Question

我需要一些帮助。我在sql 2012中创建了一个视图，该视图将使用人员ID＃并显示输入日期和在该日期输入的余额。我试图转换余额甚至尝试增加10日的入场日期和余额金额字段。

我文件中的balance_amount在小数点前不超过5位，小数点后6位。

我需要输出：

people_org_code_id | entry_date1 | balance1 | entry_date2 | balance2
--------------------------------------------------------------------
001234567            01/01/2018     2455.33   02/26/2018     358.33
005212222            01/24/2018     25.00

等等，直到它到达entry_date15和balance15。

我到目前为止的代码是：

    SELECT people_org_code_id, 
   [entry_date1]      AS entry_date1, 
   [balance_amount1]  AS balance1, 
   [entry_date2]      AS entry_date2, 
   [balance_amount2]  AS balance2, 
   [entry_date3]      AS entry_date3, 
   [balance_amount3]  AS balance3, 
   [entry_date4]      AS entry_date4, 
   [balance_amount4]  AS balance4, 
   [entry_date5]      AS entry_date5, 
   [balance_amount5]  AS balance5, 
   [entry_date6]      AS entry_date6, 
   [balance_amount6]  AS balance6, 
   [entry_date7]      AS entry_date7, 
   [balance_amount7]  AS balance7, 
   [entry_date8]      AS entry_date8, 
   [balance_amount8]  AS balance8, 
   [entry_date9]      AS entry_date9, 
   [balance_amount9]  AS balance9, 
   [entry_date10]     AS entry_date10, 
   [balance_amount10] AS balance_amount10, 
   [entry_date11]     AS entry_date11, 
   [balance_amount11] AS balance_amount11, 
   [entry_date12]     AS entry_date12, 
   [balance_amount12] AS balance_amount12, 
   [entry_date13]     AS entry_date13, 
   [balance_amount13] AS balance_amount13, 
   [entry_date14]     AS entry_date14, 
   [balance_amount14] AS balance_amount14, 
   [entry_date15]     AS entry_date15, 
   [balance_amount15] AS balance_amount15

                      partition BY cc.people_org_code_id 
                      ORDER BY cc.entry_date)

您需要将演员表更改为演员表（cc.balance_amount AS decimal（11,6））

十进制数据类型定义如下：

DECIMAL（精确度，比例）

精确度是数字中的位数。比例是数量   数字小数点右边的数字。例如，   数字123.45的精度为5，比例为2。
