When you compute an integral in single variable calculus, you don't do that. You don't cut into little pieces and sum the pieces together.

当计算一个单变量的积分时，你不会这样做的，不会分割出一个个小块，再对这些小块求和。

The optimizer can then compare the input variable values to catalog statistics and compute a better selectivity estimate for predicates.

然后，优化器可以将输入变量的值与编目统计进行比较，并为谓词计算出一个更好的选择估计。
