] AS VARCHAR(30)) + ',' + CAST([ID2] AS VARCHAR(30))
ELSE CAST([ID2] AS VARCHAR(30)) + ',' + CAST([ID1] AS VARCHAR(30)) END
)

CREATE UNIQUE NONCLUSTERED INDEX [IX_NCL_TestTable_UQ] ON [#TestTable] ([UQ])

INSERT INTO [#TestTable] VALUES (1, 2), (1, 3), (1, 4)

SELECT * FROM [#TestTable]

-- This fails
INSERT INTO [#TestTable] VALUES (2, 1)

hop of those help? For relationship to undestand how to make association you need to pass @user.id. In your button_to pass second id like:
code :
<% @prog.users.each do |user| %>
 <%= button_to "+ Add Programme", :controller => "relationships", :action => "create", :method => "post", prog_id: @prog.id, user_id: user.id %>
<% end %>
def create
 @user = params[user_id]
  @relationship = @user.relationships.build(params[:relationship])
    if @relationship.save
  ....
end

wish helps you It looks like you have discovered a bug in the ARCHIVE engine. The insertion seems to be failing as soon as you try to insert a record with a value for an AUTO_INCREMENT column smaller than the AUTO_INCREMENT property of the table.
This works fine:
code :
CREATE TABLE test_table1 (
  id INT NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (id)
) ENGINE=ARCHIVE AUTO_INCREMENT=123; -- notice the AUTO_INCREMENT value

INSERT INTO test_table1 (id) value (123); -- ok
CREATE TABLE test_table2 (
  id INT NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (id)
) ENGINE=ARCHIVE AUTO_INCREMENT=124; -- notice the AUTO_INCREMENT value

INSERT INTO test_table2 (id) value (123); -- duplicate key

Hope that helps Subversion puts those mine and theirs blocks in your code for a reason. It wants you to handle that merge conflict. If Subversion simply ignored conflicts and just used your code, you could end up committing your code back into the repo, and remove the other developer's work.
I am not sure how TortoiseSVN works, but I know the command line will tell you about a merge conflict as it happens, then give you a choice of what you want to do: Take their code?, Take your code?, Accept their code for conflict?, Accept your code for conflicts?, Postpose resolution, and finally, launch a third party merge tool for the merge.
