它在行cursor.executemany(sql_query, exported_data)上失败，并显示错误
It fails on the line cursor.executemany(sql_query, exported_data) with the error
TypeError: expecting numeric data.
我的相关代码:
cursor = con.cursor()
exported_data = [tuple(x) for x in df.values]
#exported_data = [str(x) for x in df.values]
sql_query = ("INSERT INTO ROUGHTABLE(species, date_posted, stock_id, pounds, money, trade_year, trade_month, trade_day, sector_name, ask)" "VALUES(:3, :1, :2, :4, :5, :6, :7, :8 'Sustainable Harvest Sector', '1')")
cursor.executemany(sql_query, exported_data)
con.commit() #commit to database
cursor.close()
con.close()
当我注释exported_data行并取消注释其下面的行时，它仍然会失败，但是这次出现错误
When I comment the exported_data line and un-comment the one below it, it still fails, but this time with the error
cx_Oracle.DatabaseError: ORA-01036: illegal variable name/number
研究这些错误，发现它们可能是由于绑定变量，无效的日期格式，试图导出字符串而不是dict等引起的.我不是SQL方面的专家，并且希望帮助解决此问题.
Researching these errors reveal that they could be due to bind variables, invalid date formats, trying to export a string vs a dict, etc. I am not an expert with SQL and would like help solving this.
感谢您的任何帮助.
推荐答案
看起来像数字列中有非数字值，不是吗?添加oracle表定义可以帮助解决问题所在.
Looks like there are non-numeric values in what looks like numeric columns, no? Adding the oracle table definition could assist as to where the issue is.
