最近在工作遇到資料庫中存的資料型別是: decimal(14,4)
遇到的問題是:

1. 當我使用python 讀取到記憶體中時,總是帶著 decimal字元, 再寫入其它mysql表中時,資料型別為int型,導致資料入庫不成功.

import pymysql
# 建立資料庫連線
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)

2. 解決方案:
   使用mysql的cast方法來轉換

select
cast(created_time as signed) AS created_time 
from schma.table
