Generate Tables Using sys.dummy
sys.dummy is a virtual table that the generates with a specific number of rows. This table is a handy tool to quickly create tables for testing without scripting extensive DDL commands.
When you execute sys.dummy, the database creates a table with a single column, which is automatically populated with incremental integers.
sys.dummy follows similar rules to a table reference. The command must specify a positive integer that represents the number of rows for the command to generate in the table.
In this syntax block, the {N} parameter represents the number of rows for sys.dummy to generate. Do not specify curly brackets with this parameter in queries.
