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.
Many inorganic and organic compounds with four or fewer nonhydrogen atoms are also gases at room temperature and pressure. All gaseous substances are characterized by weak interactions between the constituent molecules or atoms.xcept for hydrogen, the elements that occur naturally as gases are on the right side of the periodic table. Of these, all the noble gases (group 18) are monatomic gases, whereas the other gaseous elements are diatomic molecules (H 2, N 2, O 2, F 2, and Cl 2).
