Structured Query Language (SQL) is used I think

Answer 2

In SQL, the TRUNCATE TABLE statement is a [Data Definition Language] (DDL) operation that marks the extents of a table for deallocation (empty for reuse). The result of this operation quickly removes all data from a table, typically bypassing a number of integrity enforcing mechanisms. It was officially introduced in the SQL:2008 standard.
