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. Suppose, a table has 3 columns, and you use the asterisk (*) to retrieve the data from all three columns. When you develop an application, you should control what SQLite returns to your application. You should use the asterisk (*) for the testing purpose only, not in the real application development. To avoid this, you can use the asterisk (*), which is the shorthand for all columns of the table as follows: SELECT * FROM tracks Code language: SQL (Structured Query Language) ( sql ) To get data from all columns, you specify the columns of the tracks table in the SELECT clause as follows: SELECTįor a table with many columns, the query would be so long that time-consuming to type. You specify a list column names, which you want to get data, in the SELECT clause and the tracks table in the FROM clause. Tracks Code language: SQL (Structured Query Language) ( sql ) To get data from the tracks table such as trackid, track name, composer, and unit price, you use the following statement: SELECT The tracks table contains columns and rows. Let’s take a look at the tracks table in the sample database. You use the semicolon ( ) to terminate the statement. Second, specify a column or a list of comma-separated columns in the SELECT clause.We will discuss it in the subsequent tutorial. Notice that you can have more than one table in the FROM clause. First, specify the table where you want to get data from in the FROM clause.SELECT column_listįROM table Code language: SQL (Structured Query Language) ( sql )Įven though the SELECT clause appears before the FROM clause, SQLite evaluates the FROM clause first and then the SELECT clause, therefore: In this tutorial, we are going to focus on the simplest form of the SELECT statement that allows you to query data from a single table. Use GROUP BY to get the group rows into groups and apply aggregate function for each group.Use INNER JOIN or LEFT JOIN to query data from multiple tables using join.Use LIMIT OFFSET clauses to constrain the number of rows returned.Use WHERE clause to filter rows in the result set. Use DISTINCT clause to query unique rows in a table.Use ORDER BY clause to sort the result set.To help easier to understand each part, we will break the SELECT statement into multiple easy-to-understand tutorials. The SELECT statement is the most complex statement in SQLite. ORDER BY column LIMIT count OFFSET offset GROUP BY column HAVING group_filter Code language: SQL (Structured Query Language) ( sql ) The syntax of the SELECT statement is as follows: SELECT DISTINCT column_list We often use the SELECT statement to query data from one or more table. Try It Querying data from a table using the SELECT statement You can use multiple expressions in the SELECT statement as follows: SELECT 10 / 5,Ģ * 4 Code language: SQL (Structured Query Language) ( sql ) You can use the SELECT statement to perform a simple calculation as follows: SELECT 1 + 1 Code language: SQL (Structured Query Language) ( sql ) The SQLite SELECT statement provides all features of the SELECT statement in SQL standard. The SELECT statement is one of the most commonly used statements in SQL. Summary: in this tutorial, you will learn how to use SQLite SELECT statement to query data from a single table.

Generally, body size increases with latitude. There is considerable variation in size among platypus populations. The white spots on the fur under its eyes make it look like its eyes are open underwater, but they’re not. On land, the platypus has a reptilian gait because its legs are on the sides of the body, rather than underneath. Other interesting characteristics include extra bones in the shoulder girdle, which is absent in other mammals. While most other mammals have so-called live young, platypuses (along with echidnas) lay eggs, incubate them, and nurse their young. Of course, its major claim to fame is being an egg-laying mammal, or monotreme. Interestingly, freshly hatched platypuses have molar-like “milk teeth," but these are shed around the time they leave the nesting burrow. These pads are replaced continuously throughout its lifetime. They (and their relatives the echidnas) don’t have teeth, but instead grind their food between mouth pads made of keratin. Platypuses stow their prey in cheek pouches, and swim to the surface to eat. Moving its head back and forth, it can find prey nearby and swiftly move in for the kill. Additionally, about 40,000 electroreceptors help them find the direction and distance of prey (its eyes and ears are closed while it’s underwater) by detecting electrical impulses generated by living creatures. This strange-looking snout is laden with “pushrods” that respond to stimuli like touch, pressure, sound waves, and motion. It is dark colored, nearly black in contrast to its chocolate-colored coat. Its signature “duck bill” is actually soft and pliable, not hard like a duck’s bill at all. Its rear feet serve as rudders and brakes. Its plump tail serves as a stabilizer during swimming and stores extra fat for energy. While lumbering somewhat awkwardly on land to protect the webbing on its feet, they are sleek missiles in the water. Those big webbed feet help propel them through the water, and the claws make digging burrows a breeze. Mostly brown on its body, there’s a flash of white fur beneath its eyes, and its belly is lighter in color, too. Long guard hairs protect the dense fur underneath, which stays dry even after a platypus has been in the water for hours. Platypus fur is waterproof and traps an insulating layer of air to keep its body temperature stable, even in cold water. Their dense fur makes fine insulation, both in the water and out. While their range is just one small area of the world, they weather many climate extremes (and fresh water sources) from toasty plateaus and rainforests, to the chilly mountainous regions of Tasmania and the Australian Alps. At a glance, it looks like a hodgepodge of animal pieces stitched together: a paddle-shaped tail from an otter, a sleek body covered in dense, chestnut-colored fur like a mole, a wide, flat duck-like bill attached in front of its little round eyes, and big webbed feet like a pelican.Īll these characteristics come in handy for its freshwater lifestyle-that bizarre looking bill is laden with thousands of receptors that help a platypusl navigate the murky depths and detect tiny movements of potential food like shellfish or insects. The platypus is as fascinating on the inside as it is on the outside! Among Australia’s most iconic wildlife, this semi-aquatic, egg-laying species is also one of the few venomous mammals.

