如何在 OAS (Oracle Analytics Publisher) 中设置序列号

Question

我目前的结果：

没有。	A 栏	B 栏	C 栏
1	A	AB	col_amount
2			col_amount
3			col_amount
4	B	AS	col_amount
5			col_amount
6	T	电视	col_amount

我想得到：

没有。	A 栏	B 栏	C 栏
1	A	AB	col_amount
			col_amount
			col_amount
2	B	AS	col_amount
			col_amount
3	T	电视	col_amount

Answer 1

根据上一个问题，您可以在

DENSE_RANK

表达式中使用

CASE

分析函数。

给定样本数据：

CREATE TABLE table_name (Column_A, Column_B, Column_C) AS
SELECT '01', 'AB', 'col_amount' FROM DUAL UNION ALL
SELECT '01', 'AB', 'col_amount' FROM DUAL UNION ALL
SELECT '01', 'AC', 'col_amount' FROM DUAL UNION ALL
SELECT '02', 'OA', 'col_amount' FROM DUAL UNION ALL
SELECT '03', 'OE', 'col_amount' FROM DUAL UNION ALL
SELECT '03', 'OE', 'col_amount' FROM DUAL UNION ALL
SELECT '04', 'OE', 'col_amount' FROM DUAL UNION ALL
SELECT '04', 'XX', 'col_amount' FROM DUAL;

然后，如果您想根据

column_a

和

column_b

的变化进行编号，则：

SELECT CASE b_rn WHEN 1 THEN DENSE_RANK() OVER (ORDER BY column_a, column_b) END
         AS no,
       CASE a_rn WHEN 1 THEN column_a END AS column_a,
       CASE b_rn WHEN 1 THEN column_b END AS column_b,
       column_c
FROM   (
  SELECT column_a,
         column_b,
         column_c,
         ROW_NUMBER() OVER (PARTITION BY column_a ORDER BY column_b, column_c)
           AS a_rn,
         ROW_NUMBER() OVER (PARTITION BY column_a, column_b ORDER BY column_c)
           AS b_rn
  FROM   table_name
)

哪个输出：

不	COLUMN_A	COLUMN_B	COLUMN_C
1	01	AB	col_amount
空	空	空	col_amount
2	空	交流	col_amount
3	02	办公自动化	col_amount
4	03	OE	col_amount
空	空	空	col_amount
5	04	OE	col_amount
6	空	XX	col_amount

或者，如果您只想根据

column_a

的变化进行编号，那么您可以使用：

SELECT CASE a_rn WHEN 1 THEN DENSE_RANK() OVER (ORDER BY column_a) END
         AS no,
       CASE a_rn WHEN 1 THEN column_a END AS column_a,
       CASE b_rn WHEN 1 THEN column_b END AS column_b,
       column_c
FROM   (
  SELECT column_a,
         column_b,
         column_c,
         ROW_NUMBER() OVER (PARTITION BY column_a ORDER BY column_b, column_c)
           AS a_rn,
         ROW_NUMBER() OVER (PARTITION BY column_a, column_b ORDER BY column_c)
           AS b_rn
  FROM   table_name
)

哪个输出：

不	COLUMN_A	COLUMN_B	COLUMN_C
1	01	AB	col_amount
空	空	空	col_amount
空	空	交流	col_amount
2	02	办公自动化	col_amount
3	03	OE	col_amount
空	空	空	col_amount
4	04	OE	col_amount
空	空	XX	col_amount
