如何替换列值

Question

我需要将所有信用卡的最后10个号码更改为**********

例如49601111111111到4960**********。

请帮忙

Answer 1

即使信用卡中的位数未知或不同且最多包含19位数，也可以使用此功能。根据标准卡号，最多应有19位ES7

<强>查询：

card_number

  

PS - 在案例卡中包含Florin Ghita的更新已超过20位。   学分： select substr('01234567890123456789',1,length('01234567890123456789')-10) || '**********' from dual; ---Output `0123456789**********` with Credit_Card_details AS ( select '1234567890123456789' as CARD_NUMBER from dual ) select CARD_NUMBER AS String, length(CARD_NUMBER) AS string_length, REPLACE(CARD_NUMBER,substr(CARD_NUMBER,length(CARD_NUMBER)-10+1),'**********') AS New_string, length(REPLACE(CARD_NUMBER,substr(CARD_NUMBER,length(CARD_NUMBER)-10+1),'**********')) AS New_string_length from Credit_Card_details

Answer 4

尝试此查询：

jquery.ajaxSetup({
    dataFilter: function (data, type) {
        //modify the data

        return data;
    }
});
