Column - Name of the column in question. The above query shows all tables that have more than one index with the same leading column. These indexes can cause queries to use an inappropriate indexes; in other words, Oracle will use the index that was created most recently if two indexes are of equal ranking.
Some different types of gases are argon, carbon dioxide, hydrogen,  helium, oxygen, nitrogen, nitrous oxide, propane and propylene. Carbon dioxide is used for fermentation, â¦ and oxygen and nitrogen  are what makes up the Earth's atmosphere.1 person found this useful. Jan C.tmosphere contains roughly (by volume) 78.09% nitrogen, 20.95%oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.
The elements that are gases at room temperature include hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, krâ¦ypton, xenon and radon. We also know that the halogens fluorine, chlorine and bromine are gases at room temperature (20Â°C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases. LAUGH OUT LOUD.
