在满足筛选器条件的每个行中,数据库服务器将对键应用哈希函数,并探测哈希表以查找匹配的键值。
For each row that satisfies the filter condition, the database server applies hash function to the key and proves the hash table to find a match.
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.
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.
HASH_LOOKUP,该函数根据源列派生的值来确定查找表的目标列值。
HASH_LOOKUP, a function that determines the destination column value from a lookup table according to a value derived from a source column.
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).
这意味着,如果SQL稍微有点复杂,并且要查询一个表来查找多个结果,那么该函数会在所呈现的xhtml表中创建一个新行。
This means that if your SQL were a bit more complicated and queried a table for multiple results, it would create a new line in the rendered XHTML table.
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.
该函数使用查找表来确定目标列值。
Lookup, a function that USES a lookup table to determine the destination column value.
如果不提供查找表,该函数将未修改的源值复制到目标中。
If you do not provide a lookup table, the vi copies the source value to the destination unmodified.
如果不提供查找表,该函数将源像素值不修改复制到目标像素。
If you do not provide a lookup table, the vi copies the source value to the destination unmodified.
第三步利用MODIS的通道响应函数,把查找表光谱数据变换成MODIS波段反射率。
The third step is changing the look-up table data into MODIS spectral data using MODIS channel response function.
为了实现对星对信息表的快速查找,提出了一种将星对信息表拟合成曲线函数实现快速角距匹配的方法。
A speedy match of angular distance method was formulated by curve fitting the table of star pair for realizing rapid match in star pair information catalogue.
换句话说,这不是一个通用的方式图每个像素通过一个函数,它只是一种方法来动态地建立查找表,而不是通过预先建立的一个。
In other words, it's not a general-purpose way to map each pixel through a function, it's just a way to dynamically built the lookup table, instead of passing in a pre-built one.
