SQL-多行一列变为多行一列

Question

我有以下查询：

select convert(varchar(32),tas.complete_by_dt,101)+': '+tas.notes [Task] 
from TX_SOL_TASK tas where customer_no=230459

它为每个值返回一行，而我希望每个值只包含一行。 这是当前返回的内容：

Task

Answer 1

尝试以下动态枢纽：

DECLARE @customer_no INT = 230459;

DECLARE @sql NVARCHAR(MAX) = N'', @cols NVARCHAR(MAX) = N'';

SELECT @cols += STUFF((SELECT ',' + QUOTENAME(CONVERT(VARCHAR(32),complete_by_dt,101))
                       FROM dbo.TX_SOL_TASK 
                       WHERE customer_no = @customer_no
                       GROUP BY CONVERT(VARCHAR(32),complete_by_dt,101)
                       FOR XML PATH('')), 1, 1, '');

SET @sql = N'SELECT *
  FROM (SELECT  CONVERT(VARCHAR(32),complete_by_dt,101) Completed,
                notes
        FROM dbo.TX_SOL_TASK
        WHERE customer_no = @customer_no
        ) AS d
  PIVOT (MIN([notes]) FOR [Completed] IN (' + @cols + ')) AS p;';

EXEC sp_executesql @sql, N'@customer_no INT', @customer_no;
