最近在工作遇到数据库中存的数据类型是: decimal(14,4)
当我使用python 读取到内存中时,总是带着 decimal字符, 再写入其它mysql表中时,数据类型为int型,导致数据入库不成功.
import pymysql # 创建数据库连接 con = pymysql.connect() sql = '''select created_time from schma.table LIMIT 10''' try: cur = con.cursor(cursor=pymysql.cursors.DictCursor) cur.execute(sql) except Exception as e: print(e) else: data = cur.fetchall() finally: cur.close() con.close() for d in data: created_time = d.get('created_time') print(created_time)
使用mysql的cast方法来转换
select cast(created_time as signed) AS created_time from schma.table
