Question

在Pandas数据帧的列中给出以下类型的数据（Pandas数据类型是datetime64 [ns]：

Contract_EffDt
1974-02-01

我想将此（以及一些字符串和整数列）导入Oracle，如下所示：

import cx_Oracle as cx
.
.
.
cur.setinputsizes(25,25,255,255,25,25,25,255,255,25,25,cx.DATE,int)
cur=con.cursor()
cur.bindarraysize = 1000
cur.executemany('''insert into Table(Contract_ID,Plan_ID,Org_Type,Plan_Type,Offers_Part_D,SNP_Plan,\
EGHP,Org_Name,Org_Mkt_Name,Plan_Name,Parent_Org,Contract_EffDt,YYYYMM) values (:1,:2,:3,:4,:5,:6,:7,:8,:9,:10,:11,:12,:13)''', rows)
con.commit()
cur.close()
con.close()

如何让cx_Oracle识别我的datetime列是什么，并相应地插入它？正如您所看到的，我已经尝试过cx.DATE，但这不起作用。

提前致谢！

con = cx.Connection("table/"+pwd+"@server")

rows=dfc.values.tolist()
dfc['Contract_EffDt'] = pd.to_datetime(dfc['Contract_EffDt'])
dfc['Contract_EffDt'] = pd.to_datetime(dfc['Contract_EffDt'],format='%YYYY-%mm-%dd')
dfc['Plan_ID']=dfc['Plan_ID'].astype(str)
dfc.dtypes

cur.setinputsizes(25,25,255,255,25,25,25,255,255,25,25,cx.DATETIME,int)

con.commit()
cur.close()
con.close()

输出：

TypeError: expecting numeric data

cx_Oracle相当于datetime64 [ns]
