    <p>I'm working with SQL Server 2012 </p> <p>I have two tables, <code>Person</code> and <code>Couple</code>, <code>Person</code> has a foreign key from <code>Couple</code> and <code>Couple</code> has foreign key from 'Person'.</p> <p>When I try to insert data into each one, an error occurs because each table has FK from the other table, and both are empty initially.</p> <pre><code>CREATE TABLE [dbo].[Couple]( [CoupleId] [int] IDENTITY(1,1) NOT NULL, [HusbandPersonId] [int] NOT NULL, [WifePersonId] [int] NOT NULL, [StartDate] [date] NOT NULL, [EndDate] [date] NOT NULL, CONSTRAINT [PK_Couple] PRIMARY KEY CLUSTERED ( [CoupleId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] CREATE TABLE [dbo].[Person]( [PersonId] [int] IDENTITY(1,1) NOT NULL, [ChildOfCoupleId] [int] NOT NULL, [CityOfBirth] [int] NOT NULL, [CityOfPermanentResidence] [int] NOT NULL, [CityOfCurrentResidence] [int] NOT NULL, [FirstName] [varchar](20) NOT NULL, [LastName] [varchar](20) NOT NULL, [BirthDate] [date] NOT NULL, [DeathDate] [date] NOT NULL, [IsMale] [bit] NOT NULL, CONSTRAINT [PK_Person] PRIMARY KEY CLUSTERED ( [PersonId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY ALTER TABLE [dbo].[Couple] WITH CHECK ADD CONSTRAINT [FK_Couple_Person] FOREIGN KEY([HusbandPersonId]) REFERENCES [dbo].[Person] ([PersonId]) GO ALTER TABLE [dbo].[Couple] CHECK CONSTRAINT [FK_Couple_Person] GO ALTER TABLE [dbo].[Couple] WITH CHECK ADD CONSTRAINT [FK_Couple_Person1] FOREIGN KEY([WifePersonId]) REFERENCES [dbo].[Person] ([PersonId]) GO ALTER TABLE [dbo].[Couple] CHECK CONSTRAINT [FK_Couple_Person1] GO ALTER TABLE [dbo].[Person] WITH CHECK ADD CONSTRAINT [FK_Person_Couple] FOREIGN KEY([ChildOfCoupleId]) REFERENCES [dbo].[Couple] ([CoupleId]) GO ALTER TABLE [dbo].[Person] CHECK CONSTRAINT [FK_Person_Couple] GO </code></pre> <p>How to solve this ?</p>

    3. COSome DBMS allow you to define constraints as *deferred* so that they are evaluated when you commit the transaction, not when you run the `insert`. Not sure if SQL Server 2012 has such a feature though.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
