Relational data is " flat " - that is , organized in the form of a two - dimensional array of rows and columns 关系数据是“平面的” ,即它是以具有行与列的二维数组的形式组织的。
For example , you can access the first element of the second row of the two - dimensional array by specifying indexes 例如,指定索引( 1 , 0 )可以访问二维数组第二行的第一个元素。
Up until now , we haven t dealt with two - dimensional arrays ; however , as you can see below , the syntax is quite simple 目前,我们还没有处理过二维数组;但是,在下面可以看到,语法非常简单。
Create matrix array builds a two - dimensional array that contains two columns and three rows , and then displays it in a list box 创建矩阵数组生成一个包含两列和三行的二维数组,然后在列表框中显示。
The following code shows a call in which a two - dimensional array is passed to a procedure that expects a one - dimensional array 下面的代码演示一个调用,其中,二维数组被传递到需要一维数组的过程中。
