如何将数字原样保存到mysql数据库？

Question

我需要将数字保存到数据库中，请参见示例。

• 当前我将数字保存为22.5，并在数据库中将其保存为22。

• 数据库中的数字设置为整数

  //sometimes $number can be "33.5" or "33" or "1" or "1.003"or "03"
  $sql = "INSERT INTO active (name, number) VALUES ('somename','$number')";
  

Answer 1

If you make your number column as DECIMAL data type, it will hold the decimal point with all numbers. Integer columns cannot hold decimal points.

If it is not your requirement, better use VARCHAR as data type (But NOT RECOMENDED).

Hope this helps.

Answer 2

First of all, you need to check the structure of active table. From your question, I understand that various types of number values is going to be saved to number column. And I guess the type of number column in active table is numeric for int types. For example, INT or BIGINT or any other integer types.

Here is what I'm usually doing. Just use varchar for number field. It might not sound like professional. But it's very easy to use. By doing so, you won't have any problem with saving numeric value to the column. I have got an similar issue before while saving latitude and longitude value to the table. And php has got many functions to get actual float or int value from string. So this is an easy and simple way to fix.

将数字/整数/浮点数保存到数据库中最简单可靠的方法之一是将它们转换为字符串，然后将其存储到数据库中。

注意：：您的数据库列类型应为字符串/文本类型。

此方法的优点之一是您可以克服int / float / double的限制。

$string_number = (string)$number;
$float_number = (float)$string_number;

Answer 4

如果要将数字另存为22.5并保存在数据库中。然后，您需要更改表的列结构。而不是将整数/整数设置为浮点型，然后将下一个设置为10,2 有关信息，请检查下面的屏幕短
