This is equivalent to the expression(min<= expr AND expr<= max) if all the arguments are of the same type.
它等价于表达式(min<=exprANDexpr<=max)，只要所有的参数均是相同的类型。

If expr includes a function, it can be either built-in or user-defined, but not another domain aggregate or SQL aggregate function.

In the following example, if expr evaluates to"Bananas", the program matches the value with case"Bananas" and executes the associated statement.
下面的例子中，如果expr计算为"Bananas"，程序就会匹配值为"Bananas"的case然后执行相关语句。

For expr op{ALL|ANY|SOME}(subquery), expr must be a scalar value and the subquery must be a column subquery; it cannot return multiple-column rows.
Op{ALL|ANY|SOME}(subquery)，expr必须是标度值，子查询必须是列子查询，不能返回多列行。

The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals.
