在 SSRS 中创建硬编码数据集时出错

Question

正在尝试为本季度的几个月的 SSRS 报告创建硬编码数据集。我有这个：

SELECT CASE @Quarter
  WHEN 'Q1' THEN (
    SELECT 'January' as months, '01' as month_number
    UNION ALL
    SELECT 'February','02' 
    UNION ALL
    SELECT 'March', '03')
  WHEN 'Q2' THEN (
    SELECT 'April' as months, '04' as month_number
    UNION ALL
    SELECT 'May','05' 
    UNION ALL
    SELECT 'June', '06')
  WHEN 'Q3' THEN (
    SELECT 'July' as months, '07' as month_number
    UNION ALL
    SELECT 'August','08' 
    UNION ALL
    SELECT 'September', '09')
  ELSE (
    SELECT 'October' as months, '10' as month_number
    UNION ALL
    SELECT 'November','11' 
    UNION ALL
    SELECT 'December', '12')
END

但是我收到了这个错误：

Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

之前我尝试使用 table 变量：

DECLARE @Months TABLE (months VARCHAR(9), month_start VARCHAR(2));

IF @Quarter = 'Q1' 
  INSERT INTO @Months VALUES ('January','01'), ('February','02'), ('March','03')
ELSE IF @Quarter = 'Q2'
  INSERT INTO @Months VALUES ('April','04'), ('May','05'), ('June','06')
ELSE IF @Quarter = 'Q3'
  INSERT INTO @Months VALUES ('July','07'), ('August','08'), ('September','09')
ELSE
  INSERT INTO @Months VALUES ('October','10'), ('November','11'), ('December','12')

Select * FROM @Months

但是我得到了错误：

The Declare SQL construct or statement is not supported.

有人知道我如何让它在 SSRS 数据集中工作吗？

Answer 1

也许是这样的。

Declare @Quarter varchar(2) = 'Q1'

Select months,month_number From (Values 
('01','January','Q1'),('02','February','Q1'),('03','March','Q1'),
('04','April','Q2'),('05','May','Q2'),('06','June','Q2'),
('07','July','Q3'),('08','August','Q3'),('09','September','Q3'),
('10','October','Q4'),('11','November','Q4'),('12','December','Q4')
) N(month_number,months,Qtr)
Where Qtr=@Quarter

Returns

Months   Month_Number
January  01
February 02
March    03

Answer 2

尝试创建包含所有月份和季度的 CTE。

WITH MONTHS AS (
SELECT 'January' as months, '01' as month_number, 'Q1' [quarter]
UNION ALL
SELECT 'February','02', 'Q1'
UNION ALL
SELECT 'March', '03', 'Q1'
UNION ALL
SELECT 'April' as months, '04' as month_number, 'Q2'
UNION ALL
SELECT 'May','05', 'Q2'
UNION ALL
SELECT 'June', '06', 'Q2'
UNION ALL
SELECT 'July' as months, '07' as month_number, 'Q3'
UNION ALL
SELECT 'August','08', 'Q3'
UNION ALL
SELECT 'September', '09', 'Q3'
UNION ALL
SELECT 'October' as months, '10' as month_number, 'Q4'
UNION ALL
SELECT 'November','11', 'Q4'
UNION ALL
SELECT 'December', '12', 'Q4')
SELECT * FROM MONTHS
WHERE [quarter] = @Quarter

如果有帮助请告诉我。
