Antidiuretic hormone (ADH, vasopressin) is produced by the supraoptic and paraventricular nuclei of the hypothalamus and travels in the axons through the pituitary stalk to the posterior pituitary gland.
What is a foreign key in SQL Server? A foreign key is a way to enforce referential integrity within your SQL Server database. A foreign key means that values in one table must also appear in another table. The referenced table is called the parent table while the table with the foreign key is called the child table.
If a source table has a foreign key constraint note that the SQL Server Import and Export Wizard does not load tables a specific order for constraints, and it is possible that a table containing a foreign key will get loaded before a table containing a referenced primary key, which will cause a foreign key constraint failure.
