taos的execute语句占位符是对应类型占位还是%s可以为所有类型占位？

[myprospection]

cursor=conn.cursor()
placeholder=','.join(['%s']*len(data.dtype.names))
for row in data:
for i,value in enumerate(row):
if isinstance(value,np.datetime64):
row[i]=datetime64_to_datetime(value)

	row = tuple(row)
	cursor.execute(f"INSERT INTO {table}({','.join(data.dtype.names)}) VALUES({placeholder})",row)

我在网上看到%s占位符，然后execute时把实际数值放进去我实际操作的时候报错了
错误信息：
