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.
2) Import data from specific fields from the source file to create table 2 Invoices BUT also include at least one field associated with data from table 1 as the Foreign key and then use that field to to connect to the Primary key of table 1 Customers.rders is the child. I want to link Orders to Customers so I created a foreign key field in the Orders table called CustomerID and linked it to the Customers primary key. All great so far. But CustomerID in the Orders Table is empty of the primary key data for a relationship.
