可以编写的最简单的可用代码生成器也许就是构建一个静态查找表。
Probably the simplest useful code generator you could write would be one to build static lookup tables.
可以将每个规则都视为在定义所指示的元素之间的映射（查找表）。
You can think of each rule as defining a mapping (look-up table) between elements of the indicated types.
通常，这可以通过使用简单的查找表或从数据库表读取值来实现。
Often, this can be implemented by using a simple lookup table or reading values from a database table.
HASH_LOOKUP，该函数根据源列派生的值来确定查找表的目标列值。

假设我们希望得到这样一个查找表：它返回5到20之间各个数字的平方根。
Let's say you want a lookup table that will return square roots of Numbers between 5 and 20. A simple program can be written to generate such a table like this.
如果在DB 2中建立了查找表来保存字段的值的有限集，那么这对于该字段是必需的。
This was necessary for fields where lookup tables were established in DB2 to hold the limited set of values for that field.

清单1是查找表的示例实现(摘自最近的那篇技巧)，在查找失败时，它可以提供默认值。
Listing 1 is the example implementation (from the most recent tip) of lookup tables that can provide a default value when the item being looked up is not found.
OLTP查询中很少需要选择查找表作为需要相关表上的索引来支持联接的主查询表。
It is rare in an OLTP query for the lookup tables to be selected as the primary query tables requiring an index on the dependent table to support the join.
G：该选项将生成查找表并将其作为静态全局变量，而不是在查找函数内生成以隐藏该表(默认行为)。
G: This option generates the lookup table as a static global variable rather than hiding it by generating it inside the lookup function (the default behavior).
c选项将创建使用const关键字声明的查找表。所有生成的查找表中的内容都是常量—即只读形式。
The -c option creates the lookup tables declared with the const keyword; the contents of all generated lookup tables then are constant-that is, read-only.
问题的解决方案就是忽略复杂的东西，比如查找表，或是寄望memcached服务器来为您处理这个过程。
The solution is to ignore complexities like lookup tables or expecting the memcached server to handle the process for you.
该连接的执行过程包括扫描散列连接中的内表CUSTOMERS，并通过散列连接列的值生成一个查找表。
The join is performed by scanning the inner table of the hash join, CUSTOMERS, and generating a lookup table by hashing the join column values.
然后，它使用SHIP操作符读外表BAD_CREDIT，散列连接列的值，并检查为内表生成的查找表。
IT then reads from the outer table BAD_CREDIT using the SHIP operator, hashing the join column values, and checking in the lookup table generated for the inner table.
如果存在新的标准，那么应该通过映射值，根据一个查找表或一个定义好的模式或算法，将数据映射到那些新的标准上。
If new standards exist, data should be mapped to those new standards through mapping values, against a lookup table, or based on a defined pattern or algorithm.
当将查找（lookup）表与其他较大的分区的表相连接时，通过将查找表也进行分区，可以最大化并行度。
When lookup tables are used in joins with other large partitioned table spaces, you can maximize the parallelism in the join by partitioning the lookup tables as well.
RAND _ LOOKUP，随机查找函数，该函数根据作为查找表中下标的随机数从查找表中选择目标列的值。
RAND_LOOKUP, a random lookup function that selects a value for the destination column from a lookup table based on a random number as the subscript in the lookup table.
当gperf找到某种配置，并且该配置将每个keysig分配到生成的查找表中惟一位置时，将生成一个完美hash函数。
A perfect hash function is produced when gperf finds a configuration that assigns each keysig to a unique location within the generated lookup table.
保存CU名称的另一个目的是为了查找行号表，从而查找该CU中所有函数的行号。
The name of the CU is also stored to find the line number table for locating the line Numbers for all the functions in this CU.
