我正在尝试将excel.xlsm文件数据推送到sql php myadmin 这是我的代码，因为我创建了一个在数据库sql和excel.xlsm数据库之间进行查询的模块，因为xlsm中的列名不同于数据库sql中的列名 这是我的简单代码
from sqlalchemy import create_engine

all_data = pd.read_excel(r'' + mydir + 'Governance_Tracker - Copy -

all_data.replace('\n','', regex=True)
df = all_data.where((pd.notnull(all_data)), None)

print("Success")
rows = engine.execute("SELECT * FROM govtracker").fetchall()
print(rows)
但是我在终端中发现这些错误 回溯错误

答案 0 :(得分：0)
错误很明显，您的表中有一个名为te_1st_submission_date的列声明为
`te_1st_submission_date` DATE NOT NULL,
但是您尝试为此列插入一个空值
1048，“列'te_1st_submission_date'不能为空”）
可能是您的作业
data_dict['te_1st_submission_date'] = df['TE 1st Response date '][i]
包含一个空值
尝试为此添加有效值（并最终添加其他空值）
