無法使用executemany執行ST_GEOMFROMTEXT

在Ubuntu 16.04上使用python 3.5和mysql 5.7.18，我無法在executemany語句中使用ST_GEOMFROMTEXT函數。無法使用executemany執行ST_GEOMFROMTEXT

使用此代碼：

print(query) 
    print(add_vals[-1:])   
    zip_cursor.executemany(query, add_vals[-1:])

我得到以下輸出：

INSERT INTO zipcodes (zipcode, name, area, pop, emp, emp_pay, households, location) VALUES (%s,%s,%s,%s,%s,%s,%s,%s); 
[["'54517'", "'CLAM LAKE, WI'", 201.441702, 112, 10, 600, 59, "ST_GEOMFROMTEXT('POINT(46.145917 -90.930676)')"]] 
Traceback (most recent call last): 
    File "zip_parse.py", line 319, in <module> 
    main() 
    File "zip_parse.py", line 32, in main

    File "zip_parse.py", line 160, in insert_data

    return self.execute(stmt)

    self._handle_result(self._connection.cmd_query(stmt)) 
    File "/usr/local/lib/python3.5/dist-packages/mysql/connector/connection.py", line 488, in cmd_query 
    result = self._handle_result(self._send_cmd(ServerCmd.QUERY, query)) 
    File "/usr/local/lib/python3.5/dist-packages/mysql/connector/connection.py", line 395, in _handle_result 
    raise errors.get_exception(packet) 
mysql.connector.errors.DataError: 1416 (22003): Cannot get geometry object from data you send to the GEOMETRY field

然而，通過聲明似乎在複製到mysql命令行就好了去：

mysql> INSERT INTO zipcodes (zipcode, name, area, pop, emp, emp_pay, households, location) VALUES ('54517','CLAM LAKE, WI',201.441702,112,10,600,59,ST_GEOMFROMTEXT('POINT(46.145917 -90.930676)')); 
Query OK, 1 row affected (0.05 sec)

過去我廣泛使用了ST_GEOMFROMTEXT函數，而且我非常自信這是將空間數據添加到幾何字段（字段'位置'具有類型'POINT'）的正確方法。正如所證明的那樣，它不需要引用它來在命令行上工作（這經常是我的經驗中的焦點）。

任何想法爲什麼這不與執行許多？

我有同樣的問題：

import pymysql 

point = 'POINT(18.16 -66.72)' 
geojson = '{ "type": "Point", "coordinates": [102.0, 0.0]}'

下面的代碼片段不起作用：

"INSERT INTO `zip`(`id`, `zip`, `location`, `geometry`) VALUES (NULL,100, ST_PointFromText('%s'), ST_GeomFromGeoJSON('%s'))" 
qparams = (point, geojson) 
cursor.execute(sql, qparams)

所以答案就是以這種方式來使用它：

"INSERT INTO `zip`(`id`, `zip`, `location`, `geometry`) VALUES (NULL,100, ST_PointFromText('"+ point +"'), ST_GeomFromGeoJSON('"+ geojson +"'))"
