如果联接键是一个复合键,那么必须使用PRIOR运算符为每个键所在的列加上前缀。
If the join key is a composite key, each key column must be prefixed with the PRIOR operator.
AlignAssignments()中的第一个for循环判断其中的赋值运算符应当对齐的列。
The first for loop in AlignAssignments() determines the column in which the assignment operators should be aligned.
为了实现这个目标,我们将调用observer方法(使用双点运算符)获取address列中的结构化类型值的城市属性。(清单2)。
To do that, we will invoke the observer method (using the double-dot operator) for the city attribute of the structured type value in the ADDRESS column (Listing 2).
并且具有下列PL/SQL SQL语句,可以使用它们在列 flag1和flag2(均为BOOLEAN数据类型)上进行运算
and we have the following PL/SQL SQL statements that manipulate with columns flag1 and flag2 (both of BOOLEAN data type)
该算法每步运算可生成一列元素而不是一个元素,因而减少了运算次数,加快了生成速度。
Its each operational step produces a string of elements instead of one element. Hence the algorithm reduces the time of operation, and accelerates the speed of generation.
并且这些体系所使用散列算法在实质上都是串行的,因而待加密数据越长,加密运算时光越长。
Those hash algorithms are essentially serialized, so the longer the length of the source file is, the longer the hash operation takes.
安全散列算法的运算位数与运算的轮数较多,用硬件实现需耗费大量的资源。
Duo to the many of the bits and times of the SHA, it need a lot of resources with hardware.
该算法利用多项式带余除法的相关推论,通过矩阵的列变换来求解关键方程,这样可以快速地得到商式和余式,从而可以减少迭代运算的次数。
The proposed algorithm use the related deduction of division with reminder of polynomials and the key equation is solved by column transformation of matrix.
说明如何在运算符只带一个参数的情况下在查询中包含多列。
Describes how to include more than one column in a query where the operator takes only a single argument.
在多行或者多列进行运算时,并且人运算的公式相似时,相对引用的使用可以节省你大量的时间。
Relative references can save you time when you're repeating the same type of calculation across multiple rows or columns.
在查询中使用列的任何位置,都还可使用由列、文本、运算符和函数的任意组合组成的表达式。
Wherever you use a column in a query, you can also use an expression that can consist of any combination of columns, literals, operators, and functions.
接下来的大序列、序列模式等都是通过矩阵的列向量对应元素的相乘运算和简单的加法运算而得到。
Then, large sequence and sequential patterns are all out pass the vector of matrix multiplication operator corresponding to the elements and simple addition operations have been.
