如何在列表pymssql中循环INSERT值？

Question

我尝试在for循环中插入数据，但它在将一些数据提交到数据库后崩溃我假设它因为我尝试INSERT到许多数据。 所以我想要一些建议来处理这个问题

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

我遇到了同样的问题。 我的输入数据类型是float32。 我将它更改为float64后，它的工作原理。 你可以尝试一下。
