    <p>I'll try to take a different approach and give a comprehensive answer, perhaps it will be more clarifying. <strong>The function will take any variable that fits the exact type of the parameter it was declared with</strong>. A basic array in C++ is simply a constant pointer (Points to the beginning, holds the space size for the rest). Storing an array of arrays by memory allocation using pointers is not exactly the same as a 2D array generated by C++ (The assembly code generated for <code>datatype arrays[const][const]</code> and for <code>**arrays = new datatype[const]</code>is different). This is important to know because your can draw the <strong>distinction between a pointer to a pointer and a 2D C++ generated array</strong>. </p> <p>To keep things simple, <strong>treat your parameter exactly as it is: a pointer to a pointer</strong>. If that is what you are passing to the function, which is your case, then you are passing the right variable to the right parameter. <strong>The way you handle that parameter within the function will be what determines if you are treating it as a 2D array or not</strong>.</p> <p>I'm answering this way because there seems to be some doubt on why a pointer to a pointer is treated as a 2D array. If that is the case, you are right to doubt. The <strong>2D array is just an interpretation</strong> of what the variable is holding, but the <strong>variable is still a pointer to a pointer</strong> and you give it the same treatment as with other pointer variables (Memory allocation and deallocation, passing as parameter, handling, etc...).</p> <p>As for replacing it with structs (classes) and whatnot: I believe you are doing things that way in order to <strong>better comprehend memory allocation and pointing</strong> by creating dynamic multidimensional arrays, using C++ simply as the mean. If that is the case, then I believe my answer will fit your needs well. Otherwise, there are alternatives which are better abstracted and that will automatically handle memory allocation (For C++, search for STL containers). By doing it your way, you increase your understanding of what goes on "behind the scenes", if you will. It is knowledge of <strong>greater importance in computational science</strong> than in modern or future programmatic usage. </p> <p>Hopefully the answer was such that you will be able to handle similar situations by understanding what is happening, which is generally the true cause for incorrect syntax in these cases. English is not my native language; I apologize in advance for possible semantic misuses.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
