TSQL Interview Questions: Table

A table is a set of data elements (values) that is organized using a model of vertical columns (which are identified by their name) and horizontal rows, the cell being the unit where a row and column intersect. A table has a specified number of columns, but can have any number of rows [citation needed]. Each row is identified by the values appearing in a particular column subset which has been identified as a unique key index.
