比如：有如下一张设备电子围栏位置坐标的表（tb_equ_point）。
equ_name:设备电子围栏名称
point_id:点位坐标id
point_x:点位x坐标
point_y:点位y坐标。

现在想把数据按名称合并，一组x坐标和y坐标放在一起，用 “，” 隔开，x,y的顺序要对应。
效果如下图：
sql如下：
SELECTequ_name,LISTAGG ( POINT_X, ',' ) WITHIN GROUP ( ORDER BY point_id ) AS POINT_X,LISTAGG ( POINT_Y, ',' ) WITHIN GROUP ( ORDER BY point_id ) AS POINT_Y
FROMtb_equ_point
GROUP BYequ_name解析：
Oracle的LISTAGG函数将多个结果合并到一起，示例如下：
SELECT name, LISTAGG(x, ',') WITHIN GROUP (ORDER BY x) AS x_list, LISTAGG(y, ',') WITHIN GROUP (ORDER BY y) AS y_list
FROM table_name
GROUP BY name
其中，table_name是你的表名，x_list和y_list分别是按name分组后合并的x和y结果。如果需要在结果中添加分隔符，可以在LISTAGG函数的第一个参数中指定。例如，如果想在结果中使用“|”作为分隔符，可以将函数改为：
LISTAGG(x, '|') WITHIN GROUP (ORDER BY x) AS x_list
同样的，也可以使用其他聚合函数，如MAX、MIN、AVG等。
注：合并的字段，x,y要顺序对应的话，要有一个统一的标识point_id。
