A table is comprised of fields.
Actually, in a relational database, when two tables have a common field, the relationship between the tables is known as a foreign key constraint. This constraint ensures that values in the common field of one table correspond to values in another table, helping maintain data integrity and enabling queries across related tables.
The SQL command UPDATE can be used to change contents of one database using the contents of another database by joining them on a common key field. You would typically use a query with a join condition between the two tables based on the common key field to update the fields in the target table with values from the source table.
In a table, a field is a column that contains specific information or data about one aspect of the entity being stored in the table. Each field represents a particular attribute or characteristic of the data being stored.
A common field in a database is the "primary key". It is a unique identifier for each record in a database table and is used to uniquely identify each row. It is typically a numerical value or a combination of values that ensures each record is distinct from all others.
In a database, a field that uniquely identifies a particular record in a table is called
a field that is the same as one in another table

A common keyboard shortcut to move to the next field in a table is the "Tab" key. When you press "Tab," the cursor shifts to the next cell or input field, allowing for quick navigation. If you want to move to the previous field, you can use "Shift + Tab." This functionality is widely supported in spreadsheet applications and form interfaces.
It depends on the field's dependencies. If the field has no dependencies then there are no consequences. Data that depends on the table is a dependency, as is code and other tables that depend upon the field.
