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
