无法使用executemany执行ST_GEOMFROMTEXT

问题描述：

在Ubuntu 16.04上使用python 3.5和mysql 5.7.18，我无法在executemany语句中使用ST_GEOMFROMTEXT函数。无法使用executemany执行ST_GEOMFROMTEXT

使用此代码：

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

我得到以下输出：

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)')"]]

    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，通过声明似乎在复制到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)

过去我广泛使用了ST_GEOMFROMTEXT函数，而且我非常自信这是将空间数据添加到几何字段（字段'位置'具有类型'POINT'）的正确方法。正如所证明的那样，它不需要引用它来在命令行上工作（这经常是我的经验中的焦点）。

任何想法为什么这不与执行许多？

答

我有同样的问题：

import pymysql 

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

下面的代码片段不起作用：

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

所以答案就是以这种方式来使用它：

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