Welcome to the first part of what should be the final two articles in our series on working with hashes and lists in Perl. This makes our eleventh article in the series and in it, we will wrap up the intermediate ways of working with hashes and lists. We'll learn to add rows and columns to a two-dimensional list, replace them, create multi-dimensional lists, and write hashes and files to lists, then open and read from those same files over the next two articles.

Thanks for stopping by to read my tenth installment on working with hashes and lists in Perl. In our previous article we learned how to find out if a hash holds a specific value, does not hold a specific value, or holds any value whatsoever. We further learned to create our first two-dimensional array and then worked to better understand how exactly a two-dimensional array works. Which is where we pick up in this article.

Welcome to the ninth installment in our look at working with hashes and lists in Perl. In our previous article we learned how to add records to a hash, replace them, and delete the values inside of them. In this article we will learn how to check whether records reside within our hashes, write the data within a hash to a file, and create multidimensional lists.

Welcome to the eighth episode in our series on Perl Lists and Hashes. In this article we will discuss how to add a record to a hash, as well as how to remove a record from one. We will also cover how to check to see if a record already exists in our hash, how to write the data contained in one to a file, and quite possibly go over the basics of multidimensional lists.

Thanks for stopping by for this seventh part in the series on Perl Lists and Hashes. Here we will discuss working with a new way to store data known as a Hash. We'll cover the basics, such as how to create them, and how to locate data within them. You'll learn to add records, remove records, and much more. If there is time, we will also cover multidimensional lists.

Welcome to the sixth part of our series on Perl Lists. Here we will cover the remaining four List::Util subroutines: min(list), minstr(list), shuffle(list), and sum(list). We'll learn how to manipulate lists using these subroutine in various intended and unintended ways.

In this fifth part of our series on Lists, we will cover the List::Util module, which gives us seven handy-dandy subroutines with which to manipulate our lists. If we have time, we'll also cover multi-dimensional lists in more depth (we briefly covered them in an earlier article).

In this fourth part of our series on Lists, we will start off with the split() function and hopefully end by covering hashes. In our last article, we covered the splice() function, which we used to add, remove, and replace elements in a list. We then used it to create variables and arrays. We also worked with some operators to repeat a list and to create sequential lists.

In this conclusion to a four-part series on Perl and DBI, you will learn about SQL queries and DBI, using Perl and DBI with CGI, and more. This article is excerpted from chapter 15 of the book Beginning Perl (Apress; ISBN: 159059391X).

We left off covering the splice() function, which can be used for adding and removing elements from a list. We also spoke about four other functions: pop(), push(), shift(), and unshift(), which are all similar to the splice() function, just not as flexible. In this article, we'll start out by discussing the splice() function in more detail, and learning how to remove more than one element in a list.

In this third part of a four-part series on Perl and DBI, you will learn about using SELECT queries to get information from databases. This article is excerpted from chapter 15 of the book Beginning Perl (Apress; ISBN: 159059391X).

In our last article we talked about lists, going somewhat in-depth on their capabilities. We talked about creating them, printing from them, and even used a slicing technique to add and remove from our lists. In this article we will start off looking at more traditional ways to add and remove from a list, and move on from there.

In this second part of a four-part series on Perl and the DBI, you'll learn how to create a database and how to use a collection of very important commands. This article is excerpted from chapter 15 of the book Beginning Perl by James Lee (Apress; ISBN: 159059391X).

People love lists. Everywhere you look you see them. On magazines, on television. They're everywhere; you can't escape. In this article and the ones that follow, I am going to teach you to blend in with the crowd by using Perl to create lists, multidimensional lists, and hashes, and furthermore, I'll show you how to manipulate each of them.

Databases are a mission-critical part of any company's resources. If you program in Perl, you'll want to learn about the DBI, which can help you connect to many popular databases. This article, the first part of a series, is excerpted from chapter 15 of the book Beginning Perl (Apress; ISBN: 159059391X).