Dixie has the ability to spin her ponytail into a propeller and slowly descend through the air, with an initial boost in height at the start, allowing her and Donkey Kong to fly up out-of-reach platforms or items. Along with Diddy Kong, who returns with his barrel jet pack for crossing large gaps, two additional characters are added Dixie Kong and Cranky Kong. Like the previous game, players primarily control Donkey Kong who is assisted by a companion, who either provide additional abilities to Donkey Kong, or can be controlled individually by a second player. Controls are similar to the previous game, with the addition of being able to pluck items from the ground and pick up and throw stunned enemies, and various controllers can be used with customizable controls. The game continues on from the side-scrolling platform gameplay of the Donkey Kong Country series and sees Donkey Kong and his friends traveling through seven different islands in order to defeat the Snowmads. Mario vs.Player one controls Donkey Kong, while the second player controls Diddy Kong or one of the other two Kongs, in a standard level.Tawks the Parrot (Nintendo Switch version only).However, the player cannot have an assist Kong, except as a second player in the multiplayer mode. He also has five hearts instead of two hearts. When playing as him, the player can stay submerged for as long as they want as well as stand on spikes without being hurt. Unlike the other playable Kongs, Funky can hover in midair on his surf board. Funky Mode marks the first time in a Donkey Kong Country game that Funky Kong is playable. The Kongs watch and rejoice as the breeze of the flowers flutter around the island, melting all of the ice and snow, restoring Donkey Kong Island back to its original state and ending the current adventure.įunky Mode, exclusive to the Nintendo Switch version of Donkey Kong Country: Tropical Freeze, allows you to play as Funky Kong. Donkey Kong then notices the horn that was used to freeze the island, which he grabs and blows into, producing a wave of flowers that carries the him and the rest of the heroes to the bottom of the island. The primates wander out of the remains of the ship and look out from the mountainside to see the end of Lord Fredrik's fall, which he slams into the remaining Snowmad ships, defeating them. After a long battle, the Kongs deliver the final punch to Lord Fredrik, which sends him flying out through the entirety of the Snowmad’s galleon, splitting it in half, causing it to fall. He challenges the primates to a final battle deep in the blistering core of the volcano. The heroes make their way up the frozen island until they encounter the leader of the Snowmads, Lord Fredrik, The Snowmad King. Afterwards, the warship of the fleet stations itself where the Volcano is and he Snowmads seize Donkey Kong Island for their own, turning it into a frozen region which only they can inhabit.Īfter landing on the Lost Mangroves island and traversing across five islands, with each posing its own threats, as well as treasures, the Kongs finally return to the Donkey Kong Island. The primates are then blown away from the island by the dragon's intense winds. The Ice Dragon from earlier flies toward Donkey Kong Island, freezing the sea below it. He turns away with an angry look on his face and he and the other Kongs exit the house. Just as he is about to blow the candles out, Donkey Kong notices a mysterious snowflake appear and put out the candle on his birthday cake. Some Tucks bring him a horn which he blows, creating a large amount of wind, as well as an Ice Dragon. Far away from the island, a Pointy Tuck locates the balloon and then spots the tree house and relays info to their silhouetted leader who nods. The story begins with a party at Donkey Kong and Diddy Kong's Treehouse, where the Kongs are celebrating DK's birthday as one of the balloons flies out of the treehouse and over the sea, where a fleet of Snowmad ships are stationed.

The charge that an atom acquires when it becomes an ion is related to the structure of the periodic table. This is also why ionic compounds have every high melting and boiling points.Ĭlick here to go back to the Science menu.\): Predicting Ionic Charges. The attractive forces are very strong in every direction that it takes a lot of energy to break them apart. This ions are regularly arranged in what is known as a lattice. In ionic compounds (compounds formed through ionic bonding), the strong attractive forces between the positive and negative ions result in the formation of a giant ionic structure. Describe the lattice structure of ionic compounds as a regular arrangement of alternating positive and negative ions, exemplified by the sodium chloride structure.Magnesium lost two electrons, so has a 2 charge and oxygen gained two electrons so has -2 charge. Now the configuration of magnesium is 2,8 and that of oxygen is 2,8. The quicker reaction is magnesium giving out the two electrons to oxygen. Oxygen needs to gain two electrons or give out 6 electrons. In order to be stable magnesium either needs to lose the 2 electrons or get 6 electrons. Magnesium has configuration 2,8,2 and oxygen has configuration 2,6. In the chemical bond created between metals and non-metals are always ionic because the metal (Sodium) becomes a positive ion and the non-metal (Chlorine) becomes a negative ion.Īnother example of ionic bonding bonding is the one between the metal Magnesium and the non-metal Oxygen. The above is an example of an ionic bond, where, oppositely charged ions are attracted. Explain the formation of ionic bonds between metallic and non-metallic elements.(The new compound formed is sodium chloride). Chlorine gained one electron, so it gained an extra negative charge, making it a negative (-1) Chlorine ion. Since sodium lost a negatively charged particle, it’s overall charge becomes positive, making it a positive ( 1) sodium ion. Both have full outer shells and so have become stable. This is reflected by decreasing half-lives for nuclei heavier than uranium. Now the configuration of Sodium will be 2,8 and the configuration of Chlorine will be 2,8,8. As the nuclear charge increases to large values, nuclei become more unstable. So sodium will have to lose it’s outer electron to chlorine. In order to make them both stable, sodium needs to lose 1 electron and Chlorine needs to gain 1 electron. Let’s take the electronic configurations of metal ‘Na’ Sodium and the non-metal ‘Cl’ Chlorine.īoth elements are not stable. The elements in group 1 and 2 are metals and the elements in group 7 are non-metals. The block of elements in the yellow colour above are not considered part of any groups here). (Note that the columns in the periodic table are called groups.
