USING Clause
You can use the USING clause to declare explicit names for the violations table and for the diagnostics table.
If you omit the USING clause, the database server assigns names
to the violation table and the diagnostics table. The system-assigned
name of the violations table consists of the name of the target table
followed by the string _vio
. The name that the database
server assigns to the diagnostics table consists of the name of the
target table followed by the string _dia
.
If you omit the USING clause, the maximum length of the name of the target table is 124 bytes.
