我需要一些帮助。我在 sql 2012 中创建了一个视图，该视图将采用人员 id# 并显示输入日期和在该日期输入的余额。我尝试转换余额，甚至尝试从 10 增加输入日期和余额金额字段。

我文件中的 balance_amount 小数点前不超过 5 位，小数点后不超过 6 位。

我需要输出为：

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

依此类推，直到它同时达到 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)

您需要将您的演员表更改为 Cast(cc.balance_amount AS decimal(11,6))

十进制数据类型定义如下：

DECIMAL（精度，比例）

精度是数字中的位数。比例是数字中小数点右侧的位数。例如，数字 123.45 的精度为 5，小数位数为 2。
