如何在Python中使用SAS SWAT模块更改CASTable的数据类型

import swat

s = swat.CAS(host='your_sas_server', port=your_sas_port, username='your_username', password='your_password')

castable = s.CASTable('your_castable')

castable.dtypes()

castable['column_name'].astype('new_data_type')

castable.update()

import swat

# 连接到SAS服务器
s = swat.CAS(host='your_sas_server', port=your_sas_port, username='your_username', password='your_password')

# 加载CASTable
castable = s.CASTable('your_castable')

# 查看CASTable的数据类型
print(castable.dtypes())

# 更改CASTable的数据类型
castable['column_name'].astype('new_data_type')

# 更新CASTable
castable.update()
