+## array_exists
+
+<version since="2.0">
+
+array_exists(lambda,array1,array2....)
+array_exists(array1)
+
+</version>
+
+### description
+
+使用一个可选lambda表达式作为输入参数，对其他的输入ARRAY参数的内部数据做对应表达式计算。当计算返回非0时，返回1；否则返回0。
+在lambda表达式中输入的参数为1个或多个，必须和后面的输入array列数量一致。在lambda中可以执行合法的标量函数，不支持聚合函数等。
+在没有使用lambda作为参数时，array1作为计算结果。
+
+```
+array_exists(x->x, array1);
+array_exists(x->(x%2 = 0), array1);
+array_exists(x->(abs(x)-1), array1);
+array_exists((x,y)->(x = y), array1, array2);
+array_exists(array1);
+```
+
+### example
+
+```shell
+
+mysql [test]>select *, array_exists(x->x>1,[1,2,3]) from array_test2 order by
id;
++------+-----------------+-------------------------+-----------------------------------------------+
+| id | c_array1 | c_array2 | array_exists([x] -> x(0)
> 1, ARRAY(1, 2, 3)) |
