mysql – SQLite中的null-safe相等运算符<=>的等价物是什么？

的等价物是什么？' />

我需要确定MySQL中<=> operator的SQLite的等价物.

任何的想法？

解决方法:

The IS and IS NOT operators work like = and != except when one or both
of the operands are NULL. In this case, if both operands are NULL,
then the IS operator evaluates to 1 (true) and the IS NOT operator
evaluates to 0 (false)
