Table Alias

At the top of the form, specify the base table alias (Currently, the base table alias is display-only.)

In the grid, specify the alias of the table that is being joined.

An alias is a unique, valid SQL identifier for a table. It is used to reference the table in join specifications and in generated SQL. An alias (usually a shorter version of the table name) can make a SQL statement shorter and easier to read. Aliases are also useful when working with multiple instances of the same table when you need to refer to one instance or the other.
