In this tutorial, you have learned how to use a simple form of the SQLite SELECT statement to query data from a single table. You will also see the UPDATE in action via several examples. In Example 4, I’ll show how to nest a for-loop into another for-loop. But it does omit some features while at the same time adding a few features of its own. This tutorial shows you how to use SQLite UPDATE statement to update existing data in a table. for-loops are often used in nested loops. So try to avoid using the asterisk (*) as a good habit when you use the SELECT statement. SQLite understands most of the standard SQL language. If someone adds more columns, your application may work but it gets more data than needed, which creates more I/O overhead between the database and application. What if someone removes a column, your application would not be working properly, because it assumes that there are three columns returned and the logic to process those three columns would be broken. Includes update to the most recent SQLite (3.35.4) and brings back independent SQLite library file to allow user manual updates if necessary. Suppose, a table has 3 columns, and you use the asterisk (*) to retrieve the data from all three columns. 3.3.3 released Rather small, yet important bugfix release. Another import or export format, another table data populating strategy, another SQLite database format, SQL code formatter, code highlighter, table cell value representation renderer - all of these can be exteded with plugins. For example another scripting language can be added with plugin. When you develop an application, you should control what SQLite returns to your application. SQLiteStudio supports plugins of several categories. You should use the asterisk (*) for the testing purpose only, not in the real application development. Exercise 5: Display numbers from a list using loop. Exercise 4: Write a program to print multiplication table of a given number. Exercise 3: Calculate the sum of all numbers from 1 to a given number.
