+Table: Triangle
+
++-------------+------+
+| Column Name | Type |
++-------------+------+
+| x           | int  |
+| y           | int  |
+| z           | int  |
++-------------+------+
+In SQL, (x, y, z) is the primary key column for this table.
+Each row of this table contains the lengths of three line segments.
+ 
+
+Report for every three line segments whether they can form a triangle.
+
+Return the result table in any order.
+
+The result format is in the following example.
+
+ 
+
+Example 1:
+
+Input: 
+Triangle table:
++----+----+----+
+| x  | y  | z  |
++----+----+----+
+| 13 | 15 | 30 |
+| 10 | 20 | 15 |
++----+----+----+
+Output: 
++----+----+----+----------+
+| x  | y  | z  | triangle |
++----+----+----+----------+
+| 13 | 15 | 30 | No       |
+| 10 | 20 | 15 | Yes      |
++----+----+----+----------+

 SELECT x,y,z,(
     CASE
         WHEN x+y>z AND x+z>y AND y+z>x THEN 'Yes'
