如何在列表pymssql中循环插入值？

Question

我尝试在 for 循环中插入数据，但在将一些数据提交到数据库后它崩溃了我认为它是因为我尝试插入许多数据。所以我想要一些建议来解决这个问题

for value in list:
    cursor.execute("INSERT INTO table_name (filed1, filed2, filed3, filed4, filed5) VALUES (%d, %d, %d, %d, %d)", (var1, var2, var3, var4, var5))
    conn.commit()
conn.close()

    cursor.execute("INSERT INTO ScanEMAxEMAHistoryDay (SecurityNumber, EMA1, EMA2, CrossType, DayCross) VALUES (%d, %d, %d, %d, %d)", (id, item[0][0], item[0][1], value[0], value[1]))

Answer 1

我也遇到了同样的问题。我的输入数据类型是 float32。在我将其更改为 float64 后，它就可以工作了。你可以试试看。
