将强制转换语法从PostgreSQL转换为配置单元

以下语法来自更大的Vertica查询（postgreSQL）。是否可以将此语法转换为配置单元？操作员是一致的。如果是，怎么做

当前错误为： 失败：ParseException行22:19无法识别表达式规范中“|”强制转换“（”附近的输入

 ST_GeomFromText('POLYGON((' || 
    CAST(TRUNC(request_lng / {{zoom_factor}},2) AS numeric) * {{zoom_factor}} + sign(request_lng)*(.01 * {{zoom_factor}})
    || ' ' ||
    CAST(TRUNC(request_lat / ({{zoom_factor}} * {{stretch_factor}}),2) AS numeric) * ({{zoom_factor}}*{{stretch_factor}}) + sign(request_lat)*(.01 * {{zoom_factor}} * {{stretch_factor}})
    || ', ' ||
    CAST(TRUNC(request_lng / {{zoom_factor}},2) AS numeric) * {{zoom_factor}} + sign(request_lng)*(.01 * {{zoom_factor}})
    || ' ' ||
    CAST(TRUNC(request_lat / ({{zoom_factor}} * {{stretch_factor}}),2) AS numeric) * ({{zoom_factor}}*{{stretch_factor}}) 
    || ', ' ||
    CAST(TRUNC(request_lng / {{zoom_factor}},2) AS numeric) * {{zoom_factor}}  
    || ' ' ||

    || ', ' ||
    CAST(TRUNC(request_lng / {{zoom_factor}},2) AS numeric) * {{zoom_factor}}  
    || ' ' ||
    CAST(TRUNC(request_lat / ({{zoom_factor}} * {{stretch_factor}}),2) AS numeric) * ({{zoom_factor}}*{{stretch_factor}}) + sign(request_lat)*(.01 * {{zoom_factor}} * {{stretch_factor}})
    || ', ' ||
    CAST(TRUNC(request_lng / {{zoom_factor}},2) AS numeric) * {{zoom_factor}} + sign(request_lng)*(.01 * {{zoom_factor}})
    || ' ' ||
    CAST(TRUNC(request_lat / ({{zoom_factor}} * {{stretch_factor}}),2) AS numeric) * ({{zoom_factor}}*{{stretch_factor}}) + sign(request_lat)*(.01 * {{zoom_factor}} * {{stretch_factor}})
    ||'))') as geography

此时，配置单元不支持空间查询
