SQLite: drop table

Dropping a table only if it exists

In order to suppress error messages, SQLite supports the drop table if exists clause which only tries to drop a table if it in fact does exist:

create table tq84_table (a, b, c);

drop table if exists tq84_table;

drop table if exists tq84_table;
