您可以通过使用“删除”查询删除表中的所有行。

You can delete all rows in a table by using a delete query.

youdao

如果没有包括任何where子句，则删除表中的所有行。

If no WHERE clause is included, all rows in the table are deleted.

但是，一般地，您不希望删除表中的所有行；而是有选择地删除行。

In general, however, you don't want to delete all rows from a table; instead, you'll selectively delete rows.
