Unformatted text preview: Geometry Examples The third triplet indicates that the second subelement line string is made up of a circular arc with ordinates starting at offset 5. The end point of this line string is determined by the starting offset of the next element or the current length of the SD070RDINATES array, if this is the last element. I SDO_ORDINATES = (6,10, 10,1, 14,10, 10,14, 6,10). Example 2—7 shows a SQL statement that inserts the geometry illustrated in Figure 2—5 into the database.
