IF/THEN/ELSE逻辑是搞清楚如何使用WHERE 子句谓词的良好基础，因此在DB2地址空间中行能够被快速拒绝。
IF/THEN/ELSE logic is fertile ground for figuring out how to use WHERE clause predicates so rows can be rejected sooner in DB2's address space.
sql表函数的使用使您可以将过程性逻辑放入到查询的from子句中。
The usage of SQL Table Functions allows you to push procedural logic into the FROM clause of a query.
这些STAGE3谓词，特别是拒绝大部分行的那些，通常是不使用WHERE 子句的旧有VSAM逻辑的结果。
These STAGE 3 predicates, especially those that reject a majority of the rows, are usually the result of old VSAM logic that did not utilize a WHERE clause.
由于该子句的逻辑跟前一场景中给出的逻辑非常类似，我们这里就不再复习它了。
Since the logic of this clause is very similar to the logic presented in previous scenarios, we won't review it again here.
直接的语句执行方法包括：sql语句中在where子句之后剥离数据的附加逻辑。
