SQL Window

Append Mode: Each time a SQL statement is executed, the new result set is appended to the previous one.
Overwrite Mode: Each time a SQL statement is executed, the new result set overwrites the previous one.

DAS allows you to easily run various SQL statements in a graphical SQL window and to perform operations on databases, such as adding, deleting, editing, and viewing a database.
