如何使用python获取最终插入的sql记录数

Question

我有脚本可以读取数据并进行转换并使用 python 插入数据库

但是转换后的数据正在循环插入，因此当我尝试获取cursor.rowcount时，它显示每个插入而不是最终计数

下面是我尝试过的脚本

   try:
   
    conn = dbapi.connect(
    address="sapb101.sap.shome.net",
    port=30015,
    user="***",
    password="***",
    databasename='B1Q'
  
    )

    print("Succesful Connection to Hana Dev")
except:
    print("Unsuccesful Connection to Hana Dev")    

cur = conn.cursor ()
try:
    del_query = '''
        delete from "SAPTOM"."EL.ps.Tech::tbl.IBDbounrend_PY" where "LoadDt" = to_char(now(), 'YYYYMMDD')
        '''
    cur.execute(del_query)
    print('number of rows deleted', cur.rowcount)
except Exception as e:
    print("Error deleting query:", e)
query = '''
#select query
'''

cur.execute(query)
data = cur.fetchall()
number_rows = f"Total number of rows in table:  {len(data)}\n"
print(number_rows# 65 rows
for row in data:
    LoadDt = row[0]
    #print(LoadDt)
    FiscalWeek = row[1]
    InboundCaseVol = row[2]
    OutboundCaseVol6WCH =row[3]
    OutboundCaseVol6WWC =row[4]
    #print(LoadDt,FiscalWeek,InboundCaseVol,OutboundCaseVol6WCH,OutboundCaseVol6WWC)
   

    
    try:
        
        tgt_query = '''INSERT INTO"SAPTOM"."EL.ps.Tech::tbl.IBDbounrend_PY"("LoadDt","FiscalWeek","InboundCaseVol","OutboundCaseVol6WCH","OutboundCaseVol6WWC") VALUES (?,?,?,?,?) '''
        val = (LoadDt,FiscalWeek,InboundCaseVol,OutboundCaseVol6WCH,OutboundCaseVol6WWC)
        cur.execute(tgt_query, val)
        conn.commit()
        #print(cur.rowcount)
        number_rows_inser = f'Number of Records inserted successfully: {cur.rowcount}\n'

    except Exception as e:
        print("Error inserting data:", e)

当我尝试打印 cur.rowcount 时，它每次都给我 1

以下是输出

成功插入的记录数：1

成功插入的记录数：1

成功插入的记录数：1

但我想要如下输出：

成功插入的记录数：65条

请在这里提出您的想法，帮助我！

您可以使用枚举函数来获取迭代的索引并获取迭代的长度，这将获得插入的总行数

count = None
for index, row in enumerate(data):
    count = index

    number_rows_inser = f'Number of Records inserted successfully: len(count)\n'
